Waterway cooling structure of back mould

Abstract

The invention provides a waterway cooling structure of a back mould, which is used for enabling a design to be free of the limitation of a screw hole, an ejector pin hole and an insert hole, ensuring the normal arrangement of the design, and further ensuring the cooling of the back mould and the quality of a product. The waterway cooling structure of the back mould comprises a front mould core, a back mould core, a plate B, a base plate, a support pillar and a lower fixed plate, wherein the front mould core and the back mould core are mutually matched to form a diccavity; the back mould core is supported on the plate B; the base plate is supported on the support pillar; and the support pillar is supported on the lower fixed plate. The waterway cooling structure of the back mould is characterized in that: waterways sequentially penetrate through the support pillar, the base plate, the plate B from bottom to top so as to penetrate into the back mould core; a water pipe channel is formed on the lower fixed plate; the inner side of the water pipe channel is connected with the tops of the waterways; and the outer side of the water pipe channel is connected with cooling water.

Description

technical field [0001] The invention relates to the technical field of mold cooling structures, in particular to the water cooling structure of a rear mold. Background technique [0002] The existing water channel cooling structure of the rear mold is usually affected by structural features such as screw holes, thimble holes, and insert holes during the design process, which limits the design of the cooling water channel. Especially for some parts that need to be cooled by cooling water, due to the influence of thimble holes and screw holes, it is impossible to design cooling water channels. If cooling water is not designed, the molding cycle of the mold will be prolonged and the quality of the product will be affected. Contents of the invention [0003] The invention provides the water cooling structure of the rear mold, which makes the design not restricted by screw holes, thimble holes, and insert holes, and ensures the normal layout of the design, thereby ensuring the ...

[0002] The existing water cooling structure of the rear mold is usually affected by structural features such as screw holes, thimble holes, and insert holes during the design process, which limits the cooling water design

Especially for some parts that need to be cooled by cooling water, due to the influence of thimble holes and screw holes, the cooling water path cannot be designed. If the cooling water is not designed, the molding cycle of the mold will be prolonged and the quality of the product will be affected.
