Problems solved by technology

[0003] At present, there are many types of V-method molds in China. Most enterprises use polyurethane molds, metal molds, wooden molds, etc. A large amount of dust generated during polyurethane mold cutting poses a great threat to the health of workers. It is difficult to punch holes in metal molds. The problem of storage and preservation of molds, and these molds have the disadvantages of being unable to recycle and high cost, especially for some small domestic manufacturers, most of their products are single-piece and small batches. Therefore, it is very important to choose suitable mold materials And the demand for cost reduction is more urgent,
[0004] In addition, many domestic enterprises produce products in the form of single-piece small batches. The types of mold materials used include metal, wood, substitute wood, and high-density boards. The common disadvantages of these molds are that the cost is too high, and they cannot be recycled. Waste molds take up a large amount of workshop area, which brings a lot of burdens to enterprises and seriously restricts the application and promotion of V-method technology in my country

Embodiment Construction

[0022] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0023] A kind of modeling mold preparation method based on paraffin wax characteristic, this method comprises the following steps:

[0024] 1) Take an appropriate amount of paraffin and put it into the crucible for melting, according to the size of the mold, use the mold to press into a block, and wait for it to cool down;

[0025] 2) Design the three-dimensional drawing according to the CAD two-dimensional drawing of the required product;

[0026] 3) Use the software to automatically plan the path, and perform processing simulation, and use the milling machine to process the paraffin rectangular block to obtain the required shape;

[0027] 4) It is drilled with a drilling machine to obtain the required mold.

[0028] The above-mentioned paraffi...

Abstract

The invention discloses a modeling mould preparation method based on the paraffin characteristics, and paraffin for mould preparation. The preparation method comprises the following steps: (1) weighing a proper amount of wax, placing the paraffin in a crucible, melting the paraffin, pressing the molten paraffin into blocks by using a mould according to the volume of the mould, and cooling the paraffin blocks; (2) designing the three-dimensional graphs according to the CAD two-dimensional graphs of a required product; (3) performing automatic route planning by using software, carrying out processing imitation, processing the paraffin rectangular blocks by a milling bed into the required shape; (4) drilling holes in the blocks by a drilling bed so as to obtain the required V-process moulds; (5) after the V-process moulds are used, placing the moulds and the waste paraffin scraps generated during the process of milling bed processing into a special paraffin container, melting the paraffin, repeating the step (1), and rapidly manufacturing V-process moulds in different shapes in sequence. The prepared paraffin moulds can be recycled, thus the production cost is reduced, the space occupied by the waste moulds is saved, and the utilization rate of factory is increased.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a method for preparing a modeling mold based on the characteristics of paraffin wax and the paraffin wax used for preparing the mold. Background technique [0002] V-method casting is a green and environmentally friendly casting method. It is developing rapidly in China and the technology is becoming more and more mature. V-method casting is a vacuum-sealed molding or negative-pressure molding casting process. The principle is to use plastic film to mold and seal the sand box. A molding method that relies on a vacuum pump to extract the air in the mold, and relies on the pressure difference between the inside and outside to make the sand particles compact to form the required cavity. [0003] At present, there are many types of V-method molds in China. Most enterprises use polyurethane molds, metal molds, wooden molds, etc. A large amount of dust generated during polyurethane mol...
