Abstract
Description
Technical Field
[0001] This application relates to the field of mold head technology, and more specifically, to a mold head cooling structure that can be cooled quickly. Background Technology
[0002] The forming component of an extruder. Also known as an extrusion die or extruder head. Its function is to ensure that the molten plastic from the extruder barrel is well distributed in the die head flow channel so that it can be extruded from the die orifice at a uniform speed and formed. The forming function of the extrusion die head is crucial in the entire extrusion process. Depending on the extruded product, the structure of the extrusion die head varies, and its classification is not standardized. Generally, extrusion dies are equipped with cooling devices for heat dissipation. For example, a water cooling mechanism for an extrusion die head according to Chinese patent application number CN202220203670.3 includes a housing and a mounting plate. The inner cavity of the housing has a heat dissipation chamber. Fixed brackets are fixedly installed on the upper and lower surfaces of one side of the housing. A cooling fan is fixedly installed inside the fixed bracket. A threaded pipe is fixedly installed on one side of the housing between the two sets of fixed brackets. A water pipe is fixedly installed on one side of the housing. A sliding groove is formed on the outer surface of the mounting plate. A water tank is slidably installed on the outer surface of the mounting plate. A limit block is movably installed on the upper surface of the mounting plate. A locking block is fixedly installed on one side of the limit block. This invention improves the cooling effect of the water cooling mechanism by adding a fan and a longer delivery pipe to enhance the cooling function. It also makes the water cooling mechanism easy to disassemble and maintain, allowing it to be removed and maintained in a simple way, thus making it practical.
[0003] However, the above solution still has certain drawbacks: First, if the cooling is only done by a cooling fan, the temperature of the air blown out by the cooling fan may be high when the ambient temperature is high, resulting in poor cooling effect. Second, the cooling water may carry particulate matter during circulation, which is not easy to filter. Over time, it may clog the micro-channels inside the mold head, thereby reducing its practicality. Utility Model Content

The connecting pipe 111 and the internal sealing ring 112 are used for fitting and fixing.
[0029] In some specific implementations, a heat dissipation cavity 113 is provided inside the connecting shell 110. The heat dissipation cavity 113 can achieve a heat dissipation effect. The filter 120 includes a pipe 121, an arc-shaped plate 122, a first filter plate 123, and a second filter plate 124.

The arc plate 122 can be easily disassembled through the bolt 126 connection, so that the first filter plate 123 and the second filter plate 124 can be disassembled and cleaned.
[0030] Please see Figure 1 and Figure 4The heat dissipation assembly 200 includes a fan 210, a mounting bracket 220, and a thermoelectric cooler 230. The fan 210 is fixedly connected to one side of the support bracket 130, and the mounting bracket 220 is fixedly connected to the support bracket 130. The thermoelectric cooler 230 is fixedly connected to one side of the mounting bracket 220. The mounting bracket 220 includes a frame plate 221 and four legs 222.

The heat sinks 231 work together to enhance the heat dissipation of the hot end of the thermoelectric cooler 230 and prevent heat accumulation that would lead to a decrease in efficiency.
[0031] The working principle of this rapid-cooling die head cooling structure is as follows: In use, the connecting shell 110 is first installed on the die head. Water is pumped from inside the water tank 140 through the connecting pipe 150 to the connecting shell 110 to cool the die head. The circulating water is filtered by the first filter plate 123 and the second filter plate 124 inside the pipe 121, preventing impurities from entering the connecting shell 110 and the die head. The water inside the connecting shell 110 is then filtered again by the first filter plate 123 and the second filter plate 124 inside the pipe 121. To prevent impurities from entering the water tank 140 through the spiral tube 160, the cold end of the semiconductor cooling chip 230 is directed towards the air intake direction of the fan 210. The air drawn in by the fan 210 is first cooled by the semiconductor cooling chip 230 before being blown out, forming an active cold air delivery, which improves the heat dissipation effect of the spiral tube 160. In conjunction with several heat sinks 231, the heat dissipation of the hot end of the semiconductor cooling chip 230 is enhanced, avoiding heat accumulation that leads to a decrease in efficiency, and achieving rapid cooling. This forms cold air heat dissipation, improves the heat dissipation effect, and at the same time facilitates the filtration of circulating water, preventing blockage of the micro water channels inside the mold head, thereby improving practicality.
