Technical Field
[0001] This utility model relates to the field of plastic product preparation, specifically to a discharge device for plastic product preparation. Background Technology
[0002] In the production of plastic products, thermoforming is a crucial step. However, traditional thermoforming often involves directly immersing the product in water for cooling and shaping. However, the temperature of the plastic products discharged from the extruder is too high, and directly introducing them into the water will create a height difference that causes the plastic products to bend downwards into the water, which can easily lead to deformation and affect the quality of the plastic products. Therefore, there is an urgent need for a discharge device for plastic product manufacturing to solve the above problems. Utility Model Content

Detailed Implementation
[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-5 This utility model provides an embodiment of a discharge device for manufacturing plastic products, comprising a cooling and shaping mechanism 1 and a support and adjustment mechanism 2. The cooling and shaping mechanism 1 is located at the top of the support and adjustment mechanism 2. The cooling and shaping mechanism 1 includes a flowing water tank 3 and a shaping mold 5. The shaping mold 5 can be designed with various specifications to adapt to different plastic products. Fixed plates 4 are fixedly connected to the bottom of both ends of the flowing water tank 3. Mold fixing plates 10 are fixedly installed at both ends of the flowing water tank 3. An insertion interface 11 is provided through the middle of the mold fixing plate 10. Overflow arc plates 7 are fixedly connected to both sides of the top of the flowing water tank 3. The design of the overflow arc plates 7 allows water overflowing from both sides of the flowing water tank 3 to flow to the outside of the flowing water tank 3, avoiding... Contact with the flowing water tank 3 will transfer heat to the flowing water tank 3, affecting the cooling effect. The bottom end of the flowing water tank 3 is fixedly connected to the water inlet pipe 6. The shaping mold 5 is movably inserted into the inner side of the insertion interface 11. The two ends of the shaping mold 5 are respectively fixedly connected to the positioning baffles 8. The mold inner groove 9 is opened through the inside of the shaping mold 5. The shaping mold 5 is set inside the flowing water tank 3. The positioning baffles 8 are close to the mold fixing plate 10 on the side near the flowing water tank 3. The two positioning baffles 8 can lock the shaping mold 5 between the two mold fixing plates 10 to prevent the shaping mold 5 from moving when the water plastic product is discharged. The top of both sides of the flowing water tank 3 is lower than the top of the mold fixing plate 10, so that the water overflowing from the flowing water tank 3 is discharged from both sides of the flowing water tank 3.
[0022] The cooling and shaping mechanism 1 includes a base support 12 and a water tank 13. Two base supports 12 are symmetrically arranged, and two limiting slide rods 14 are symmetrically fixed between the two base supports 12. A threaded rod 15 is rotatably installed between the two base supports 12. By rotating the threaded rod 15, the water tank 13 can be pushed to slide on the limiting slide rods 14, thereby adjusting the position of the water tank 13 and the shaping mold 5. A support frame 17 is fixedly connected to the top center of the water tank 13. A water pump 16 is fixedly installed in the middle of the bottom of the water tank 13. The water pump 16 delivers clean water inside the water tank 13 to the interior of the flowing water tank 3 to form a water flow and improve the cooling effect. The bottom sides of the water tank 13 are slidably connected to the two limiting slide rods 14. The bottom center of the water tank 13 is threadedly connected to the outside of the threaded rod 15. The threaded rod 15 is located in the middle position of the two limiting slide rods 14.
[0023] The cooling and shaping mechanism 1 is located at the top center of the support frame 17, and the cooling and shaping mechanism 1 is fixedly installed at the top of the support frame 17 by the fixing plate 4. Setting the cooling and shaping mechanism 1 at the top of the water tank 13 allows the water overflowing from the flowing water tank 3 to flow back into the interior of the water tank 13 to form a water circulation. The top of the water inlet pipe 6 is provided with two branch ends. The water inlet pipe 6 is connected to the bottom of the flowing water tank 3 through the two branch ends. Clean water is input through the two branch ends to increase the uniformity of the water flow. The bottom of the water inlet pipe 6 is connected to the output end of the water pump 16 through a hose.
[0024] Working principle: During use, firstly, select the corresponding molding die 5 according to the shape of the plastic product to be manufactured, and inject clean water into the water tank 13. Then, place the molding die 5 inside the flowing water tank 3 and insert both ends of the molding die 5 into the two insertion interfaces 11 respectively. Fix the mold fixing plate 10 to both ends of the flowing water tank 3 with bolts. At this time, the molding die 5 is pressed against the inner side of the two mold fixing plates 10 by the positioning baffles 8 at both ends, and the molding die 5 is suspended inside the flowing water tank 3. Then, the plastic product extruded by the extruder passes through the inner groove of the mold 9 and exits from the other end of the inner groove of the mold 9. Then, start the water pump 16. The water pump 16 delivers the clean water inside the water tank 13 to the water inlet pipe 6 through the hose. The clean water is delivered to the inside of the flowing water tank 3 through the two branch ends at the top of the water inlet pipe 6. When the water inside the flowing water tank 3 is full, it flows out through both sides of the flowing water tank 3. The water flows out through the top of the overflow arc plate 7. The water tank 13 is moved to the outside of the flow tank 3, and then the threaded rod 15 is rotated by external force. Since the bottom end of the water tank 13 is threadedly connected to the outside of the threaded rod 15, the rotating threaded rod 15 can push the water tank 13 to move closer to the outlet position of the extruder. The movement of the water tank 13 drives the cooling and shaping mechanism 1 to move to the shaping mold 5 near the outlet end of the extruder, reducing the distance between the two and reducing the deformation range of the thermoformed plastic product. The heat of the plastic product inside the shaping mold 5 is transferred to the clean water inside the flow tank 3 through the shaping mold 5. The clean water absorbs the heat and flows to the top of the flow tank 3 to be discharged, thereby cooling the shaping mold 5. After the temperature of the shaping mold 5 drops, it will cool and shape the plastic product inside. The plastic product output from the end of the mold groove 9 away from the extruder achieves the shaping effect. Moreover, the clean water discharged through the flow tank 3 falls back into the water tank 13 and is cooled during the falling process, thereby achieving the effect of circulating heat dissipation.
