[0003] Existing technologies often have the following drawbacks: after processing the product, manual assembly is often required. Manual assembly results in low product assembly efficiency and requires considerable effort to join the products together, which cannot meet the product assembly requirements.

[0004] Therefore, this utility model provides a common mold in-mold assembly mechanism for different products. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of low product assembly efficiency in existing technologies by proposing a common mold in-mold assembly mechanism for different products.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a common mold in-mold assembly mechanism for different products, including a first mold and a second mold, wherein a partition strip is slidably connected inside the first mold, and an assembly device is provided on the inner side of the first mold, the assembly device including two push plates slidably connected to the inner side of the first mold.

[0007] The effect achieved by the above components is as follows: by setting up an assembly device, after the product is injection molded, the partition bar is driven to retract into the interior of the first mold, and then the two push plates are pushed towards each other by extrusion, thereby realizing the assembly of products in the film and improving the efficiency of in-film assembly of products.

[0008] Preferably, the first mold has two sliding frames inside, and the sliding frames and the push plate are internally slidably connected.

[0009] The effect achieved by the above components is to adjust the lateral distance between the two sliding frames so that the sliding frames are initially close to the sides of the product to be spliced, in preparation for the pressing action of the push plate.

[0010] Preferably, a drive plate is fixedly connected to the lower side of the slide frame, and a lead screw is threadedly connected to the inside of the drive plate. The lead screw is rotatably connected to the inside of the first mold.

[0011] The effect achieved by the above components is that, since the lead screw is threadedly connected to the drive plate and the drive plate is fixedly connected to the slide frame, the rotation of the lead screw is converted into the lateral movement of the drive plate.

[0012] Preferably, four connecting rods are fixedly connected to the surface of the first mold in pairs, and an installation ring is fixedly connected between two of the connecting rods. A motor is fixedly installed on the inner side of the installation ring, and the output end of the motor is fixedly connected to the lead screw.

[0013] The effect achieved by the above components is that the motor output drives the lead screw to rotate.

[0014] Preferably, the sliding frame is internally threaded with a drive rod, and the drive rod is internally rotatably connected to the push plate.

[0015] The effect achieved by the above components is as follows: by rotating the drive rod inside the slide frame, since the drive rod is rotatably connected to the push plate and the push plate is slidably connected to the slide frame, the rotation of the drive rod will push the push plate to move towards the product along the longitudinal sliding trajectory of the slide frame.

[0016] Preferably, the surface of the first mold is provided with a shielding structure, the shielding structure including a fixed plate fixedly connected to the side wall of the first mold, a movable frame slidably connected inside the fixed plate, and a baffle fixedly connected to the end side of the movable frame.

[0018] Preferably, the movable frame is a rectangular ring structure.

[0019] The effect achieved by the above components is that the rectangular frame structure prevents the movable frame from slipping out of the fixed plate.

[0020] Preferably, the fixed plate has a sliding pin inside, and the side wall of the movable frame has a plurality of slots, the size of which is adapted to the size of the slots.

[0021] The effect achieved by the above components is to push the pin to slide along the inside of the fixed plate and insert it into the corresponding slot on the side wall of the moving frame.

[0030] Reference Figure 1 As shown, this utility model provides a technical solution: a common mold in-mold assembly mechanism for different products, including a first mold 1 and a second mold 2. A partition strip 3 is slidably connected inside the first mold 1, an assembly device 4 is provided on the inner side of the first mold 1, and a shielding structure 5 is provided on the surface of the first mold 1.

[0031] The specific setup and function of its assembly device 4 and shielding structure 5 will be explained below.

[0032] Reference Figures 1-3 As shown, in this embodiment, the assembly device 4 includes two push plates 41 slidably connected to the inner side of the first mold 1. By setting the assembly device 4, after the product is injection molded, the drive separator 3 retracts into the interior of the first mold 1, and then the two push plates 41 are pushed towards each other by extrusion, thereby realizing the in-film assembly of products and improving the efficiency of in-film assembly. Two sliding frames 43 are slidably connected inside the first mold 1, and the sliding frames 43 are slidably connected to the push plates 41. The lateral distance between the two sliding frames 43 is adjusted so that the sliding frames 43 initially approach the two sides of the products to be assembled, preparing for the extrusion action of the push plates 41. A drive plate 48 is fixedly connected to the lower side of the sliding frame 43, and a lead screw 47 is threadedly connected inside the drive plate 48. The lead screw 47 is rotatably connected to the interior of the first mold 1. Since the lead screw 47 is threadedly connected to the drive plate 48, and the drive plate 48 is fixedly connected to the sliding frame 43, the rotation of the lead screw 47 is converted into the lateral movement of the drive plate 48. Four connecting rods 45, arranged in pairs, are fixedly connected to the surface of the first mold 1. A mounting ring 46 is fixedly connected between two connecting rods 45. A motor 42 is fixedly mounted inside the mounting ring 46, and the output end of the motor 42 is fixedly connected to a lead screw 47. The output end of the motor 42 drives the lead screw 47 to rotate. A drive rod 44 is threadedly connected inside the slide frame 43, and the drive rod 44 is rotatably connected to the push plate 41. By rotating the drive rod 44 inside the slide frame 43, because the drive rod 44 is rotatably connected to the push plate 41, and the push plate 41 is slidably connected to the slide frame 43, the rotation of the drive rod 44 will push the push plate 41 to move along the longitudinal sliding trajectory of the slide frame 43 towards the product.

[0033] Reference Figures 1-2 and Figure 4As shown, specifically, the shielding structure 5 includes a fixed plate 51 fixedly connected to the side wall of the first mold 1. A movable frame 52 is slidably connected inside the fixed plate 51, and a baffle 53 is fixedly connected to the end of the movable frame 52. By setting the shielding structure 5, after the first mold 1 and the second mold 2 are opened, during the assembly of the in-mold products, the movable baffle 53 moves above the two products, which can realize the limiting shielding work when the products are spliced, further improving the splicing efficiency of the products. The movable frame 52 is a rectangular ring structure. The rectangular frame structure of the movable frame 52 prevents it from slipping out of the fixed plate 51. A pin 56 is slidably connected inside the fixed plate 51, and several slots 54 are opened on the side wall of the movable frame 52. The size of the pin 56 is adapted to the size of the slot 54. Pushing the pin 56 to slide along the inside of the fixed plate 51, it is inserted into the corresponding slot 54 on the side wall of the movable frame 52. A pull block 55 is fixedly connected to the end of the pin 56. The pull block 55 facilitates the pulling of the pin 56. A spring 57 is fitted onto the surface of the pin 56, and the two ends of the spring 57 are fixedly connected to the pull block 55 and the fixing plate 51, respectively. When the spring 57 on the surface of the pin 56 returns to its elastic deformation, it pushes the pin 56 to slide along the inside of the fixing plate 51.

[0034] Working principle: Before operation, the first mold 1 and the second mold 2 are precisely closed to form a complete injection cavity. At this time, the partition strip 3 inside the first mold 1 is in the extended state, dividing the cavity into two independent areas, corresponding to two different shapes of products to be processed. This ensures that the two products can be formed in their respective areas during injection molding, avoiding material mixing. Material injection and product forming: The injection molding machine injects molten material into the two separated cavity areas. After the material cools and solidifies in the cavity, it forms two semi-finished products that can be joined together. After the product is injection molded, the partition strip 3 inside the first mold 1 is driven to retract into the mold along the sliding direction, connecting the two previously separated cavity areas and making room for subsequent product joining. The position of the sliding frame 43 is adjusted, and the motor 42, which is fixed in the mounting ring 46 on the surface of the first mold 1, is started. 2. The output end drives the lead screw 47 to rotate. Since the lead screw 47 is threadedly connected to the drive plate 48 and the drive plate 48 is fixedly connected to the slide frame 43, the rotation of the lead screw 47 will be converted into the lateral movement of the drive plate 48, which in turn drives the slide frame 43 to move synchronously along the sliding trajectory inside the first mold 1. By controlling the direction and speed of the two motors 42, the lateral distance between the two slide frames 43 can be adjusted, so that the slide frames 43 initially approach the two sides of the product to be spliced, preparing for the pressing action of the push plate 41. By rotating the drive rod 44 inside the slide frame 43, since the drive rod 44 is rotatably connected to the push plate 41 and the push plate 41 is slidably connected to the slide frame 43, the rotation of the drive rod 44 will push the push plate 41 along the longitudinal sliding trajectory of the slide frame 43 towards the product. The two push plates 41 apply uniform extrusion force from the outside of the two products, making the two products fit precisely along the splicing surface. This allows for adjustment of the splicing force. The entire process is mechanically driven, replacing manual operation, which not only improves assembly efficiency but also ensures the stability and consistency of the splicing force, avoiding product splicing deviations caused by uneven force during manual assembly. The baffle 53 moves and limits the movement. While the assembly device 4 drives the push plates 41 to splice the products, it can also move the movable frame 52 within the fixed plate 51 on the side wall of the first mold 1. The movable frame 52 is a rectangular ring structure that adapts to the sliding trajectory of the fixed plate 51, ensuring movement stability. This moves the baffle 53, which is fixedly connected to the end of the movable frame 52, to... Above the two products to be spliced, the baffle 53 acts as a limiter during the splicing process, preventing the products from shifting upwards when pressed by the pusher plate 41. It also prevents external impurities from falling into the splicing surface and affecting the splicing quality. Once the baffle 53 moves to the appropriate blocking position, the tension on the end pull block 55 of the pin 56 is released. At this time, the spring 57 on the surface of the pin 56 returns to its elastic deformation, pushing the pin 56 to slide along the inside of the fixed plate 51 and insert into the corresponding slot 54 on the side wall of the moving frame 52. Because the size of the pin 56 matches the size of the slot 54, the positions of the moving frame 52 and the baffle 53 can be fixed, ensuring that the baffle 53 remains in the limiting position throughout the splicing process, continuously providing a stable blocking and limiting effect for the product splicing.If the position of baffle 53 needs to be adjusted later, simply pull the pull block 55 to cause the pin 56 to overcome the spring force of spring 57 and be pulled out of slot 54. Then the moving frame 52 can be moved again. After the finished product is removed, the separator 3 is extended again, closing the first mold 1 and the second mold 2, and entering the next injection molding assembly cycle, thus achieving continuous production.
