Description
Technical field
The present invention relates to transformer casting mold technical field, is a kind of low voltage mutual inductor casting mold specifically.
Background technology
Transformer (instrument transformer) is the equipment of scaling transformation voltage or electric current.Its function is main
It is (5A or 1A, to refer both to high voltage or high current scaling transformation specified into normal low voltage (100V) or standard small electric current
Value), to realize the standardization of measuring instrumentss, protection equipment and automatic control equipment, miniaturization.Transformer may further be used to simultaneously
High-voltage system is separated, to ensure the safety of the person and equipment.
In traditional transformer manufacturing technology, there are problems in transformer casting mold：First, die surface is bright and clean
Degree is inadequate, pours that rear pour mass surface spikes are more, and outward appearance is bad；Second, the pattern draft design of mould is unreasonable, poured into a mould
Bubble in journey is not easy to discharge, and pours rear product surface and pit-hole be present；Third, fix using four screws and use die nut
Mold-locked is carried out, is not only wasted time and energy, it is less efficient, it is unfavorable for controlling cost of labor.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of low voltage mutual inductor casting mold, mould dress,
It is stripped laborsaving, efficiency high；The edge of pour mass will not be damaged when pouring completion, the edge to pour mass can be avoided incomplete；Close
Reason design pattern draft, is vented, product surface is highly polished, and outward appearance is good beneficial to cast.
To reach above-mentioned purpose, the technical solution adopted by the present invention is as follows：
A kind of low voltage mutual inductor casting mold, its key are：Including die shoe and the left side being arranged on the die shoe
Template, right mould plate, the tie down screw tightening between left templates and the right mould plate by being arranged at center coordinate, and at this
The fastening end of tie down screw is fixed with locking disk, and charging aperture, institute are formed at top when the left templates and right mould plate fastening
The pattern draft for stating left templates and right mould plate top half is 7~11 ', and the pattern draft of the latter half is 1~3 °, under described
The center of die holder is additionally provided with boss, and the left templates are enclosed the outside for being located at the boss with right mould plate, set respectively on the boss
It is equipped with that polarity mark is raised, secondary inserts is raised and nameplate mark is raised.
Coil windings to be cast are placed between left templates and right mould plate in the cavity formed, and by the left templates with
Right mould plate is fixed on die shoe, and then left templates and right mould plate tightening are poured into a mould, taken off afterwards by the tie down screw
Mould.This mould instead of the form manually fixed using nut on four angles by the tie down screw, twist side using hand comprehensively
Formula, hexagonal spanner in cancellation is laborsaving when not only filling, being stripped, and improves efficiency, and pulling force during demoulding does not concentrate on
The edge of pour mass and cause its incomplete；The pattern draft of mould has been subjected to rational design in addition, has not only been beneficial to cast row
Gas, ensure that pour mass is not present bubble and produces pit-hole so that the flat appearance of product, attractive in appearance, finish is higher.
Further, the first alignment pin is fixed with the die shoe, it is first fixed with this to be offered in the left templates
The first adaptable positioning hole of position pin, is additionally provided with two second alignment pins in the left templates, corresponding in the right mould plate
Offer two the second positioning holes.
By said structure, it is easy to the installation of mould, and it is spacing due to the first alignment pin and the second alignment pin, can
Ensure that die shoe, left templates and right mould plate will not relatively move when pouring.
Further, the setting height(from bottom) of two second alignment pins is inconsistent.
The height of two second alignment pins is inconsistent can to ensure that left templates and the upper and lower ends of right mould plate position
Accurately, and then it ensure that the quality of product.
Further, the tie down screw is located on the right mould plate, and one end that the tie down screw stretches out right mould plate is consolidated
The fixed locking disk, the other end are fixedly connected with the screw being arranged in the left templates.
Further, it is respectively provided between the die shoe and left templates, right mould plate and between left templates and right mould plate
There is withdrawing pattern groove.
By the withdrawing pattern groove, exerted oneself when conveniently stripped.
Further, the die shoe is fixed on the support column of more than four.
Ensure the stability of mould in casting process by the structure, improve product quality.
Further, the surface of the locking disk carries out annular knurl processing.
The coefficient of friction of lifting locking disk is handled by annular knurl, facilitates dress during removable mould, take power, and then contribute to
Improve production efficiency.
Further, the raised height of the polarity mark is 1mm, and the raised height of the nameplate mark is 2mm.
By above-mentioned processing, nameplate mark can be sunken to pour mass plane down, fully meet the physical dimension requirement of state's net.
Further, the surface of the die shoe, left templates and right mould plate carries out hard chrome plating processing.
Handled by hard chrome plating, compared to traditional plating chemical nickel, mold surface finish lifting is obvious.
Further, the die shoe, left templates and right mould plate are made of 45# steel, and are entered in patternmaking process
40 degree of Quenching Treatments of row.
By above-mentioned material and processing, die hardness is added, reduces deformation in use, ensure that pour mass
Product size meet technological requirement.
The present invention remarkable result be：It is simple in construction, it is easy to use, fill, be stripped laborsaving, efficiency high；When pouring completion not
The edge of pour mass can be damaged, is avoided incomplete to the edge of pour mass；Pattern draft has been rationally designed, has been vented beneficial to cast,
Product appearance has obtained preferable guarantee, and surface smoothness is high.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
