Mould core insert part containing conformal cooling water channel

Abstract

The invention discloses a mould core insert part containing a conformal cooling water channel. The mould core insert part comprises a core body and a conformal cooling water channel arranged in the core body, wherein the core body and the conformal cooling water channel are integrally formed by a selective laser sintered material, the conformal cooling water channel comprises a plurality of parallel V-shaped water channel bodies, a pipe opening of the V-shaped water channel body at the head end is set as a water inlet, a pipe opening of the V-shaped water channel body at the tail end is set asa water outlet, the pipe openings of the two adjacent V-shaped water channel bodies are connected through U-shaped water channels, a tip part at the bottom of each V-shaped water channel body is setas a transition fillet, and a plurality of centre holes are further arranged in the core body. The mould core insert part disclosed by the invention not only can improve a cooling efficiency of a mould and shorten product cooling time, but also shortens a product forming period, improves a product production efficiency and reduces thermal residual stress of injection molded parts; furthermore, themould core insert part can improve dimensional accuracy of injection molded products and improve product quality.

Description

Technical field [0001] The invention relates to the field of injection molding molds, in particular to a mold core insert containing conformal cooling water channels. Background technique [0002] As we all know, injection molding is a high-efficiency manufacturing method of plastic parts, and its high-efficiency molding relies on injection molds. The injection molding process includes four stages: clamping, injection, holding pressure and cooling. In the entire injection molding cycle, cooling takes the longest time, occupying about 3 / 4 of the entire cycle. Therefore, the key to improving production efficiency lies in how to reduce To reduce this part of the cooling time, it is necessary to improve the cooling efficiency. In addition, due to the different structures of plastic parts, the difference in the cooling rate of different parts will cause uneven shrinkage of the plastic parts. To obtain more uniform cooling, it is necessary to make the temperature of each position of ...

AI Technical Summary

Problems solved by technology

The traditional cooling channel (jet type, bushing type, baffle type) cannot achieve uniform cooling of parts, and the processing is realized by drilling or using an inlaid mold structure, and the drilling can only process linear Cooling water channels, and plastic products often have complex curved surface structures, so the distance between the linear cooling water channels and the cavity surface is not equal, and it is difficult to achieve uniform cooling of parts
