Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold slide guide assembly. Background Technology
[0002] Injection molds are devices used to mass-produce complex-shaped parts using precision machining methods. They are widely used in the molding of thermoplastic products and are an important tool in plastic product manufacturing. Their performance and quality directly affect the quality of the final product. During the use of injection molds, to ensure that the two sets of molds can move along the accurate path during mold closing and opening, a sliding guide assembly is used to guide the moving mold.
[0003] During use, the slide guide assembly ensures the mold moves along a predetermined trajectory by sliding the guide sleeve on the guide post, thus guaranteeing the normal operation of the injection mold. However, existing slide guide assemblies are prone to high temperatures and wear during long-term movement of the guide post and guide sleeve, and wear also easily occurs when the mold slides in contact with the guide post. Therefore, this paper proposes a new slide guide assembly for injection molds to solve these problems. Utility Model Content
[0004] The purpose of this utility model is to provide a guide assembly for injection mold slide blocks, so as to solve the problems mentioned in the background art, such as high temperature and wear of the guide post and guide sleeve during long-term movement, and wear when the mold slides in contact.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a guide assembly for an injection mold slide, comprising a guide post, a left mold inserted through the guide post, and a right mold correspondingly provided on one side of the left mold, an injection groove provided on the left mold, and an injection hole correspondingly provided on the right mold, an injection nozzle provided on one side of the injection hole, and an ejector pin correspondingly provided on one side of the injection groove, a plurality of guide sleeves inserted through the guide post, and the guide sleeves respectively provided in the left mold and the right mold, and a plurality of rotating grooves provided on the outer wall of the guide post, and ball bearings embedded in the rotating grooves respectively;
[0006] The left and right molds have grooves at the guide posts at their four corners, and rubber plates are placed in the grooves. Multiple sets of bolts are spirally screwed onto the outer side of the rubber plates, and the other ends of the bolts are spirally screwed into the left and right molds respectively.
[0007] One end of the guide post is provided with a fixed pipe on both sides of the outer wall, and one end of the fixed pipe is provided with a cold water pipe inside the guide post. The fixed pipe is spiraled with a spiral pipe, and the spiral pipe is provided with a water inlet pipe. Another set of spiral pipes is provided with a water return pipe. The other end of the water inlet pipe is connected to the water source through a water pump, and the other end of the water return pipe is also connected to the water source.
[0008] Preferably, the guide sleeve forms a sliding structure with the guide post via balls.
[0009] Preferably, the rubber sheet is bolted to the left mold and the right mold to form a spiral locking structure.
[0010] Preferably, the fixed pipe has threads on its inner wall, and the water inlet pipe and the water return pipe are respectively connected to the fixed pipe through a spiral pipe to form a spiral lifting structure, and the water inlet pipe is connected to the cold water pipe through the spiral pipe and the fixed pipe.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The guide sleeve of the injection mold slide guide assembly forms a sliding structure with the guide post through the ball bearings. This ensures the smooth sliding of the guide sleeve while reducing wear between the guide sleeve and the guide post through multiple sets of ball bearings. The rubber plate of the device forms a spiral locking structure with the left mold and the right mold through bolts. This reduces the force when the four corners of the two molds come into contact, thus avoiding wear on the mold near the guide post without affecting the normal contact of the mold. The fixing tube of the device has threads on its inner wall, and the water inlet pipe and the water return pipe form a spiral lifting structure with the fixing tube through the spiral tube. The water inlet pipe forms a connecting structure with the cold water pipe through the spiral tube and the fixing tube. This ensures that the cold water pipe can cool the guide post through the spirally installed water inlet pipe and the water return pipe, thus avoiding the impact of high temperature caused by long-term use of the guide post.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] Please see Figure 1-4 This utility model provides a technical solution: a guide assembly for an injection mold slide, including a guide post 1, a left mold 2 inserted through the guide post 1, and a right mold 3 correspondingly provided on one side of the left mold 2, an injection groove opened on the left mold 2, and an injection hole correspondingly opened on the right mold 3, an injection nozzle 4 provided on one side of the injection hole, and an ejector pin 5 correspondingly provided on one side of the injection groove, a plurality of guide sleeves 6 inserted through the guide post 1, and the guide sleeves 6 are respectively provided in the left mold 2 and the right mold 3, and a plurality of rotating grooves are opened on the outer wall of the guide post 1, and ball bearings 7 are embedded in the rotating grooves respectively.
[0019] Furthermore, the guide sleeve 6 forms a sliding structure with the guide post 1 through the ball bearings 7, thereby reducing the friction between the guide sleeve 6 and the guide post 1 through multiple sets of ball bearings 7, thus avoiding wear caused by long-term sliding between the guide sleeve 6 and the guide post 1.
[0020] The left mold 2 and the right mold 3 have grooves at the four corners of the guide post 1, and rubber plates 8 are placed in the grooves. Multiple sets of bolts 9 are spirally screwed on the outside of the rubber plates 8, and the other end of the bolts 9 are spirally screwed into the left mold 2 and the right mold 3 respectively.
[0021] Furthermore, the rubber plate 8 is connected to the left mold 2 and the right mold 3 respectively by bolts 9 to form a spiral locking structure, thereby avoiding long-term contact and wear of the mold at the guide post 1 by the spirally installed rubber plate 8.
[0022] One end of the guide post 1 is provided with a fixed pipe 12 on both outer walls, and one end of the fixed pipe 12 is provided with a cold water pipe 13 inside the guide post 1. A spiral pipe 11 is spirally attached to the fixed pipe 12, and an inlet pipe 10 is attached to the spiral pipe 11. A return pipe 14 is attached to another set of spiral pipes 11. The other end of the inlet pipe 10 is connected to the water source through a water pump, and the other end of the return pipe 14 is also connected to the water source.
[0023] Furthermore, the fixed pipe 12 has threads on its inner wall, and the inlet pipe 10 and the return pipe 14 form a spiral lifting structure with the fixed pipe 12 through the spiral pipe 11. Thus, the spirally installed inlet pipe 10 and return pipe 14 ensure that the coolant can enter the cooling pipe 13. The inlet pipe 10 forms a communication structure with the cold water pipe 13 through the spiral pipe 11 and the fixed pipe 12. Thus, the cold water pipe 13 avoids the high temperature caused by long-term use of the guide column 1 from affecting itself.
[0024] Working principle: When using the injection mold slide guide assembly, rubber plates 8 are first installed on the left mold 2 and right mold 3 respectively using multiple sets of bolts 9. This reduces the contact force between the two molds, preventing wear on the guide post 1 and ensuring smooth sliding. The bolts 9 also facilitate periodic replacement of the rubber plates 8. Subsequently, the inlet pipe 10 and return pipe 14 are spirally installed on the fixed pipe 12 via the spiral tube 11. Coolant enters the cold water pipe 13 through the inlet pipe 10, spiral tube 11, and fixed pipe 12. Inside, the guide post 1 is cooled by the cold water pipe 13, thus avoiding the high temperature caused by long-term use of the guide post 1. The coolant can be circulated through the return water pipe 14. During the use of the injection mold, the guide sleeve 6 can slide on the guide post 1, thereby moving the left mold 2 to the right mold 3. At the same time, the friction between the guide sleeve 6 and the guide post 1 can be reduced by the multiple sets of ball bearings 7 on the guide post 1, thus avoiding wear caused by long-term movement of the guide post 1 and the guide sleeve 6. This is the usage process of the injection mold slide guide assembly.
[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
