Description

Technical Field

[0001] This utility model relates to the field of moving scroll plate processing technology, specifically to a die-casting molding equipment for scroll plate processing. Background Technology

[0002] As a key component of core equipment such as scroll compressors and vacuum pumps, the moving scroll plate plays an irreplaceable role in numerous fields including refrigeration, air conditioning, automotive engineering, and aerospace. Die casting, as a highly efficient molding process, is well-suited for machining moving scroll plates. Die casting enables high-precision part manufacturing; by optimizing die casting process parameters and mold design, the size and shape of the moving scroll plate can be precisely controlled, reducing subsequent machining and improving production efficiency. To accelerate cooling and molding, some existing die casting equipment uses cooling components to assist in cooling, typically by circulating cooling water through pipes. However, over time, scale accumulates on the inner walls of the cooling components' pipes, making cleaning difficult and affecting cooling and molding efficiency.

[0003] Therefore, it is necessary to invent a die-casting molding equipment for vortex disk processing to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a die-casting molding equipment for vortex disk processing to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a die-casting molding equipment for vortex processing, comprising a base, a die-casting lower mold installed on the top of the base, a molding cavity opened in the middle of the top of the die-casting lower mold, an annular stacking groove opened on the top of the die-casting lower mold, an annular receiving groove opened at the bottom of the annular stacking groove, the annular stacking groove and the annular receiving groove surrounding the outside of the molding cavity, a cooling coil placed inside the annular receiving groove, and an annular cover plate placed inside the annular stacking groove.

[0006] With the design of the annular stacking groove and the annular receiving groove, the cooling coil can be placed or removed directly. Combined with the detachable structure of the annular cover plate, the cooling coil can be quickly replaced without disassembling the mold body, which significantly reduces maintenance difficulty and time cost.

[0007] Preferably, a locking fastener is installed on the front and back of the die-casting lower mold, and a locking movable component is installed on the front and back of the annular cover plate, with the two locking movable components engaging with the two locking fasteners respectively.

[0008] The coordinated design of the locking movable part and the locking fixed part enables the rapid fixing and separation of the annular cover plate and the die-casting lower mold.

[0009] Preferably, the lower die of the die casting mold is provided with an inlet pipe interface and an outlet pipe interface on the left side, and the outlet pipe interface is located above the inlet pipe interface.

[0010] The inlet pipe interface is located below the outlet pipe interface, allowing the cooling water to flow from bottom to top when it enters the cooling coil, thus filling the cooling coil completely.

[0011] Preferably, the output end of the water inlet pipe extends into the annular receiving groove and is threadedly connected to the input end of the cooling coil, and the input end of the water outlet pipe extends into the annular receiving groove and is threadedly connected to the output end of the cooling coil.

[0012] The threaded connection allows for quick assembly and disassembly of the cooling coil with the inlet and outlet water pipe interfaces without the need for special tools, thus shortening maintenance time.

[0013] Preferably, a support frame is installed on the top of the base, and a die-casting upper mold is provided below the support frame. The die-casting upper mold is located directly above the die-casting lower mold. A gate is installed on the top of the die-casting upper mold, and a die-casting core is fixedly connected to the bottom of the die-casting upper mold. The die-casting core matches the molding cavity.

[0014] After the upper die casting mold and the lower die casting mold are closed, the die casting core is inserted into the forming cavity. Molten metal is injected into the gap between the die casting core and the forming cavity through the gate. After the molten metal cools and solidifies, the moving scroll die casting part can be obtained.

[0015] Preferably, each of the four corners of the die-casting lower mold is fixedly connected to a guide slide rod, and the top ends of the four guide slide rods are fixedly connected to the inner top surface of the support frame. Each of the four corners of the die-casting upper mold is equipped with a sliding sleeve, and the four sliding sleeves are slidably connected to the four guide slide rods respectively.

[0016] The sliding fit between the guide rod and the sliding sleeve ensures that the die-casting upper mold is pressed down vertically, preventing displacement during mold closing.

[0017] Preferably, two symmetrically arranged electric push rods are installed on the top of the support frame, and the working ends of the two electric push rods extend to the bottom of the support frame and are fixedly connected to the top of the die-casting upper mold.

[0018] The die-casting upper mold is raised and lowered by an electric push rod, which facilitates the automation of mold closing and opening operations.

[0019] Preferably, a controller is installed on the front of the base, and both electric push rods are electrically connected to the controller, which can control the two electric push rods to operate synchronously.

[0020] The controller synchronizes the movement of two electric push rods to avoid mold damage or product defects caused by uneven pressure.

[0021] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0022] 1. By designing an annular stacking groove and an annular receiving groove structure on the top of the die-casting lower mold, the cooling coil can be directly placed in the annular receiving groove. With the detachable design of the annular cover plate, the cooling coil can be removed and replaced simply by removing the annular cover plate, which is convenient for regular cleaning and thus ensures the cooling and shaping efficiency of the equipment.

[0023] 2. An annular receiving groove surrounds the outside of the forming cavity. A cooling coil is installed inside the annular receiving groove. When cooling water passes through the cooling coil, it can absorb and carry away the heat from the molten metal, thereby accelerating the solidification of the molten metal and improving the cooling and shaping efficiency.

[0036] In one aspect of this embodiment, a locking fastener 7 is installed on both the front and back of the die-casting lower mold 2, and a locking movable part 8 is installed on both the front and back of the annular cover plate 6. The two locking movable parts 8 are respectively engaged with the two locking fasteners 7. A water inlet pipe interface 9 and a water outlet pipe interface 10 are provided on the left side of the die-casting lower mold 2. The water outlet pipe interface 10 is located above the water inlet pipe interface 9. The output end of the water inlet pipe interface 9 extends into the annular receiving groove 4 and is threadedly connected to the input end of the cooling coil 5. The input end of the water outlet pipe interface 10 extends into the annular receiving groove 4 and is threadedly connected to the output end of the cooling coil 5. A support frame 11 is installed on the top of the base 1. A die-casting upper mold 12 is provided below the support frame 11. The die-casting upper mold 12 is located directly above the die-casting lower mold 2. A gate 13 is installed at the top. A die-casting core 14 is fixedly connected to the bottom of the die-casting upper mold 12. The die-casting core 14 matches the forming cavity 3. A guide slide rod 15 is fixedly connected to each of the four corners of the top of the die-casting lower mold 2. The top ends of the four guide slide rods 15 are fixedly connected to the inner top surface of the support frame 11. A sliding sleeve 16 is installed at each of the four corners of the die-casting upper mold 12. The four sliding sleeves 16 are slidably connected to the four guide slide rods 15 respectively. Two symmetrically arranged electric push rods 17 are installed at the top of the support frame 11.

[0037] The cooling coil 5, electric push rod 17 and controller 18 mentioned above are all existing technology products, and their specific structures and functions will not be described in detail here.

[0038] Working principle of this utility model:

[0039] Refer to the instruction manual appendix Figure 1-8When using this utility model, firstly, the controller 18 synchronously drives the two electric push rods 17 to press down, so that the die-casting upper mold 12 and the die-casting lower mold 2 are closed under the guidance of the guide slide rod 15. The molten metal is injected into the die-casting upper mold 12 from the gate 13, so that the molten metal fills the gap between the die-casting core 14 and the forming cavity 3. After the pouring is completed, it is left to stand and hold pressure for a period of time.

[0040] After the pressure holding is completed, the water inlet pipe interface 9 and the water outlet pipe interface 10 are connected to the external circulating cooling water system. Cooling water is continuously supplied to the cooling coil 5 through the external circulating cooling water system.

[0041] After the equipment has been used for a period of time, the cooling coil 5 inside the equipment needs to be removed, replaced and cleaned. First, loosen the locking movable part 8 and the locking fixed part 7, remove the annular cover plate 6 to expose the cooling coil 5 in the annular receiving groove 4. Then, unscrew the water inlet pipe interface 9 and the water outlet pipe interface 10. After that, the old cooling coil 5 with scale attached can be removed.

[0042] Then, place the new cooling coil 5 into the annular receiving groove 4, then screw on the water inlet pipe interface 9 and the water outlet pipe interface 10. Finally, place the annular cover plate 6 back into the annular mounting groove, and fasten the locking movable part 8 and the locking fixing part 7 to restore the equipment's sealing.
