All-in-one machine for vacuum forming, molding and punching

The invention relates to an all-in-one machine for vacuum forming, molding and punching, comprising a rack, a material traction device, a heating device, a forming unit, a punching device and a control device; wherein a top die platform and a bottom die platform of the forming device are provided with moulding moulds which are thereupon provided with a convex part or a concave part for forming a light trapping bump on plastic sheets; the punching device comprises a punching shear mechanism, a guide rail which moves frontwards and backwards and a photocell eye for detecting the light trapping bump; the guide rail is arranged in the front of the punching shear mechanism, the photocell eye is arranged in the front of the punching shear mechanism and is connected with a corresponding input terminal corresponding to the control device.In the invention, when forming is carried out, the light trap bump can be formed on the plastic sheet, the flaky plastic products can be prevented from transversely displacing by the guide of the guide rail, the photocell eye can be used to detect the light trap bump and the control device can be used to lead the material traction device to convey the flaky plastic products to preset distance, so that the longitudinal position of the plastic products is accurate when the plastic products enter the punching shear mechanism and the flaky plastic products can accurately arrive at the preset position of the punching mechanism.
