Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, specifically to a wear-resistant lateral positioning block for mold processing. Background Technology

[0002] In the field of mold processing, lateral positioning blocks are key components that ensure the mold closing accuracy and processing stability, and are widely used in various molds such as stamping dies and injection molds.

[0003] A patent document with publication number CN217494520U discloses a conical positioning block mechanism for preventing lateral force on a pressure plate. This mechanism includes an upper mold assembly, a lower mold assembly, an upper mold pressure plate, and a conical positioning component. The conical positioning component is configured as a combination of a primary and a secondary lateral force preventing conical positioning block. The primary lateral force preventing conical positioning block is embedded in the upper mold pressure plate, and the secondary lateral force preventing conical positioning block is embedded in the lower mold pad. A conical groove is formed on the lower surface of the primary lateral force preventing conical positioning block, and a conical protrusion is integrally formed on the upper surface of the secondary lateral force preventing conical positioning block. The conical protrusion is embedded in the conical groove, effectively balancing the pressure plate to counteract the lateral force generated during side cutting. This improves mold stability, reduces mold wear, and lowers mold maintenance costs.

[0004] In practical applications, the contact area between the positioning block and the mold assembly will gradually wear down due to long-term friction and pressure. The existing structure lacks a protective design to reduce contact wear, which may cause positioning gaps to appear in the contact area after a period of use due to wear, thus affecting the mold closing accuracy.

[0005] Therefore, this utility model proposes an anti-wear lateral positioning block for mold processing to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a wear-resistant lateral positioning block for mold processing, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a wear-resistant lateral positioning block for mold processing, comprising a first mold, a second mold, a guide post, and a sliding groove, wherein the first mold is provided with a guide post, and the second mold is provided with a sliding engagement in the sliding groove, wherein the sliding groove is provided at the end of the second mold; The first mold and the second mold are provided with a snap-fit ​​component, a buffer component, and an anti-wear component. The snap-fit ​​component is located at the four corners of the first mold, the buffer component is located on the snap-fit ​​component, and the anti-wear component is located at the four corners of the second mold.

[0008] Preferably, the positioning blocks in the snap-fit ​​assembly are fixedly disposed at the four corners of the first mold, and snap-fit ​​grooves are provided on both sides of the positioning blocks.

[0009] Preferably, the bottom end of the snap-fit ​​groove in the snap-fit ​​assembly is provided with an inclined groove, and the bottom of the inclined groove is provided with an arc-shaped groove.

[0010] Preferably, the buffer pad in the buffer assembly is arc-shaped and is fixedly disposed at the top of the positioning block.

[0011] Preferably, the snap-fit ​​protrusion in the anti-wear component is adapted to slide and snap-fit ​​in the snap-fit ​​groove. The snap-fit ​​protrusion is fixedly disposed on both sides of the second positioning block. The second positioning block is disposed at the four corners of the second mold. The bottom of the snap-fit ​​protrusion is provided with a slanted plate protrusion.

[0012] Preferably, the inclined plate protrusion in the anti-wear component is tightly engaged with the inclined groove, and an anti-wear protrusion is fixedly provided at the bottom end of the inclined plate protrusion, and the anti-wear protrusion is tightly engaged with the inclined groove and the arc groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By constructing a collaborative structure of a snap-fit ​​component, a buffer component, and an anti-wear component on the first mold and the second mold, the wear problem caused by the lack of protective design of the existing positioning block is specifically solved. The snap-fit ​​component, with the snap-fit ​​groove, inclined groove, and arc groove of the positioning block, forms a precise snap-fit ​​engagement with the snap-fit ​​protrusions on both sides of the second positioning block in the anti-wear component. At the same time, the tight fit design of the inclined plate protrusion with the inclined groove, the anti-wear protrusion with the inclined groove and the arc groove increases the contact area to disperse lateral pressure and reduce local friction loss. The arc-shaped buffer pad of the buffer component can buffer the collision impact force between the positioning block and related components when the mold is closed, avoiding wear caused by hard contact. The three work together to ensure the positioning accuracy of the mold closing. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of this utility model, not all embodiments, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0017] Example 1: Please refer to Figures 1 to 2 A wear-resistant lateral positioning block for mold processing includes a first mold 1, a second mold 2, a guide post 3, and a sliding groove 7. The first mold 1 is provided with the guide post 3, and the second mold 2 is provided with a sliding engagement in the sliding groove 7, which is located at the end of the second mold 2. The first mold and the second mold are provided with a engagement component 4, a buffer component 5, and an anti-wear component 6. The engagement component 4 is located at the four corners of the first mold 1, the buffer component 5 is located on the engagement component 4, and the anti-wear component 6 is located at the four corners of the second mold 2.

[0018] The positioning block 401 in the snap-fit ​​assembly 4 is fixedly installed at the four corners of the first mold 1, and snap-fit ​​grooves 402 are provided on both sides of the positioning block 401.

[0019] During use, when the molds are closed, the first mold 1 and the second mold 2 move closer to each other. The guide post 3 plays a preliminary guiding role to ensure that the mold closing direction is accurate. The components on the second mold 2 slide along the sliding groove 7. At the same time, the anti-wear components 6 at the four corners of the second mold 2 gradually approach the snap-fit ​​components 4 at the four corners of the first mold 1. At this time, the positioning block 401 in the snap-fit ​​component 4 serves as the core receiving component. The snap-fit ​​grooves 402 at both ends of the snap-fit ​​component 4 provide accurate positioning space for the access of the anti-wear component 6. This can initially limit the lateral displacement of the first mold 1 and the second mold 2, avoid collision of components due to positional deviation in the early stage of mold closing, lay the foundation for the accurate cooperation between the anti-wear component 6 and the snap-fit ​​component 4 in the later stage, and ensure the initial stability of the mold closing process.

[0020] Example 2: Based on Example 1, please refer to... Figures 2 to 3 The snap-fit ​​assembly 4 has a snap-fit ​​groove 402 at the bottom end with a sloping groove 403, and an arc groove 404 at the bottom of the sloping groove 403.

[0021] The buffer pad 501 in the buffer assembly 5 is arc-shaped and is fixedly installed at the end of the positioning block 401.

[0022] During use, as the mold closing process progresses, the anti-wear component 6 gradually enters the snap-fit ​​groove 402 of the snap-fit ​​component 4. At this time, the inclined groove 403 at the bottom end of the snap-fit ​​groove 402 acts as a guide, guiding the anti-wear component 6 to slide in smoothly and avoiding hard impact. At the same time, the arc-shaped groove 404 at the bottom of the inclined groove 403 can reduce the frictional resistance when the component slides, reducing the initial wear of the contact part. When the anti-wear component 6 initially contacts the snap-fit ​​component 4, the positioning block 401 snaps into the second positioning block 602. The arc-shaped buffer pad 501 at the end will first contact the corresponding part of the anti-wear component 6. Utilizing the elastic characteristics of its own arc structure, it buffers the impact force generated when the two come into contact, avoiding surface damage caused by hard collision between the positioning block 401 and the anti-wear component 6, further protecting the structural integrity of the snap-fit ​​groove 402, the inclined groove 403 and the arc-shaped groove 404, and extending the service life of the snap-fit ​​component 4.

[0023] Example 3: Based on Example 2, please refer to... Figures 3 to 4 The snap-fit ​​protrusion 601 in the anti-wear component 6 is adapted to slide and snap-fit ​​in the snap-fit ​​groove 402. The snap-fit ​​protrusion 601 is fixedly set at both ends of the second positioning block 602. The second positioning block 602 is set at the four corner ends of the second mold 2. The bottom of the snap-fit ​​protrusion 601 is provided with a sloping plate protrusion 603.

[0024] In the anti-wear component 6, the inclined plate protrusion 603 is tightly engaged with the inclined groove 403, and an anti-wear protrusion 604 is fixedly provided at the bottom end of the inclined plate protrusion 603. The anti-wear protrusion 604 is tightly engaged with the inclined groove 403 and the arc groove 404.

[0025] During use, in the mold closing process, the second positioning blocks 602 at the four corners of the second mold 2 drive the snap-fit ​​protrusions 601 at both ends to slide and snap into each other along the snap-fit ​​grooves 402 of the positioning blocks 401 on the first mold 1, ensuring accurate lateral positioning of the first mold 1 and the second mold 2. The inclined plate protrusion 603 at the bottom of the snap-fit ​​protrusion 601 moves with the snap-fit ​​protrusion 601 and gradually comes into close contact with the inclined groove 403 at the bottom of the snap-fit ​​groove 402. The inclined surface contact further disperses the lateral pressure. At the same time, the anti-wear protrusion 604 at the bottom of the inclined plate protrusion 603 comes into close contact with the inclined groove 403 and the arc groove 404. As the core component that directly contacts wear, it can withstand the main friction action and avoid direct wear of the snap-fit ​​groove 402, the inclined groove 403 and the arc groove 404. During the mold opening and closing process, this multi-part close-fitting structure always maintains accurate positioning and reduces the gap caused by wear. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
