Magnesium alloy part tooth-pushing mechanism and mold

Abstract

The invention discloses a magnesium alloy part tooth-pushing mechanism. The magnesium alloy part tooth-pushing mechanism comprises a positioning block, a tooth cutter, a self-return linear slide mechanism and a jacking mechanism, wherein a positioning hole and a tooth cutter through hole are formed in the positioning block; the positioning hole communicates with the inner cavity of the tooth cutter through hole; the tooth cutter which is adaptive to the tooth cutter through hole is movably arranged in the tooth cutter through hole in a penetrating mode; the tooth cutter is arranged in a slidedirection of the self-return linear slide mechanism; the tail end of the tooth cutter is connected to a slide part of the self-return linear slide mechanism; the jacking mechanism and the tooth cutterare separately positioned at the two ends of the self-return linear slide mechanism; and the jacking mechanism jacks the slide part, so that the tooth cutter is pushed to slide across the positioninghole. The magnesium alloy part tooth-pushing mechanism disclosed by the invention, the tooth pushing structure acts once for processing out a tooth-shaped structure on a workpiece conveniently and quickly; and the tooth pushing mechanism is easily integrated onto a mold of a trimming and material-removing head slag ladle, so that processes are favorably saved, production efficiency is improved, and cost is reduced.

Description

technical field [0001] The invention belongs to the field of punching dies, and in particular relates to a gear pushing mechanism and a die for magnesium alloy parts. Background technique [0002] Die-casting technology is an important technology for the production of magnesium alloy light metal workpieces. It has the advantages of one-time rapid prototyping, less workpiece machining allowance, and high recycling rate of raw materials. In order to meet the requirements of complex product structure, die-casting equipment and technology have been continuously improved, and various workpieces with complex shapes can be formed with high quality. After the workpiece is formed, the process of trimming and removing the head and slag bag is carried out. This process is generally completed on the punching die. According to the product design, subsequent machining may be required to complete structures that cannot be processed by the front-end process. For example, there are pillars...

Problems solved by technology

According to the existing technology, the workpiece is formed by die-casting first, then the edge is trimmed to remove the head slag bag, and then the teeth are milled out one by one on the column by machining, which is time-consuming

Due to the large size of the product, in the process of turnover and pick-and-place, each beat takes a long time. At the same time, the equipment used in the milling process is relatively large and expensive.

Adding a milling process in this way will lead to a greatly extended production cycle, low production efficiency, a substantial increase in the cost of a single product, low product profit margins, and weak market competitiveness.
