Embodiment Construction
[0015] The present invention is further described below with embodiment.
[0016] Seen from the figure, the present invention selects the integral steel according to the size of the vacuum calibrating plate, and is provided with some air passages 6 and water passages 8 processed by the deep hole processing method inside, and a part of the vacuum calibrating plate front 1 is provided with a depth less than 1mm (actually 0.6 mm) reticulated groove 3, on which a plurality of vacuum suction ports 5 communicating with the air passage 6 are processed, and the two ends of the air passage are blocked with silk plugs 7; the other part of the front is provided with a number of holes with a depth less than 1mm (actually 0.6mm). The straight groove 4 is also processed with a plurality of vacuum suction ports 5 communicated with the air passage 6; the reverse side 2 of the vacuum sizing plate is provided with a number of interfaces 9 connected with the vacuum suction pipes, and the interfac...

The invention provides a novel whole vacuum molding plate for a hollow plate plastic molding machine. Whole steel is selected for the vacuum molding plate according to the size of the vacuum molding plate, several water channels and air channels are obtained through deep hole processing, the positive surface of the vacuum molding plate is provided with a chequered groove and several straight grain grooves, the chequered groove and the straight grain grooves are respectively provided with a plurality of vacuum suction ports communicated with the air channels, and two ends of each of the air channels are blocked off by plugs; and the negative surface of the vacuum molding plate is provided with several interfaces connected with a vacuum suction tube, the interfaces are communicated with the air channels, and the vacuum suction interfaces which are connected with a total air collection tank are connected with a vacuum pump. Two ends of the vacuum molding plate are seal-connected by a side seal plate of communication slots communicating the water channels in a series or parallel or series and parallel mode to reach a best cooling effect. The whole structure of the vacuum molding plate, which has the advantages of no fear of deformation, good cooling effect, small maintenance amount, uniform distribution of vacuum in the vacuum molding plate, strong vacuum adsorbility, substantial reduction of the power of the vacuum pump, and substantial improvement of the product quality and the production efficiency.
Description
technical field [0001] The invention relates to a hollow plate plastic forming machine for production equipment of packaging materials, turnover boxes and building decoration materials, in particular to an integral vacuum-setting plate for the hollow plate plastic forming machine. Background technique [0002] The development of modern packaging, turnover boxes, and building decoration materials is changing with each passing day, and there are many varieties. Among them, the hollow board plastic panel material is widely used, and it is produced on a large hollow board plastic molding machine. Its vacuum-set sheet is its key component. Old-fashioned vacuum sizing plates usually have two structures. One is to machine the water channel and air channel on the base plate, and then seal it with a cover plate, and connect the cooling water channel tube and the vacuum air channel tube on both sides. Due to the large size, large area and poor working conditions of the vacuum sizing...
