AI Technical Summary
When the existing molds are made inclined holes, the slider mechanism causes increased weight of the mold, waste of costs, and difficult to demold.
The inclined pulling mechanism is adopted, through the cooperation of the inclined pulling core and the strong pulling plate, the inclined hole forming is achieved by the movement of the injection molding machine to avoid the use of the slider mechanism.
The efficient completion of inclined hole molding is achieved, and the mold size is basically unchanged, reducing the mold weight and cost.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of molds, in particular to an inclined drawing mechanism. Background Technique
[0002] A mold is a tool used to manufacture parts with specific shapes and sizes. Through mold forming, high-efficiency and low-cost mass production can be achieved. Molds play a crucial role in industrial production.
[0003] Conventionally, when there are inclined holes in the product and it is difficult to demold the mold, we generally use a slider mechanism. The slider mechanism usually increases the weight of the mold by 1 / 3, resulting in waste of cost. Content of the Utility Model
[0004] The purpose of the utility model is to provide an inclined drawing mechanism to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: an inclined drawing mechanism, including a lower plate structure. A bottom plate is arranged at the top of the lower plate structure. A limiting member is arranged on the right side of the bottom plate. The limiting member includes a first protective sleeve. The bottom of the first protective sleeve is fixedly connected with a first fixing seat. The first fixing seat is fixedly connected to the bottom plate. A second protective sleeve is arranged at the top of the first protective sleeve. One side of the second protective sleeve is fixedly connected to the lower plate structure. A strong pulling plate is arranged on one side of the second protective sleeve, the first protective sleeve and the first fixing seat.
[0006] An inclined drawing core is slidably arranged in the inner cavity at the top of the lower plate structure.
[0007] A groove is formed at the front end position on the right side of the lower plate structure. A positioning block is movably arranged in the groove. One side of the positioning block is fixedly connected with a guide rod. A spring is sleeved on the guide rod. One side of the spring contacts the inner wall of the groove of the lower plate structure, and the other end of the spring is fixedly connected with the positioning block.
[0008] Compared with the prior art, the beneficial effects of the utility model are:
[0009] By opening the upper and lower plates of the injection molding machine, driving the delayed movement of the strong pulling plate and the elastic block baffle, the inclined drawing core is withdrawn from the product, and the injection molding of the inclined hole of the product is completed. The structure of the utility model is simple, the space utilized is small, the size of the mold is basically not increased, and the practicability is improved. Brief Description of the Drawings

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0017] Please refer to Figures 1-5 , the present utility model provides a technical solution: an oblique core-pulling mechanism, including a lower plate structure 1, a bottom plate 2 is arranged on the top of the lower plate structure 1, a limiting member 4 is arranged on the right side of the bottom plate 2, the limiting member 4 includes a first protective sleeve 401, a first fixed seat 404 is fixedly connected to the bottom of the first protective sleeve 401, the first fixed seat 404 is fixedly connected to the bottom plate 2, a second protective sleeve 402 is arranged on the top of the first protective sleeve 401, one side of the second protective sleeve 402 is fixedly connected to the lower plate structure 1, a strong pulling plate 403 is arranged on one side of the second protective sleeve 402, the first protective sleeve 401 and the first fixed seat 404, and the strong pulling plate 403 is fixedly connected to the upper plate structure (not shown in the figure).
[0018] An oblique core-pulling 3 is slidably arranged in the inner cavity of the top of the lower plate structure 1.
[0019] A groove is formed at the front end of the right side of the lower plate structure 1, and a positioning block 5 is movably arranged in the groove. A guide rod 6 is fixedly connected to one side of the positioning block 5, a spring 7 is sleeved on the guide rod 6, one side of the spring 7 contacts the inner wall of the groove of the lower plate structure 1, and the other end of the spring 7 is fixedly connected to the positioning block 5. The positioning block 5 can pop out through the spring 7.
[0020] During use, the upper plate structure and the lower plate structure 1 are opened by an injection molding machine, driving the delayed movement of the strong pulling plate 403 and the positioning block 5. The strong pulling plate 403 is stuck by the positioning block 5, the lower plate structure 1 moves, while the following bottom plate does not move, and the oblique core-pulling is fixed on the lower plate structure 1 without moving, so that the oblique core-pulling withdraws from the product.
