A kind of thermoforming machine
Technical field
The utility model relates to a kind of thermoforming machine.
Background technology
Existing thermoforming machine generally comprises horizontal base, vertical pedestal, guide pillar, upper bolster, die shoe and die shoe drive unit; Above-mentioned vertical pedestal generally is installed on the horizontal base by bolting, above-mentioned guide pillar is installed on the vertical pedestal vertically, upper bolster is fixedly mounted on the upper end of guide pillar, and die shoe can slide up and down to be installed on the guide pillar by guide pin bushing, and die shoe is vertically between pedestal and the upper bolster; The die shoe drive unit comprises hydraulic jack and die shoe transmission device, the die shoe transmission device comprises hinged seat, intermediate transmission mechanism and following hinged seat, last hinged seat generally is installed on the die shoe by bolting, following hinged seat generally is installed on the horizontal base by bolting, the upper end of intermediate transmission mechanism and last hinged seat are hinged, and the lower end of intermediate transmission mechanism is hinged with following hinged seat; The cylinder body of above-mentioned hydraulic jack is installed on the horizontal base vertically, and the piston rod and the intermediate transmission mechanism of hydraulic jack are in transmission connection.
During compression molding,, make hydraulic jack drive die shoe and move up and down, thereby make counterdie and the patrix on the upper bolster on the die shoe realize matched moulds and die sinking along guide pillar by intermediate transmission mechanism by the stroke of hydraulic jack is set.
Because vertically pedestal is installed in horizontal base, goes up hinged seat and be installed in the upper and lower hinged seat of die shoe by bolting and be installed on the horizontal base by bolting by bolting, above-mentioned bolted structural strength is poor, and the impulsive force that thermoforming machine produces when matched moulds is bigger, so, above-mentioned bolt ease of connection takes place loosening, therefore, causing easily that whole thermoforming machine produces beats, thereby the operation stability that makes whole thermoforming machine is poor, noise is big, also has influence on the service life of each parts of thermoforming machine simultaneously; Take place to become flexible if above-mentioned bolt connects, will cause the power transmission inaccuracy of die shoe drive unit, just can have influence on the accuracy of matched moulds like this, thus cause percent defective to improve, reduced production efficiency.
Summary of the invention
The technical problems to be solved in the utility model provides that a kind of structural strength is good, stable, closing precision is high, the thermoforming machine of long service life.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
