Problems solved by technology

[0002] The melting temperature of the steel alloy mold material is relatively high, the fluidity is poor, the corrosion resistance of the cavity is not ideal, and the thermal conductivity is not high
In addition, the steel alloy manufacturing process consumes a lot of energy and pollutes the environment. It is not suitable for small batch production molds and rapid manufacturing of trial molds when enterprises develop new products.

Embodiment

[0038] 1. If figure 1 As shown, if you want to quickly make a zinc alloy mold for a shaft part, first draw a three-dimensional CAD drawing in PRO / E or other CAD software, output it as an STL format file, and input it into the data processing software of the rapid prototyping machine for processing data Processing, making a rapid prototype in the rapid prototyping machine.

[0039] 2. If figure 2 As shown, the rapid prototype 1 is placed in the mold frame 2 and fixed, the degassed liquid silicone rubber and curing agent mixture 3 is injected into the mold frame, and the mold frame is removed after curing.

[0040] 3. If image 3 As shown, use a blade to cut the silicone rubber along the predetermined parting surface, remove the rapid prototype, and obtain the upper and lower mold halves 4 and 5 at the same time.

[0041] 4. If Figure 4 As shown, place half of the silicone rubber mold in the space surrounded by the template and the mold frame, inject gypsum-type slurry or ...

Abstract

Provided are a zinc alloy mold rapid manufacture process based on rapid prototyping and a zinc alloy mold material. The method includes the steps of manufacturing of a computer aided design (CAD) model, rapid prototyping, manufacturing of a silicone rubber mold, casting, pre-burying of a cooling water channel, zinc alloy pouring, cleaning, machining, polishing and embedding to obtain the zinc alloy mold. The zinc alloy mold material comprises, by weight, 2.0-15.0% of Al, 2.0-10% of Cu, 0.01-0.05% of Mg, 0-0.1% of Re and the balance Zn.

Description

technical field [0001] The invention relates to the field of mold manufacturing, and specifically belongs to rapid mold manufacturing technology. Background technique [0002] The melting temperature of the steel alloy mold material is relatively high, the fluidity is poor, the corrosion resistance of the cavity is not ideal, and the thermal conductivity is not high. In addition, the steel alloy manufacturing process consumes a lot of energy and pollutes the environment. It is not suitable for the rapid manufacture of molds for small batch production and trial molds when enterprises develop new products. Contents of the invention [0003] The purpose of the invention is to provide a zinc alloy mold rapid manufacturing process and zinc alloy mold material based on rapid prototype. [0004] The present invention is based on rapid prototyping zinc alloy mold rapid manufacturing process and zinc alloy mold material, the steps of the method are: [0005] (1) Create a 3D CAD m...
