Abstract

PURPOSE:To form a single sheet made of synthetic resin without much heat loss and necessity for wide space by transferring the sheets mutually between two units simultaneously, while the sheet is heat-treated in parallel with forming cycle. CONSTITUTION:An upper die 20 is raised when forming is finished, and a lower die 21 is let down after a formed sheet product is cooled, and then a cramp frame-check member 68 is elevated. Consequently, a cramp frame 63 is elastically supported on a cramp frame-receiving member 25, 26 with a constant distance from said members by the elastic force of a supporting spring. The finished sheet product is taken out of a sheet-feeding port combined with a sheet- pulling out port by opening a cramp frame 63, and simultaneously from this port, a new sheet 67 is fed into a forming unit 2 and cramped by the cramp frame 63. Thus, taking out the finished sheet product and feeding the sheet are carried out in the forming cycle for the sheet 67 at the side of the forming unit 2, and simultaneously the sheet 67 is heat-treated in said forming cycle of the sheet in parallel with the cycle at the side of the heating unit 3.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a veneer molding method and a molding apparatus directly used in this molding method, and more specifically, to a veneer molding method and a molding apparatus directly used in this molding method, and more specifically, to a veneer molding method and a molding apparatus directly used in this molding method. Plate sheet) 1. Vacuum Wt type method for forming into a certain shape and 7.
It relates to shaped devices.

In the conventional type of forming apparatus used for sheet forming, a heating heater is placed adjacent to the sheet forming position and can be moved forward and backward toward the forming position. Then, during sheet forming, the heating heater moves forward and is positioned at the sheet forming position, and the veneer sheet held in the corresponding position is
It is heated for a predetermined time to soften it, and when the heating of the sheet is finished, the heating heater Fi retreats and returns to its original position.
It waits until the next new sheet is fed to the sheet forming position. However, since the heating heater is in the heating state at the time of waiting, the heat loss is large and the workability is not as good as expected. Each sheet 1. There is a molding device that heats the heater by moving it back and forth in the center, but according to this conventional method, the sheet is heated and then moves back and forth overnight to constantly keep the sheet in each grade position. ) Since it requires 1 heating, it has the advantage that there is less loss of heat, but it also requires one mold, which increases the cost. In addition, even if you try to mold a product using both of the above acid molds, it will be impossible to mold the products of Group 1 at the same time because the heating time will differ depending on the size and thickness of the sheet. However, it was not possible to use it at the appropriate time, and the range of overuse was limited.

In addition, the conventional Sea 1 Sugi Sogeki is equipped with a turntable circle W4g4 that rotates intermittently to supply and take out sheets 1L.
A sheet heating position and a sheet rolling position are provided, and when the sheet is fed at the sheet feeding position, the turntable Fi intermittently rotates slowly, and the sheet is heated at the heating position and shaped into a predetermined shape at the nine bale forming position. There are four types that are molded and taken out as a sheet molded product from the sheet removal point and made into a stone-like shape. However, this method had the disadvantage that the entire painting process was large, requiring a large warehouse space, and the cost was high.

In view of the above points, the present invention provides a system in which a molding unit and a heating unit are installed side by side in a pair, and a sheet is supplied, molded and sealed within a molding cycle. By heating the sheet in parallel with this in the cycle and simultaneously transferring the sheet between each of the above units by appropriate means, there is little heat loss and a compact and large heavy duty space is achieved.
