Abstract

The invention relates to the field of car adjustors, in particular to a mould for manufacturing car adjustors and particularly provides a car adjustor mould core manufacturing method. The car adjustormould core manufacturing method comprises the steps that silica sand, a curing agent and alkaline phenolic resin are sequentially mixed to obtain alkaline phenolic resin sand, the alkaline phenolic resin sand is added into a core box of a cold core box core shooting machine to be formed and hardened, and then a mould core is taken out; the mould core is immersed into mixed cohering liquid and then taken out to be dried in air; the mould core is roasted till the temperature is 1200 DEG C or over and then cooled; and the mould core is subjected to core leach to obtain a car adjustor mould core.According to the car adjustor mould core manufacturing method, the manufacturing cost can be reduced, the heat stability of the mould core is good, the hardening time can further be shortened while it is ensured that the alkaline phenolic resin sand is sufficiently formed, the surface quality and the geometric dimension accuracy of the mould core are ensured, and the service life and manufacturing accuracy of the mould core are ensured; and the labor intensity can further be reduced, the labor condition and work environment are greatly improved, environment pollution is reduced, and energy issaved.

Description

Technical field: [0001] The invention relates to the field of automobile regulators, in particular to molds for manufacturing automobile regulators, and specifically provides a manufacturing method for mold cores of automobile regulators. Background technique: [0002] Automobile generator is the main equipment to provide electric energy. Since the rotation speed of the generator will change within a certain range, the output voltage of the generator will also change, which cannot meet the demand for constant voltage of automobile electrical appliances. Therefore, in order to make the generator The output voltage is constant and is usually equipped with an automotive regulator. Automobile regulator is a device that can adjust and control the voltage. When the speed of the automobile engine changes, the output voltage of the generator is kept stable; specifically, when the output voltage of the generator exceeds a certain value, the regulator cuts off the excitation current t...
