Description

  The present invention relates to a part for cutting a product from a runner / spr with respect to a gate cutting means in a resin molded product take-out machine provided with a gate cutting means for cutting a resin molded product taken out from a resin molding machine into a product and a runner / sprue. The present invention relates to a gate cutting position data setting method and a resin molded product take-out machine in a resin molded product take-out machine that simply sets the movement position data of the chuck so that the gate is located.

In a resin molded product take-out machine that takes out a resin molded product by controlling movement of a chuck for holding a resin molded product between a mold of the resin molding machine and an open position outside the resin molding machine, for example, as shown in Patent Document 1 A gate cutting means is provided on the open position side of the resin molded product take-out machine, and the runner sprue of the resin molded product is cut at the gate in the resin molded product take-out cycle to separate the products.

The gate cutting means includes a plurality of cutting members that open and close the nipper blade by pneumatic pressure and open and close the nipper blade by an electromagnetic solenoid on the mounting frame facing the resin molded product held by the chuck. Installed and configured to match each product.

In the resin molded product take-out machine provided with the gate cutting means described above, in order to gate the resin molded product held by the chuck, the chuck is arranged so that the gate of the resin molded product is positioned between the open nipper blades. It is necessary to set the chuck movement position data for controlling the movement.

As the method of setting the moving position data of the chuck with respect to the gate cutting means, a method of directly inputting and setting the three-dimensional position data regarding each gate cutting position with respect to the moving origin of the resin molded product take-out machine as numerical data, the actual moving of the chuck There is a method of teaching and setting the chuck movement position data by positioning the gate of the resin molded product between the nipper blades that are controlled to open the gate cutting means.

However, in the former case, the three-dimensional position of the gate cutting position with respect to the moving origin must be accurately calculated and input, which requires a high level of skill and time and labor, and data setting work Has a problem of inefficiency.

In the latter, data can be set more easily than in the former, but it is necessary to set the movement position data while confirming whether the chuck has moved to each position with high positional accuracy. In addition, there is a problem in that it takes time and time and data setting work efficiency is poor.

In particular, in any moving position data setting method, after the moving position data is set, the chuck is actually moved based on the set moving position data, and the chuck has a high position accuracy with respect to a predetermined gate cutting position. It is necessary to verify whether or not it is moving with any of the setting methods, and it takes a lot of time and effort to set the movement position data including verification, so setting work efficiency Was extremely bad.

Each dimension data extracted from the CAD data of the gate cutting means 55 can be calculated and set, and a method of directly inputting numerical values for each movement position data as in the prior art, teaching by moving the chuck 47 to each position Compared to the input method, the data setting operation can be simplified, and the resin molded product removal operation can be made more efficient.

The above description has been described as a position that is set above the movable mold 21 near the standby position and coincides with the lowered position at the retreat position, but the present invention is not limited to the above-described embodiment, For example, the stand-by position is set above the fixed mold 19 and the lowered position is set close to the movable mold 21 of the fixed mold 19, and the reverse position is set from the movable mold 21 to the resin molded product. You may set to the arbitrary positions different from the descent | fall position which extracts 53 completely.

In that case, based on the respective dimension data extracted from the CAD data for manufacturing the resin molded product take-out machine 1, the resin molding machine 3, the base 7, the dies 19 and 21, and the chuck 47 that define the standby position. The movement position data of each chuck 47 may be set.

The above description is based on the resin molded product take-out machine 1 that takes out only the resin molded product 53, but a third traveling body (not shown) is provided on the fixed platen 5 side of the front and rear frame 37. The upper and lower frames provided with a lower pulling chuck (not shown) are supported by the third traveling body so as to move up and down, and a fixed mold together with the resin molded product 53 is supported. The present invention can also be implemented as a resin molded product take-out machine configured to take out the sprue 16.

Even in this case, it is necessary to control the movement of the sprue chuck to the standby position, the lowered position, the forward movement position, and the release position, similarly to the chuck 47 for the resin molded product. When setting the movement position data, the resin molded product take-out machine 1, the resin molding machine 3, and the gantry 7. The moving position data may be set based on the respective dimension data extracted from the CAD data for manufacturing the molds 19 and 21, the chuck 47 and the gate cutting means 55.

  In the above description, the gate cutting means 55 is attached to the open position side of the traveling frame 31 in the resin molded product take-out machine 1, but the gate cutting means 55 is not fixed to the traveling frame 31 and is in the open position. It may be arranged independently.

  The gate cutting means 55 is configured to cut the gate at the tip of the mounting arm 57 that extends in the front-rear direction with respect to the traveling frame 31, and thus on the movable side of the resin molding machine 3. On the other hand, it is good also as a structure attached to the fixed metal mold | die 19 side. In this case, the resin molded product 53 taken out from the movable mold 21 is rotated by 180 degrees by the attitude control member 49 and the attitude is controlled so as to face the fixed mold 19, and then the gate is cut. .
