Specific embodiment
In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, letter will be made to embodiment below
Single introduction.
Such as Fig. 1 ~ 2, a kind of mold that can efficiently mold, including upper mold portion 1, lower mold portion 2, side form portion 3, die opening mechanism 4,
The upper mold portion 1 and the cooperation of 2 face of lower mold portion, the side form portion 3 is installed on the both sides of upper mold portion 1 and lower mold portion 2, the upper mold
Among portion 1 there is accommodating cavity 10, there is pneumatic mechanism 5, a pair of of diaphragm 6 of 5 lower part of pneumatic mechanism connection in accommodating cavity 10；
The die opening mechanism 4 includes die sinking connecting rod 40, bullet block group 30, and the die sinking connecting rod 40 includes cross bar 401, montant 402, horizontal
401 inner end of bar has the warpage portion 411 that face diaphragm 6 raises up, and the upper mold portion 1 is in the rear surface of 10 both sides of accommodating cavity
With inclined plane part 11, the inclined plane part 11 tilts obliquely along warpage portion 411 to 402 direction of montant；401 outer end of cross bar is hinged
Montant 402, the cooperation geosynclinal block 420 that 402 lower end of montant has and the bullet block group 30 of 3 inner end lower part of side form portion are fastened and connected；It is described
Bullet block group 30 includes movable block 31 and spring 32 that is interior positioned at side form portion 3 and moving left and right movable block 31, each cooperation
Geosynclinal block 420 has 2 ~ 4 mating grooves 421, and each mating groove 421 is fastened with a movable block 31, mating groove 421 and movable block 31
Quantity is equal；The movable block 31,421 edge rounded corner of mating groove；
The 3 inner end top of side form portion has loose slot 7, and thimble 8 is placed in loose slot 7 and thimble 8 can be in loose slot 7 up and down
Activity, the 7 lower end face montant 402 of thimble, 8 upper end of thimble have flight 71 and are limited by flight 71, screw
Cooperation screw 72,72 downward face thimble 8 of screw in slot 71；Also have between the wall surface of the lower mold portion 2 of the montant 402 and side
There is positive stop strip 9；
The pneumatic mechanism 5 connects external air source and by gas pressure band 6 muster or contraction of dynamic diaphragm.
Die sinking, the mode of operation of mold closing：Mold closing：After installing upper mold portion 1, lower mold portion 2, the lower part in side form portion 3 is fixed
Point, the cooperation geosynclinal block 420 of 402 lower end of montant is naturally close downwards；The upper part in side form portion 3 is installed, screw 72 is screwed into flight
In 71, the top of 72 top top pressure thimble 8 of screw so as to 8 lower end top pressure montant 402 of thimble, makes the mating groove of cooperation geosynclinal block 420
421 are pressed into correspondingly in movable block 31, realize and fasten, then the installation screw of installation mold；
Die sinking：Screw 72 keeps locking after installing, and is unscrewed when needing die sinking, after unscrewing screw 72 upwards, flight 71 is vacateed
Space need to only control air source pressurizing at this time, and pneumatic mechanism is heaved by gas pressure band dynamic diaphragm 6, and the diaphragm 6 heaved is very short
Top pressure warpage portion 411 in time due to leverage, 401 warpage of cross bar, and drives hinged montant 402 to tilt, montant 402
Moving up a distance in loose slot 7 makes cooperation geosynclinal block be detached from bullet block group；Air source, which has depressurized, at this time shrinks diaphragm 6, most
Only need the installation to take apart a die screw that can mold afterwards.
Above example is only to illustrate the preferred technical solution of the present invention, it is noted that for the general of the art
For logical technical staff, without departing from the principle of the present invention, several improvement made or equivalent replacement are accordingly to be regarded as this
The protection domain of invention should be covered in scope of the presently claimed invention.
