Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a mold opening device for producing textile machine parts molds. Background Technology

[0002] A textile machine is a mechanical device used to process fibers or yarns into textiles. It is one of the core pieces of equipment in the textile industry. A textile machine is assembled from a variety of parts, some of which are made of metal and some of which are made of plastic. Plastic parts are widely used because of their advantages such as lightweight, corrosion resistance and low cost. In the production process of plastic parts, injection molds are used to achieve one-time molding. During use, mold opening devices are used to separate the molds and then remove the products.

[0003] Currently, existing mold-making devices typically use bolts to fix the fixed mold or moving mold during installation. However, before fixing the fixed mold and moving mold, they need to be aligned. For some larger plastic parts, the molds used are also larger and heavier, making it difficult for workers to quickly align the fixed mold and moving mold in a short time, which seriously affects the production efficiency of plastic parts. Utility Model Content

[0004] The purpose of this utility model is to provide a mold opening device for producing textile machine parts molds, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A mold opening device for producing textile machine parts molds includes a mold frame, a fixed mold and a moving mold. The mold frame is slidably connected to a moving mechanism that is fixedly connected to the moving mold. The bottom of the mold frame is provided with four centering and fixing mechanisms arranged in a rectangular pattern. Mounting plates are fixedly connected to the opposite sides of the fixed mold and the moving mold. The mounting plate located at the fixed mold has through holes on its side corresponding to the centering and fixing mechanisms.

[0007] The centering and fixing mechanism includes an L-shaped plate that slides on the bottom surface inside the mold frame. A screw is screwed through the top surface of the L-shaped plate. The bottom end of the screw is rotatably connected to a moving block that abuts against the L-shaped plate at a corresponding position. The bottom surface of the moving block is fixedly connected to a plug that inserts into a through hole at a corresponding position.

[0008] Furthermore, the mold frame consists of a rectangular shell, four sliding rods, and a top plate, with the four sliding rods arranged in a rectangular pattern and fixedly connected between the rectangular shell and the top plate.

[0009] Furthermore, the top surface of the rectangular shell has four sliding holes arranged in a rectangular pattern. The L-shaped plate slides within the corresponding sliding holes. A spiral frame is fixedly connected inside the rectangular shell. A lead screw that is screwed through and engaged with the L-shaped plate at the corresponding position is rotatably connected between the spiral frame and the opposite side of the rectangular shell.

[0010] Furthermore, one end of the lead screw passes through the spiral frame and is fixedly connected to a bevel gear, with two adjacent bevel gears meshing for transmission; the other end of the lead screw passes through the rectangular shell and is fixedly connected to a rotating block.

[0011] Furthermore, the moving mechanism includes a moving plate that is slidably connected between four slide rods and detachably connected to the moving mold, and the top surface of the moving plate is detachably connected to two symmetrical hydraulic cylinders that are fixed through the top plate.

[0012] Furthermore, both ends of the top surface of the movable plate are fixedly connected to mounting blocks, and the output end of the hydraulic cylinder is fixedly connected to a connecting block that can be detachably connected to the mounting block at the corresponding position.

[0013] Furthermore, both ends of the two opposing sides of the movable plate are fixedly connected to sliders that slide through the corresponding sliding rods.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By bringing four L-shaped plates together, the centers of the fixed mold and the moving mold are quickly aligned with the center of the bottom of the mold frame. Then, by rotating the screw, the insert block is inserted into the corresponding through hole, which can quickly fix the fixed mold. Therefore, there is no need for frequent manual adjustment and alignment of the fixed mold and the moving mold, which can save time and improve the production efficiency of the product.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 - Figure 5 In this embodiment of the present invention, a mold opening device for a textile machine parts production mold includes a mold frame 1, a fixed mold 3, and a moving mold 4. The mold frame 1 is slidably connected to a moving mechanism 2 that is fixedly connected to the moving mold 4. The bottom of the mold frame 1 is provided with four rectangularly distributed centering and fixing mechanisms 5. The sides of the fixed mold 3 and the moving mold 4 that are opposite to each other are fixedly connected to mounting plates 31. The side of the mounting plate 31 located at the fixed mold 3 is provided with through holes 32 corresponding to the centering and fixing mechanisms 5. The centering and fixing mechanism 5 includes an L-shaped plate 51 that slides on the bottom surface of the mold frame 1. A screw 52 is screwed through the top surface of the L-shaped plate 51. The bottom end of the screw 52 is rotatably connected to a moving block 53 that abuts against the L-shaped plate 51 at the corresponding position. The bottom surface of the moving block 53 is fixedly connected to an insert block 54 that inserts into the through hole 32 at the corresponding position.

[0024] Specifically, since the fixed mold 3 and the moving mold 4 are joined together before installation, during installation, the fixed mold 3 and the moving mold 4 are first placed at the inner bottom of the mold frame 1. Then, the four L-shaped plates 51 are moved towards the center to make the center of the fixed mold 3 and the center of the bottom of the mold frame 1 collinear. Then, the screw 52 is rotated to move the insert 54 downwards until the insert 54 is inserted into the corresponding through hole 32. At this time, the fixed mold 3 is firmly fixed at the inner bottom of the mold frame 1. Since the fixed mold 3 and the moving mold 4 are joined together, the center of the moving mold 4 and the center of the inner bottom of the mold frame 1 are collinear. Then, the moving mechanism 2 moves down and comes into contact with the moving mold 4. The moving mold 4 is fixed to the bottom of the moving mechanism 2 by bolts. Then, the moving mechanism 2 drives the moving mold 4 to close or open the mold with the fixed mold 3. The device moves the four L-shaped plates 51 towards the middle, so that the center of the fixed mold 3 and the moving mold 4 are quickly aligned with the center of the bottom of the mold frame 1. Then, the screw 52 rotates to insert the insert block 54 into the through hole 32 at the corresponding position, so that the fixed mold 3 can be quickly fixed. Therefore, there is no need for frequent manual adjustment and alignment of the fixed mold 3 and the moving mold 4, which can save time and improve the production efficiency of the product.

[0025] Example 1

[0026] like Figure 5 As shown, in this embodiment, the mold frame 1 consists of a rectangular shell 11, four sliding rods 12, and a top plate 13. The four sliding rods 12 are fixedly connected between the rectangular shell 11 and the top plate 13 in a rectangular distribution. The top surface of the rectangular shell 11 has four sliding holes in a rectangular distribution. The L-shaped plate 51 slides in the corresponding sliding holes. A U-shaped frame 14 is fixedly connected inside the rectangular shell 11. A lead screw 55 is rotatably connected between the U-shaped frame 14 and the opposite side of the rectangular shell 11 and is screwed through the L-shaped plate 51 at the corresponding position. One end of the lead screw 55 passes through the U-shaped frame 14 and is fixedly connected to a bevel gear 56. Two adjacent bevel gears 56 mesh and drive each other. The other end of the lead screw 55 passes through the rectangular shell 11 and is fixedly connected to a rotating block.

[0027] In this embodiment, the operator uses a tool to rotate one of the lead screws 55. Since the two adjacent bevel gears 56 mesh and drive each other, all four lead screws 55 will rotate simultaneously. The rotating lead screw 55 can move the L-shaped plate 51 at the corresponding position toward the center of the rectangular shell 11, thereby correcting the fixed mold 3 that is off-center from the center of the rectangular shell 11, so that the center of the fixed mold 3 is on the same straight line as the center of the rectangular shell 11. This allows the fixed mold 3 to be quickly aligned with the moving mold 4, avoiding the situation where the moving mold 4 deviates from the fixed mold 3 when it is installed.

[0028] Example 2

[0029] like Figure 3As shown, in this embodiment, the moving mechanism 2 includes a moving plate 21 that is slidably connected between four slide rods 12 and detachably connected to the moving mold 4. The top surface of the moving plate 21 is detachably connected to two symmetrical hydraulic cylinders 22 that are fixed through the top plate 13. Mounting blocks 23 are fixedly connected to both ends of the top surface of the moving plate 21. The output end of the hydraulic cylinder 22 is fixedly connected to a connecting block 24 that is detachably connected to the mounting block 23 at the corresponding position. The two opposite sides of the moving plate 21 are fixedly connected to sliders 25 that slide through the slide rods 12 at the corresponding positions.

[0030] In this embodiment, the moving plate 21 can be moved down by driving the two hydraulic cylinders 22 until the moving plate 21 contacts the mounting plate 31 of the moving mold 4. Then, the mounting plate 31 is fixed to the bottom surface of the moving plate 21 by bolts. Since the moving mold 4 is still joined with the fixed mold 3 when it is fixed, the moving mold 4 can still be perfectly joined with the fixed mold 3 when it moves down with the moving plate 21 after installation, avoiding scratches.
