It is spacing that position is sold, it is possible to ensures that die shoe, left mould plate and right template will not occur when pouring
Relative movement.
Further, the setting height(from bottom) of two described second alignment pins is inconsistent.
The height of two described second alignment pins is inconsistent ensure that left mould plate and right template
The equal accurate positioning in two ends up and down, and then ensure that the quality of product.
Further, described tie down screw is located in described right template, and this tie down screw stretches out
Described locking disk, the other end and the spiral shell being arranged on described left mould plate are fixed in one end of right template
Hole is fixing to be connected.
Further, between described die shoe and left mould plate, right template and left mould plate is with right
Withdrawing pattern groove it is provided with between template.
By described withdrawing pattern groove, exerting oneself time conveniently stripped.
Further, described die shoe is fixed on four and above support column.
Ensure the stability of mould in casting process by this structure, improve product quality.
Further, the surface of described locking disk carries out annular knurl process.
Processed the coefficient of friction promoting locking disk by annular knurl, dress when facilitating removable mould, take
Exert oneself, and then be favorably improved production efficiency.
Further, the height of described polarity mark projection is 1mm, and described nameplate mark is convex
The height risen is 2mm.
By above-mentioned process, nameplate mark can be sunken to down pour mass plane, fully meet state's net
Physical dimension requirement.
Further, the surface of described die shoe, left mould plate and right template all carries out hard chrome plating
Process.
Being processed by hard chrome plating, compared to traditional plating chemical nickel, mold surface finish promotes
Substantially.
Further, described die shoe, left mould plate and right template all use 45# bracing members,
And in patternmaking process, carry out 40 degree of Quenching Treatment.
By above-mentioned material and process, add die hardness, reduce change in use
Shape, it is ensured that the product size of pour mass meets technological requirement.
Remarkable result of the present utility model is: simple in construction, easy to use, dress, the demoulding laborsaving,
Efficiency is high；The edge of pour mass will not be damaged, it is to avoid edge to pour mass when having poured
Incomplete；Appropriate design pattern draft, is beneficial to pour into a mould aerofluxus, and product appearance obtained preferable guarantor
Barrier, surface smoothness is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is that the A-A of Fig. 1 cuts open schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model and operation principle are made into
One step describes in detail.
As shown in Figures 1 and 2, a kind of low voltage mutual inductor casting mold, including die shoe 1 with
And it is arranged on the left mould plate 2 on this die shoe 1, right template 3, described left mould plate 2 and right mould
By being arranged at the tie down screw 4 tightening cooperation of center between plate 3, and at this locking screw
The fastening end of bar 4 is fixed with locking disk 5, when described left mould plate 2 fastens with right template 3
Charging aperture 6, described left mould plate 2 and the pattern draft of right template 3 top half is formed at top
Being 7～11 ', the pattern draft of the latter half is 1～3 °, and during owing to pouring, material is under upper filling,
The direction of opening, like horn mouth, it is simple to castable aerofluxus, in described die shoe 1
The heart is additionally provided with boss 7, and described left mould plate 2 encloses, with right template 3, the outside being located at this boss 7,
Polarity mark projection 8, secondary inserts protruding 9 and nameplate it is respectively arranged with on described boss 7
Mark protruding 10.
See accompanying drawing 1, in order to increase the coefficient of friction of described locking disk 5, to this locking circle
The surface of dish has carried out annular knurl process.
Described die shoe 1 is fixed with the first alignment pin 11, described left mould plate 2 is offered
There is the first hole, location adapted with this first alignment pin 11, described left mould plate 2 also sets
It is equipped with two second alignment pins 12, offers two second location in described right template 3 correspondence
Hole, and the setting height(from bottom) of two described second alignment pins 12 is inconsistent.
In this example, described tie down screw 4 is located in described right template 3, this tie down screw 4
Stretch out one end of right template 3 and fix described locking disk 5, the other end be arranged on described left mould
