Description
Technical field
The invention belongs to plastic shaping field, be specifically related to a kind of plastic shaping crank press.
Background technology
At present, usually can use cultivation dish when cultivating plants new talent, the effect that cultivation dish has waterproof, protection against the tide and is incubated.Cultivation dish is generally plastic material, in order to adapt to different demands when plant new talent is cultivated, cultivation dish is processed into some specific shapes by usual needs, at present the processing of plastics cultivation dish is adopted usually to the method for mold pressing, namely processes corresponding vinyl disc by the mould of special shape.
The compression molding of cultivation dish can use forcing press usually; forcing press comprises the reciprocator of upper die and lower die and patrix, and during forcing press operation, normally counterdie is fixed on workbench; patrix moves reciprocatingly above counterdie, thus realizes compression molding and the demoulding of product.But due to only have patrix independently towards counterdie or dorsad counterdie move reciprocatingly, and counterdie keeps maintaining static, such that whole compression molding process is carried out slowly, efficiency is low; In addition, because counterdie is fixed on workbench, without buffering, damping device on workbench; and forcing press can produce vibration usually when operation; described vibration can make patrix or counterdie impaired, thus make the reduced lifetime of patrix or counterdie, namely make the cost of whole cultivation dish compression molding high.
Summary of the invention
The technical problem to be solved in the present invention be low for existing forcing press efficiency, the life-span is short thus cause the technological deficiency that compression molding cost is high, provides that a kind of efficiency is high, the life-span long thus the plastic shaping crank press making compression molding cost low.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: plastic shaping crank press, comprise rotating shaft, upper bent axle and lower bent axle, described rotating shaft is arranged with driving gear; Upper bent axle is positioned at the top of rotating shaft, lower bent axle is positioned at the below of rotating shaft, on upper bent axle, key is connected with driven gear and upper bent axle is rotatably connected to upper bush, on lower bent axle, key is connected with lower driven gear and lower bent axle is rotatably connected to lower sleeve, described upper driven gear and lower driven gear all with driving gear external toothing, described upper bush and lower sleeve with the axial line of rotating shaft for symmetry axis distributes axisymmetricly; Also comprise sliding way, glide path, upper die and lower die, upper bush is connected with connecting rod, upper connecting rod bottom is connected with top shoe, top shoe is positioned at sliding way, described patrix is connected to the bottom of top shoe, lower sleeve is connected with lower link, lower link top is connected with sliding block, sliding block is positioned at glide path, the top of sliding block is provided with groove, and bottom portion of groove is provided with spring, and described counterdie is connected to the top of spring, counterdie and groove matched in clearance, and the center line of the center line of counterdie and patrix is located along the same line.
Adopt the plastic shaping crank press of technical solution of the present invention, comprise rotating shaft, upper bent axle and lower bent axle, rotating shaft rotates for driving driving gear, and driving gear rotates for driving upper driven gear and lower driven gear; Upper driven gear is for driving upper crankshaft rotating, and lower driven gear is for driving lower crankshaft rotating, and upper bent axle moves reciprocatingly for driving patrix, and lower bent axle moves reciprocatingly for driving counterdie; Upper bent axle is provided with upper bush, and upper bush moves reciprocatingly for driving upper connecting rod, and upper connecting rod moves reciprocatingly for driving top shoe, and top shoe moves reciprocatingly for driving patrix, thus realizes the demoulding of compression molding and product; Lower bent axle is provided with lower sleeve, and lower sleeve moves reciprocatingly for driving lower link, and lower link moves reciprocatingly for driving sliding block, and sliding block moves reciprocatingly for driving counterdie, thus coordinates patrix to realize the demoulding of compression molding and product together; The top of sliding block is provided with groove, bottom portion of groove is provided with spring, and spring can patrix plays a part to cushion, damping to contacting with counterdie when counterdie and compression molding, counterdie and groove matched in clearance, thus counterdie can slide up and down in groove, and then realize the cushioning effect of spring.
Know-why of the present invention and technique effect are: due in operation process upper bush and lower sleeve all the time with the axial line of rotating shaft for symmetry axis distributes axisymmetricly, therefore upper die and lower die always do move toward one another simultaneously or do simultaneously and move dorsad, thus shorten the displacement of patrix, and then improve the frequency that patrix and counterdie meet, the cycle time of compression molding, efficiency are improved; Because counterdie bottom is provided with spring; when patrix to contact with counterdie offset and occur to vibrate time; spring can give counterdie a cushioning effect; downward displacement is there is under the action of the spring in counterdie in groove; counterdie and patrix are slowly closed up; and then it is impaired because of vibration to avoid the patrix or counterdie that cause because counterdie maintains static, thus improve the service life of upper die and lower die, reduce the cost of whole compression molding.
Further, described spring has two groups.Thus counterdie can be made more steady, avoid counterdie run-off the straight and with recess sidewall friction.
Further, the often group spring in described two groups of springs includes big spring and little spring, and little spring is positioned at big spring, and the top of little spring is all connected with counterdie with the top of big spring.Thus when a spring ruptures because occurring to resonate with counterdie, an other spring can also be had to compensate, to ensure carrying out smoothly of compression molding.
Further, the rotation direction of described big spring and little spring is contrary.Thus big spring and little spring can be avoided mutually to interfere.
Further, described rotating shaft is also provided with brake.Thus the motion of upper die and lower die can be controlled.
