A kind of equipment for punching holes in ejector plate of injection mold

Abstract

The invention discloses a device for punching a thimble plate of an injection mold, and relates to the technical field of punching a thimble plate. The equipment for punching the ejector plate of the injection mold includes a fixed cylinder fixedly connected to the outer wall of the drilling machine, an injection pipe is arranged on the lower side of the fixed cylinder, a liquid storage tank is fixedly connected to the outer wall of the drilling machine, and the storage tank is fixedly connected to the outer wall of the drilling machine. The outer wall of the liquid tank is fixedly connected with the inner wall of the fixed cylinder, the inside of the feed box is communicated with the feed port and the inside of the liquid storage tank, and a cover plate is hinged on the upper side of the feed box. In this injection mold ejector plate drilling equipment, the gas inside the gas storage box expands, and the slider moves in the fixed box due to vibration, so that the first connecting pipe and the second connecting pipe are connected, and the drilling machine rotates When the rod is pulled out of the thimble plate, the slider will reset under the influence of the first spring due to the reduced vibration, blocking the communication between the second connecting pipe and the first connecting pipe, so that the cutting fluid can be sprayed only when drilling effect and avoid waste.

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 ...
