Embodiment 1

[0007] Embodiment 1: Take the third floor beam of SH6707 luxury van as the test object.

[0008] Firstly, the process analysis was carried out, the CAD digital model was established, and the rapid prototype was processed; then the conversion model was made by using the ciba technology; finally, the qualified Bi-Sn alloy mold was manufactured by using the traditional rapid tooling technology.

[0009] The above-mentioned molds have been tested and verified by the manufacturer. The dimensional accuracy of the molds meets the technical requirements, the mold materials are stable, and the number of trial stampings meets the design requirements. It has the characteristics of short mold-making cycle and good economy, and fully meets the requirements of the factory's body trial production.

Embodiment 2

[0010] Embodiment 2: Take Xiali's secondary modified car front fender as the test object.

[0011] Firstly, the process analysis was carried out, the CAD digital model was established, and the master model made of foamed plastic was processed by numerical control; then the master model of the process was reproduced; finally, a qualified Bi-Sn alloy mold was manufactured by traditional rapid tooling technology.

[0012] The above-mentioned molds have been tested and verified by Xiali Company. The dimensional accuracy of the trial-produced parts meets the technical requirements, the mold materials are stable, and the number of trial stampings (less than 200 pieces) meets the design requirements. Low, 1 / 3 of similar molds.

Abstract

The present invention discloses a quick die-making technique, in particular, it is a high-accuracy quick die-making technique by utilizing the high-new techniques of computer, quick raw pattern manufacture and numerical control, etc. It is characterized by that it uses the new product design modulus or drawing as basis, and adpts the following steps: stamping and forming, making analysis, utilizing CAD software to design technological main model with technical supplement, then making quick raw pattern or utilizing numerical control technique to make main model by using foamed plastic as raw material, then making technological stage die, and according to the stage die casting alloy die, detecting the die, pressure testing so as to obtain the presswork.

Description

1. Technical field [0001] The invention discloses a rapid mold-making technology, in particular a high-precision rapid mold-making technology utilizing computer, rapid prototyping or numerical control and other high-tech technologies, belonging to the technical field of mold making. 2. Background technology [0002] The traditional rapid tooling is based on the prototype and adopts the copy method to manufacture the main working parts of the mold. Therefore, the prototype becomes the key to the mold manufacturing. The precision of the mold directly determines the precision of the mold. The precision of original parts remanufacturing, manual knocking or woodworking engraving is very low, which cannot meet the requirements of today's development and trial production of new products. The "obstacles" for the further development and application of traditional rapid prototyping technology. 3. Contents of the invention [0003] The object of the present invention is to overcome ...
