Description

Die casting machine tup lubricating mechanism

Technical Field

The utility model relates to a die-casting technical field, concretely relates to die casting machine tup lubricating mechanism.

Background

Die casting is a metal casting process and is characterized in that a die cavity is used for applying high pressure to molten metal. The mold is typically machined from a stronger alloy, a process somewhat similar to injection molding. The inner wall sliding contact of current large-scale die casting machine tup and material pipe if lubricated bad, can lead to tup and material pipe wearing and tearing, and the tup wearing and tearing back, need change the tup, this can lead to the production to be interrupted. During production, restarting if production is interrupted can result in increased rejects and decreased die life. Therefore, a lubricating operation of the hammer head is required.

The existing hammer head lubricating modes comprise two modes, one mode is that granular oil is thrown into a feeding pipe from a material pouring port for lubrication, the cost is low, the lubricating effect is good, but the granular oil can pollute molten metal while lubricating the hammer head; the other method is to spray plunger oil at the rear end of the hammer head, so that the metal liquid is not polluted; however, the front section of the hammer head cannot be lubricated, so that the hammer head is easy to clamp, and the production is unstable; most can flow along the tup and fall below the material pipe when plunger oil sprays, lead to near the serious dirty product percent of pass that influences of material pouring mouth.

Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1-4, the utility model discloses a die casting machine tup 31 lubricating mechanism, including material pipe 10 and tup 31, tup 31 is located material pipe 10, and tup 31 is located the one end of injection pole, and under the effect of injection pole 30, tup 31 removes in order to push away the material in material pipe 10.

The material pipe 10 comprises a lubricating pipe body 20, an oil inlet 21 and an oil outlet 22 are formed in the lubricating pipe body 20, a lubricating cavity is formed between the lubricating pipe body 20 and the hammer head 31 in a matched mode, and the oil inlet 21 and the oil outlet 22 are communicated with the lubricating cavity.

The working principle of the utility model is that when the injection rod 30 returns to the lubricating pipe body 20, oil is added from the oil inlet 21, so that plunger oil is provided in the lubricating cavity, the plunger oil can lubricate the hammer head 31, and the plunger oil in the lubricating cavity is discharged from the oil outlet 22; after the hammer 31 is lubricated, the injection rod 30 drives the hammer 31 to move forward to push materials.
