Abstract
The utility model discloses an auxiliary stretching device of a plastic molding machine, which comprises a platform support (1). The auxiliary stretching device is characterized in that the device also comprises a motor (2), a mounting rack (3), a screw (4), a nut (5), a guide pillar (6) and a guide sleeve (7). The screw and the guide sleeve are arranged on the mounting rack; the screw is connected with the motor; the guide pillar is matched with the guide sleeve and one end of the guide pillar is fixedly connected with the nut, the other end of the guide pillar is fixedly connected with the auxiliary platform support. The auxiliary stretching device has the advantages of high molding quality achieved by accurately and conveniently controlling the feeding speed, convenient adjustment, low noise and saved energy.
Description
[technical field]
The utility model relates to a kind of plastic product molding machine, what be specifically related to is a kind of auxiliary stretching device of plastic product molding machine.
[background technology]
Plastic product molding machine is to produce plastic products (as plastic cup, plastic bowl) equipment, mainly contain just molded and the vacuum forming dual mode, auxiliary stretching device is that plastic product molding machine is in the plastic product forming process, for guaranteeing what Forming Quality was provided with, its main executive component is a cylinder, operation principle is: if adopt the malleation molding mode, before plastic product forming, cylinder promotes the assistance platform support, the auxiliary mould that is installed on the assistance platform support carries out preformed to plastic sheet, the plastic sheet of source of the gas after to preformed blown then, makes it moulding; If adopt the vacuum forming mode, before plastic product forming, cylinder promotes the assistance platform support, and with before mould contacts, source of the gas begins air-breathing, and both preformed stages, with after mould contacts, the moulding of plastic sheet is finished in air-breathing continuation.Preformed effect is exactly that material is out of shape in advance, and the excessive product that brings of material deformation draws problem bad, that Forming Quality is not high when preventing moulding.Yet cylinder is as executive component, there is following shortcoming in it: the fltting speed of cylinder control assistance platform support is controlled by bleed pressure, regulate inconvenient, inaccurate, air consumption is big, noise is big, and fltting speed is a key factor that guarantees good Forming Quality; When adopting the malleation molding mode, need control different propelling positions in addition, both need often to regulate the stopping means of cylinder, regulate very inconvenient the shaped article of difformity, different materials.
[summary of the invention]
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of accurate convenient control feed speed to reach the auxiliary stretching device of high Forming Quality, easy to adjust, plastic product molding machine that noise is little, energy-conservation.
For solving the problems of the technologies described above, the utility model takes following technical scheme to finish:
A kind of auxiliary stretching device of plastic product molding machine comprises the assistance platform support, it is characterized in that: described auxiliary stretching device also comprises motor, installing rack, screw rod, nut, guide pillar, guide pin bushing; Described screw rod, guide pin bushing are located on the installing rack; Described screw rod is connected with described motor; Described guide pillar cooperates with described guide pin bushing, and an end and described nut are affixed, and the other end and described assistance platform support are affixed.Described motor is servomotor or stepper motor.
Should adopt the driven by motor screw rod to rotate by auxiliary stretching device, thereby promote nut, and nut is installed on the guide pillar, rotatablely moving of motor just converts the rectilinear motion of guide pillar to like this, realizes and the same rectilinear motion function of cylinder.And with the mode of servomotor or step motor control have accurate convenient control fltting speed with reach high Forming Quality, easy to adjust, noise is little, energy-saving advantages.
[description of drawings]
The utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model
Fig. 2 installs and uses figure for the utility model on Pneumatic hot plastic molding machine
Fig. 3 installs and uses figure for the utility model on plastics vacuum thermoforming machine
[specific embodiment]
Accompanying drawing has been represented the technical solution of the utility model and embodiment, further describes each relevant details and operation principle thereof of embodiment below more in conjunction with the accompanying drawings.
With reference to accompanying drawing 1, the auxiliary stretching device of this plastic product molding machine comprises assistance platform support 1, servomotor 2, installing rack 3, screw rod 4, nut 5, guide pillar 6, guide pin bushing 7, described screw rod 4 is installed on the described installing rack 3 by the bearing at two ends, and be connected with described servomotor 2 by shaft coupling, on described installing rack, also be provided with described guide pin bushing 7, described guide pillar 6 cooperates with guide pin bushing, can in guide pin bushing, slide, one end and the described nut 5 of guide pillar are affixed, and the other end and described assistance platform support 1 are affixed.Certainly, described screw rod also can be in transmission connection by other kind of drive and described servomotor.
Before the plastic product molding machine moulding, servomotor drives screw rod and rotates, thereby promotes nut, and nut is installed on the guide pillar, and rotatablely moving of motor just converts the rectilinear motion of guide pillar to like this, promotes the assistance platform support, finishes later shaping work.Servomotor can conveniently be controlled the size of rotating speed, reaching suitable fltting speed, thereby reaches high Forming Quality; Simultaneously, servomotor can accurately be controlled stroke, and so just having avoided needs often to regulate the trouble of stopping means to the shaped article of difformity, different materials when adopting the malleation molding mode; And servomotor also has little, the energy-saving advantages of noise.Accompanying drawing 2 and accompanying drawing 3 are respectively the use installation diagram of the utility model on Pneumatic hot plastic molding machine and plastics vacuum thermoforming machine.
In sum, adopt the auxiliary stretching device of technique scheme, the plastic products product quality of plastic product molding machine be improved, and easy to adjust, noise is little, energy-conservation, will bring very big facility and positive result of use to the user.
