Abstract

The invention provides a method for manufacturing an automobile cross beam lost foam. The method comprises the following steps of: a, selecting proper STMMA beads, and detecting moisture and volatile content of the beads; b, pre-expanding: fully removing the redundant moisture from an intermittent steam pre-expander through a steam-water separation device, and then delivering the STMMA beads intothe intermittent steam pre-expander; c, curing: controlling the curing time of the beads to be between 12 and 48 hours; d, filling the cured beads into a lost foam die, and cooling and molding to obtain a lost foam I and a lost foam II; e, delivering the lost foams into a drying room; and f, inserting and connecting the lost foam I and the lost foam II together to synthesize the automobile cross beam lost foam. The method has simple process; the lost foam die has a reasonable structure; the method has low cost and high production efficiency; and the produced automobile cross beam has smooth surface and low casting defect rate.

Description

Technical field: [0001] The invention relates to the technical field of auto parts and moulds, in particular to a method for manufacturing the lost mold of an automobile beam and a method for using the same. Background technique: [0002] Automobile beam is an important part of automobile, which has the functions of support, cushioning and energy absorption. At present, the casting method of automobile crossbeam is mainly using sand casting method, that is, making the mold of automobile crossbeam with water glass sand and placing it in a sandbox. After molten steel is poured into the mold and formed, the water glass sand is scrapped, and water glass sand cannot be repeated. Using this manufacturing method, the labor intensity of the workers is high, the manufacturing cost is high, the environmental pollution is serious, and the production efficiency is low. One sandbox can only cast one automobile beam. In addition, the water glass sand mold is also easy to form casting de...
