Description

Technical Field

[0001] This utility model relates to the field of metal mold production technology, specifically a testing fixture for metal mold production. Background Technology

[0002] Metal molds are precision tools that use their specific shapes and sizes to shape materials through pressure and other methods, thereby obtaining parts of the required shape and size. They themselves serve as "mothers" for large-scale "replication" of products. In the process of metal mold production, in order to ensure the production quality of metal molds, it is necessary to test the metal molds through testing fixtures. Therefore, China has authorized a utility model patent (publication number: CN221124158U) to provide a metal mold testing fixture. This testing fixture places the metal mold to be tested in a hardness testing component and tests the surface hardness of the metal mold by adjusting the hardness testing component. Furthermore, the limiting box can protect the mold from large displacement when subjected to the pressure generated by the hardness testing component, thereby improving the stability of the test.

[0003] However, this testing fixture only uses a limiting box to limit the placement of the metal mold to be tested. Since the shape and size of the limiting box are fixed, it is difficult to fix and limit metal molds of different shapes and sizes. Its application range is small, its applicability is poor, and it has certain limitations, which can easily affect the testing efficiency of the testing fixture. Utility Model Content

[0004] The purpose of this utility model is to provide a test fixture for metal mold production. Through the structural design of clamping plate, L-shaped extension plate and locking bolt, metal molds of different shapes and sizes can be conveniently fixed and limited, solving the problem of difficulty in fixing and limiting metal molds of different shapes and sizes.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a testing fixture for metal mold production, including an operating table with a fixed base. The upper surface of the fixed base is fitted with two clamping plates. Both ends of the clamping plates are provided with rectangular sliding grooves. The side surfaces of the clamping plates are provided with threaded holes that communicate with the interior of the rectangular sliding grooves. An L-shaped extension plate is fitted inside the rectangular sliding groove. A locking groove is provided on the side of the L-shaped extension plate. A locking bolt is fitted inside the threaded hole. One end of the locking bolt passes through the threaded hole into the rectangular sliding groove, and the other end of the locking bolt abuts against the inner wall of the locking groove.

[0007] Furthermore, two guide grooves are provided on the surface of the fixing base, and two guide blocks are provided at the bottom of the clamping plate, with the guide blocks cooperating with the guide grooves.

[0008] Furthermore, anti-slip strips are evenly distributed on the inner surface of the plywood, and rubber bumps are evenly distributed on the surface of the anti-slip strips.

[0009] Furthermore, the fixed base is provided with an assembly slot, in which a bidirectional screw is rotatably installed. Two drive blocks are fitted on the outer surface of the bidirectional screw. The drive blocks are fitted with the assembly slot, and the tops of the two drive blocks are respectively connected to the bottom center of the two clamping plates.

[0010] Furthermore, two circular grooves are formed in the assembly slot, and bearings are fitted in the circular grooves. The two ends of the bidirectional screw are respectively fitted with the inner rings of the two bearings. One end of the bidirectional screw passes through the circular groove to the outside of the fixed seat, and a turntable is provided at one end of the bidirectional screw.

[0011] Furthermore, the bottom of the fixed base is provided with a base plate, the bottom of which is connected to the surface of the operating table. Two hardness testing components are provided on the base plate, and the fixed base is located between the two hardness testing components.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, through the structural design of clamping plates, L-shaped extension plates, and locking bolts, allows the L-shaped extension plates to slide within a rectangular groove, causing their inner surfaces to abut against the longitudinal sides of the metal mold. The locking bolts then lock the L-shaped extension plates in place, effectively limiting the longitudinal sides of the metal mold with two pairs of L-shaped extension plates. This allows for convenient fixing and limiting of metal molds of different shapes and sizes, enriching the application range of this testing fixture, effectively improving its applicability, and ensuring its testing efficiency.

[0014] 2. This utility model utilizes a structure design of clamping plates and a bidirectional screw. The bidirectional screw drives the two clamping plates to move closer together on the surface of the fixing base, so that the inner sides of the two clamping plates fix and clamp the two sides of the metal mold on the platform. Furthermore, the anti-slip strips with rubber protrusions evenly distributed on the inner sides of the two clamping plates ensure that the metal mold is stably fixed between the two clamping plates. This effectively improves the testing stability of the metal mold, prevents the metal mold from shifting during testing and affecting the test results, and ensures the accuracy of the test data.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a testing fixture for metal mold production, including an operating table 1, a fixed base 2 on the operating table 1, two clamping plates 3 fitting on the upper surface of the fixed base 2, two guide grooves 202 formed on the surface of the fixed base 2, and two guide blocks at the bottom of the clamping plates 3. The guide blocks cooperate with the guide grooves 202 to ensure that the two clamping plates 3 slide stably towards each other on the fixed base 2. Anti-slip strips 303 are evenly distributed on the inner surface of the clamping plates 3, and rubber protrusions are evenly distributed on the surface of the anti-slip strips 303 to increase the contact area between the inner surface of the clamping plates 3 and the side of the metal mold. The friction between the clamping plates 3 improves the fixing effect of the two clamping plates 3 on the metal mold. The two clamping plates 3 are symmetrically arranged with the geometric midpoint of the fixing base 2 as the center. The bottom of the fixing base 2 is provided with a base plate 203, and the bottom of the base plate 203 is connected to the surface of the operating table 1. Two hardness testing components 7 are provided on the base plate 203. The fixing base 2 is located between the two hardness testing components 7. The hardness testing component 7 includes a fixing plate, and two electric telescopic columns are provided on the fixing plate. The output end surface of the electric telescopic columns is provided with a pressure sensor, which can facilitate the hardness testing of the metal mold to be tested fixed between the two clamping plates 3.

[0023] Both ends of the clamping plate 3 are provided with rectangular sliding grooves 301. The side surface of the clamping plate 3 is provided with threaded holes 302, which are connected to the interior of the rectangular sliding grooves 301. An L-shaped extension plate 4 is fitted inside the rectangular sliding grooves 301. A locking groove 401 is provided on the side of the L-shaped extension plate 4. A locking bolt 5 is fitted inside the threaded hole 302. One end of the locking bolt 5 passes through the threaded hole 302 into the rectangular sliding groove 301, and the other end of the locking bolt 5 abuts against the inner wall of the locking groove 401.

[0024] The fixed base 2 has an assembly groove 201, in which a bidirectional screw 6 is rotatably installed. The assembly groove 201 has two circular slots, in which bearings are fitted. The two ends of the bidirectional screw 6 are respectively fitted with the inner rings of the two bearings, which can realize the rotation effect of the bidirectional screw 6 in the assembly groove 201. One end of the bidirectional screw 6 passes through the circular slot to the outside of the fixed base 2. A turntable is provided at one end of the bidirectional screw 6 to facilitate the rotation of the bidirectional screw 6. Two drive blocks 601 are fitted on the outer surface of the bidirectional screw 6. The drive blocks 601 are fitted with the assembly groove 201. The tops of the two drive blocks 601 are respectively connected to the bottom center of the two clamping plates 3.

[0025] In use, the metal mold to be tested is placed on the platform between the two clamping plates 3 on the fixed base 2. Then, the turntable drives the bidirectional screw 6 to rotate in the assembly groove 201, so that the two driving blocks 601 on the bidirectional screw 6 slide towards each other in the assembly groove 201, so that the two clamping plates 3 are close to each other on the surface of the fixed base 2, and the inner sides of the two clamping plates 3 fix and clamp the two sides of the metal mold on the platform. The anti-slip strips 303 with rubber protrusions evenly arranged on the inner side of the two clamping plates 3 contact the sides of the metal mold, so that the static friction between the clamping plates 3 and the metal mold is greatly enhanced, thereby making the metal mold stably fixed between the two clamping plates 3.

[0026] When testing a metal mold, the two clamping plates 3 are brought close together to fix and limit the lateral sides of the metal mold. Then, the two locking bolts 5 on the sides of the two clamping plates 3 are rotated to separate one end of the locking bolt 5 from the corresponding locking groove 401, thereby releasing the locking bolt 5 from the restriction of the L-shaped extension plate 4. Then, the L-shaped extension plate 4 is pulled to slide in the rectangular slide groove 301, so that the inner surface of the L-shaped extension plate 4 abuts against the longitudinal side of the metal mold. Then, the corresponding locking bolt 5 is rotated again, so that the front end of the locking bolt 5 passes through the threaded hole 302 and enters the locking groove 401 on the L-shaped extension plate 4, and squeezes the inner wall of the locking groove 401, so that the locking bolt 5 locks the L-shaped extension plate 4. Then, the above operation is repeated so that the two L-shaped extension plates 4 at both ends of the two clamping plates 3 limit the longitudinal side of the metal mold. Thus, the extension and contraction of the L-shaped extension plate 4 in the rectangular slide groove 301 can be used to limit and test metal molds of different shapes and sizes.
