Intelligent forming mold for plastic foam sheet forming

Abstract

The invention discloses an intelligent forming mold for plastic foam sheet forming. The intelligent forming mold for plastic foam sheet forming comprises a mold body. A heat insulation plate is fixedto the upper end of the mold body, and a raw material box is fixed to the upper end of the heat insulation plate; and a guide plate is fixed to the bottom of the inside of the raw material box, an output groove is formed in the bottom of the raw material box in a penetrating mode, an input pipe is fixed to the inner wall of the output groove, an input groove is formed in the upper end of the moldbody in a penetrating mode, the input pipe penetrates through the heat insulation plate to be fixedly connected with the inner wall of the input groove, and a closed groove communicating with the input groove is formed in the top of inside of the mold body. The intelligent forming mold for plastic foam sheet forming has the advantages that after entering the mold body, raw material particles stayon a bearing plate, so that the bearing plate is lowered by the gravity of raw materials, then hydraulic oil enters a pushing groove, a connecting rod drives a closing plate to enter the closed groove, after the raw materials reach certain weight, input is stopped, good control over the input amount of raw materials is achieved, and the overall forming quality is further improved.

Description

technical field [0001] The invention relates to the technical field of foam boards, in particular to an intelligent molding die for molding plastic foam boards. Background technique [0002] Foam board refers to a white object that is made of expandable polystyrene beads containing a volatile liquid foaming agent, heated and pre-expanded, and then heated and formed in a mold. It has the structural characteristics of fine closed cells, and is mainly used for building walls. Body, roof insulation, composite board insulation, cold storage, air conditioning, vehicle, ship insulation, floor heating, decoration and engraving, etc. are widely used. [0003] At present, the molding process of the foam board is completed in the mold, and when the current molding mold heats the raw material, since the hot steam circulates from the inlet to the outlet, the hot steam is always transferred at the inlet position during the circulation process. There is a lot of heat at the outlet and les...
