[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. The compression mold needs to be opened and separated to take out the plastic products or add plastic raw materials, which is called mold opening. On the contrary, the mold is closed and tightly closed, which is called mold closing. Therefore, molds play a key role in manufacturing. High-precision molds can improve production efficiency, reduce scrap rate and reduce costs.

The left and right upper ends of the lower mold 1 are both opened with two guide grooves 13, and the middle upper end of the lower mold 1 is installed with a molding cavity 14. When the upper mold 2 and the lower mold 1 are molded, the hydraulic cylinder drives the piston rod at its output end to extend and retract, and the piston rod is then inserted into the upper mold 2 and the lower mold 1 through the piston rod opening 12, and the upper mold 2 and the lower mold 1 are fixed and limited, so as to avoid the upper and lower molds being offset due to external shaking when the upper mold 2 and the lower mold 1 are molded, thereby improving the injection molding effect of the device.

[0026] Two connecting blocks 21 are installed at the front and rear of the outer surface of the upper mold 2, and two guide pillars 20 are installed at the left and right of the lower end of the upper mold 2. The upper mold 2 is aligned with the guide pillars 20 thereon and is inserted into the guide grooves 13 on the lower mold 1, thereby avoiding deviation when the upper mold 2 is moved downward to close the lower mold 1, thereby improving the molding quality of the mold.

[0027] A support seat 30 is installed at the left and right upper ends of the installation base 3 , and a support column 31 and a clamping column 32 are installed at the middle upper end of the installation base 3 .
