Inclined lifting pin fixing structure easy to maintain

Abstract

The invention discloses an inclined lifting pin fixing structure easy to maintain. The inclined lifting pin fixing structure comprises a lower mold; an inclined surface groove is formed in the lower mold; an inclined ejector for ejecting out products on the lower mold is arranged in the inclined surface groove; the inclined ejector comprises an inclined ejector rod and an inclined ejector block; the inclined ejector block is fixed at one end of the inclined ejector rod through a bolt; a through hole for inserting in the bolt and fixing the inclined ejector rod is formed in one side of the inclined ejector block; an ejection hole communicating with the through hole is formed in the other side of the inclined ejector block; and the diameter of the ejection hole is smaller than the diameter of the through hole. The inclined surface groove is provided with the through hole for inserting in the bolt at one end and the ejection hole at the other end; the diameter of the ejection hole is smaller than the diameter of the through hole; and a step surface formed by the two holes achieves a bolt stop function, so that the bolt release accident rate is reduced, and the cost is reduced.

Description

【Technical field】 [0001] The invention belongs to the technical field of machinery, and in particular relates to an easy-maintenance tilting pin fixing structure. 【Background technique】 [0002] In plastic molds, the ejection mechanism includes straight top and inclined top. The function of the inclined top is to eject the product while releasing the horizontal undercut. The plug of the inclined top generally adopts a through hole, and the plug and the hole adopt an interference fit, but Because it is a through hole, vibration occurs during the opening and closing of the mold, which can easily cause the pin to come out, damage the mold, and cause accidents and cost increases. [0003] The present invention is produced based on the above problems. 【Content of invention】 [0004] The object of the present invention is to propose an easy-maintenance jack pin fixing structure aiming at the deficiencies of the prior art. [0005] In order to solve the above-mentioned technica...
