Technical Field

[0001] This utility model belongs to the field of plastic product manufacturing technology, and in particular relates to a cooling molding device for manufacturing plastic products. Background Technology

[0002] Cooling and molding equipment for plastic product manufacturing is an important part of plastic processing production lines, mainly used to rapidly cool and solidify plastic products. In processes such as plastic injection molding, blow molding, and extrusion molding, the molten plastic needs to be cooled rapidly after molding to ensure the dimensional accuracy and appearance quality of the finished products.

[0003] The existing patent CN218342636U discloses a cooling molding apparatus for manufacturing plastic products. This cooling molding apparatus aims to solve the technical problem that existing cooling molding apparatuses for plastic products generally use spraying to cool the plastic products. After the coolant is sprayed onto the surface of the plastic product, the plastic product is cooled quickly. However, as the temperature of the plastic product decreases, the cooling effect of the coolant is not good, which reduces the cooling effect of the plastic product.

[0005] The disadvantages of existing patents: Existing technologies use spray heads to spray plastic products, and the water after spraying cannot be treated and can only be discharged through drainage tanks, which is a great waste of water resources. Summary of the Invention

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] 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.

[0022] Please see Figs. 1-3 This utility model provides a technical solution: a cooling molding device for manufacturing plastic products, including a bracket 1, a support frame 2 slidably connected inside the bracket 1, a plastic product placed inside the support frame 2, a cooling frame 3 fixed to the top of the bracket 1, the cooling frame 3 communicating with the inside of the bracket 1 in the direction facing inward, an opening provided at the top of the cooling frame 3, a cooling plate 4 slidably connected inside the opening, the cooling frame 3 being hollow, a rotating shaft 5 rotatably connected to the side of the cooling frame 3, a suction cup 6 fixed to the end of the rotating shaft 5 extending into the cooling frame 3, the inside of the suction cup 6 communicating with the inside of the rotating shaft, and a servo motor 7 connected to the end of the rotating shaft 5 away from the suction cup 6.

[0023] A connecting rod 8 is fixed to the top of the cooling plate 4. The connecting rods 8 are symmetrically arranged. Each connecting rod 8 is connected to a first cylinder 9 at the end away from the cooling plate 4. The two first cylinders 9 are connected in series. A support rod 10 is provided at the bottom of the two first cylinders 9. The first cylinders 9 are installed on the support rods 10. The support rods 10 are symmetrically arranged. The end of the support rod 10 away from the first cylinder 9 is fixed to the top of the bracket 1.

[0024] The cooling plate 4 is hollow inside. The end of the cooling plate 4 facing the support 1 is provided with a grid plate 11. The top of the cooling plate 4 is fixed with a telescopic water inlet pipe 12 and a telescopic water outlet pipe 13. Both the telescopic water inlet pipe 12 and the telescopic water outlet pipe 13 extend into the interior of the cooling plate 4. The extended ends are connected to a connecting pipe 15. A telescopic air pipe 14 is provided between the telescopic water inlet pipe 12 and the telescopic water outlet pipe 13. The telescopic air pipe 14 is connected to the interior of the cooling plate 4.

[0025] The cooling plate 4 achieves a cooling effect by combining cold water inside the connecting pipe 15 with air blown out by the telescopic air pipe 14. Specifically, the telescopic water inlet pipe 12 and the telescopic water outlet pipe 13 are made of telescopic pipes, and the telescopic air pipe 14 is also a telescopic pipe. When the first cylinder 9 drives the cooling plate 4 to move down, it does not affect the water inlet, water outlet and air passage. The air is circulated into the telescopic air pipe 14 through an external air pump. After the air enters the cooling plate 4, it is blown into the cooling frame 3 through the connecting pipe 15. At the same time, the first cylinder 9 can move the cooling plate 4 into the cooling frame 3.

[0026] While the gas is being introduced, cold water, specifically water below 5°C, is introduced along the telescopic water inlet pipe 12. After the cold water is introduced, it flows along the connecting pipe 15, thereby cooling the airflow outside the connecting pipe 15 and continuously introducing cold air into the cooling frame 3.

[0027] A connecting pipe 20 is fixed to the side of the rotating shaft 5, and the connecting pipe 20 is connected to the inside of the rotating shaft 5.

[0028] A second cylinder 16 is fixed at the bottom of the support frame 2. The end of the second cylinder 16 away from the support frame 2 is fixed inside the bracket 1. A guide rod 17 is also fixed at the bottom of the support frame 2. Four guide rods 17 are provided at the four corners of the support frame 2. The end of the guide rod 17 away from the support frame 2 is slidably connected inside the bracket 1.

[0029] Meanwhile, the second cylinder 16 can drive the support frame 2 to move up and down. After the plastic product is placed inside the support frame 2, the second cylinder 16 can drive the support frame 2 to move into the cooling frame 3. Combined with the aforementioned cold air, the surface of the plastic product is cooled. After the plastic product is inside the cooling frame 3, the suction cup 6 is connected to the external air pump through the connecting pipe on the side of the rotating shaft, so that the suction cup 6 can adsorb the plastic product. After the plastic product is adsorbed, the servo motor 7 drives the rotating shaft 5 to rotate back and forth, thereby allowing the plastic product to be fully cooled. When the rotating shaft 5 rotates, the external connecting pipe can switch between winding and unwinding with the rotation direction of the rotating shaft 5, thus preventing the connecting pipe from becoming messy.

[0030] Furthermore, a number of air holes 18 are provided on the inner wall of the cooling frame 3, which are evenly distributed on the inner wall of the cooling frame 3. A ventilation groove 19 is provided on the top of the cooling frame 3, and the ventilation groove 19 is connected to the interior of the cooling frame 3.

[0031] The airflow, carrying heat, flows through the vent 18 and out through the ventilation slot 19, thus preventing the accumulation of hot air inside the cooling frame 3 and improving cooling efficiency.

[0032] The working principle of this utility model is as follows: The plastic product is placed inside the support frame 2. Driven by the second cylinder 16, the support frame 2 is driven to enter the cooling frame 3 along the bottom of the cooling frame 3. At the same time, driven by the first cylinder 9, the cooling plate 4 is driven into the cooling frame 3. After the support frame 2 enters the cooling frame 3, the plastic product is fixed by suction cup 6. Gas is introduced through the telescopic air pipe 14 and then carries the cold air flow through the connecting pipe 15 to the outside of the plastic product for cooling. Driven by the servo motor 7, the plastic product can be rotated, thereby increasing the contact area of ​​the cold air and improving the cooling efficiency.
