Connect, and the second tilted footstock 11 can carry out vertical direction movement along the angle of inclination of the axis of tilted footstock guide pillar 7, then by tilted footstock
6 are arranged on die main body 1, and front panel 13 is provided with die main body 1, and front panel 13 is provided with accommodating chamber 17, by oblique top
Seat 6 is arranged in accommodating chamber 17, the first tilted footstock 10 is connected in the accommodating chamber 17 of front panel 13, by screw by the first oblique top
Seat 10 is locked on front panel 13, and preceding internal model 15 is provided with front panel 13, and the preceding internal model 15 is provided with oblique top assembling
Hole, the oblique top 8 is arranged in the oblique top pilot hole of preceding internal model 15, and extends to the second tilted footstock 11 and be embedded into the second tilted footstock
In 11, oblique top 8 is fixed on the second tilted footstock 11 by screw.
Finally, tilted footstock reset pin 9 is fixedly mounted in rear internal model 16, and rear internal model 16 is arranged on rear board 14
On, then assembled successively the flow distribution plate 12 after component, front panel 13 and rear board 14 is installed, be equipped with mold top panel, under
The general purpose modules such as panel, just complete the assembling of whole mould.
When die main body 1 is in die opening state, to movement, each component is with front panel for front panel 13 and rear board 14 pairs
13 and the movement of rear board 14 carry out stripping operation, during die sinking, due to tilted footstock reset pin 9 as rear board 14 is moved down,
In moving process, cause tilted footstock reset pin 9 to relieve and state is held out against to the second tilted footstock 11, meanwhile, in being compacted state
4 pairs of the second tilted footstocks 11 of spring carry out elastic force ejection, the second tilted footstock 11 is acted on due to the elastic force by spring 4, just along
The central axis of tilted footstock guide pillar 7 is moved down, and the stroke of the second tilted footstock 11 is limited by preceding internal model 15, in the second tilted footstock 11
Move to when at preceding internal model 15, by the rigid limit of preceding internal model 15, so as to stop the second tilted footstock 11 because of the shifting of the elastic force of spring 4
Dynamic, oblique top 8 that is embedded and being fixed on the second tilted footstock 11 is also moved down therewith so that oblique top 8 depart from product it is interior fall
Button realizes the demoulding of product.
When die main body 1 is in matched moulds state, front panel 13 and rear board 14 are moved towards, and each component is with front panel
13 and the movement of rear board 14 resetted, during matched moulds, because rear board 14 is moved up, make setting rear internal model 16 in the inner
Also in the lump with moving up, so as to make tilted footstock reset pin 9 be moved up also with rear board 14, in moving process, tiltedly
Footstock reset pin 9 is butted on the second tilted footstock 11 because moving up, and with moving process, and tilted footstock reset pin 9 is by
The upward ejection of two tilted footstock 11, makes the second tilted footstock 11 be offset up along the central axis of tilted footstock guide pillar 7, simultaneously as
Moving up for second tilted footstock 11, makes the also upper shifting in the lump of oblique top 8 being arranged on, under the ejection of tilted footstock reset pin 9,
Second tilted footstock 11 is moved upward to and is fitted with the first tilted footstock 10, spacing by the first tilted footstock 10 and stop continuing to move
Dynamic, in the process, there is elasticity pressure in spring 4 by the pressure caused to it in the moving process of the second tilted footstock 11 again
Contracting, after being closed to front panel 13 and rear board 14, just completes a mould assembling action.
The above, is only presently preferred embodiments of the present invention, not technical scope of the invention is imposed any restrictions, one's own profession
The technical staff of industry, under the inspiration of the technical program, can make some deformations and modification, every according to technology of the invention
Any modification, equivalent variations and modification that embodiment of the essence to more than is made, still fall within the scope of technical solution of the present invention
It is interior.
