Description

Technical Field

[0001] This application relates to the technical field of automotive plastic part processing, and specifically to a cooling structure for automotive plastic part processing. Background Art

[0002] In the field of automotive plastic part processing, the performance of the cooling system directly affects the quality of plastic parts, production efficiency, and mold life. Traditional cooling structures usually use a single water pump to drive the circulation of the cooling medium, and heat exchange is carried out through fixed water channels in the mold.

[0003] For the traditional cooling structure of automotive plastic part processing, the layout of its cooling pipes is relatively simple, generally in a straight line or with a small number of bends. This layout has many drawbacks and is difficult to meet the requirements of high-quality and high-efficiency production. The flow path of the coolant on the mold surface is single and lacks sufficient coverage area, which leads to large differences in the contact time and contact area between different parts of the mold and the coolant, resulting in inconsistent cooling speeds in different regions of the mold. This uneven cooling will cause different degrees of shrinkage in the plastic parts during the molding process, and then lead to quality problems such as warping and deformation of the plastic parts, seriously affecting the dimensional accuracy and appearance quality of the product. To solve the above problems, a cooling structure for automotive plastic part processing is hereby proposed. Summary of the Invention

[0040] The present application will be further described in detail below with reference to the drawings and embodiments.

[0041] Refer to Figures 1 to 5, an embodiment of the present application provides a cooling structure for automotive plastic part processing, including a cooling water tank 1. A cooling mold assembly is arranged on one side of the cooling water tank 1. The cooling mold assembly includes an upper mold 101 and a lower mold 102, and the upper mold 101 is adapted to the lower mold 102. A cooling mechanism 5 is arranged on the surface of the cooling water tank 1. The cooling mechanism 5 includes a first water pump 501 fixedly installed on the surface of the cooling water tank 1. The output end of the first water pump 501 is connected to an upper cooling pipe 502, and the upper cooling pipe 502 is arranged on the surface of the upper mold 101. A second water pump 503 is fixedly installed on the surface of the cooling water tank 1. The output end of the second water pump 503 is connected to a lower cooling pipe 504, and the lower cooling pipe 504 is arranged on the surface of the lower mold 102. The first water pump 501 extracts coolant from the cooling water tank 1 and transports the coolant to the surface of the upper mold 101 through the upper cooling pipe 502. The coolant flows in the pipe and exchanges heat with the upper mold 101, absorbing heat. The second water pump 503 extracts coolant from the cooling water tank 1 and transports it to the surface of the lower mold 102 through the lower cooling pipe 504 for heat exchange. Moreover, the upper cooling pipe 502 and the lower cooling pipe 504 are coiled in an S shape on the upper mold 101 and the lower mold 102. The S-shaped coiling method enables the cooling pipes to cover the mold surface more widely, increasing the contact area and contact time between the coolant and the mold, so that each part of the mold can be cooled more evenly, greatly reducing quality problems such as warping and deformation of plastic parts caused by uneven cooling, and improving the dimensional accuracy and appearance quality of the product.

[0042] Referring to Figure 3 , Figure 4 and Figure 5 , in one aspect of this embodiment, a temperature reduction mechanism 4 is arranged at one end of the upper cooling pipe 502 and the lower cooling pipe 504. The temperature reduction mechanism 4 includes a temperature reduction cylinder 401. A temperature reduction column 402 is fixedly connected inside the temperature reduction cylinder 401. The temperature reduction column 402 is a hollow structure. A refrigeration component 403 is arranged at the top of the temperature reduction column 402.

[0044] The surface of the recovery pipeline 202 is provided with a filtering component 3. The filtering component 3 includes a filtering cylinder 301 arranged on the surface of the recovery pipeline 202, and the inner wall of the filtering cylinder 301 is fixedly connected with a filtering disc 302. The cooling liquid in the upper cooling pipeline 502 and the lower cooling pipeline 504 flows into the coil pipe 404. The coil pipe 404 is wound around the surface of the hollow temperature reduction column 402. The refrigeration component 403 refrigerates the inside of the temperature reduction column 402, so that the surface temperature of the temperature reduction column 402 is reduced, thereby performing secondary cooling on the cooling liquid in the coil pipe 404, capable of quickly reducing the temperature of the cooling liquid, enabling it to have good cooling capacity again, meeting the processing requirements of high-temperature plastics or plastic parts with high requirements for cooling speed, improving production efficiency. The recovery water pump 201 pumps the cooling liquid cooled by the temperature reduction mechanism 4 back to the cooling water tank 1 through the recovery pipeline 202 from the coil pipe 404, realizing the recycling of the cooling liquid. When the recycled cooling liquid passes through the recovery pipeline 202, it passes through the filtering cylinder 301, and the filtering disc 302 intercepts and filters the impurities in the cooling liquid.

[0045] Referring to Figure 3 and Figure 4 In one aspect of this embodiment, a detection mechanism 8 is arranged on the surface of the cooling water tank 1. The detection mechanism 8 includes a temperature sensor 801 fixedly installed on the upper surface of the cooling water tank 1, and the detection end of the temperature sensor 801 extends into the inside of the cooling water tank 1. A display screen 802 is fixedly installed on the surface of the cooling water tank 1.

[0046] An observation component 7 is arranged at one end of the cooling water tank 1. The observation component 7 includes an installation groove 701 penetratingly opened at one end of the cooling water tank 1, and the inner wall of the installation groove 701 is fixedly connected with an observation window 702.

[0047] Support components 6 are arranged at both ends of the lower mold 102. The support components 6 include a support frame 601 fixedly connected to one end of the lower mold 102, and a bottom block 602 is fixedly connected to one end of the support frame 601. The detection end of the temperature sensor 801 extends into the inside of the cooling water tank 1, detecting the temperature of the cooling liquid in real time and transmitting the temperature signal to the display screen 802 for display. The operator can understand the temperature condition of the cooling liquid in the cooling water tank 1 in real time, and adjust the operation parameters of the cooling system in time according to the temperature change, ensuring the stability and reliability of the cooling effect. The observation window 702 is fixed at one end of the cooling water tank 1 through the installation groove 701, and the operator can directly observe the liquid level, water quality, etc. of the cooling liquid in the cooling water tank 1 through the observation window 702. The support frame 601 is fixedly connected to one end of the lower mold 102, and the bottom block 602 is fixed at one end of the support frame 601, providing stable support for the lower mold 102.

[0048] All the electrical equipment in this solution is powered by an external power supply.

[0049] Working principle: During use, the first water pump 501 and the second water pump 503 respectively extract the coolant from the water tank, and transport it to the upper mold 101 and the lower mold 102 through the upper cooling pipeline 502 and the lower cooling pipeline 504. The S-shaped coiled pipeline covers the surface of the mold. When the coolant flows, it exchanges heat with the mold, absorbs the heat generated by the plastic part forming, realizes independent temperature control of the upper and lower molds, reduces warping deformation. The high-temperature coolant after absorbing heat flows into the coil 404 of the cooling mechanism 4, and the refrigeration component 403 cools the coolant in the coil again through the hollow cooling column 402 to restore its cooling capacity. The recycling water pump 201 pumps the cooled coolant back to the water tank 1 through the recycling pipeline 202. The filter disk 302 of the filtering component 3 intercepts impurities to ensure the cleanliness of the circulating water quality. The temperature sensor 801 detects the water temperature of the water tank in real time and displays it through the display screen 802. The operator adjusts the water pump flow or the refrigeration power according to the data; the observation window 702 is convenient for checking the water level and water quality of the water tank.
