Description

Technical Field

[0001] This utility model relates to the field of injection molded part cooling technology, and specifically discloses a post-processing device for injection molding of household appliances. Background Technology

[0002] The outer casing of a household appliance refers to the outer casing of the appliance. Household appliances help people with tedious daily chores, improve their efficiency, and contribute to a healthy and comfortable living and working environment. With the rapid development of modern technology, household appliances have become an indispensable part of family life.

[0003] For the injection molding of home appliance casings, the injection material needs to be added between the upper and lower molds. Usually, a fixed position pouring method is used. Once the cavity between the upper and lower molds is filled, the injection pouring operation is completed. After injection molding, the molded part needs to be demolded and cooled.

[0004] Existing injection molding cooling devices mostly use unidirectional air cooling or water cooling, which leads to problems such as cooling dead zones, uneven cooling, and low cooling efficiency. Therefore, a post-processing device for household appliance injection molding is needed to solve this problem. Utility Model Content

[0005] This utility model proposes a post-processing device for household appliance injection molding. The lower cooling component directs airflow to the side wall of the workpiece, while the upper cooling component covers the top of the workpiece, forming a double-layer three-dimensional airflow network to eliminate cooling dead zones and achieve efficient and uniform cooling.

Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please see Figure 1-4 A post-processing device for injection molding of household appliances includes a cooling chamber 1 with a door, a placement mesh frame 4 with the left and right sides overlapping the upper surface of the cooling chamber 1 is placed inside the cooling chamber 1, a lower cooling component is provided on the inner wall of the cooling chamber 1, and an upper cooling component is provided on the upper surface of the placement mesh frame 4.

[0025] The lower cooling assembly includes multiple equidistant guide plates 2 fixedly connected to the inner wall of the cooling chamber 1, a guide channel 201 formed between adjacent guide plates 2, an air collection pipe 203 installed on the left and right sides of the cooling chamber 1, a first fan 204 with two air outlets respectively connected to the air collection pipe 203, and multiple air inlets 202 that penetrate the outer wall of the cooling chamber 1 and are respectively connected to the air collection pipe 203 and the guide channel 201;

[0026] The upper cooling assembly includes a top cavity 5 disposed on the upper surface of the mesh frame 4, a groove opened below the top cavity 5 and located directly above the mesh frame 4, an air collecting plate 501 installed inside the groove, an air outlet 502 penetrating through the bottom of the air collecting plate 501, and a second fan 503 installed on the upper surface of the top cavity 5 and connected to the air collecting plate 501.

[0027] In this embodiment: the two first fans 204 are operated to blow air into the air collection pipe 203, and the air enters the guide channel 201 through multiple air inlets 202. Then, the airflow is directed to the side wall of the workpiece through the guide channel 201 of the lower cooling assembly to cool the side wall of the workpiece.

[0028] The second fan 503 blows air into the air collecting plate 501, so that the air collecting plate 501 of the upper cooling component covers the top of the workpiece through the air outlet 502, forming a double-layer three-dimensional airflow network, eliminating cooling dead corners, and achieving efficient and uniform cooling.

[0029] As a technical optimization of this utility model, a cooling coil 3 is installed at the bottom of the cooling chamber 1. The input and output ends of the cooling coil 3 both penetrate and extend to the rear of the cooling chamber 1 and are connected to an external cooling medium circulation device.

[0030] In this embodiment: Cooling water is introduced into the cooling coil 3. The cooling water flows in the cooling coil 3 and actively reduces the ambient temperature of the cooling chamber 1. This, combined with the airflow cooling effect of the dual fans, significantly shortens the cooling and setting time of the injection molded part.

[0031] As a technical optimization of this utility model, the lower half of the frame 4 is a hollow mesh structure, and the diameter of its mesh holes is smaller than the minimum size of the injection molded part.

[0032] In this embodiment, by placing the lower half of the mesh frame 4 as a hollow mesh structure with a mesh diameter smaller than the minimum size of the injection molded part, the workpiece is cooled while preventing it from falling off.

[0033] As a technical optimization of this utility model, a dehumidification valve is provided on the outer wall of the cabinet door.

[0034] In this embodiment, a dehumidification valve is used to actively remove moisture generated during the cooling process.

[0035] As a technical optimization of this utility model, the upper surfaces of the cooling cavity 1 and the placement mesh frame 4 are both provided with mounting grooves, and the left and right sides of the lower surface of the top cavity 5 are fixedly connected with mounting blocks 504 that are compatible with the specifications and dimensions of the mounting grooves.

[0036] In this embodiment, the top cavity 5 can be stacked on the upper surface of the placement frame 4 through the mounting groove and mounting block 504.

[0037] As a technical optimization of this utility model, a controller is installed on the outer wall of the top cavity 5, and the first fan 204 and the second fan 503 are both electrically connected to the controller.

[0038] In this embodiment, the controller facilitates the normal operation of the first fan 204 and the second fan 503.

[0039] The working principle and usage process of this utility model are as follows: The workpiece to be cooled is placed inside the placement frame 4, and the placement frame 4 is overlapped in the cooling chamber 1. The top chamber 5 is then stacked on the upper surface of the placement frame 4 through the mounting block 504 and the mounting groove. The controller controls the two first fans 204 to work and blow air into the air collection pipe 203. The air enters the guide channel 201 through multiple air inlets 202, and then the airflow is directed to the side wall of the workpiece through the guide channel 201 of the lower cooling component to cool the side wall of the workpiece.

[0040] The second fan 503 blows air into the air collecting plate 501, so that the air collecting plate 501 of the upper cooling component covers the top of the workpiece through the air outlet 502, forming a double-layer three-dimensional airflow network, eliminating cooling dead corners and achieving efficient and uniform cooling.

[0041] Cooling water is introduced into the cooling coil 3. The cooling water flows in the cooling coil 3 and actively reduces the ambient temperature of the cooling chamber 1. This, combined with the airflow cooling effect of the dual fans, significantly shortens the cooling and setting time of the injection molded parts.
