Abstract

PURPOSE:To simplify the mechanism of a molding machine for molds in said machine by sticking a squeezing board above a lower squeezing table which is movable upward and downward, and installing a lower flask provided with a blow port for molding sand above said board. CONSTITUTION:An upper squeezing board 15 is stuck above a lower squeezing table 8 which is movable upward and downward by facing said table, and a lower flask 13 having an opening into which the table 8 can fit and provided with a blow port 12 for molding sand on the side wall surface is provided right above the table 8 movably upward and downward independently from the table 8. An upper flask 18 having openings through which the board 15 can fit on the top and bottom surfaces and provided with a blow part 17 for molding sand on the side wall surface is provided right under the board 15 movably upward and downward and stoppably in the midway. Further a match plate 25 is installed between the flask 18 and the flask 13 freely movably in and out, whereby the mechanism over the entire part of the molding machine is simplified and equipment costs are reduced.

Conventionally, a match plate (a plate material with models attached to both the top and bottom sides) was placed between the upper and upper casting flasks, and the upper and upper casting flasks were operated simultaneously to clamp the match plate from both the upper and lower sides. In the past, molding sand was simultaneously blown into the space defined by the upper and lower flasks and the pine plate, and then squeezed from both the upper and lower sides using the upper and lower squeeze tables to create the mold. According to the above, the upper and lower flasks and the upper and lower squeeze tables had to be operated simultaneously, which complicated the mechanism, required a large installation area, and was economically disadvantageous. .

In addition, synchronized operation is difficult because it is necessary to simultaneously operate mold matching, soil removal for squeezing, the upper flask, or the upper and lower squeeze tables, so for example, either the upper squeeze table or the lower squeeze table enters the squeeze operation faster. If a concentrated load is applied from one side of the match plate,
There were problems such as damage to the match plate.

Next, when the upper frame cylinder (16) is unclosed and the lower frame cylinder (11) is operated, the upper frame (18) as well as the lower frame (13) are abutted and supported by the lower frame (13). The molds in the upper and lower frames (13) and (18) are pushed upward and placed on the top surface of the lower squeeze table (8) in the state of stacked completed molds. After extraction, the squeeze cylinder (7) is operated in reverse, and the lower squeeze table (8) on which the completed mold is placed descends to its original position.The mold ejection cylinder (59) is operated, and the upper surface of the lower squeeze table (8) is operated. The completed mold (70) is pushed by the mold extrusion plate (62) and sent out onto the mold transport conveyor (65) via the mold transport table (64). After sending out, the mold extrusion cylinder (59) is reversely operated and when it retreats to a predetermined position, the lower frame cylinder (11) and upper frame cylinder (16) are reversely operated, and the lower frame (13) and upper frame (18) are reversely operated.

In short, the present invention has an upper squeeze board fixed above a pair of lower squeeze tables that can be raised and lowered, and has an opening on the lower surface directly above the lower squeeze board large enough to fit the lower squeeze table. In addition, a lower frame equipped with a molding sand inlet on the side wall surface is provided so as to be movable up and down independently of the lower squeeze table, and a lower frame of a size that allows the upper squeeze board to be fitted is provided directly below the upper squeeze board. An upper frame with openings on the upper and lower surfaces and a molding sand inlet on the side wall surface is provided so that it can be stopped midway up and down, and a match plate is provided between the upper frame and the lower frame so that it can be moved in and out. This structure simplifies the mechanism, reduces equipment costs, and eliminates the need to simultaneously operate the upper and lower flasks or the upper and lower squeeze tables during mold matching or squeezing. A concentrated load may be applied to the match plate from only one side, and therefore the match plate
It has various excellent effects such as no problem of damage to the parts, and its contribution to this type of industry is significant.
