Embodiment Construction

[0018] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0019] figure 1 It is a schematic diagram of the mechanism of the wax pattern forming system in the specific embodiment of the present invention. Such as figure 1 As shown, the wax mold forming system includes a frame 1, a servo motor 2, a belt transmission device 3, a hopper 4, a variable diameter screw 5, a screw sleeve 6, a uniform temperature cylinder 7, a sensor 8, an electric control device 9, and a molding device 10 and nozzle 11.

[0020] The screw sleeve is fixed on the frame, and the variable-diameter screw is located inside the screw sleeve. The outer diameter of the thread of the variable-diameter screw is consistent with the inner diameter of the screw sleeve. The diameter of the variable-diameter screw body changes from small to large from one end to the other. The space between the...

Abstract

The invention discloses a method and system for molding wax patterns. A solid wax is conveyed into the wider end of the space between a screw sleeve and an adjustable screw. The adjustable screw rotates to shift the solid wax to the narrow end of the space between the screw sleeve and the adjustable screw. The friction among the outer side of the adjustable screw, the inner wall of the screw sleeve and the solid wax is increasing to produce heat and to melt the solid wax. The melted wax enters an even temperature cylinder and is infused into a pressing-die device through a nozzle, and then a wax pattern is formed. The method and system for molding wax patterns has the advantages that the solid wax can be directly molded into the wax pattern; the working procedure is reduced; the heating and thermal insulation for the wax are reduced; energy is saved; the automation degree of the system is high; the yield of wax pattern is high; and the system adopts electric power as the energy, utilize the advanced control system, has small noise and meets the demands for environmental protection.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a wax mold forming method and system. Background technique [0002] At present, in the precision casting industry, the first step in the precision casting is to use wax to make a wax model. The prior art is to heat the wax to 90 degrees to form liquid wax, which is added to the wax box of the wax injection machine, and the wax injection machine needs to keep the wax at a constant temperature. Before making a wax model, the wax injection machine needs to lower the wax temperature from 90 degrees to 55 to 60 degrees to form a paste wax, which is then injected into the mold to make a wax model. But this wax pattern molding method needs to consume a large amount of electric energy. Contents of the invention [0003] The object of the present invention is to provide a method and system for forming wax models, which can reduce the process of making wax models and achieve the purpose...
