Description

Mount press forming mold

(1) technical field

The utility model relates to a kind of ribs of the fan making apparatus of folding fan.

(2) technical background

The making of ribs of the fan is a raw material with the strip thin bamboo plate, existing ribs of the fan profile is formed with manual lancinate method and wheel grinding method, the former cuts the type of being whittled into by skilled worker's hand-held one folded thin bamboo plate on cutter, this conventional method not ray velocity is slow, type quality is difficult to stablize, and seriously relying on operator's handicraft, the profile of ribs of the fan is difficult to be consistent; The latter becomes emery wheel making the shape of ribs of the fan one side earlier, the workman is with folded bamboo chip grinding-shaping on emery wheel, though this way requires to have reduced to workman's technical ability, speed also has quickening, and the grinding process of bamboo chip needs the water flushing, the water that washes becomes the sewage that is mixed with the bamboo powder, environmental pollution is very big, also wastes water, and the edge of bamboo chip bursts apart easily during wheel grinding in addition, the shaping back edge is coarse, and type quality is poor.

After finishing, the ribs of the fan profile also needs inner texturing, promptly on ribs of the fan, engrave out penetrating colored shape, existing texturing operation is finished on the syringe needle stamping machine one by one by the hand-held ribs of the fan of workman, because the speed of sheet, aligned position of manually changing is limited, process velocity is slow generally, the workman's that also injures easily finger.

(3) summary of the invention

The utility model will solve that existing ribs of the fan making apparatus working (machining) efficiency is low, crudy is poor, the shortcoming of contaminated environment, provides a kind of impact style that is applicable to make the diel of ribs of the fan.

Mount press forming mold described in the utility model, comprise formpiston and former, be superimposed with upper bolster, upper middle seat, top panel formation on the formpiston from top to bottom successively, upper bolster is connected by pin with upper middle seat, upper middle seat is connected by pin with top panel, have the through hole adaptive on the top panel with the upper mold core shape, upper mold core is slidably disposed in the top panel, have on the upper mold core and stop it to deviate from the block of top panel, pin is arranged at the upper mold core top, pin is through in the guide hole of upper middle seat, and the spring that is through on the described pin pushes against upper mold core in the above on the plate;

Former is superimposed with lower panel from top to bottom successively, middle seat, die shoe constitute down, lower mold core is cemented on the lower panel, seat is cemented on the die shoe down, have the through hole adaptive on the lower panel with the lower mold core shape, lower mold core is enclosed within the described through hole, on the pin during lower panel is enclosed within down on the seat, be equipped with between middle down seat and the lower panel and push against spring.

Further, be useful on the pin hole of ribs of the fan texturing on the lower mold core, the pin that dashes that cooperates with described pin hole is housed on the upper mold core.

Further, described pin hole is the shape that enlarges gradually Zi the outlet that enters the mouth.

When towards fashionable, lower panel is shunk back under spring action, and lower mold core exposes, and upper mold core is also shunk back under spring action simultaneously, and like this, lower mold core stretches in the through hole of top panel, sweeps away a slice ribs of the fan identical with the core rod shape.Pin hole is being set and under the situation of pin, more can on ribs of the fan, finishing texturing simultaneously.

The utility model has the advantages that: the production efficiency height, the profile of ribs of the fan is shaped, the disposable realization of texturing, and the ribs of the fan forming quality is stable, attractive in appearance, has broken away from the dependence to workman's handicraft, has improved the security of production environment, has reduced environmental pollution.

(5) specific embodiment

Mount press forming mold described in the utility model, comprise formpiston and former, be superimposed with upper bolster 1 on the formpiston from top to bottom successively, upper middle seat 2, top panel 3 constitutes, upper bolster 1 and upper middle seat 2 are connected by pin, upper middle seat 2 and top panel 3 are connected by pin, have the through hole 4 adaptive on the top panel 3 with the upper mold core shape, upper mold core 5 is slidably disposed in the top panel 3, have on the upper mold core 5 and stop it to deviate from the block 6 of top panel 3, pin 7 is arranged at upper mold core 5 tops, pin 7 is through in the guide hole 9 of upper middle seat, and the spring 8 that is through on the described pin 7 pushes against upper mold core 5 in the above on the plate 3;

Former is superimposed with lower panel 10 from top to bottom successively, middle seat 11, die shoe 12 constitute down, lower mold core 13 is cemented on the lower panel, seat 11 is cemented on the die shoe 12 down, have the through hole 14 adaptive on the lower panel 10 with lower mold core 13 shapes, lower mold core 13 is enclosed within the described through hole 14, on the pin 15 during lower panel 10 is enclosed within down on the seat 11, be equipped with between middle down seat 11 and the lower panel 12 and push against spring 16.

Be useful on the pin hole 17 of ribs of the fan texturing on the lower mold core 13, be equipped with on the upper mold core 5 cooperate with described pin hole 17 dash pin 18.Described pin hole 17 is the shape that enlarges gradually Zi the outlet that enters the mouth.The pin hole of common diel all is the constant straight hole of diameter, and this form is suitable for for the stamped metal part, finds but that when using with the bamboo wood punching press lower mold core is easy to cracking.Reason is that bamboo wood generally contains moisture, and the bamboo bits that sweep away are bonding in pin hole, stopped up pin hole closely, and the shock wave when causing punching press can't be dredged away, and pin hole ftractures easily.Pin hole 17 is done and is progressively expansion type, can discharge the bamboo bits effectively, makes pin hole keep mediation, effectively the punching press shock wave is dredged away, prevents the mould cracking.

When towards fashionable, lower panel 10 is shunk back under spring 16 effects, and lower mold core 13 exposes, and upper mold core 5 is also shunk back under spring 8 effects simultaneously, and like this, lower mold core 13 stretches in the through hole 4 of top panel 3, sweeps away a slice ribs of the fan identical with the core rod shape.Pin hole 17 is being set and under the situation of pin 18, more can on ribs of the fan, finishing texturing simultaneously.
