Problems solved by technology

In this method, the silicone rubber mold plays the role of transition conversion. The plaster type or ceramic type used to cast the metal mold is manufactured through the silicone rubber mold, and finally the metal mold is poured out of the plaster type or ceramic type, and the metal parts are finally passed through the metal mold. Casting, the molding cycle of this method is still longer, the manufacturing cost is higher, which is not conducive to the manufacture of single-piece or small-batch molds

Embodiment 1

[0024] The method for utilizing the silica gel mold to produce parts of the present invention comprises the following steps:

[0025] A. Mold master sample preparation: first remove the processing burrs of the master sample, fill the surface and polish it until smooth, and mark the parting surface with tape;

[0026] B. Production of mold frame and placement of parts samples: the material of the mold frame is cut according to the geometric size of the part sample by adding 20mm on one side to build a square mold frame, and the parts samples are fixed in the mold frame, and ABS rods are taken Fixed in the mold frame, the ABS rod penetrates into the gap of the part;

[0027] C. Silica gel treatment and vacuum injection molding: Weigh liquid silica gel, add curing agent and mix evenly, and vacuumize and degas; Solidify at ℃, then stand and cool to 18-25℃;

[0028] D. Mold opening: Remove the mold frame, draw a wavy line on the parting surface, cut the mold along the wavy line, ...

Abstract

The invention discloses a method for producing parts by utilizing a silicon mould. The method comprises the two steps of silicon mould manufacture and part duplication, wherein silicon mould manufacture comprises the steps of mould master template preparation, mould frame manufacture and part sample piece placement, silicon treatment and vacuum casting, demoulding and the like; and part duplication comprises the steps of mould preparation, AB material treatment and vacuum casting, demoulding and part fetching, duplicated part posttreatment and the like. The method has the advantages that the manufacture cycle is short; the part manufacture quality is high; and multiple parts can be obtained in a short time, so that requirement of early-stage verification work can be met.

Description

technical field [0001] The invention belongs to the field of mold processing and manufacturing, in particular to a method for producing parts by using a silicone mold. Background technique [0002] RP technology is the abbreviation of rapid prototyping technology, also known as rapid prototyping technology, and it and RM (rapid tooling) technology are playing an increasingly important role in modern manufacturing. Silicone rubber molds in RM technology are mainly used to produce parts in small batches. And the preparation method of existing silicone rubber mold is to make prototype with RP technology earlier, then use this prototype to reproduce silicone rubber mold. This method is time-consuming and expensive. [0003] Chinese Patent Publication No. CN1270859A, published on October 25, 2000, discloses a process method for rapidly manufacturing metal molds. The method first uses three-dimensional modeling software such as Pro / Engineer, Unigraphic-II, and Powershape to desi...
