Mold clamping device and mold clamping method for upper and lower casting molds with mold box

Abstract

The present invention provides a clamping device and a clamping device for upper and lower molds of a belt box, which can actually check the state of the clamping surfaces of the upper and lower molds, the presence or absence of interference between the core and the upper and lower molds after mold clamping, and can reduce product defects. model method. A mold clamping device for clamping upper and lower molds with a top mold and a lower mold with a lower mold manufactured by a mold molding machine, comprising: the upper mold with a upper mold a lifting mechanism for lifting and lowering the casting mold; a copier drop preventing mechanism arranged under the coping box when the upper casting mold with the coping box is at the rising end to prevent the falling of the coping box; Above the box, there is a drag box floating prevention mechanism that prevents the above-mentioned drag box from floating.

Description

technical field [0001] The invention relates to a mold clamping device and a mold clamping method for upper and lower molds of a belt box manufactured by a mold molding machine. Background technique [0002] Conventionally, the upper mold of the belt-shaped box and the lower mold of the belt-shaped box manufactured by the mold molding machine are alternately arranged on a roller conveyor and conveyed. During the transportation, the upper mold of the belt-shaped box is turned over, and then the The upper and lower molds of this belt-shaped box are mold-closed and poured by a pouring machine. Furthermore, an apparatus for clamping the upper and lower molds of the belt-shaped box is known from Patent Document 1, for example. [0003] Patent Document 1: Japanese Publication No. 58-61347 [0004] However, in the device of Patent Document 1, the upper and lower molds after mold clamping are immediately carried out of the mold clamping device by the traveling trolley of the trans...

AI Technical Summary

Problems solved by technology

[0004] However, in the device of Patent Document 1, the upper and lower molds after mold clamping are immediately carried out of the mold clamping device by the traveling trolley of the traverser, and sent out to the pouring production line.

Therefore, after mold clamping, it is impossible to actually check the state of the mold clamping surfaces of the upper and lower molds, and the presence or absence of interference between the core and the upper and lower molds.

Therefore, even if there is a defect in the clamping surface of the upper and lower molds after mold closing, or if there is a defect caused by interference between the core and the upper and lower molds, the upper and lower molds have to be poured, resulting in defective products. additional questions
