A kind of injection mold with temperature control system

Abstract

The invention relates to the technical field of injection molds, and discloses an injection mold with a temperature control system, including a mold, a cavity, and a cooling water channel. A groove is opened on the rear side of the cooling water channel, and a groove is opened on the back of the groove. A moving slot, the top and bottom of the moving slot are provided with limiting slots, the inside of the groove is movable and connected with a spoiler, and the side of the spoiler away from the cooling water channel is fixedly installed with a moving plate, and the moving The left and right side surfaces of the plate are respectively in contact with the left and right inner walls of the moving slot, and the top and bottom surfaces of the moving plate are fixedly equipped with connecting blocks. This type of injection mold with a temperature control system pulls the handle so that the spoiler extends out of the cooling water channel, so that when the coolant flows inside the cooling water channel, the coolant and the spoiler come into contact to generate turbulence, and the coolant flow is realized. The rotation between the inside and the surface ensures that the inside and outside of the coolant can fully absorb heat, thereby improving cooling efficiency.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold with a temperature control system. Background technique [0002] Injection mold is a molding tool that solidifies molten plastic raw materials into products with certain shape and dimensional accuracy. [0003] The structure of the existing injection mold is as follows figure 1 As shown, the plastic raw material in the molten state is injected into the cavity through the injection molding machine, and then the cooling liquid with a lower temperature is passed into the cooling water channel to make the plastic product solidify and finalized. Since the inner wall of the cooling water channel is relatively smooth, the cooling liquid The flow state inside the cooling water channel is relatively stable, so that in the process of heat radiation from the injection mold to the center of the coolant, the internal coolant has already flowed away before absorbing ...

[0003] The structure of the existing injection mold is as follows figure 1 As shown, the plastic raw material in the molten state is injected into the cavity through the injection molding machine, and then the cooling liquid with a lower temperature is passed into the cooling water channel to make the plastic product solidify and finalized. Since the inner wall of the cooling water channel is relatively smooth, the cooling liquid The flow state inside the cooling water channel is relatively stable, so that in the process of heat radiation from the injection mold to the center of the coolant, the internal coolant has already flowed away before absorbing heat. In fact, only the coolant has the effect of absorbing heat and cooling Surface layer, so the cooling efficiency is low, and the internal structure of the mold is relatively simple, it does not have the function of temperature control, so it needs to rely on an external mold temperature controller to control the curing speed of the plastic, and the cost is high
