Abstract
The utility model provides a dry -type transformer casting mold, includes external mold, centre form, location fixing base and clamping strip, the centre form suit is in the external mold, and the both ends of centre form and external mold all set up in the fixing base of location, are provided with centre form location circular slot and external mold location annular on the terminal surface of location fixing base, and the external mold opening part between the fixing base of both ends location is provided with the clamping strip, has in the clamping strip and presss from both sides tight groove, and external mold opening both sides are all at pressing from both sides tight inslot. The utility model discloses a dry -type transformer casting mold, simple structure, the equipment is convenient with the dismantlement, has improved production efficiency, the opening both sides and the sealing strip of whole external mold all are in pressing from both sides tight groove, have prevented that the irregular deformation from appearing in the sealing strip, and be sealed effectual, has guaranteed the pouring piece quality.
Description
Technical field
The utility model relates to a kind of casting mold for dry-type transformer, belongs to transformer production technical field of mold.
Background technology
Existing dry-type transformer, its casting mold is all directly be placed in interface by sealing strip, and external mold is by screw bolt and nut fit sealing.The shortcoming of this structure is, seal is direct and pour into a mould absorption surface, and style-ability is poor; When mould and cast Workpiece clamping, there is irregular deformation in sealing strip, and the corresponding surface of the pouring piece contacted with it, also has and be out of shape vestige accordingly, also there will be most advanced and sophisticated batch cutting edge of a knife or a sword, affect electric product surface quality and electric property time serious.
Chinese patent literature CN201304699 discloses one " casting mould of epoxy ", its structure comprises internal mold, external mold, centring ring, demoulding silica gel strip, bed die and press-fits frame, internal mold and external mold upper and lower end parts are provided with centring ring, external mold opening part is provided with flange, flange and demoulding silica gel strip seal fixing, the bed die of centring ring and mold bottom is fixed, and mold integral is with drawing tie-rod.This casting mold variety of components is many, complex structure, and interior adventitia assembling and dismounting are wasted time and energy, and can not solve the problem of sealing strip irregular deformation.
Summary of the invention
For existing dry transformer pouring mould tool Problems existing, the utility model provides a kind of structure simple, easy accessibility, the dry transformer pouring mould tool of good sealing effect.
The dry transformer pouring mould tool that the utility model provides, by the following technical solutions:
This mould, comprises external mold, internal mold, location holder and clamping strip; Internal mold is sleeved in external mold, the two ends of internal mold and external mold are all arranged in the holder of location, the end face of location holder is provided with fixed internal formwork circular groove and external mold positioning ring groove, external mold opening part between the holder of location, two ends is provided with clamping strip, with clamping slot in clamping strip, external mold opening both sides are all in clamping slot.
Described internal mold is made up of steel pipe and the end cap that is welded on steel pipe two ends.
Described external mold is the cylindrical shell being provided with axially open, at least the side of opening part is provided with sealing strip.
Described location holder being provided with hold-down screw, by tightening hold-down screw, location holder being fixed on external mold.
Described clamping strip being provided with pinching screw, by tightening pinching screw, the opening both sides of external mold being adducted together.
During assembling casting mold, internal mold is sleeved in external mold, and loads onto location holder at two ends, the hold-down screw on screwed in place holder, location holder is fixed on external mold.Clamping strip is stuck in the opening both sides of external mold, tightens pinching screw, the opening both sides of external mold 1 are adducted together.
Dry transformer pouring mould tool of the present utility model, structure is simple, and assembly and disassembly are convenient, improve production efficiency; The opening both sides of whole external mold and sealing strip are all be in clamping slot, prevent sealing strip to occur irregular deformation, good sealing effect, ensure that pouring piece quality.

In figure: 1, external mold, 2, internal mold, 3, location holder, 4, hold-down screw, 5, clamping strip, 6, pinching screw, 7, sealing strip.
Detailed description of the invention
As shown in Figure 1, dry transformer pouring mould tool of the present utility model, comprises external mold 1, internal mold 2, location holder 3 and clamping strip 5.Internal mold 2 is sleeved in external mold 1, and internal mold 2 is made up of steel pipe and the end cap that is welded on steel pipe two ends, and external mold 1, for being provided with the cylindrical shell of axially open, is at least provided with sealing strip 7 in the side of opening part, and the material of sealing strip 7 can adopt silica gel.The upper and lower side of internal mold 2 and external mold 1 is provided with location holder 3, and the end face of location holder 3 is provided with fixed internal formwork circular groove and external mold positioning ring groove, and the arranged outside of location holder 3 has hold-down screw 4.Location holder 3 plays the effect of internal mold 2 in external mold 1 inner position, makes to have required cavity between internal mold 2 and external mold 1, is blocked by external mold 1 simultaneously, and by tightening hold-down screw 4, location holder 3 is fixed on external mold 1.The opening part of the external mold 1 between the holder 3 of location, top and bottom is provided with clamping strip 5, with clamping slot in clamping strip 5, opening both sides is all in the clamping slot of clamping strip 5.Clamping strip 5 is provided with pinching screw 6, by tightening pinching screw 6, the opening both sides of external mold 1 is adducted together, and by sealing strip 7, opening is sealed.Because the opening both sides of whole external mold 1 and sealing strip 5 are all be in clamping slot, prevent sealing strip 7 to occur irregular deformation, ensure that pouring piece quality.
The use procedure of above-mentioned casting mold is as described below:
Internal mold 2 is sleeved in external mold 1, and location holder 3 is loaded onto at two ends, the end of internal mold 2 is made to be in the fixed internal formwork circular groove of location holder 3, the end of external mold 1 is in the external mold positioning ring groove of location holder 3, hold-down screw 4 on screwed in place holder 3, makes location holder 3 be fixed on external mold 1.The clamping slot of clamping strip 5 is stuck in the external mold 1 opening both sides between the location holder 3 of two, top and bottom.Tighten pinching screw 6, the opening both sides of external mold 1 are adducted together, and by sealing strip 7, opening is sealed.So just by complete for whole casting mold assembling.
According to contrary process, external mold 1 can be opened and unload, pouring piece is taken out.
