Description

Technical Field

[0001] The utility model relates to the field of molds, and specifically relates to a multi-stage parting mold for a clutch housing. Background Art

[0002] The structure of the clutch housing is relatively complex and large in volume. Its structure includes many hole-shaped structures for connection. During the parting process of these hole-shaped structures, the pressing force between the hole-forming needle for forming the hole-shaped structure and the hole-shaped structure is large, and often a large additional driving force is required to complete the parting operation. In the conventional single-stage longitudinal parting operation, while parting between the hole-shaped structure and the hole-forming needle is completed, parting between the upper mold and the formed clutch housing also needs to be completed. However, the pressing force required for parting between the upper mold and the clutch housing is small, that is, the requirement for additional driving force is low, resulting in waste of the parting driving force during the single-stage parting process, greater energy consumption, higher cost, and being unfavorable for controlling the production cost and efficient production of the clutch housing. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a multi-stage parting mold for a clutch housing that adopts longitudinal multi-stage parting, first parts between the hole-shaped structure and the hole-forming needle, and then parts between the upper mold and the clutch housing to reduce the additional driving force and avoid waste of the additional driving force.

[0004] The technical solution adopted by the utility model to solve the above problems is: a multi-stage parting mold for a clutch housing, including a body. The body includes a top plate, an upper mold base, a lower mold base, and a base from top to bottom. The lower mold base is fixedly connected to the base. There are multiple multi-stage parting components connected between the top plate, the upper mold base, and the lower mold base. The multiple multi-stage parting components are used to drive the upper mold base to separate from the lower mold base after the top plate moves a certain distance away from the upper mold base when driving the top plate away from the upper mold base. A hole-forming needle for forming the hole-shaped structure on the clutch housing is fixedly connected to the top plate. The upper mold base and the lower mold base are used to form the main structure of the clutch housing. There are a total of four multi-stage parting components on the body, and the four multi-stage parting components are evenly arranged along the circumference of the body.

[0005] Compared with the prior art, the advantages of the present utility model are as follows: during die splitting, the top plate moves first and drives the hole-forming needle to move upward, so that the hole-forming needle is separated from the hole-shaped structure first. At this time, only the gravity of the top plate and the pressing force between the hole-forming needle and the hole-shaped structure need to be overcome. Then the top plate continues to move upward, driving the upper die on the upper die base to separate from the clutch housing. At this time, only the gravity of the top plate, the gravity of the upper die base, and the pressing force between the upper die and the clutch housing need to be overcome. Among them, the driving force to overcome the gravity of the upper die base is much greater than the pressing force between the hole-forming needle and the hole-shaped structure. Therefore, during die splitting, the maximum driving force is the sum of the gravity of the top plate, the gravity of the upper die base, and the pressing force between the upper die and the clutch housing. For a conventional single-stage die-splitting mold, it is necessary to overcome the gravity of the top plate, the gravity of the upper die base, the pressing force between the upper die and the clutch housing, and the pressing force between the hole-forming needle and the hole-shaped structure at the same time, resulting in greater energy consumption and waste of driving force. The design of the four multi-stage die-splitting components is because the mold has a large volume. The four multi-stage die-splitting components can ensure the unity of each area and the even distribution of forces during the die-splitting process of the mold, ensuring the stability of the die-splitting process.

[0006] As an improvement of the present utility model, installation inclined surfaces for installing multi-stage die-splitting components are provided at the four corners of the top plate, the upper die base, and the lower die base. Through this improvement, the firmness and stability of the installation of the multi-stage die-splitting components are ensured, and at the same time, the structure of the multi-stage die-splitting components can be simplified, avoiding the need for bending connection design.

[0007] As an improvement of the present utility model, the multi-stage die-splitting component includes a driving connection plate, a rotating connection plate, and a locking block. The driving connection plate is arranged along the height direction, and one end of the driving connection plate is fixedly connected to the top plate. The rotating connection plate is rotatably connected to the upper die base, and the locking block is fixedly connected to the lower die base. An inclined block is provided at one end of the rotating connection plate close to the top plate. The inclined block is arranged on the side of the rotating connection plate close to the driving connection plate, and the inclined surface of the inclined block is arranged on the side close to the upper die base. A driving block is provided on the side of the driving connection plate close to the rotating connection plate. The upward side of the driving block is provided with a driving surface that fits the inclined surface of the inclined block. In the closed-die state, there is a height difference between the driving block and the inclined block. Through this improvement, after the top plate moves a certain distance, the movement of the driving connection plate drives the rotating connection plate to rotate, so as to release the lock between the upper die base and the lower die base, ensuring the smoothness of die splitting of the upper die base.

[0008] As an improvement of the present utility model, one end of the rotating connecting plate close to the lower die base is provided with a hook block for engaging with the locking block. In the mold closing state, the hook block engages with the locking block. During the mold opening process, after the rotating connecting plate rotates, the hook block separates from the locking block. Through this improvement, when starting to separate the molds, it can be ensured that the movement of the top plate will not drive the upper die base to rise, so as to avoid the situation of the upper die base rising prematurely and then falling, and ensure the safe use of the mold.

[0009] As an improvement of the present utility model, a reset ejector pin is provided on the side of the rotating connecting plate away from the driving connecting plate. The reset ejector pin is arranged on the side of the rotating connection of the rotating connecting plate away from the hook block. The reset ejector pin is used to reset the rotating connecting plate after it is rotated by the driven connecting plate. Through this improvement, not only can the rotated rotating connecting plate be reset, but also the excessive rotation of the rotating connecting plate can be avoided, limiting the rotation angle of the rotating connecting plate within a certain range and avoiding interference with other structures.

[0010] As an improvement of the present utility model, the reset ejector pin is movably connected in an installation groove. The installation groove is fixedly connected to the upper die base. A reset spring is arranged in the installation groove. The reset spring is sleeved on the reset ejector pin. One end of the reset spring abuts against the installation groove, and the other end of the reset spring abuts against the reset ejector pin. Through this improvement, the installation of the reset ejector pin is realized.

[0011] As an improvement of the present utility model, the abutting end of the reset ejector pin and the rotating connecting plate is hemispherical. Through this improvement, the abutting part between the rotating connecting plate and the reset ejector pin is protected, reducing the degree of damage.

[0012] As an improvement of the present utility model, the abutting part between the rotating connecting plate and the reset ejector pin is arc-shaped. Through this improvement, when the rotating connecting plate is abutted by the reset ejector pin, the radiality of the abutting force is ensured, avoiding too large an inclined stress angle and further avoiding deformation of the reset ejector pin.

[0013] As an improvement of the present utility model, a driving block is fixedly connected to one end of the driving connecting plate close to the lower die base. A synchronous moving abutting block is fixedly connected to the upper die base. During mold closing, there is a height difference between the driving block and the synchronous moving abutting block, and the height difference between the driving block and the synchronous moving abutting block is greater than the height difference between the driving block and the inclined block. During mold opening, the driving block moves upward a certain distance to abut against the synchronous moving abutting block to drive the upper die base to rise synchronously. Through this improvement, after the driving connecting plate moves a certain distance and ensures the release of the engagement between the upper die base and the lower die base, the upper die base can be driven to move synchronously.

[0014] As an improvement of the utility model, a limiting groove is provided on the installation inclined surface, the driving block is movably connected in the limiting groove, and the synchronous moving abutting block is arranged in the limiting groove. Through the improvement, the stability and accuracy of the abutting connection between the driving block and the synchronous moving abutting block are ensured, and the driving effect of the driving block driving the synchronous moving abutting block to perform synchronous movement is ensured.

Detailed Description of the Preferred Embodiment

[0021] The embodiments of the present utility model will be further described below with reference to the accompanying drawings.

[0022] Such as Figures 1-3As shown in the figure, a multi-stage die-casting mold for a clutch housing 8 includes a main body, which from top to bottom includes a top plate 1, an upper die holder 2, a lower die holder 3, and a base 4.

The multi-stage die-separating components 5 are used to drive the upper die holder 2 to separate from the lower die holder 3 after driving the top plate 1 to move a certain distance away from the upper die holder 2. A hole-forming needle 6 for forming the hole-shaped structure 8.1 on the clutch housing 8 is fixedly connected to the top plate 1. The upper die holder 2 and the lower die holder 3 are used to form the main structure of the clutch housing 8.

Among them, the side die 9.1 needs to be separated after the upper die 2.1 and the lower die 3.1 are separated, and is driven by a driving cylinder provided on the side for die separation.

[0024] As Figure 3 shown, the structure of the clutch housing 8 is complex, and the number of hole-shaped structures 8.1 is relatively large, so the pressing force that needs to be overcome during the die-separation process is relatively large.

[0025] As Figure 1 、 Figure 4As shown, the multi-stage split mold assembly 5 includes a driving connection plate 5.1, a rotating connection plate 5.2, and a locking block 5.3. The driving connection plate 5.1 is arranged along the height direction, and one end of the driving connection plate 5.1 is fixedly connected to the top plate 1. The rotating connection plate 5.2 is rotatably connected to the upper mold base 2, and the locking block 5.3 is fixedly connected to the lower mold base 3. One end of the rotating connection plate 5.2 close to the top plate 1 is provided with an inclined block 5.2.1. The inclined block 5.2.1 is arranged on the side of the rotating connection plate 5.2 close to the driving connection plate 5.1, and the inclined surface 5.2.2 of the inclined block 5.2.1 is arranged on the side close to the upper mold base 2. One side of the driving connection plate 5.1 close to the rotating connection plate 5.2 is provided with a driving block 5.1.1. The upward side of the driving block 5.1.1 is provided with a driving surface 5.1.2 that fits with the inclined surface 5.2.2 of the inclined block 5.2.1. In the mold closing state, there is a height difference between the driving block 5.1.1 and the inclined block 5.2.1. One end of the rotating connection plate 5.2 close to the lower mold base 3 is provided with a hook block 5.2.3 for engaging with the locking block 5.3. In the mold closing state, the hook block 5.2.3 engages with the locking block 5.3. During the mold opening process, after the rotating connection plate 5.2 rotates, the hook block 5.2.3 is separated from the locking block 5.3. On the side of the rotating connection plate 5.2 away from the driving connection plate 5.1, there is a reset ejector pin 5.4. The reset ejector pin 5.4 is arranged on the side of the rotating connection of the rotating connection plate 5.2 away from the hook block 5.2.3. The reset ejector pin 5.4 is used to reset the rotating connection plate 5.2 rotated by the driving connection plate 5.1. The reset ejector pin 5.4 is movably connected in an installation groove 5.5. The installation groove 5.5 is fixedly connected to the upper mold base 2. A reset spring 5.6 is arranged in the installation groove 5.5. The reset spring 5.6 is sleeved on the reset ejector pin 5.4. One end of the reset spring 5.6 abuts against the installation groove 5.5, and the other end of the reset spring 5.6 abuts against the reset ejector pin 5.4. The abutting end of the reset ejector pin 5.4 and the rotating connection plate 5.2 is hemispherical, and the abutting part of the rotating connection plate 5.2 and the reset ejector pin 5.4 is arc-shaped.

[0026] As Figure 5As shown, one end of the driving connecting plate 5.1 close to the lower die base 3 is fixedly connected with a driving block 5.1.3. A synchronous moving abutting block 5.7 is fixedly connected to the upper die base 2. When the die is closed, there is a height difference between the driving block 5.1.3 and the synchronous moving abutting block 5.7, and the height difference between the driving block 5.1.3 and the synchronous moving abutting block 5.7 is greater than the height difference between the driving block 5.1.1 and the inclined block 5.2.1. When the die is opened, the driving block 5.1.3 moves upward by a certain distance to abut against the synchronous moving abutting block 5.7 to drive the upper die base 2 to rise synchronously. A limiting groove 7.1 is provided on the installation inclined surface 7. The driving block 5.1.3 is movably connected in the limiting groove 7.1, and the synchronous moving abutting block 5.7 is arranged in the limiting groove 7.1. A replaceable block with a detachable connection is adopted at the abutting joint of the synchronous moving abutting block 5.7 and the driving block 5.1.3. After long-term use, if the synchronous moving abutting block 5.7 needs to be maintained, only the replaceable block needs to be replaced.

[0027] Through the design of this mold, the driving force required to overcome the pressing force between the forming needle 6 and the hole structure 8.1 is reduced, thereby reducing energy consumption and lowering production costs.
