Problems solved by technology

In the process of cooling the mold, the residual heat of the electric heating element will affect the cooling efficiency instead, resulting in prolonged cooling time, which cannot really improve the injection molding efficiency
Although the induction heating coil that does not contact the mold does not have the problem of residual heat affecting the cooling efficiency, the induction heating coil can only heat the surface of the mold locally, and there is still a problem of poor heating efficiency for large molds

Embodiment Construction

[0017] see figure 2 As shown, it is a rapid injection molding system disclosed in the first embodiment of the present invention, which is used to make an injection molded part, which includes a mold 10, a clamping device 20, an injection molding machine 30, and a temperature control device 40 , a heating element 50, and a moving device 60.

[0018] refer to figure 2 As shown, the mold 10 includes a male mold 11 and a female mold 12, the male mold 11 and the female mold 12 have corresponding protrusions or concave structures respectively, after the male mold 11 and the female mold 12 are combined with each other, the male mold 11 A hollow mold cavity 13 is formed between the female mold 12 and used for injecting molding liquid into it. After the injection molding liquid filling the mold cavity 13 is cooled and solidified, an injection molded part whose shape matches the mold cavity 13 is formed. The male mold 11 has a sprue 111 connected to the mold cavity 13 , and the inj...

Abstract

The invention relates to a fast injection molding system, used for manufacturing an injection molding part so as to heat a die by a movable heating element. Before injection liquid is injected into a die cavity of the die, the heating element is moved and contacted with the die, thereby heating the die to a working temperature. After the temperature of the die achieves the working temperature, the heating element is moved and detached from the die so as to enable high temperature of the heating element to continuously heat the die. When a cooling fluid source cools the die, high temperature of the heating element can not influence the cooling efficiency. Because the heating element can not influence the subsequent cooling process, the heating power of the heating element can also be dramatically promoted, thereby accelerating the velocity of injection molding.

Description

【Technical field】 [0001] The present invention is related to injection molding, in particular to a rapid injection molding system that can increase the heating power of the mold and improve the efficiency of injection molding. 【Background technique】 [0002] In the rapid injection molding system, the mold needs to be heated to a relatively high working temperature to ensure that the injection molding liquid injected into the cavity maintains good fluidity and accelerates the filling of the entire cavity. Then the mold must be rapidly cooled to the mold opening temperature to open the mold for the injection molding to be taken out. [0003] refer to figure 1 As shown, it is a rapid injection molding system in the prior art, and its mold 1 has several channels 2 . These passages 2 can be connected head to tail in series, and then connected to the water inlet and outlet pipes; the passages 2 can also be arranged in parallel, and connected in parallel to the water inlet and ou...
