[0002] In the injection molding production process, the cooling link after the injection molding part is demoulded is crucial. Injection molding is a method of injecting the heat-melted plastic material into the mold cavity under high pressure and obtaining the molded product after cooling and solidification. In this process, when the injection molding part is demoulded, its temperature is usually relatively high. If it cannot be cooled in time and effectively, a series of problems will occur. For example, it will cause the crystallinity of the material to be uneven, resulting in unstable mechanical properties, such as the indexes of strength, toughness, etc. not meeting the design requirements. Therefore, in order to ensure the quality, performance and production efficiency of the injection molding parts, the efficient, uniform and precise cooling link after demoulding is an indispensable and important part of the injection molding production.

[0003] In the injection molding production process, the cooling link after the injection molding part is demoulded is crucial. Traditional cooling methods often have problems such as low cooling efficiency and uneven cooling, which may cause defects such as deformation, dimensional deviation, and internal stress residue of the injection molding parts, thus affecting the quality and performance of the products. In addition, some cooling devices are not convenient to operate and the wastewater treatment is improper, which not only increases the production cost but also may cause certain pollution to the environment. In order to improve the production quality and efficiency of injection molding parts and meet the market demand for high-precision and high-quality injection molding products, an efficient cooling device for injection molding parts after demoulding is proposed here.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Referring to Figures 1-4 , an efficient cooling device for injection molded parts after demolding, including a cooling box 1 and an upper cover 4. The cooling box 1 serves as the main structure of the entire cooling device, providing space and a basic environment for the cooling of injection molded parts.

[0022] An installation frame 5 is provided in the cooling box 1 through a support mechanism, and the installation frame 5 plays a role of bearing and fixing. A filter screen 6 is provided on the installation frame 5, and the filter screen 6 realizes the filtering operation of the cooled water.

[0023] The upper cover 4 is connected to the cooling box 1 through a positioning mechanism. The positioning mechanism includes positioning rods 2 installed on the installation frame 5, and positioning cylinders 7 corresponding to the positioning rods 2 are installed at the bottom of the upper cover 4. Such a design can ensure the accurate docking of the upper cover 4 and the cooling box 1.

[0024] An opening 8 is provided on the upper cover 4, and a screw rod 9 is rotatably provided in the opening 8 through a driving motor. The driving motor provides power for the rotation of the screw rod 9, making the subsequent cooling operation more flexible and precise.

[0025] A moving block 10 is sleeved on the screw rod 9 in a threaded manner, and the moving block 10 is installed in the opening 8 through a limiting mechanism. The limiting mechanism includes a limiting rod 11 fixedly provided in the opening 8, and the limiting rod 11 slidably penetrates through the moving block 10. This limiting design can limit the moving block 10 to move only along the axis direction of the screw rod 9, thereby ensuring that the position adjustment of the water inlet pipe 12 can be accurately controlled.

[0026] A water inlet pipe 12 is installed through the moving block 10, and a flow dividing pipe 13 is installed at one end of the water inlet pipe 12. Cooling water is introduced through the water inlet pipe 12, and the water flow is dispersed through the flow dividing pipe 13, so as to cool the injection molded parts more comprehensively and evenly. The other end is connected to a water pump in the prior art.

[0027] The support mechanism is a support frame 14 provided in the cooling box 1, and the support frame 14 is welded to the inner wall of the cooling box 1. The welded setting ensures stability, and the support frame 14 is used to support components such as the filter screen 6.

[0028] The inner bottom wall of the cooling box 1 is inclined, and this inclined design helps the cooled waste water to converge smoothly to the drain pipe 3, facilitating drainage. An electric valve is provided in the drain pipe 3, which can conveniently control the timing and flow rate of drainage.

[0029] A lifting handle is installed on the upper cover 4, and the lifting handle is U-shaped. The U-shaped handle not only facilitates the operator to lift the upper cover 4, but also provides a more comfortable and stable grip during operation.

[0030] When the present utility model is in use, after the injection molded part is demolded, the operator opens the upper cover 4 by lifting the U-shaped handle, and places the injection molded part on the filter screen 6 of the mounting frame 5. Then, the upper cover 4 is covered. At this time, the positioning rod 2 on the mounting frame 5 is inserted into the corresponding positioning cylinder 7 at the bottom of the upper cover 4 to ensure the accurate docking of the upper cover 4 and the cooling box 1. Next, the water pump connected to the water inlet pipe 12 is started, and water flows into the flow dividing pipe 13 through the water inlet pipe 12. Under the action of the driving motor, the screw rod 9 starts to rotate. Since the moving block 10 is restricted by the limiting rod 11 and can only move along the axis direction of the screw rod 9, the water inlet pipe 12 and the flow dividing pipe 13 are driven to move. In this way, the dispersed water flow can be sprayed comprehensively and evenly on all parts of the injection molded part to achieve efficient cooling.

[0031] During the cooling process, the cooled waste water is filtered by the filter screen 6, and the impurities are left on the filter screen 6, while the waste water flows to the bottom of the cooling box 1. Since the inner bottom wall of the cooling box 1 is inclined, the waste water can smoothly converge to the drain pipe 3. When the waste water needs to be discharged, the electric valve in the drain pipe 3 is opened to control the discharge timing and flow rate of the waste water. Through the coordinated work of each component, the entire cooling process realizes uniform and efficient cooling of the injection molded part, and is convenient for operation and waste water treatment.

[0032] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and should be covered within the protection scope of the present utility model.
