Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and specifically to a slider limit switch protection structure. Background Technology

[0002] In the injection molding process, existing limit switches are directly installed on the mold frame, making their position adjustable. This necessitates disassembly and reinstallation for adjustment, which is cumbersome. Limit control is crucial for preventing collision damage. Traditional limit switches are often single, independent structures, leading to problems such as cumbersome installation, susceptibility to signal interference, and poor compatibility with different devices. Furthermore, traditional limit switches suffer from messy wiring, difficult debugging, and poor stability. Utility Model Content

[0003] The purpose of this utility model is to provide a sliding limit switch protection structure, which aims to solve the problems of existing limit switches such as inability to adjust, cumbersome installation, susceptibility to signal transmission interference, and poor compatibility with different devices.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] This utility model designs a protection structure for a slider limit switch, which includes the following structural features:

[0006] A punch has a first side and a second side opposite to each other, and a slider groove that communicates with the first side is also provided thereon.

[0007] A slider, which is disposed in the slider groove and has a degree of freedom to slide in the Y-axis direction;

[0008] The slider connecting rod has one end connected to the slider in the Y-axis direction and the other end passing through the second side surface, forming a structure that slides through the punch.

[0009] A hydraulic cylinder is mounted on the punch and is also connected to the end of the slider connecting rod to drive the slider to slide in the Y-axis direction;

[0010] A limit switch bracket is connected to the second side and has a degree of freedom for adjustment in the X-axis direction (specifically, the position of the limit switch bracket in the X-axis direction on the punch is adjusted).

[0011] Two limit switches are provided, each connected to the limit switch bracket and having a degree of freedom to adjust the distance in the Y-axis direction. The limit switches are used to control the operation / stop of the hydraulic cylinder.

[0012] And a limit switch is provided on the slider connecting rod. The limit switch is also located between two limit switches, and its two ends in the Y-axis direction are respectively used to contact the two limit switches (that is, after the limit switch contacts the limit switches, the cylinder stops running).

[0013] Furthermore, a slider limit switch protection structure is provided: the protection structure further includes an adapter block and a limiting rod; the adapter block is connected to the slider connecting rod, the end of the limiting rod is connected to the adapter block and extends naturally along the Y-axis direction, and the limiter is disposed on the limiting rod.

[0014] Furthermore, a slider limit switch protection structure is provided: the limiter is slidably sleeved on the limit rod and fixed by a locking bolt.

[0015] Furthermore, a slider limit switch protection structure is provided: the protection structure further includes a support block disposed on the second side and extending along the Y-axis direction for supporting the sliding of the adapter block thereon.

[0016] Furthermore, a slider limit switch protection structure is provided: the protection structure further includes a cylinder bracket, which is disposed on the punch, the cylinder is disposed on the cylinder bracket, and the output end of the cylinder is connected to the end of the slider connecting rod.

[0017] Specifically, the hydraulic cylinder drives the slider connecting rod to slide in the Y-axis direction, thereby causing the slider to slide in the Y-axis direction.

[0018] Furthermore, a slider limit switch protection structure is provided: the limit switch bracket is provided with a long row of grooves extending in the X-axis direction, and the limit switch bracket is connected to the second side of the punch by a first adjusting bolt provided in the long row of grooves.

[0019] Furthermore, a slider limit switch protection structure is provided: the limit switch bracket is also provided with a number of fixing holes arranged in the Y-axis direction, and the limit switch is connected to the limit switch bracket through the fixing holes and the second adjusting bolt.

[0020] The beneficial effects of this utility model are:

[0021] This utility model designs a slider limit switch protection structure. Through the structural arrangement of limit switches and limiters, the limiter is positioned between two limit switches, and the distance between the two limit switches determines the slider's travel range, allowing for precise control of the travel position. Simultaneously, the spacing between the limit switches in the Y-axis direction is adjustable, which allows for adjustment of the slider's travel range, better achieving travel control and preventing collision damage.

[0022] This utility model designs a slider limit switch protection structure. By setting an X-axis long row of grooves on the limit switch bracket, the position of the limit switch can be adjusted in cooperation with the first adjusting bolt, providing secondary protection for the limit switch. This switch protection structure has simple and convenient position adjustment and fixing functions, and is highly practical.

[0023] This utility model designs a slider limit switch protection structure, which allows the position of the limit switch bracket in the X-axis direction to be adjusted by loosening the first adjusting bolt, and then fixed by tightening the first adjusting bolt. This not only achieves flexible adjustment of the limit switch position but also simplifies installation, solving the problems of existing limit switches being unable to adjust position and having cumbersome installation. Furthermore, this slider limit switch protection structure has no messy wiring, making installation simple. Attached Figure Description

[0031] Example 1

[0032] like Figures 1-2 As shown, a slider limit switch protection structure includes the following features:

[0033] The punch 1 has a first side 11 and a second side 12 opposite to each other, and a slider groove 13 that passes through the first side 11 is also provided thereon.

[0034] Slider 2 is set in slider groove 13 and has the degree of freedom to slide in the Y-axis direction;

[0035] The slider connecting rod 3 has one end connected to the slider 2 in the Y-axis direction and the other end passing through the second side 12, forming a structure that slides through the punch 1. The slider connecting rod 3 is also connected to the adapter block 8, and the adapter block 8 is connected to the limiting rod 9 that extends naturally along the Y-axis direction.

[0036] The hydraulic cylinder 4 is mounted on the hydraulic cylinder bracket 10, which is mounted on the second side 12 of the punch 1. The output end of the hydraulic cylinder 4 is also connected to the end of the slider connecting rod 3 to drive the slider 2 to slide in the Y-axis direction.

[0037] The limit switch bracket 5 is provided with an elongated groove 51 extending in the X-axis direction and a number of fixing holes arranged in the Y-axis direction. The limit switch bracket 5 is connected to the second side 12 of the punch 1 by a first adjusting bolt 15 provided in the elongated groove 51, thereby forming a structure in which the limit switch bracket 5 can be adjusted along the X-axis direction on the second side 12, thereby realizing the function of adjustable limit switch position.

[0038] Limit switches 6, which are configured in pairs, are respectively connected to the limit switch bracket 5 through the fixing hole and the second adjusting bolt 16 (the fixing hole makes the spacing of the limit switches 6 in the Y-axis direction adjustable). The limit switches 6 can be used to control the operation / stop of the hydraulic cylinder 4.

[0039] And limit switch 7, which is slidably sleeved on limit rod 9 and fixed by locking bolt 14. Limit switch 7 is located between two limit switches 6. Its two ends in the Y-axis direction are respectively used to contact the two limit switches 6. When the travel reaches the two ends of limit switch 7, limit switch 7 contacts limit switch 6 and triggers limit switch 6. After limit switch 6 is triggered, the oil cylinder 4 is disconnected and stops moving, thereby preventing collision with the mold and realizing the protection function.

[0040] Preferably, a support block 17 extending along the Y-axis is also provided on the second side 12. The adapter block 8 is slidably engaged with the support block 17, and the support block 17 provides support to the adapter block 8, thereby enhancing structural stability.

[0041] Specifically, in the slider travel switch protection structure of Embodiment 1, the hydraulic cylinder 4 on the punch 1 is activated, driving the slider connecting rod 3 and the slider 2 to move, generating travel. The movement of the slider connecting rod 3 is transmitted to the limit rod 9 and the limit switch 7 through the adapter block 8, causing them to also generate corresponding travel. The limit switch 7 is mounted on the limit rod 9 by locking bolts 14, and the travel switch 6 is mounted on the travel switch bracket 5. When the limit switch 7 moves to both ends with the travel, it triggers the travel switch 6. After the travel switch 6 is triggered, it performs the hydraulic cylinder protection function, causing the hydraulic cylinder 4 to disconnect and stop moving, thereby preventing mold collision and achieving the protection function.

[0042] The above-described preferred embodiments of this utility model are for illustrative purposes only and are not intended to limit the scope of this utility model. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
