Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically an injection mold frame that facilitates demolding. Background Technology

[0002] Injection molds, also known as injection molds or injection molding machines, are a type of combined plastic mold, mainly composed of a moving mold and a fixed mold. During injection molding, the moving mold and the fixed mold close to form the gating system and cavity. When the mold opens, the moving mold and the fixed mold separate to remove the plastic product. The structure of the mold is usually determined according to the structure of the plastic product and the molding method, and its working principle is similar to that of a syringe syringe.

[0003] Regarding the above and existing related technologies: In the production of plastic products, injection molds are common equipment. After molding, the product needs to be ejected by a mechanism inside the mold. Most products can be demolded by their own ejection mechanism. However, since only one type of ejection mechanism is used, problems may occur when the connection of some products is relatively firm, making it difficult to eject. Therefore, an injection mold base that facilitates demolding is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The injection mold frame of this utility model that facilitates demolding includes a support and a demolding device. A movable mold is slidably connected to the surface of the support, and a fixed mold is fixedly connected to the surface of the support. The demolding device is located on one side of the support and includes a support frame. The support frame is located on one side of the support, and two hydraulic rods are inserted into the inner surface of the support frame. A connecting block is fixedly connected to the side wall of the two hydraulic rods, and a scraper is fixedly connected to the side wall of the connecting block. The scraper is located on one side of the fixed mold. When the hydraulic rods are activated, they drive the connecting block and the scraper to move. When the scraper contacts the product, the product will be ejected from the surface of the fixed mold and fall off. By setting up the support frame, hydraulic rods, connecting blocks, and scraper, product demolding can be facilitated.

[0006] Preferably, two placement blocks are fixedly connected to the side wall of the support frame, and the hydraulic rod is inserted into the inner surface of the placement block. Two positioning pins are threadedly connected to the inner walls of the placement block and the hydraulic rod. After the hydraulic rod is inserted into the inner wall of the support frame, the positioning pins are rotated to the inner walls of the placement block and the hydraulic rod. The positioning pins and the placement block can restrict the position of the hydraulic rod.

[0007] Preferably, the bottom end of the support frame is rotatably connected to multiple support wheels, which roll on the ground. By setting the support wheels, the support frame can be easily moved.

[0008] Preferably, two reinforcing frames are fixedly connected to the surface of the support frame. When the support frame is under force, the support frame will transfer the force to the reinforcing frames, which can increase the strength of the support frame.

[0009] Preferably, the sidewalls of the bracket and the support frame are provided with limiting devices. The limiting device includes a threaded rod, the surface of which is rotatably connected to the surface of the bracket. A locking block is fixedly connected to the sidewall of the support frame, and a moving block is threadedly connected to the surface of the threaded rod. The locking block is inserted into the inner wall of the moving block. Pushing the support frame causes the support frame to move the locking block, and the locking block is inserted into the inner wall of the moving block. By setting the threaded rod, locking block, and moving block, the position of the support frame can be limited.

[0010] Preferably, the inner walls of the moving block and the locking block are threaded with a plug rod. After the locking block is inserted into the inner wall of the moving block, the plug rod is rotated to the inner wall of the moving block and the locking block. The plug rod can restrict the position of the locking block within the moving block.

[0011] Preferably, the surface of the movable block is provided with a storage groove, and the card block is inserted into the inner wall of the storage groove of the movable block. When the card block moves, the card block is inserted into the inner wall of the storage groove. The opening of the storage groove can facilitate the movable block to store the card block.

[0012] The advantages of this utility model are:

[0013] 1. When a moving mold and a fixed mold are required, the hydraulic rod is inserted into the inner wall of the support frame and the placement block. Then, the positioning pin is rotated to the inner wall of the placement block and the hydraulic rod, and the support frame is pushed to drive the support wheel to rotate. The support wheel rolls on the ground. After the support frame moves to the appropriate position, the support frame is stopped. After the product is produced, the two hydraulic rods are activated to drive the connecting block and the scraper to move. The scraper contacts the product and allows the product to be removed from the surface of the fixed mold. When the support frame is under force, the force is transmitted to the reinforcing frame. When it is necessary to demold the product on the moving mold, the direction of the scraper is adjusted. By setting the entire device, the product can be easily removed from the mold, reducing the situation where a single demolding structure cannot adapt to all products.

[0014] 2. Before using the support frame, rotate the threaded rod to make it rotate on the inner wall of the moving block. The threaded rod drives the moving block to move to a suitable position. After moving to the appropriate position, push the support frame to make the support frame drive the locking block to slide. The locking block is inserted into the inner wall of the storage slot of the moving block. Then rotate the insertion rod to the inner wall of the moving block and the locking block. By setting the entire device, the position of the support frame can be restricted, reducing the situation of the support frame moving randomly during use. At the same time, it is also convenient to adjust the fixed position of the support frame. Attached Figure Description

[0025] The bottom end of the support frame 41 is rotatably connected to multiple support wheels 47; during operation, the support frame 41 drives the support wheels 47 to rotate, and the support wheels 47 roll on the ground. By setting the support wheels 47, the support frame 41 can be moved to a convenient position.

[0026] Two reinforcing frames 48 are fixedly connected to the surface of the support frame 41. During operation, the support frame 41 transmits force to the reinforcing frames 48, which can increase the strength of the support frame 41.

[0027] The sidewalls of the bracket 1 and the support frame 41 are provided with limiting devices 5. The limiting device 5 includes a threaded rod 51, the surface of which is rotatably connected to the surface of the bracket 1. A locking block 52 is fixedly connected to the sidewall of the support frame 41. A moving block 53 is threadedly connected to the surface of the threaded rod 51.

Then, the positioning pin 46 is rotated to the inner wall of the placement block 45 and the hydraulic rod 42, and the support frame 41 is pushed to drive the support wheel 47 to rotate. The support wheel 47 rolls on the ground. After the support frame 41 moves to the appropriate position, it stops. After the product is produced, the two hydraulic rods 42 are activated to drive the connecting block 43 and the scraper 44 to move. The scraper 44 contacts the product, allowing the product to be removed from the surface of the fixed mold 3. When the support frame 41 is under force, the force is transmitted to the reinforcing frame 48. When it is necessary to demold the product on the moving mold 2, the scraper is adjusted. The orientation of plate 44, by setting the entire device, facilitates the removal of products from the mold, reducing the situation where a single demolding structure cannot accommodate all products; before using the support frame 41, rotate the threaded rod 51 to make the threaded rod 51 rotate on the inner wall of the moving block 53.
