[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] like Figure 1 As shown, in this solution, an oblique pull-out conversion structure with a quick-change function used in a die-casting mold is mainly described in detail, but the oblique pull-out conversion structure with a quick-change function is not limited to being used in a die-casting mold, and can also be applied to other molds, such as injection molds.

[0028] like Figures 1 to 3As shown, an oblique withdrawal conversion structure with a quick-change function is used to form an obliquely arranged through hole in the product cavity formed by the fixed mold base 1 and the movable mold base 2, wherein the structure comprises: a driving component 3, which is arranged on the fixed mold base 1, and a driving block 30 that can move back and forth in the horizontal direction is movably arranged on the driving component 3, and an obliquely placed protrusion block 300 is formed at the end of the driving block 30, and the protrusion block 300 and the driving block 30 jointly form a traction portion 301; a sliding block 4, whose moving direction is set at an angle to the moving direction of the driving block 30, and a traction block 40 is formed on the sliding block 4, and the traction block 40 and the sliding block 4 jointly form a clamping portion 4 1. The traction block 40 is movably engaged with the traction portion 301, and the protruding block 300 is movably pressed against and engaged in the engaging portion 41; the forming rod 5 and a plurality of blocking blocks 6, the forming rod 5 is connected in the sliding block 4, and is used to be movably inserted into the forming through hole in the product cavity; a plurality of blocking blocks 6 are coaxially arranged in the sliding block 4 with the forming rod 5, one side of the blocking block 6 is movably pressed against the forming rod 5, and the other side is movably pressed against the protruding block 300; the sliding block 4 can drive the forming rod 5 to detach from the product cavity due to the movement of the traction portion 301, and when the engaging portion 41 detaches from the protruding block 300, the blocking block 6 and the forming rod 5 can be synchronously disassembled to the outside of the sliding block 4.

[0029] During the product molding process, the driving assembly 3 drives the driving block 30 to gradually approach the fixed mold base 1 in the horizontal direction. Since the moving direction of the traction part 301 is set at an angle with the inclined direction of the sliding block 4 itself, the traction block 40 can slide in the traction part 301 under the pull of the traction part 301, and then the sliding block 4 drives the molding rod 5 to be inserted into the product cavity along its own inclined direction. As the fixed mold base 1 and the movable mold base 2 complete the mold closing action, the injection molding material is injected into the cavity to form the through-hole structure required for the product; similarly, after the product is formed, the driving assembly 3 can drive the driving block 30 along the Figure 2The cam 300 of the embodiment of the present invention is provided with a plurality of sealing blocks 6, and it is worth noting that in the process of the traction block 40 and the traction part 301 being engaged with each other, the protruding block 300 is also engaged with the engaging part 41. The double engaging action ensures the smoothness and stability of the movement of the sliding block 4 driven by the driving block 30. It is precisely because of the structural design of the protruding block 300 against the engaging part 41 that the sealing block 6 is installed in the sliding block 4. One side of the blocking block 6 limits and fixes the forming rod 5, and the other side relies on the protruding block 300 to limit and fix the blocking block 6. In this way, when the forming rod 5 is worn or damaged, it is only necessary to disengage the protruding block 300 from the engaging portion 41 to take out the blocking block 6 to realize the rapid disassembly and replacement of the forming rod 5. The overall structure is relatively simple, and the stable insertion and rapid disassembly functions of the forming rod 5 are realized. While ensuring the stable forming of the through-hole structure on the product, it also greatly shortens the replacement time of the forming rod 5 and improves work efficiency.

[0030] The driving assembly 3 also includes a fixed bracket 31 and a driving member 32. The fixed bracket 31 is installed on the side wall of the fixed mold base 1. The driving member 32 is arranged on the fixed bracket 31 in the horizontal direction, and the driving end of the driving member 32 is connected to the driving block 30 to drive the driving block 30 to move relative to the fixed mold base 1.

[0031] Further, if Figures 1 to 2 As shown, the fixing bracket 31 and the driving member 32 in this embodiment are both arranged in the horizontal direction, so that when the driving member 32 is started, the driving end of the driving member 32 can push the driving block 30 along the horizontal direction. Figure 2 It moves left or right, and then relies on the cooperation of the traction part 301 and the traction block 40 to realize that the sliding block 4 drives the forming rod 5 to extend into or out of the product cavity. The overall structure is simple, and high-precision positioning and reliable stability of the forming rod 5 during movement are achieved, effectively improving production efficiency and product quality.

[0032] A fixed plate 10 is symmetrically provided on the fixed mold base 1 , and a limiting groove 100 is formed in the fixed plate 10 . The two side walls of the driving block 30 form limiting blocks 302 , and the limiting blocks 302 are movably engaged in the limiting groove 100 .

[0033] like Figure 1 and Figure 3As shown, the two fixed plates 10 in this embodiment are symmetrically mounted on the fixed mold base 1, and the space formed therebetween can allow the driving block 30 to reciprocate in the horizontal direction. Specifically, the length directions of the limiting groove 100 and the limiting block 302 are both arranged parallel to the moving direction of the driving block 30. In the process of the driving member 32 pushing the driving block 30 to move, the cooperation of the limiting groove 100 and the limiting block 302 can be utilized to ensure the precise movement of the driving block 30 in the horizontal direction, thereby avoiding lateral offset and shaking of the driving block 30 during movement, improving the stability of the overall structure, and providing a guarantee for the accuracy of the sliding block 4 driving the forming rod 5 to insert into or out of the product cavity.

[0034] The inner wall of the fixed plate 10 is further provided with an inclined groove 101 , which is communicated with the limiting groove 100 . The side wall of the sliding block 4 is provided with an inclined block 43 , which is movably engaged in the inclined groove 101 .

[0035] Similarly, the inclined groove 101 and the inclined block 43 in this embodiment are also consistent with the moving direction of the sliding block 4 and the forming rod 5. Under the cooperation of the inclined groove 101 and the inclined block 43, the accuracy and stability of the sliding block 4 driving the forming rod 5 to form the product are ensured, and the offset of the sliding block 4 during the movement process, which causes the forming rod 5 to become stuck, is avoided, and the molding quality of the product is effectively guaranteed.

[0036] A pressing plate 11 is detachably connected between two adjacent fixing plates 10 . The protruding block 300 , the traction portion 301 and the driving block 30 jointly form a recessed groove 303 . The traction portion 301 is connected to the recessed groove 303 , and the recessed groove 303 movably rests against the pressing plate 11 .

[0037] Continue to refer Figure 1 and Figure 3 In the process of the driving member 32 pushing the driving block 30 toward the fixed die seat 1, the cooperation between the pressing plate 11 and the recessed groove 303 further enhances the positioning accuracy of the driving block 30, ensures the accurate position of the forming rod 5 in the product cavity, and improves the quality and consistency of the product. Figure 2 In the mold closing state shown, it is exactly in the recessed groove 303, which further limits the vertical movement of the driving block 30, avoids the demolding phenomenon of the driving block 30 during the production process, helps to protect the safety of operators and equipment, and enhances the safety and reliability of the overall structure.

[0038] A stepped hole 42 is defined in the sliding block 4 , an assembly block 50 is connected to the end of the forming rod 5 , and the blocking block 6 is used to move the assembly block 50 against the inner wall of the stepped hole 42 to limit the movement of the forming rod 5 relative to the sliding block 4 .

[0039] like Figure 2As shown, for the disassembly of the forming rod 5 and the blocking block 6, the embodiment is provided with a stepped hole 42 in the sliding block 4, and it should be noted that the inclined direction of the stepped hole 42 is consistent with the inclined direction and moving direction of the sliding block 4 and the forming rod 5, and the length of the large-diameter inner hole in the stepped hole 42 is greater than the length of the small-diameter inner hole (wherein the large-diameter inner hole is close to the driving block 30, and the large-diameter inner hole is in communication with the above-mentioned clamping part 41, which can be referred to Figure 3 ), in the assembly process, the forming rod 5 and the assembly block 50 can be fixedly connected through the cooperation structure of the T-shaped groove (not shown in the figure) and the T-shaped hole (not shown in the figure), and as the forming rod 5 passes through the small-diameter inner hole and extends out of the sliding block 4, the assembly block 50 at this time also abuts against the inner wall of the large-diameter inner hole, at this time, the worker can insert the blocking block 6 into the large-diameter inner hole and abut against the assembly block 50, and as the clamping part 41 on the sliding block 4 and the protruding block 300 on the driving block 30 are movably abutted and clamped, the blocking block 6 is effectively limited to separate out of the sliding block 4, thereby ensuring the accuracy and stability of the forming rod 5 when inserting or separating from the product cavity.

[0040] Preferably, the number of the blocking block 6 in the embodiment can be adjusted according to actual needs to ensure the stability of the forming rod 5 during the forming or demolding action.

[0041] Preferably, the embodiment further provides a fixing sleeve 12 in the fixed mold base 1, and in the process of inserting or separating the forming rod 5 from the product cavity, the forming rod 5 can be movably inserted into the fixing sleeve 12, and the fixing sleeve 12 provides a stable guiding action for the forming rod 5, avoiding the error caused by movement to affect the forming quality of the product.

[0042] It should be noted that the driving member 32 in the scheme can be replaced by other driving devices such as hydraulic drive, air cylinder drive, etc.

[0043] It should be noted that all the directional indications (such as up, down, left, right, front, back, etc.) in the embodiment of the utility model are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications also change accordingly.
