Abstract
The utility model relates to an assembled epoxy resin casting mould for a current transformer, comprising an upper cover template, a lower cover template, a left template, a right template, a front template, a rear template, a secondary wiring template and a primary identifying module, wherein all the parts are sequentially assembled with each other to form the whole mould, and the work surface on a cavity of the mould is plated with a hard metal plating layer. The assembled epoxy resin casting mould is convenient to disassemble, high in production efficiency, good in surface rigidity, and long in service life, and has the characteristics of being good in fineness of the cavity, good in the appearance quality of products, and the like.
Description
Technical field
The utility model relates to resin filled type current transformer insulation moulding tooling device, specifically a kind of current transformer separable ring epoxy resins casting mold.
Background technology
The poured with epoxy resin mould is the main tooling device of dry type mutual inductor insulation moulding, the mold form of original cast-type mutual inductor is the middle retractable structure that is divided into two for the mould main cavity, loam cake template and lower cover template are for independently, convenient in order to guarantee curing and demolding, the draw taper of main cavity design is bigger, there is following problem in the mould of this kind structure: the mold cavity surface roughness is bigger, need smear a lot of releasing agents in the use, the long-term die deformation amount of using is big, and die life is low; Dividing mould is the mode that open-close type divides mould, and branch moulding mark mark is left in final resin solidified forming rear surface, and housing surface material sense hardness is low, easily scratches, and comprises intrinsic gradient out-of-flatness, and the product quality outward appearance is relatively poor; Adjust relatively difficulty of the position of coil in mould in the mould use; The big production efficiency of loading and unloading die worker people labour intensity is low.
The utility model content
At loading and unloading modulo operation inconvenience, the weak points such as die cavity is of poor quality, yielding, service life is low, production efficiency is poor, shaped article presentation quality difference that poured with epoxy resin mould in the prior art exists, the technical problems to be solved in the utility model provides a kind of easy to loading and unloading, production efficiency is high, case hardness good, long service life, die cavity fineness are good current transformer with separable ring epoxy resins casting mold.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The utility model current transformer has loam cake template, lower cover template, left template, right template, front template, rear pattern plate, secondary connection template and an identification module with separable ring epoxy resins casting mold, above-mentioned each parts cooperate successively and are assembled into a unitary mould, and the working surface on the mold cavity is coated with the hard coat of metal.
The left and right sides end face of left side template, right template, front template and rear pattern plate is the assembling mating surface, cooperates the location to form the main cavity of mould by the column type alignment pin each other.
Loam cake template and lower cover template periphery are provided with seam, cooperate with the upper surface and the location, lower surface of other template respectively.
Left side template, right template, front template, rear pattern plate, mutual mating surface and loam cake template, lower cover template, seam periphery are provided with the seal groove that the cross section is a rectangle), and be embedded with rubber weather strip.
The lower cover template is provided with the plug hole of rectangle, and its peripheral die cavity mask is gradient.
The utlity model has following beneficial effect and advantage:
1. easy to loading and unloading, production efficiency is high: the utility model unitary mould is to be cooperated successively by each component model to be assembled into an integral body, being fitted on the cooperation assembling is to adopt modes such as seam, alignment pin, bolt, mould handling is convenient in the use, has improved production efficiency greatly;
2. good, the long service life of case hardness: the hard coat of metal that working surface of the present utility model is coated with, effectively improved mold cavity working surface hardness, sectional die problem such as can not deform, mould utilizes the life-span effectively to be improved;
3. die cavity fineness is good, the product appearance quality is good: the utility model cast-type mold cavity surface has good surface smoothness, and does not have because the branch moulding mark mark that mould forms guarantees to water the product that outpours and has good surface quality.
Description of drawings
Fig. 1 is the utility model structural front view;
Fig. 2 is the utility model structure vertical view;
Fig. 3 is the utility model structure side view.
The specific embodiment
Below in conjunction with Figure of description the utility model is further elaborated.
Shown in Fig. 1～3, the utility model current transformer separable ring epoxy resins casting mold, has loam cake template 1, lower cover template 2, left side template 3, right template 4, front template 5, rear pattern plate 6, secondary connection template 7 and an identification module 8 (are embedded on other template, so the module of crying), above-mentioned each parts all adopt the structural carbon steel of high-quality to form by machining and the polishing of pincers worker fine gtinding, cooperate successively and be assembled into a unitary mould, working surface on the mold cavity is coated with the hard coat of metal 9, mold cavity working surface hardness is greatly improved and has good surface smoothness, be difficult for being scratched and watering the product that outpours in the use and have good surface quality; The left and right sides end face of left side template 3, right template 4, front template 5, rear pattern plate 6 is the assembling mating surface, be the phase cross surface of transformer, the intact branch moulding mark mark that can not occur of product cast, cooperate the location to form the main cavity of mould by column type alignment pin 10 each other, guarantee that product has strict dimensional accuracy; Loam cake template 1 and lower cover template 2 peripheries are provided with seam 11, cooperate with the upper surface and the location, lower surface of other template respectively, guarantee that lower plane has good flatness on the mould; Left side template 3, right template 4, front template 5, rear pattern plate 6, mutual mating surface and loam cake template 1, lower cover template 2, seam 11 peripheries are provided with the seal groove 12 that the cross section is a rectangle, during use in the rectangular seal groove setting-in rubber weather strip 13, the vacuum pouring process has reliable sealing effect, and epoxy resin influences product quality from the leakage of minute mould when having avoided cast; Lower cover template 2 is provided with the plug hole 14 of rectangle, and epoxy resin enters the passage of mould during as vacuum pouring, and its peripheral die cavity mask is gradient, and the smooth and easy of pour mass comes off when conveniently unloading modulo operation.
The utility model current transformer is a kind of novel die of following transformer production technology and associated mechanical standard design with separable ring epoxy resins casting mold, adopt the structural carbon steel of high-quality to assemble by machining and pincers worker grinding, have easy to loading and unloading, advantages such as production efficiency is high, case hardness good, long service life, die cavity fineness height, for transformer is made and quality control provides powerful guarantee in batches.
