Description

[Detailed description of the invention] This invention is a molding machine that performs vacuum forming of a molded product between upper and lower molds, and in particular, it is easy to set the molded product into the molding machine and take out the product molded by the molding machine. Regarding the molding machine.

Examples of products molded by molding machines include instrument panels used as interior materials for automobiles. The present applicant previously proposed an efficient apparatus for manufacturing this instrument panel in Japanese Patent Application Laid-open No. 144478/1983.

This device consists of a unit sheet made by cutting a composite sheet into a predetermined length, which is made by pasting together a soft skin material and a foam sheet, and an ABS sheet whose surface is coated with adhesive.
A hard core material consisting of the above unit sheets and the like is prepared separately, and after these unit sheets and the core material are heated to a predetermined temperature, they are pressure-molded between the upper and lower molds of a molding machine.

In order to set the core material on the lower mold during molding, the worker must insert it himself into the space between the molds, and also use an ejector to remove the instrument panel product after molding. The product is pushed up and the worker enters between the molds to remove the product. For this reason, it is extremely inefficient and unfavorable in terms of workability and safety.

In order to solve this problem, it would be possible to install a device that automatically sets the core material into the molding machine and automatically takes out the product, but considering that the shape of the core material etc. varies. , is technically and cost-difficult.
