Problems solved by technology

Most of the molds used are sleeve-shaped cylindrical molds. The working surface of the mold is composed of multiple leads and complex curved surfaces, which is difficult to process and manufacture.
[0003] Due to the large size of such molds, the optional processing lathes are relatively limited, and the clamping is difficult, unsafe, and the processing diameter is also limited; the forma

Example Embodiment

[0013] Example 1:

[0014] Prepare the resin prototype used to make the casting resin mold: use the design size of the casting and three-dimensional modeling software (such as Pro / E) to obtain the three-dimensional CAD model of the casting resin mold, and use the rapid prototyping mechanism to make the casting resin mold Resin prototype.

[0015] Obtain a casting resin mold for water glass self-hardening sand modeling: use the prepared resin prototype to quickly obtain the cavity of the resin casting mold by turning over the normal temperature vulcanized silicone rubber mold; in order to meet the wear resistance requirements of the mold, the mold The surface of the cavity is first coated with a layer of mixture composed of epoxy resin, curing agent, toughening agent and wear-resistant powder. The ratio of the above mixture is: epoxy resin 100 parts; curing agent 33 parts; toughening agent 10 parts; 200 parts of wear-resistant powder. The curing agent in the above raw materials is

Abstract

The invention discloses a manufacturing method of a mold for car axles. The method comprises following steps: drawing a three-dimensional CAD model based on a casting technology map of axle castings and making a resin prototype through rapid prototyping equipment; rolling over the manufactured resin prototype by a normal-temperature silicon sulfide rubber mold to rapidly obtain a mold cavity for manufacturing of the resin casting mold; providing a flat aluminum alloy plate workpiece as an aluminum alloy matrix, melting the flat aluminum alloy plate workpiece and enabling the melted alloy liquid to flow through the mold cavity; cooling the alloy liquid in the flat cavity to obtain the aluminum alloy matrix; and drilling a taper hole in the aluminum alloy matrix. The manufacturing method of the mold for car axles has following beneficial effects: the manufacture period of the mold for the car axles is effectively prolonged; and manufacturing difficulty is reduced.
