[0024] The following will be combined with the drawings of the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1 , Figure 2 The utility model provides an embodiment: a plastic product molding mold, including a workbench 1, a first mold 2 is installed above the workbench 1, a second mold 3 is installed above the workbench 1, one side of the first mold 2 is fitted with one side of the second mold 3, a motor 5 is installed above the workbench 1, a rotating disk 6 is fixedly connected to the output end of the motor 5, two rotating grooves 10 are provided inside the rotating disk 6, a first mounting plate 8 is installed above the workbench 1, a first slide groove 9 is provided inside the first mounting plate 8, two sliders 11 are installed inside the first slide groove 9, one side of the two sliders 11 is fixedly connected to a sliding rod 12, and the two sliding rods 12 The outer walls of the two sliders 11 are installed inside the corresponding rotating groove 10, and the separated sides of the two sliders 11 are fixedly connected with the first sliding plate 13, and one side of the first mold 2 and one side of the second mold 3 are fixedly connected to one side of the corresponding first sliding plate 13. A sliding mechanism is installed above the workbench 1, and the sliding mechanism includes a second mounting plate 14. The lower surface of the second mounting plate 14 is fixedly connected to the upper surface of the workbench 1, and a second sliding groove 15 is opened inside the second mounting plate 14. Two second sliding plates 16 are slidably connected inside the second sliding groove 15, and one side of the two second sliding plates 16 is respectively fixedly connected to one side of the first mold 2 and one side of the second mold 3.

[0026] Specifically, the motor 5 drives the rotating disk 6 to rotate, which in turn drives the two sliding rods 12 to make the slider 11 slide in the first slide groove 9, so that the two first sliding plates 13 can drive the first mold 2 and the second mold 3 to move away from or closer to each other, and then make the second sliding plate 16 slide in the second slide groove 15. By driving the first mold 2 and the second mold 3 to move by the motor 5, the control signal can be quickly responded to, thereby quickly adjusting the movement state of the mold to meet the needs of injection molding processing and effectively improve work efficiency. Through the restrictions of the first slide groove 9 and the second slide groove 15, the stability of the movement of the first mold 2 and the second mold 3 is effectively improved.

[0027] Reference Figure 1 A first fixing plate 4 is fixedly connected to the upper surface of the workbench 1, one side of the first fixing plate 4 is installed on one side of the motor 5, a second fixing plate 7 is fixedly connected to the upper surface of the workbench 1, and the upper surface of the second fixing plate 7 is fixedly connected to the lower surface of the first mounting plate 8.

[0028] Specifically, the installation of the first fixing plate 4 helps to improve the stability of the motor 5 during operation, and the installation of the second fixing plate 7 supports the first mounting plate 8 .

[0029] Reference Figure 1 , Figure 3 , Figure 4 The upper surface of the workbench 1 is fixedly connected with a third fixed plate 17 on both sides, and two sliding columns 19 are installed on the adjacent sides of the two third fixed plates 17. Two springs 18 are fixedly connected to the adjacent sides of the two third fixed plates 17. One end of the spring 18 is fixedly connected to one end of the sliding column 19. The adjacent ends of the four sliding columns 19 are respectively slidably connected to one side of the first mold 2 and the second mold 3. The adjacent ends of the four sliding columns 19 are fixedly connected with a push plate 20. The interior of the first mold 2 and the interior of the second mold 3 are both provided with installation grooves 21, and the outer wall of the push plate 20 is installed inside the installation groove 21.

[0030] Specifically, when the first mold 2 and the second mold 3 are closed, the spring 18 is stretched. Under the action of the spring 18, the push plate 20 can fit more closely with the mounting groove 21, effectively improving the injection molding effect. When the first mold 2 and the second mold 3 are far apart, the spring 18 is no longer stressed. Under the action of the spring 18, the sliding column 19 can be moved closer to the third fixed plate 17, effectively avoiding the push plate 20 from clamping the molded plastic product too tightly and affecting demolding. Traditional molding mold devices mostly use devices such as ejector rods and ejector pipes with a small contact area with plastic products for ejecting molded plastic products, which are easy to cause damage to the molded plastic products. The setting of the push plate 20 greatly increases the contact area with the plastic products and effectively avoids damage to the molded plastic products.

[0031] Reference Figure 4 A material discharge hole 22 is provided inside the workbench 1 .

[0032] Specifically, the provision of the discharge hole 22 is conducive to the plastic product being directly dropped from the discharge hole 22 after being formed, thereby increasing the practicality of the device.

[0033] Working principle: When the molding mold is used, the rotating disk 6 is driven to rotate by starting the motor 5, and then the two sliding rods 12 are driven to make the slider 11 slide in the first slide groove 9, so that the two first sliding plates 13 can push the first mold 2 and the second mold 3 away from each other. When the first mold 2 and the second mold 3 move away from each other, the second sliding plate 16 slides in the second slide groove 15. When the first mold 2 and the second mold 3 move away from each other, the first mold 2 and the second mold 3 slide on the sliding column 19, so that the pushing plate 20 can be disengaged from the mounting groove 21, so as to realize rapid demoulding of the molded plastic product. The demoulded plastic product is discharged from the discharge hole 22. After the discharge is completed, the motor 5 is rotated in the opposite direction, so that the first mold 2 and the second mold 3 can be brought closer to each other. When the first mold 2 and the second mold 3 are closed, the spring 18 is stretched by force. Under the action of the spring 18, the pushing plate 20 can fit more closely with the mounting groove 21, thereby effectively improving the injection molding effect.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
