Abstract
The invention discloses a self-centering die for producing BVVB-S and RVB products. The self-centering die comprises a die core and a die sleeve, wherein the die core comprises a connecting flange; the front end of the connecting flange is a cone head; the rear end of the connecting flange is a thread head; a main runner is arranged in the die core; two rear extrusion pipe assembling holes are formed in the front end of the main runner; the die sleeve comprises a flange; a conical cavity is formed in the die sleeve; two front extrusion pipe assembling holes are formed in the front end of the conical cavity and corresponding to the two rear extrusion pipe assembling holes; the two front extrusion pipe assembling holes are communicated; the connecting flange on the die core and the flange on the die sleeve are connected by a plurality of locating pins which are uniformly distributed in the circumferential direction; extrusion pipes are arranged in the front extrusion pipe assembling holes and the front extrusion pipe assembling holes correspondingly; an annular sheath extrusion runner is formed between the external surface of the cone head of the die core and the internal surface of the conical cavity; the annular sheath extrusion runner is communicated with the two front extrusion pipe assembling holes.
Description
Technical field
The present invention relates to cable extrusion mould technical field, particularly a kind of self-centering mould of producing BVVB-S, RVB wire products.
Background technology
At present, electric wire manufacture processing oversheath is extruded operation and is generally adopted extrusion molding machine head to carry out extrusion moulding processing, its structure and process principle are: crosshead body, be with heating system outward, protection and the position of fixedly extruding directed movement, make plastics in Continuous Extrusion Process, keep plasticizing to shift with directed, plastics are clamp-oned by extruding machine the runner that movement joins with it from the runner mouth of funnel, runner is designed to the groove that round and smooth bending turns to, plastics are transformed into horizontal direction along direction and the vertical direction of runner, plastics are shunted by movement middle part simultaneously in running, because movement is a cylinder, so the position of plastic cup eccentric disk and moulding outer die casing and head interface forms an annular plastics stream.Stream of plastic enters into moulding adventitia along the cylindrical space between core rod and outer die casing, by the shape of collar extension and follow-up cooling device, plastic shape-forming is extruded and is being had core rod control core position outer surface.In the time that core rod and outer die casing, adventitia have skew, need by tuningout screw, give to adjust fixation from upper and lower, orientation, four of left and right and be in together an axle center with the center of movement, reach uninfluenced object, thus formation electric wire extrusion molding process.But such extrusion molding machine head is in the time producing BVVB-S, RVB wire products, there are the following problems: insulated wire cores waste is large, mode transfer difficulty and time-consuming.
Summary of the invention
Technical problem to be solved by this invention is to provide for the existing deficiency of prior art the self-centering mould of a kind of BVVB-S of production, RVB wire products.
Technical problem to be solved by this invention can be achieved through the following technical solutions:
A kind of self-centering mould of producing BVVB-S, RVB wire products, comprise core rod and die sleeve, described core rod has an adpting flange, the front end of adpting flange is conehead, the rear end of adpting flange is thread head, in core rod, be provided with sprue, be provided with two extruding pipe assembling metapores at the front end of described sprue; Described die sleeve has a flange, has cone chamber in die sleeve, and the front end in cone chamber is provided with two positions and assembles with two extruding pipes the extruding pipe that metapore is corresponding and assemble front hole, and two extruding pipes assemble front hole and are connected; Adpting flange on described core rod is connected by the circumferential uniform alignment pin in some edges with the flange on die sleeve; Assemble in front hole and dispose extruding pipe at corresponding extruding pipe assembling metapore and extruding pipe; Between the inner surface in the conehead outer surface of described core rod and described cone chamber, form a ring jacket extrusion channel, described ring jacket extrusion channel assembles front hole with described two extruding pipes and is communicated with.
Owing to having adopted technical scheme as above, self-centering mould of the present invention carries out tuningout without tuningout screw, has saved the mode transfer time, has reduced the waste of insulated wire cores.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, further describe the present invention below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, a kind of BVVB-S of production providing in figure, the self-centering mould of RVB wire products, comprise core rod 10 and die sleeve 20, core rod 10 has an adpting flange 11, the front end of adpting flange 11 is conehead, the rear end of adpting flange 11 is thread head, in core rod 10, is provided with sprue, is provided with two extruding pipe assembling metapores at the front end of sprue; Die sleeve 20 has a flange 21, has cone chamber in die sleeve 20, and the front end in cone chamber is provided with two positions and assembles with two extruding pipes the extruding pipe that metapore is corresponding and assemble front hole, and two extruding pipes assemble front hole and are connected; Adpting flange 11 on core rod 10 is connected by the circumferential uniform alignment pin 30 in some edges with the flange 21 on die sleeve 20; Assemble and in front hole, dispose extruding pipe 40 at corresponding extruding pipe assembling metapore and extruding pipe; Between the inner surface in the conehead outer surface of core rod 10 and cone chamber, form a ring jacket extrusion channel 50, ring jacket extrusion channel 50 assembles front hole with two extruding pipes and is communicated with.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
