Description
Technical Field

[0002] A mold is a tool used to manufacture or process items. It is made up of various parts. These parts can be metal, plastic or other materials. The main function of the mold is to shape the material into a specific shape and size.
[0003] After searching the Chinese patent publication number: CN206297101U, a variable-angle mold core pulling structure is disclosed, which is characterized in that it includes a horseshoe, a connecting rod arranged on the horseshoe and a slider arranged at the end of the connecting rod. The connecting rod and the horseshoe are movably connected, and a spring seat is provided at the end of the connecting rod, and a spring is provided in the spring seat.
[0004] In order to solve the problem that the core cannot be directly pulled out like a straight-through joint, the above patent uses a variable-angle mold core-pulling structure. When the mold core is pulled out, the horseshoe follows the curvature of the product, making the horseshoe straighten and achieving the effect of smooth core pulling.
[0005] However, in reality, when the product to be produced by the mold has a complex geometric shape or inner cavity, the traditional linear core pulling may not be able to effectively remove the core in the mold. Multi-angle adjustment can ensure that the core pulling process better adapts to the product shape, thereby reducing the risk of jamming.
[0006] Therefore, the utility model provides a mold core-pulling structure with a variable angle. Utility Model Content

[0010] As a preferred embodiment, the adaptive component includes a positioning column, a spring is sleeved on the outer side of the positioning column, and an active sliding column is fixedly connected to the interior of the fixing column.
[0011] The technical effect of adopting the above technical solution is that the core pulling direction can be adjusted between the vertical and horizontal directions to adapt to the inner cavity shape of the product. This inclined design makes the core pulling action more in line with the geometric shape of the product, reducing friction and the risk of jamming during the core pulling process.
[0012] As a preferred embodiment, one end of the stop block is rotatably connected to the angle adjustment plate.
[0013] The technical effect of adopting the above technical solution is: to fine-tune the angle during the core pulling process to better adapt to the complex geometric shape of the product.
[0014] As a preferred embodiment, the angle adjustment plate is 45 degrees and tilted toward the push plate.
[0015] The technical effect of adopting the above technical solution is that the inclined angle adjustment plate can make the core pulling action smoother and reduce the jamming phenomenon during the core pulling process.
[0016] As a preferred embodiment, the outer side of the positioning column is slidably connected to the interior of the hollow sliding column.

[0024] Compared with the prior art, the advantages and positive effects of the present invention are:
[0025] The utility model provides a sliding connection of a push plate in the adjustment assembly and provides a linear driving force for core pulling. The push plate is connected to a hollow slide column, and the outer side of the hollow slide column is rotatably connected to the angle adjustment plate, so that the core pulling direction can be flexibly adjusted between the vertical and horizontal directions. This design can reduce the friction and the risk of jamming during the core pulling process when facing the complex inner cavity shape of the product, thereby increasing the adaptability to complex-shaped products, thereby effectively solving the problem of difficulty in removing the core from the mold;
[0026] The utility model provides a restoring force when the fixing column is pulled backward by the re-fixing column, pulling the push plate backward to ensure that the push plate quickly returns to the initial position after the core pulling is completed, and is ready for the next operation. In addition, through the design of four positioning columns and springs, each is separately connected to the stop block, so that when the stop block contacts the inner wall of the product, it can automatically adapt to the uneven shape.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example
[0036] like Figure 1 - Figure 3 As shown, this embodiment provides a technical solution: a variable-angle mold core pulling structure, comprising a fixed column 1, an adjustment component 2 is slidably connected to the interior of the fixed column 1, and an adaptive component 3 is fixedly connected to the interior of the fixed column 1;
[0037] The adjusting component 2 includes a push plate 21, one end of which is slidably connected to the fixed column 1, and one end of the push plate 21 is fixedly connected to a hollow sliding column 22. The outer side of the hollow sliding column 22 is rotatably connected to an angle adjustment plate 23, and the angle adjustment plate 23 is 45 degrees and inclined toward the push plate 21. The internal sliding connection of the fixed column 1 is a limited slider 24, and one end of the limited slider 24 is fixedly connected to a stop block 25. One end of the stop block 25 is rotatably connected to the angle adjustment plate 23. The fixed column 1 serves as the base of the entire core pulling structure and provides a stable installation platform for other components. One end of the push plate 21 in the adjusting component 2 is slidably connected in the fixed column 1, and the other end is fixedly connected to the hollow sliding column 22. This design allows the push plate 21 to move flexibly inside the fixed column 1, providing a linear driving force for the core pulling action. As the hollow slide 22 slides, it ensures that the hollow slide 22 maintains a stable linear motion during the sliding process. The angle adjustment plate 23 is designed to be 45 degrees and tilted toward the push plate 21, so that the core pulling direction is adjusted between the vertical and horizontal directions to adapt to the inner cavity of the product. This tilted design makes the core pulling action more fit the geometric shape of the product, reducing the friction and jamming risk during the core pulling process. The design of the limit slider 24 and the block 25 not only provides a limiting function for the core pulling action, ensuring the accuracy and repeatability of the core pulling action, the angle adjustment plate 23 on the hollow slide 22 will drive the block 25 to make a fine adjustment. When the block 25 moves, the design of the limit slider 24 can make the block 25 stably perform linear motion on the fixed column 1 until it contacts the product. Example
[0038] like Figure 1 and Figure 4As shown: the adaptive component 3 includes a positioning column 31, the outer side of the positioning column 31 is slidably connected to the inside of the hollow sliding column 22, and a spring 32 is sleeved on the outer side of the positioning column 31. When the fixed column 1 is pulled backward, the internal spring 32 will pull the push plate 21 to the rear side under the tension. One end of the spring 32 is fixedly connected to the fixed column 1, and the other end of the spring 32 is fixedly connected to the push plate 21. An active sliding column 33 is fixedly connected to the inside of the fixed column 1, and the inside of the push plate 21 is slidably connected to the active sliding column 33. The positioning column 31 is slidably connected to the inside of the hollow sliding column 22, so that the positioning column 31 can be in the hollow sliding column The column 22 slides freely inside to adapt to the core pulling needs of different depths. The design of the spring 32 provides a restoring force to ensure that after the core pulling action is completed, the push plate 21 can quickly return to the initial position to prepare for the next core pulling action. The active sliding column 33 provides a stable guide to ensure that the linear motion of the push plate 21 does not deviate from the predetermined trajectory. Secondly, since there are four positioning columns 31 and springs 32, and each is separately connected to the block 25, when the block 25 contacts the inner wall of the product and there are uneven places, it can be automatically adjusted under the action of the spring 32 to achieve the best fit.
