[0002] During the injection molding process, when some injection molded products have multiple openings in different directions, the mold needs to have a core pulling function in the corresponding direction. For this problem, the current traditional molds all perform side core pulling actions by moving the oil cylinder in various angles. However, this traditional core pulling mechanism is relatively complex, large in size, and the processing procedures and subsequent maintenance are relatively cumbersome and costly. Therefore, in order to reduce costs and simplify the structure of the core pulling mechanism, the utility model provides a new type of sliding core pulling mechanism with a simple structure.

Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.
[0026] The angle core-pulling sliding mechanism of the injection mold of the preferred embodiment of the utility model is as follows Figure 1-7 As shown, it includes a slider seat 10 horizontally slidably arranged on the mold base A1, an inclined guide column 20 arranged on the movable mold A2 for pushing the slider seat 10 outward, a guide rail assembly 30 arranged on a side wall of the slider seat 10 facing the injection cavity A31 on the fixed mold A3, and a slider core-pulling insert 40 slidably arranged on the guide rail assembly 30, and a pressing block 50 arranged above the slider core-pulling insert 40 to limit it. A slider slide 60 adapted to the slider core-pulling insert 40 is arranged on the side wall of the fixed mold A3, and the slider slide 60 is connected with the injection cavity A31, so that the slider core-pulling insert 40 can extend into the injection cavity A31 to mold the injection product. The lower end of the pressing block 50 is provided with a downward protrusion 51, and the protrusion 51 is provided with a guide inclined surface 52 parallel to the moving direction of the slider core-pulling insert 40 to ensure that the slider core-pulling insert 40 can slide back and forth smoothly.
[0027] Among them, the guide rail assembly 30 includes a fixed seat 31 detachably connected to the slider seat 10, and a positioning inclined surface 70 is provided on the fixed seat 31, and the positioning inclined surface 70 faces the injection cavity A31. The guide rail assembly 30 also includes a guide rail body 32 arranged parallel to the positioning inclined surface 70. The slider core-pulling insert 40 is slidably connected to the guide rail body 32. When the movable mold A2 is opened, the inclined guide column 20 drives the slider seat 10 to move away from the injection cavity A31, and at the same time drives the slider core-pulling insert 40 to move through the guide rail assembly 30. Since the guide rail assembly 30 and the inclined guide column 20 are inclined in opposite directions, when the slider seat 10 is opened, the slider core-pulling insert 40 can slide down along the guide rail assembly 30 to leave the injection cavity A31, thereby completing the core-pulling action. The overall structure of the mechanism of this scheme is simple and easy to maintain, small in size, can be integrated inside the mold, and has lower processing costs and technical implementation difficulties.

[0029] In this embodiment, the lower ends of the two extension portions 53 are provided with limiting protrusions 54 opposite to each other, and the upper end of the guiding slope 52 is located between the two limiting protrusions 54. When assembled in place, the relative side walls of the two limiting protrusions 54 are in contact with the core-pulling insert 40 to further guide and limit the core-pulling insert 40 and prevent the core-pulling insert 40 from shaking left and right.
[0030] In this embodiment, the guide rail body 32 is in the shape of an elongated strip and its longitudinal cross-section is T-shaped. A T-shaped slot 80 that matches the guide rail body 32 is provided on the slide core-pulling insert 40. During assembly, the lateral end of the guide rail body 32 is inserted into the T-shaped slot 80, so that the slide core-pulling insert 40 can slide without falling off, and has good stability, simple structure and stability.
[0031] In this embodiment, a long strip-shaped positioning groove 90 is provided on the positioning inclined surface 70, and a positioning boss 100 adapted to the positioning groove 90 is provided on the longitudinal end surface of the guide rail body 32. A bolt 110 is penetrated through the upper end of the guide rail body 32, and the bolt 110 is threadedly connected to the bottom surface of the positioning groove 90 to further play the role of positioning the guide rail body 32 and ensure the stability of the operation of the sliding core insert 40.
[0032] In this embodiment, the slider core pulling insert 40 is a rectangular structure and the upper end is inclined toward the injection cavity A31. The T-slot 80 is provided on the lower end face of the slider core pulling insert 40 and passes through the two opposite side walls of the slider core pulling insert 40. A wear-resistant pad 120 is removably provided on the side wall of the slider core pulling insert 40 to avoid surface burning after frequent reciprocating motion, thereby ensuring the service life of the slider core pulling insert 40.
