Abstract

The invention discloses a cooling control method for a mold core needle of a die casting mold. The method comprises the following specific steps of: firstly introducing cooling water with pressure of 1 MPa and then introducing compressed air with pressure of 0.6 MPa for cooling and air-drying the mold core needle of the die casting mold. The invention also discloses a device for implementing the method. Compared with the prior art, the device has a simple structure and is convenient to use, and a user can set the temperature of the cooling water according to process requirements so as to maintain the temperature of the mold core needle in a certain range constantly, and therefore the product quality is improved and casting defects are reduced.

Description

technical field [0001] The invention relates to die-casting technology, in particular to a cooling control method and device for die-casting mold core pins. technical background [0002] In recent years, with the global development and emphasis on energy saving, emission reduction, and product lightweight technologies, light alloy materials such as aluminum and magnesium and their forming technologies have been rapidly developed and widely used. One of the significant development trends is that on the basis of light weight, based on the comprehensive consideration of efficiency, cost, precision, quality and mechanical properties, more and more aluminum and magnesium alloy parts are formed by die-casting technology, and the structure of die-casting parts is becoming more and more The more complex, the larger the size and the higher the precision. Therefore, the production technology of large and complex precision die castings has become a bottleneck for the further developme...
