The number of the fourth inverted buckle 104 is two, and the two fourth inverted buckles 104 are arranged on both sides of the product. Since the multi-inverted product 1 has the characteristics of small volume, narrow space inside the product, many inverted buckles and long stroke, the core pulling is difficult. The existing core pulling structure scheme is that each inverted buckle adopts an independent core pulling slider and a hydraulic cylinder for core pulling. The scheme has a simple structure and the core pulling sequence of the core pulling slider is convenient to control. However, the addition of multiple hydraulic cylinders leads to a larger equipment size design and a higher production cost, which is not conducive to the promotion of technology.

[0030] Through the arrangement of the multi-inverted slider assembly, the first core-pulling cylinder 4 can simultaneously drive the first core-pulling slide rod and the second core-pulling slide rod to move backwards. Under the action of the core-pulling guide 3, the first core-pulling slide rod 9 and the second core-pulling slide rod 11 simultaneously perform core pulling in a direction away from the multi-inverted product 1, so that the third inverted 103, the fifth inverted 105 and the sixth inverted 106 can perform core pulling actions simultaneously, effectively reducing the number of core-pulling cylinders required, controlling production costs, and achieving cost reduction and efficiency improvement.

[0031] The multi-undercut slider assembly, the slider assembly, the core pulling guide 3, the first core pulling cylinder 4 and the second core pulling cylinder 5 constitute a core pulling assembly.

[0035] By setting the first slide bar guide groove 31 and the second slide bar guide groove 32, the movement of the first core-pulling slide bar 82 and the second core-pulling slide bar 83 can be effectively limited. The connection between the first slider guide groove 33 and the first slide bar guide groove 31 makes the cooperation between the first core-pulling slider 9 and the first core-pulling slide bar 82 more stable. The connection between the second slider guide groove 34 and the second slide bar guide groove 32 makes the cooperation between the second core-pulling slider 11 and the second core-pulling slide bar 83 more stable. The cooperation between the first guide ridge 92 and the first guide groove 331 can effectively guide the first core-pulling slider 9. The cooperation between the second guide ridge 112 and the second guide groove 341 can effectively guide the second core-pulling slider 11.

[0036] A third core-pulling slider 12 is also provided on the connecting insert 81 . A second contour surface is provided on one end of the third core-pulling slider 12 facing the multi-undercut product 1 . The movement direction of the third core-pulling slider 12 is the same as that of the movement end of the first core-pulling cylinder 4 .

[0037] By setting the third core-pulling slider 12, the first core-pulling cylinder 4 can simultaneously pull the second undercut 102 during the core-pulling process, further reducing the number of core-pulling cylinders required, controlling production costs, and achieving cost reduction and efficiency improvement.

[0038] The manufacturing equipment of the high-quality multi-inverted product also includes a plug screw 13. Two core pulling protrusions 35 are provided on the end of the core pulling guide 3 facing the multi-inverted product 1. The core pulling protrusion 35 is provided with a third contoured surface 351 that cooperates with the multi-inverted product 1. The movement direction of the core pulling guide 3 is the same as the movement direction of the moving end of the first core pulling cylinder 4. A screw head 131 is provided on the plug screw 13. A sliding channel 811 that cooperates with the plug screw 13 is provided on the connecting insert 81. The plug screw 13 is fixedly arranged on the core pulling guide 3 at one end away from the screw head 131. The screw head 131 can slide relatively in the sliding channel 811. The movement direction of the plug screw 13 is the same as the movement direction of the moving end of the first core pulling cylinder 4.

[0039] Through the arrangement of the two core pulling protrusions 35, the first core pulling cylinder 4 can continue to move after pulling the core backwards for a specified distance, thereby driving the core pulling protrusion 35 to move backwards, and pull the core of the fourth undercut 104, further reducing the number of core pulling cylinders required, controlling production costs, and achieving cost reduction and efficiency improvement.

[0040] Due to the setting of the plug screw 13, after the connecting insert 81 moves a specified distance, a blocking block 8111 is set in the sliding channel 811. The blocking block 8111 limits the screw head 131 in the sliding channel 811. The first core pulling cylinder 4 continues to move backward and drives the core pulling guide 3 to move together.

[0041] The connecting insert 81 is also provided with a guide limit insert 14, a linear insert 15 and a fourth core-pulling slider 16. The fourth core-pulling slider 16 is arranged between the first core-pulling slider 82 and the second core-pulling slider 83. The guide limit insert 14 is provided with a linear guide groove 141 that cooperates with the linear insert 15. The linear insert 15 can move linearly in the linear guide groove 141. A limit boss 151 is provided on the linear insert 15. A limit baffle 1411 that cooperates with the limit boss 151 is provided at the outlet end of the linear guide groove 141. The limit boss 151 can move linearly with the limit baffle 1 411 cooperates to prevent the linear insert 15 from escaping from the linear guide groove 141.

A third guide portion cooperating with the fourth core-pulling slider 16 is arranged on the core-pulling guide member 3. The third guide portion can limit the movement direction of the fourth core-pulling slider 16. A fourth contoured surface is arranged on the side of the fourth core-pulling slider 16 facing the multi-undercut product 1. The movement direction of the linear insert 15 is the same as the movement direction of the moving end of the first core-pulling cylinder 4.

[0042] By setting the fourth core-pulling slider 16, the first core-pulling cylinder 4 can continue to move backward after pulling the core a specified distance, thereby driving the fourth core-pulling slider 16 to move backward to pull the core of the first undercut 101, further reducing the number of core-pulling cylinders required, controlling production costs, and achieving cost reduction and efficiency improvement.

[0043] With the cooperation of the linear guide groove 141 and the linear insert 15, the guide limit insert 14 can move backward to the specified position together with the connecting insert 81. With the cooperation of the limit boss 151 and the limit baffle 1411, the first core pulling cylinder 4 continues to move backward, driving the linear insert 15 to move together.

[0044] The manufacturing equipment of the high-quality multi-undercut product further comprises a limiting cover 17 , one end of which is fixedly arranged on the core-pulling guide 3 , and the other end of which is arranged above the linear guide groove 141 .

[0045] The limiting cover 17 can further prevent the linear insert 15 from being separated from the linear guide groove 141 .

[0046] The linear insert 15 is provided with a second T-shaped groove 152 at a position corresponding to the third sliding inclined surface, and the fourth core-pulling slider 16 is provided with a second T-shaped protrusion 162 matched with the second T-shaped groove 152 .

[0047] The cooperation between the second T-shaped groove 152 and the second T-shaped protrusion 162 can make the sliding connection between the linear insert 15 and the fourth core-pulling slider 16 more stable.

[0048] The third guide portion is an oblique guide groove 36 provided on the core pulling guide member 3 , and the fourth core pulling slider 16 is provided with an oblique convex strip 163 matched with the oblique guide groove 36 .

[0049] Through the cooperation of the oblique guide groove 36 and the oblique convex strip 163, the movement direction of the fourth core-pulling slider 16 can be made more stable, the linear insert 15 moves backward, and the fourth core-pulling slider 16 moves obliquely upward to pull the core backward.

[0050] The slider assembly includes a fifth core-pulling slider 18 and a sliding connection block 19. The fifth core-pulling slider 18 is provided with a fifth contour surface at one end facing the multi-undercut product 1. The fifth core-pulling slider 18 is fixedly arranged on the sliding connection block 19. The movement direction of the fifth core-pulling slider 18 is the same as the movement direction of the moving end of the second core-pulling cylinder 5.

[0051] By disposing the fifth core-pulling slider 18 , the second core-pulling cylinder 5 can pull the seventh undercut 107 when driving the sliding connection block 19 to move backward.

[0052] The first core-pulling cylinder 4 is arranged obliquely upward, and the second core-pulling cylinder 5 is arranged horizontally. The first core-pulling cylinder 4 and the second core-pulling cylinder 5 are arranged on the same side and are arranged up and down.

[0053] The number of the injection molding spaces for multiple undercut products is two, and the two injection molding spaces for multiple undercut products are arranged side by side.

[0054] Since the first core-pulling cylinder 4 and the second core-pulling cylinder 5 are arranged on the same side, the core pulling of the two injection molding spaces for multiple undercut products does not affect each other and can work independently. Moreover, the interval between the two injection molding spaces for multiple undercut products can be effectively compressed, thereby improving work efficiency and effectively controlling product size.

[0055] And it is obvious that since the main function of the two sets of slider assemblies is to pull the core of the seventh undercut 107 of the multi-undercut product 1 in the injection molding space of two multi-undercut products, when designing the specific equipment structure, the two fifth core-pulling sliders 18 can be installed on the drive mounting plate at the same time, and the moving end of the second core-pulling cylinder 5 is connected to the drive mounting plate, sharing a second core-pulling cylinder 5, thereby ensuring that the processing efficiency remains unchanged and further reducing the production of finished products of the equipment.

[0056] This embodiment provides a core pulling process of a high-quality multi-undercut product manufacturing device as follows: The embodiment of the present invention provides an advantage of low cost and simple structure compared to the existing manufacturing equipment for multi-undercut products 1.

[0057] First, the second core-pulling cylinder 5 drives the fifth core-pulling slider 18 to move backward by 90 mm, and the fifth core-pulling slider 18 escapes from the seventh undercut 107 .

[0058] Subsequently, the first core-pulling cylinder 4 drives the connecting insert 81 to move backward by 30 mm, and the first core-pulling slide bar 82 , the second core-pulling slide bar 83 and the guide limit insert 14 move backward by 30 mm along with the connecting insert 81 .

[0059] During this process, under the action of the first sliding slope, the second sliding slope, the first guide portion and the second guide portion, the first core-pulling slider 9 and the second core-pulling slider 11 move away from the multi-undercut product 1, and are separated from the third undercut 103, the fifth undercut 105 and the sixth undercut 106 by 12.73 mm respectively.

[0060] After the disengagement is completed, the first core-pulling cylinder 4 continues to drive the first core-pulling slide 82, the second core-pulling slide 83, the guide limit insert 14 and the connecting insert 81 to move backward by 20 mm, and the first core-pulling slider 9 and the second core-pulling slider 11 continue to disengage by 8.49 mm from the third undercut 103, the fifth undercut 105 and the sixth undercut 106. At the same time, the limiting boss 151 of the linear insert 15 cooperates with the limiting baffle 1411, and the guide limit insert 14 drives the linear insert 15 to move backward by 20 mm. Under the action of the third inclined sliding and the third guide part, the fourth core-pulling slider 16 performs a core-pulling movement and disengages by 16.18 mm from the first undercut 101 in the multi-undercut product 1.

[0061] In the above two-stage movement of the first core-pulling cylinder 4, since the third core-pulling slider 12 is fixed on the connecting insert 81, and the movement direction of the third core-pulling slider 12 is the same as the movement direction of the moving end of the first core-pulling cylinder 4, the third core-pulling slider 12 is separated from the second undercut 102 in the multi-undercut product 1 by 50 mm, and under the action of the plug screw 13, the connecting insert 81 moves backward by 50 mm, and the position of the core-pulling guide 3 always remains fixed.

[0062] After the first core-pulling cylinder 4 moves backward 50 mm, the screw head 131 of the driving screw 13 fits with the blocking block 8111, and the first core-pulling cylinder 4 continues to move backward 60 mm. The core-pulling guide 3 moves backward 60 mm along with the connecting insert 81, and the core-pulling protrusion 35 disengages from the fourth undercut 104, realizing the multi-undercut core-pulling process of the product.

[0063] It can be seen from the above that the present invention provides a high-quality manufacturing equipment for multi-inverted products. By arranging a multi-inverted slider assembly, a slider assembly and a core pulling guide 3 that cooperate with each other in the manufacturing equipment for high-quality multi-inverted products, the multi-inverted slider assembly is arranged, and the first core pulling cylinder 4 can simultaneously drive the first core pulling slide rod and the second core pulling slide rod to move backward. Under the action of the core pulling guide 3, the first core pulling slider 9 and the second core pulling slider 11 simultaneously pull the core in the direction away from the multi-inverted product 1, so that the third inverted 103, the fifth inverted 105 and the sixth inverted 106 can be pulled together at the same time, which effectively reduces the number of core pulling cylinders required, controls the production cost, achieves cost reduction and efficiency improvement, and solves the problem that the manufacturing equipment in the prior art needs to use an independent core pulling slider and hydraulic cylinder for each inverted for core pulling, and the equipment has large size and high cost, which is not conducive to the promotion of technology.

[0064] The specific implementation modes described above are preferred implementation modes of the present invention, and are not intended to limit the specific implementation scope of the present invention. The scope of the present invention includes but is not limited to the specific implementation modes, and all equivalent changes made according to the present invention are within the protection scope of the present invention.
