Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.Should be understood that, embodiment described herein only, for description and interpretation the present invention, is not limited to the present invention.
Fig. 1 is the structural representation of the casting mold of one embodiment of the present invention; The casting mold of present embodiment comprises exterior sheathing 1, inner formword 2, external mold baffle plate 3, the first clamping element 6; Described inner formword 2 is nested in described exterior sheathing 1, between described inner formword 2 and described exterior sheathing 1, forms a cavity.As shown in Figure 3, for there being the open plate of a breach, and inner formword 2 is a shut to the structure of described exterior sheathing 1; Described external mold baffle plate 3 is positioned at described indentation, there, for sealing the breach of described open plate; Described the first clamping element 6 is positioned at described indentation, there, for regulating described breach size, external mold baffle plate 3 can be fixedly clamped between described breach simultaneously.Can use the adventitia baffle plate 3 of different size to adapt with the size of breach.In one embodiment, the cavity side dorsad of breach can have the convex edge that is suitable for the first clamping element 6 clampings.In another embodiment, the first clamping element 6 affixed (for example, welding or riveted joint) is in the cavity side dorsad of breach.Alternately, change inner formword in above-described embodiment 2 into open plate, as shown in Figure 4, coordinate internal mold baffle plate 4 and the second clamping element 7 to use simultaneously; Preferably, in exterior sheathing 1 and described inner formword 2, be open plate, support the use corresponding baffle plate and clamping element simultaneously, concrete structure as shown in Figure 2.By this, by clamping element, regulate the size of breach and be used in conjunction with the baffle plate of different size, having realized the adjusting to casting mold size.
Preferably, the structure of described external mold baffle plate 3 as shown in Figure 5, there is one or more through holes 9 and described casting mold and also comprise the cylinder that can insert this through hole 9, in the time of cast, cylinder can be inserted in through hole 9 completely, water and outpour the foundry goods that can communicate with the coil windings of transformer.In the obsolete situation of described through hole 9, described cylinder partly inserts in described through hole 9, prevents mould material leakage.Preferably, described through hole 9 has internal thread, and described cylinder has corresponding with it external screw thread, cylinder is screwed into the degree of depth of adjustable sealing through hole 9 in described through hole 9, has also improved the reliability of sealing.By technique scheme, use casting mold provided by the invention can directly pour into a mould out the foundry goods with through hole 9, and do not need, to the foundry goods reprocessing process such as hole, to have improved production efficiency, reduced production cost.The external mold baffle plate 3 that is provided with different through holes 9 by replacement just can be poured into a mould the foundry goods of drawing of the diverse location that communicates with the coil windings of transformer, and does not need to replace whole casting mold, has saved production cost.The use that a plurality of through holes 9 on adventitia baffle plate 3 can be selected according to actual needs simultaneously, has played the effect of saving production cost equally.
Alternatively, described casting mold also comprises overhead gage 5, is positioned at the top of described cavity, and has one or more plug holes 8, is convenient to inject mould material.In one embodiment, the shape of overhead gage 5 is consistent with the shape at cavity top.Alternatively, overhead gage 5 can be greater than the area at cavity top.
Preferably, described exterior sheathing 1 and described inner formword 2 are metal soft mode, and described metal soft mode can be stainless steel soft mode.Metal soft mode has good ductility, is convenient to the demoulding.
Preferably, in the present invention, the height of exterior sheathing 1, inner formword 2, external mold baffle plate 3 and internal mold baffle plate 4 can be identical.Alternatively, the height of exterior sheathing 1, inner formword 2, external mold baffle plate 3 and internal mold baffle plate 4 can be also different, and the coil height of cast carrys out the corresponding baffle plate of choice for use as required, and the height of exterior sheathing 1 and inner formword 2 can be higher than the height of baffle plate.
Preferably, the first clamping element 6 is identical with the second clamping element 7 structures described in clamping element of the present invention, as shown in Figure 6 and Figure 7, comprising: slotted-plate 11, has groove 13 on this slotted-plate 11; Two L-squares 12, are positioned on described slotted-plate 11, and can slide along described groove 13, have a screw 14 on each L-square 12; And the bolt 10 that passes screw 14.Alternatively, one of them of two L-squares 12 can be fixed on described slotted-plate 11, and another can slide along groove 13.Clamping element can be affixed (for example, welding or riveted joint) in the cavity side dorsad of breach, the cavity side dorsad of alternative breach can have the ,Jiang convex edge, convex edge that is suitable for clamping element clamping be clipped in two L-squares 12 between.In one embodiment, bolt 10 matches with the screw thread of screw 14, by swivel bolt 10, can make L-square 12 slide, and breach and baffle plate clamp the most at last.Bolt 10 runs through screw 14 and nut supports the use in another embodiment, realizes the slip of L-square 12, and breach and baffle plate clamp the most at last.Being free to slide of L-square 12, can be so that the installation and removal of mould.
The above-mentioned structure of having illustrated according to casting mold of the present invention; its concrete use procedure is described as follows: first described inner formword 2 can be nested in the exterior sheathing 1 being placed on rubber blanket; internal mold or external mold baffle plate 3, clamping element and overhead gage 5 are then installed; fix casting mold; then the coil windings of transformer is placed in described cavity; finally by plug hole 8, inject mould material, complete the cast of transformer coil.
Below describe by reference to the accompanying drawings the preferred embodiment of the present invention in detail; but; the present invention is not limited to the detail in above-mentioned execution mode; within the scope of technical conceive of the present invention; can carry out multiple simple variant to technical scheme of the present invention, these simple variant all belong to protection scope of the present invention.
It should be noted that in addition, each concrete technical characterictic described in above-mentioned embodiment, in reconcilable situation, can combine by any suitable mode, for fear of unnecessary repetition, the present invention is to the explanation no longer separately of various possible compound modes.
In addition, between various execution mode of the present invention, also can carry out combination in any, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
