ある。[Detailed description of the invention] This invention is based on a thermoforming machine in which a mold mounting table, on which a mold or a plug is attached in a replaceable manner, is attached to a stroke control device consisting of a cylinder rod installed on a fixed base. In a thermoforming machine that moves the mold or the plug in the direction of the movement line of the resin film/sheet using a stroke control device, the mold mounting table has a plurality of stoppers that move through the fixed base. The stopper rods are individually inserted into a fixed base, and a positioning piece that is movable in the moving direction of each stopper rod is installed so as to be only rotatable, and a mold is attached to the stopper rod by a stroke control device. A stopper piece is provided that stops the mold mounting table by abutting against the positioning piece as the mounting table moves a predetermined stroke in the sheet movement direction, and each positioning piece is screwed and inserted into the nut body, respectively. An interlocking endless chain is hung around the chain ring provided on each nut body, and each positioning piece is moved simultaneously by rotation linked to the chain ring and the endless interlocking chain of the nut body, with the fixed base of the mold mounting table as a reference. The feature is that the stroke of the direction of the moving line of the resin film/sheet is adjusted.

を目的とするものである。 In a thermoforming machine, the mold installed on the mold mounting table has a height that corresponds to the shape of the molded product.
Although the height varies, the line of movement of the resin film and the sheet forming are always at a constant height. In addition, it is necessary to adjust the stroke control device to move based on the movement line and stop at a fixed molding position in relation to the contact of the mold, plug, etc. with the resin film. For this reason, in the past, multiple stopper screws were provided and adjustments were made using adjustment nuts depending on the height each time the mold was replaced. In the case of the upper mold, the work had to be done on the upper surface of the upper fixed base, making the work difficult and requiring skilled hands. The object of the present invention is to improve this adjustment operation so that it is easy to do so, and also allows for free adjustment even when the vehicle is not in good condition.
