Description

Technical Field

[0001] This utility model relates to the field of casting mold technology, and in particular to a casting mold for an automotive turbocharger housing. Background Technology

[0002] A turbocharger is a device used to increase the performance of an internal combustion engine. It is usually composed of a housing and internal components. Therefore, in the production and processing of turbochargers, the housing of the turbocharger is usually cast using molds.

[0003] Most automotive turbocharger housing casting molds involve aligning and clamping the upper and lower molds during use, then pouring molten metal into the mold, waiting for the molten metal to cool and solidify, and finally separating the upper and lower molds to remove the formed housing. However, after casting and cooling, most casting molds typically require manual removal of the cast parts from the mold. This process is not only time-consuming and labor-intensive, but also inefficient due to the low efficiency of manual operation, resulting in reduced production efficiency. Therefore, it is necessary to improve the existing technology to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a casting mold for automotive turbocharger housings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-4 A casting mold for a turbocharger housing includes a base 1, a lower mold 11 fixedly connected to the top of the base 1 by bolts, a casting mold for casting the turbocharger housing is provided on the lower mold 11, and a through hole for ejecting the housing sample is provided at the center of the casting mold.

[0024] The base 1 has a cavity at the top. The four corners of the top of the lower mold 11 are welded with cylinders 9. The top of the cylinders 9 is fixed with a top plate 7 by bolts. The lower mold 11 and the top plate 7 are slidably connected to an upper mold 10 that slides along the outside of the cylinders 9. The bottom of the upper mold 10 and the top of the lower mold 11 are both provided with through holes. The top plate 7 is provided with a lifting assembly for moving the upper mold 10. The lifting assembly includes a threaded rod 6. The threaded rod 6 is rotatably connected to the top plate 7 by a bearing, and one end of the threaded rod 6 passes through the top plate 7. A handwheel 5 is welded to the top of the threaded rod 6. A slide 17 is fixedly connected to the top of the upper mold 10 and is threadedly connected to the threaded rod 6. A protrusion 19 is welded to the bottom of the threaded rod 6 and is located in the through groove at the top of the upper mold 10. The threaded rod 6 can be rotated by the handwheel 5. The protrusion 19 at the bottom of the threaded rod 6 can also push out the cooled and formed casting along the through hole of the upper mold 10.

[0025] Multiple cylinders 9 are slidably connected with sliding columns 16. The top of the sliding column 16 is fixedly connected with a limiting block 20. The outer side of the cylinder 9 is provided with a sliding groove 8, and the limiting block 20 slides in the sliding groove 8. The bottom end of the sliding column 16 passes through the lower mold 11 and is located in the cavity of the base 1. A support frame 15 is welded between the multiple sliding columns 16 at the bottom position. A column 14 is welded at the center of the top of the support frame 15, and one end of the column 14 is located in the through hole at the bottom of the lower mold 11.

[0026] In use, the upper mold 10 and the lower mold 11 are separated. The threaded rod 6 is rotated to move the upper mold 10 upward and contact the limiting block 20. The upper mold 10 is lifted and moves the limiting block 20 along the slide groove 8, thereby driving the sliding column 16 to move upward along the cylinder 9. The sliding column 16 drives the support frame 15 and the column 14 to move upward, so that the column 14 pushes out the cooled and formed casting along the through hole of the lower mold 11. Thus, the casting parts do not need to be manually removed from the mold, increasing production efficiency.

[0027] One end of the sliding column 16 is provided with an elastic component to reset the column 14. The elastic component includes a buffer spring seat 13. One end of the buffer spring seat 13 is fixedly connected to the bottom end of the sliding column 16, and the other end of the buffer spring seat 13 is fixedly connected to the inner wall of the cavity of the base 1. A buffer block is provided between the buffer spring seats 13.

[0028] When the upper mold 10 descends, the tension of the buffer spring seat 13 begins to recover, which can drive the slide column 16 and the limit block 20 at its top to retract and reset, and finally return to the initial state through the interaction between the buffer blocks.

[0029] In this utility model, two exhaust pipes 12 are provided at the top of the upper mold 10. A blocking rod 18 is slidably connected inside each of the two exhaust pipes 12. During use, the blocking rod 18 can be pulled out during the molding stage to discharge excess gas through the opening of the exhaust pipe 12. After molding is completed, the blocking rod 18 is inserted to prevent the backflow of external air from affecting the product quality.

[0030] The bottom of the upper mold 10 is provided with a through groove, and a feed pipe 3 is fixed in the through groove by bolts. The feed pipe 3 is connected to the mold cavity of the upper mold 10. A funnel 4 is welded to the top of the feed pipe 3, which allows the molten metal solution to enter the feed pipe 3 along the funnel 4. This reduces the fluctuation or splashing caused by the rapid flow of the solution, and improves the filling efficiency and product quality stability.

[0031] In particular, a fixing frame 2 is fixedly connected to the top of the base 1. A guide groove 22 is provided on one side of the fixing frame 2. An insulation sleeve 21 that wraps the feed pipe 3 is slidably connected in the guide groove 22. When in use, it can keep the feed pipe 3 warm and prevent heat loss from being too fast.

[0032] Working principle: When casting is required, the upper mold 10 and lower mold 11 are joined and pressed together by the threaded rod 6. The plug rod 18 in the vent pipe 12 is taken out. Then, the molten metal solution is introduced into the funnel 4 and enters the mold cavity of the upper mold 10 through the feed pipe 3. After the solution fills the mold cavity, the air in the mold cavity is discharged. Then, the plug rod 18 is inserted into the vent pipe 12. After the shell cools and forms, the threaded rod 6 is rotated to separate the upper mold 10 and lower mold 11. At this time, the upper mold 10 moves upward and contacts the limiting block 20, which drives the limiting block 20 to move along the slide groove 8, so that the sliding column 16 moves along the cylinder 9. The sliding column 16 drives the support frame 15 and the column 14 to move upward, so that the column 14 pushes out the cooled and formed casting along the through hole of the lower mold 11. At this time, the protrusion 19 at the bottom of the threaded rod 6 can also push out the cooled and formed casting along the through hole of the upper mold 10. Thus, the casting parts do not need to be manually removed from the mold, increasing production efficiency.

[0033] Furthermore, 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.
