Description

Technical Field

[0001] This utility model belongs to the field of automotive connector mold technology, and in particular relates to a front mold insert slider mold structure. Background Technology

[0002] Automotive connector molds have a structure where the front mold core needs to be inserted into the slider core hole when the mold is closed. Using a hydraulic cylinder structure would increase mold costs and molding cycle time. Therefore, a simpler bent pin structure is used. This structure has the following problems: 1. When the mold closes, the slider cannot close completely first, causing the front mold core to collide and be damaged; 2. When the mold opens, the slider opens before the front mold core is removed from the slider core hole, damaging both the front mold core and the slider core, making mold production impossible. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide a front mold insert slider mold structure, which effectively solves the problems of high cost and easy mold damage.

[0004] The technical solution to the technical problem is as follows: it includes a slider seat, with multiple frames fixed on the left side of the slider seat, a slider core fixed inside the frame, a front model core slidably connected inside the slider core, a through groove running vertically through the middle of the slider seat, a first inclined surface, a first straight surface, a second straight surface and a second inclined surface inside the through groove, a bent pin on the slider seat, the bent pin including a vertical part and an inclined part, the vertical part having a third straight surface corresponding to the first straight surface, the vertical part having a fourth straight surface corresponding to the second straight surface, and the inclined part passing through the through groove vertically.

[0005] Preferably, the number of frames is two.

[0006] Preferably, the top end of the bent pin is provided with a mounting hole.

[0007] This invention has the following advantages over traditional equipment: 1) It has a simple structure and is easy to operate. When the mold is closed, the slider seat moves to the mold closing position first, and then the front mold core will be inserted with the slider core. It has good stability and high accuracy. 2) When the mold is opened, the front mold core is pulled out from the slider core first, and the slider seat opens afterward. This avoids damage to the front mold core and the slider core. It has low cost and high safety. Attached Figure Description

[0012] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0013] Depend on Figures 1 to 3 A front mold insert slider mold structure is provided, including a slider seat 1. Multiple frames 2 are fixed on the left side of the slider seat 1. A slider core 3 is fixed inside the frame 2. A front mold core 4 is slidably connected to the slider core 3. A through groove 5 is provided in the middle of the slider seat 1. The through groove 5 is provided with a first inclined surface 6, a first straight surface 7, a second straight surface 8, and a second inclined surface 9. A bent pin 10 is provided on the slider seat 1. The bent pin 10 includes a vertical part 101 and an inclined part 102. The vertical part 101 is provided with a third straight surface 11 corresponding to the first straight surface 7 and a fourth straight surface 12 corresponding to the second straight surface 8. The inclined part 102 passes through the through groove 5 vertically.

[0014] The number of frames 2 is two.

[0015] The top end of the bent pin 10 is provided with a mounting hole 13.

[0016] In use, the vertical part 101 is located above the inclined part 102. The mold includes an upper mold and a lower mold. The lower mold is provided with a limiting groove corresponding to the inclined part 102. When the mold is closed, the bent pin 10 passes downward through the through groove 5. The distance between the first inclined surface 6 and the second straight surface 8 is sufficient to ensure that the inclined part 102 passes through. The distance between the second inclined surface 9 and the first straight surface 7 is also sufficient to ensure that the inclined part 102 passes through. Since the first straight surface 7 corresponds to the third straight surface 11 and the second straight surface 8 corresponds to the fourth straight surface 12, the first straight surface 7 and the second straight surface 8 form a first distance, and the third straight surface 11 and the fourth straight surface 12 form a second distance. The distance between the first and second gaps is the same. Therefore, during the downward movement of the bent pin 10 in the through groove 5, the inclined part 102 drives the slider seat 1 to slide to the left. When the third straight surface 11 is in contact with the first straight surface 7, and the fourth straight surface 12 and the second straight surface 8 are in contact, the bent pin 10 presses the slider seat 1 to the mold closing state. At this time, the inclined part 102 is located in the limiting groove of the lower mold, realizing the left and right limiting of the bent pin 10 on the slider seat 1. The top of the bent pin 10 is provided with a mounting hole 13. The mounting hole 13 is fixed to the upper mold by bolts. Then the front mold core 4 is inserted downward into the slider core 3. The upper mold and the lower mold continue to be closed and fixed. Finally, the mold closing is completed.

[0017] When the mold is opened, the third straight surface 11 is in contact with the first straight surface 7, the fourth straight surface 12 is in contact with the second straight surface 8, and the bent pin 10 limits the slider seat 1. The front mold core 4 is first pulled out from the slider core 3 upwards, which has good stability and facilitates the separation of the front mold core 4 from the slider core 3. Then the bent pin 10 moves upwards to reset, and the inclined part 102 first disengages from the limiting groove of the lower mold. Then the inclined part 102 drives the slider seat 1 to slide to the right to reset, the slider seat 1 opens, and the mold opening is completed.

[0018] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
