Novel fast-molding injection molding die

Abstract

The invention provides a novel fast-molding injection molding die. The novel fast-molding injection molding die comprises a baseboard, a movable die, a fixed die, a casting system and an ejection structure, and also comprises a fixed lock block, a filter, a gas discharge hole, a heating layer and a cooling layer, the baseboard is fixedly provided with the fixed die, the fixed die is provided with the casting system, the forefront side of the casting system is provided with the filter, the backmost side of the casting system is provided with the gas discharge hole, the heating layer is also arranged, a raw material injected to a complex injection molding die easily cools after a long time, and the heating layer avoids cooling of the injection molding raw material before injection molding when the raw material is injected, so the product molding yield is guaranteed. When the injection molding is completed, the heating layer is closed, and the cooling layer is started to cool a product and guarantee molding of the product, so the product can be ejected by the ejection structure.

Description

[0001] technical field [0002] The invention relates to the field of injection molding, in particular to a novel rapid prototyping injection mold. Background technique [0003] Today's injection molds generally cool the injection molding raw materials first and then perform the ejection operation during injection molding. In this way, sometimes the product will have ejection marks due to incomplete cooling during ejection, which will affect the appearance of the product in the slightest, and in severe cases. affect product quality. Today's mold injection molding is generally a product injection molding with a simple structure. When a product with a complex structure is required to be injected, the raw material enters the gating system and is extremely easy to solidify in the middle. In order to solve this problem, some people add an insulation layer to the mold. Although the insulation layer can be The raw materials are injected into the mold smoothly, but this prolongs ...

[0003] In today's injection molds, the injection molding raw materials are generally cooled first and then ejected. In this way, sometimes the product will be ejected due to incomplete cooling during ejection, which will affect the appearance of the product in the slightest, and in severe cases. affect product quality

Today's mold injection molding is generally a product injection molding with a simple structure. When a product with a complex structure is required to be injected, the raw material enters the gating system and is extremely easy to solidify in the middle. In order to solve this problem, some people add an insulation layer to the mold. Although the insulation layer can be The raw materials are injected into the mold smoothly, but this prolongs the cooling time and prolongs the production time of the product

Air is not allowed to appear in the injection mold, otherwise air bubbles will easily appear in the product, which will affect the quality of the product. Nowadays, the air cannot be completely eliminated, so we can only slow down the speed during operation and pay attention to the operation at all times.
