Cooling device for magnetic steel die casting

Abstract

The invention discloses a cooling device for magnetic steel die casting. The cooling device for the magnetic steel die casting comprises a supporting frame, and the supporting device is fixedly connected with a fixed die frame through a fixed die seat. A thermometer is arranged on the front side of the fixed die frame, and a moving die seat is arranged above the fixed die frame. A cavity is formedin the middle part of the fixed die frame and the moving die seat, a water passing pipeline is arranged on the outer side of the cavity, and a water tank is arranged on one side of the supporting frame, and is connected with the water passing pipeline through a connecting pipe to convey cooling water in the water passing pipeline to a water collecting tank arranged under the supporting frame. Normal temperature water of the water collecting tank is pumped by a water pump and condensed by a condenser, then becomes low-temperature and low-pressure liquid through throttling by a throttle valve,and enters the water tank. Reusing can be achieved, water resources are saved, and a valve is arranged to control the flow rate of the cooling water and thus control the cooling rate as needed. The cooling device for the magnetic steel die casting has high cooling speed, energy saving and environmental protection, low economic cost, simple operation and high practicability, and is worth of being popularized.

Description

technical field [0001] The invention relates to the field of die-casting mold equipment, in particular to a cooling device for magnetic steel die-casting. Background technique [0002] The control of the surface temperature of the die-casting mold is very important for the production of high-quality die-casting parts. Uneven or inappropriate die-casting mold temperature will also lead to dimensional instability of the casting, and the ejection of the casting will deform during the production process, resulting in defects such as thermal pressure, sticking, surface depression, internal shrinkage cavity, and hot bubbles. Large differences in mold temperature have varying degrees of impact on variables in the production cycle, such as filling time, cooling time, and spraying time. [0003] In die-casting production, the mold temperature is very important to the internal quality and appearance of the molded product, mainly affecting the gradual internal shrinkage cavity, shrink...

Problems solved by technology

At present, the cooling method commonly used in China is direct cooling or centralized point cooling. The disadvantage is that it cannot balance the mold temperature well and is likely to reduce the service life.
