A reverse plastic mold structure of front and rear molds

Abstract

The invention discloses a front die and rear die reversing plastic cement die structure. The front die and rear die reversing plastic cement die structure comprises a movable die core and a fixed diecore, wherein inclined guide columns are fixedly arranged on the surfaces of the left side and the right side of the movable die core; C-shaped sliding blocks are fixedly arranged on the surfaces of the left side and the right side of the fixed die core; two extruding holes are formed in the middle part of the surface of the fixed die core; a die fixing embedding part is movably arranged in each extruding hole, and a cylindrical spiral groove is formed in the middle part of each die fixing embedding part; flowing channel embedding parts are movably arranged in the spiral grooves; a plurality of glue feeding holes are formed in the flowing channel embedding parts; and two inclined flow guide holes are formed in the outer sides of the spiral grooves in the surfaces of the top parts of the die fixing embedding parts. According to the front die and rear die reversing plastic cement die structure, the plastic cement for processing sequentially flows through the glue inlet holes and glue homogenizing holes to be poured into a die groove; after glue pouring, cooling water is poured into the spiral grooves through the flow guide holes and then is drained into the die fixing embedding partsthrough the flow guide holes in the other end, thus the purposes of reducing the forming period and ensuring the size stability of the product are achieved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mold processing, in particular to a reverse plastic mold structure of front and rear molds. Background technique [0002] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Known as the "Mother of Industry". The structure of the existing molds is mostly a structure with a moving platen on the top and a fixed platen on the bottom. The surface of the product is easily damaged during the demoulding operation, which not only affects the processing process, but also affects the qua...

Problems solved by technology

The structure of the existing molds is mostly a structure with a moving platen on the top and a fixed platen on the bottom. The surface of the product is easily damaged during the demoulding operation, which not only affects the processing process, but also affects the quality of the product. Most of the molds are air-cooled. Setting the shape not only takes a long time, but also has low work efficiency and poor use effect
