Method for manufacturing an aluminum alloy rod head

Abstract

A method for manufacturing an aluminum alloy rod head, wherein an aluminum alloy material is placed in molds of a panel, an upper cover, and a bottom plate; and then the molds are mold-cast to be formed as casings. The inner surfaces of the casings are installed with transversal enhancing bodies and longitudinal enhancing bodies. Therefore, the weight can be controlled easily and the ratio of the thickness thereof is also controlled easily. Moreover, the mold can be removed conveniently. Then, the connections of the casings are welded to be formed as a super large (above 330CC) rod head.

What is claimed is:  
     
         1 . A method for manufacturing an aluminum alloy rod head, wherein an aluminum alloy material is place in molds of a panel, an upper cover, and a bottom plate; and then the molds are mold-cast to be formed as casings of a rod head, then, connections of the casings are welded to be formed as a super large rod head.  
     
     
         2 . The method for manufacturing an aluminum alloy rod head as claimed in  claim 1 , wherein the aluminum alloy material rod head is formed by a panel, an upper cover and a bottom plate; wherein an upper and a lower side of the back side of the panel are protruded with transversal enhancing bodies; the upper and lower transversal enhancing bodies are combined to be formed with a central recess two sides of which are installed with longitudinal enhancing bodies and for removing the molds; an inner surface of the upper cover near the two sides is downwards protruded with transversal enhancing bodies; and an inner surface of the bottom plate near the two sides are protruded upwards with transversal enhancing bodies.  
     
     
         3 . The method for manufacturing an aluminum alloy rod head as claimed in  claim 1 , wherein the longitudinal and transversal enhancing bodies on the back sides of the panel are crossed across one another so as to increase the strength of the panel.
