Description

Technical Field

[0001] This utility model relates to the field of mold slider oblique pulling technology, specifically a slider oblique pulling mechanism. Background Technology

[0002] In the field of injection molds, for parts with side holes or side recesses, a special mechanism is needed to achieve lateral parting and core pulling to meet the molding and demolding requirements of the parts. For example, parts such as turnover boxes, coil frames, and external threads have shallow side holes or side recesses, requiring little core pulling force, but with a large molding area. This requires an effective mechanism to complete the lateral core pulling.

[0003] In existing technologies, for parts with side holes or side recesses, a special wedge slider mechanism is required to achieve lateral parting and core pulling. However, in actual use, the traditional wedge slider mechanism occupies a relatively large space and has a complex structure when applied in progressive dies, resulting in high design and manufacturing costs, which is not conducive to the manufacturing of small parts. Therefore, it is necessary to improve the slider oblique pulling mechanism. Utility Model Content

[0004] The purpose of this invention is to provide a slider oblique pulling mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slider oblique extraction mechanism, including a guide block, a slider seat slidably connected to the inner side of the guide block, the slider seat and a slider oblique extraction seat fixedly connected by a second fixing bolt, the slider seat and a slider insert pressure plate fixedly connected by a first fixing bolt, a slider insert fixedly connected inside the slider insert pressure plate, a product abutting on the left side of the slider insert, an oblique groove opened inside the slider seat, a roller movably connected to the inner side of the slider oblique extraction seat, and a slider oblique extraction mechanism rotatably connected to the outside of the roller, so that the slider oblique extraction is restricted by the oblique groove. When the slider seat retracts, the oblique surface of the oblique groove will force the slider oblique extraction mechanism to move along an oblique trajectory, thereby being extracted from the product undercut.

[0006] Preferably, the slider seat has a through hole, and the first slider inclined draw seat has a threaded hole. The second fixing bolt passes through the through hole of the slider seat and is screwed into the threaded hole of the first slider inclined draw seat. The contact surfaces of the slider seat and the first slider inclined draw seat are tightly fitted, which facilitates fixing the slider seat and the first slider inclined draw seat.

[0007] Preferably, there are four fixing bolts, the slider insert pressure plate has a through hole, the slider seat has a threaded hole, the fixing bolt passes through the through hole of the slider insert pressure plate and is screwed into the threaded hole of the slider seat, and the contact surfaces of the slider seat and the slider insert pressure plate are tightly fitted, which facilitates fixing the slider seat and the slider insert pressure plate.

[0008] Preferably, the slider has an inclined groove at the position corresponding to the roller, and the roller is movably connected in the groove to restrict the movement of the roller.

[0009] Preferably, the slider insert pressure plate has a groove at the corresponding position of the slider insert, and the slider insert is fixedly connected in the groove to facilitate fixing the slider insert.

[0010] Preferably, a hole is provided at the position corresponding to the slider oblique pull of the product, and the slider oblique pull is inserted into the hole to facilitate product positioning.

[0011] Compared with the prior art, the present invention provides a slider oblique pulling mechanism, which has the following beneficial effects:

[0012] 1. In this slider oblique pulling mechanism, when the mold opens, the moving mold begins to move, and the injection molding machine tie rod drives the entire moving mold to move. When the slider oblique pulling is started, oblique demolding begins. The guide roller of the slider oblique pulling contacts the working surface of the oblique groove. At the same time, when the mold is fully opened, the main parting surface of the product separates. The moving mold continues to move to the set mold opening distance, and the slider oblique pulling is completed and moves away from the product. The slider oblique pulling completely exits the undercut area of ​​the product, so that the device can achieve fast and accurate lateral core pulling action, which avoids occupying a large space, simplifies the structure, avoids requiring more design and manufacturing costs, and is conducive to the manufacturing of small parts.

[0021] Example 1:

[0022] Based on the existing problems with the technology, please refer to Figure 1-4 This utility model provides a technical solution: a slider oblique extraction mechanism, including a guide block 1, a slider seat 2 slidably connected to the inner side of the guide block 1, the slider seat 2 and the slider oblique extraction seat 9 being fixedly connected by a second fixing bolt 3, the slider seat 2 and the slider insert pressure plate 5 being fixedly connected by a first fixing bolt 4, a slider insert 6 being fixedly connected inside the slider insert pressure plate 5, a product 7 abutting on the left side of the slider insert 6, an oblique through groove 8 being opened inside the slider seat 2, a roller 11 being movably connected to the inner side of the slider oblique extraction seat 9, and a slider oblique extraction 10 being rotatably connected to the outside of the roller 11, so that the slider oblique extraction 10 is restricted by the oblique groove. When the slider seat 2 retracts, the oblique surface of the oblique groove will force the slider oblique extraction 10 to move along the oblique trajectory, thereby being extracted from the product 7 under the inverted.

[0023] Furthermore, the slider seat 2 is provided with a through hole, and the slider first inclined draw seat 9 is provided with a threaded hole. The fixing bolt 2 3 passes through the through hole of the slider seat 2 and is screwed into the threaded hole of the slider first inclined draw seat 9. The contact surfaces of the slider seat 2 and the slider first inclined draw seat 9 are tightly fitted, which facilitates fixing the slider seat 2 and the slider first inclined draw seat 9.

[0024] Furthermore, there are four fixing bolts 4, and the slider insert pressure plate 5 is provided with a through hole, and the slider seat 2 is provided with a threaded hole. The fixing bolts 4 pass through the through hole of the slider insert pressure plate 5 and are screwed into the threaded hole of the slider seat 2. The contact surfaces of the slider seat 2 and the slider insert pressure plate 5 are tightly fitted, which facilitates fixing the slider seat 2 and the slider insert pressure plate 5.

[0025] Furthermore, the slider-sloping seat 9 is provided with a sloping groove at the corresponding position of the roller 11, and the roller 11 is movably connected in the groove.

[0026] Furthermore, the slider-sloping seat 9 is provided with a sloping groove at the position corresponding to the roller 11, and the roller 11 is movably connected in the groove, which facilitates restricting the movement of the roller 11.

[0027] Furthermore, the slider insert pressure plate 5 has a groove at the corresponding position of the slider insert 6, and the slider insert 6 is fixedly connected in the groove to facilitate fixing the slider insert.

[0028] Furthermore, a hole is provided at the position corresponding to the product 7 and the slider 10, and the slider 10 is inserted into the hole to facilitate positioning of the product 7.

[0029] Firstly, in the mold-closed state, the slider seat 2, slider insert 6, and inclined pull seat are all reset. The inclined pull 10 is inserted into the undercut area of ​​the product 7, completing the cavity closure. When the mold opens, the moving mold begins to move, and the injection molding machine pull rod drives the entire moving mold to move. The slider seat 2 is connected to the moving mold through the inclined through groove 8, maintaining synchronous movement. The inclined pull mechanism is pre-disengaged, and the slider insert 6 begins to separate from the main body of the product 7. The inclined pull 10 remains stationary (at this time, the inclined groove has not yet been activated). When the inclined pull 10 is activated, the slider seat 2 continues to retreat, and the slider-inclined pull seat 9, which is rigidly connected by the fixing bolt 4, moves synchronously to the right. The inclined demolding begins, and the guide roller 11 of the inclined pull 10 contacts the working surface of the inclined groove. At the same time, when the mold is fully opened, the main parting surface of the product 7 separates, and the moving mold continues to move to the set mold opening distance. The inclined pull 10 completes to move away from the product 7 and completely exits the undercut area of ​​the product 7. This allows the device to achieve fast and accurate lateral core pulling action, avoiding the need for a large space and simplifying the structure.
