Description

Technical Field

[0001] The invention relates to the technical field of molds, and in particular to a water-cooled injection mold for a radiator fan blade and an injection molding process. Background Art

[0002] When the radiator fan is working, it accelerates the airflow by rotating rapidly, and takes away the heat through the airflow, which can play a role in rapid cooling. Therefore, the radiator fan is used in a variety of devices and systems to quickly cool down the equipment and ensure the normal operation of the equipment.

[0003] When processing and producing the fan blades of the radiator, an injection mold is needed. When the fan blade injection mold is used, the fan blade can be shaped. Moreover, the fan blade injection mold has high working efficiency, low use cost and high production quality.

[0004] During the use of the injection mold, it is necessary to wait until the inside of the mold is cooled and the product is formed before the product can be taken out. In order to accelerate the molding of the product, water cooling can be used to accelerate the cooling. For example, prior art 1 (Chinese patent with application number CN202011062323.5 and application date 2020-09-30) is a water-cooled mold, which connects the cooling hole with the return water tank, specifically improves the casting structure of the bolt hole area, reduces the influence of the center cooling on the spoke shrinkage feeding channel, and more effectively ensures the cooling of the center area of ​​the wheel to improve production efficiency;

[0005] There is also prior art 2 (application number CN201110339556.X, Chinese patent application date 2011-11-01) a mold water cooling device, which connects multiple water inlet pipes to a collecting pipe first, and then connects the collecting pipe to the water inlet, and at the same time connects multiple water outlet pipes to the collecting pipe first, and then connects the collecting pipe to the water outlet, so that the originally chaotic and complicated water inlet and outlet pipes are rearranged and arranged, which is more convenient for maintenance;

[0006] And prior art 3 (Chinese patent with application number CN201711164197.2 and application date 2017-11-21) is a combined water-cooled mold, which uses a movable and replaceable template bottom to replace the damaged bottom plate, and other parts can continue to be used, thereby improving maintenance efficiency and reducing mold use costs;

[0007] After long-term use, the temperature of the coolant itself will also rise, which will affect subsequent work. During use, the device in the above application does not have a heat dissipation structure for the coolant, which is not convenient for long-term use of the device. Based on the fact that the coolant will also rise, it can be seen that the cooling and molding speed is still low through only single water cooling. During use, the device in the above application does not have an auxiliary cooling structure, and the working efficiency is low.

[0008] In view of the above problems, it is urgent to carry out innovative design based on the original radiator fan blade water-cooled injection mold. Summary of the invention

[0026] An injection molding process of a water-cooled injection molding mold for a radiator fan blade comprises the following steps:

[0027] S1: The upper surface of the main heat sink is convex, and the end of the convex position on the upper surface of the main heat sink is inside the heat conduction groove, so that the main heat sink and the auxiliary heat sink can dissipate heat quickly. When working, after the lower mold and the upper mold are closed, the pump is started. At this time, the water inlet pipe, the side hose and the water outlet pipe work to achieve the most basic water cooling operation. When the water outlet pipe is draining, the water wheel works.

At the same time, through the rotating shaft and the stirring blade, the coolant can quickly discharge the heat into the air, which is convenient for the long-term use of the coolant. In addition, a connecting fan is provided to accelerate the circulation of the surrounding air, which also has the effect of auxiliary heat dissipation and improves the work efficiency. The specific contents are as follows:

[0032] Furthermore, the upper surface of the main heat sink is convex, and the end of the convex position on the upper surface of the main heat sink is inside the heat conduction groove, so that the main heat sink and the auxiliary heat sink can quickly dissipate heat, and when the main heat sink and the auxiliary heat sink move with the long pin, the main heat sink and the auxiliary heat sink can contact more air, so that the main heat sink and the auxiliary heat sink can better dissipate heat, thereby improving work efficiency;

[0033] Furthermore, during the movement of the long pin, the auxiliary plate plays a role of limiting, and the limiting groove and the limiting column also play a role of limiting, so that the long pin can only move in the horizontal direction;

[0034] The water-cooled injection mold of the radiator fan blade drives the rotating shaft to rotate inside the water tank through the tooth block and the connecting gear during the movement of the long pin. When the rotating shaft rotates, the stirring blade is driven to rotate synchronously. At this time, the stirring blade plays a role in shaking the coolant inside the water tank, so that the coolant can quickly discharge heat into the air, which is convenient for the long-term use of the coolant.

[0035] (3) The water-cooled injection mold of the radiator fan blade, when the shaft rotates, the end of the shaft drives the inner rod to rotate inside the side connecting plate through the bevel gear. When the inner rod rotates, the pulley drives the efficient inner rod to rotate synchronously. At this time, the connected fan is in a rotating state. When the connected fan rotates, the air flow is accelerated, which has the function of auxiliary heat dissipation.
