Detailed description of the invention
Shown in Fig. 1-Fig. 4, in order to can the detailed construction of display arc-shaped recess 1.1 clearly and the shaping insert 1.2 of back-off, only depict part-structure view in accompanying drawing, to those skilled in the art, by reference to the accompanying drawings and description, be enough to allow technical scheme of the present invention be achieved.
A kind of discoid product inner top surface arc-shaped recess and sidewall back-off demoulding mould, comprise upper cores, lower die 2, the shaping insert of arc-shaped recess 3, the shaping insert 4 of back-off, described upper cores, lower die 2, the shaping insert of arc-shaped recess 3 and the shaping insert 4 of back-off form formed product chamber; The left surface of the shaping insert of described arc-shaped recess 3 has a guide pad 5 be fixed on lower die 2, and described guide pad 5 matches through oblique dovetail configuration with the faying face of the left surface of the shaping insert of arc-shaped recess 3; The shaping insert of described arc-shaped recess 3 is positioned at above the shaping insert of back-off 4 and both faying faces match through oblique dovetail configuration; The lower end of the shaping insert 4 of described back-off connects a brace 6, and the bar portion of brace 6 tiltedly coordinates with lower die 2, and the lower end of brace 6 is connected to top board, and the thimble on top board runs through lower die 2 and is communicated with formed product chamber.
Described guide pad 5 matches through oblique dovetail configuration with the faying face of the left surface of the shaping insert of arc-shaped recess 3 and refers to that guide pad 5 is provided with dovetail slide rail, and the left surface of the left surface of the shaping insert 3 of arc-shaped recess is provided with the dovetail chute matched with dovetail slide rail; Described dovetail slide rail is consistent with the axis direction of brace 6.
The shaping insert of described arc-shaped recess 3 and back-off shaping insert 4 faying face match through oblique dovetail configuration and refer to that a dovetail slide rail is fixed in the upper surface of the shaping insert 4 of back-off, the lower surface of the shaping insert 3 of arc-shaped recess is provided with the dovetail chute matched with dovetail slide rail, and the dovetail slide rail in the shaping insert of described back-off 4 is low skewed of the high and lower-left end of upper right side.
