Abstract

The utility model discloses a quick molding wax mould of a metal pipeline and belongs to the field of metal pipeline machining. The quick molding wax mould comprises a wax mould body and is characterized in that a flexible sleeve meshed with the shape of the wax mould is further arranged in the wax mould body. The quick molding wax mould for the metal pipeline is especially suitable for precision casting.

Description

Metallic conduit rapid shaping wax-pattern

Technical field

The utility model relates to the metallic conduit manufacture field, particularly a kind of metallic conduit rapid shaping wax-pattern.

Background technology

We are high in the processing request precision at present, wall is thin, complex structure, during the high metallic conduit of metallurgical mechanical property, traditional method is it to be decomposed into a plurality of parts according to the shape of metallic conduit, adopt block of metal to form all parts of metallic conduit with the method for machining, then adopt welding procedure with each parts welding fabrication, this method is so that the moulding process of parts is very complicated, and efficient is low, waste of material is serious, and the wax-pattern precision casting process is owing to having with low cost, efficient is high, and the characteristics that especially are fit to batch production have progressively substituted traditional handicraft at labyrinth metallic conduit manufacture field.

The wax-pattern hot investment casting is called again lost-wax casting or model casting, and the casting force method is:

First the foundry goods that will do is made model with wax material, and model is welded on the gate stick with same material, make module, dip in fireproof coating (mixture of waterglass or Ludox and fine sand) on the module surface, spill again fire sand, (be stained with repeatedly several of slurry, stucco, make the layer of sand enough thick), behind its dry solidification, heat to module, wax material is deviate from from cast gate, formed ghost.With the ghost roasting, making it becomes firm formwork, and metal liquid is poured into from cast gate, after the condensation, just becomes metal casting.The required precision of wax-pattern is particularly important for the wax-pattern hot investment casting.

The utility model content

For the deficiency that prior art exists, the utility model provides a kind of metallic conduit rapid shaping wax-pattern that is specially adapted to hot investment casting.

For achieving the above object, the utility model provides following technical scheme: comprise the wax-pattern body, it is characterized in that: also be provided with the used flexible bush that coincide with the wax-pattern shape in the described cere body.

During this arranges, by in the cere body, used flexible bush being set as liner, the wax-pattern that can overcome traditional structure is being made labyrinth, the deficiency that exists during the mould of multi-pipeline plane connection structure, particularly the sort of pipe end need to be reserved thicker degree in order to attack the pipeline of establishing screw thread, can make the wax-pattern of precise forming, wax-pattern by this precise forming can direct pouring goes out the pipe fitting of various labyrinths, save traditional welding of crossing meaning, the technique of polishing, and each port surface of this wax-pattern is very smooth, and because the styling of used flexible bush, common bore pipeline configuration and its inner wax-pattern tube wall bore and bore junction from large to small, cere port footpath from large to small is also sliding along seamless in can the straight forming pipeline configuration, structure, need not be again through any processing, the forming process of the wax-pattern of order casting usefulness is simplified, and dispenses the production process of counting to, and output and casting quality are improved.

Further setting of the present utility model is: described used flexible bush is close to the setting of wax-pattern inner body wall.

Mainly be smooth in order to ensure the port of wax-pattern and inwall during this arranges.

Further setting of the present utility model is: described used flexible bush is rubber sleeve.

During this arranges, adopt rubber sleeve can reach better effect, and cost is low.

The beneficial effects of the utility model are: by rubber sleeve being set as liner in wax-pattern inside, the port can be widely used in and the pipeline wax-pattern making moulding of establishing screw thread must be attacked, thereby several operation that has saved the processing wax-pattern makes the wax-pattern can the fast precise moulding.

Below in conjunction with accompanying drawing the utility model is further described:

Description of drawings

Fig. 1 is the pipeline finished product structure schematic diagram by the utility model processing;

Fig. 2 is the structural representation of the utility model embodiment;

Fig. 3 is the structural representation of the used flexible bush of the utility model embodiment;

Fig. 4 is the wax-pattern structural representation of traditional processing pipeline shown in Figure 1;

Fig. 5 is the structural representation of the ring-type short tube wax-pattern of traditional processing pipeline shown in Figure 1.

The specific embodiment

Pipeline casting finished products as shown in Figure 1, though its shape is uncomplicated, but the port of pipeline must attack and establish screw thread for the usefulness of pipeline connection, thereby, the port of its foundry goods must be reserved thicker thickness and establish screw thread in order to attack, therefore it is rather complicated on the manufacturing forming process of wax-pattern.

Such as Fig. 4, shown in Figure 5, Fig. 4 is the wax-pattern structure chart of traditional processing pipeline casting finished products shown in Figure 1, comprise position, stage casing 3, its two ends need to be nested with two ring-type short tube wax-patterns 4, in order to the thicker port in moulding two ends, this mould also need be rebuild the joint gap of the wax-pattern of pipe ends actinal surface, makes its end face smooth.The wax-pattern work flow of this structure is very complicated.

Pipeline mould such as Fig. 2, the present embodiment shown in Figure 3 comprises wax-pattern body 1, is provided with the used flexible bush 2 that shape is with it coincide in the cere body 1.

In the present embodiment, used flexible bush 2 is close to the 1 inwall setting of wax-pattern body.

In the present embodiment, used flexible bush 2 is rubber sleeve.

Wax-pattern by adopting the present embodiment to provide need not adopt two ring-type short tube wax-patterns 4 of traditional wax-pattern just can make the wax-pattern straight forming, and simple in structure, shaping speed is fast.
