Equipment for punching ejector plate of injection mold

Abstract

The invention discloses equipment for punching an ejector plate of an injection mold, and relates to the technical field of punching of ejector plates. The equipment for punching the ejector plate of the injection mold comprises a drilling machine, the outer wall of the drilling machine is fixedly connected with a fixing cylinder, the lower side of the fixing cylinder is provided with an injection pipe, the outer wall of the drilling machine is fixedly connected with a liquid storage tank, the outer wall of the liquid storage tank is fixedly connected with the inner wall of the fixing cylinder, and the interior of a feeding box and a feeding port are communicated with the interior of the liquid storage tank; and a cover plate is hinged to the upper side of the feeding box. According to the equipment for punching the ejector plate of the injection mold, gas in a gas storage box is expanded, a sliding block moves in the fixing box due to vibration, so that a first connecting pipe communicates with a second connecting pipe; and when a rotating rod of a drilling machine is pulled out of the ejector plate, the sliding block is influenced by a first spring to reset due to the fact that vibration is reduced, communication between the second connecting pipe and the first connecting pipe is blocked, the effect that cutting fluid can be sprayed only during drilling is achieved, and waste is avoided.

Description

technical field [0001] The invention relates to the technical field of punching pin plates, in particular to equipment for punching pin plates of injection molds. Background technique [0002] When demoulding the injection mold, it is necessary to use ejector pins to assist demoulding. Since the ejector pin installation needs to be adjusted to the specific target, it is necessary to pre-drill holes on the ejector plate to facilitate the setting of the ejector plate. When drilling the ejector plate In the work, it is necessary to use a drilling machine to drill holes, but because the general drilling machine is not equipped with the overall cutting fluid injection equipment, it is necessary to manually spray the cutting fluid to the drill bit when drilling, which is very difficult. Therefore, there is a need for a device that can be easily installed on the drilling machine to complete the spraying of cutting fluid and reduce the waste of manpower. Contents of the invention ...
