Sharp cooling and sharp heating highlight forming die

Abstract

The invention discloses a sharp cooling and sharp heating highlight forming die, belonging to the technical field of injection moulding. The invention comprises a cavity insert and is characterized in that the inside of the cavity insert is provided with a plurality of cooling water channels transversely and a steam line; the steam line contains a main gas inlet pipe, shunts and a main gas outletpipe; the main gas inlet pipe extends in the upper right of the cavity insert and extends to the middle part of the cavity insert; four shunts are connected on the main gas inlet pipe side by side and extend downwards; the tail parts of the four shunts are connected with the main gas outlet pipe; and the main gas outlet pipe is arranged transversely and extends out of the lower left of the cavityinsert. The invention solves the problem of the prior art that the injection moulding equipment can not realize the fast heating and fast cooling of the mould, thus the product has the appearance quality defects such as weld marks and flow marks, and provides the sharp cooling and sharp heating highlight forming die which has simple structure and can realize fast heating and fast cooling and achieve better injection moulding effect.

Description

technical field [0001] The invention belongs to the technical field of injection molding, in particular to a rapidly cooling and rapidly heating high-gloss forming mold. Background technique [0002] As one of the important molding methods in plastic processing, injection molding is widely used in various fields of industrial production. With the emergence of 3C and high-tech products, especially small and high-demand products, such as the emergence of various optical display products, people have higher and higher requirements for the precision, surface quality and strength of plastic products. Injection molding Molding technology has encountered unprecedented challenges. For some defects in the injection molding process, such as: weld marks, flow marks, poor appearance quality of injection molding products, etc., the ordinary injection molding process cannot fundamentally solve them. The key technical problem is that the rapid dynamic mold temperature change and control c...
