Description

Technical Field

[0001] The utility model relates to the field of processing molds, and more specifically, to a mechanical parts processing mold. Background Art

[0002] Die processing refers to the processing of forming and blanking tools. It also includes shearing dies and die-cutting dies. Usually, the die consists of an upper die and a lower die. The raw material is placed between the upper and lower dies. The raw material is formed under the action of the press (the gravity of the upper die). When the press is opened, the workpiece determined by the die shape is obtained or the corresponding waste is removed.

[0003] When performing casting processing on mechanical parts, the user places the raw materials in the lower mold and then closes the upper mold and the lower mold. After the raw materials are processed and formed, the user opens the upper mold and then takes the formed workpiece out of the lower mold. However, since the formed workpiece and the inner wall of the lower mold are generally closely attached, it is more troublesome to take out the formed workpiece.

[0004] Therefore, a mechanical parts processing mold is proposed to solve some problems existing in the above-mentioned prior art. Utility Model Content

The outer wall of the vertical plate 4 is provided with a high-temperature resistant sealing gasket matched with the base 1 and the side plate 2. The sealing gasket can effectively prevent the outflow of metal liquid. The sealing gasket is preferably FFKM perfluororubber. The outer end of the vertical plate 4 is penetrated by a driving assembly that abuts the clamping plate 3. By setting the lower mold assembly to be adjustable, it is convenient for the user to change the shape of the lower mold assembly according to actual production needs, thereby effectively improving the practicality of the lower mold assembly.

[0032] See also Figure 2 The driving assembly includes an outer driving rod 5 threadedly connected to a vertical plate 4, an inner driving rod 6 is rotatably connected inside the outer driving rod 5, and a disc 7 adapted to the force plate 11 is fixedly connected to one end of the inner driving rod 6 away from the outer driving rod 5.

[0033] See also Figure 3 The upper and lower inner walls of the through opening 9 are fixedly connected with a positioning rod 13, and the outer end of the driving block 10 is provided with a positioning groove 14 adapted to the positioning rod 13. The positioning rod 13 and the positioning groove 14 cooperate with each other to realize the positioning of the driving block 10 and avoid position displacement during the movement of the driving block 10.

[0034] See also Figure 1 The outer wall of the upper mold assembly 15 is slidably connected with a clamping block 16, and the outer end of the L-shaped rod is provided with a slot adapted to the clamping block 16. The user clamps the clamping block 16 in the slot to fix the position of the upper mold assembly, thereby making it convenient for the user to place raw materials and take out the formed workpiece.

[0035] Example 2

[0036] The utility model provides a mechanical parts processing mold, wherein the components identical or corresponding to those in embodiment 1 are marked with the corresponding reference numerals in embodiment 1. For the sake of simplicity, only the differences from embodiment 1 are described below. Figure 4 The side walls of the supporting block 8 and the driving block 10 close to each other are inclined, and the contact surfaces of the supporting block 8 and the driving block 10 are inclined, which can effectively reduce the friction between the supporting block 8 and the driving block 10, thereby facilitating the upward movement of the supporting block 8 under force to achieve the extrusion of the workpiece. Multiple extrusion blocks 12 are evenly distributed at the corners of the upper end of the supporting block 8, and the top of the supporting block 8 is at the same height as the upper surface of the base 1, which effectively improves the stability of the workpiece during extrusion.

[0037] Working principle: The user first rotates the outer drive rod 5 to adjust the position of the clamping plate 3 between the two side plates 2 according to production requirements, and then pours the liquid metal raw material into the space formed between the side plate 2 and the clamping plate 3, and then moves the upper mold assembly 15 to press it to the upper end of the lower mold assembly. After the liquid metal cools to form solid metal, the mechanical parts are completed. The casting is completed. At this time, the user moves the upper mold assembly 15 upward, and then rotates the inner drive rod 6 to move toward the clamping plate 3. After the disc 7 at the outer end of the inner drive rod 6 contacts the force plate 11, the user continues to rotate the inner drive rod 6 to move. At this time, the supporting block 8 will drive the multiple extrusion blocks 12 at its upper end under the extrusion of the driving block 10 to extrude the molded mechanical parts from the lower mold assembly, thereby facilitating the user to take out the molded mechanical parts and improve work efficiency.

[0038] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
