DETAILED DESCRIPTION

[0023] As Figures 1-5 shown, the utility model provides a technical scheme: a material head air cooling mold, including mold body 1, the bottom of mold body 1 is detachably installed with bottom cover 2, the inner wall of bottom cover 2 is fixedly installed with fan 3, the inside of mold body 1 is provided with even cooling component 4, and even cooling component 4 includes U-shaped sleeve 41, water inlet pipe 42, water outlet pipe 43, water inlet capillary 44, U-shaped inner tube 45, backwater pipe 46 and shunt sleeve 47 and support block 48.

[0024] In an embodiment of the utility model, U-shaped sleeve 41 is fixedly installed on the inner wall of mold body 1, one end outer wall of U-shaped sleeve 41 is fixedly connected with water inlet pipe 42, the other end outer wall of U-shaped sleeve 41 is fixedly connected with water outlet pipe 43, the side wall of one end of U-shaped sleeve 41 close to water inlet pipe 42 is fixedly connected with water inlet capillary 44, the end of water inlet capillary 44 is fixedly connected with U-shaped inner tube 45, one end of U-shaped inner tube 45 away from water inlet capillary 44 is fixedly connected with backwater pipe 46, shunt sleeve 47 is sleeved on the outer surface of U-shaped inner tube 45, and the arc-shaped outer wall of shunt sleeve 47 is fixedly installed with support block 48.

[0025] Further, the number of fan 3 is provided with two groups, and the two groups of fan 3 are symmetrically arranged with the vertical central axis of bottom cover 2 as the axis of symmetry, and the bottom of mold body 1 is provided with support feet, so that there is a certain gap between the bottom surface of mold body 1 and the table surface on which mold body 1 is placed, so as to facilitate the continuous work of fan 3 and take out the heat in mold body 1 through airflow, so as to achieve the effect of heat dissipation, and the number of even cooling component 4 is provided with two groups, and the two groups of even cooling component 4 are symmetrically arranged with the vertical central axis of mold body 1 as the axis of symmetry, so as to improve the overall heat dissipation and cooling efficiency of mold body 1, and can ensure the balance of heat exchange and cooling in mold body 1.

[0026] Meanwhile, the inlet pipe 42 and the outlet pipe 43 are connected to the input and output ends of the external circulating water cooling system, respectively. The circulating water cooling system is composed of common structures such as circulating pumps, circulating cooling pools, and cooling water, which are existing technologies in this field and will not be described in detail here. The circulating pump of the external circulating water cooling system pumps the cooling water in through the inlet pipe 42, while the outlet pipe 43 returns the cooled water after heat exchange to the circulating water cooling system for cooling, thereby achieving the effect of continuous cooling of the mold body 1.

[0027] Furthermore, the U-shaped inner tube 45 is disposed inside the U-shaped sleeve 41, and the shape of the U-shaped inner tube 45 is the same as that of the U-shaped sleeve 41. Simultaneously, the water inlet pipe 42 is connected to the U-shaped sleeve 41, while the connection point between the water inlet capillary tube 44 and the U-shaped sleeve 41 is located on the arc-shaped outer surface of the end of the U-shaped sleeve 41 away from its connection point with the water inlet pipe 42. This allows a portion of the cooling water entering the U-shaped sleeve 41 through the water inlet pipe 42 to be diverted into the water inlet capillary tube 44, and then into the U-shaped inner tube 45. Therefore, the cooling water inside the U-shaped sleeve 41 and the U-shaped inner tube 45 is also diverted. The water flows in opposite directions. The cooling water inside the U-shaped sleeve 41 eventually flows out through the outlet pipe 43, while the cooling water inside the U-shaped inner tube 45 flows into the return pipe 46. Specifically, the end of the return pipe 46 is connected to the outlet pipe 43 and fixedly connected. Therefore, the cooling water in the return pipe 46 is also discharged outward through the outlet pipe 43. Through the flow of cooling water in opposite directions between the U-shaped sleeve 41 and the U-shaped inner tube 45, the temperature of each part of the U-shaped sleeve 41 can be kept relatively balanced during the process of contacting the U-shaped sleeve 41 with the mold body 1 and realizing heat exchange.

[0028] It is worth noting that there are multiple sets of diversion sleeves 47, and these multiple sets of diversion sleeves 47 are evenly distributed on the arc-shaped outer surface of the U-shaped inner tube 45. At the same time, the top of the support block 48 abuts against the arc-shaped inner surface of the U-shaped sleeve 41 to maintain the posture of the U-shaped inner tube 45 within the U-shaped sleeve 41. Meanwhile, multiple sets of grooves are opened on the water-facing surface of the support block 48, and there are two sets of support blocks 48, with multiple support blocks 48 in each set. The multiple support blocks 48 are arranged in a circumferential array on the arc-shaped outer wall of the diversion sleeve 47, and the two sets of support blocks 48 are respectively located on the outer surfaces of the two ends of the diversion sleeve 47. The distribution of the two sets of support blocks 48 is staggered, thereby improving the dispersion effect of the support blocks 48 on the water flow inside the U-shaped sleeve 41, and thus improving the heat exchange efficiency between the cooling water and the mold body 1.

[0029] In an embodiment of this utility model, a turbulence component 5 is provided on the arc-shaped outer wall of the diverter sleeve 47. The turbulence component 5 includes a wave block 51, which is fixedly installed on the arc-shaped outer wall of the diverter sleeve 47. A through hole 52 is provided on the inner wall of the wave block 51.

[0030] Specifically, three sets of wave blocks 51 are arranged in a circular array and evenly distributed on the arc-shaped outer wall of the diversion sleeve 47. At the same time, the wave blocks 51 are arranged in a multi-segment curved shape, and the through hole 52 is opened at the center of the wave blocks 51. Specifically, the wave blocks 51 are arranged between two sets of support blocks 48, so that when the cooling water flows inside the U-shaped sleeve 41, the curved outer surface of the wave blocks 51 diverts and obstructs the water flow, so that the cooling water inside the U-shaped sleeve 41 can be dispersed, thereby promoting the cooling water temperature to be in a balanced state and ensuring the cooling efficiency of the device.

[0031] In this invention, during use, the ends of the inlet pipe 42 and the outlet pipe 43 are connected to the outlet and inlet of an external circulating water cooling system via pipes, respectively. After injection molding, the external circulating water cooling system is started, and the fan 3 is started simultaneously. Cooling water enters the U-shaped sleeve 41 through the inlet pipe 42 and is diverted through the inlet capillary pipe 44, allowing a portion of the cooling water to enter the U-shaped inner tube 45. Due to the opposite flow of cooling water between the U-shaped sleeve 41 and the U-shaped inner tube 45, the U-shaped sleeve 41... During the process of contacting and exchanging heat with the mold body 1, the temperature of each part of the U-shaped sleeve 41 can be kept in a relatively balanced state, thereby ensuring the relative balance of the cooling rate of each part of the mold body 1. This avoids the product inside the mold body 1 from being deformed and damaged due to excessive local cooling, thus improving the production quality and efficiency of the device. Finally, the cooling water converges at the outlet pipe 43 and flows back to the external circulating water cooling system. After complete cooling, the injection molded part inside the mold body 1 is taken out, and the mold processing work is completed.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
