[0002] Molds refer to various molds and tools used in industrial production to obtain desired products through injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. They are widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The sliding block refers to the slider insert part in the mold. This part moves linearly with the opening and closing of the mold. It can be used to assist in the molding of the product. At the same time, it separates from the product when the mold is opened to avoid interference when the product is taken out.

[0003] Some injection mold sliding mechanisms require screws to connect to sliding blocks on the template during installation. When damaged, they require a long time to replace, affecting the use of the injection mold. Therefore, this does not meet the current requirements. To address this, we have proposed a new type of quick-assembly and disassembly sliding mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of quick-assembly and disassembly sliding mechanism to solve the problems mentioned in the background art, such as the need to use screws to connect the sliding mechanism of the injection mold to the sliding block on the template during installation, the need to spend a long time to replace it when damaged, and the impact on the use of the injection mold.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel quick-assembly and disassembly sliding mechanism, comprising a fixed mold, a moving mold plate, and a product. The surface of the fixed mold is provided with a slider mounting groove, the inner wall of the slider mounting groove is provided with two guide grooves, a sliding slider is slidably mounted on the inner side of the slider mounting groove, an inclined guide post hole is provided through the inside of the sliding slider, and an ejector pin is also slidably inserted through the inside of the sliding slider. A molding insert is detachably mounted on the top of the ejector pin.

[0006] Preferably, the bottom of the moving template is detachably fitted with a limit block and an inclined guide post.

[0007] Preferably, the sliding slider includes a slider body, the two sides of which slide in contact with the inner wall of the slider mounting groove, and both sides of the slider body are provided with a storage groove, and a rotating reset plate is rotatably installed on the inner side of the storage groove.

[0008] Preferably, the rotating reset plate is L-shaped and its bottom end is slidably engaged with the inside of the guide groove. A spring is provided between the bottom end of the rotating reset plate and the end of the guide groove. A cylindrical protrusion is provided at the top end of the rotating reset plate, and the cylindrical protrusion is rotatably inserted into the inside of the slider body.

[0009] Preferably, the storage slot has a sliding groove inside, and a support block is slidably installed on the inner side of the sliding groove.

[0010] Preferably, one end of the support block slides in contact with the side of the rotating reset plate, and the outer surface of the rotating reset plate is provided with a reserved groove, the height of which is the same as the thickness of the support block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] When the slide block is damaged and needs to be replaced, this utility model only requires moving the support block upward to the height of the reserved slot, and then rotating the rotary reset plate inward into the receiving slot until the end of the support block enters the reserved slot and the rotary reset plate is parallel to the side of the slide block body. At this time, the slide block body is separated from the fixed mold, realizing the quick disassembly or installation of the slide block as a whole, saving the time required for mold maintenance and not affecting the use of the mold.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figures 1 to 4As shown, a novel quick-assembly and disassembly sliding mechanism includes a fixed mold 1, a moving mold plate, and a product 9. The bottom of the moving mold plate is detachably mounted with a limit block 5 and an inclined guide post 6. The surface of the fixed mold 1 is provided with a slider mounting groove 3. The inner wall of the slider mounting groove 3 is provided with two guide grooves 10. A sliding slider 2 is slidably mounted on the inner side of the slider mounting groove 3. An inclined guide post hole 4 is provided through the inside of the sliding slider 2. The inclined guide post 6 is connected to the sliding slider 2 through the inclined guide post hole 4 to realize the linear displacement of the sliding slider 2.

[0020] Inside the sliding block 2, ejector pins 8 are also slidably inserted. A molding insert 7 is detachably installed on the top of the ejector pin 8. The sliding block 2 drives the movement of the ejector pin 8 and the molding insert 7, changing the position of the molding insert 7. This allows the molding insert 7 to cooperate with the cavities on the fixed mold 1 and the moving mold plate to form the product. The molding insert 7 also separates the product from the inner wall of the cavity on the fixed mold 1 and the moving mold plate, thus achieving automatic demolding of the product.

[0021] The sliding block 2 includes a slider body 21. The two sides of the slider body 21 slide in contact with the inner wall of the slider mounting groove 3. Both sides of the slider body 21 are provided with a receiving groove 22. A rotating reset plate 23 is rotatably installed on the inner side of the receiving groove 22. The rotating reset plate 23 is L-shaped and its bottom end is slidably engaged with the inner side of the guide groove 10. A spring is provided between the bottom end of the rotating reset plate 23 and the end of the guide groove 10. A cylindrical protrusion is provided at the top of the rotating reset plate 23. The cylindrical protrusion is rotatably inserted into the inside of the slider body 21. The bottom end of the rotatable rotating reset plate 23 is inserted into the inside of the guide groove 10. After the inclined guide post 6 moves upward, the sliding block 2 moves as a whole through the spring provided inside the guide groove 10. Thus, the product is separated from the inner wall of the cavity by the molding insert 7.

[0022] The storage slot 22 has a sliding groove 26 inside, and a support block 25 is slidably installed on the inner side of the sliding groove 26. One end of the support block 25 is in sliding contact with the side of the rotating reset plate 23. The outer surface of the rotating reset plate 23 has a reserved groove 24. The height of the reserved groove 24 is the same as the thickness of the support block 25. The support block 25 is used to lock the position of the rotating reset plate 23 after rotation, so as to prevent the rotating reset plate 23 from detaching from the guide groove 10. The presence of the reserved groove 24 ensures that after the support block 25 moves up, the rotating reset plate 23 can rotate into the storage slot 22.

[0023] The hydraulic device of the mold drives the moving platen to move downward. After the moving platen moves downward, the inclined guide post 6 enters the top of the inclined guide post hole 4 and squeezes the sliding block 2, causing the sliding block 2 to drive the ejector pin 8 and the molding insert 7 to move towards the middle of the fixed mold 1 until the moving platen contacts the fixed mold 1. At this time, the molding insert 7 enters the cavity between the fixed mold 1 and the moving platen, and the injection molding operation is performed. After the product 9 is injected, the mold opens. After opening, the inclined guide post 6 exits from inside the inclined guide post hole 4. At this time, the spring between the rotary reset plate 23 and the guide slide 10 returns to its elasticity and pushes the rotary reset plate 23, so that the slider body 21 is reset under the action of the rotary reset plate 23, separating the ejector pin 8, the molding insert 7 and the product 9 outside the molding insert 7 from the inner wall of the cavity, realizing the automatic demolding of the product 9, saving manual material handling time and improving the production efficiency of the mold. Finally, the ejector pin 8 drives the molding insert 7 and the product 9 to move upward, completely separating the product 9 from the mold. The product 9 can then be removed using the mechanical arm that comes with the mold.
