Embodiment
Shown in reference picture 1- Fig. 4, in order to more clearly show that arc-shaped recess 1.1 and back-off shaped insert 1.2
Part-structure view is only depicted in detailed construction, accompanying drawing, to those skilled in the art, with reference to drawing and description,
It is sufficient to allow technical scheme to be achieved.
Demoulding mould of a kind of discoid product inner top surface arc-shaped recess and side wall back-off, including upper cores, lower die
2nd, arc-shaped recess shaped insert 3, back-off shaped insert 4, described upper cores, lower die 2, arc-shaped recess shaped insert 3 and fall
The formation formed product chamber of buckle forming insert 4；The left surface of described arc-shaped recess shaped insert 3 has one to be fixed on lower die 2
On guide pad 5, the faying face of described guide pad 5 and the left surface of arc-shaped recess shaped insert 3 is through oblique dovetail configuration phase
Match somebody with somebody；Described arc-shaped recess shaped insert 3 is located at the top of back-off shaped insert 4 and both faying faces are through oblique dovetail configuration phase
Match somebody with somebody；The lower end of described back-off shaped insert 4 connects a brace 6, and the bar portion of brace 6 tiltedly coordinates with lower die 2, brace 6
The thimble that lower end is connected on top board, top board is connected through lower die 2 with formed product chamber.
Described guide pad 5 matches with the faying face of the left surface of arc-shaped recess shaped insert 3 through oblique dovetail configuration
Refer to guide pad 5 and be provided with dovetail slide rail one, the left surface of arc-shaped recess shaped insert 3 is provided with the dovetail matched with dovetail slide rail one
Chute one；Described dovetail slide rail one is consistent with the axis direction of brace 6.
Described arc-shaped recess shaped insert 3 matches through oblique dovetail configuration with the faying face of back-off shaped insert 4 and referred to down
A dovetail slide rail two is fixed in the upper surface of buckle forming insert 4, and the lower surface of arc-shaped recess shaped insert 3 is provided with and dovetail slide rail two
Dovetail slide rail two in the dovetail chute two of matching, described back-off shaped insert 4 is in upper right side height and the low inclination in lower-left end
Shape.
Described dovetail slide rail is removably mounted at the upper surface of back-off shaped insert 4.
The lower end of described brace 6 is hinged a mounting seat 7, and mounting seat 7 is fixed on top board.
The operation principle of the present invention is, when the demoulding, and upper mould is disengaged, and top board is moved upwards in the presence of oil cylinder, pushes up
Thimble on plate heads on product and moved upwards, while top board drives mounting seat 7, mounting seat 7 drives brace 6 to move upwards, due to
Lower die 2 is fixed, and brace 6 is also being offset to the left when upward motion, the back-off shaping edge on brace 6
Block 4 is also offset while moving upwards to the left, departs from the back-off 1.2 of product；Because arc-shaped recess shaped insert 3 is respectively with falling
Buckle forming insert 4 and guide pad 5 coordinate through angularly disposed dovetail mechanism, and arc-shaped recess shaped insert 3 is in back-off shaped insert 4
Promotion under so that the speed that arc-shaped recess shaped insert 3 is moved upwards is less than the speed moved upwards of product 1.Relative to production
Product 1, the moved beneath to the left of arc-shaped recess shaped insert 3 completes the disengaging of the arc-shaped recess 1.1 of product 1.
