Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, specifically to a demolding device for fixing products with a double slider. Background Technology

[0002] After the product cools, the injection molding machine needs to demold the product. When demolding the product, the front mold slider used to fix the product and form the product needs to be pulled out of the product. However, due to the irregular shape of the surface of the front mold slider and the product structure, when the groove opening of the product where the front mold slider is placed is small, the movement space of the front slider is limited. The existing method cannot pull the front mold slider out of the product and make the product demold smoothly. Utility Model Content

[0003] To address the problem of unsuccessful demolding of existing injection-molded products, this invention provides a demolding device that uses a double slider to fix the product. The specific technical solution of this invention is as follows:

[0004] A demolding device for fixing a product with dual sliders includes: a first telescopic mechanism, a second telescopic mechanism, a third telescopic mechanism, a first slider, a second slider, and a limiting plate. Each of the first, second, and third telescopic mechanisms is equipped with a telescopic rod. The first slider is connected to the telescopic rod of the first telescopic mechanism, the second slider is connected to the telescopic rod of the second telescopic mechanism, and the limiting plate is connected to the telescopic rod of the third telescopic mechanism. The first telescopic mechanism is positioned downwards, and the second telescopic mechanism is positioned laterally. The first and second sliders are fitted together and positioned within the product. The first slider restricts the lateral movement of the second slider, and the limiting plate is positioned above the first slider to restrict its vertical movement.

[0005] Furthermore, the demolding device also includes a support plate, the third telescopic mechanism is arranged laterally, the second telescopic mechanism and the third telescopic mechanism are arranged on the support plate and the third telescopic mechanism is located above the second telescopic mechanism.

[0006] Furthermore, the first slider is a plate-shaped structure, and the surface where the first slider and the second slider of the plate-shaped structure are in contact is a plane, with a limiting part provided at the upper end of the other side.

[0007] Furthermore, the second slider has an L-shaped structure, which includes a vertical part and a horizontal part. One end of the horizontal part is connected to the telescopic rod of the third telescopic mechanism, and the other end is connected to the vertical part. One side of the vertical part is a plane, and the other side is a concave-convex surface. The plane of the vertical part fits with the first slider, and the concave-convex surface fits with the inner wall of the product.

[0008] Furthermore, the limiting plate has a U-shaped structure, and the bottom of the U-shaped limiting plate is connected to the telescopic rod of the third telescopic mechanism.

[0009] Furthermore, the first telescopic mechanism is positioned diagonally downwards.

[0010] Furthermore, the first telescopic mechanism, the second telescopic mechanism, and the third telescopic mechanism are all hydraulic cylinders.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: The demolding device described in this application divides the front slider used for fixing the product and product molding into a first slider and a second slider. When the product is demolded, the first slider is moved up and down to detach from the product, and then the second slider is moved to the middle position of the groove of the product to facilitate the second slider leaving the product, so that the product can be demolded smoothly, effectively improving production efficiency and greatly reducing the difficulty of demolding the product.

[0022] like Figures 1 to 4As shown, a demolding device for fixing a product with two sliders includes: a first telescopic mechanism 1, a second telescopic mechanism 2, a third telescopic mechanism 3, a first slider 4, a second slider 5, and a limiting plate 6. Each of the first telescopic mechanism 1, the second telescopic mechanism 2, and the third telescopic mechanism 3 is equipped with a telescopic rod. The first slider 4 is connected to the telescopic rod of the first telescopic mechanism 1, the second slider 5 is connected to the telescopic rod of the second telescopic mechanism 2, and the limiting plate 6 is connected to the telescopic rod of the third telescopic mechanism 3. The first telescopic mechanism 1 is positioned downwards, and the second telescopic mechanism 2 is positioned horizontally. The first slider 4 and the second slider 5 are fitted together and placed in the product 9. The first slider 4 is used to restrict the horizontal movement of the second slider 5, and the limiting plate 6 is positioned above the first slider 4 to restrict the vertical movement of the first slider 4.

[0023] In one embodiment, the demolding device further includes a support plate 7, the third telescopic mechanism 3 is arranged laterally, the second telescopic mechanism 2 and the third telescopic mechanism 3 are arranged on the support plate 7 and the third telescopic mechanism 3 is located above the second telescopic mechanism 2.

[0024] In one embodiment, the first slider 4 is a plate-shaped structure, and the surface on which the first slider 4 and the second slider 5 fit together is a plane 10, and a limiting part 8 is provided at the upper end of the other side.

[0025] In one embodiment, the second slider 5 has an L-shaped structure, comprising a vertical portion 11 and a horizontal portion 12. One end of the horizontal portion 12 is connected to the telescopic rod of the third telescopic mechanism 3, and the other end is connected to the vertical portion 11.

The flat surface 13 of the vertical portion 11 fits against the first slider 4, and the concave-convex surface 14 fits against the inner wall of the product 9. The contact surfaces of the first slider 4 and the second slider 5 are both flat, reducing friction and facilitating the removal of the product 9 by the first slider.

[0026] In one embodiment, the limiting plate 6 has a U-shaped structure, and the bottom of the U-shaped limiting plate 6 is connected to the telescopic rod of the third telescopic mechanism 3. The two side arms of the U-shaped structure are respectively arranged on the top sides of the first slider 4, which improves the stability of the first slider 4 in the product 9.

[0027] In one embodiment, the first telescopic mechanism 1 is arranged obliquely downward.

[0028] In one embodiment, the first telescopic mechanism 1, the second telescopic mechanism 2, and the third telescopic mechanism 3 are all hydraulic cylinders. Hydraulic cylinders offer high positional and speed accuracy, and the hydraulic system can precisely control their movement using various control elements (such as proportional valves and servo valves). The telescopic mechanisms can also be pneumatic cylinders or other mechanical structures that control the movement of the slider and the limit plate 6.

[0029] After the product is formed in the injection molding machine, such as Figure 4 As shown in Figure 15, during demolding, the third oil cylinder first injects oil to pull back the limit plate 6, unlocking the first slider 4, as follows. Figure 4 As shown in Figure 16; then, oil is injected into the first oil cylinder, pulling the first slider 4, causing the first slider 4 to be pulled out of the product 9 at an angle, making way for the second slider 5, as shown. Figure 4 As shown in Figure 17; then the third oil cylinder outputs oil to push the second slider 5 forward, moving it below the first slider 4, as shown. Figure 4 As shown in Figure 18; then the entire demolding device moves upward, causing the second slider 5 to move upward, and the product 9 completes demolding, as shown in Figure 18. Figure 4 19 shown.

[0030] The demolding device described in this application divides the front slider used to fix the product 9 and the product 9 forming into a first slider 4 and a second slider 5. When the product 9 is demolded, the first slider 4 is moved up and down to detach from the product 9. Then the second slider 5 is moved to the middle position of the groove of the product 9 to facilitate the second slider 5 leaving the product 9, so that the product 9 can be demolded smoothly, effectively improving production efficiency and greatly reducing the demolding difficulty of the product 9.
