Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings, and the aforementioned and other objects, features, aspects and advantages of the present invention will become more apparent, so that those skilled in the art can implement them with reference to the description. In the drawings, the shapes and dimensions may be exaggerated for clarity, and the same reference numerals will be used throughout to designate the same or like parts. In the following description, terms such as center, thickness, height, length, front, back, rear, left, right, top, bottom, upper, lower, etc. are based on the orientation or positional relationship shown in the drawings. In particular, "height" corresponds to the dimension from top to bottom, "width" corresponds to the dimension from left to right, and "depth" corresponds to the dimension from front to back. These relative terms are for convenience of description and are generally not ...

Abstract

The invention discloses a one-way ejection structure. The one-way ejection structure comprises a fixed die insert and an ejection structure body which penetrates through the fixed die insert. The ejection structure body comprises a push rod, a connecting shaft, a belleville spring, a shaft coupling and a spring stop plate, wherein the push rod runs through the fixed die insert; one end of the connecting shaft is connected with the push rod; the belleville spring is arranged on the surface of the connecting shaft in a sleeving manner; one end of the shaft coupling is connected with the belleville spring; the top end of the connecting shaft runs through the shaft coupling; and the spring stop plate is connected with the other end of the shaft coupling. The one-way ejection structure has thebeneficial effects of being simple in structure, greatly reducing the die space occupied by the ejection structure body, achieving an ejection effect and saving the die cost.

Description

technical field [0001] The invention relates to the field of high-pressure casting, and more specifically, the invention relates to a one-way ejection structure. Background technique [0002] In aluminum alloy die-casting, due to the excessive clamping force of the product on the side of the fixed mold, the ejection structure needs to be released on the side of the fixed mold to avoid uneven force and serious deformation of the product after the mold is opened, and even stay in the fixed mold, making it difficult to take out . The traditional fixed mold ejection structure is composed of multiple large parts and takes up more mold space, not to mention that it is difficult to layout when the mold space is insufficient. [0003] In order to solve the problem of difficult layout of the mold space, we optimized the ejection structure of the entire fixed mold and changed it to a one-way ejection structure. The spring force is directly applied to the push rod, and single ejection...
