Problems solved by technology

[0003] In the prior art, when producing PVC sheets, its interior is usually a solid structure. When producing large-size sheets, affected by the specifications of the sheets, more raw materials are required for the sheets, and the larger specifications During the glue injection production of the sheet metal, due to the insufficient supply of rubber material, large irregular hollow areas are prone to appear inside the sheet metal, which affects the structural strength of the sheet metal and reduces the quality of the sheet metal.

Abstract

The invention discloses a PVC (polyvinyl chloride) material processing technology, and belongs to the field of PVC plastic processing, the PVC material processing technology can realize stable production of a PVC plate, a plurality of longitudinally arranged loose cores are inserted into a mold cavity, so that the interior of the formed plate is intermittently of a hollow structure, the structural strength of the plate is guaranteed, and meanwhile, the structural strength of the plate is improved. The material cost of a plate is effectively reduced, reduction of the quality of the plate is facilitated, the glue injection hole is formed in the outer end wall of the loose core, material injection operation can be conducted into the mold cavity through the loose core and the glue injection hole, the comprehensive uniformity of material injection of the device is effectively guaranteed, the probability that defective products appear in the device is reduced, and the production efficiency is improved. And the loose core is connected with the cross beam capable of moving back and forth, so that the loose core can be flexibly inserted into or pulled out of the mold cavity, and the material taking convenience after the production of the plate material is guaranteed.

Description

technical field [0001] The invention relates to the field of PVC plastic processing, and more specifically relates to a PVC material processing technology. Background technique [0002] PVC plastic, also known as polyvinyl chloride, is a polymer formed by the polymerization of vinyl chloride monomer (VCM) in peroxide, azo compound and other initiators or under the action of light and heat according to the mechanism of free radical polymerization. It is A common plastic, widely used in building materials, industrial products, daily necessities, etc. [0003] In the prior art, when producing PVC sheets, its interior is usually a solid structure. When producing large-size sheets, affected by the specifications of the sheets, more raw materials are required for the sheets, and the larger specifications During the glue injection production of the sheet metal, because the glue supply is not uniform enough, large irregular hollow areas are prone to appear inside the sheet metal, w...
