[0025] Embodiment:

[0026] Referring to the attached Figure 1 , a part production mold of this embodiment includes a fixed mold 1. A movable mold 12 is arranged above the fixed mold 1. A plurality of injection holes 13 are opened on the movable mold 12. Among them, both the fixed mold 1 and the movable mold 12 are made of high-strength wear-resistant materials to ensure the long-term durability and accuracy of the mold. A molding cavity 2 is opened at the top of the fixed mold 1. The molding cavity 2 is used to accommodate and shape the injection material to ensure that the part can be formed according to the predetermined shape and structure.

[0027] Referring to the attached Figure 3 and Figure 4 , an ejection groove 3 is opened at the bottom of the molding cavity 2. An ejection block 4 adapted to it is arranged in the ejection groove 3. The cooperation between the ejection groove 3 and the ejection block 4 enables the ejection block 4 to move smoothly in the ejection groove 3. A machine base 5 is fixedly installed below the fixed mold 1, and the machine base 5 is communicated with the molding cavity 2. A limit washer 6 is fixedly installed on the top of the machine base 5. The internal dimension of the limit washer 6 is smaller than the dimension of the ejection block 4, thereby restricting the movement range of the ejection block 4 and preventing the ejection block 4 from moving into the machine base 5, ensuring the accuracy and safety of the demolding action. The cooperation between the ejection groove 3 and the ejection block 4 realizes the automatic demolding of the part, improves the degree of production automation, and reduces the complexity of manual operation.

[0028] Referring to the attached Figures 2-4, a screw rod 7 is rotatably installed on a machine base 5, and a guide rod 8 is fixedly installed on the machine base 5. Specifically, there are two guide rods 8, and the two guide rods 8 are arranged on both sides of the screw rod 7. Both the screw rod 7 and the guide rod 8 are vertically arranged. A lifting plate 9 is threadedly connected to the screw rod 7, and the guide rod 8 passes through the lifting plate 9, thereby realizing the limitation of the lifting plate 9, so that the lifting plate 9 can move longitudinally during the rotation of the screw rod 7. A top rod 10 is fixedly installed at the top of the lifting plate 9, and the top rod 10 is fixedly connected to the bottom of the ejector block 4. A driving assembly 11 for driving the screw rod 7 to rotate is arranged outside the machine base 5. The driving assembly 11 includes a motor 1101 fixedly installed on the side of the machine base 5. Pulley 1102 is fixedly installed on the output shaft of the motor 1101 and the bottom end of the screw rod 7. A transmission belt 1103 is arranged between the two pulleys 1102. The motor 1101 is connected to an external power supply. When in use, the motor 1101 is turned on. Under the action of the two pulleys 1102 and the transmission belt 1103, the rotation of the screw rod 7 can be realized. During the rotation of the screw rod 7, the longitudinal movement of the lifting plate 9 and the top rod 10 is realized.

[0029] Refer to the appendix Figure 3 , it should be noted that the longitudinal sections of the two guide rods 8 are both T-shaped, thereby restricting the movement range of the lifting plate 9.

[0030] The coordinated action of the screw rod 7, the guide rod 8 and the driving assembly 11 realizes the stable and accurate movement of the lifting plate 9, the top rod 10 and the ejector block 4, making the entire demolding process more efficient and reliable, and improving the production efficiency.

[0031] Refer to the appendix Figure 1 , on one side of the fixed mold 1, a discharge slope 14 is fixedly installed. The discharge slope 14 is used to guide the ejected parts to slide out of the mold smoothly, reducing the operation difficulty. A reinforcing frame 15 is fixedly installed between the bottom of the discharge slope 14 and the machine base 5. The reinforcing frame 15 enhances the connection stability between the discharge slope 14 and the machine base 5. A plurality of installation grooves are opened on the discharge slope 14, and a heat dissipation fan 16 is fixedly installed in the installation grooves. The installation of the heat dissipation fan 16 effectively reduces the temperature of the parts sliding on the discharge slope 14, improves the cooling efficiency, and speeds up the working efficiency.

[0032] In this application, the driving assembly 11 drives the screw rod 7 to rotate. Through the coordinated action of the screw rod 7, the guide rod 8 and the ejection mechanism, the stable and accurate movement of the lifting plate 9, the top rod 10 and the ejector block 4 is realized, making the entire demolding process more efficient and reliable, realizing the automatic demolding of parts, significantly improving the degree of production automation, reducing the complexity and time cost of manual operation, and thus enhancing the production efficiency.

[0033] Finally, the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
