Abstract
The utility model discloses a saving type resin extrusion molding mechanism. The saving type resin extrusion molding mechanism comprises a hollow cylinder, a central guide tube, a cylindrical piston and a hollow machine head, wherein the central guide tube is axially positioned on the center position of the cylinder; the cylindrical piston is sleeved outside the central guide tube; the machine head comprises a tapered body and a cylindrical neck mould, wherein the bottom end of the body taper is connected with one end of the cylinder in a sealing manner; the head end of the body taper is integrally formed with the neck mould; an extrusion molding guide wire axially penetrates through the central guide tube, the body and the neck mould; a cushion block is arranged on the end surface, towards one end of the machine head, of the piston; the piston is capable of axially sliding along the central guide tube, and stops at the intersection of the body and the cylinder, so that the cushion block extends to the machine head. The saving type resin extrusion molding mechanism is simple in structure, convenient to implement, capable of effectively improving the extrusion molding process of the resin, capable of saving the cost and capable of improving the yield.
Description
Technical field
The utility model relates to a kind of extruder moulding section mechanism, specifically relates to a kind of economizing type resin extrusion molding mechanism, is applicable to the resin extrusion molding cost savings and improves production capacity.
Background technology
The moulding section that is used for the extruder of resin extrusion molding partly is made up of circle cylinder, piston, center conduit and head etc. usually.Wherein, circle cylinder one end docks with head one end, and center conduit is provided with round cylinder axial centre place, and piston bush is located on the center conduit, can be along the center conduit extrusion resin that endwisely slips; By piston motion extrusion resin, make resin extruded back attached to by finally obtaining having the electric wire of insulation characterisitic on the plain conductor in the center conduit.Consider that for function circle cylinder and piston are usually designed to cylindricality, head is designed to taper according to the extrusion needs, because head is taper, the extreme position of piston-advance rests on the interface place of round cylinder and head usually, as depicted in figs. 1 and 2.Therefore, when extrusion molding finished, the head tapering part was through the residual a certain amount of resin of regular meeting, thereby caused resin discarded, caused wastage of material, and production capacity reduces, and production cost increases.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model proposes a kind of economizing type resin extrusion molding mechanism, simple in structure, be convenient to implement, can effectively improve resin extrusion molding technology, save cost, improve production capacity.
The technical solution of the utility model is achieved in that
A kind of economizing type resin extrusion molding mechanism comprises that hollow columnar circle cylinder, axial location be located at the center conduit of the center position of described round cylinder, be sheathed on described center conduit outer plunger piston and hollow head; Described head comprises taper body and column mouth mould, and described body awl bottom and described round cylinder one end are tightly connected, described body conehead end and described mouthful of mould integrated molding; The extrusion molding traverse shaft is to passing described center conduit, described body and described mouthful of mould, described piston is provided with cushion block towards the end face of described head one end, described piston can endwisely slip along described center conduit, and be stopped at the intersection of described body and described round cylinder, described cushion block is extend in the described head.
As a further improvement on the present invention, described cushion block is fixed in described piston on the end face of described head one end by screw.
As a further improvement on the present invention, it is round table-like that be shaped as and the described head taper of described cushion block matches, and described cushion block axially is sheathed on the described center conduit, and the central axes of the central axis of described cushion block and described head.
The beneficial effects of the utility model are: the utility model provides a kind of economizing type resin extrusion molding mechanism, by shape and the die shape cushion block that matches is set on the end face of head one side at piston, when piston reaches maximum extrusion position, utilize cushion block to continue to stretch into head, to reach with the resin purpose utilized of extrusion to greatest extent, solve the resin material waste that causes owing to remaining resin in the traditional handicraft head, saved resin, improved production capacity.

The specific embodiment
As shown in Figure 3 and Figure 4, a kind of economizing type resin extrusion molding mechanism comprises that hollow columnar circle cylinder 1, axial location be located at the center conduit 2 of the center position of described round cylinder 1, be sheathed on described center conduit 2 outer plunger piston 3 and hollow head 4; Described head 4 comprises taper body 41 and column mouth mould 42, and described body 41 awl bottoms and described round cylinder 1 one ends are tightly connected, described body 41 conehead ends and described mouthful of mould 42 integrated moldings; Extrusion molding lead 7 axially passes described center conduit 2, described body 41 and described mouthful of mould 42, described piston 3 is provided with cushion block 5 towards the end face of described head 4 one ends, described piston 3 can endwisely slip along described center conduit 2, and be stopped at the intersection 6 of described body 41 and described round cylinder 1, described cushion block 5 is extend in the described head 4.Like this, compare conventional resins extrusion molding mechanism, the utility model is by being provided with cushion block at piston towards the end face of head one end, this cushion block slides and stretches in the taper head, piston can be remained in resin extruded in the head conical body after the release of center conduit slip extrusion resin, thereby reach the purpose that improves production capacity and save resin.
Preferably, described cushion block 5 is fixed in described piston 3 on the end face of described head 4 one ends by screw.Like this, in the time of can avoiding returning behind the piston extrusion resin, cushion block breaks away from center conduit; And cushion block is connected with piston by screw, after the long-time use of cushion block has distortion, can recover original function by simple substitution.
Preferably, it is round table-like that be shaped as and described head 4 tapers of described cushion block 5 match, and described cushion block 5 axially is sheathed on the described center conduit 2, and the central axes of the central axis of described cushion block 5 and described head 4.Like this, the resin that piston remains in the head conical body after the release of center conduit slip extrusion resin can be extruded to greatest extent, thus the purpose that reaches further raising production capacity and save resin.
Preferably, the material of described cushion block 5 is nonmetallic materials, and its hardness is far below the hardness of head material.During actual the use, can avoid because of cushion block material scratch head really up to the mark and unexpected.
After preferred embodiment of the present utility model was implemented, the resin extruded production capacity of the present invention had improved 3.45%, and resin is discarded to have reduced 51%.
Above embodiment is with reference to accompanying drawing, and preferred embodiment of the present utility model is elaborated.Those skilled in the art is by carrying out modification or the change on the various forms to the foregoing description, but do not deviate under the situation of essence of the present utility model, all drops within the protection domain of the present utility model.
