Description

A kind of running gate system wax-pattern of moltening mold castings

Technical field

This utility model relates to a kind of casting wax-pattern, particularly to the running gate system wax-pattern of a kind of moltening mold castings, belongs to In Investment casting technology field.

Background technology

Model casting is also known as lost-wax casting, it is necessary first to make the product wax-pattern identical with cast shape and running gate system wax Mould is also combined, and then coats several layers of refractory material at wax pattern surface, forms shell after refractory material dry through, will bag The wax-pattern being covered with shell is placed in high steam dewaxing kettle, makes wax-pattern at high temperature be melted out, and obtains the shell of cavity, shell Shape through roasting, in the die cavity of shell, inject molten metal during cast, after cooling, i.e. obtain foundry goods.Due to the foundry goods tool obtained There are higher dimensional accuracy and surface smoothness, therefore also known as precision-investment casting.

Often running gate system wax-pattern is thicker greatly, greatly wastes wax liquid, adds production cost, reduces production effect Rate, and material process considerably increases the labor intensity of coating workman in follow-up being coated with.

Utility model content

The purpose of this utility model is, overcomes problems of the prior art, it is provided that watering of a kind of moltening mold castings Injection system wax-pattern, consumption wax is few, lightweight.

For solving above technical problem, the running gate system wax-pattern of a kind of moltening mold castings of the present utility model, including cast gate Cup wax-pattern and cross gate wax-pattern, described cup wax-pattern is up big and down small cone, and the lower end of described cup wax-pattern connects At the middle part of described cross gate wax-pattern, each termination of described cross gate wax-pattern extends along horizontal alignment external symmetry, described cup Wax-pattern is hollow circular cone tubular, and described cross gate wax-pattern is hollow-core construction.

Relative to prior art, this utility model achieves following beneficial effect: keeping running gate system wax-pattern profile not In the case of change, cup wax-pattern and cross gate wax-pattern are all made hollow-core construction, greatly reduces the consumption of wax liquid, also alleviate The weight of running gate system wax-pattern, it is simple to coating workman carries out follow-up coating operations, reduces labor intensity.

As preferred version of the present utility model, described cross gate wax-pattern is cross, and the axis of four terminations is cross Shape square crossing.

As preferred version of the present utility model, described cross gate wax-pattern is in-line, and two termination coaxial lines.

As improvement of the present utility model, described cross gate wax-pattern is hollow square-section, each end of cross gate wax-pattern It is coated with the cross gate plug of port closed respectively at Tou.It is divided into two parts to make cross gate wax-pattern, first makes hollow Cross gate, separately with little plug mould compacting cross gate plug, finally seals the port of cross gate wax-pattern with cross gate plug, With electric cautery by complete for seam crossing welding.

As further improvement of the utility model, the inner face of described cross gate plug is respectively equipped with plug step, and Each plug step is respectively embedded in the port of cross gate wax-pattern, and the outer rim of described cross gate plug is put down with the outer rim of cross gate wax-pattern Together.It is easy to cross gate plug combine with the port of cross gate wax-pattern, and both connections are relatively reliable, convenient welding.

Detailed description of the invention

As shown in Figures 1 to 5, the running gate system wax-pattern of this utility model moltening mold castings includes cup wax-pattern 1 and horizontal stroke Running channel wax-pattern 2, cup wax-pattern 1 is up big and down small cone, and the lower end of cup wax-pattern 1 is connected to cross gate wax-pattern 2 Middle part, each termination of cross gate wax-pattern 2 extends along horizontal alignment external symmetry, and cup wax-pattern 1 is hollow circular cone tubular, horizontal waters Road wax-pattern 2 is hollow-core construction.

In the case of keeping running gate system wax-pattern profile constant, cup wax-pattern 1 and cross gate wax-pattern 2 are all made sky Core structure, falls below the consumption of wax liquid significantly, also mitigates the weight of running gate system wax-pattern, it is simple to coating workman carries out follow-up Coating operations, reduces labor intensity.

Cross gate wax-pattern 2 can be cross, and the axis of four terminations is crosswise square crossing.

Cross gate wax-pattern 2 can be in-line, and two termination coaxial lines.

Cross gate wax-pattern 2 is hollow square-section, and each end of cross gate wax-pattern 2 has been covered each by port closed Cross gate plug 3.It is divided into two parts to make cross gate wax-pattern, first makes hollow cross gate, separately with little plug mould Compacting cross gate plug 3, finally seals the port of cross gate wax-pattern with cross gate plug 3, is welded by seam crossing with electric cautery Completely.

The inner face of cross gate plug 3 is respectively equipped with plug step, and each plug step is respectively embedded into cross gate wax-pattern 2 In port, the outer rim of cross gate plug 3 is concordant with the outer rim of cross gate wax-pattern 2.It is easy to cross gate plug 3 and cross gate wax-pattern 2 Port combine, and both connections are relatively reliable, convenient welding.

The foregoing is only the preferable possible embodiments of this utility model, non-therefore limit to patent of the present utility model Protection domain.In addition to the implementation, this utility model can also have other embodiments.All employing equivalents or equivalence become Change the technical scheme of formation, all fall within the protection domain of this utility model requirement.
