Problems solved by technology

[0003] Although the mold with thimble plate is convenient for product demoulding, it also causes another problem, that is, if the thimble on the thimble plate cannot be reset in advance during the mold closing process, the front and rear mold bases will be broken during the mold closing process. It is easy to cause interference and collision between the slider on the mold and the thimble and cylinder on the ejector plate, and then easily damage the mold

Abstract

The invention provides a mold ejection resetting detector which is fixed on a mold plate. The mold ejection resetting detector comprises an ejector plate with a groove, a detecting rod, a limit screw, a reset spring, a photoelectric switch and a screw plug. The mold ejection resetting detector has the advantages that the tip of the front end of the detecting rod is accommodated in the groove on the ejector plate, and a free end of the rear end of the detecting rod is accommodated in an accommodating groove and contacts with a sensing piece to enable the ejector plate to be capable of moving up and down under the action of coordination of the photoelectric switch and a cabinet, so that automatic resetting of the ejector plate can be achieved.

Description

technical field [0001] The invention relates to a detection device, in particular to a mold ejection reset detection device, which belongs to the technical field of injection mold products. Background technique [0002] Injection molds generally include a front mold base and a rear mold base that form the mold cavity. During injection molding, the two mold bases are closed, and the raw material enters the mold cavity through the feeding hole. After the injection molding is completed, the two mold bases are separated, so that the molded The product is taken out from the cavity. In order to facilitate the separation of the product from the mold, an ejector plate is usually set in one of the molds, so that the product is pushed out of the cavity through the ejector plate. [0003] Although the mold with thimble plate is convenient for product demoulding, it also causes another problem, that is, if the thimble on the thimble plate cannot be reset in advance during the mold clos...
