Problems solved by technology

This method is used for molds with low requirements and rough surfaces, and it can be avoided. However, for products with high dimensional accuracy and smooth surfaces, it is far from meeting the technical requirements.
The main reason for the low dimensional accuracy and rough surface is that the material crystallized under gravity has a loose structure and many defects

Embodiment Construction

[0010] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0011] The present invention consists of an air tank 1, a runner 2, a mold 3, a cover plate 4 and a runner 6 connected to the cover plate 4 for controlling the lifting of the cover plate 4. The cover plate 4 is in close contact with the gas tank 1, and the cover plate 4 on the top of the gas tank 1 is provided with a joint 5 for ventilation, and a container is placed therein. The molten alloy solution is contained in the container, and the runner 2 is arranged outside the side wall of the gas tank 1. Bottom hole is arranged, and bottom hole is corresponding with mold 3 top through holes. Runner 6 central axis is provided with thread, and this thread matches with the screw hole on the crossbeam 8 that is arranged on the support 7. A handle 9 is provided on the runner 6 .

[0012] The working principle of the invention is as follows: firstly, the mold to be made is ...

Abstract

The invention discloses a pneumatic rapid moulding device, which comprises the following parts: gas tank, wheel, mould and lid board, wherein the adaptor is set on the top of gas tank within container, the fused alloy solution is set in the container, the wheel is set on the external part of gas tank lateral wall, whose shaft end is encased on the container to pour the container, the bottom hole is opened on the gas tank, which corresponds to top through-hole of mould, the wheel is set on the lid board to control the elevation of lid board with screw on the central shaft of wheel, which mates screw hole on the beam of rack.

Description

technical field [0001] The invention relates to a mold forming device, in particular to a pneumatic rapid mold forming device. Background technique [0002] At present, in the field of rapid mold manufacturing and the like, the material around the cavity is an alloy material or plastic material with a low melting point. For a long time, people have used the method of gravity casting to pour this low-melting-point wall material into its cavity, and then handle and process it to finally form the required mold. This method can be used for molds with low requirements and rough surfaces, but it is far from meeting the technical requirements for products with high dimensional accuracy and smooth surfaces. The main reason for the low dimensional accuracy and rough surface is that the material crystallized under gravity has a loose structure and many defects. In order to completely solve this major problem in production practice, it is necessary to innovate the manufacturing metho...
