Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a three-pin reference structure. Background Technology

[0002] The three-pin reference design is mainly used on cold stamping die components. Each die set requires the design of three pins for large castings such as upper and lower base plates, punches, pressure plates, pressure rings, and wedge slides. The three pins on the die components are mainly used as references in the X and Y directions during machining. The plane of the three pins is used to engrave coordinate values. Usually, two are designed in the X direction and one in the Y direction. There are two types of three-pin structures in the existing die designs: one is a boss type, which protrudes 5 or 10 mm from the surface of the casting, and the other is a recess type, which sinks 5 mm into the surface of the casting.

[0003] However, while the boss-type three-pin structure is very easy to machine, it cannot be used on parts with profiles, such as punches and pressure plates. In addition, when designing three pins at the end of a raised base plate, it is not allowed to be designed as a boss to prevent the base plate from being unstable after flipping over. The recessed three-pin structure is used when designing three pin holes on the profile, but it can only be machined with a small tool and can only be machined in the Z-axis spiral milling. The Z-axis feed is only about 0.5mm per revolution. Not only the plane must be machined, but also the circumferential sidewalls, which reduces the machining efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a three-pin reference structure, which aims to solve the problems that the existing boss-type three-pin structure is not suitable for parts with profiles and the low processing efficiency of the recess-type three-pin structure.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a three-pin reference structure is provided for setting on a mold, including: a groove and a boss, wherein the groove is set on the mold; the boss is set in the groove, and a reference hole is provided on the boss.

[0006] Furthermore, both the groove and the boss are annular.

[0007] Furthermore, the depth of the groove on the mold gradually increases from the side closer to the boss and the side farther from the boss toward the center of the groove.

[0008] Furthermore, the groove includes two semi-circular grooves located at both ends of the boss and two rectangular grooves located on both sides of the boss, wherein the two ends of one semi-circular groove are respectively connected to one end of the two rectangular grooves, and the two ends of the other semi-circular groove are respectively connected to the other end of the two rectangular grooves.

[0009] Furthermore, the projection of the rectangular groove along the direction of the rectangular groove is arc-shaped.

[0010] Furthermore, the two ends of the semicircular groove are arc-shaped, corresponding to the projection of the rectangular groove along the direction of the rectangular groove.

[0011] Furthermore, the center of the reference hole is at the same position as the center of the semicircular groove.

[0012] Furthermore, the depth of the reference hole on the mold is greater than the depth of the groove on the mold.

[0013] Furthermore, both the groove and the boss are rectangular.

[0014] Furthermore, the height of the boss is lower than the height of the mold surface.

[0015] This utility model provides a three-pin reference structure for mounting on a mold, comprising: a groove and a boss. The groove is mounted on the mold; the boss is mounted within the groove, and a reference hole is provided on the boss. By mounting the boss within the groove and the reference hole on the boss, this utility model allows the three-pin reference structure to be used on parts with shaped surfaces. The groove design facilitates machining of the three-pin reference structure, resulting in higher machining efficiency. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0029] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0030] Combination Figure 1-4 As shown, this utility model provides a three-pin reference structure for being set on a mold 1, including: a groove 2 and a boss 3. The groove 2 is set on the mold 1; the boss 3 is set in the groove 2, and a reference hole 4 is provided on the boss 3.

[0031] In this embodiment of the present invention, when designing a three-pin structure on a component with a profiled surface, by setting the boss 3 in the groove 2, interference of the boss 3 with the processing of the profiled surface can be effectively avoided. The reference hole 4 is set on the boss 3. The setting of the groove 2 allows the three-pin reference structure to be used on the component with a profiled surface. Compared with the existing recessed three-pin structure which requires Z-axis helical milling, the setting of the boss 3 makes the three-pin reference structure easier to process and has higher processing efficiency.

[0032] Understandably, the three-pin reference structure is an optimized evolution of the existing boss-type three-pin structure and the recess-type three-pin structure. It can completely replace these two three-pin structures and solve the defects or deficiencies of these two three-pin structures, reduce the machining surface and machining time, reduce machining costs, make machining simpler and faster, improve machining efficiency, and improve the efficiency of straightening and alignment in the mold manufacturing process.

[0033] In some embodiments, both the groove 2 and the boss 3 are annular.

[0034] In this embodiment, the groove 2 and the boss 3 are designed in a ring shape, which helps the reference hole 4 to serve as a reference for machining the X and Y directions.

[0035] In other embodiments, both the groove 2 and the boss 3 are rectangular.

[0036] In this embodiment, the groove 2 and the boss 3 are designed as rectangles, which can be processed by casting, making the process relatively simple.

[0037] In practical applications, the three-pin reference structure often uses annular grooves 2 and bosses 3, which are easy to process and have high processing efficiency.

[0038] In some embodiments, the depth of the groove 2 on the mold 1 gradually increases from the side closer to the boss 3 and the side farther from the boss 3 toward the center of the groove 2.

[0039] In this embodiment, the depth of the groove 2 on the mold 1 gradually increases from the side closer to the boss 3 and the side farther from the boss 3 toward the middle of the groove 2. That is, the groove 2 gradually deepens from both sides toward the middle, which helps the processing of the boss 3 and avoids the groove 2 causing adverse effects on the processing of the boss 3.

[0040] In some embodiments, the groove 2 includes two semicircular grooves 21 located at both ends of the boss 3 and two rectangular grooves 22 located on both sides of the boss 3, wherein the two ends of the semicircular groove 21 are respectively connected to one end of the two rectangular grooves 22, and the two ends of the other semicircular groove 21 are respectively connected to the other end of the two rectangular grooves 22.

[0041] In this embodiment, the combination of two semi-circular grooves 21 and two rectangular grooves 22 facilitates the machining of the groove 2. The two semi-circular grooves 21 and two rectangular grooves 22 are symmetrically arranged, which helps the three-pin reference structure to serve as the reference for machining the X and Y directions.

[0042] In some embodiments, the projection of the rectangular groove 22 along the direction of the rectangular groove 22 is arc-shaped.

[0043] In this embodiment, the projection of the rectangular groove 22 along the direction of the rectangular groove 22 is arc-shaped, that is, the rectangular groove 22 as a whole is a cylindrical block, which is convenient for processing.

[0044] In some embodiments, the two ends of the semicircular groove 21 are arc-shaped, corresponding to the projection of the rectangular groove 22 along the direction of the rectangular groove 22.

[0045] In this embodiment, the two ends of the semicircular groove 21 are arc-shaped, corresponding to the projection of the rectangular groove 22 along the direction of the rectangular groove 22. This facilitates the docking of the semicircular groove 21 and the rectangular groove 22, as well as the processing of the semicircular groove 21.

[0046] In some embodiments, the center of the reference hole 4 is at the same position as the center of the semicircular groove 21.

[0047] In this embodiment, the center of the reference hole 4 is at the same position as the center of the semicircular groove 21, which helps to process the reference hole 4 and the semicircular groove 21, improves the processing efficiency of the three-pin reference structure, and facilitates the three-pin reference structure as a reference for machining the X and Y directions.

[0048] In some embodiments, the depth of the reference hole 4 on the mold 1 is greater than the depth of the groove 2 on the mold 1.

[0049] In this embodiment, the reference hole 4 being deeper than the groove 2 helps the three-pin reference structure serve as a reference for machining in the X and Y directions, thereby improving the efficiency of straightening and alignment during mold manufacturing.

[0050] In some embodiments, the height of the boss 3 is lower than the height of the surface of the mold 1.

[0051] In this embodiment, the height of the boss 3 is lower than the height of the surface of the mold 1, which allows the three-pin reference structure to be used on the part with the profile, and can effectively avoid the boss 3 interfering with the processing of the profile.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
