Embodiment Construction

[0010] Such as figure 1 , figure 2 , image 3 shown. The present invention is composed of a valve body 1, a compression spring 2, a valve stem air volume adjusting head 3, a valve stem fixing block 4, an O-shaped sealing ring 5, a locking nut 6 and multiple sets of adjusting screw rods 7. The valve body 1 is provided with an air intake channel, and the air intake channel is located at the end of the valve body 1 and is provided with an air intake nozzle, which is convenient for externally connecting the cold air pipeline. In the valve body 1, three air outlet passages are arranged according to each position of the metal mold, and a gas regulating mechanism is arranged between each of the three air outlet passages and the air inlet passage. The gas regulating mechanism is composed of a compression spring 2, a valve stem gas volume regulating head 3, a valve stem fixing block 4, an O-ring 5, a lock nut 6 and multiple sets of adjusting screw rods 7. The number of air outlet ...

Abstract

The invention provides a throttle valve device for each part of a metal die in a casting process, belongs to the technical field of a casting production process control device, and mainly solves the problems of casting defects such as shrinkage cavity, shrinkage porosity and crack of the key parts on a cast resulted from too high or too low cooling velocity which is extremely easily caused by the fact that the traditional cooling method can not accurately realize various cooling velocities required by various parts of the cast in a mold cavity of the die. The throttle valve device is mainly characterized by comprising a valve body, an air inlet channel arranged in the valve body, and an air inlet nozzle arranged at the end of the valve body; the valve body further comprises a plurality of air outlet channels arranged according to each part of the metal die, and a plurality of air adjusting mechanisms arranged between the air outlet channels and the air inlet channel. The throttle valve device has the characteristics of low manufacturing and maintaining cost, high field universality, convenience in management and flexibility in use; various cooling velocities of a plurality of parts of the same metal die are optionally realized on the same set of device; and furthermore, the throttle valve device is mainly used for cooling various metal dies.

Description

technical field [0001] The invention relates to the technical field of casting production process control equipment. Specifically relates to a throttling valve device for realizing different cooling speeds at various parts of a metal mold in a casting process. Background technique [0002] At present, in the casting production process, due to the wide variation in the local shape, wall thickness, and thermal joints of the castings, after the alloy liquid is poured into the mold cavity, in order to prevent the cooling speed of each part of the casting in the metal model cavity from failing to meet the requirements, the casting There are casting defects such as shrinkage cavity, shrinkage porosity and cracks inside. The traditional cooling method cannot accurately realize the different cooling rates required by each part of the casting in the mold cavity, which can easily lead to casting defects such as shrinkage cavities, shrinkage porosity, and cracks in key parts of the ca...
