[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-4As shown, a plastic product mold for easy part removal includes a base 1, a lower mold 2 mounted on the base 1, a control panel 3 mounted on the side wall of the lower mold 2, a mold cavity 4 inside the lower mold 2, an annular groove 5 on the side wall of the mold cavity 4, a ejector ring 6 fitted inside the annular groove 5, a plate groove 7 inside the lower mold 2, two rod grooves symmetrically formed inside the lower mold 2, a lifting plate 9 fitted inside the plate groove 7, two lifting rods 10 fixedly mounted on both sides of the lifting plate 9, the lifting rods 10 being fixedly connected to the ejector ring 6, a groove inside the lower mold 2, and a counterweight 11 fixedly mounted on the bottom side of the lifting plate 9. Two first buffer pads 12 are installed on the bottom side of the groove 7, and a second buffer pad 13 is installed on the bottom side of the groove. A steel wire rope 14 is fixedly installed on the lifting plate 9. A first guide wheel 15 is rotatably installed on the inner wall of the groove 7 via a wheel frame. A through hole is opened inside the lower mold 2, through which the steel wire rope 14 passes. A second guide wheel 16 is rotatably installed on the outer wall of the lower mold 2 via a wheel frame. Four sets of guide rods 17 are installed on the base 1. A fixing plate 18 is installed at the top of the guide rods 17. A hydraulic cylinder 19 is installed on the fixing plate 18, and a hydraulic rod 20 is installed on the hydraulic cylinder 19. During operation, the existing plastic product mold is used to process tableware. During the injection molding process, the molded part needs to be removed from the mold cavity 4, but it is difficult to remove the molded part conveniently, resulting in poor part removal convenience. The upper mold 22 moves down and engages with the lower mold 2, and then molten plastic is injected into the feed pipe 23. The molten plastic enters the mold cavity 4. After the molded part cools and solidifies, the hydraulic cylinder 19 operates, and the hydraulic rod 20 drives the mounting plate 21 to move vertically upward. The mounting plate 21 drives the upper mold 22 to move vertically upward, separating the upper mold 22 from the lower mold 2. At the same time, the upper mold 22 drives the connecting block 24 to move vertically upward, and the connecting block 24 pulls the steel wire. As the rope 14 moves upward, the wire rope 14 is gradually straightened. Then, the connecting block 24 continues to pull the wire rope 14 upward. The wire rope 14 slides on the first guide wheel 15 and the second guide wheel 16. The wire rope 14 pulls the lifting plate 9 at the other end to move vertically upward in the plate groove 7. The lifting plate 9 drives the two lifting rods 10 to move vertically upward in the rod groove 8. The two lifting rods 10 drive the top material ring 6 to move upward. The top material ring 6 lifts the molded part in the mold cavity 4, so that the molded part is suspended above the mold cavity 4. Then, the molded part is removed from the top material ring 6, realizing convenient and fast material removal of the molded part.

[0020] When the next part is being injection molded, the upper mold 22 moves down and engages with the lower mold 2, releasing the wire rope 14. At this time, the wire rope 14 no longer exerts tension on the lifting plate 9. Under the weight of the counterweight 11, the counterweight 11 drives the lifting plate 9 to move vertically downward. The lifting plate 9 drives the two lifting rods 10 to move vertically downward, and the two lifting rods 10 drive the ejector ring 6 to move downward, allowing the ejector ring 6 to return to its original position. Due to the large weight of the counterweight 11, the ejector ring 6 can be accurately locked on the inner wall of the mold cavity 4, achieving rapid reset of the ejector ring 6. This structure eliminates the need to directly remove parts from the mold cavity 4, avoiding injury to operators due to the high temperature of the lower mold 2. Furthermore, this structure does not contain motors, electric cylinders, or other equipment, avoiding excessive energy consumption. This structure improves the speed of part removal and enhances the convenience of part removal.

[0021] Please see Figure 5 As shown, an mounting plate 21 is installed on the bottom side of the hydraulic rod 20. The mounting plate 21 has four sets of rod holes. The mounting plate 21 is sleeved around the guide rod 17 through the rod holes. An upper mold 22 is installed on the mounting plate 21. A feed pipe 23 is installed on the upper mold 22. A connecting block 24 is fixedly installed on the side wall of the upper mold 22. The connecting block 24 is fixedly connected to the wire rope 14. During operation, existing plastic product molds have difficulty accurately positioning the upper mold 22 during the injection molding of tableware. The upper mold 22 is prone to displacement, resulting in poor stability. By fixing the upper mold 22 on the mounting plate 21, and sliding the mounting plate 21 around the guide rod 17 through the rod holes, the four sets of guide rods 17 can limit the mounting plate 21, thereby limiting the upper mold 22 and preventing the upper mold 22 from shifting in the vertical direction. This ensures that the upper mold 22 and the lower mold 2 are precisely aligned, which helps to improve the stability of the upper mold 22.

[0022] Working principle: In the process of injection molding tableware, existing plastic product molds require the molded part to be removed from the mold cavity 4, but this is difficult to do conveniently, resulting in poor ease of removal. The upper mold 22 moves downwards and engages with the lower mold 2, then molten plastic is injected into the feed pipe 23. The molten plastic enters the mold cavity 4, and after the molded part cools and solidifies, the hydraulic cylinder 19 operates, and the hydraulic rod 20 drives the mounting plate 21 to move vertically upwards. The mounting plate 21 then drives the upper mold 22 to move vertically upwards, separating the upper mold 22 from the lower mold 2. Simultaneously, the upper mold 22 drives the connecting block 24 to move vertically upwards, and the connecting block 24 pulls the steel wire rope 14 upwards. As the steel wire rope 14 is gradually straightened, the connecting block 24 continues to pull the steel wire rope 14 upward. The steel wire rope 14 slides on the first guide wheel 15 and the second guide wheel 16. The steel wire rope 14 pulls the lifting plate 9 at the other end to move vertically upward in the plate groove 7. The lifting plate 9 drives the two lifting rods 10 to move vertically upward in the rod groove 8. The two lifting rods 10 drive the ejector ring 6 to move upward. The ejector ring 6 lifts the molded part in the mold cavity 4, making the molded part suspended above the mold cavity 4. Then the molded part is removed from the ejector ring 6, realizing convenient and fast material removal of the molded part. When the next molded part is injection molded, the upper mold 22 moves down and engages with the lower mold 2, realizing the... When the wire rope 14 is released, it no longer exerts tension on the lifting plate 9. Under the weight of the counterweight 11, the counterweight 11 moves the lifting plate 9 vertically downwards. The lifting plate 9 then moves the two lifting rods 10 vertically downwards, which in turn move the ejector ring 6 downwards, restoring it to its original position. Due to the significant weight of the counterweight 11, the ejector ring 6 can be precisely engaged on the inner wall of the mold cavity 4, achieving rapid reset. This structure eliminates the need for direct removal of parts from the mold cavity 4, preventing injury to workers due to the high temperature of the lower mold 2. Furthermore, this structure does not contain motors, electric cylinders, or other such equipment, minimizing energy consumption. This structure improves the speed and convenience of picking up parts. In the process of injection molding tableware, existing plastic product molds have difficulty accurately positioning the upper mold 22, which is prone to displacement, resulting in poor stability. By fixing the upper mold 22 to the mounting plate 21, and sliding the mounting plate 21 around the guide rod 17 through the rod holes, the four sets of guide rods 17 can limit the mounting plate 21, thereby limiting the upper mold 22 and preventing the upper mold 22 from shifting in the vertical direction. This ensures that the upper mold 22 and the lower mold 2 are precisely aligned, which helps to improve the stability of the upper mold 22.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
