A kind of sleeve injection mold, it is characterised in that: include solid plate, middle template, moving platen, the first support plate, baffle plate, dynamic model backing plate, the second support plate, dynamic model backing plate successively；Arranging middle model core in middle template, in moving platen, opposite position arranges dynamic mould core, arranges air-leg between middle model core and dynamic mould core, arranges movable model set outside dynamic mould core, forms die cavity between dynamic mould core and dynamic model jacket；In first support plate, opposite position is threaded die cavity；One end of tooth bar is connected with middle template, and wheel and rack is meshed, and gear and bevel gear concentric are arranged on gear shaft, and duplicate gear one end is connected with bevel gear, and the other end is connected with screw thread die cavity, thus driving screw thread die cavity to rotate the demoulding。
Preferably, described sleeve injection mold, it is characterised in that: described solid plate, middle template, moving platen, the first support plate and the second support plate corner opposite position are provided with the guide pillars and bushes for positioning and lead。
Preferably, described sleeve injection mold, it is characterised in that: also including mould foot, described mould foot is arranged on outside dynamic model backing plate。
Preferably, described sleeve injection mold, it is characterised in that: also include joint, be connected between described joint and dynamic mould core。
Preferably, described sleeve injection mold, it is characterized in that: described dynamic model jacket outer surface is provided with multiple cone, described middle template, moving platen and the first support plate are provided with the taper hole matched with cone, by blind-mate between cone and taper hole, in order to realize being accurately positioned between die cavity, middle template, the first support plate。
Preferably, described sleeve injection mold, it is characterised in that: described injection mold is mould four chamber。
Beneficial effect: sleeve injection mold provided by the invention, adopts unique rack pinion linkage demoulding, in order to prevent generation vacuum between sleeve and dynamic mould core, passes into compression air from joint, and sleeve is in the effect bottom knockout of air-leg。Blind-mate between taper hole, cone, in order to realize being accurately positioned between die cavity, middle template, the first support plate, it is prevented that the even phenomenon of wall unevenness occurs because of dislocation in sleeve, it is ensured that the molding of moulding and the quality of product。
Accompanying drawing explanation
Fig. 1 is the top view of injection mold of the present invention；
Fig. 2 is Section A-A figure in Fig. 1；
In figure: solid plate 1, middle template 2, die cavity 3, middle model core 4, air-leg 5, dynamic mould core 6, screw thread die cavity 7, moving platen the 8, first support plate 9, baffle plate 10, gear 11, bevel gear 12, tooth bar 13, duplicate gear the 14, second support plate 15, dynamic model backing plate 16, joint 17, mould foot 18, taper hole 19, cone 20。
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further described。
As depicted in figs. 1 and 2, a kind of sleeve injection mold, including solid plate 1, middle template 2, die cavity 3, middle model core 4, air-leg 5, dynamic mould core 6, screw thread die cavity 7, moving platen the 8, first support plate 9, baffle plate 10, gear 11, bevel gear 12, tooth bar 13, duplicate gear the 14, second support plate 15, dynamic model backing plate 16, joint 17, mould foot 18, taper hole 19, cone 20；
Arranging middle model core 4 in middle template 2, in moving platen 8, opposite position arranges dynamic mould core 6, arranges air-leg 5 between middle model core 4 and dynamic mould core 6, arranges movable model set outside dynamic mould core 6, forms die cavity 3 between dynamic mould core 6 and dynamic model jacket；In first support plate 9, opposite position is threaded die cavity 7；One end of tooth bar 13 is connected with middle template 2, and gear 11 is meshed with tooth bar 13, and gear 11 and bevel gear 12 concentric are arranged on gear shaft, and duplicate gear 14 one end is connected with bevel gear 12, and the other end is connected with screw thread die cavity 7, thus driving screw thread die cavity 7 to rotate。
Described solid plate 1, middle template 2, moving platen the 8, first support plate 9 and 15 4 jiaos of opposite positions of the second support plate are provided with the guide pillars and bushes for positioning and lead。
Also including mould foot 18, described mould foot is arranged on outside dynamic model backing plate 16。
Preferably, described sleeve injection mold, it is characterised in that: also include joint 17, be connected between described joint 17 and dynamic mould core 6。
Preferably, described dynamic model jacket outer surface is provided with multiple cone 20, described middle template 2, moving platen 8 and the first support plate 9 are provided with the taper hole 19 matched with cone 20, by the blind-mate between cone 20 and taper hole 19, in order to realize being accurately positioned between die cavity 3, middle template the 2, first support plate 9。
In the present embodiment, producing to realize rapid batch, described injection mold is mould four chamber。
Sleeve body and injection mould analysis: material: polyethylene, shrinkage factor 1.5-2.6%, wall thickness 1mm。This moulding can not have dislocation and deform, and also has appearance requirement simultaneously, namely requires that gate vestiges is only small, it is impossible to the vestige of moulding typing and the demoulding occur。If there being the existence of moulding typing vestige, also affect the cooperation of M50*1.5 thread size。
The work process of the present invention is as follows: when die joint II-II is opened, middle template 2 band carry-over bar 13 moves, gear 11 on gear shaft and bevel gear 12 are rotated, then drives duplicate gear 14 and screw thread die cavity 7 to rotate, so that the M50*1.5 screw thread demoulding on sleeve。In order to prevent generation vacuum between sleeve and dynamic mould core 6, passing into compression air from joint 17, sleeve is in the effect bottom knockout of air-leg 5。Blind-mate between taper hole 19, cone 20, in order to realize being accurately positioned between die cavity 3, middle template the 2, first support plate 9, it is prevented that the even phenomenon of wall unevenness occurs because of dislocation in sleeve。
The above is only the preferred embodiment of the present invention; it is noted that, for those skilled in the art; under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention。
