[0002] In the production of plastic products, the shaping process plays a crucial role. It determines the final shape, size, and surface quality of the product, which in turn affects its performance and aesthetics. Therefore, the development of efficient and precise shaping devices is crucial for improving the production efficiency and quality of plastic products.

[0003] After searching, the utility model with Chinese patent publication number CN216139282U discloses a shaping device for processing plastic products, including a lower shaping plate and an upper shaping plate. The bottom of the lower shaping plate is provided with an operating table, the top of the operating table is provided with a rectangular groove, and a servo motor is installed on the inner wall of the rectangular groove. The bottom of the lower shaping plate is fixedly connected to a limit plate, and the surface of the limit plate is rotatably connected to a support rod, and one end of the support rod is rotatably connected to a U-shaped block.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a technical solution: Figure 2 、 Figure 3 and Figure 4As shown, in this embodiment, a shaping device for processing plastic products includes a base plate 1, a support frame 2 is fixedly connected to the top outer wall of the base plate 1, an opening and closing component 5 is installed inside the support frame 2, the opening and closing component 5 includes four mounting shafts 501 rotatably connected to the inside of the support frame 2, and the four mounting shafts 501 are arranged opposite to each other, and the same lower mold 3 is rotatably connected to two relative mounting shafts 501, and the two lower molds 3 can form a complete chamber, and the bottom outer walls of the two lower molds 3 are rotatably connected to a push-pull plate 504, and a discharge component 6 is installed on the top of the base plate 1, and the discharge component 6 is located on one side of the support frame 2.

[0025] A hydraulic cylinder 502 is fixedly installed in the middle of the top outer wall of the bottom plate 1, and a movable sleeve 503 is coaxially fixed to the output end of the hydraulic cylinder 502. One end of the bottom of the two push-pull plates 504 is rotatably connected to the inside of the movable sleeve 503.

[0026] Start the hydraulic cylinder 502 on the top of the base plate 1, and the output end of the hydraulic cylinder 502 drives the movable sleeve 503 to move downward, and the push-pull plate 504 installed inside the movable sleeve 503 will also be driven to move synchronously, and one corner of the lower mold 3 is fixed by the installation shaft 501, so the movable sleeve 503 can drive one end of the lower mold 3 to flip downward through the push-pull plate 504, and then the plastic product will move out of the cavity, and a part of it will be in a suspended state, which is more convenient to operate.

[0027] like Figure 1 and Figure 2 As shown, the interiors of the two lower molds 3 are both hollow, and two connecting pipes 4 are provided on the outer walls of the two lower molds 3 on the sides away from each other, and the two connecting pipes 4 are both connected to the internal space of the lower molds 3.

[0028] The coolant enters the lower mold 3 through a connecting pipe 4 and is then discharged to the outside from another connecting pipe 4, thereby circulating, and the plastic products in the cavity formed by the two lower molds 3 will also be cooled and shaped.

[0029] like Figure 1 and Figure 2 As shown, the discharge assembly 6 includes a mounting bracket 601 fixedly connected to one side of the top outer wall of the base plate 1, a connecting bracket 603 fixedly connected to one side of the outer wall of the mounting bracket 601, an air outlet pipe 604 fixedly connected to the top of the connecting bracket 603, the air outlet pipe 604 is located on one side of the lower mold 3, and the air outlet pipe 604 is connected to the external air supply equipment through a pipeline.

[0030] A control button 602 is installed on the top outer wall of the mounting frame 601 . The control button 602 is electrically connected to the valve inside the pipeline through a wire, and a corner at the bottom of the lower mold 3 can contact the control button 602 .

[0031] When the lower mold 3 flips to a certain extent, one of its corners will squeeze the control button 602, and the control button 602 controls the valve of the air inlet pipe to open, and the air flow enters the air outlet pipe 604, and then shoots toward the plastic product from the nozzle. If the plastic product is in the lower mold 3 on the left, the air flow will apply external force from the back of the plastic product. If the plastic product is in the lower mold 3 on the right, the air flow will apply external force from the inner cavity of the plastic product, thereby realizing discharge.

[0033] like Figure 2 As shown, the corners of the two lower molds 3 that are close to each other are both rounded, and the center of the rounded corner coincides with the center axis of the installation shaft 501, ensuring that the lower molds 3 can be turned normally when flipped and that the two lower molds 3 fit tightly enough.

[0034] The utility model provides a shaping device for processing plastic products, and the specific working principle is as follows:

[0035] When the device is working, the coolant enters the lower mold 3 through a connecting pipe 4, and is then discharged to the outside from another connecting pipe 4, thereby circulating. The plastic products in the cavity formed by the two lower molds 3 will also be cooled and shaped. The hydraulic cylinder 502 on the top of the bottom plate 1 is started, and the output end of the hydraulic cylinder 502 drives the movable sleeve 503 to move downward. The push-pull plate 504 installed inside the movable sleeve 503 will also be driven to move synchronously, and one corner of the lower mold 3 is fixed by the installation shaft 501. Therefore, the movable sleeve 503 can drive one end of the lower mold 3 to flip downward through the push-pull plate 504, and then the plastic product will move out of the cavity. The lower mold 3 is turned over to a certain extent, and one of its corners will squeeze the control button 602. The control button 602 controls the valve of the air inlet pipe to open, and the airflow enters the air outlet pipe 604, and then is ejected from the nozzle toward the plastic product. If the plastic product is in the lower mold 3 on the left, the airflow will apply external force from the back of the plastic product. If the plastic product is in the lower mold 3 on the right, the airflow will apply external force from the inner cavity of the plastic product, thereby realizing discharge.
