Description
Technical field
The present invention relates to a kind of auto parts and components assembly tool, especially relate to a kind of encapsulated pre-pressing die of auto absorber piston.
Background technology
For extending the service life of auto absorber piston, it will usually wrap up one layer of film outside piston.The existing pre-pressing die for encapsulated of auto absorber piston, including for the prod cast of sheathed film be located at the pressing mold being wrapped in outside piston by film after pressure above prod cast, pressing mold is connected and composed by locating flange, elastic shrinkage set, elastic tightening space washer and correcting packing ring.This pre-pressing die can be used for semi-automatic semi-hand and produces, it is possible to carry out full-automatic production with other mechanical engagement.But this pre-pressing die is in use, there is deviation owing to piston and prod cast position, under pressing mold during moulding sheet parcel piston, piston and prod cast can be moved, and cause encapsulation inconsistent, cause percent defective higher.
Summary of the invention
The technical problem to be solved is to provide a kind of encapsulated pre-pressing die of encapsulated stay-in-grade auto absorber piston.
The present invention solves the technical scheme that above-mentioned technical problem used: a kind of encapsulated pre-pressing die of auto absorber piston, and it includes that film is wrapped up the pressing mold of piston by the prod cast and being located at for sheathed film after pressure above prod cast；It is coaxially arranged with, at described prod cast bottom centre, the locating dowel passing piston center hole；It also includes the locating piece for laying piston, and described locating piece is provided with the hole, location matched with locating dowel.
Compared with prior art, it is an advantage of the current invention that the locating piece being additionally arranged for laying piston, and arrange on locating piece and to be coaxially arranged with and pass the hole, location that the locating dowel of piston center hole matches at prod cast bottom centre, after piston arrives on locating piece, when putting down prod cast, locating dowel matches with the hole, location on locating piece after piston center hole, makes piston consistent with prod cast location, so that it is guaranteed that encapsulated steady quality.
As preferably, the bottom of described locating dowel is up big and down small frustum, and hole, described location is frustum hole.Frustum progressively inserts frustum hole, has guide effect, inserts more convenient.
As improvement, described pressing mold includes positioning mould, being located at the mould heart positioned in the mould mould chambers of the heart and for the locating flange being locked in the mould chambers of the heart by the mould heart.Only needing more the die change heart and prod cast to may be used for different types of piston rubber-coating to produce, the suitability is big.
As preferably, the described mould heart is fabricated from iron.
As preferably, between described location mould and the mould heart and between the described mould heart and locating flange, it is provided with pad.
As preferably, fix with the push rod of a push actuator bottom described locating piece and be connected.
As preferably, described prod cast top is provided with the annular groove for facilitating manipulator clamping to promote.Manipulator clamping is facilitated to promote, it is achieved full-automatic production.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
Embodiment 1 is illustrated in figure 1 a kind of encapsulated pre-pressing die of auto absorber piston, and it includes that film is wrapped up the pressing mold of piston by the prod cast 1 and being located at for sheathed film after pressure above prod cast 1；Being coaxially arranged with the locating dowel 11 passing piston center hole at prod cast 1 bottom centre, prod cast 1 top is provided with the annular groove 12 for facilitating manipulator clamping to promote；It also includes the locating piece 2 for laying piston, and locating piece 2 is provided with the hole, location 21 matched with locating dowel 11.Wherein, the bottom of locating dowel 11 is up big and down small frustum, hole 21, location is the frustum hole mated with frustum, during below prod cast 1, due to coordinating between frustum with frustum hole, prod cast 1 drives piston to be adjusted to accurate location, it is to avoid pressing mold and prod cast 1 and the collision of piston, pressing mold is hardly damaged with prod cast 1, and service life is long.
In the present embodiment, pressing mold is formed by positioning mould 3, the mould heart 4 being located in the mould 3 mould chambers of the heart of location and the locating flange 5 for being locked in the mould chambers of the heart by the mould heart 4.Instead of original pressing mold connected and composed by locating flange, elastic shrinkage set, elastic tightening space washer and correcting packing ring, more reasonable structure, may continue to use according to the different size of piston suitable mould heart 4 of replacement and prod cast 1.It addition, be provided with pad 6 between location mould 3 and the mould heart 4 and between the mould heart 4 and locating flange 5, one is in pressing mold work process, prevents the mould heart 4 and location mould 3 and locating flange 5 direct collision；Two is after the more die change heart 4, the mould heart 4 can be made to match with location mould 3 by exchanging the pad 6 of different-thickness.
As preferably, the mould heart 4 is made up of the hard metal such as ferrum or rustless steel or hard metal alloys, will not produce substantially deformation because of temperature Change, and encapsulated quality is good, and service life is long.
Embodiment 2 as in figure 2 it is shown, with the auto absorber piston of embodiment 1 encapsulated pre-pressing die essentially identical, including prod cast 1, locating piece 2 and the pressing mold being made up of location mould 3, the mould heart 4 and locating flange 5；Difference is, fixes with the push rod top of push actuator 7 and be connected bottom locating piece 2, and push actuator 7 can couple with PLC control system.Wherein, push actuator 7 can use motor, cylinder or oil cylinder.Promote encapsulated speed, improve work efficiency.
