Description
Technical field
The utility model is related to technology of die manufacturing field, more particularly to a kind of evaporative pattern positioning tool.
Background technology
Lost foam casting, also known as cavityless casting, is to make to turn into and to give birth to of EPS, STMMA or EPMMA Polymer material
Design of part, the duplicate full mold mould of size of casting are produced, drystone sand is embedded in by dip-coating fireproof coating and after drying
It is middle to pour into a mould molding flask and molten metal liquid is poured under negative pressure state through three-dimensional vibrating moulding, receive macromolecular material model
Thermal evaporation extraction, and then replaced by liquid metals, casting is formed after cooled and solidified, it is that one kind casts new work by disposal molding
Skill produces the novel casting method of casting.
Evaporative pattern uses foam mould, therefore the hardness of evaporative pattern is very low, and deformation, one are susceptible to by the effect of power
The deformation of denier evaporative pattern will influence the appearance and size and casting quality of casting.In the prior art, do not have after evaporative pattern has been made
Any safeguard procedures, therefore evaporative pattern easily deforms during storage.As shown in figure 1, a kind of evaporative pattern, its two ends
With circular port 101, the boss 102 closed up to center is provided with port 101.When the evaporative pattern is subject to the pressure of side
Port 101 can be caused to deform, circular feature disappears, influence the shape and quality of later stage casting.
Utility model content
The purpose of this utility model is to provide a kind of evaporative pattern positioning tool, can as much as possible reduce the circle of evaporative pattern
The deformation extent of port, makes port keep the shape of script.
Above-mentioned purpose of the present utility model technical scheme is that：A kind of evaporative pattern positioning tool,
Including spacing ring and keeper, keeper is triangle frame, and spacing ring is shaped as annulus, and spacing ring is provided with for by evaporative pattern
Port is fixed as the fixed part of circle.
By using above-mentioned technical proposal, spacing ring is set in the outer ring of evaporative pattern port, plays maintenance evaporative pattern port
It is shaped as the effect of circle, it is ensured that evaporative pattern its port in fixed positioning piece will not deform；The effect of keeper be by
The port shape of evaporative pattern is held round, and removes and be still difficult to deform after spacing ring and can be held round state carries out the later stage
Casting；Triangle is a kind of structure with stability, can increase the difficulty that evaporative pattern port deforms, and is substantially reduced
Deformation extent.
Preferably, fixed part is at least distributed six along the circumferential of spacing ring.
By using above-mentioned technical proposal, fixed part is evenly distributed on spacing ring, can be in evaporative pattern port
There is uniform deformation during stress, the phenomenon for reducing stress concentration causes the big degree influence of crust deformation later stage casting quality in somewhere.
Preferably, fixed part includes being arranged on the snap fit for blocking evaporative pattern port inner ring of spacing ring inner ring, snap fit
The L-type for being shaped as horizontal positioned, snap fit side long connection spacing ring.
By using above-mentioned technical proposal, the inner ring that snap fit is arranged on spacing ring is close to the boss of evaporative pattern port, multiple
Snap fit coordinates makes evaporative pattern port that micro-strain can only occur when being subject to the power to center, is not enough to change the circle of evaporative pattern port
The shape of shape or change casting.
Preferably, the short side of snap fit is connected with clamp, and clamp is set parallel to the side long of snap fit, and clamp is formed with snap fit and used
In the draw-in groove of the boss for clamping evaporative pattern.
By using above-mentioned technical proposal, draw-in groove is used to that the boss of evaporative pattern port to be clamped in interior, further raising limit
Position ring and the connection fixing of evaporative pattern port, reduce large deformation possible.
Preferably, keeper is removably connected on spacing ring.
By using above-mentioned technical proposal, keeper is removably connected and facilitates unified management to use on spacing ring,
Convenient for collecting.
Preferably, fixed part is provided with the storage tank for depositing keeper two ends.
By using above-mentioned technical proposal, keeper two ends are individually placed in storage tank, are saved keeper and are occupied unnecessary
Space, while conveniently taking.
To sum up, a kind of evaporative pattern positioning tool described in the utility model, sends out after can reducing the port stress of evaporative pattern
Raw deformation extent, makes it try one's best and is held round, so as to obtain the casting of prototype, rate of reducing the number of rejects and seconds improves casting quality.

Specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in figure 1, a kind of evaporative pattern, boss 102 is provided with port 101 of the evaporative pattern with circle and port 101,
Boss 102 closes up and with horizontal face to the center of evaporative pattern.
As shown in Fig. 2 ~ 3, a kind of evaporative pattern positioning tool, it is adaptable to evaporative pattern as depicted, including spacing ring 2.Limit
Position ring 2 is shaped as annulus, external diameter of its internal diameter more than evaporative pattern port 101.The inner ring of spacing ring 2 is uniformly distributed along its circumference
There are six fixed parts 201, the effect of fixed part 201 is that the port 101 of evaporative pattern is fixed as into circle.Fixed part 201 includes card
2011 are hooked, the L-type for being shaped as horizontal positioned of snap fit 2011, the side long of snap fit 2011 connects the inner ring of spacing ring 2.Snap fit 2011
Side upper surface long be provided with storage tank 201b for depositing keeper 3.The short side of snap fit 2011 is connected with clamp 2012, clamp
2012 parallel to snap fit 2011 side long set and with snap fit 2011 formed draw-in groove 201a, draw-in groove 201a be used for clamp evaporative pattern end
The boss 102 of mouth 101.
Evaporative pattern positioning tool also includes the keeper 3 with the dismantled and assembled connection of spacing ring 2.Keeper 3 not the used time just by it
Two ends are individually positioned in the storage tank 201b on snap fit 2011.Keeper 3 includes that three splicing bars form triangle frame.
Taken out in storage tank 201b when being shaped to evaporative pattern first by three splicing bars of keeper 3 from spacing ring 2；So
The fixed part 201 of spacing ring 2 is directed at evaporative pattern port 101 afterwards, what the snap fit 2011 and clamp 2012 for making fixed part 201 were formed
The boss 102 of draw-in groove 201a clampings evaporative pattern port 101, when now evaporative pattern port 101 is subject to side inward pressure again just
It is difficult to deform again；Three splicing bars of keeper 3 are spliced to form triangle frame again；Keeper 3 is bonded at glue finally
On the boss 102 of evaporative pattern port 101, spacing ring 2 is removed.Because the structural stability of triangle is very high, two ends are glued
Connect the evaporative pattern port 101 after keeper 3 and be just less likely to occur deformation when by side inward pressure, and circle can be kept
Shape, the model of standard is provided for the casting quality in later stage.
This specific embodiment is only that, to explanation of the present utility model, it is not to limitation of the present utility model, ability
Field technique personnel can make the modification without creative contribution to the present embodiment as needed after this specification is read, but
As long as all being protected by Patent Law in right of the present utility model.
