[0049] The present invention provides a multi-stage slider demoulding device 100 .

[0050] like Figures 1 to 4 As shown, a multi-stage slider demoulding device 100, the multi-stage slider demoulding device 100 comprises: a first slider 10, the first slider 10 is provided with a core-pulling surface D, the first slider 10 is also provided with a tunnel hole penetrating the first slider 10, the first opening of the tunnel hole is located on the core-pulling surface D, and the tunnel hole is inclined; a tunnel slider 20, the tunnel slider 20 is slidably arranged in the tunnel hole, the tunnel slider 20 is provided with a pipeline mold cavity A, the tunnel slider 20 is provided with an injection port (not shown), the injection port is communicated with the second opening of the tunnel hole, and the second opening The height of the core-pulling slider assembly 30 is less than the height of the first orifice, and the pipeline mold cavity A is connected to the injection port; the core-pulling slider assembly 30 is arranged on the first slider 10 and abuts against the core-pulling surface D, the core-pulling slider assembly 30 is connected to the side of the tunnel slider 20 away from the injection port, and the tunnel slider 20 can slide upwardly at an angle relative to the core-pulling slider assembly 30; wherein, when the core-pulling slider assembly 30 is away from the core-pulling surface D, the tunnel slider 20 moves upwardly at an angle relative to the core-pulling slider assembly 30, and at the same time moves in a direction away from the injection port.

[0051] In this embodiment, a tunnel hole is provided inside the first slider 10. The tunnel hole is a straight hole. The tunnel hole passes through the first slider 10 and is tilted. For example, a mold groove is provided on the left side of the first slider 10. The inclination direction of the tunnel hole is tilted from the lower left to the upper right, that is, the first opening is located at the upper right, and the second opening is located at the lower left. The tunnel hole is connected to the mold groove, and the axis of the tunnel hole is set at an angle to the core pulling surface. A tunnel slider 20 is slidably set in the tunnel hole. A pipeline mold cavity A is provided inside the tunnel slider 20, and an injection port is provided at one end of the tunnel slider 20 facing the mold groove. The injection port is connected to the second opening, and the injection port is connected to the tunnel hole and also to the mold groove. In order to form a complete injection molding cavity, a mold clamping piece (not shown) is also required. The surface of the mold clamping piece is also provided with a mold groove. The mold clamping piece is assembled with the first slider 10 and mold clamping is achieved to form a complete injection molding cavity. After the injection liquid with strong pressure is injected, the injection liquid fills the injection cavity and the pipeline cavity A, and the drainage pipe of the product is formed in the pipeline cavity A, and is integrally formed with the product in the injection cavity. After the products are cooled, the mold parts are opened for demoulding. In this process, in order to reduce the process of core pulling and demoulding, the present invention adopts a core pulling slider assembly 30, which is arranged on the first slider 10, and the core pulling slider assembly 30 is in contact with the core pulling surface D, and is connected to the side of the tunnel slider 20 away from the injection port, so that the tunnel slider 20 can be moved by driving the core pulling slider assembly 30. The core pulling slider assembly 30 can also slide relative to the tunnel slider 20. For example, a T-shaped slide groove or a dovetail slide groove can be opened on the tunnel slider 20. The T-shaped slide groove or the dovetail slide groove can be tilted, and the tilting direction can be the same as the tilting direction of the tunnel hole, that is, the angle range in the same quadrant, or the same tilting angle. The core pulling slider assembly 30 is slidably arranged in the T-shaped slide groove or the dovetail slide groove. When the core-pulling slider assembly 30 is away from the core-pulling surface D ( Figure 1 In the F0 direction in the figure), the tunnel slider 20 moves upwardly relative to the core-pulling slider assembly 30 to prevent the tunnel slider 20 from being stuck in the tunnel hole, and at the same time, the tunnel slider 20 moves away from the injection port. For example, the injection port is located on the left side of the first slider 10, and the core-pulling slider assembly 30 moves to the right, driving the tunnel slider 20 to generate a rightward force. At this time, since the tunnel slider 20 can slide upwardly relative to the core-pulling slider assembly 30, the tunnel slider 20 decomposes the force received into an oblique upward force, so that the tunnel slider 20 moves away from the injection port to achieve core-pulling demoulding.

[0052] Therefore, the present invention connects the core pulling slider assembly 30 to the side of the tunnel slider 20 away from the injection port, and the tunnel slider 20 can slide upward at an angle relative to the core pulling slider assembly 30. When the core pulling slider assembly 30 moves in a direction away from the tunnel hole, the tunnel slider 20 moves upward at an angle relative to the core pulling slider assembly 30 and moves in a direction away from the injection port at the same time, thereby achieving rapid core pulling and demolding, reducing the core pulling and demolding process, and also reducing the cost of producing the mold.

When the core pulling mechanism 32 is forced to slide in the direction away from the tunnel hole, the traction part 212 is always connected with the core pulling mechanism 32, but the tunnel slider 20 still moves obliquely upward relative to the core pulling mechanism 32, so as to facilitate the injection part 211 to slide in the tunnel hole.

[0055] Specifically, the first slide groove is vertically arranged. In this embodiment, in order to facilitate the injection molding part 211 to quickly detach from the tunnel hole, the first slide groove can be vertically arranged, and when the core pulling mechanism 32 is forced to slide in a direction away from the tunnel hole, the tunnel slider 20 moves upward relative to the core pulling mechanism 32, which is conducive to increasing the height between the tunnel slider 20 and the core pulling mechanism 32.

In the initial state, the adjustment rod 322 is inclined toward the direction of the core pulling surface D, that is, inclined from the lower right to the upper left. When the adjustment rod 322 rotates in the direction away from the core pulling surface D, the second slider 321 is forced to move away from the core pulling surface D, that is, slide to the right, driving the traction part 212 to move obliquely upward along the oblique slide groove B, and at the same time move upward relative to the second slider 321, so that the drainage pipe in the pipeline mold cavity A is separated from the pipeline mold cavity A.

In the initial state, a limited gap is left between the stopper 323 and the second slider 321. During the core pulling and demolding, when the product in the pipe mold cavity A is separated from the pipe mold cavity A, one end of the second slider 321 away from the traction part 212 abuts against the stopper 323, thereby limiting the displacement of the second slider 321.
