Abstract
The utility model provides a bottle cap internal expansion mold which comprises an upper mold and a lower mold. The upper mold is provide with a mold handle fixed on a pressing machine; the lower mold is fixed on a mold plate I through a guiding seat; a piston rod is arranged in the guiding seat and a hole of the mold plate I; an aluminum cylinder workpiece is arranged in the cavities of the upper mold and the lower mold; a leather bag elastic body is arranged in the aluminum cylinder workpiece, a fixed sleeve is arranged outside the leather bag elastic body, and a sealed seat sleeve is arranged at one end of the leather bag elastic body and a plurality of small steel balls are arranged in the cavity of the other end thereof; the lower mold and the guiding seat are in threaded connection; the diameter of the small steel balls are 1mm to 2mm; a mold plate II is arranged below the mold plate I and a guide pole is arranged therebetween; a spring is arranged on the guide pole and a lock nut is arranged at one end thereof; a regulating base is arranged on the mold plate II; and the regulating base is connected with one end of the piston rod through threads. When the bottle cap internal expansion mold is adopted, a hydraulic station is not needed and the internal expansion can be realized only through utilizing a conventional pressing machine, the regulation is convenient and the expansion amount can be fine-regulated; pollution caused by leakage possibly happened when hydraulic oil is used is avoided; and the product quality is improved while the service life of the mold is greatly prolonged.
Description
Technical field
The utility model relates to the bottle cap technical field, is a kind of internal expanding forming die for bottle cap specifically.
Background technology
At present, the aluminium matter bottle cap bulging of drawing tubular generally all is that rubber or polyamine fat elastomeric material are packed in the aluminum barrel, and aluminum barrel is exerted pressure by push rod in the tube in the mould of sealing, with elastomeric material crimp, reaches the purpose of bulging.Above-mentioned processing mode, elastomer is discontinuity when compression, the outer elastomeric surface distortion is big, little near the distortion of heart position, the shape of aluminum barrel workpiece in order to obtain enriching must be with the elastomer compacting, and mold clamping force is big, so elastomer is stressed also big, thereby also influenced elastomeric service life.Simultaneously upper and lower mould is the mould that merges gradually in the push rod compresses elastomeric in tube, and upper and lower mould is adjusted when bad the aluminum barrel workpiece and is easy to produce at the spue line place defective.
Summary of the invention
The utility model provides a kind of internal expanding forming die for bottle cap, has solved elastomer short, the low-quality defective of aluminum barrel workpiece bulging in service life in the background technology.
The technical solution of the utility model is achieved in that a kind of internal expanding forming die for bottle cap, comprise upper die and lower die, the die shank that is fixed on the forcing press is arranged on the patrix, counterdie is fixed on the template I by guide holder, and guide holder, template I have piston rod in the hole, and the aluminum barrel workpiece is arranged in the upper die and lower die chamber, in the aluminum barrel workpiece, establish bladder elastomer, bladder elastomer peripheral hardware fixed cover, bladder elastomer one end is established sealed socket sleeve, and a plurality of small balls are arranged in the other end chamber;
Between counterdie and the guide holder with being threaded;
Described small ball diameter is 1mm-2mm;
Template I establishes template II in the below, and guide pillar is arranged between the two, establishes spring on the guide pillar, and guide pillar one end has locking nut;
Establish the adjusting base on the template II, regulate base and link to each other with screw thread with piston rod one end.
The beneficial effects of the utility model are: the utility model need not to be equipped with Hydraulic Station, only utilize conventional forcing press can reach the interior purpose that expands, compactness reasonable in design, easy to adjust, the bulging amount is fine-tuning, the small ball calcium-base grease (big butter) that is used to transmit expansive force is lubricated, mobile very good, be similar to hydraulic drive, also solved simultaneously and utilized hydraulic oil to cause the problem that leakage pollutes easily, evenly prolong die life widely because bulging is stressed, also improved product quality simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Part explanation: 1, patrix, 2, counterdie, 3, bladder elastomer, 4, pad, 5, fixed cover, 6, sealed socket sleeve, 7, guide holder, 8, template I, 9, guide pillar, 10, piston rod, 11, regulate base, 12, template II, 13, spring, 14, locking nut, 15, the aluminum barrel workpiece, 16, die shank, 17, small ball.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described: a kind of internal expanding forming die for bottle cap, comprise patrix 1, counterdie 2, the die shank 16 that is fixed on forcing press is arranged on the patrix 1, counterdie 2 is fixed on the template I 8 by guide holder 7, between counterdie 2 and the guide holder 7 with being threaded, guide holder 7, template I is provided with piston rod 10 in 8 holes, template I establishes template II 12 in 8 belows, between template I 8 and the template II 12 guide pillar 9 is arranged, establish spring 13 on the guide pillar 9, guide pillar 9 one ends have locking nut 14, establish on the template II 12 and regulate base 11, regulating base 11 links to each other with screw thread with piston rod 10 1 ends, rotate in order to adjust bulging amount size by screw thread, patrix 1, counterdie has aluminum barrel workpiece 15 in 2 chambeies, establish bladder elastomer 3 in the aluminum barrel workpiece 15, bladder elastomer 3 peripheral hardware fixed covers 5, fixed cover 5 has two effects, the one, limit the differential expansion of bladder elastomer 3, the 2nd, be used for the location of aluminum barrel workpiece 15, bladder elastomer 3 one ends are established sealed socket sleeve 6, a plurality of small balls 17 are arranged in the other end chamber, small ball 17 diameters are 1mm, counterdie 2 bottoms have screw thread, through screwing pad 4 and sealed socket sleeve 6 are compressed bladder elastomer 3, piston rod 10 moves back and forth in bladder elastomer 3 by guide holder 7 guiding, promotes some small balls 17 and makes bladder elastomer 3 outside expansion distortion, make aluminum barrel workpiece 15 that plastic deformation take place, be adjacent to the bulging that patrix 1 and counterdie 2 are finished aluminum barrel workpiece 15.
Manufacture die shank 16 according to selected forcing press, driving patrix 1 by forcing press moves back and forth, template II12 is fixed on and has also limited counterdie all parts below 2 on the press bench, forcing press drives the aluminum barrel workpiece 15 before the bulging of packing into behind the peak of die shank 16 and 1 liter of self-enclosed height of patrix, the opening pressure machine makes patrix 1 press to counterdie 2, patrix 1 and counterdie 2 continue to press down after closing tightly, make piston rod 10 promote some small balls 17 and make it mobile, force the bladder elastomer 3 of some small ball 17 extruding, outer expanding deforms aluminum barrel workpiece 15, be adjacent to the die cavity of patrix 1 and counterdie 2, moving down also of template I 8 compressed spring 13 simultaneously, and the size of the power of bulging is to determine by the locus of adjusting piston rod 10 tops.Adjustment finishes the piston rod 10 usefulness nuts back of the body tightly on adjust base 11.Aluminum barrel workpiece 15 does not need the position of bulging to limit with fixed cover 5, and fixed cover 5 also is used for the location that is installed of aluminum barrel workpiece 15.Bladder elastomer 3 fixedly be to be locked at jam-packed between pad 4 and the sealing block set 6 mutually by counterdie 2 and guide holder 7.Patrix 1 breaks away from after bulging is finished, counterdie 2 is got back to the peak of pressure machine closed height again and is prepared the next work period, compress spring 13 simultaneously rebounds thereupon, make some small balls 17 eliminate pressure, bladder elastomer 3 also restores to the original state, make that aluminum barrel workpiece 15 is taken off, and will treat that the next aluminum barrel workpiece 15 of bulging installs on the fixed cover 5, begins next working procedure.
