Description

Technical Field

[0001] The utility model relates to the field of molds, and specifically relates to a clutch housing mold. 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 mold splitting process, the pressing force between the hole-forming needles for forming the hole-shaped structures and the hole-shaped structures is large, and often a large additional driving force is required to complete the mold splitting operation. In the conventional single-stage longitudinal mold splitting operation, while splitting the mold between the hole-shaped structures and the hole-forming needles, it is also necessary to complete the mold splitting between the upper mold and the formed clutch housing. However, the pressing force required for splitting the mold between the upper mold and the clutch housing is small, that is, the requirement for additional driving force is low, resulting in waste of mold splitting driving force, greater energy consumption and higher cost during the single-stage mold splitting process, which is not conducive to controlling the production cost and efficient production of the clutch housing. Therefore, a segmented mold splitting method is adopted to reduce energy consumption and production cost.

[0003] Also because the structure of the clutch housing is relatively complex and large in volume, it requires more injection runners, and the length of the injection runners is relatively long. When opening the mold, it is necessary to add a release agent to the injection runners to better complete the demolding of the injection runners. The traditional release agent is sprayed manually, with low efficiency, and the injection runners belong to unconventional areas and are easily forgotten, which is not conducive to the stable spraying of the injection runners. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a clutch housing mold with a release agent spraying device for the injection runners.

[0005] The technical solution adopted by the utility model to solve the above problems is: a clutch housing mold, including a body. The body includes a top plate, an upper mold base, and a lower mold base from top to bottom. A mold cavity for forming the clutch housing is provided between the upper mold base and the lower mold base. Multiple segmented mold splitting components are connected between the top plate, the upper mold base, and the lower mold base. The multiple segmented mold splitting components adopt a multi-segment mold splitting method of first separating the top plate from the upper mold base and then separating the upper mold base from the lower mold base during mold splitting. A feed runner for introducing die-casting molding materials into the mold cavity is provided on the body, and an injection component for injecting a release agent into the feed runner is further provided on the side of the body. The injection component is arranged between the top plate and the upper mold base, and the injection component performs the spraying operation of the release agent after the body is closed and before the die-casting molding materials are injected into the feed runner.

[0006] Compared with the prior art, the advantages of the present utility model are as follows: Through the design of the multi-stage die splitting assembly, the purpose of multi-stage die splitting during die splitting is achieved. Through the design of the injection assembly, the release agent can be sprayed into the injection runner through the injection assembly, without the need to separate the top plate and the upper die base by a large distance to meet the need of manual spraying, and there is no need to worry too much about the spraying state of the release agent. It only needs to complete the injection work of the injection assembly before injection, and this process can be completely incorporated into the die-casting program of the mold for periodic spraying according to the demand of the release agent. At the same time, the injection assembly is arranged between the top plate and the upper die base, which is convenient for the installation and setting of the injection assembly, and is convenient for observing the installation effect of the injection assembly to ensure the accuracy of the injection position of the injection assembly.

[0007] As an improvement of the present utility model, the injection assembly includes an injection needle, and the injection needle is fixedly connected to a driving plate. One end of the driving plate away from the injection needle is provided with a driving cylinder for driving the driving plate to move along the radial direction of the body. Through this improvement, the movement of the injection needle is realized. When the release agent needs to be sprayed, the injection needle moves towards the injection runner and sprays the release agent. When the release agent does not need to be sprayed, the injection needle moves away from the injection runner to avoid affecting the smooth flow of the die-casting molding material in the injection runner.

[0008] As an improvement of the present utility model, the injection runner includes multiple shunt runners for splitting the die-casting molding material. The injection assembly includes multiple injection needles corresponding to the multiple shunt runners one by one. An injection runner for delivering the release agent to the multiple injection needles is arranged in the driving plate. The output end of the injection runner is provided with a spraying hole, and the spraying hole is arranged on the injection needle. The input end of the injection runner is connected with a liquid storage pump, and the liquid storage pump is used for storing the release agent. Through this improvement, because the clutch housing has a relatively complex structure and a large volume, during the injection process, multiple shunt runners need to inject materials synchronously to better ensure the uniformity of the die-casting molding material injected into the mold cavity. The design of the injection needles corresponding to the multiple shunt runners one by one can ensure the integrity of the release agent spraying for the multiple shunt runners, and the design of the liquid storage pump can facilitate the storage of the release agent on the mold, without the need to add the release agent every time the release agent needs to be sprayed, making the spraying work of the release agent more convenient.

[0009] As an improvement of the present utility model, the injection material flow channel is formed by splicing a flow dividing seat and a shaping seat. The flow dividing seat is used for shaping the flow channel. The lower end of the injection material flow channel is arranged on the flow dividing seat, and the upper end of the injection material flow channel is arranged on the shaping seat. A flow limiting block is arranged at one end of the flow dividing seat close to the injection component. The injection needle penetrates through the flow limiting block to inject the release agent into the injection material flow channel. The spraying hole is arranged on the side of the injection needle. The diameter of the injection needle is equal to the diameter of the through hole on the flow limiting block through which the injection needle penetrates. Through the above improvement, the formation of the injection material flow channel is realized. Because of the design of the flow dividing channel, the die-casting molding material formed in the flow dividing channel also needs to be demolded. At this time, the injection needle can act as a thimble in the flow dividing channel for demolding. The spraying hole is arranged on the side of the injection needle to prevent the die-casting molding material from being injected into the injection needle during material injection. The design that the diameter of the injection needle is equal to the diameter of the through hole is to ensure the integrity of the flow dividing channel, which is the same as the design principle of the thimble in the traditional mold cavity.

[0010] As an improvement of the present utility model, the flow dividing seat is fixedly connected to the upper mold base, and the shaping seat is fixedly connected to the top plate. A positioning insert block is also fixedly connected to the top plate. The positioning insert block is arranged between the flow limiting block and the driving plate. One end of the positioning insert block close to the flow limiting block fits with the flow limiting block. During mold closing or mold opening, the positioning insert block moves longitudinally along the flow limiting block. Through the above improvement, through the movement positioning of the positioning insert block and the flow limiting block, the stability of the relative position during the mold closing movement process and the mold opening movement process between the top plate and the upper mold base can be ensured. At the same time, the alignment accuracy of the flow dividing seat and the shaping seat after separation and then splicing can be ensured, and the splicing and forming quality of the injection material flow channel can be guaranteed.

[0011] As an improvement of the present utility model, a positioning hole for the injection needle to pass through is arranged on the positioning insert block. Through the above improvement, it can be judged whether the mold closing between the top plate and the upper mold base is complete by whether the injection needle passes through the positioning hole.

[0012] As an improvement of the present utility model, a hole-forming needle for forming the hole-shaped structure on the clutch housing is fixedly connected to the top plate. The multi-stage die splitting assembly includes a driving connecting plate, a rotating connecting plate and a locking block. The driving connecting plate is arranged along the height direction, and one end of the driving connecting plate is fixedly connected to the top plate. The rotating connecting plate is rotatably connected to the upper die base. The locking block is fixedly connected to the lower die base. An inclined block is provided at one end of the rotating connecting plate close to the top plate. The inclined block is arranged on the side of the rotating connecting plate close to the driving connecting 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 connecting plate close to the rotating connecting 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. 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 closed die state, the hook block is engaged with the locking block. During the mold opening process, after the rotating connecting plate rotates, the hook block is separated from the locking block. Through the above improvement, after the top plate moves a certain distance, the movement of the driving connecting plate drives the rotation of the rotating connecting plate, so as to release the locking between the upper die base and the lower die base, thereby ensuring the smoothness of the mold splitting of the upper die base.

[0013] 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 rotated by the driving connecting plate. 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 the above improvement, not only can the rotated rotating connecting plate be reset, but also the over-rotation of the rotating connecting plate can be avoided, and the rotation angle of the rotating connecting plate is limited within a certain range to avoid interference with other structures.

[0014] 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 the above 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.
