Technical Field

[0001] The utility model relates to the technical field of demoulding mechanisms, in particular to a rapid demoulding mechanism for sliders. Background Technique

[0002] In today's highly industrialized society, plastic products, with their advantages of light weight, durability, low cost, etc., have been widely used in many fields. From daily household items to complex industrial parts, plastic products are everywhere. And injection molding, as one of the main production methods of plastic products, is of great importance. An injection mold is a mold used in the injection molding process. By heating and melting plastic raw materials into a molten state, and then injecting them into the mold cavity under high pressure, and after cooling and solidifying, plastic products are finally obtained. The working process of an injection mold includes multiple steps. First is mold closing, where the moving mold and the fixed mold of the injection molding machine close to form a sealed cavity. Then, the injection molding machine injects the molten plastic into the mold cavity through the nozzle. After the injection is completed, in order to supplement the plastic amount reduced due to cooling shrinkage, it is necessary to continue to maintain a certain pressure for pressure holding. Subsequently, through the cooling channels inside the mold, the plastic is quickly cooled and solidified. Finally, the mold is opened, and the ejector mechanism ejects the plastic product.

[0003] In actual production, some products have side holes or side concavities inside for installation or fixation, etc. These side holes or side concavities make these products unable to be demoulded quickly and conveniently after injection molding, reducing work efficiency and increasing production costs.

The inner walls of the chutes 3 are slidably sleeved with long strip sliders 4. On the opposite surfaces of the two long strip sliders 4, moving seats 5 are fixedly connected. On the upper surface of the moving seat 5, a U-shaped block 10 is fixedly connected. On the upper surface of the moving seat 5, symmetrically distributed demolding sliders 6 are arranged. On the upper surfaces of the demolding sliders 6, an inclined groove 7 and a straight groove 8 are respectively opened. One end of the inclined groove 7 is communicated with one end of the straight groove 8. Inside the inclined groove 7, a cylindrical rod 9 is arranged. One ends of the two cylindrical rods 9 are fixedly connected to the upper surface of the moving seat 5, and the other ends of the two cylindrical rods 9 are fixedly connected to the inner top wall of the U-shaped block 10. On one side surface of the demolding slider 6, an inner side module 11 is fixedly connected;

[0026] The upper surface of the moving seat 5 is fixedly connected with a square block 12. One side surface of the square block 12 is fixedly connected with a connecting rod 13, and one end of the connecting rod 13 is fixedly connected with an inner center module 14.

[0027] One side surface of the moving seat 5 is fixedly connected with a force-receiving push block 15. The force-receiving push block 15 is provided with a first inclined surface 16, and a moving groove 17 is formed in the first inclined surface 16.

[0028] One end of the moving groove 17 penetrates and extends to the inner wall on one side of the force-receiving push block 15. A square sliding block 18 is slidably sleeved on the inner wall of the force-receiving push block 15.

[0029] One side surface of the square sliding block 18 is fixedly connected with a connecting block 19. The two side surfaces of the connecting block 19 are in contact with the two inner walls of the moving groove 17. The upper surface of the base 1 is fixedly connected with symmetrically distributed support plates 20;

[0030] The upper surfaces of the two support plates 20 are both fixedly connected with cross plates 21. Symmetrically distributed electric telescopic rods 22 are fixedly installed on the lower surface of the cross plate 21. One end of each of the two electric telescopic rods 22 is fixedly connected with a mounting plate 23. A driving block 24 is fixedly connected to the lower surface of the mounting plate 23. A second inclined surface 25 is provided on one side surface of the driving block 24, and the second inclined surface 25 of the driving block 24 is fixedly connected with one side surface of the connecting block 19.

[0031] Symmetrically distributed blocking blocks 26 are fixedly connected to the lower surface of the mounting plate 23. An outer mold mechanism 27 is fixedly installed on the upper surface of the base 1.

[0032] In the embodiment of the present application, the implementation principle of a rapid demolding mechanism for a slider is as follows: Step 1, start the electric telescopic rod 22, the mounting plate 23 drives the driving block 24 to move downward. The second inclined surface 25 of the driving block 24 is adapted to the first inclined surface 16 of the force-receiving pushing block. Thus, the movement of the driving block 24 drives the force-receiving pushing block 15 to move through the two adapted inclined surfaces. With the cooperation of the chute 3 and the long strip slider 4, the force-receiving pushing block drives the moving seat 5 to move, thereby driving the inner side module 11 and the inner center module 14 to move until one side surface of the inner side module 11 contacts one inner wall of the outer module. Due to the blocking effect of one inner wall of the outer module, the inner side module 11 stops moving. At this time, the moving seat 5 continues to drive the inner center module 14 to move. At the same time, one side surface of the blocking block 26 contacts one side surface of the demolding slider 6. And, since the cylindrical rod 9 continues to move driven by the moving seat 5, with the cooperation of the cylindrical rod 9 and the inclined groove 7, the two demolding sliders 6 expand away from each other, thereby driving the two inner side modules 11 to move away from each other until the cylindrical rod 9 moves into the straight groove 8. The two inner side modules 11 no longer move away from each other and the gap between them can just be filled by the inner center module 14. The moving seat 5 continues to move until the inner center module 14 just fills the gap between the two inner side modules 11. At this time, the two inner side modules 11 and the inner center module 14 just form a complete inner module. With the cooperation of the outer mold mechanism 27, injection molding can be carried out;

[0033] Step 2, after the injection molding is completed, since there are side holes or side recesses inside the product and the product cannot be quickly and conveniently demolded and taken out, start the electric telescopic rod 22 to drive the driving block 24 to contract in the reverse direction through the mounting plate 23. With the cooperation of the square slider 18 and the connecting block 19, the force-receiving pushing block moves in the reverse direction, thereby driving the inner center module 14 to move in the reverse direction through the moving seat 5. At this time, one side surface of the blocking block 26 has not separated from one side surface of the demolding slider 6, thus blocking the movement of the demolding slider 6. When the inner center module 14 is driven by the moving seat 5 to move out of the inside of the product, at this time the cylindrical rod 9 just moves in the reverse direction into the inclined groove 7, and one side surface of the blocking block 26 separates from one side surface of the demolding slider 6 and no longer plays a blocking role. The cylindrical rod 9 continues to move in the reverse direction driven by the moving seat 5. With the cooperation of the inclined groove 7, the two inner side modules 11 are driven by the demolding slider 6 to move relatively, so that the protrusions on the outer surface of the inner side module 11 are separated from the side holes or side recesses on the inner wall of the product. When completely separated, the cylindrical rod 9 just moves to one end of the inclined groove 7. Thus, driven by the cylindrical rod 9, the two inner side modules 11 also move out of the inside of the product. At this time, it is completely separated from the product, and the injection molded product can be taken out.

Any non-substantive changes and substitutions made by those skilled in the art based on the present utility model shall fall within the scope of protection required by the present utility model.
