Description
Technical field
The present invention relates to cable accessory preparation field more particularly to voltage class 10kV~110kV cable shrinkages or prefabricated
Formula is indoor, outdoor terminal production mould.
Background technique
In mesolow, HV cable accessories field, cold-shrink type, prefabrication type cable accessory are latest generation technologies, it is wrapped and
Pyrocondensation is more preferable, and electric property and enclasping force are more longlasting.However, cold-shrink type, prefabrication type cable accessory have one it is distant lack
Point is exactly that a longitudinal molding is stitched, and after formed product, molding the overlap sewed on must be torn.
Having vertical or horizontal molding seam on product is determined by existing production technology and production mould, existing production
Mold either closes film still left and right molding up and down, is all to close film using the mold as two pieces to be poured, and in casting process
In be all horizontal positioned molding (with reference to Fig. 1).
Castable is through certain temperature in mold during casting, and pressure, time molding, surface is smooth, point
Sulfidization molding is thorough between son, combines between molecule sufficiently stable.But in tear place, the performance of molecular motion is entirely different,
The substance of molecular level can be released at any time inside silica gel, and can constantly be increased with its runing time, to influence product
Electric property causes to climb even breakdown outside product when serious.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, provide a kind of scientific structure design, use
Handstand pouring type facilitates umbrella point to be vented, a kind of outdoor terminal mold of no longitudinal molding seam.
To realize the present invention the following technical schemes are provided:
A kind of outdoor terminal mold without longitudinal molding seam, mainly include upper die holder, lower die holder, mold core and several be stacked
Circle module between upper die holder and lower die holder；Through-hole is arranged in the upper die holder center, and hole, the circle are supported in the setting of lower die holder center
Module is annular shape, and insertion is supported in hole after described mold core one end passes through through-hole and circle module centers；The round module end face center
Protrusion is set, recessed portion is arranged in bottom center, and the recessed portion of two neighboring round module offsets with protrusion, and recessed portion and
The full skirt die cavity of outdoor terminal is formed between protrusion, is formed between the center cavity and mold core of several circle modules outdoor
The casing die cavity of terminal.
Further, the top surface of the round module lug is the first inclined surface tilted down, the round module recess
The top surface in portion is the second inclined surface tilted down, and the tilt angle of first inclined surface is slightly larger than the inclination of the second inclined surface
Angle forms the full skirt die cavity of outdoor terminal between the first inclined surface and the second inclined surface of the two neighboring round module.
Further, the joining place between the first inclined surface and the second inclined surface of the round module and circle module inner wall is equal
For arc.
Further, the lower die holder side wall also sets up sprue and material feeding slot, the material feeding slot connection sprue and set
Pipe die chamber.
Further, the outer diameter of the round module is consistent, and the outer wall of the round module also opens up several shrinkage pools.
Further, the mold core also sets up end socket close to one end of upper module.
Usefulness of the present invention:
First: this mold produces outdoor terminal using the circle module of several annular shapes, has overturned traditional upper and lower or left and right and has closed
The frame mode of mould, therefore longitudinal molding seam will not be generated；
Second: piecing together the shape of full skirt also with the circle module of several annular shapes, form molding seam in the umbrella tip of full skirt；
Third: making full use of the gradient that full skirt is downward, and when moulding by casting by the way of handstand, the umbrella tip of full skirt becomes arranging
Gas channel, therefore can't see molding seam on product, and demoulding is convenient；
4th: shrinkage pool is arranged in circle module outer wall, convenient for rotation adjustment position when assembly mold.
Detailed description of the invention

A kind of outdoor terminal mold without longitudinal molding seam, mainly include upper die holder 1, lower die holder 2, mold core 3 and several
The circle module 4 being stacked between upper die holder 1 and lower die holder 2；1 center of upper die holder is arranged through-hole 1.1, in lower die holder 2
Hole 2.1 is supported in heart setting, and the round module 4 is annular shape, and described 3 one end of mold core is inserted into after passing through through-hole 1.1 and circle 4 center of module
To in hole 2.1；Protrusion 4.1 is arranged in 4 end face center of round module, and recessed portion 4.2, two neighboring round mould is arranged in bottom center
The recessed portion 4.2 of block 4 offsets with protrusion 4.1, and the full skirt of outdoor terminal is formed between recessed portion 4.2 and protrusion 4.1
Die cavity 5 forms the casing die cavity 6 of outdoor terminal between the center cavity and mold core 3 of several circle modules 4.
Further, the top surface of 4 protrusion 4.1 of round module is the first inclined surface 4.3 tilted down, the round mould
The top surface of 4 recessed portion 4.2 of block is the second inclined surface 4.4 tilted down, and the tilt angle of first inclined surface 4.3 is slightly larger than
The tilt angle of second inclined surface 4.4, between the first inclined surface 4.3 and the second inclined surface 4.4 of the two neighboring round module 4
Form the full skirt die cavity 5 of outdoor terminal.
Further, between the first inclined surface 4.3 and the second inclined surface 4.4 of the round module 4 and circle 4 inner wall of module
Joining place is arc.
Further, 2 side wall of lower die holder also sets up sprue 2.2 and material feeding slot 2.3, and the material feeding slot 2.3 is connected to
Sprue 2.2 and casing die cavity 6.
Further, the outer diameter of the round module 4 is consistent, and the outer wall of the round module 4 also opens up several shrinkage pools 4.5.
Further, the mold core 3 also sets up end socket 7 close to one end of upper module 1.
Existing mold (referring to Fig. 1) is two pieces of molds using same structure, upper module 8 and lower module 9, left and right split
Or be poured after upper and lower split, mosaic will form molding seam.
This mold working principle
Circle module 4 is stacked gradually and is arranged between upper die holder 1 and lower die holder 2, the insertion of mold core 3 simultaneously, casting fixed with end socket 7
When, mold is stood upside down, upper die holder 1 injects castable under, from sprue 2.2, pieces together full skirt between adjacent two pieces round modules 4
Shape, form molding seam in the umbrella tip of full skirt, but due to being casting of standing upside down, full skirt can be made full use of downward
Gradient, the umbrella tip of full skirt become exhaust passage, therefore can't see molding seam on product.
The outdoor terminal mould stitched is molded without longitudinal direction the invention is not limited to a kind of involved in above-mentioned specific embodiment,
Those skilled in the art can also make a variety of variations accordingly, but any be equal or similar variation is all answered with of the invention
Cover within the scope of the claims.
