Abstract

The utility model relates to a pneumatic type thermal shaping machine, which belongs to the improvement of a solid plastic pneumatic type thermal shaping machine; the pneumatic type thermal shaping machine comprises a base, a pull rod, an upper fixed die plate, a lower fixed die plate, an upper die arranged on the upper fixed die plate, and a lower die arranged on the middle moving die plate; a double toggle rod can be arranged between the lower fixed die plate and the middle moving die plate, and the fixed rod of the double toggle rod can be connected with a matched die oil cylinder. The pneumatic type thermal shaping machine adopts a double toggle rod structure, the construction of the pneumatic type thermal shaping machine in the prior art can be reduced, the manufacture cost can be reduced, and meanwhile, the pneumatic type thermal shaping machine has less power consumption, and long service life; the pneumatic type thermal shaping machine of the utility model is the improvement for the pneumatic type thermal shaping machine.

Description

Pneumatic thermoforming machine

The utility model belongs to the improvement of solid phase Pneumatic hot plastic molding machine.

The full-automatic solid phase thermoforming machine for plastics of C600-K in the market, its shaping mechanism is to be started by main electrical equipment control stepless speed-regulating motor, drive spindle cam, the operation of control push rod, thereby controlled the answer operation of sleiding form, but, need high-powerly could satisfy the locked mode requirement when causing electric motor starting because the pressure angle of cam is big, its power consumption is big and cam wear is fast, influences complete machine service life.

In view of the deficiencies in the prior art, the purpose of this utility model aims to provide a kind of pneumatic thermoforming machine that uses small-power also can reach the locked mode requirement.

The utility model is finished as follows: the utility model comprises support, pull bar, last fixed form, following fixed form, middle moving die plate, is located at the mold on the fixed form, be located at the bed die on the moving die plate, between described fixed form and middle moving die plate, the duplex bar be set.

Above-mentioned duplex bar is formed by connecting by upper elbow lever, lower elbow lever, connecting rod, fixed bar.

Above-mentioned lower elbow lever is seven font bars.

Fixed bar in the above-mentioned duplex bar is connected with die cylinder.

The utility model compared with prior art, and is simple in structure, power consumption is low, long service life, and uses small-power to realize big clamp force, also reduced production cost when having reduced manufacturing cost.As: adopt 65 kilograms per centimeter ²The oil pressure oil cylinder, its thrust is 7.2 tons, has produced 90 tons clamp force, increases multiple and can reach 12.5 usually.

The utility model has following accompanying drawing

Structure chart when Fig. 1 is the utility model die opening state

Structure chart when Fig. 2 is the utility model matched moulds state

Accompanying drawing has been represented structure of the present utility model, in conjunction with the embodiments structure of the present utility model and principle thereof is further elaborated below again.The utility model comprises support 9, pull bar 2, goes up fixed form 1, down fixed form 7, middle moving die plate 5, be located at mold 3 on the fixed form 1, be located in bed die 4 on the moving die plate 5, between described fixed form 7 down and middle moving die plate 5, duplex bar 6 is set.Described duplex bar 6 is formed by connecting by upper elbow lever 10, lower elbow lever 11, connecting rod 12, fixed bar 13, and described lower elbow lever 11 is seven font bars, and described fixed bar 13 is connected with die cylinder 8.During work, when after plastic material is by preheating, resting between the upper and lower mould, drive duplex bar 6 by die cylinder 8 and make fluid motion, moving die plate 5 is done the operation of rising in the drive, thereby it is up to drive bed die 4, realizes that upper and lower mould matched moulds pins, in like manner, during die sinking, duplex bar 6 resets, and moving die plate 5 is descending in the drive, realizes die sinking, back and forth operation thus reaches alternately locked mode, die sinking.Adopting the utility model duplex bar structure, simplified the structure of former air pressure thermoforming machine greatly, reduced low, the long service life of manufacturing cost and power consumption, is one of pneumatic thermoforming machine to be created greatly change.
