Abstract
The present invention relates to a kind of corrugated rubber mould, including internal model and external mold, the external mold includes upper mould symmetrical above and below and lower mould；The internal model is the cylinder being spliced into by four pieces, a plug is provided with the internal model, the inner surface formed that closed by the upper mould and lower die button that the internal model is positioned over the external mold is in undulatory external mold die cavity, the internal model realizes radial direction and axially position by block and locating piece respectively, and is locked by being located at the clamp nut on the outside of the locating piece.Bellows rubber pattern of the present invention, there is the characteristics of simple in construction, manufacturing cost is low, and convenient operation is implemented.
Description
Technical field
The invention belongs to technical field of mold, and in particular to a kind of corrugated rubber mould.
Background technology
Dust cover on hydraulic cylinder, there is corrugated outer surface, it is desirable to there are preferable intensity, oil resistant and ageing resistace,
Because the shape of endoporus is special, internal model core pulling has certain difficulty.The surfaces externally and internally of workpiece requires that smooth, uniform wall thickness, glue are filled out
Uniformly, pore-free, cold shut, do not adhere to die surface.Curing temperature control at 140~150 DEG C, vulcanizate Shore hardness 70~
75, tearing toughness is more than 3.5MPa, must not have over cure, owe sulphur, lacks material, tear phenomenon generation.
The content of the invention
A kind of convenience of the dust cover on hydraulic cylinder is provided it is an object of the invention to solve above-mentioned technical problem
The bellows rubber pattern used.
To achieve the above object, the present invention uses following technical scheme：
A kind of corrugated rubber mould, including internal model and external mold, the external mold include upper mould symmetrical above and below and lower mould；Institute
It is the cylinder being spliced into by four pieces to state internal model, and a plug is provided with the internal model, and the internal model is positioned over described outer
The inner surface formed that closed by the upper mould and lower die button of mould is that the internal model passes through block respectively in undulatory external mold die cavity
And locating piece realizes radial direction and axially position, and locked by being located at the clamp nut on the outside of the locating piece.
Preferably, it is machined with clout groove on the lower mould.
Preferably, the upper mould and upper mould are provided with handle.
Bellows rubber pattern of the present invention, there is the characteristics of simple in construction, manufacturing cost is low, and convenient operation is implemented.
Brief description of the drawings
Fig. 1 show a kind of structural representation of corrugated rubber mould provided in an embodiment of the present invention；
Fig. 2 show a kind of structural representation of the internal model of corrugated rubber mould provided in an embodiment of the present invention；
In figure：1. the block of 7. handle of nut 2. locating piece, 3. external mold, 4. workpiece, 5. internal model, 6. plug 8..
Embodiment
Below, the substantive distinguishing features and advantage of the present invention are further described with reference to example, but not office of the invention
It is limited to listed embodiment.
Referring to Fig. 1, this, which illustrates the embodiment of the present invention, provides a kind of structure of corrugated rubber mould, for convenience of description,
It illustrate only the part relevant with the embodiment of the present invention.
Fig. 1~2, a kind of corrugated rubber mould, including internal model 5 and external mold 3 are referred to, the external mold includes symmetrical above and below
Upper mould and lower mould；The internal model 5 is the cylinder that is spliced into by four internal model pieces 51,52,53,54, in the internal model 5
Provided with a plug 6, the inner surface formed that closed by the upper mould and lower die button that the internal model 5 is positioned over the external mold is corrugated
External mold die cavity in, match with the appearance and size of the workpiece 4 of shaping, the internal model passes through block 8 respectively and locating piece 2 is real
Now described external mold die cavity central diameter to and axially position, and the clamp nut 1 by being located at the outside of locating piece 2 locks.
Preferably, clout groove is machined with the lower mould, clout groove is processed on lower mould, to accommodate in process
Clout.
Preferably, the upper mould and upper mould are provided with handle 7.
Internal model of the present invention is made up of piece, block, locating piece, plug and nut, is easy to core pulling.
During assembling, first by after internal model piece split, by the endoporus and the major diameter fit at the both ends of plug 6 at both ends, internal model is spelled
The both ends external diameter of block is locked on plug 6 respectively with the external diameter of block 8 and locating piece 2 with 15 ° of taper fit by nut 1,
Composition one.
The gap between internal model piece after combination is less than 0.01mm, to ensure the smooth of workpiece lumen and prevent overlap
Produce.
Interior membrane module is accurately positioned by block 8 and locating piece 2 in outer model cavity, external diameter and the external mold endoporus of block 8
Coordinate, thereby may be ensured that the gap between internal model and external mold, radial positioning is accurate.Locating piece is by with frustum shoulder and cavity plate
Cavity plate groove is accurately positioned, so as to ensure axial direction
Preferably, 21 bottoms of the bottom plate are provided with multiple installation locating pieces 28, and the installation locating piece 28 can basis
It is actually needed and corresponding quantity is set, can is one, can also be two, or three.
The shaping mould of the U-shaped part of the present invention, by being used on forcing press, can by the punch member downwards with
Described cavity plate unit matching, the plate to be formed being positioned on the flexible die is pressed into the die cavity and forms phase
The U-shaped shape answered, and effect is good.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
