Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mold for a heat insulating container.
[0002]
[Prior art]
The conventional heat-insulating container has a drain hole for discharging the liquid in each container, but when a plurality of heat-insulating containers are stacked , the lower container is not contaminated with the liquid discharged from each container. A hole including the lid of the container and vertically penetrating the container wall was formed, and a communication hole communicating with the bottom of the container was formed in the vertical hole. When a vertical hole and a communication hole are formed by a mold as a drainage hole of such a container, conventionally, a core for the communication hole reaching the vertical hole from the bottom of the container is provided, and the core for the communication hole is provided. Either a device such as a piston that can be inserted and removed can be installed and inserted or removed, or a hole that extends from the outside of the container to the inside of the container through the vertical hole and reaches the inside of the container is formed. Of these, the hole outside the vertical hole was closed and placed later.
[0003]
[Problems to be solved by the invention]
However, in the case of a conventional configuration in which a device for taking out and inserting the communication hole core like a piston is installed and removed, a mold having a slightly complicated configuration is used, and the metal mold of a container to be mass-produced is used. It was not suitable as a mold. Also, in the case of a construction method in which a hole penetrating through the vertical hole toward the inside of the container from the outside of the container and reaching the inside of the container, and a hole outside the vertical hole among these holes is closed later, in producing the container, There is a drawback that the work of packing from the outside is required, the appearance is poor, and the process is complicated.
[0004]
The present invention solves the conventional drawbacks by simplifying the process by adding a simple improvement to the conventional mold of such a container.
[0005]
[Means for Solving the Problems]
The present invention has been developed in such a manner that only the force of the spring is used without using the force of the device, and these effects are used to the maximum.
[0006]
That is, the present invention provides a water draining vertical hole vertically penetrating a container wall of a foamed container formed by filling a material or the like into a cavity formed between an inner die and an outer die, as is the bottom may molding contact hole communicating with the longitudinal bore, set up a core for the vertical hole at a position bored vertical hole, core for communication hole for molding the contact holes, The inner die is supported by a shaft so that it can rotate, and is further urged by a spring in a direction to reach the core for the vertical hole. After the container is molded , the core for the communication hole is pulled in or molded. The core for the communication hole can be rotated in accordance with the movement of taking out the product.
[0007]
In this case, vertical holes are also formed at the four corners of the lid at positions corresponding to the vertical holes provided in the container body.
[0008]
In the embodiment in the drawings, the vertical holes provided at the four corners have been described. However, the vertical holes may be provided not only at the four corners, and a communication hole may be provided from the bottom of the container. It may be provided at any position.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, the present invention will be described with reference to the drawings.
[0010]
Raw material was filled in the cavity formed between the inner mold A1 and the outer mold A2, the four corners of the Yokabe 9 of the heat insulating container 1 is molded by foaming, in a state where the lid 2, and the lid A vertical hole 3 as a drain hole vertically penetrating including the four corners 2 and a communication hole 5 communicating with the vertical hole 3 from four corners of the bottom 4 inside the container body can be formed. Thus, the core 6 for the vertical hole and the core 8 for the communication hole are installed, and the core 8 for molding the communication holes 5... Can be supported by the inner mold A1 by the shaft 10 and can rotate. Then, the spring 7 urges the core 6 for the vertical hole to reach the core 6 for the vertical hole, and after the container 1 is formed , the core 8 for the communication hole can be moved in accordance with the movement of removing the molded product. It is something we can do.
[0011]
In this case, as an example, 4 has been a description about the longitudinal hole provided in the corner, the position of the longitudinal hole 3 can be opened at any such position.
[0012]
In a preferred embodiment, it is often provided at four corners, but this is not a limitation. Even in such a case, the relationship with the lid 2 is made so that the positions of the holes coincide with each other, as in the case of opening at the four corners.
[0013]
【The invention's effect】
As described above, the present invention urges the core for the communication hole by the spring in the direction to reach the core for the vertical hole, and moves the communication hole for the communication hole against the force of the spring in accordance with the movement of the molded product. Since the core is configured to rotate, the mold does not need to be finely operated by a machine, so that it is suitable for mass production and has effects such as long-term use.
