Abstract

The utility model relates to an obliquely-ejecting universal head with adjustable height. The universal head includes a universal head body, a stepped hole is formed at the middle of the universal head body, an obliquely-ejecting rod with a first screw hole extends to a large hole of the stepped hole and meanwhile a bolt extends from a small hole of the stepped hole and is in threaded connection with a first screw hole. The utility model is characterized in that the small hole of the stepped hole serves a second screw hole, a screw sleeve sleeved on a bolt is in threaded connection with a second screw hole, and the upper end surface of the screw sleeve is propped against the lower end surface of the obliquely-ejecting rod. Since the screw sleeve is additionally arranged, the height of theobliquely-ejecting rod can be adjusted by rotating the screw sleeve under the condition that both the bolt and the obliquely-ejecting rod are under the loosening state, the clearance between the obliquely-ejecting head and the die can be adjusted, and finally flash on the edge of the product can be eliminated. Therefore, the obliquely-ejecting universal head can eliminate the flash under the condition of not unloading and removing the die, the technical requirements for operating staff is lowered, the manpower is reduced, the modification rate is evidently improved, and the production cost islowered.

Description

Height adjustable oblique top Universal-head

Technical field

The utility model relates to a kind of Universal-head, specifically refers to a kind of oblique top Universal-head that is applicable in the injection machine.

Background technology

In injection machine, for the product that injection moulding is finished ejects from mould, usually dispose the oblique top Universal-head, the oblique top Universal-head comprises the Universal-head main body, have a shoulder hole at the middle part of this Universal-head main body, the angle ejector rod that the lower surface has screw stretches in the macropore of this shoulder hole, and offset with the cascaded surface of shoulder hole, be threaded mutually with the screw of this angle ejector rod after bolt stretches into from the aperture of shoulder hole simultaneously, make angle ejector rod and Universal-head main body be tightened to one, and the upper end of angle ejector rod is connected with the oblique top head that matches with product and male model plate.During use, the Universal-head main body is installed in the slide plate axis hole of mould by the cylindrical shaft of its both sides.Promote slide plate and angle ejector rod is moved upward through external force, product ejects mould the most at last.

In above-mentioned production process, because wearing out, wear and tear and extruding of mould tends to make the precise decreasing of mould, so that bigger gap appears between male model plate and oblique top head, and then overlap appears in the product edge after injection moulding.In order to eliminate above-mentioned phenomenon, mould can only be removed from injection machine at present, by the maintenance mould, make it to solve with the nose heave way that newly matches of oblique top.Obviously, this correcting mode needs a pincers worker to finish with wasting time and energy, and revises inefficiency, and injection moulding is produced and also can be delayed because of the maintenance of long period.

The utility model content

Technical problem to be solved in the utility model is at above-mentioned prior art present situation, and a kind of dismounting mould that need not is provided, and can adjust the oblique top Universal-head in gap between mould and the oblique top head apace.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this height adjustable oblique top Universal-head, include the Universal-head main body, have a shoulder hole at the middle part of this Universal-head main body, the angle ejector rod that the lower surface has first screw stretches in the macropore of this shoulder hole, be threaded mutually with first screw of this angle ejector rod after a bolt stretches into from the aperture of this shoulder hole simultaneously, it is characterized in that: the aperture of described shoulder hole is second screw, being threaded in this second screw is set in swivel nut on the above-mentioned bolt, and the lower surface of the upper surface of this swivel nut and above-mentioned angle ejector rod is inconsistent.

As further improvement of the utility model, preferably be exposed to the Universal-head main body outside the bottom of described swivel nut, and the outer end periphery of this swivel nut is hexagonal structure, when rotary threaded sleeve, can adopt conventional die nut and interior Hexagonal jacket to realize like this.

Compared with prior art, because the utility model has been set up swivel nut, thereby be under the state that unclamps when bolt and angle ejector rod, rotary threaded sleeve can be adjusted the height of angle ejector rod, can regulate the gap between oblique top head and the mould thereupon, finally can eliminate the finning on the product edge, so can finishing fast, the utility model eliminates the overlap operation under the situation of not counterdie, not form removal, and reduced operating personnel's specification requirement, reduced manpower, and can improve correction efficient significantly, reduce production costs.

Description of drawings

Fig. 1 is installed in structural representation in the mould for the utility model embodiment;

Fig. 2 be among Fig. 1 A to oblique top Universal-head structural representation;

Fig. 3 is that the B-B of Fig. 2 is to profile.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figures 1 to 3, this oblique top Universal-head is installed in the male model, and this male model is made up of bottom plate 7, time ejector retainner plate 10, last ejector retainner plate 20, counterdie pin 8 and male model plate 9 etc.; The oblique top Universal-head includes Universal-head main body 1, has a shoulder hole 11 at the middle part of this Universal-head main body, and both sides have the cylindrical shaft 12 that can stretch in the slide plate axis hole, and slide plate is connected mutually with last ejector retainner plate 20 and following ejector retainner plate 10 again; The bottom of angle ejector rod 2 is stretched in the macropore of this shoulder hole 11, and the lower surface of this angle ejector rod 2 has first screw 21, and the oblique top that matches with product 40 and male model plate 9 after by the pilot hole on the guide pad 30 in the upper end of angle ejector rod 6 links to each other; Be threaded mutually with first screw 21 of this angle ejector rod 2 after a bolt 3 stretches into from the aperture of this shoulder hole 11 simultaneously; The aperture of above-mentioned shoulder hole 11 is a screw, i.e. second screw, and being threaded in this second screw is set in swivel nut 4 on the above-mentioned bolt, and the lower surface of the upper surface of this swivel nut 4 and angle ejector rod 2 is inconsistent.

For the ease of rotary threaded sleeve 4, the bottom of above-mentioned swivel nut 4 exposes to the Universal-head main body, and the outer end periphery of this swivel nut is hexagonal structure 41.During operation, can pass through die nut or box spanner just can rotary threaded sleeve.

In process of production, when overlap occurring on finding product, operating personnel need earlier with mould altogether, then unclamp the injection machine sign indicating number screw of male model, with the die sinking of injection machine apart from increasing; Rotating bolt 3 then, and the bolt 3 and the lower end of angle ejector rod 2 are separated; Subsequently,, the swivel nut height is changed, the height of angle ejector rod 2 is changed, adjusted the gap L between oblique top 6 and the male model plate 9 then, and then can eliminate the overlap of product 40 with the bottom of die nut or box spanner rotary threaded sleeve 4; After eliminating gap L, again bolt 3 is tightened in first screw 21 of angle ejector rod by spring washer 5, injection machine is adjusted to the matched moulds state, the sign indicating number screw of locking injection machine gets final product.
