Description
Technical Field
[0001] This utility model relates to the field of mold hardness testing technology, and in particular to a hardness testing device for mold production and processing. Background Technology
[0002] Hardness testing devices used in mold manufacturing are crucial tools for ensuring mold quality. They accurately measure the hardness of molds, providing reliable data support for mold manufacturing and use. During mold production, hardness is a key indicator of mold material performance, directly affecting the mold's wear resistance, deformation resistance, and service life. Hardness testing devices can quickly and accurately obtain the hardness value of the mold surface or specific areas, ensuring compliance with design requirements and industry standards. These devices typically employ advanced measurement technologies, such as Rockwell hardness testers, Brinell hardness testers, or Vickers hardness testers, and can adapt to the testing needs of molds of different materials and shapes.
[0003] A search revealed that patent CN222259036U discloses a hardness testing device for mold manufacturing. This device uses four sets of clamping devices to hold the mold to be tested, preventing mold displacement during testing from affecting the accuracy of the hardness test. It also allows for the sliding slider to change to a different shaped clamping plate to fix molds of different shapes. However, this device still has drawbacks in practical mold installation: because the spacing of the slots on the push rod is fixed, it cannot be guaranteed that the slots on the through-slots and the slots on the connecting ears will align perfectly when the clamping plate contacts the mold. Therefore, the screw may not be able to be screwed into the through-slot, limiting its use. Furthermore, each set of clamping devices requires individual operation, making mold assembly and disassembly too cumbersome. Therefore, further improvements are needed. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hardness testing device for mold production and processing.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hardness testing device for mold production and processing, comprising a Rockwell hardness tester, a lifting base installed at the bottom of the Rockwell hardness tester, an installation component fixed at the top of the lifting base, and a detachable installation sleeve fixedly fitted onto the surface of the installation component, a base plate fixed on the upper surface of the installation sleeve, and a top plate provided above the base plate, a strip-shaped opening in the middle of the top plate, two clamping blocks slidably connected inside the strip-shaped opening, a guide rail fixed on the upper surface of the base plate, the two clamping blocks having an inclined design on the side away from each other, and a T-slot opened at the bottom of each clamping block, the T-slot fitting onto the surface of the guide rail and slidably connected to the guide rail, the base plate, the top plate, the guide rail and the two clamping blocks forming a fixing mechanism.
[0006] Furthermore, the Rockwell hardness tester is connected to a protective door via a hinge in the middle.
[0007] Furthermore, multiple vertical tubes are fixed to the upper side of the base plate, and vertical rods are slidably connected inside the vertical tubes, with the top of the vertical rods fixed to the lower surface of the top plate.
[0008] Furthermore, a second spring is fixed together on the upper surface of the base plate and the lower surface of the top plate.
[0009] Furthermore, the top wall of the T-shaped groove is provided with an inner groove, and a roller is rotatably connected inside the inner groove, with the bottom end of the roller fitting against the upper surface of the guide rail.
[0010] Furthermore, the mounting assembly includes a mounting base fixed to the top of the lifting seat, and the mounting base has a groove on its side wall. A first spring is fixed to the inner side wall of the groove, and a locking rod is fixed to the other end of the first spring. The mounting sleeve is fitted onto the surface of the mounting base, and the mounting sleeve has a locking hole on its side wall. The end of the locking rod away from the first spring is locked into the locking hole.
[0011] The beneficial effects of this utility model are:
[0012] 1. In use, this utility model provides a hardness testing device for mold production and processing, comprising a Rockwell hardness tester, a lifting base, a mounting assembly, a base plate, a top plate, a guide rail, and two clamping blocks. The base plate, top plate, guide rail, and two clamping blocks form a fixing mechanism. After the mold to be tested is placed on the surface of the top plate, the weight of the mold itself presses down on the top plate, and the top plate pushes the two clamping blocks closer together, thereby using the two clamping blocks to initially clamp and fix the mold. During the test, the testing head of the Rockwell hardness tester further presses down on the mold, which can further ensure the stability of the mold during the test. This device can quickly realize the installation and disassembly of the mold, improving the efficiency of the test.
[0013] 2. When in use, this utility model is a hardness testing device for mold production and processing. It is equipped with a lifting seat, a mounting component and a mounting sleeve. The fixing mechanism consisting of a bottom plate, a top plate, a guide rail and two clamping blocks is fixedly connected to the mounting sleeve. The mounting sleeve and the mounting component can be quickly disassembled and assembled. For molds of different sizes, the fixing mechanism of different sizes can be replaced by disassembling the mounting sleeve, thereby improving the flexibility of use. Attached Figure Description

Detailed Implementation
[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1-5 As shown, a hardness testing device for mold production and processing is disclosed, including a Rockwell hardness tester 1. A lifting base 2 is installed at the bottom of the Rockwell hardness tester 1, and a mounting component 3 is fixed at the top of the lifting base 2. A detachable mounting sleeve 4 is fixedly fitted onto the surface of the mounting component 3. A base plate 5 is fixed to the upper surface of the mounting sleeve 4, and a top plate 6 is provided above the base plate 5. A strip-shaped opening 61 is opened in the middle of the top plate 6, and two clamping blocks 8 are slidably connected inside the strip-shaped opening 61. A guide rail 7 is fixed to the upper surface of the base plate 5. The two clamping blocks 8 are designed with an inclined surface on the side away from each other, and a T-shaped groove 81 is opened at the bottom of each of the two clamping blocks 8. The T-shaped groove 81 is fitted onto the surface of the guide rail 7 and is slidably connected to the guide rail 7. The base plate 5, the top plate 6, the guide rail 7, and the two clamping blocks 8 constitute a fixing mechanism.
[0024] In this embodiment, the Rockwell hardness tester 1 adopts existing technology, and the specific model is not limited. Its specific working principle will not be described in this solution.
[0025] The Rockwell hardness tester 1 is connected to a protective door 12 via a hinge in the middle.
[0026] When conducting hardness testing, the protective door 12 can be closed to protect on-site personnel.
[0027] Multiple vertical tubes 10 are fixed to the side of the upper surface of the base plate 5, and vertical rods 11 are slidably connected inside the vertical tubes 10. The top of the vertical rods 11 is fixed to the lower surface of the top plate 6.
[0028] When the mold is placed on the upper surface of the top plate 6, the mold will press down on the top plate 6 under its own weight. Since the two clamping blocks 8 are on the opposite side of the slope, the strip opening 61 on the top plate 6 will press the slope of the clamping block 8, causing the two clamping blocks 8 to move along the guide rail 7 and move closer to each other, thereby using the two clamping blocks 8 to clamp and fix the mold.
[0029] A second spring 9 is fixed to the upper surface of the base plate 5 and the lower surface of the top plate 6. When the mold is removed from the upper surface of the top plate 6, the second spring 9 will push the top plate 6 to move upward and reset.
[0030] The inner top wall of the T-slot 81 has an inner groove 82, and a roller 83 is rotatably connected inside the inner groove 82. The bottom end of the roller 83 is in contact with the upper surface of the guide rail 7.
[0031] When the clamping block 8 moves along the surface of the guide rail 7 through the T-slot 81, the roller 83 can reduce the friction between the clamping block 8 and the guide rail 7, thereby ensuring the smooth movement of the clamping block 8.
[0032] The mounting assembly 3 includes a mounting base 31 fixed to the top of the lifting base 2, and a groove 32 is provided on the side wall of the mounting base 31. A first spring 33 is fixed on the inner side wall of the groove 32. A locking rod 34 is fixed on the other end of the first spring 33. The mounting sleeve 4 is sleeved on the surface of the mounting base 31, and a locking hole 41 is provided on the side wall of the mounting sleeve 4. The end of the locking rod 34 away from the first spring 33 is locked into the locking hole 41.
[0033] If the entire fixing mechanism needs to be replaced, first squeeze the locking rod 34 back into the groove 32, separating the locking rod 34 from the locking hole 41. Then, the mounting sleeve 4 can be removed from the surface of the mounting base 31, thereby disassembling the entire fixing mechanism. To replace another set of fixing mechanisms, after placing the mounting sleeve 4 of the other set of fixing mechanisms on the surface of the mounting base 31, the first spring 33 pushes the locking rod 34 into the locking hole 41, thereby achieving quick replacement of the fixing mechanism.
[0034] Working principle: Open the protective door 12 and place the mold on the upper surface of the top plate 6 of the fixing mechanism. Under the pressure of the mold's own weight, it will press down on the top plate 6. Since the two clamping blocks 8 are designed with a slope on the side that is far apart from each other, the strip opening 61 on the top plate 6 will press against the slope of the clamping blocks 8, causing the two clamping blocks 8 to move along the guide rail 7 and move closer to each other, thereby using the two clamping blocks 8 to clamp and fix the mold. Then close the protective door 12 and start the Rockwell hardness tester 1. When the testing head of the Rockwell hardness tester 1 descends and presses the mold for testing, it can provide further downward pressure, making the two clamping blocks 8 clamp the mold more firmly. After the test is completed, open the protective door 12 and remove the mold from the upper surface of the top plate 6.
[0035] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
