Abstract

The utility model discloses a kind of investment pattern precision casting de-waxing, blast, cooling device, include chamber mould and plug, the upper end of chamber mould and plug has flange respectively, and plug is up big and down small bullet, and the inner chamber of chamber mould is the up big and down small conical cavity matched with plug.The utility model structure is simple, can play and ensure that de-waxing is unobstructed to prevent shell from cracking, to remove roasting rear profile shell cavity residual ash and ensure that foundry goods realizes the effect towards consecutive solidification three aspect in cast gate direction.

Description

Investment pattern precision casting de-waxing, blast, cooling device
Technical field
The utility model relates to precision-investment casting field, specifically a kind of investment pattern precision casting de-waxing, blast, cooling device.
Background technology
Along with the development of melted module precise casting technology, adopt precision-investment casting produce product get more and more, interiors of products quality and dimension precision requirement more and more higher.Precision-investment casting production process is relatively various, particularly shell processed, the having the greatest impact of smelter's ordered pair casting quality, how to ensure dewaxing de-waxing unobstructed be unlikely wax liquid expand be split up shell, how to ensure roasting after shell die cavity is effectively cleared up, how to ensure casting pouring after realize towards rising head direction consecutive solidification be produce the key of castings.Thin-walled transmission butterfly plate is typical precision castings, its appearance profile size is larger, intermediate cavity transmission, from casting structure, thick large, the middle wall thickness in foundry goods two ends is thinner, when being unfavorable for dewaxing wax liquid flow out smoothly and pouring metal melt time dead head order feeding, easily cause wax liquid to be split up shell shell and bottom cast gate root shrinkage defect.The processing of butterfly plate external diameter sphere has not allowed any casting flaw, traditional technological design is sprue direct feeding formula pouring technology, bottom does not add this device, whole like this shell die cavity only has cup one outlet, shell dewaxing time butterfly plate bottom thick large part wax liquid cannot flow out smoothly cause shell produce micro-crack, a small amount of ash content after Baking in die cavity cannot be removed, easily produce " stain " defect when butterfly plate external diameter sphere is processed, this defect fine finishining scrappage is higher, has had a strong impact on product and has handed over the phase.
Utility model content
The purpose of this utility model is the defect in order to make up prior art, a kind of investment pattern precision casting de-waxing, blast, cooling device are provided, effectively can ensure that bottom foundry goods, thick most wax liquid flows out smoothly from blow hole when dewaxing, wax liquid can not be caused to be split up shell, to make the shell mold cavity surface shell after dewaxing complete smooth non-microcracked.
The technical solution of the utility model is as follows:
A kind of investment pattern precision casting de-waxing, blast, cooling device, include chamber mould and plug, it is characterized in that: the upper end of described chamber mould and plug has flange respectively, described plug is up big and down small bullet, and the inner chamber of described chamber mould is the up big and down small conical cavity matched with described plug.
Described investment pattern precision casting de-waxing, blast, cooling device, is characterized in that: described chamber die welding is connected on the foundry goods side relative to cast gate.
The beneficial effects of the utility model:
The utility model structure is simple, can play and ensure that de-waxing is unobstructed to prevent shell from cracking, to remove roasting rear profile shell cavity residual ash and ensure that foundry goods realizes the effect towards consecutive solidification three aspect in cast gate direction.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is thin-walled transmission butterfly plate use case group tree sketch of the present utility model.
Detailed description of the invention
See Fig. 1, a kind of investment pattern precision casting de-waxing, blast, cooling device, include chamber mould 1 and plug 2, the upper end of chamber mould 1 and plug 2 has flange 3 respectively, plug 2 is up big and down small bullet, and the inner chamber 4 of chamber mould 1 is the up big and down small conical cavity matched with plug 2.
In the utility model, chamber mould 2 is welded on foundry goods 7 side relative to cast gate 5, in order to form corresponding blow hole 6.
See Fig. 2, chamber mould 1 and plug 2 need first to make metal die respectively in order to make corresponding wax-pattern, the wax-pattern that chamber mould 1 makes needs independent coating (a coating inner chamber) in order to form corresponding plug shell mould, plug shell mould needs prior roasting fully and to be cooled to normal temperature for subsequent use, blow hole 6 needs when stifled going the adhesive coating thin layer in advance at plug shell mould flange place, then also pressing is tight to insert rapidly blow hole 6, to ensure that shell has enough intensity and meets cast requirement.

Claims (2)

1. an investment pattern precision casting de-waxing, blast, cooling device, include chamber mould and plug, it is characterized in that: the upper end of described chamber mould and plug has flange respectively, described plug is up big and down small bullet, and the inner chamber of described chamber mould is the up big and down small conical cavity matched with described plug.
2. investment pattern precision casting de-waxing according to claim 1, blast, cooling device, is characterized in that: described chamber die welding is connected on the foundry goods side relative to cast gate.
