Problems solved by technology
However, in the existing micro-extrusion molding, it is difficult to release the mold due to the small size of the extrusion.
The size of the extruded parts formed by micro-forming is small and the strength is also low. Using the general ejection method to pick up the parts is easy to cause damage and deformation to the formed parts

Embodiment Construction
[0016] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, characteristics and effects of the present invention.
[0017] In order to easily take out the extruded parts, a double Hough conical concave die structure is designed in the microforming die. This is mainly because in the extrusion process, the lower Huff conical die can effectively solve the problem of the difficulty of the tooth-shaped parts from the working belt of the die. On the other hand, during the extrusion process, the excess billet and bottom The extruded parts are still connected together. Because the size of the micro-formed parts is small, generally less than 1mm in diameter, and the strength of the parts is also low, so in the process of removing the extruded parts, It is easy to deform the micro-formed parts during demoulding due to the friction between the bl...

Abstract
The invention discloses a micro-extrusion mold suitable for the micro-molding product manufacture field; the technical scheme adopts mold structure design with a bipyramid half structure, which comprises an outer mold sleeve, a lower mold base, a support plate, a push pin, an extrusion gasket, a lower half pyramid female mold, an upper mold base, a micro forward extrusion limiting plate, a micro forward extrusion rod, an extrusion rod guide block, an upper half pyramid female mold, an extrusion pad, and an ejection block. The lower half pyramid female mold is tightly connected with the lower half female mold base through a pyramid surface, and the upper half pyramid female mold is tightly connected with the upper mold base through a pyramid surface. Extrusion molding is mainly realized by the downward motion of the extrusion rod guide block at the upper part of the mold to apply extrusion force to blank materials by the extrusion rod, and thus the blank materials move downwards to enter a cavity of the female mold so as to obtain an extruded member. The invention is suitable for micro-extrusion molding technology for extruding and processing members with a dimension less than 1 mm, and the extruded member is convenient for taking out.
Description
technical field [0001] The invention relates to the field of extrusion molding die, in particular to a micro extrusion die. Background technique [0002] With the rapid development of the electronic industry and precision machinery, the miniaturization of products has become one of the trends in the industry. Micro-forming technology is widely accepted by countries around the world because it can meet the needs of the miniaturization industry for large quantities, high efficiency, high precision, and low cost. of great attention. However, in the conventional micro-extrusion molding, demolding is difficult due to the small size of the extruded parts. The micro-formed extruded parts are smaller in size and lower in strength, and the general ejection method is easy to cause damage and deformation to the formed parts. [0003] Therefore, those skilled in the art are devoted to developing a micro-extrusion die with a double Hough conical concave die structure that can easily ta...
