Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] In the present invention, a transfer material is fed into a mold composed of male and female dies capable of joining and separating, and a pattern on the transfer material is aligned with the mold. After that, the transfer material is preformed according to the female mold, the mold is closed, the molten resin is injected into the cavity of the mold and cooled,
Then, the two molds are separated, and the base film of the transfer material is peeled off to obtain a molded product in which the pattern layer is transferred to the surface, which is a mold used in the simultaneous injection molding painting method. The present invention relates to a mold capable of obtaining a molded product in which no mark of a suction port remains on the surface.

[Prior Art] In this type of injection molding simultaneous painting method, when molding a product having a shallow rising shape, a transfer material having a plastic film as a base is inserted into a mold, and the resin is directly injected, Since the film of the transfer material is also molded along the mold by the pressure of the injected resin, simultaneous painting can be performed without difficulty. However, when painting on the cubic curve of a product with a deep rise (more than 4 mm),
Depending on the pressure of the injected resin, the transfer material was not sufficiently molded and a satisfactory painted product could not be obtained. Therefore, when painting a three-dimensional curved surface of such a deeply rising product, a method is used in which the base film of the transfer material is preformed in advance and then the resin is injected.

Conventionally, as a method of preforming such a base film, a similar mold, which is separate from the injection mold, is used for heating,
A method of vacuum forming and inserting the formed film into the cavity of the mold, or compressed air supplied from the molded product unloader or the fixed side mold in the cavity forming chamber of the mold by preheating the transfer material. And a method of dividing the movable cavity forming surface and sucking the transfer material through the gap.

[Problems to be Solved by the Invention] In a method of preforming a substrate film of a transfer material by using a separate similar die and inserting this into a cavity of a die, misalignment is likely to occur. In addition, the method of supplying compressed air from the unloader or the fixed mold cannot perform sufficient pre-molding only with compressed air, and if the cavity forming chamber of the mold is increased by compressed air, the unloader will be damaged. And also affects the cycle time, which is not preferable. Further, the method of dividing the cavity forming surface of the movable mold and sucking the heated film through the gap has a fatal defect that a trace of the suction port remains on the finished molded product.

[Means and Actions for Solving Problems] The present invention provides a mold capable of solving such problems and obtaining a beautiful molded product without a trace of a suction port on the surface of a painted molded product. It was provided.

A first aspect of the present invention is a female mold having a recess having an inner surface including one or more cavity forming surfaces and a surface other than the cavity forming surface on a parting surface, and can be joined and separated from the female mold. And a male mold for forming one or more cavities into which resin is injected between the cavity and the cavity forming surface at the time of joining with a female mold, and an opposing party when separating these molds from each other. A transfer material is arranged and positioned between the molding surfaces, and the transfer material is sucked to be guided along the inner surface of the recess of the female mold, and then the two molds are joined to form a cavity of the inner surface of the recess of the female mold. One or two or more cavities are formed by the surface and the male die, and the surface other than the cavity forming surface of the female cavity inner surface is brought into close contact with the male die with the transfer material interposed therebetween, and Injecting resin into the resin and painting at the same time as molding A mold for performing a suction hole for sucking the transfer material to the surface other than the cavity-forming surface of the female recess inner surface is obtained by opening.

The transfer material is sucked into the recess of the female mold and is guided along the inner surface of the recess.However, since the suction hole is opened on the inner surface of the recess other than the cavity forming surface, the mold is closed and the resin is injected into the cavity. Even if the molding is carried out, the traces of the suction holes do not remain on the surface of the molded product, so that a molded product having a beautiful surface can be obtained.

A second invention is a mold for simultaneous injection molding as described above, wherein a suction hole is provided in a parting surface other than the recess of the female mold, and the parting surface other than the recess of the female mold is provided. A groove is formed to connect the recess to the suction hole.

A third aspect of the present invention is the step of closing the communication opening of the groove of the female die with the male die, when the male die is joined to the female die (mold closing). Parts are provided.

As in the first invention, the transfer material is sucked into the female recess and is deformed along the inner surface of the recess, but the suction holes open on the parting surface other than the female recess, Since the groove that connects the hole and the female-shaped recess is open at the peripheral edge of the recess, there is no possibility of leaving a mark on the molded product in practical use. In the third invention, since the opening of the groove in the peripheral portion of the female mold is closed by the step of the male mold when the mold is closed, there is no danger that the groove will be formed on the molded product. To be prevented.

A fourth aspect of the present invention is the injection molding simultaneous painting die as described above, wherein a groove for communicating the recess with the suction hole is formed on a parting surface other than the recess of the female mold, Inside the groove, the outer end surface is flush with the parting surface other than the female concave portion, and the position where the groove disappears and the parting surface other than the female concave portion sinks into the groove. The slide block that can be selectively positioned at the retracted position where the groove appears is accommodated and arranged.

When the transfer material is placed on the female parting surface and heated and sucked, the slide block is in the retracted position, so the suction hole communicates with the female recess by the groove and the transfer material is sucked into this recess. To do. Thereafter, when the male die is joined to the female die (the die is closed), the slide block in the groove is advanced to the advance position to eliminate the groove, so that no trace of the groove remains on the molded product.

A fifth aspect of the present invention is the injection molding simultaneous painting die as described above, wherein a plurality of slides are provided around the cavity forming recess on a parting surface other than the cavity forming recess of the female mold, with intervals. While making a block accommodating recess,
An outer end surface of each of the slide block accommodating recesses projects from a parting surface other than the recess of the female mold and is located on the parting surface of the female mold between adjacent pairs of the slide block accommodating recesses. A slide that can be selectively positioned in a protruding position where a groove extending from the cavity forming recess is formed, and in an immersion position where the groove disappears by being flush with a parting surface other than the female recess. A block is housed and provided, and suction holes are provided which are opened in a parting surface other than the female recess and communicate with each of the grooves formed between adjacent pairs of the slide blocks in the protruding position. Is.

When the transfer material is sucked into the cavity forming recess of the female mold, the slide block in each slide block accommodating recess is in a protruding position, and a groove is formed to connect the cavity forming recess to the suction hole. When the male mold is joined to the female mold (the mold is closed), the slide block protruding from the parting surface other than the female recess by the parting surface other than the male protrusion does not contact the female recess other than the female recess. Since the groove disappears when it is pushed into an immersion position flush with the parting surface, no trace of the groove remains on the molded product.
