Problems solved by technology

However, the speed at which the wax injection machine sprays out liquid wax is difficult to control, accompanied by the vibration of the machine itself. Manual operation cannot cause the calibration between the wax injection port of the mold and the nozzle, which can neither guarantee product quality nor waste materials. decrease productivity
At the same time, the mode of single shooting port cannot meet the needs of synchronous processing of multiple moulds. The present invention clarifies a device with reliable structure and can solve the above problems

Abstract

The invention discloses a spray head device of a wax injection machine for precision casting. The spray head device of the wax injection machine for the precision casting comprises a shunting block, wherein a regulation cavity is formed in the shunting block, the inner wall of the top end of the regulation cavity communicates with the outside world and is provided with four slide chutes which arecentrosymmetric, a slide rod is connected in each slide chute in a sliding mode, and a valve core assembly located in the regulation cavity and used for changing the quantity of spraying outlets is arranged on each slide rod. The spray head device of the wax injection machine for the precision casting adopts a thread transmission cooperation mode, accurately controls switching between a single injection hole mode and a multiple injection hole mode, meets technical demands for synchronous processing of multiple molds, uses rotatable baffle structures symmetrically arranged in the rectangular cavity, changes the size of a gap between each two adjacent baffles to change flow speed, and meanwhile uses a control switch of a ball structure to control each baffle structure, achieves precision flow speed control by utilizing the principle that distance increase values in the horizontal direction are identical in all descending segments of the ball, and accordingly meets technical demands forthe precision casting of the wax injection machine.

Description

technical field [0001] The invention relates to the technical field of precision casting, in particular to a spray head device used for a precision casting wax injection machine. Background technique [0002] The wax pattern of precision casting is divided into artificial wax injection and mechanical wax injection during manufacture, and the nozzle of the wax injection machine is one of the most important parts of the wax injection machine. Because the solid wax needs to be melted at high temperature, it is then sprayed out from the wax injection machine. However, it is difficult to control the speed of liquid wax ejected by the wax injection machine, accompanied by the vibration of the machine itself. Manual operation cannot cause the calibration between the wax injection port of the mold and the nozzle, which can neither guarantee product quality nor waste materials. decrease productivity. At the same time, the single-shot mode cannot meet the requirement of synchronous ...
