Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, and more specifically, to an injection mold for processing plastic products. Background Art

[0002] An injection mold is a tool used to produce plastic products. It injects molten plastic material into the mold and forms the product of the desired shape through pressurization and cooling. An injection mold usually consists of a mold base, a mold core, a mold cavity, a cooling system, and a discharge system. The injection mold plays a vital role in the plastic injection molding process. It can form plastic products with complex shapes, high dimensional accuracy, or with inserts in one go. The design and manufacturing accuracy of the injection mold directly affect the quality and production efficiency of the final product.

[0003] When processing plastic products, operators often use corresponding injection molds to perform injection molding operations on plastic products. Although existing injection molds have basic injection molding functions in actual use, the finished product will adhere to the inside of the lower mold after injection molding, which makes it inconvenient for operators to remove the finished product and perform subsequent injection molding operations. Forced peeling will increase the probability of damaging the quality of the finished product, so it needs to be improved. Utility Model Content

The other end of the output shaft of the power motor 13 is fixedly sleeved with a second threaded rod 14. The bottom end of the second threaded rod 14 passes through the fixing frame 12 and extends to the top of the base plate 1 and is threadedly sleeved with an upper mold 15. The outer surface of the upper mold 15 is movably connected to the inside of the vertical slot 16, and the top of the upper mold 15 is fixedly sleeved with an injection tube 17; when the operator needs to adjust the position of the upper mold 15, the power motor 13 is started at this time, which will cause the second threaded rod 14 to rotate. At this time, due to the limiting effect of the vertical slot 16, the upper mold 15 will move vertically up and down along the outer surface of the fixing frame 12.

[0028] The working principle and use process of this utility model:

[0029] First, start the power motor 13, which will cause the second threaded rod 14 to rotate, and make the upper mold 15 move vertically downward under the limiting action of the vertical groove 16. When the limiting rod 22 enters the interior of the upper mold 15, it will play a guiding role for the upper mold 15. Finally, when the upper mold 15 contacts the lower mold 21, the injection molding material is injected into the interior of the lower mold 21 through the injection tube 17. After cooling and molding, when the material needs to be taken out, start the drive motor 3, which will cause the rotating shaft 4 to drive the No. 1 bevel gear 5 to rotate, and the No. 2 bevel gear 6 drives the first threaded rod 7 to rotate together. The connecting rod 8 moves upward, thereby causing the connecting rod 8 to move upward, and causing the connecting rod 8 to drive the four vertical rods 9 to move upward together. When the connecting rod 8 moves, the injection molded product will be subjected to the elastic force of the No. 1 spring 11 in a compressed state, and in the process of the connecting rod 8 rising, the No. 1 spring 11 is gradually compressed, so that the force of the ejector rod 10 on the injection molded product to be ejected will gradually increase, which plays a buffering role on the injection molded product. When the vertical rod 9 completely enters the interior of the ejector rod 10, the ejection function of the injection molded product will be realized at this time, completing the purpose of making it easy for the operator to take out the injection molded product.
