[0003] However, the existing hot pressing sintering machine has a rather complicated mold-changing process, which often requires workers to spend a lot of time and energy to operate. It is not only inefficient, but also poses certain safety hazards during operation.

[0004] Meanwhile, existing mold changing devices are not adaptable to molds of different sizes and cannot meet diverse production needs. Therefore, we propose a quick mold changing auxiliary device for hot pressing sintering machines to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a rapid mold-changing auxiliary device for hot pressing sintering machines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0028] This application discloses a quick mold changing auxiliary device for a hot pressing sintering machine.

[0029] Reference Figure 1-5 A quick mold changing auxiliary device for a hot pressing sintering machine includes a housing 101. A placement seat 105 for placing a mold base is slidably installed on the bottom inner wall of the housing 101. A fixing plate 102 is fixedly installed inside the housing 101. A hydraulic cylinder 103 is fixedly installed on the top of the fixing plate 102. A pressure head 104 for extruding the mold base is fixedly installed on the output shaft of the hydraulic cylinder 103. Two moving holes 201 are opened on the top of the placement seat 105. A sloping groove 202 is opened on the bottom inner wall of the housing 101. A moving seat 203 is slidably installed in the moving holes 201, and the bottom end of the moving seat 203 is slidably installed in the sloping groove 202. A clamping plate 303 for clamping and fixing the mold base is provided on one side of the moving seat 203. A connecting mechanism is provided between the clamping plate 303 and the moving seat 203.

[0030] In this embodiment, the connecting mechanism includes a rectangular hole 301 and a rectangular rod 302. The rectangular hole 301 is opened on one side of the movable seat 203. The rectangular rod 302 is slidably installed in the rectangular hole 301. One end of the rectangular rod 302 is fixedly installed on the corresponding clamping plate 303. A connecting plate 304 is fixedly installed on one end of the rectangular rod 302. A scale rod 305 is fixedly installed on one side of the connecting plate 304. One end of the scale rod 305 passes through the movable seat 203 and is fixedly installed on the clamping plate 303. The scale rod 305 makes it easy to intuitively understand the moving distance of the clamping plate 303, thereby more accurately adjusting the clamping of mold bases of different sizes.

[0031] In this embodiment, a bolt hole 401 is provided on the top inner wall of the rectangular hole 301. A locking bolt 402 is installed in the internal thread of the bolt hole 401, and the locking bolt 402 is adapted to the rectangular rod 302. The locking bolt 402 can be used to fix and release the rectangular rod 302, thereby adjusting the position of the clamping plate 303. This structure is simple and reliable, and can effectively ensure the stability of clamping mold bases of different sizes.

[0032] In this embodiment, the same guide rod 204 is fixedly installed on both inner walls of the moving hole 201, and the moving seat 203 is slidably sleeved on the guide rod 204. The guide rod 204 can guide the movement of the moving seat 203 and ensure its stability. Rolling balls are rolled on both sides of the guide rod 204. The rolling balls are rolledly connected to the inclined groove 202. The setting of the rolling balls can reduce the friction between the moving seat 203 and the inclined groove 202, making the moving seat 203 move more smoothly and effectively improving the efficiency and reliability of the device operation.

[0033] In this embodiment, two baffles 501 are fixedly installed on the bottom inner wall of the housing 101. A threaded rod 502 is rotatably installed on the rear side of the baffles 501. A drive seat 503 is fixedly installed on both sides of the placement seat 105, and the drive seat 503 is threaded onto the threaded rod 502. When the threaded rod 502 rotates, it can drive the placement seat 105 to move through the drive seat 503. This structure provides smooth transmission and can accurately control the moving position of the placement seat 105, ensuring the accuracy of the mold changing operation.

[0034] In this embodiment, a protective shell 601 is fixedly installed on the rear side of the housing 101. A drive shaft 602 is rotatably installed on the inner walls of both sides of the protective shell 601. A drive motor 603 is fixedly installed on one side where the shell is placed. The output shaft of the drive motor 603 is fixedly connected to the drive shaft 602. A drive mechanism is provided between the drive shaft 602 and the threaded rod 502. The protective shell 601 can protect the drive mechanism, prevent dust, debris, etc. from entering and affecting the transmission effect, and extend the service life of the device.

[0035] In this embodiment, the driving mechanism includes a driving bevel gear 604 and a driven bevel gear 605. Two driving bevel gears 604 are fixedly installed on the driving shaft 602. The rear end of the threaded rod 502 extends into the protective shell 601 and is fixedly installed with a driven bevel gear 605. The driving bevel gear 604 meshes with the corresponding driven bevel gear 605. Through the meshing transmission of the driving bevel gear 604 and the driven bevel gear 605, the driving shaft 602 drives the threaded rod 502. The bevel gear transmission has the characteristics of strong load-bearing capacity and high transmission efficiency, which can ensure the stable and reliable operation of the device.

[0036] In this embodiment, a T-shaped groove with one side open is provided on the bottom inner wall of the housing 101. A T-shaped seat that is slidably connected to the T-shaped groove is fixedly installed on the bottom of the placement seat 105. The cooperation between the T-shaped groove and the T-shaped seat can limit and guide the movement of the placement seat 105, ensuring the accuracy of the movement of the placement seat 105. At the same time, the T-shaped structure can prevent the placement seat 105 from falling off during the movement, thus improving the safety of the device.

[0037] The working principle of this utility model is as follows: When it is necessary to change the mold, the drive motor 603 is started, which drives the drive shaft 602 to rotate. The drive bevel gear 604 on the drive shaft 602 rotates accordingly, and through meshing with the driven bevel gear 605, the threaded rod 502 rotates. When the threaded rod 502 rotates, it drives the placement seat 105 to slide along the T-slot towards the outside of the housing 101 through the drive seat 503 until the placement seat 105 is completely removed from the housing 101. Under the action of the inclined groove 202, the placement seat 105 drives the moving seat 203 to move forward. The placement seat 105 moves away from the mold base along the inclined groove 202. The moving seat 203 drives the clamping plate 303 to move through the drive rod, which can release the clamping and fixing of the mold base. At this time, the worker can easily remove the old mold from the placement seat 105 and install the new mold.

[0038] After installing the new mold, the drive motor 603 is restarted, causing the placement seat 105 to slide in the reverse direction into the housing 101. During this process, due to the action of the inclined groove 202, the moving seat 203 slides along the guide rod 204 within the moving hole 201, simultaneously moving the clamping plate 303 towards the mold base to clamp it. When the mold base is of different sizes, the rectangular rod 302 can be fixed or released by rotating the locking bolt 402. The distance between the clamping seat and the mold base can be adjusted by moving the clamping plate 303. When the placement seat 105 moves into the housing 101, the clamping plate 303 contacts and presses the mold base. Finally, the hydraulic cylinder 103 is activated, and its output shaft drives the pressure head 104 downwards to press the mold base, completing the preparation work before hot pressing and sintering.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
