Description

Technical Field

[0001] This utility model relates to the field of wood-plastic mold technology, and in particular to an in-mold cooling circulation system for wood-plastic molds. Background Technology

[0002] Wood-plastic molds are used to produce wood-plastic products. They are typically made of high-quality stainless steel, forged, heat-treated, and then electrically processed. Wood-plastic materials are resistant to corrosion, water, and decay, and will not rot, deform, or be attacked by pests such as ants and termites. Wood-plastic products made from these molds are widely used in outdoor landscaping, architectural decoration, and other fields.

[0003] Existing wood-plastic co-extrusion dies require cooling of the high-temperature molten material during extrusion molding. Currently, in these dies, the coolant exchanges heat with the material from only one side, resulting in short contact time between the coolant and the die and thus insufficient cooling efficiency. Furthermore, the coolant, after absorbing heat, is difficult to cool rapidly, affecting the cooling circulation rate. Therefore, this paper proposes an improved in-mold cooling circulation system for wood-plastic co-extrusion dies. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose an in-mold cooling circulation system for wood-plastic molds to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides an in-mold cooling circulation system for a wood-plastic mold, comprising a mold body, a cavity formed inside the mold body, a cooling chamber formed outside the cavity, a cooling pipe arranged around the cavity in the cooling chamber, a heat dissipation box arranged on the mold body, an exhaust pipe arranged between the heat dissipation box and the cooling pipe, and heat dissipation fins arranged on the heat dissipation box; a receiving box arranged on the mold body, a guide pipe arranged between the receiving box and the heat dissipation box, and a conveying pipe arranged between the receiving box and the cooling pipe, and a pump body arranged on the exhaust pipe, the guide pipe and the conveying pipe.

[0007] Preferably, in any of the above embodiments, the cavity is located in the middle of the mold body, and the shape of the cooling cavity matches the shape of the cavity.

[0008] The above technical solution involves a mold body that provides space for the wood-plastic composite material, with a cavity inside. During extrusion, the formed wood-plastic product is extruded from the cavity. The cavity is located in the middle of the mold body, facilitating the installation and arrangement of structures on both sides, such as cooling chambers and cooling pipes. The cooling chamber provides installation space for the cooling pipes, and its shape matches the cavity, allowing the cooling pipes to adapt to the shape of the cavity for cooling operations.

[0009] Preferably, in any of the above embodiments, the cooling pipe is arranged in a spiral structure within the cooling cavity, and there are two exhaust pipes and two heat sinks.

[0010] The above technical solution employs the following: cooling pipes provide a flow channel for the coolant, allowing it to flow along the mold cavity. The cooling pipes are arranged in a spiral pattern within the cooling cavity, ensuring that different locations within the cavity are affected by the cooling pipes. This increases the heat exchange time between the coolant and the raw material within the cavity, improving the cooling effect. Heat dissipation boxes are used to allow the heated coolant to dissipate heat outwards. Two heat dissipation boxes can dissipate heat from the coolant separately, significantly improving the coolant's heat dissipation efficiency.

[0011] Preferably, in any of the above embodiments, the two heat dissipation boxes are respectively arranged on the top and bottom surfaces of the mold body, and the drain pipe is located at the end of the cooling pipe.

[0012] The above technical solution involves two heat dissipation boxes located on the top and bottom surfaces of the mold body, allowing the coolant within each box to dissipate heat at different locations within the mold body. After being heated, the coolant flows through a drain pipe into the heat dissipation box for further cooling. Positioning the drain pipe at the end of the cooling pipe ensures sufficient heat exchange within the cooling pipe.

[0013] Preferably, of any of the above solutions, the heat dissipation fins are a plurality of fins and are evenly arranged on the heat dissipation box, and the receiving box is disposed on one side of the mold body.

[0014] The above technical solution involves: heat dissipation fins on the heat sink, which assist in heat dissipation. Several heat dissipation fins are evenly arranged to facilitate rapid heat dissipation from all parts of the heat sink. A receiving box provides space for the coolant.

[0015] Preferably, in any of the above embodiments, the guide pipe is located at the end of the heat sink, and the heat sink adopts a flat structure.

[0016] The above technical solution employs a guide pipe to direct the coolant from the heat sink to the receiving box. Positioned at the end of the heat sink, it facilitates efficient heat dissipation for the coolant within the heat sink. The heat sink features a flat structure to provide a larger surface area for the coolant, further enhancing its heat dissipation capabilities.

[0017] Preferably, in any of the above schemes, there are two guide pipes and two delivery pipes, with the guide pipe connected to the front end of the cooling pipe.

[0018] The above technical solution is adopted as follows: When performing cooling work, the pump on the delivery pipe is started, and the coolant is pumped into the cooling pipe through the delivery pipe and flows along the cooling pipe to cool the raw material in the cavity.

[0019] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. The in-mold cooling circulation system of this wood-plastic mold comprises a cooling chamber, cooling pipes, a heat dissipation box, an outlet pipe, heat dissipation fins, a receiving box, a guide pipe, a delivery pipe, and a pump. During cooling, the pump on the delivery pipe is activated, pumping coolant into the cooling pipe and allowing it to flow along the pipe to cool the material inside the mold cavity. The cooled coolant, after heat exchange, enters the heat dissipation box through the outlet pipe for further cooling. The heat dissipation fins assist the coolant in heat dissipation, improving efficiency. The cooled coolant then re-enters the delivery pipe through the guide pipe for continued cooling circulation. The cooling pipes surround the mold cavity, ensuring longer and more comprehensive contact between the coolant and the material, thus enhancing cooling efficiency. The cooled coolant, after absorbing heat, dissipates heat within the heat dissipation box, significantly increasing the cooling speed and improving the cooling circulation efficiency.

[0020] 2. The in-mold cooling circulation system of this wood-plastic mold features a cooling chamber that provides installation space for cooling pipes. The cooling chamber's shape matches the mold cavity, facilitating cooling pipe adaptation to the cavity's shape for efficient cooling. Two heat dissipation boxes allow for separate cooling of the coolant, significantly improving its heat dissipation efficiency. Numerous evenly distributed heat dissipation fins facilitate rapid heat dissipation from all areas within the heat dissipation boxes. The flat structure of the heat dissipation boxes provides a large surface area for the coolant, further aiding in heat dissipation.
