[specific embodiment]
Please refer to Fig. 2, Fig. 3, wherein Fig. 2 is painted the molding state of the external pulling type plate pushing structure of mold of the invention Schematic cross-sectional view, Fig. 3 be painted the perspective cross-sectional structural schematic diagram of part-structure in Fig. 2.
In order to achieve the above object, the mold of the back-off exit structure with inner hole side wall of the invention, mold molding 101 side wall of inner hole has the product 100 (please referring to Fig. 1) of back-off 102, which includes the upper mounted plate sequentially set up 200, caster 201, male template (not shown), male model board 202, the mold further include:
Son 203 is slided into, one end has the forming part for forming the back-off, and described slide into has sliding on son 203 Through-hole;
First enters son 204, forms the inner hole 101, and described first enters to have first through hole in son 204, described to slide into Son 203 is set to described first and enters in son 204, the side that the forming part for sliding into son 203 enters son 204 by described first It is pierced by;
Second enters son 205, is sheathed on described first and enters in son 204, and described second, which enters son 205, is held in and described slides into son 203 lower sections, described second enters to have the second through-hole in son 205;
Third enters son 206, enters 205 lower section of son set on described second, the third, which enters, has third through-hole in son 206;
Driving lever 207, has fixed part and insertion section, and the fixed part is fixed on fixed plate 200, Yu Hemo state Under, the insertion section be arranged in described first enter son 204, slide into son 203, second enter son 205 and third enter son 206 in, institute Stating insertion section has first body of rod 208, second body of rod 209, the third body of rod 210 sequentially extended downwards by the fixed part, First body of rod 208, the third body of rod 210 are vertical structure, and second body of rod 209 is incline structure, second body of rod 209 connect first body of rod 208 and the third body of rod 210.
Wherein, which also has sliding block 211, and the sliding block 211 is set in the male template, forms the product 100 Exterior contour.
Wherein, there is corresponding second body of rod 209 to tilt for the upper end and lower end of the sliding through hole for sliding into son 203 The guide part of degree, to facilitate the smooth progress stirred.
Wherein, the third body of rod 210 far from described second body of rod, 209 one end have gradient, when facilitating molding described in The insertion of driving lever 207.
Wherein, fixed block 212 is additionally provided in the male model board 202, the fixed block 212 is set to described first and enters son 204 two sides, fixed described first enters son 204.
Please refer to Fig. 4, Fig. 4 is painted the die sinking the of the mold of the back-off exit structure with inner hole side wall of the invention The schematic cross-sectional view in one stage.
After die sinking, the first stage opens between fixed plate 200 and the caster 201,207 band of driving lever The back-off 102 of the dynamic side wall for sliding into the inner hole 101 that sub 203 leave the product 100, realizes moving back for the back-off 102 Out.
Please refer to Fig. 5, Fig. 5 is painted the die sinking the of the mold of the back-off exit structure with inner hole side wall of the invention The schematic cross-sectional view of two-stage.
After die sinking, second stage is opened between the male template and the male model board 202, and described first enters 204 pine of son Move back and be detached from the inner hole 101 of the product 100.
Fig. 6 is painted the section view knot of the die sinking phase III of the mold of the back-off exit structure with inner hole side wall of the invention Structure schematic diagram.
