During demoulding, the first template 6 and the second template 20 are separated. At this time, the pulling rod 24 will pull the finished product away from the mold core 17, and then the ejector bottom plate 11 and the ejector panel 9 will drive the ejector 13 to push outward, and the ejector 13 will push the finished product away from the mold, so that the demoulding work is completed quickly. After the demoulding work is completed, the first template 6 and the second template 20 will be closed again for injection molding. At this time, the return pin 8 and the spring 10 will drive the ejector panel 9 and the ejector bottom plate 11 to return to their original positions, so that the ejector 13 is also returned to their original positions, which prevents the ejector 13 from hitting the second template 20 when the first template 6 and the second template 20 are closed, thereby improving safety.

[0021] Further, a clamping block 18 is fixedly installed at one end of the first parting block 14, a guide column 19 is fixedly installed at one end of the first parting block 14, a second template 20 is arranged at one end of the guide column 19, a second parting block 21 is arranged at one end of the second template 20, a second parting surface 22 is provided on one side surface of the second parting block 21, a clamping groove 23 is provided on one side surface of the second parting block 21, a pulling rod 24 is fixedly installed at one end of the ejector panel 9, a mold panel 25 is arranged at one end of the second template 20, a fourth bolt 26 is connected to one end of the mold panel 25, an injection pipe 27 is arranged at one end of the mold panel 25, and a first template 6 is arranged at one end. There is a water inlet 28, a cooling water pipe 29 is arranged inside the first template 6, and a water outlet 30 is arranged at one end of the first template 6. Through the arrangement of the mold core 17, the block 18, the guide column 19, the second template 20, the second parting block 21, the second parting surface 22, the slot 23, the pulling rod 24, the mold panel 25, the fourth bolt 26, the injection pipe 27, the water inlet 28, the cooling water pipe 29 and the water outlet 30, during injection molding, through the mutual cooperation of the block 18 and the slot 23, the first parting block 14 and the second parting block 21 will be quickly and accurately closed together, the melted material will flow into the mold core 17, and the material will be shaped by the mold core 17.

[0022] Furthermore, the bottom plate 1 is fixedly connected to the mold leg 4 by the first bolt 3, and the mold leg 4 is fixedly connected to the first mold plate 6 by the second bolt 5. Through the setting of the mold leg 4, the mold leg 4 has a good supporting effect and provides space for the ejector panel 9 and the ejector bottom plate 11 to move.

[0023] Furthermore, the ejector panel 9 is fixedly connected to the ejector base plate 11 by a third bolt 12, and the return pin 8 forms a telescopic structure with the ejector panel 9 through a spring 10. Through the setting of the return pin 8 and the spring 10, the return pin 8 and the spring 10 will drive the ejector panel 9 and the ejector base plate 11 to return to their original positions, thereby preventing the ejector 13 from colliding with the second template 20.

[0024] Furthermore, the clamping block 18 forms a clamping structure with the second parting block 21 through the clamping slot 23. Through the setting of the clamping block 18 and the clamping slot 23, the cooperation between the clamping block 18 and the clamping slot 23 has a good positioning and fixing effect. When the mold is closed, the first parting block 14 and the second parting block 21 can be closed quickly and accurately.

[0025] Furthermore, the mold panel 25 is fixedly connected to the second mold plate 20 by a fourth bolt 26, and the water inlet 28 forms a water circulation structure with the water outlet 30 through the cooling water pipe 29.

[0026] Furthermore, a group of water inlet 28, cooling water pipe 29 and water outlet 30 are provided at one end of the first template 6 and the second template 20. Through the setting of the water outlet 30, cold water will flow out from the water outlet 30 to prevent the cold water temperature from rising and affecting the cooling effect.

[0027] Working principle: During injection molding, first put the hardware parts into the placement groove 16, the first template 6 and the second template 20 are closed, and the first parting block 14 and the second parting block 21 are also quickly positioned and closed through the cooperation of the clamping block 18 and the clamping groove 23. After the material is melted, it is injected into the mold core 17 through the injection pipe 27. The material is quickly molded in the mold core 17. At this time, cold water is injected into the cooling water pipe 29 through the water inlet 28. The cold water flows in the cooling water pipe 29 to quickly cool the material. In this way, the material is quickly cooled and molded to prevent the finished product from being deformed due to incomplete cooling. When demolding, the first mold The plate 6 and the second template 20 are separated. At this time, the pulling rod 24 will pull the finished product away from the mold core 17, and then the ejector bottom plate 11 and the ejector panel 9 will drive the ejector 13 to push outward, and the ejector 13 will push the finished product away from the mold, so that the demoulding work is completed quickly. After the demoulding work is completed, the first template 6 and the second template 20 will be closed again for injection molding. At this time, the return pin 8 and the spring 10 will drive the ejector panel 9 and the ejector bottom plate 11 to return to their original positions, so that the ejector 13 is also returned to their original positions, preventing the ejector 13 from hitting the second template 20 when the first template 6 and the second template 20 are closed, thereby improving safety.

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
