Description
Technical field
The utility model is related to a kind of nonmetallic shaping dies, more particularly to a kind of recombinant material forming mode locking prevents swollen one-step method
U-shaped mold, specifically a kind of recombinant material shapes U-shaped mold.
Background technology
Using the fast-growing woods, mangosteen woods and woody low value shrub as raw material, and then extends and utilize agricultural " three surplus objects " and work
Industry waste, by the technological means such as modification, recombination, compound, integrated, manufacture specification is adjustable, function is optional, environmentally protective follows
The recombinant material that ring utilizes, the pressurize of special U-shaped mold, typically two-step method：The first step, the locked mode pin in the interpolation of mode locking hole,
It pushes down cover board and realizes pressurize；Second step is put into threaded anti-expansion pin in preventing swollen notch, and tightens screw by hand, prevents side
To swollen type.Therefore, on the side plate of existing mold, existing mode locking hole, and have anti-swollen notch, side plate intensity is significantly affected.
Existing mode locking hole is more than locked mode pin, and the two is that the inscribe of big roundlet coordinates.In two step interludes, tangent line connects
It touches and is not enough to overcome lateral expanding force, so in the action gap of two steps, huge lateral expanding force overcomes the resistance of the friction at tangent line
Mold is expanded into splayed configuration, when implementing second step, has been the mold being deformed, can only prevent the lateral expansion later stage by power
Residual deformation.
With the extension of mold usage time, mold gradually from flexible deformation, fatigue, turns to plastic deformation, cracking direction
Become, accumulative deflection is also increasing.Therefore, two-step method has congenital lack in terms of die life, cost and product quality
It falls into.
Invention content
To solve the above problems, the utility model proposes a kind of recombinant materials to shape U-shaped mold, design is simple, easy to use,
Deformation resistant, it is antifatigue, prolong the service life.
The technical solution of the utility model：
A kind of recombinant material shapes U-shaped mold, it includes side plate, bottom plate, cover board, mode locking hole and locked mode pin, on bottom plate both sides
End is respectively provided with side plate and is formed U-shaped, and the upper end both sides of side plate are respectively designed with the mode locking hole of several mode locking holes and both sides one by one
Corresponding, several locked mode pins are respectively inserted in one-to-one mode locking hole, and cover board is between side plate and below locked mode pin.
Upper half disc is annular knurl face on the inside of the mode locking hole, and semi circular surface is smooth surface, mode locking hole upper half in the lower end of mode locking hole
Radius of circle is identical as locked mode pin radius, and mode locking hole lower half radius of circle is more than locked mode pin radius.
The locked mode pin both ends are respectively designed with circumference annular knurl face at the mode locking hole cooperation of U-shaped die side plate upper end,
Locked mode pin both ends of the surface are respectively designed with annular cutting edge, and the external cylindrical surface of annular cutting edge and locked mode pin is designed with chamfering.
The side plate forms U-shaped or by shape after monoblock steel plate bending with bottom plate integrally casting shaping or by welding method
At U-shaped.
The utility model has the advantages that design is simple, easy to use, deformation resistant is antifatigue, prolongs the service life；Locked mode pin
For the design of circumference annular knurl, end face annular cutting edge, locked mode pin under the action of interior expansive force, is rubbed with mold by the ditch dug with a plow in annular knurl face
It wipes, generates bank and close shearing resistance effect, do not generate lateral dislocation, effectively prevent the lateral bulging of mold.Therefore, the utility model eliminates
The anti-expansion pin notch of traditional moulds, mould strength higher, transmission are more convenient；The traditional anti-expansion pin apparatus for placing of synchronous cancellation, it is whole
Body structure simplifies, and flow more saves shorter.

Specific implementation mode
With reference to attached drawing 1-4, a kind of U-shaped mold of recombinant material forming, it includes side plate 1, bottom plate 2, cover board 3, mode locking hole 4 and lock
Mould pin 5,2 both sides upper end of bottom plate are respectively provided with side plate 1 and are formed U-shaped, and the upper end both sides of side plate 1 are respectively designed with several mode locking holes
4 and the mode locking holes 4 of both sides correspond, several locked mode pins 5 are respectively inserted in one-to-one mode locking hole 4, and cover board 3 is located at side
Between plate 1 and below locked mode pin 5.
The 4 inside upper half disc of mode locking hole is annular knurl face, and 4 inside lower half disc of mode locking hole is smooth surface, on mode locking hole 4
Semicircle radius is identical as 5 radius of locked mode pin, and the lower half radius of circle in mode locking hole 4 is more than the radius of locked mode pin 5.
5 both ends of locked mode pin are respectively designed with circumference annular knurl at 4 cooperation of mode locking hole of 1 upper end of U-shaped die side plate
