Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold with a waste material recycling function. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. It is a method in which a completely molten plastic material is stirred by a screw at a certain temperature, injected into a mold cavity with high pressure, and a molded product is obtained after cooling and solidification. The advantages of the injection molding method are fast production speed, high efficiency, automated operation, a wide variety of colors, shapes from simple to complex, sizes from large to small, and precise product size. The product is easy to update and can be made into parts with complex shapes. Injection molding is suitable for mass production and molding processing fields such as products with complex shapes.

[0003] For example, the patent document with application number CN202021237364.9 discloses a toy mold with a centralized waste collection function. The utility model toy mold with a centralized waste collection function is easy to use, and can quickly clean and recycle toy waste in a centralized manner, thereby avoiding affecting the normal injection molding work of the toys and avoiding unnecessary losses. However, when the toy mold with a centralized waste collection function is in use, once the transmission mechanism responsible for pushing the scraper fails, the scraper will be unable to continue working subsequently, and since the interior of the mold is relatively small, the transmission mechanism cannot be disassembled, affecting the maintenance efficiency of the maintenance personnel.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 4 As shown, an injection mold with a waste recycling function includes a lower mold 1 and a limiting assembly 4. A slot 2 is opened on the right side of the lower mold 1, and a limiting block 3 is engaged inside the slot 2. The limiting assembly 4 for limiting and fixing the limiting block 3 is installed inside the limiting block 3. The limiting assembly 4 includes a lever 401, a transmission rod 402, a transmission gear 403, a gear rod 404 and a return spring 405. The bottom of the lever 401 is connected with the transmission rod 402, and the transmission gear 403 at the end of the transmission rod 402 is engaged with the outer wall of the transmission gear 403. The gear rod 404 is fixed with a return spring 405 at the end thereof, and the end of the return spring 405 is fixed to the limit block 3. The lever 401 is swung counterclockwise to cause the lever 401 to drive the transmission rod 402 at the end of which is provided with a transmission gear 403 to rotate, and the gear rod 404 meshed with its outer wall is pulled back into the limit block 3 through the transmission gear 403, so that the limit block 3 loses its restraining force, and moves upward and disengages together with the hydraulic push rod 5 and push plate 6 fixed inside the limit block 3, thereby achieving the purpose of disassembling the hydraulic push rod 5 and improving the efficiency of later maintenance.

[0024] Furthermore, hydraulic push rods 5 are inserted into the front and rear sides of the limit block 3 , and a push plate 6 is fixedly mounted on the left end of the hydraulic push rod 5 . The hydraulic push rod 5 is used to provide power for the movement of the push plate 6 .

[0025] Furthermore, a limiting rod 7 is slidably provided on the top of the lower mold 1, and an upper mold 8 is fixedly installed on the top of the limiting rod 7. The limiting rod 7 prevents the lower mold 1 and the upper mold 8 from being misaligned when they are closed.

[0026] Furthermore, an injection port 9 is connected through the top of the upper mold 8 , and a distal end of the injection port 9 extends into the lower mold 1 .

[0027] Furthermore, baffles 10 are vertically arranged on both sides of the bottom of the lower mold 1, and the length of the baffles 10 is consistent with the depth of the inner groove of the lower mold 1. The baffles 10 prevent the material from entering the lower trough 11 and affecting the processing of the finished product.

[0028] like Figure 5 As shown, a material discharge chute 11 is provided at the left bottom of the lower mold 1 , and a screw rod 12 is rotatably connected inside the material discharge chute 11 , and the screw rod 12 is used to transfer the waste material inside the material discharge chute 11 .

[0029] Furthermore, the front end of the spiral rod 12 is rotatably connected to a fixed plate 13, and a motor 14 is fixed to the front end of the fixed plate 13. The lower mold 1 is movably connected to a waste drawer 15 below the spiral rod 12, and the waste drawer 15 is used to collect the cleaned waste.

[0030] Working principle: When using the injection mold with waste recycling function, firstly, the lever 401 is swung counterclockwise to drive the transmission rod 402 with a transmission gear 403 at its end to rotate, and the transmission gear 403 pulls the gear rod 404 meshing on its outer wall to retract into the limit block 3, so that the limit block 3 loses its restraining force, and moves upward and disengages together with the hydraulic push rod 5 and the push plate 6 fixed inside the limit block 3, so as to achieve the purpose of disassembling the hydraulic push rod 5. After the maintenance is completed, the hydraulic push rod 5 pushes the push plate 6 to push the waste inside the lower mold 1 into the discharge chute 11, and then the motor 14 drives the spiral rod 12 set inside the discharge chute 11 to rotate through the output shaft, and the waste cleaned by the push plate 6 is rolled into the discharge chute 11, and then enters the waste drawer 15 through the discharge port opened at the bottom of the front end of the discharge chute 11, so as to achieve the purpose of centralized transfer of waste. This is the working principle of the injection mold with waste recycling function.
