Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hot half mold cooling, in particular to a hot half mold high-efficiency cooling structure. Background Art
[0002] A hot half is a mold design used in plastic molding and casting processes. It is typically used in injection molding or die casting processes and is widely used in plastic injection molding, especially in products that require high precision and complex shapes. In metal casting, hot half molds can be used to improve the surface quality and detail performance of castings. Through rapid heating and cooling, the molding cycle is shortened and production efficiency is improved. Hot half molds can reduce the cooling time of the material, reduce internal stress, and improve the physical properties and surface quality of the molded part. They are suitable for a variety of materials, including thermoplastics and thermosetting plastics.
[0003] After completing the injection molding and die-casting work, it is difficult for the general hot half mold to cool down quickly, and the cooling time is long. The long cooling time can easily reduce the strength and toughness of the product inside the mold, resulting in a decline in product quality, making it difficult for the product to meet production requirements, greatly increasing the product rejection rate. At the same time, too long a cooling time will extend the product production cycle, reduce production efficiency, and reduce equipment utilization. Generally, when cooling the hot half mold, it is difficult to cool the mold evenly. When the product is subjected to uneven cooling, defects are likely to appear on the product surface, reducing the product's dimensional accuracy. In response to the above problems, an efficient cooling structure for the hot half mold is proposed to solve them. Utility Model Content

The left end of the ventilation slot 8 is connected with the interior of the heat dissipation cavity 7, which facilitates air circulation, reduces the heat inside the heat dissipation cavity 7, and effectively dissipates heat for the mold 1. A plurality of heat dissipation ports 9 are provided through the lower left end of the mold 1, and the right end of the heat dissipation port 9 is connected with the interior of the heat dissipation cavity 7. A heat dissipation fan 10 is fixedly installed inside the heat dissipation port 9 to effectively discharge the heat inside the heat dissipation cavity 7.

A temperature sensor 13 is fixedly installed at the center position of the lower inner side of the heat dissipation cavity 7 to detect the surface temperature of the heat dissipation plate 12 in real time.
[0020] Specifically, a plurality of annular cooling channels 14 are provided at the upper end of the interior of the mold 1. The coolant enters the annular cooling channel 14 to absorb heat, which can effectively cool the side of the product. A secondary liquid inlet channel 15 is provided at the center position of the right side of the annular cooling channel 14.

After absorbing the heat, the coolant will be merged into the first-level liquid discharge channel 18 through the second-level discharge channel 17, and finally discharged through the discharge pipe 6. After recycling, the cooling work continues, and the mold 1 is effectively circulated and cooled.
