preparation example Construction

[0021] The present inventor is a kind of preparation method utilizing 3D printing to make metal mould, and it comprises the following operation steps:

[0022] The first step: first use the computer to draw the 3D model drawings of the products to be processed;

[0023] Step 2: Input the drawn 3D model drawings into the SLA 3D printer, and the SLA 3D printer will directly print out the resin mold, and then manually repair the mold to confirm the final shape of the mold, and perform mold clamping to confirm the accuracy of the mold ;

[0024] The third step: use the silicone mold turning technology to carry out the mold turning process on the resin mold to obtain a complete and accurate silicone mold;

[0025] The fourth step: Fill the metal material on the silicone mold, and then obtain the metal mold by heating and curing; among them, heating and curing means: put it in an oven at 100-150 degrees Celsius for 30-60 minutes to cure and shape, and take out the metal mold , and...

Embodiment 1

[0034] The mass percent of each component of described metal slurry is:

[0035]

[0036] Weigh each component, and then pre-disperse with a high-speed disperser at a speed of 500r / min for half an hour. Then use a three-roll machine to disperse, coarsely disperse 1-2 times, and finely disperse 3-5 times. After the end, you can get a usable metal slurry. The performance of the metal mold after the metal paste is completely cured meets the requirements of the EVA mold.

[0037] Temperature resistance 300 degrees Celsius, pressure resistance 90kg / cm2, plus good thermal conductivity.

Abstract

The invention discloses a preparation method and a metal material for manufacturing a metal mold through 3D printing. The preparation method comprises the following steps that 1, a 3D model drawing ofa product to be processed is drawn by a computer; 2, the drawn 3D model drawing is input into an SLA 3D printer, a resin mold is directly printed by the SLA 3D printer, then manual mold trimming is carried out, the final shape of the mold is confirmed, and the mold closing processing is performed to confirm the precision of the mold; 3, silica gel turnover technology is adopted for carrying out mold turnover treatment on the resin mold, and the complete and accurate silica gel mold is obtained; and 4, metal materials fill the silica gel mold, and are heated and cured to obtain the metal mold.According to the method, a preparation method of the metal mold is manufactured through 3D printing, the required high-precision resin mold is printed by utilizing mature SLA technology in the market, the needed metal mold is cast by using a silica gel secondary turnover mold, the working efficiency is high, the labor intensity is low, and the cost is low.

Description

Technical field: [0001] The invention relates to the technical field of mold manufacturing, in particular to a preparation method and metal material for making metal molds by using 3D printing. Background technique: [0002] In the injection mold of traditional metal casting, the following process is generally adopted: first get the sample or drawing of the metal part, then start to analyze the part and generate data, then prepare the mold steel, and start rough machining of the steel first, such as grinding Plane, edge milling, drilling, etc.; after rough machining, the steel should be heat treated (some steel); after heat treatment, finish machining should be carried out according to the needs of the parts, such as surface grinding, sparking, wire cutting, CNC Gongs, etc.; after the finish machining is completed, the fitter assembles the mold, debugs it after assembly, and starts production after confirming that it meets the requirements. Above-mentioned whole process is ...
