Problems solved by technology
[0002] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art. At present, after the sand box is shot and molded, the molding sand adhered to the lower platen will be cleaned by a specially designed cleaning mechanism when the sand mold is pushed out. However, for the upper flask, after the sand shot molding, the upper platen will adhere to the molding sand, but considering the action of the upper flask and the cost of the cleaning mechanism, if a cleaning mechanism is specially designed to clean the upper platen, on the one hand it will increase the manufacturing cost , In addition, it will affect the continuity of the action of the upper sand box and reduce the sand mold manufacturing efficiency of the molding machine

The invention discloses a cope flask pressing plate and a cop flask comprising the same, and relates to the technical field of molding machines. The cope flask pressing plate comprises an upper pressing plate body, wherein the bottom end surface of the upper pressing plate body is provided with a plurality of sand injection opening plates; each sand injection opening plate is provided with a sandinjection hole; the upper pressing plate body is provided with sand outlets which communicate with the corresponding sand injection holes; and the sand injection opening plates are polyformaldehyde steel material components. The bottom end surface of the upper pressing plate body is provided with the sand injection opening plates, and the sand injection opening plates are the polyformaldehyde steel material components. On one hand, since the polyformaldehyde steel material components have a low friction coefficient and good geometric stability, after moulding sand is subjected to compaction, the moulding sand is not easy to adhere. On the other hand, if individual sand injection opening plates need to be replaced, the sand injection opening plates can be singly replaced instead of a situation that all sand injection opening plates need to be replaced.
Description
technical field [0001] The invention relates to the technical field of molding machines, in particular to a pressing plate for an upper sand box, and also to an upper sand box. Background technique [0002] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art. At present, after the sand box is shot and molded, the molding sand adhered to the lower platen will be cleaned by a specially designed cleaning mechanism when the sand mold is pushed out. However, for the upper flask, after the sand shot molding, the upper platen will adhere to the molding sand, but considering the action of the upper flask and the cost of the cleaning mechanism, if a cleaning mechanism is specially designed to clean the upper platen, on the one hand it will increase the manufacturing cost , In addition, it will affect the continuity of the action of the upper sand box, and will reduce the sand mold manufacturing efficien...
