Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a cooling water channel structure of an injection mold. Background Art

[0002] Injection molding machine is also called injection molding machine or injection machine. Many factories call it beer machine and injection products are called beer parts. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting materials. Injection molding machines can be divided into vertical, horizontal and vertical-horizontal composite types according to the arrangement of the injection device and the clamping device.

[0003] After searching, the utility model patent with patent number CN219311873U discloses a cooling water channel structure of an injection mold, and specifically discloses a movable mold insert, a nozzle insert and a water channel structure. A nozzle insert is provided in the middle of the movable mold insert, and a water channel structure is provided on the periphery of the nozzle insert, and the water channel structure partially extends into the movable mold insert. The water channel structure includes an annular water channel, and the annular water channel is provided at the outer edge of the nozzle insert. By combining the graphics and texts of the utility model patent, it can be seen that although the cooling water channel structure in the utility model patent has more pipelines, the amount of heat that water can absorb is fixed. After a part of the water absorbs more heat, it cannot continue to absorb heat. At the same time, it does not have the function of shocking raw material bubbles. There is room for improvement in practicality, so a cooling water channel structure of an injection mold is proposed to solve the above problems. Utility Model Content

The telescopic water bag is fixedly installed on the inner side of the injection mold body 1, and the convex block is fixedly installed on the top of the telescopic water bag. The telescopic water bag can automatically expand and contract according to the change of water pressure. When the water pressure increases, the convex block can be lifted up to achieve a shock effect, which can The raw material bubbles in the mold body 1 are vibrated out to improve the product quality to a certain extent. The outside of the cooling tube 2 is fixedly connected to the first water outlet pipe 5. The surrounding arrangement of the cooling tube 2 can cover a larger range of the injection mold body 1, thereby achieving a better cooling effect. A cooling box 9 is fixedly installed at the bottom of the first water outlet pipe 5, and a small water pump is fixedly installed on the inside of the cooling box 9. The small water pump can control the water pressure in the cooling tube 2, and can also make the coolant inside the cooling box 9 flow into the cooling tube 2, thereby realizing the recycling of the coolant and achieving the purpose of energy saving and environmental protection.

[0023] When in use, first inject the coolant from the water inlet pipe 6 into the cooling box 9, then the small water pump in the cooling box 9 pumps the coolant to the first water outlet pipe 5, and then enters the cooling pipe 2. After cooling, it flows back into the cooling box 9 to achieve the purpose of circulating cooling. At the same time, the telescopic water bag can be adjusted to automatically expand and contract by controlling the water pressure. When the water pressure increases, the convex block can be lifted up to have a shock effect, which can vibrate out the raw material bubbles in the injection mold body 1, thereby improving the product quality to a certain extent.

[0024] A water inlet pipe 6 is fixedly installed on the outside of the cooling pipe 2, and a water inlet head 11 is fixedly installed on the top of the water inlet pipe 6.
