Abstract
The invention provides a reusable memory mud core which is formed by special processing steps on the basis of the shape memory effect of memory alloy. The mud core structurally comprises a depoling rotating handle, a memory alloy spring, a locator and a cylindrical net material, wherein the depoling rotating handle is connected with the memory alloy spring, the memory alloy spring is twisted when the depoling rotating handle is rotated in the clockwise direction, and the surface area of the mud core is reduced to separate the memory mud core from a product. When the reusable memory mud core is in use, no harmful gas is generated, the ventilation property is good, and the requirements on mass and fast production are satisfied.
Description
Technical field
The present invention can be applied to the aluminium alloy casting field by reusable memory mud core, especially compressor casing of pressurizer casting.
Background technology
Automobile turbocharger is the energy-saving and emission-reduction product that improves automobile dynamic quality.The market demand is in continuous growth, and wherein the runner of aluminium alloy compressor casing product is all processed as model with disposable film covered resin sand mud core.Make this mud core power consumption, consumptive material, consumption manual work, also produce pernicious gas in the production process, indexs such as its gas forming amount, venting quality, cooldown rate all do not satisfy big production requirement.
Summary of the invention
The reusable memory mud core of the present invention's ability utilizes the SME of memorial alloy, is made through specific manufacturing procedure.The structure of its mud core is revolved handle, memorial alloy spring, locator, cylinder mesh material by depoling and is formed.Depoling is revolved being connected with the memory spring, right clockwise turn depoling the time, the memorial alloy spring is twisted, and the mud wicking surface is amassed dwindle, the mud wicking surface separates with the product runner inner wall of shaping; The memorial alloy spring is the memorial alloy mud core crab of processing by product requirement through special process with the memorial alloy wire rod; Locator is made up of with locating hole the location nail, and the location nail is installed in memorial alloy mud core crab top, and skeleton middle part one side is provided with locating hole by the figure requirement; The location nail cooperates through coating dry heat refresh memory shape with locating hole; The cylinder mesh material of memory mud core is made into memory wire, and smooth being fixed on outside the memorial alloy spring of ability possesses with the skeleton turn and dwindle surface area, reaches to make memory mud core break away from the function of product.Can reusable memory mud core in use, no pernicious gas produces, permeability is good, satisfies the demand of production fast in enormous quantities.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a shape memory vertical view of the present invention.
Fig. 3 is a depoling shape vertical view of the present invention.
The specific embodiment
Further specify below in conjunction with the accompanying drawing specific embodiments of the invention.
Comprise depoling knob (1), memorial alloy skeleton (2), the woven cylinder mesh material of memory alloy wire (3) among Fig. 1.Depoling knob (1) is placed in the openend of memorial alloy spring (2); Memorial alloy spring (2) is formed by the coiling of memorial alloy wire rod; Memorial alloy spring (2) outer cover has been sealed the woven cylinder mesh material of memory alloy wire (3).
Diagram among Fig. 2 (4), (5) are the positioners of memory mud core; Locating hole (4) is arranged on the memorial alloy spring (2); Location nail (5) is placed in the top of memorial alloy spring (2); Location nail (4) cooperates with locating hole (5) through coating dry heat refresh memory shape, and the shape memory of memory mud core meets the specification requirement of pouring into a mould compressor casing.
Fig. 3 is the shape that the reusable memory mud core of the present invention's ability can arrive when turn depoling knob (1) breaks away from product.
Fig. 2 locatees nail (4) and cooperates after coating dry heat refresh memory shape just reusable with locating hole (5).Satisfy demand of producing fast in enormous quantities.
Claims (4)
1. the reusable memory mud core of ability such as Fig. 1, shown in Figure 2 form (1), a memorial alloy spring (2), memory-alloy mesh material (3), locator (4), (5) by revolving.Comprise depoling knob (1), memorial alloy skeleton (2), the woven cylinder mesh material of memory alloy wire (3) among Fig. 1.Depoling knob (1) is placed in the openend of memorial alloy spring (2); Memorial alloy spring (2) is formed by the coiling of memorial alloy wire rod; Memorial alloy spring (2) outer cover has been sealed the woven cylinder mesh material of memory alloy wire (3).Diagram among Fig. 2 (4), (5) are the positioners of memory mud core; Locating hole (4) is arranged on the memorial alloy spring (2); Location nail (5) is placed in the top of memorial alloy spring (2); Location nail (4) cooperates with locating hole (5) through coating dry heat refresh memory shape, and the shape memory of memory mud core meets the specification requirement of pouring into a mould compressor casing.
2. according to claim 1, it is characterized in that: the skeleton (2) of memory mud core is processed by the memorial alloy spring, and the turn depoling is revolved and just can be dwindled skeleton (2) sectional area to (1), drives mud core alloy network material (3) and intactly breaks away from product, reuses.
3. according to claim 1, it is characterized in that: lining is made into by memorial alloy silk screen material (3), and the memory nerve is arranged, and revolves during depoling the elongation of (1) area, reduced cross-sectional area, is convenient to break away from product, and permeability is good.
4. according to claim 1, it is characterized in that: can process by reusable memory mud core no consumption, no pernicious gas generation, also reusable in the use by the memorial alloy genus.
