Processing technology for shifting rocker arm of double vertical wax injection machine

Abstract

The invention discloses a processing technology for a shifting rocker arm of a double vertical wax injection machine. The processing technology comprises the following steps that after a mold is opened, whether a mold cavity is smooth or not, and whether edges and corners are damaged or not are checked, and whether a loose core is complete, fragile and damaged or not is checked; and wax repairingis conducted, after wax parts which are placed at room temperature of 21-26 DEG C for more than 4 hours, mold closing lines and redundant flash on the wax parts are removed with a sharp blade, meanwhile for the wax parts with obvious defects flowing into the previous process, after the confirmation of an inspector, the wax parts are transferred to workshop waste products. According to the processing technology for the shifting rocker arm of the double vertical wax injection machine, through the processes of wax repairing, tree building, fabric coating and dewaxing, the mold can accurately position a workpiece during processing, zero error in workpiece processing is achieved, meanwhile through multi-layer fabric coating process, the corrosion resistance of the workpiece is significantly improved, at the same time, a mold shell is inverted on a dewaxing trolley or quickly reach a dewaxing kettle, and the dewaxing treatment of the workpiece is achieved.

Description

technical field [0001] The invention belongs to the processing field of gear shift rocker arms, in particular to the processing technology of gear shift rocker arms of double vertical wax injection machines. Background technique [0002] Wax patterns are a common casting method. Investment casting is mainly composed of mold manufacturing, wax mold manufacturing, shell mold manufacturing and subsequent drying, roasting, pouring, solidification and other processes. The wax pattern is used to form the shape of the casting cavity. To obtain castings with high dimensional accuracy and surface finish, the wax pattern itself should first have high dimensional accuracy and surface finish. However, in the wax mold manufacturing process, the factors affecting the dimensional accuracy of the wax mold are more complicated, and there are many process parameters, so the dimensional accuracy of the wax mold varies in a relatively large range; in order to improve the production quality and...
