Description

Technical Field

[0001] This utility model relates to the field of die casting molds, and in particular to a die casting mold that can be stably exported. Background Technology

[0002] Die casting molds are tools used for pressure casting of metals and are key process equipment in the industrial manufacturing field.

[0003] When performing die casting using existing die casting molds, the mold is first installed on the die casting machine and the clamping force and locking force are adjusted. The mold is preheated to a specific temperature (e.g., 150-200°C for aluminum alloy molds) by means of electric heating, and then a release agent is evenly sprayed and dried by an automatic spraying device. Next, the metal alloy is heated and melted in a furnace to a liquid state (the melting temperature and composition are well controlled). The molten metal is then injected into the closed mold cavity through a gating system. The die casting machine applies high pressure of tens to hundreds of megapascals to quickly fill and compact the molten metal in the cavity. Subsequently, the molten metal cools and solidifies in the cavity, and the die casting machine opens the mold after forming.

[0004] In the existing die-casting mold production process, the die-cast material has burrs on the edges and corners. The material needs to be transferred from the demolding station to a special cleaning station, which is a cumbersome process, resulting in a longer production process and low efficiency. Therefore, a die-casting mold that can be stably exported is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a die-casting mold that can be stably exported, aiming to solve the problem that burr cleaning in the prior art requires transfer to a special cleaning station, which is cumbersome in terms of turnover.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a stable die-casting mold, including a die-casting platform, a die-casting machine fixedly connected to the top of the die-casting platform, a cleaning mechanism and a limiting and fixing mechanism provided on the top of the die-casting platform, the cleaning mechanism including a lower die-casting mold, the bottom of the lower die-casting mold fixedly connected to the top of the die-casting platform, a lifting block slidably connected to the inner wall of the lower die-casting mold, a hydraulic rod fixedly connected to the bottom of the die-casting platform, the top end of the inner rod of the hydraulic rod fixedly connected to the bottom of the lifting block, a rotating ring rotatably connected to the inner wall of the lifting block, a support block fixedly connected to the outer wall of the rotating ring, an electric push rod fixedly connected to the inner wall of the support block, and a cleaning scraper fixedly connected to the inner rod of the electric push rod.

[0007] As a further description of the above technical solution:

[0008] The cleaning mechanism also includes a worm gear ring, the inner wall of which is fixedly connected to the outer wall of the rotating ring.

[0009] As a further description of the above technical solution:

[0010] The cleaning mechanism also includes a motor, the outer wall of which is fixedly connected to the inner wall of the lifting block.

[0013] As a further description of the above technical solution:

[0014] The limiting and fixing mechanism includes a support rotating rod, the bottom end of which is rotatably connected to the top of the die-casting table, and the top end of which is fixedly connected to a support plate.

[0015] As a further description of the above technical solution:

[0016] The limiting and fixing mechanism also includes an electric push rod two, the bottom of which is fixedly connected to the top of the support plate.

[0017] As a further description of the above technical solution:

[0018] The limiting and fixing mechanism also includes a fixing plate, the top of which is fixedly connected to the bottom end of the inner rod of the electric push rod.

[0019] As a further description of the above technical solution:

[0020] The limiting and fixing mechanism also includes a handle, the side wall of which is fixedly connected to the side wall of the support plate.

[0023] 2. In this utility model, by setting a limiting and fixing mechanism, the fixing plate can be driven to descend vertically by an electric push rod and make close contact with the top surface of the die-cast material, thereby forming a stable limiting and fixing of the material, avoiding material shaking or displacement when cleaning burrs, and ensuring the safety and accuracy of the cleaning process.

The hydraulic rod 213 provides power for the lifting block 212 to rise. The inner wall of the lifting block 212 is rotatably connected to the rotating ring 214. The rotating ring 214 can drive the support block 215 and the cleaning scraper 217 to rotate to remove burrs. The outer wall of the rotating ring 214 is fixedly connected to the support block 215. The support block 215 is used to install the electric push rod 216 and the cleaning scraper 217. The inner wall of the support block 215 is fixedly connected to the electric push rod 216. The electric push rod 216 can push the cleaning scraper 217 to extend or retract. The inner rod of the electric push rod 216 is fixedly connected to the cleaning scraper 217. The cleaning scraper 217 is used to clean the burrs on the edges of the material.

[0032] Reference Figures 1-3 The cleaning mechanism 2 also includes a worm gear ring 218, the inner wall of which is fixedly connected to the outer wall of the rotating ring 214. The worm gear ring 218 meshes with the worm 220 to drive the rotating ring 214 to rotate. The cleaning mechanism 2 also includes a motor 219, the outer wall of which is fixedly connected to the inner wall of the lifting block 212. The motor 219 serves as a power source to drive the worm 220 to rotate. The cleaning mechanism 2 also includes a worm 220, the right end of which is fixedly connected to the output end of the motor 219. The outer wall of the worm 220 meshes with the outer wall of the worm gear ring 218. The worm 220 transmits the power of the motor 219 to the worm gear ring 218 and the rotating ring 214.

[0033] Reference Figure 1 , Figure 4The limiting and fixing mechanism 3 includes a support rotating rod 311, the bottom end of which is rotatably connected to the top of the die-casting table 1. The support rotating rod 311 can drive the support plate 312 and the fixed plate 314 to rotate and adjust their positions. The top end of the support rotating rod 311 is fixedly connected to the support plate 312, which is used to install the electric push rod 313 and the fixed plate 314. The limiting and fixing mechanism 3 also includes the electric push rod 313, the bottom of which is fixedly connected to the top of the support plate 312. The electric push rod 313 can push the fixed plate 314 down to fix the material. The limiting and fixing mechanism 3 also includes the fixed plate 314, the top of which is fixedly connected to the bottom end of the inner rod of the electric push rod 313. The fixed plate 314 is used to contact and limit the die-cast material. The limiting and fixing mechanism 3 also includes a handle 315, the side wall of which is fixedly connected to the side wall of the support plate 312. The handle 315 facilitates manual pulling of the support plate 312 to rotate and adjust its position.

[0034] Working principle: By starting the die casting machine 4, the die casting machine 4 can perform die casting molding. When it is necessary to demold the material inside the lower die casting mold 211, the hydraulic rod 213 is started, so that the top of the inner rod of the hydraulic rod 213 pushes the lifting block 212 to rise. The lifting block 212 can eject the die-cast material inside the lower die casting mold 211, so as to stably export the material from the lower die casting mold 211.

[0035] By pulling the handle 315, the support plate 312 and the support rod 311 are rotated on the top of the die-casting table 1, thereby moving the fixed plate 314 above the lower die-casting mold 211. Then, by activating the electric push rod 313, the inner rod of the electric push rod 313 pushes the fixed plate 314 to descend, so that the fixed plate 314 comes into contact with the die-cast material. The fixed plate 314 can limit and fix the die-cast material, so as to facilitate the subsequent cleaning of the burrs on the edges of the material.

[0036] After the lifting block 212 pushes the material out, the bottom of the cleaning scraper 217 is parallel to the top of the lower die-casting mold 211 to facilitate subsequent cleaning of burrs on the edges and corners. By activating the electric push rod 216, the inner rod of the electric push rod 216 pushes the cleaning scraper 217 to move. The cleaning scraper 217 can extend from inside the support block 215. Then, by activating the motor 219, the output end of the motor 219 drives the fixedly connected worm gear 220 to rotate, thereby driving the worm wheel ring 218 meshing with the outer wall of the worm gear 220 to rotate. The worm wheel ring 218 drives the rotating ring 214 fixedly connected to the inner wall to rotate. The rotating ring 214 drives the cleaning scraper 217 to rotate through the support block 215 fixedly connected to the outer wall. The cleaning scraper 217 can clean the burrs on the edges and corners of the material, thereby ensuring the quality of the material.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
