Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a die-casting mold structure that can be processed to have a deep cavity and an isolated structure. Background Technology

[0002] To shorten product production cycles and reduce costs, die casting is widely used in the processing of automotive parts. Furthermore, once mold development is complete, mass production begins, reducing repeated process development and verification. Simultaneously, multiple parts are designed directly into a single large, integrated component, resulting in increasingly complex parts. For example... Figure 7 There is an integrated component 1, which has a deep cavity and an isolated structure 11 integrally formed in the deep cavity. For this type of integrated component, the traditional processing method often uses local extrusion, but this processing method can only solve the problem of shrinkage caused by local thickness, and cannot effectively solve the defects such as air holes and cold material caused by poor filling of isolated or deep cavity structures. Utility Model Content

[0003] This invention provides a die-casting mold structure that can process die-casting parts with deep cavities and isolated structures, which can improve the problem of difficult forming or poor forming quality of die-casting parts with deep cavities and isolated structures.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] A die-casting mold structure capable of processing deep cavities and isolated structures includes a moving mold frame, a moving mold core mounted on the moving mold frame, a fixed mold frame, and a fixed mold core mounted on the fixed mold frame and cooperating with the moving mold core. A product cavity is formed between the moving mold core and the fixed mold core. The moving mold core has an isolated structural cavity whose upper end is connected to the product cavity and a slag-filled sliding groove connected to the lower end of the isolated structural cavity. The die-casting mold structure also includes a linear drive and a shearing insert. One end of the shearing insert is detachably connected to the drive end of the linear drive, and the other end is slidably connected to the moving mold core. The other end of the shearing insert extends toward the part where the isolated structural cavity and the slag-filled sliding groove are connected.

[0006] The beneficial effects of this utility model are as follows: By opening a connected product cavity and an isolated structural cavity, and utilizing die casting between the moving mold core and the fixed mold core, the die casting material between the connected product cavity and the isolated structural cavity forms an integrated component, and the isolated structure of the integrated component fills the isolated structural cavity. After molding, the shearing insert is driven to move by a linear drive component, so that the shearing insert slides toward the part connected to the isolated structural cavity and the slag pot sliding groove, and shears the slag pot that extends out of the isolated structural cavity and enters the slag pot sliding groove, so as to complete the one-time molding of the integrated component. By adopting this integral die casting processing method, the problem of difficult molding or poor molding quality of die castings with deep cavities and isolated structures is improved by the existing local extrusion molding method.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the shearing insert includes an insert body and a shearing blade. The insert body is slidably connected to the moving mold core, and one end is detachably connected to the driving end of the linear drive. One end of the shearing blade is fixedly connected to the other end of the insert body, and the other end extends toward the part that connects the isolated structural cavity and the slag bag sliding groove.

[0009] The beneficial effects of adopting the above-mentioned further solution are: during die casting, the shearing insert is driven to move by a linear drive component, and the insert body and the shearing blade slide relative to the moving mold core at the same time. The shearing blade shears the slag bag that extends out of the isolated structural cavity and enters the slag bag sliding groove.

[0010] Furthermore, the side wall of the moving mold core is provided with an inner sliding groove that connects to the slag bag sliding groove, and the insert body is slidably connected to the inner sliding groove.

[0011] The advantage of adopting the above-mentioned further solution is that the insert body can be slidably installed through the inner groove with a lateral opening.

[0012] Furthermore, the inner sliding groove has a sleeve groove in its groove wall, and a sleeve is installed in the sleeve groove, with the insert body slidably connected to the sleeve.

[0013] The advantages of adopting the above-mentioned further solution are: the sliding of the insert body is precisely guided by the insert sleeve, and the insert body is slidably installed by the insert sleeve. Only the insert sleeve needs to be precisely processed and the material of the insert sleeve needs to be carefully selected, which can reduce costs.

[0014] Furthermore, the insert includes a mating section and a clearance section, both of which have through-open structures. The inner diameter of the mating section is equal to the outer diameter of the insert body, and the inner diameter of the clearance section is greater than the outer diameter of the insert body. The clearance section forms a clearance groove with the outer wall of the insert body that opens outward away from the mating section. The clearance groove is connected to the inner hole of the mating section through an inclined surface. One end of the shearing blade is fixedly connected to the mating section.

[0015] The beneficial effects of adopting the above-mentioned further scheme are: when installing the shearing insert, the clearance groove with an opening size larger than the outer diameter of the insert body facilitates the insertion of the shearing insert. After the shearing insert is inserted into the clearance groove, under the guiding action of the inclined surface, the shearing insert can be smoothly guided into the mating section, and under the limiting action of the mating section, the straightness of the shearing insert during slag bag shearing operation is guaranteed.

[0016] Furthermore, the side wall of the moving mold core is provided with a cover plate groove that communicates with the insert groove, and the cover plate groove is adapted to be detachably connected to the moving mold core. The cover plate is annular, and its inner diameter is not less than the groove diameter of the clearance groove, and its outer diameter is not less than the outer diameter of the clearance section.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the sleeve groove can be exposed by removing the cover plate to facilitate the installation of the sleeve. After the sleeve is installed, the cover plate is installed to fix the sleeve. Then, the shearing insert can be inserted into the sleeve through the inner hole of the cover plate.

[0018] Furthermore, the contact surfaces of the moving mold frame and the fixed mold frame are provided with slots, and the two slots are connected to form an outer sliding groove. The outer sliding groove is connected to the inner sliding groove and simultaneously passes through the outer sides of the moving mold frame and the fixed mold frame. A connecting ring is slidably installed in the outer sliding groove, and the connecting ring is simultaneously connected to the driving end of the linear drive member and one end of the insert body.

[0019] The beneficial effect of adopting the above-mentioned further solution is that after the shearing insert is installed in the inner slide groove, the driving end of the linear drive and the end of the insert body are connected by the connecting ring. At this time, the connecting ring is located in the slot of the moving mold frame. Then the mold is closed to form the outer slide groove. The connecting ring is limited and installed by the outer slide groove. During use, as the linear drive is driven, the connecting ring and the shearing insert slide simultaneously, and the connecting ring slides in the outer slide groove.

[0020] Furthermore, the connecting ring includes a moving plate and a fixed plate with openings facing each other, and the end of the insert body and the driving end of the linear drive member are simultaneously engaged in the openings of the moving plate and the fixed plate.

[0021] The beneficial effect of adopting the above-mentioned further solution is that it enables the rapid connection of the linear drive component and the shearing insert through the separate moving plate and fixed plate.

[0022] Furthermore, a first locking block is fixedly connected to the end of the insert body. The cross-sectional dimension of the first locking block is larger than the cross-sectional dimension of one end of the insert body. A second locking block is fixedly connected to the driving end of the linear drive member. The cross-sectional dimension of the second locking block is larger than the cross-sectional dimension of the driving end of the linear drive member. The first locking block and the second locking block abut against each other and are simultaneously locked in the openings of the moving locking plate and the fixed locking plate.

[0023] The beneficial effect of adopting the above-mentioned further solution is that the first and second locking blocks can be simultaneously locked in the openings of the moving and fixed locking plates, thereby quickly realizing the connection between the linear drive component and the shearing insert.

[0024] Furthermore, the outer slide groove includes a left slide section, a middle slide section, and a right slide section connected in sequence. The opening size of the left slide section and the right slide section is smaller than the opening size of the middle slide section. The left slide section is connected to the inner slide groove. The connecting ring is slidably connected to the middle slide section. The driving end of the linear drive member extends and retracts in the right slide section.

[0025] The beneficial effect of adopting the above-mentioned further solution is that the sliding of the connecting ring is limited by the middle groove section. Attached Figure Description

A product cavity 51 is formed between the moving mold core 3 and the fixed mold core 5. The moving mold core 3 has an isolated structure cavity 31 with its upper end connected to the product cavity 51 and a slag-filled sliding groove 32 with its lower end connected to the isolated structure cavity 31. The die-casting mold structure also includes a linear drive 6 and a shearing insert 7. One end of the shearing insert 7 is detachably connected to the drive end of the linear drive 6, and the other end is slidably connected to the moving mold core 3. The other end of the shearing insert 7 extends to the part where the isolated structure cavity 31 and the slag-filled sliding groove 32 are connected.

[0046] The beneficial effects of this embodiment are as follows: by opening the interconnected product cavity 51 and the isolated structural cavity 31, and using the die casting between the moving mold core 3 and the fixed mold core 5, the die casting material between the interconnected product cavity 51 and the isolated structural cavity 31 forms an integrated component 1, and the isolated structure 11 of the integrated component 1 fills the isolated structural cavity 31. After molding, the shearing insert 7 is driven to move by the linear drive 6, so that the shearing insert 7 slides toward the part that connects the isolated structural cavity 31 and the slag pot sliding groove 32, and shears the slag pot that extends out of the isolated structural cavity 31 and enters the slag pot sliding groove 32, so as to complete the one-time molding of the integrated component 1. By adopting this integral die casting processing method, the problem of difficult molding or poor molding quality of die castings with deep cavities and isolated structures is improved by the existing local extrusion molding method.

[0047] As a specific embodiment of the above, the slag bag sliding groove 32 includes a vertically arranged vertical groove 321 and a sliding groove 322 connecting the vertical groove 321. The vertical groove 321 connects to the isolated structural cavity 31 and extends vertically through the moving mold core 3. The sliding groove 322 extends laterally through the side wall of the moving mold frame 2, so that after the slag bag falls into the vertical groove 321, it slides out through the sliding groove 322, completing automatic cleaning. Moreover, the sliding groove 322 is an inclined groove to ensure that the slag bag slides out automatically under its own gravity.

[0048] The linear drive unit 6 includes a mounting plate and a drive motor, with the drive motor fixedly connected to the side wall of the fixed mold frame 4 via the mounting plate.

Only the insert 8 needs to be precisely processed and the material of the insert 8 needs to be carefully selected, which can reduce costs.

[0058] Example 5

[0059] like Figures 2 to 4 Based on embodiments 1-4, the insert 8 includes a mating section 81 and a clearance section 82, both of which have through-open structures. The inner diameter of the mating section 81 is equal to the outer diameter of the insert body 71. The inner diameter of the clearance section 82 is greater than the outer diameter of the insert body 71, and a clearance groove 83 is formed between the clearance section 82 and the outer wall of the insert body 71, opening outward away from the mating section 81. The clearance groove 83 is connected to the inner hole of the mating section 81 through an inclined surface. One end of the shearing blade 72 is fixedly connected to the mating section 81.

[0060] The beneficial effect of the preferred solution in the above embodiments is that, when installing the shearing insert 7, the clearance groove 83 with an opening size larger than the outer diameter of the insert body 71 facilitates the insertion of the shearing insert 7. After the shearing insert 7 is inserted into the clearance groove 83, under the guiding action of the inclined surface, the shearing insert 7 can be smoothly guided into the mating section 81, and under the limiting action of the mating section 81, the straightness of the shearing insert 7 during the slag bag shearing operation is guaranteed.
