Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a temperature control device for an injection mold. Background Art

[0002] Injection molds are widely used in the plastic product processing industry. Injection molds are generally suitable for thermoplastic plastic heating molding. Using the hot melt principle of thermoplastic plastics, the molten plastic is injected into the mold cavity of the injection mold temperature control device through the injection molding machine, and then cooled and shaped. The mold is opened to take out the plastic product.

[0003] At present, when the temperature control device in the injection mold is heated and molded, the heating device body and the molding mold are placed together, such as Figure 2 As shown, due to the high temperature in and around the molding cavity, the heating device body will be affected over time. At the same time, the closed design will increase the cost of use, which is very inconvenient. Therefore, we propose an injection mold temperature control device to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a temperature control device for an injection mold.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] Preferably, the four corners of the top plate are provided with connecting holes, and a first screw is passed through the connecting holes. The four corners of the upper end of the middle heating chamber are provided with threaded blind holes corresponding to the connecting holes, and one end of a first screw on the same side extends into a threaded blind hole on the same side.

[0008] Preferably, the arc-shaped limiting groove and the positioning groove are integrally formed.

[0011] Preferably, the second connecting plate is provided with two reinforcement holes.

[0012] In the present invention, during injection molding, the molding material is injected into the molding mold through the injection molding probe, and then heated and molded by the heater. After cooling, the lower end movable cabin is removed by the demoulding mechanism to take out the molded product. By providing arc-shaped limit grooves and positioning grooves on the top plate, the heater body and the injection molding probe are conveniently extended, thereby avoiding the influence of high temperature caused by the closed design on the heater body. At the same time, the closed shell structure and the corresponding long bolt costs can be saved. In addition, the first connecting plates on both sides of the lower end movable cabin are selected according to needs to correspond to the demoulding mechanism to ensure the stability of the connection.
