Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an injection mold for a thermal insulation bucket with a long service life. Background Technology

[0002] Injection molds are tools used to produce plastic products, giving them a complete structure and precise dimensions. Injection molding is a processing method used for the mass production of certain complex-shaped parts. Specifically, it involves injecting molten plastic into a mold cavity under high pressure using an injection molding machine, followed by cooling and solidification to obtain the finished product. Currently, the production of insulated buckets is also accomplished through injection molding.

[0003] In actual use, during the process of molding the insulated bucket into the composite mold, the guide rod of the moving mold will experience frictional wear with the guide hole of the fixed mold. The traditional solution is to apply oil to the rod to alleviate wear, but this requires frequent maintenance and the service life of the rod cannot be guaranteed. Therefore, there is an urgent need for an insulated bucket injection mold with a long service life. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-lifespan injection mold for insulated buckets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-service-life thermos barrel injection mold includes a fixed mold and a moving mold. The bottom of the moving mold is provided with multiple guide pillars, which correspond to and fit with multiple guide sleeves provided on the upper part of the fixed mold. The bottom end of the guide pillar is limited and installed with a fitting block through a limiting groove. A support spring is provided between the fitting block and the guide pillar. The bottom of the fitting block is fitted with a wear-resistant sleeve by a buffer pillar. The bottom of the wear-resistant sleeve is fastened by a limiting plate.

[0007] In addition, a preferred structure is that a plurality of guide sleeves are installed on the upper part of the fixed mold, and the guide sleeves are used to guide the guide pillars when the mold is closed.

[0008] In addition, a preferred structure is that the bottom of the guide post is provided with multiple limiting grooves, the inner wall of the limiting grooves is provided with limiting holes, and the limiting holes extend into the interior of the guide post.

[0009] In addition, a preferred structure is that a plurality of engaging blocks are installed on the upper part of the buffer column, and a limiting post is connected to the inner side of the engaging blocks. The engaging blocks are installed in the limiting groove opened in the bottom wall of the guide column, and the limiting post is engaged in the limiting hole.

[0010] Furthermore, in a preferred configuration, the limiting hole and the limiting post are connected by a support spring.

[0011] Furthermore, in a preferred configuration, when the mating block is in its natural state, there is a certain gap between the upper wall of the mating block and the top wall of the limiting groove.

[0012] In addition, a preferred structure is that a wear-resistant sleeve is fitted onto the outer side of the buffer column, and a guide strip is provided on the outer wall of the buffer column, the guide strip corresponding to the vertical groove opened on the inner wall of the wear-resistant sleeve.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, during the mold closing process, the supporting spring, in conjunction with the guide column and buffer column, consumes the mold closing pressure, avoiding excessive pressure during mold closing that could exacerbate the wear of the guide column. A detachable wear-resistant sleeve is provided at the bottom of the guide column to reduce frictional wear in the early stage of mold closing and improve the overall service life of the guide column.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5A high-service-life thermos barrel injection mold includes a fixed mold 1 and a moving mold 3. The bottom of the moving mold 3 is provided with multiple guide pillars 4, which correspond to and fit with multiple guide sleeves 2 provided on the upper part of the fixed mold 1. The bottom end of the guide pillar 4 is limited and installed with a fitting block 10 through a limiting groove 7. A support spring 11 is provided between the fitting block 10 and the guide pillar 4. The bottom of the fitting block 10 is fitted with a wear-resistant sleeve 5 by a buffer pillar 6. The bottom of the wear-resistant sleeve 5 is fastened by a limiting plate 12.

[0023] Furthermore, multiple guide sleeves 2 are installed on the upper part of the fixed mold 1. The guide sleeves 2 are used to guide the guide pillars 4 when the mold is closed.

[0024] Furthermore, the bottom of the guide post 4 is provided with multiple limiting grooves 7, and the inner wall of the limiting grooves 7 is provided with limiting holes 8, which extend into the interior of the guide post 4.

[0025] Furthermore, multiple mating blocks 10 are installed on the upper part of the buffer column 6. The inner side of the mating block 10 is connected to the limiting post 9. The mating block 10 is installed in the limiting groove 7 opened in the bottom wall of the guide column 4, and the limiting post 9 is fitted in the limiting hole 8. The overall installation stability and accuracy of the mating block 10 and the buffer column 6 are ensured by guiding and connecting the limiting post 9 and the limiting hole 8.

[0026] Furthermore, the limiting hole 8 and the limiting post 9 are connected by a support spring 11.

[0027] Furthermore, in its natural state, the upper wall of the mating block 10 and the top wall of the limiting groove 7 have a certain gap, which satisfies the deformation and rebound of the support spring 11.

[0028] Furthermore, a wear-resistant sleeve 5 is fitted onto the outer side of the buffer column 6, and a guide strip 61 is provided on the outer wall of the buffer column 6, which corresponds to the vertical groove opened on the inner wall of the wear-resistant sleeve 5.

[0029] In this embodiment, the fixed mold 1 and the moving mold 3 are respectively installed and connected by the injection molding mechanism. Under the driving action of the injection molding mechanism, the moving mold 3 moves downward to perform the mold closing operation. The wear-resistant sleeve 5 provided at the bottom of the guide post 4 contacts and guides the guide sleeve 2 provided at the top of the fixed mold 1, thereby ensuring the mold closing accuracy of the fixed and moving molds.

[0030] In actual use, the wear-resistant sleeve 5 can effectively alleviate the wear and tear on the guide post 4 before mold closing. When the wear-resistant sleeve 5 and the guide sleeve 2 touch the bottom, that is, after the mold is closed, the moving mold 3 will still generate a certain downward force. At this time, the support spring 11 is compressed and deformed, and the force is consumed, so as to prevent the guide post 4 from directly bearing all the force.

[0031] In actual use, the limiting plate 12 can still be disassembled later. The limiting plate 12 is fastened to the bottom wall of the buffer column 6 by bolts. After the limiting plate 12 is disassembled, the wear-resistant sleeve 5 is replaced to ensure the overall service life.

[0032] Furthermore, a guide bar 61 is provided on the buffer column 6, and a corresponding vertical groove is provided on the inner wall of the wear-resistant sleeve 5 connected to it to fit the guide bar 61. The guide bar 61 is provided to ensure the installation stability of the wear-resistant sleeve 5.

[0033] In this invention, during the mold closing process, the support spring 11, in conjunction with the guide post 4 and the buffer post 6, consumes the mold closing pressure, thereby preventing excessive pressure during mold closing from aggravating the wear of the guide post 4. The bottom of the guide post 4 is provided with a detachable wear-resistant sleeve 5 to reduce the frictional wear generated in the front section of mold closing and improve the overall service life of the guide post.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
