The specific embodiment
By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with embodiment and conjunction with figs. and give explanation.
See also Fig. 1 and Fig. 2, the utility model mould 100 is used for forming plastic cement product 200, this plastic cement products 200 have a side recessed/side protuberance 201, this mould 100 comprises a master mold 10 and one and the male model 20 of master mold 10 mutual corresponding matching.
Said master mold 10 has a mother module core 11.
Said male model 20 comprises a male model benevolence 21, internal core-pulling mechanism and ejecting mechanism; Offer a movable chamber 211 on the male model benevolence 21; Internal core-pulling mechanism comprises at least one movable jacking block 221, at least one spring 222 and at least one movable hoodle of being located between spring 222 and the movable jacking block 221 223 that is placed in the movable chamber 211 and can recessed along side in movable chamber 211/side protuberance 201 bearing of trend overturnings; On the movable jacking block 221 respective side recessed/side protuberance 201 is provided with a forming part 225; Movable jacking block 221 bottom surfaces, inner surface and outer surface are equipped with the inclined plane; Particularly, the inclined plane comprises first inclined plane 2211, second inclined plane 2222 on the inner surface and the 3rd inclined plane 2223 on the outer surface on the bottom surface; The bottom surface of male model benevolence 21 corresponding movable jacking block 221 in 211 lower ends, movable chamber offers the fluting 226 that is communicated with movable chamber 211, and spring 222 and movable hoodle 223 are placed in slots in 226; Movable jacking block 221 outsides of male model benevolence 21 in movable chamber 211 fixedly are equiped with a latch segment 227.Ejecting mechanism comprises thimble 224, and thimble 224 passes male model benevolence 21 and is resisted against product 200.
Wherein, thus spring 222 can flexibly replace movable hoodle 223 so replace movable jacking block 221 inwardly rollover make forming part 225 break away from the side of products 200 recessed/side protuberance 201, during die sinking, spring 222 is not in compressive state.
During 100 assemblings of the utility model mould, movable jacking block 221 is assembled in 211 inboards, movable chamber, and latch segment 227 is fixed at movable jacking block 221 outsides in the movable chamber 211, so that movable jacking block 221 is limited in the movable chamber 211.Movable hoodle 223 and spring 222 are placed in the fluting 226; Movable hoodle 223 be positioned at movable jacking block 221 and spring 222 between; Rely on locking member (indicating among the figure) the 226 bottoms sealing of will slot again, thus, movable hoodle 223 can be in the butted bottom surface of descending to replace movable slider 221 of spring 222.
During the utility model mould 100 matched moulds states; As shown in Figure 1; Master mold 10 and male model 20 matched moulds, mother module core 11 compresses movable slider 221 end faces, makes movable slider 221 bottom surfaces compress movable hoodle 223; Spring 222 compression, first inclined plane 2211, second inclined plane 2222 and the 3rd inclined plane 2223 all do not contact with other part.
During 100 die sinkings of the utility model mould, as shown in Figure 3, male model 20 is away from master mold 10; Spring 222 elasticity are replaced movable hoodle 223 and then pushing and pressing activity jacking block 221 bottom surfaces, movable jacking block 221 inside overturnings, and its lateral tilts; Inboard downward-sloping, first inclined plane 2211 reclines to movable chamber 211 diapires, and second inclined plane 2222 reclines to movable chamber 211 madial walls; The 3rd inclined plane 2223 reclines to latch segment 227, thus forming part 225 break away from the side of products 200 recessed/side protuberance 201; The side that breaks away from product 200 for to be formed 225 fully is recessed/side protuberance 201 after, the thimble 224 of ejecting mechanism ejects product 200 fully; Then, mould 100 beginning matched moulds, so back and forth.
In sum; The internal core-pulling mechanism of the utility model mould 100 can flexibly be replaced movable hoodle 223 by means of spring 222 and then replace movable jacking block 221 and inwardly turn on one's side; Thereby make forming part 225 break away from the side of products 200 recessed/side protuberance 201; Accomplish product 200 demouldings, its assembling is simple, and production cost is low.
