  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an up-and-down operation type automatic pressure-gelling molding machine for injection-molding an epoxy resin, which is a thermo-set plastic, as a molding material, A moving plate capable of moving up and down by tightening a mold is vertically operated to join or separate a mold and inject and cure a thermosetting liquid epoxy resin through a discharge port of a lower mold to form an angle The present invention relates to an up-and-down operation type automatic pressure-gelling molding machine for mounting an adjustable tilting device so that air inside a mold can be gathered at a point on the upper side of a moving mold and be easily discharged.

 In the conventional APG Clamping Machine (Horizontal type), a fixing plate for fastening a fixed mold and a moving plate for fastening a moving mold are formed to face each other in the longitudinal direction so that the moving plate is horizontally moved A mold is combined and a thermosetting plastic liquid epoxy resin is combined and injected through the lower part of the mold. Therefore, a parting line of the mold is formed in the longitudinal direction, and the molded product is also formed in the longitudinal direction. However, there are molded articles which allow the junction part of the mold to be formed only in the transverse (橫) direction because of the function and nature of the molded article. When molding such a product by a conventional left and right operation type automatic pressure gelling machine, another fixed and movable molds mounted on the fixing plate and the moving plate are manually assembled and inserted into the inside of the movable mold, The molds were moved horizontally, joined, and injection molded. That is, another mold is inserted into the mold and molded. After curing, the operation was performed in the reverse order of the above-mentioned operation, and the upper and lower bonded and separated molds were taken out to the outside and then manually separated to mold the molded product. Therefore, the production efficiency is low, the dependence of the workforce is high, and there is a problem in safety of work. In addition, there is a disadvantage in that the cost of reworking the mold is high, the manufacturing process is complicated, and the defect rate is high.
