[0002] An injection mold is a tool for producing plastic products. It is also a tool that gives plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain parts with complex shapes. Specifically, it refers to the high-pressure injection of heated and melted plastic into the mold cavity by an injection molding machine. After cooling and solidification, a molded product is obtained. Injection molds are divided into two types according to the molding characteristics: thermosetting plastic molds and thermoplastic plastic molds. According to the molding process, they are divided into transfer molds, blow molds, injection molds, etc. Among them, hot pressing molds can be divided into three types according to the overflow method: overflow type, semi-overflow type, and non-overflow type.

[0003] After the injection molding is completed, the cooling of the mold needs to be considered. Generally, the mold is cooled by external objects to achieve the effect of rapid plasticity. Most of the current molds do not have the effect of automatic cooling. In order to improve the cooling efficiency, this scheme proposes an injection mold that can improve the cooling efficiency.

[0007] Preferably, a sealing strip is fixedly installed on the top of the sealing plate around the heat conducting block.

[0008] Preferably, the intervals between the heat dissipation blocks are of the same size, and the bottoms of the heat dissipation blocks are connected to the cooling box.

[0009] Preferably, a water inlet is provided on one side of the cooling box, and a valve is fixedly installed at the water inlet on one side of the cooling box.

[0011] Preferably, the diameter of the upper mold is the same as the diameter of the lower mold.

[0012] The utility model has the following beneficial effects:

[0013] Coolant is injected into the cooling box through the valve. When the upper mold and the lower mold are connected together, the raw materials are then filled into the upper mold and the lower mold through the injection port, and the internal raw materials are waited for to be cooled and formed. At this time, the electric push rod is contracted, thereby driving the lower mold to move downward under the action of the first connecting plate and the second connecting plate. At this time, the bottom of the lower mold is connected to the heat conduction block, so that the heat of the lower mold can be quickly transferred to the heat dissipation block. Under the action of the coolant, the effect of rapid cooling can be achieved. After the cooling is completed, the electric push rod is expanded to separate the lower mold from the heat conduction block, thereby improving the cooling efficiency and achieving the effect of rapid molding.
