Description

Technical Field

[0001] This utility model relates to the technical field of cooling plastic inserts with legs, and in particular to a cooling device for plastic inserts with legs. Background Technology

[0002] The structure of the footed insert 1 produced by the injection molding machine in a certain workshop is as follows: Figures 1-3 As shown, the insert 1 includes a plate 2, on the bottom surface of the plate 2 are two integrally formed legs 3, which are located on the front and rear sides of the plate 2 respectively. The cross-section of the two legs 3 is rectangular, and the plate 2 and the two legs 3 are both made of plastic.

[0003] Because the temperature of the insert 1 is high when it is taken out of the injection molding machine, the worker needs to cool the insert 1 before it can be transferred to the next process.

[0004] Currently, the workshop mainly uses a bellows to cool the embedded plastic part 1. The specific cooling method is as follows: the worker first puts the removed embedded plastic part 1 into the bellows 4, such as... Figure 4 As shown, the worker then turns on the fan 5 installed on the side wall of the air box 4. The airflow from the fan 5 blows towards the embedded part 1, thereby gradually cooling the embedded part 1. After the fan 5 has been working for a period of time, the worker turns off the fan 5, thus finally completing the cooling of the embedded part 1.

[0005] However, although the bellows 4 used by the workers in the workshop can cool the insert 1 that has just been taken out of the injection molding machine, it still has the following technical defects: I. The airflow exhausted by fan 5 cannot cool down the high-temperature support leg 3 in a very short time. In other words, during the cooling process, the two support legs 3 are displaced on the plate 2, that is, the position between the support leg 3 and the plate 2 is changing. However, the process requires that the position of the two support legs 3 of the insert 1 remains unchanged after the cooling time is over. Therefore, the method of using the air box 4 to cool the insert 1 in the workshop has the technical defect of low cooling quality.

[0006] II. The airflow discharged by fan 5 is all at room temperature. The temperature difference between the airflow and the temperature of the embedded part 1 is not large, which means that it takes a long time to completely cool the embedded part 1. Therefore, the method of using the air box 4 to cool the embedded part 1 in the workshop has the technical defect of low cooling efficiency.

[0007] Therefore, there is an urgent need for a cooling device that can improve the cooling quality and efficiency of embedded parts. Utility Model Content

Each horizontal through slot penetrates the left and right end faces of the strip heat conduction seat. Blind slots are provided on the front and rear sides of each horizontal through slot and are opened in the strip heat conduction seat. The distance between two blind slots is equal to the distance between two support feet of the plastic insert, and the blind slots cooperate with the support feet. An air outlet chamber communicating with its inner cavity is fixedly provided on the left side wall of the heat insulation box, and an air inlet chamber communicating with its inner cavity is fixedly provided on the right side wall of the heat insulation box.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description: like Figures 5-9 As shown, a cooling device with a support-mounted plastic insert includes a heat insulation box 6. A longitudinally arranged strip-shaped heat-conducting seat 7, which is a heat-conducting copper seat, is fixed inside the heat insulation box 6 and on its bottom surface. Multiple horizontal slots 8 are spaced apart on the top surface of the strip-shaped heat-conducting seat 7 along its length. Each horizontal slot 8 penetrates the left and right end faces of the strip-shaped heat-conducting seat 7. Blind slots 9 are provided on the front and rear sides of each horizontal slot 8, and the distance between two blind slots 9 is equal to the distance between two supports 3 of the plastic insert 1. The blind slots 9 and supports 3 are fitted together. An air outlet chamber 10 communicating with its inner cavity is fixedly provided on the left side wall of the heat insulation box 6, and an air inlet chamber 11 communicating with its inner cavity is fixedly provided on the right side wall of the heat insulation box 6. An air inlet pipe 12 is fixedly provided at the right end of the air inlet chamber 11, and a fan 13 is connected to the right end of the air inlet pipe 12. A jacket 14 is welded to the outside of the air inlet pipe 12. The jacket 14 is a heat insulation sleeve. An annular sealed cavity 15 is formed between the jacket 14 and the air inlet pipe 12. A liquid injection port is opened on the top wall of the jacket 14, and a plug 16 is plugged in the liquid injection port.

[0018] The bottom surface of the heat insulation box 6 is fixed with multiple support legs that are supported on the ground. The top surface of the strip-shaped heat-conducting base 7 has three horizontal through slots 8. The cooling device also includes a controller, which is connected to the fan 13, and the worker can control the start or stop of the fan 13 through the controller.

[0019] The method by which workers use this cooling device to cool the insert 1 that has just been taken out of the injection molding machine is as follows: S1. The worker pulls the plug 16 out of the injection port and then injects the refrigerant into the annular sealed cavity 15 between the jacket 14 and the air inlet pipe 12 through the injection port. After a certain amount is injected, the worker plugs the plug 16 back into the injection port. At this time, the refrigerant covers the air inlet pipe 12 and transfers the cooling capacity to the air inlet pipe 12. The air inlet pipe 12 then transfers the cooling capacity to its inner cavity. S2. The specific steps for installing the embedded parts are as follows: S21. The worker removes three [items] from the injection molding machine. Figures 1-3 The shown insert 1; S22. The worker inserts the two legs 3 of a plastic insert 1 into the blind grooves 9 on the front and rear sides of the first horizontal through groove 8, and supports the plate 2 of the plastic insert 1 on the top surface of the strip heat conduction seat 7, thereby realizing the installation of the first plastic insert 1. S23. The worker repeats step S22 twice to install the other two inserts 1, thus finally completing the installation of insert 1. Figures 10-12 As shown, at this time, the plate 2 of the insert 1 and the two legs 3 transfer their own heat to the strip heat-conducting seat 7; S3. The worker takes out a cover plate 17 and places it on the top surface of the heat insulation box 6, as shown. Figure 13 As shown; S4. The worker starts the fan 13 via the controller, and the fan discharges air into the air inlet duct 12. The airflow direction is as follows: Figure 14 As shown by the middle arrow, after the airflow exchanges heat with the cold air in the air inlet duct 12, the airflow becomes a low-temperature airflow below the normal temperature. Then, the low-temperature airflow enters the inner cavity of the heat insulation box 6 through the air inlet chamber 11. A part of the low-temperature airflow acts on the plate 2 of the embedded plastic part 1 to remove the heat on the plate 2. After the low-temperature airflow exchanges heat with the plate 2, the airflow is discharged to the outside of the heat insulation box 6 through the air outlet chamber 10. Meanwhile, another part of the low-temperature airflow enters the horizontal channel 8. The low-temperature airflow carries away the heat on the strip heat conduction seat 7. After the low-temperature airflow exchanges heat with the strip heat conduction seat 7, the airflow is discharged to the outside of the heat insulation box 6 through the air outlet 10. After the embedded part 1 has been cooled for a set time, the controller controls the fan 13 to turn off, thus finally achieving the cooling of the embedded part 1; S5. Removal of the cooled insert 1: The worker removes the cover plate 17 from the heat insulation box 6, and then removes the cooled insert 1 from the strip heat conduction seat 7. S6. Workers can repeat steps S2 to S5 multiple times to cool multiple batches of the insert 1.

[0020] In steps S2-S4, it is known that since the two legs 3 of the insert 1 are embedded in the blind grooves 9 on the front and rear sides of the horizontal through groove 8, the position of the legs 3 is always restricted. Therefore, when the low-temperature airflow cools the insert 1, the two legs 3 will not shift on the plate 2. Thus, this cooling device, compared to... Figure 4 The cooling method shown effectively prevents the two legs 3 from shifting during the cooling process, thereby greatly improving the cooling quality of the insert 1.

[0021] Furthermore, when the fan 13 discharges airflow into the air inlet duct 12, the airflow exchanges heat with the cold air in the air inlet duct 12, thereby turning the airflow into a low-temperature airflow below room temperature. This significantly increases the temperature difference between the low-temperature airflow and the embedded part 1, enabling the low-temperature airflow to cool the embedded part 1 in a short time. Compared to using methods such as... Figure 4 The cooling method shown greatly improves the cooling efficiency of the insert 1.
