Description

Technical Field

[0001] This utility model relates to the field of die casting processing technology, specifically a fixing fixture for die casting processing. Background Technology

[0002] Die casting uses non-ferrous metals such as copper, zinc, aluminum, and magnesium or their alloys as raw materials. After melting them into a liquid state at high temperature, the liquid is injected into a pre-designed metal mold cavity under high pressure. After cooling and solidification, metal parts with the required shape, size, and performance are obtained directly. This process combines high-pressure forming with mold constraints, enabling one-time forming of complex structures. It is widely used in the automotive, electronics, and automation equipment industries.

[0003] Traditional die-casting fixtures mainly consist of a base plate and side plates, a clamping module, and a drive module. The base plate and side plates serve as the basic support structure, providing overall stability. The clamping module includes a fixed clamping plate and a sliding clamping plate. The fixed clamping plate is fixed to the base plate and serves as a support reference on one side. The sliding clamping plate moves in a directional manner through a guide rod, working in conjunction with the fixed clamping plate to complete the clamping action. The drive module is a telescopic cylinder that provides clamping power to push the sliding clamping plate closer to or away from the fixed clamping plate. Its working principle is as follows: using the parallel planes of the fixed clamping plate and the sliding clamping plate as a reference, the degree of freedom of the die-casting is restricted. The telescopic cylinder pushes the sliding clamping plate to move, reducing the distance between it and the fixed clamping plate, thereby clamping and fixing the die-casting.

[0004] However, traditional die-casting fixtures have some shortcomings in practical use. For example, the clamping force of traditional die-casting fixtures is not easy to adjust flexibly, making it difficult to meet the processing needs of die-castings of different sizes and shapes.

[0009] Preferably, an operating handle is fixedly connected to the side of the rotating disk away from the bidirectional threaded rod, and a spring is sleeved on the outer wall of the bidirectional threaded rod, with one end of the spring abutting against the outer wall of the threaded sleeve.

[0010] Preferably, the clamping assembly includes a slide block slidably connected to the outer wall of the bidirectional threaded rod, the end of the spring away from the threaded sleeve abutting against the outer wall of the slide block, and a sliding groove extending through the outer wall of the slide block, the inner wall of the sliding groove being slidably connected to the outer wall of the bidirectional threaded rod.

[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, not all, embodiments of this utility model, 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.

[0017] Please see Figures 1-4 The present invention provides the following two preferred embodiments: Example 1: A fixing fixture for die casting processing includes a base plate 1. A set of fixing plates 2 are fixedly connected to both sides of the base plate 1, and the two sets of fixing plates 2 are symmetrically arranged. A fixing slot is formed through the upper surface of the fixing plate 2. Through the fixing slot, the device can be securely installed on the die casting processing workbench using bolts or other fasteners, ensuring the stability of the device during operation. A mounting plate 3 is fixedly connected to the upper surface of the base plate 1. A mounting groove is formed through the outer surface of the mounting plate 3. A fixing bearing 4 is fixedly connected to the inner wall of the mounting groove. A bidirectional threaded rod 10 is fixedly connected to the inner ring of the fixing bearing 4. A clamping assembly 5 is slidably connected to the outer wall of the bidirectional threaded rod 10. The upper surface of the base plate 1... Mounting plate 2 6 is fixedly connected to the mounting plate 2 6. Mounting groove 2 is opened through the outer surface of mounting plate 2 6. Fixed bearing 2 7 is fixedly connected to the inner wall of mounting groove 2. The inner ring of fixed bearing 2 7 is fixedly connected to the end of bidirectional threaded rod 10 away from fixed bearing 4. Guide rod 9 is fixedly connected between mounting plate 1 3 and mounting plate 2 6. Threaded sleeves 8 are threaded to both ends of bidirectional threaded rod 10. Rotating disk 11 is fixedly connected to the end of bidirectional threaded rod 10 near fixed bearing 4. Operating handle is fixedly connected to the side of rotating disk 11 away from bidirectional threaded rod 10 to facilitate the operator to rotate rotating disk 11. Spring 12 is sleeved on the outer wall of bidirectional threaded rod 10. One end of spring 12 abuts against the outer wall of threaded sleeve 8.

[0018] In actual use, fasteners such as bolts are used to securely install the fixing fixture on the die-casting workbench through the fixing slot on the fixing plate 2. When clamping and fixing the die-casting, the die-casting is placed between the two clamping plates 504. At this time, the two springs 12 will drive the two slides 501 to move towards the middle, so that the two clamping plates 504 initially clamp and fix the die-casting. If it is necessary to further adjust the clamping degree of the clamping assembly 5 on the die-casting, the operator can rotate the rotating disk 11 through the operating handle. The rotating disk 11 drives the bidirectional threaded rod 10 to rotate. Since both ends of the bidirectional threaded rod 10 are threaded with threaded sleeves 8, and the slides 501 are slidably connected to the guide rod 9 through the guide groove 502, the rotation of the bidirectional threaded rod 10 will drive the two threaded sleeves 8 to move, adjust the compression of the springs 12, and achieve precise adjustment of the clamping degree of the die-casting.

[0019] Example 2: The clamping assembly 5 includes a slide block 501 slidably connected to the outer wall of the bidirectional threaded rod 10. The end of the spring 12 away from the threaded sleeve 8 abuts against the outer wall of the slide block 501. A sliding groove 505 is formed through the outer wall of the slide block 501, and the inner wall of the sliding groove 505 is slidably connected to the outer wall of the bidirectional threaded rod 10. A guide groove 502 is formed through the outer wall of the slide block 501, and the inner wall of the guide groove 502 is slidably connected to the outer wall of the guide rod 9. A clamping plate 504 is fixedly connected to the upper surface of the slide block 501. An adhesive layer 507 is provided on the outer wall of the holding plate 504; a polyurethane rubber pad 506 is fixedly connected to the holding plate 504 through the adhesive layer 507. The polyurethane rubber pad 506 can provide cushioning protection for the die-casting and prevent damage to the surface of the die-casting during the clamping process. A support inclined plate 503 is fixedly connected to the side of the holding plate 504 away from the polyurethane rubber pad 506. The side of the support inclined plate 503 away from the holding plate 504 is fixedly connected to the upper surface of the slide block 501 to enhance the stability of the holding plate 504.

[0020] In actual use, after die casting is completed, the operator rotates the rotating disk 11 in the opposite direction to move the two clamping plates 504 away from each other, and the die casting can be easily removed. When it is necessary to replace the polyurethane rubber pad 506, the operator can apply a certain external force to overcome the adhesion of the adhesive layer 507, remove the old polyurethane rubber pad 506 from the clamping plate 504, and then fix the new polyurethane rubber pad 506 to the clamping plate 504 through the adhesive layer 507.

[0021] 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.
