Only the blade can be used to shear the long strip of injection molding. It is more convenient to shear, which can meet the needs of shearing long strips of injection molding.

[0003] The problem with the prior art is that when the shearing device for injection molded parts is used, the blade needs to be lifted up manually by a handle, and then the handle is pressed down to shear the injection molded parts. However, this manual shearing method not only easily leads to uneven shearing edges, reducing product quality and shearing efficiency, but also causes hand fatigue due to long-term manual operation, which ultimately leads to an inability to work normally. Summary of the invention

[0023] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0024] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 6 As shown, the injection molding part glue mouth shearing machine provided by the embodiment of the utility model includes a base 4, a placing table 13 for placing products is fixedly installed on the upper surface of the base 4, a lifting mechanism 20 is arranged on the base 4, a slide 6 is fixedly installed on the lifting mechanism 20, the slide 6 is located directly above the placing table 13, blades 8 are fixedly installed on both sides of the lower surface of the slide 6, fixed seats 10 are fixedly installed on the base 4 located on both sides of the placing table 13, cylinders 11 are fixedly installed on the opposite sides of the two fixed seats 10, two telescopic rods 14 are fixedly installed on the upper surface of the placing table 13, each telescopic rod 14 is provided with a spring 16, and each telescopic rod 14 is fixedly connected to a top block 15 at the output end.

[0026] In the present application, after the formed product is sheared under the shearing machine, its material handle 3 is ejected with the cooperation of the telescopic rod 14, the spring 16 and the ejector block 15, thereby improving the efficiency of removing waste materials, avoiding the trouble of manually reaching into the shearing machine to remove materials, and also improving the safety of manual material removal.

[0027] Furthermore, a slide groove 401 is opened on the front side of the base 4, and the lifting mechanism 20 includes a motor 19, which is fixedly installed on the upper end of the base 4. A ball screw 5 is rotatably installed in the slide groove 401, and the output shaft of the motor 19 is fixedly connected to the upper end of the ball screw 5. A movable plate 7 is arranged on the ball screw 5, and the movable plate 7 is fixedly sleeved on the outer surface of the ball on the ball screw 5. The movable plate 7 slides along the inner wall of the slide groove 401, and the slide 6 is fixedly installed on the front side of the movable plate 7.

[0028] In the present application, the ball screw 5 is driven to rotate by the motor 19, thereby driving the balls thereon to move. The movement of the balls will synchronously drive the movable plate 7 to move, thereby achieving the purpose of moving the slide 6 up and down. The setting of the slide groove 401 improves the stability of the slide 6 during movement, avoids displacement deviation of the slide 6 during movement, and thus affects the shearing quality.

[0029] Furthermore, a rubber pressing block 9 is fixedly connected to the output end of each cylinder 11 , and bearing blocks 17 are fixedly installed on both sides of the upper surface of the placement table 13 , and the bearing blocks 17 correspond to the rubber pressing blocks 9 .

[0030] In the present application, the provision of the rubber pressing block 9 can prevent damage to the product when the product is fixed, thereby improving the quality and integrity of the product after shearing.

[0031] Furthermore, the two telescopic rods 14 are located between the two bearing blocks 17 , and the two ends of the spring 16 are fixedly connected to the lower surface of the top block 15 and the upper surface of the placement platform 13 respectively.

[0032] In the present application, the elastic force of the two springs 16 is greater than the gravity of the molded product before shearing. When shearing the molded product, the molded product is first placed on the two supporting blocks 17. At this time, under the elastic force of the spring 16, the two top blocks 15 drive the molded product to move upward. At this time, the molded product is separated from the supporting block 17, and then driven by the two cylinders 11, the two rubber pressure blocks 9 are driven to move downward to fix the product. At this time, the spring 16 is compressed, and finally the two blades 8 move downward under the drive of the motor 19 to complete the shearing of the material handle 3. At this time, the two springs 16 are reset, thereby driving the two top blocks 15 to move upward, and finally the sheared material handle 3 is ejected so that it can be removed manually.

[0033] Furthermore, the formed left product 1 and right product 2 are placed on the supporting block 17 , and a material handle 3 is fixedly connected between the left product 1 and the right product 2 , and the material handle 3 is located between the two supporting blocks 17 .

[0034] Furthermore, each blade 8 is respectively disposed on the inner side of each bearing block 17 .

[0035] In the present application, two blades 8 are arranged on the inner side of each bearing block 17 , so that the bearing block 17 can limit the blades 8 and improve the stability of the blades 8 .

[0036] The working principle of this utility model:

[0037] When in use, first place the formed product on the bearing block 17, so that the left product 1 and the right product 2 are respectively opposite to the top of each bearing block 17. Since the spring 16 is in a natural state at this time, the two top blocks 15 push the material handle 3 upward, and the left product 1 and the right product 2 are separated from the bearing block 17. Then, the two cylinders 11 are started to drive the two rubber pressing blocks 9 to move downward to fix the products. At this time, the two springs 16 are compressed, and then the motor 19 is started to drive the ball screw 5 to rotate, thereby driving the ball on it to move. The movement of the ball will synchronously drive the moving plate 7 to move, and the movement of the moving plate 7 will drive the blade 8 fixedly connected to the slide 6 to move downward, finally achieving the purpose of shearing the material handle 3.

[0038] Then the motor 19 is started again to drive the slide 6 to move upward, at which time the spring 16 is reset, so that the two ejector blocks 15 eject the sheared material handle 3 so that it can be taken out manually.

[0039] In summary, the injection molding glue mouth shearing machine, through the coordinated cooperation of the telescopic rod 14, the spring 16 and the ejector block 15, is convenient for ejecting the sheared material handle 3 from the shear, which not only improves the efficiency of removing waste materials; but also avoids the trouble of manually reaching into the shearing machine to take materials, and also improves the safety of manual material taking; through the arrangement of the lifting mechanism 20, the slide 6 and the two blades 8, the material handle 3 is automatically sheared, which effectively solves the problems that most of the existing injection molding parts rely on manual shearing, resulting in uneven shearing edges, reduced product quality after shearing, and hand fatigue caused by long-term manual operation.
