[0026] When used specifically, the molding head 2 is fixed to the middle of the lower surface of the upper mold base 1 through the arrangement of the exhaust channel 4, the one-way valve 5, the piston block 6, the first spring 7 and the connecting rod 8, and is used for mold injection molding. Since the piston block 6 is in sliding connection with the cavity 3, when the air pressure inside the mold is too high, the air pressure will squeeze the piston block 6 to slide upward, thereby compressing the first spring 7. When the lower end of the piston block 6 exceeds the bottom end of the exhaust channel 4, the gas inside the mold will be discharged from the bottom of the cavity 3 through the exhaust channel 4 to the outside, and the exhaust effect is good, thereby improving the product quality. , to prevent the occurrence of problems such as air holes and bubbles. The one-way valve 5 prevents external gas from entering the interior of the mold and prevents the product from being contaminated by external air. When the air pressure inside the mold is stable, the piston block 6 slides down and resets under the elastic force of the first spring 7, thereby blocking the bottom of the cavity 3, realizing the automatic pressure relief function, and making the air pressure inside the mold more stable. The pull rod 9 is fixed to the top of the connecting rod 8. The pull rod 9 can be used to pull the piston block 6 through the connecting rod 8, so as to manually adjust the exhaust. Both methods are easy to use, ensuring the normal exhaust of the mold and increasing the convenience of use.

[0027] The middle of the upper surface of the upper mold base 1 and the molding head 2 is provided with an injection channel 10, and a baffle 11 is rotatably connected to one side of the upper surface of the upper mold base 1 close to the injection channel 10. When in use, the injection channel 10 is convenient for injection molding of the mold through the setting of the baffle 11. When the mold is not in use, the baffle 11 is rotated to block the injection channel 10 to prevent external dust from entering.

[0028] The lower surface of the upper die base 1 is movably connected to the lower die base 12, and a molding cavity 13 is provided in the middle of the upper surface of the lower die base 12. In specific use, through the setting of the molding cavity 13, the lower die base 12 and the upper die base 1 are matched with each other, leaving the molding cavity 13 to ensure product molding.

[0029] A sealing gasket 14 is fixedly connected to one side of the upper surface of the lower mold base 12 close to the molding cavity 13. In specific use, through the setting of the sealing gasket 14, when the upper mold base 1 and the lower mold base 12 are used, the sealing gasket 14 ensures the sealing performance of the upper mold base 1 and the lower mold base 12 during the injection molding process, which can further improve the sealing performance and ensure the injection molding quality.

[0030] The four corners of the lower surface of the upper die base 1 are fixedly connected with guide posts 15, and the four corners of the upper surface of the lower die base 12 are provided with guide holes 16. In specific use, by setting the guide posts 15, the guide posts 15 are inserted into the guide holes 16 for alignment before the mold is used to prevent the mold from shifting and ensure the quality of the product.

[0031] Support seats 17 are fixedly connected to both sides of the lower surface of the lower mold base 12, and a base 18 is fixedly connected to the lower surface of the support seat 17. A through hole 19 is opened in the middle of the upper surface of the base 18. In specific use, through the setting of the base 18, the base 18 and the support seat 17 are used in conjunction with each other to support and fix the lower mold base 12, and the output end of the cylinder of the injection molding equipment is connected to the slide plate 21, and the through hole 19 is convenient for the placement of the output end of the cylinder.

[0032] Both sides of the inner top wall of the support seat 17 are fixedly connected with guide rods 20, and the bottom of the outer surface of the guide rods 20 is slidably connected with a slide plate 21, and the outer surface of the guide rods 20 is sleeved with a second spring 22. In specific use, through the arrangement of the guide rods 20 and the second springs 22, the four corners of the slide plate 21 are slidably connected to the outer surfaces of the four guide rods 20. When the output end of the cylinder drives the slide plate 21 to move up and down, the guide rods 20 prevent the slide plate 21 from being offset in position and angle during the movement, thereby improving the accuracy of the displacement, and can play a role of limiting when ejecting, so as to achieve stability during reciprocating motion. The second spring 22 can increase the horizontal driving force when the slide plate 21 is reset, making it more convenient to reset.

[0033] The upper surface of the slide plate 21 is fixedly connected with a sleeve 23, and an ejector pin 24 is inserted into the interior of the sleeve 23. When in use, the ejector pin 24 is inserted into the interior of the sleeve 23, which is convenient for installation and disassembly, and is convenient for timely replacement when damaged, without the need to replace the entire part, saving costs. The ejector pin 24 and the slide plate 21 can realize the demoulding function of the mold under the action of the cylinder, which can make the mold ejection action smooth.

[0034] Working principle: In use, before use, the guide column 15 is inserted into the guide hole 16 for alignment. The sealing gasket 14 ensures the sealing of the upper mold base 1 and the lower mold base 12 during the injection molding process. Injection is performed into the mold through the injection channel 10. When the mold is not in use, the baffle 11 is rotated to block the injection channel 10 to prevent external dust from entering. The lower mold base 12 and the upper mold base 1 are matched with each other, leaving a molding cavity 13 to ensure product molding. When the air pressure inside the mold is too high, the air pressure will squeeze the piston block 6 to slide up, causing the first spring 7 to be compressed, and the gas inside the mold will pass through the exhaust from the bottom of the cavity 3. The air channel 4 is discharged to the outside to prevent problems such as air holes and bubbles. The one-way valve 5 prevents external gas from entering the interior of the mold to prevent the product from being contaminated by external air. When the air pressure inside the mold is stable, the piston block 6 slides down and resets under the elastic force of the first spring 7, blocking the bottom of the cavity 3 to achieve automatic pressure relief function. When the output end of the cylinder drives the slide plate 21 to move up and down, the guide rod 20 prevents the slide plate 21 from shifting in position and angle during movement. The second spring 22 can increase the horizontal driving force when the slide plate 21 is reset. The ejector pin 24 realizes the demolding function for the mold, which can make the mold ejection action smooth.
