Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a slag bag venting structure for a heat pump housing mold. Background Technology

[0002] In the die casting process, the slag bag is used to collect slag, inclusions and other impurities generated during the pouring of molten metal, while the venting is used to remove air from the mold cavity and gases generated during the pouring of molten metal. It is an indispensable part of the use of die casting molds.

[0003] A search revealed that patent document CN219211567U discloses a slag venting structure for a die-casting mold. This slag venting structure has a second slag bag at the convergence point of two adjacent product flow channels within the product cavity. After the mold is injected with molten metal, the liquid is drawn into the product flow channel and the second slag bag at the convergence point of the product flow channel because the pressure inside the second slag bag is lower than the pressure at the product flow channel. This accelerates the flow speed of the molten metal and achieves the venting effect.

[0004] However, the aforementioned venting structure is located inside the mold, and venting can only be completed when the molten metal flows into the mold. It cannot perform preliminary venting before the molten metal flows in, resulting in poor venting effect and thus affecting the product molding effect. Utility Model Content

[0005] In view of the problems existing in the slag bag venting structure of the heat pump housing mold, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a slag venting structure for a heat pump housing mold, which solves the problem that existing die-casting molds cannot effectively vent the gas inside the molten metal before it flows into the mold.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

The fixed mold base is provided with a liquid inlet communicating with the product cavity. A venting steel is slidably embedded inside the liquid inlet.

[0009] A snap-fit ​​positioning mechanism for limiting the venting steel is provided between the upper surfaces of the fixed mold base of the venting steel.

[0010] Preferably, the snap-fit ​​positioning mechanism includes a support rod, which is fixedly mounted on the upper surface of the fixed mold base, and two snap-fit ​​plates are rotatably sleeved on the rod wall. An annular groove is opened on the outer wall of the exhaust steel, and the snap-fit ​​plates are snap-fitted into the annular groove. Torsion springs are sleeved on both ends of the rod wall of the support rod, and the two ends of the torsion springs are fixedly connected to the support rod and the snap-fit ​​plates, respectively.

[0011] The two clamping plates are provided with a pushing mechanism at the end away from the exhaust steel for rotating and engaging the clamping plates.

[0012] Preferably, the pushing mechanism includes a pushing screw, an mounting plate is fixedly provided on the top of the fixed mold base, the pushing screw is threaded in the mounting plate, and a push plate is rotatably sleeved on one end, the push plate abuts against the two clamping plates, and a rotating block is fixedly provided on the other end of the pushing screw.

[0015] Preferably, the two card plates are arranged in a staggered, cross-shaped configuration.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model discloses a heat pump housing mold slag bag venting structure.

[0028] Example 1

[0029] This utility model provides, for example Figure 1-4 The heat pump housing mold slag bag venting structure shown includes a moving mold base 1 and a fixed mold base 2. The moving mold base 1 and the fixed mold base 2 are respectively provided with a moving mold core 3 and a fixed mold core 4 on their adjacent sides. The fixed mold core 4 is provided with a product cavity 5. Multiple first slag bags 6 and second slag bags 18 are opened on the side of the product cavity 5. A flow channel 7 is provided between two adjacent second slag bags 18. The fixed mold base 2 is provided with a liquid inlet communicating with the product cavity 5. A venting steel 8 is slidably embedded in the liquid inlet. The fixed mold base 2 is provided with two symmetrically arranged air guide holes 17. The two ends of the air guide holes 17 are respectively connected to the liquid inlet and the outside.

[0030] During the preparation of the heat pump housing mold, the moving mold base 1 and the fixed mold base 2 are closed, so that the moving mold core 3 and the fixed mold core 4 are matched. At this time, the molten metal is poured into the mold through the inlet. Before flowing into the mold, the molten metal is first vented through the venting steel 8, and the gas flows out through the venting hole 17. At this time, the gas inside the molten metal can be initially and quickly removed, reducing the venting pressure of the internal parts of the mold. Then, the molten metal enters the second slag bag 18 through the flow channel 7. The gas inside the molten metal is finally and quickly removed through the second slag bag 18, ensuring that the molten metal is stably formed inside the mold and improving the product forming quality.

[0031] In order to enable quick and stable insertion, installation, disassembly, and removal of the exhaust steel 8, such as Figure 3-4 As shown, a snap-fit ​​positioning mechanism for limiting the venting steel 8 is provided between the upper surfaces of the fixed mold base 2 and the venting steel 8. The snap-fit ​​positioning mechanism includes a support rod 9, which is fixedly installed on the upper surface of the fixed mold base 2. Two clamping plates 10 are rotatably sleeved on the rod wall. The two clamping plates 10 are arranged in an offset manner. An annular groove 11 is opened on the outer wall of the venting steel 8. The clamping plates 10 are snapped into the annular groove 11. Torsion springs 12 are sleeved on both ends of the rod wall of the support rod 9. The two ends of the torsion springs 12 are fixedly connected to the support rod 9 and the clamping plates 10 respectively.

[0032] The two clamping plates 10 are provided with a pushing mechanism at the end away from the exhaust steel 8 for rotating and engaging the clamping plates 10. The pushing mechanism includes a pushing screw 13. The top of the fixed mold base 2 is fixedly provided with a mounting plate 14. The pushing screw 13 is threaded in the mounting plate 14, and one end is rotatably sleeved with a push plate 15. The bottom of the push plate 15 contacts and engages with the upper surface of the fixed mold base 2. The push plate 15 abuts against the two clamping plates 10. The other end of the pushing screw 13 is fixedly provided with a rotating block 16.

[0033] When the mold is in use, the venting steel 8 is positioned by inserting two clamping plates 10 into the annular groove 11. At this time, the torsion spring 12 is in a torsional state. When the venting steel 8 needs to be disassembled, the rotating block 16 can be pushed, causing the pushing screw 13 to reverse and drive the push plate 15 away from the clamping plates 10. At this time, the two clamping plates 10 slowly rotate and move away from the venting steel 8 under the support of the support rod 9 and the torque recovery of the torsion spring 12, so that the venting steel 8 can be pulled out from the liquid inlet without restriction to complete the disassembly. When the venting steel 8 needs to be reinstalled, the venting steel 8 is inserted into the liquid inlet, and the screw 13 is pushed clockwise, so that the push plate 15 pushes the two clamping plates 10 and inserts the clamping plates 10 into the annular groove 11.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
