Die-casting quantitative feeding system

Abstract

The invention relates to the technical field of quantitative feeding systems, and discloses a die-casting quantitative feeding system which includes a boiler and a material drawing box. The inner wallof the boiler is fixedly connected with a crucible, a motor dragging system is fixedly connected to one side of the top of the boiler, and the top of the material drawing box is fixedly connected with a material drawing box cover; and a discharge pipe is fixedly connected to one side of the top of the material drawing box cover, the bottom end of the discharge pipe penetrates through the materialdrawing box cover and extends to the lower part of the inner part of the material drawing box. According to the die-casting quantitative feeding system, descending of the material drawing box is controlled by the motor dragging system, so that the liquid surface pressure difference is generated, melt in the crucible is poured back into the material drawing box, then air intake supercharging is carried out by an air intake pipe to enable air pressure difference to be generated between the material drawing box and the outside world, the melt in the material drawing box is pressed out, by cooperating with a sliding column, a stainless steel float, an induction block and an induction switch control system, a new cycle is started after the melt is pressed out of the quantitative value, the purpose of quantitative feeding as set is achieved, and quantitative feeding in the process of die casting is realized.

Description

technical field [0001] The invention relates to the technical field of quantitative feeding systems, in particular to a quantitative feeding system for die-casting. Background technique [0002] Die casting is a metal casting process characterized by the application of high pressure to molten metal using the cavity of a mold. Molds are usually machined from stronger alloys, a process somewhat similar to injection molding. Most die castings are ferrous, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Depending on the type of die casting, a cold chamber die casting machine or a hot chamber die casting machine is used. The cost of casting equipment and molds is high, so the die casting process is generally only used for mass production of a large number of products. Manufacturing die-cast parts is relatively easy, generally requiring only four major steps with low incremental cost per item. Die casting is especially suitable for m...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a quantitative feeding system for die-casting, which solves the problem that most of the existing die-casting feeding systems are directly pumped through the pumping device, which requires manual control of the feed amount and requires operation.
