5 connections.
The loose piece 801 of two 8 outer ends of type core is equipped with limited step 802,8 accurate positioning of guarantee type core.Loose piece 801 is in cunning
It slidably reciprocates, will not be skidded off outside mold 2 in slot 15, it is convenient that loose piece 801 resets, and it is accurate to reset, and type core 8 may be reused.
In the present embodiment, being equipped on pressing head seat 6 positioned at the two sides of card slot 7 can be with the inner end of pull rod 4, mold 2
The adaptable tension and compression block 601 of outer end face.Two molds 2 can be pushed to be stitched together by tension and compression block 601, it can also be by two moulds
Tool 2 is displaced outwardly and separates.
Pull rod 4 is vertically arranged, and the upper and lower ends of pull rod 4 are equipped with the connecting column 14 connect with mold 2, the two sides of pull rod 4 and
The two sidewalls of card slot 7 are adapted, and pull rod 4 can slide in card slot 7, are mutually limited by card slot 7 and pull rod 4, thus
Mold 2 is pulled to slide in and out.
In the present embodiment, push-pull mechanism 9 include connecting rod 901 and set on 901 both ends of connecting rod respectively with type core 8, push-and-pull
The hinge assembly 902 that plate 5 connects.Hinge assembly 902 includes hinged seat, and hinged seat is equipped with and the loose piece 801 of type core 8 or push-and-pull
The connecting plate that plate 5 connects, connecting plate are equipped with multiple connecting holes, and connecting plate, which protrudes above, is equipped with connection convex block, and convex block is equipped with upper
The through-hole of lower perforation setting, the both ends of connecting rod 901 are equipped with the limiting slot adaptable with the upper and lower ends for connecting convex block, connecting rod 901

When outer end is slided, on the outside of inclined-plane can squeeze the end of top pillar 12 and eject top pillar 12 to side, 10 quilt of telescopic spring bar
Location hole 11 is ejected, template 1 is separated with mold 2, and mold 2 can horizontally slip.Top pillar 12 and telescopic spring bar 10 abut against place
For round end structure.
Telescopic spring bar 10 include limited post, spring and squeeze push away screw, one end rounded corner of limited post.
The outer end of draw back plate 5 is equipped with locking pin 13, and locking pin 13 is equipped with locating cone and annular groove, and locking pin 13 is used for
It is connect with the push rod of air cylinder device or cylinder apparatus.
Implementation process: 1. this demoulding mechanism is installed on core box；2. core box to be installed to the core shooting equipment of corresponding model
On；3. penetrating sand coremaking；4. the draw back plate 5 at left and right both ends moves leftwards and rightwards under the drive of side oil pumping cylinder, due to locking mechanism pair
Mold 2, template 1 are limited, and draw back plate 5 pulls two loose pieces 801 to move along stripping direction；5. when loose piece 801 has moved to
When total pressure lives top pillar 12, two type cores 8 complete demoulding, and limited post is forced into template 1 at this time, the drawing of pull rod 4 and 7 two sides of card slot
Briquetting 601 contacts, and then the mold 2 of arranged on left and right sides starts stripping movement under the action of tension and compression block 601；6. when side oil pumping cylinder
When moving to terminal, the demoulding of left and right mold 2 is completed, and the lower core ejection mechanism below demoulding mechanism is started to work, 17 quilt of sand core
Ejection die, coring robot can take sand core 17 away.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, is not taking off
Under the premise of from structure of the invention, several modifications and improvements can also be made, these all will not influence the effect that the present invention is implemented
And patent practicability.
