Abstract

The utility model discloses a high-precision positioning structure of an oil cylinder pulling core. The high-precision positioning structure comprises a panel, a stripper plate, a mould base, an oil cylinder, a connecting rod and a slide base, wherein the panel, the stripper plate and the mould base are connected in sequence; the oil cylinder is fixed on the mould base and connected with the slide base by the connecting rod; a T slot is arranged on the inclined plane of the slide base; a slide slot corresponding to the T slot is arranged on one surface of the slide block; the slide block can move along the T slot; the high-precision positioning structure further comprises a positioning hole and a positioning block, wherein the positioning hole penetrates through the panel, the stripper plate, the mould base and the slide base; one end of the positioning block is fixed on the panel; the other end of the positioning block penetrates through the stripper plate, the mould base and the slide base, and protrudes out of the slide base; and a bulge is arranged on a position, protruding out of the slide base, of the positioning block. According to the utility model, the positioning block is additionally arranged in the middle of the slide block, so that oil pressure system driving of a former is reduced, precision and service live of a high-precision mould are ensured, product quality is also guaranteed, and use cost of the mould is reduced.

Description

A kind of high-precision fixed bit architecture of loose core of oil cylinder

Technical field

The utility model relates to the loose core of oil cylinder device of injection machine, more specifically, relates to a kind of high-precision fixed bit architecture of loose core of oil cylinder.

Background technology

Common large stroke injection mold need to pass through oil cylinder pushing slide block movement in the time of injection moulding, and be fixed in fixed position, original slide block is fixedly that oil hydraulic system by forming machine drives oil cylinder to fix in the time producing, because of the oil hydraulic system of forming machine unstable, make slide block in the time producing often occur retreating, cause product quality unstable, even also affect the service life of mould, therefore, need the high-precision fixed bit architecture of a kind of loose core of oil cylinder of exploitation badly, to realize the accurate location of slide block, ensure the stability of production process.

Summary of the invention

For addressing the above problem, the utility model provides a kind of high-precision fixed bit architecture of loose core of oil cylinder, and this structure can increase the service life of slide block, reduces the use cost of mould.

For achieving the above object, the technical solution of the utility model is:

A kind of high-precision fixed bit architecture of loose core of oil cylinder, comprise panel, water gap plate, die holder, oil cylinder, connecting rod, slide, locating piece, slide block, described panel, water gap plate, die holder connects successively, described oil cylinder is fixed on die holder, and be connected with slide by connecting rod, on the inclined-plane of described slide, be provided with T groove, on a face of described slide block, be provided with the chute corresponding with T groove, described slide block can move along T groove, described panel, water gap plate, die holder, slide is provided with square locating hole, the square locating hole of described slide is that inside has inclined-plane, the class bellmouth that import large outlet is little, it is upper that described locating piece one end is screwed in panel, the other end runs through water gap plate, die holder, slide also protrudes from outside slide, the position of the described outstanding slide of locating piece is provided with projection.

Beneficial effect: the utility model is by increase locating piece in the middle of slide block, thereby the oil hydraulic system of minimizing forming machine drives, and ensures precision and the service life of high-accuracy mould, also makes the quality of product be guaranteed, and has reduced the use cost of mould.

Detailed description of the invention

As Fig. 1, 2, 3, 4, shown in 5, a kind of high-precision fixed bit architecture of loose core of oil cylinder, comprises panel 1, water gap plate 2, die holder 3, oil cylinder 4, connecting rod 5, slide 6, locating piece 7, slide block 8, described panel 1, water gap plate 2, die holder 3 connects successively, described oil cylinder 4 is fixed on die holder 3, and be connected with one end of slide 6 by connecting rod 5, described slide 6 other ends are provided with inclined-plane, on described inclined-plane, be provided with T groove 9, on a face of described slide block, be provided with the chute corresponding with T groove 9 10, the sliding grain 10 of slide block 8 also can be moved along T groove 9 along T grain 9 matched moulds, described panel 1, water gap plate 2, die holder 3, slide 6 is provided with square locating hole 11, and the square locating hole 11 of described slide has inclined-plane for inside, the class bellmouth that import large outlet is little, described locating piece 7 one end are fixed on panel 1, and the other end runs through water gap plate 2, die holder 3, outside slide 6 outstanding slide 6, the described outstanding position of locating piece 7 is provided with projection, can be in front, when rear mold matched moulds, be stuck in groove corresponding to rear mold, thereby and slide block 8 is fixed on to corresponding position, and because locating piece 7 is equipped with corresponding inclined-plane with slide 6, can play the effect of hi-Fix, prevent that mould from occurring because the immense pressure of injection moulding causes slide block the potential safety hazard of bringing aborning because the oil hydraulic system of forming machine is unstable, this just makes slide block and die life be guaranteed, and has also stablized the quality of product.
