Ejection structure for mold machining

Abstract

The invention discloses an ejection structure for mold machining, and relates to the technical field of mold machining. The ejection structure comprises a base, a lower fixed mold and an upper moving mold, wherein the lower fixed mold is fixedly arranged on the upper surface of the base; the upper moving mold is slidably connected to the upper surface of the base and located above the lower fixed mold; and a storage fixed mold, a closing mechanism, an ejection mechanism and a heat dissipation mechanism are fixedly arranged in the lower fixed mold. By arranging the closing mechanism, two lead screws are driven by a double-shaft motor to rotate, two closing plates are promoted to move oppositely, and the through holes are promoted to be gradually opened or closed, so that the sealing performance of the storage fixed mold in the mold machining process is guaranteed, the problem that the machining precision and the machining shaping effect of a to-be-machined mold are affected due to fact that opening needs to be arranged in the fixed mold in an existing ejection mode is avoided, and the machining precision and the machining shaping effect of the to-be-machined mold are effectively improved.

Description

technical field [0001] The invention relates to the technical field of mold processing, in particular to a jacking structure for mold processing. Background technique [0002] Mold processing refers to the processing of forming and billet tools, and also includes shearing dies and die-cutting dies. Usually, the mold consists of two parts, the upper mold and the lower mold. The steel plate is placed between the upper and lower molds, and the material is formed under the action of the press. When the press is opened, the workpiece determined by the shape of the mold will be obtained or the corresponding waste will be removed, ranging from electronic connectors to large The workpieces of automobile dashboards can be molded. Progressive die refers to a set of molds that can automatically move the workpiece from one station to another, and obtain formed parts at the last station. Mold processing technology includes: cutting die, punching die, composite die, extrusion die, four...

AI Technical Summary

Problems solved by technology

[0003] 1. In the prior art, after the mold processing is completed, the parts in the fixed mold are usually removed by manual tools, but the instability of manual operation makes it easy to leave scars on the surface of the workpiece during the removal process, and it is more laborious

[0004] 2. In the prior art, after the mold processing is completed, the temperature of the mold body is too high, so that the progress of the ejection work of the mold is hindered to a certain extent, and the progress of the mold processing is affected
