[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. In this utility model, by setting an auxiliary material picking mechanism, when the upper mold moves upward, the baffle in the built-in groove of the upper mold drives the locking block to move upward, the locking block drives the connecting block to move upward, and the connecting block drives the connecting box to move upward through the moving block and the support rod. The connecting box drives the connecting plate on one side to move upward, so that the two connecting plates drive the picking rack to move upward at the same time, so that the picking rack ejects the finished product, avoiding the finished product from sticking to the injection molded tank and causing difficulties in picking up the material.

[0020] 2. In this utility model, by setting up a disturbance device, coolant is transported to the cooling tank through an external pipe and impacts the disturbance plate, causing the disturbance plate to rotate. Then, the disturbance plate drives the connecting rod to rotate, causing the two ends of the connecting rod to stretch the springs respectively. The springs generate a rebound force, which drives the disturbance plate to rotate in the opposite direction through the connecting rod, thereby disturbing the coolant entering the cooling tank. This allows the coolant at the bottom to mix with the coolant at the top, preventing the coolant at the top from absorbing too much heat and reducing the cooling effect. This prevents the finished product from being deformed when it is unloaded due to insufficient cooling. Attached Figure Description

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 This utility model provides a technical solution: an injection mold with an auxiliary demolding structure, including an upper mold 1 and a lower mold 2. The lower mold 2 has an injection groove 7 on its top and an auxiliary material handling mechanism 4 on its top. The auxiliary material handling mechanism 4 includes two movable grooves 416, two built-in grooves 413, and an embedded groove 414. A connecting box 412 is slidably connected in the movable grooves 416, and a moving block 409 is slidably connected in the connecting box 412. A connecting block 402 is connected to the top of the moving block 409, and a locking block 401 is connected to the top of the connecting block 402. A sliding sleeve is embedded in the moving block 409, and a support rod 410 is slidably connected in the sliding sleeve. A return spring 411 is sleeved on the outer wall of the support rod 410. Rotating blocks 405 are rotatably connected to both sides of the inner wall of the built-in grooves 413, and a baffle 404 is connected between the two rotating blocks 405. A limit plate 408 is attached to one side of the top of the baffle 404. A connecting plate 406 is connected to one side of the connecting box 412, and the two connecting blocks 405 are connected to the same baffle 404. A common material picker 407 connects the plates 406. A connecting groove 415 is provided on one side of the movable groove 416. The movable groove 416 is located at the top of the lower mold 2. The built-in groove 413 is located at the bottom of the upper mold 1. The embedded groove 414 is located at the bottom of the injection mold 7, and one side of the connecting groove 415 is connected to one side of the embedded groove 414. The two sides of the limiting plate 408 are respectively connected to the two sides of the inner wall of the built-in groove 413. The material picker 407 fits against the embedded groove 414. The two ends of the support rod 410 are respectively The two sides of the inner wall of the connecting box 412 are connected, and the two ends of the return spring 411 are respectively connected to one side of the moving block 409 and one side of the inner wall of the connecting box 412. The top side of the movable groove 416 is provided with an inclined surface. The two sides of the inner wall of the movable groove 416 are provided with limit grooves 417, and the limit block 403 is slidably connected in the limit groove 417. One side of the limit block 403 is connected to one side of the connecting box 412. The top of the lower mold 2 is provided with two allowance grooves 8, and the position of the allowance grooves 8 corresponds to that of the baffle 404.

[0029] In a specific implementation, an auxiliary material handling mechanism 4 is provided. The upper mold 1 is driven downwards by the driving mold, causing the upper mold 1 to move the baffle 404 within the built-in groove 413 downwards. When the bottom of the baffle 404 contacts the top of the locking block 401, the baffle 404 rotates around the rotating block 405 as the upper mold 1 continues to move downwards. When one side of the baffle 404 is misaligned with one side of the locking block 401, the baffle 404 is reset by weight. After injection molding is completed, the driving mold... When the upper mold moves upward, the baffle 404 in the inner groove 413 of the upper mold 1 causes the locking block 401 to move upward. The locking block 401 causes the connecting block 402 to move upward, which in turn causes the connecting block to move the connecting box 412 upward through the moving block 409 and the support rod 410. The connecting box 412 causes the connecting plate 406 on one side to move upward, which causes both connecting plates 406 to simultaneously move the material picker 407 upward, so that the material picker 407 ejects the finished product, preventing the finished product from sticking to the injection molded groove 7 and causing difficulties in material picking. When the limit block After block 403 moves to the top of the limiting groove 417, it is pressed by the inclined surface of one side of the locking block 401, causing the locking block 401 to move to one side. This causes the locking block 401 to move the connecting block 402, which in turn moves the moving block 409. The moving block 409 then presses against the return spring 411, causing the return spring 411 to generate a restoring force. When the baffle 404 is misaligned with the locking block 401, the connecting block 402, through the restoring force of the return spring 411, causes the moving block 409 to reset, thus... The moving block 409 causes the connecting block 402 to reset, and the gravity of the connecting block 402 causes the connecting box 412 and the material picker 407 to move down and reset. The limiting plate 408 blocks and limits one side of the baffle 404, and prevents the baffle 404 from rotating in the opposite direction when it is under force, thus affecting the lifting force. The allowance groove 8 prevents the side of the baffle 404 away from the blocking block 401 from contacting the top of the lower mold 2 when it rotates downward, thus affecting the rotation of the baffle 404 and the operation.

[0030] Cooling grooves 6 are provided in both the upper mold 1 and the lower mold 2. Two external pipes 3 are connected to one side of the inner wall of the cooling groove 6, and a liquid outlet pipe is connected to the other side of the cooling groove 6. Multiple disturbance devices 5 are provided in the inner wall of the cooling groove 6. The disturbance device 5 includes multiple placement grooves 501 and multiple disturbance plates 505. Springs 503 are installed in the placement grooves 501, and the same connecting rod 502 is connected between two corresponding springs 503. Through grooves 504 are provided in the disturbance plates 505. The inner wall of the through grooves 504 is connected to the outer wall of the connecting rod 502, and multiple internal grooves 413 are respectively opened on both sides of the inner wall of the cooling groove 6.

[0031] In a specific implementation, a disturbance device 5 is installed, and coolant is delivered to the cooling tank 6 through the external pipe 3. The coolant impacts the disturbance plate 505, causing the disturbance plate 505 to rotate under force. The rotation of the disturbance plate 505 drives the connecting rod 502 to rotate, causing the two ends of the connecting rod 502 to stretch the spring springs 503 respectively. The spring springs 503 generate a rebound force, and then the rebound force of the spring springs 503 drives the connecting rod 502 to reset and rotate. Thus, the connecting rod 502 drives the disturbance plate 505 to rotate in the opposite direction, causing the disturbance plate 505 to disturb the coolant entering the cooling tank 6. This allows the coolant at the bottom to mix with the coolant at the top, preventing the upper coolant from absorbing too much heat and reducing the cooling effect. This prevents the finished product from being deformed during material handling due to insufficient cooling.

[0032] Working principle: During use, the drive module moves the upper mold 1 downward, causing it to fit against the lower mold 2. During this fitting process, the bottom of the baffle 404 contacts the top of the locking block 401, causing the baffle 404 to rotate around the rotating block 405. As the upper mold 1 continues to move downward, the baffle 404 and the locking block 401 become misaligned on one side. The eccentric rotating block 405 then resets the baffle 404. Coolant is then introduced through the external pipe 3, causing it to impact the disturbance plate 505. The disturbance plate 505 rotates, agitating the coolant and causing it to flow between the upper and lower layers. The mixture is mixed to prevent the upper coolant from absorbing too much heat, which would reduce the cooling effect and prevent the finished product from being deformed due to insufficient cooling. Then, the upper mold 1 is moved upward by the drive module, which in turn moves the baffle 404. The baffle 404 moves the locking block 401 upward, the locking block 401 moves the connecting block 402 upward, and the connecting block 402 moves the moving block 409 upward. The moving block 409 moves the connecting box 412 upward through the support rod 410. The connecting box 412 moves the picking rack 407 upward through the connecting plate 406, so that the picking rack 407 ejects the finished product, avoiding the problem of the finished product sticking to the lower mold 2, which would make it difficult to pick up the product.
