Abstract
The utility model discloses an extrusion mechanism for controlling the porosity of a die cast mold core. The extrusion mechanism is characterized by comprising an oil cylinder I, an oil cylinder II, a slide block extruding mold core I, a slide block extruding mold core II and a slide block extruding mold core III, wherein the oil cylinder I and the oil cylinder II are arranged inside a slide block, an oil cylinder shaft of the oil cylinder I is connected with the slide block extruding mold core I, the slide block extruding mold core II and the slide block extruding mold core III are fixed on a slide block extruding mold core fixed plate, the slide block extruding mold core fixed plate is connected with a slide block extruding mold core fixed base plate through a connecting member, and the slide block extruding mold core fixed base plate is fixed on the oil cylinder shaft of the oil cylinder II. The extrusion mechanism for controlling the porosity of the die cast mold core has the advantages that the structure is compact, the occupied space is small, the material is saved, the casting percent of pass can be effectively improved, and the waste loss rate can be effectively reduced.
Description
Technical field
The utility model relates to a kind of pressing mechanism of controlling die casting core porosity.
Background technology
Oil sump is vitals on the automobile engine, material is ALSi9Cu3, and its appearance and size is 430mm * 310mm * 150mm, and large end face and side all need process, four cored hole place strict control inside die-casting part porosity＜=5% are arranged, the pressing mechanism of the core porosity of existing control oil sump, complex structure, the material of use is many, the space that takies is large, cause production cost high, economic benefit is low, can not satisfy production requirement.Therefore, should provide a kind of new technical scheme to address the above problem.
The utility model content
The purpose of this utility model is: for above-mentioned deficiency, provide the pressing mechanism of the control die casting core porosity of a kind of compact conformation, conserve space, saving material.
For achieving the above object, the technical solution adopted in the utility model is: a kind of pressing mechanism of controlling die casting core porosity, comprise the oil cylinder I, the oil cylinder II, slide block extruding core I, slide block extruding core II and slide block extruding core III, described oil cylinder I and oil cylinder II are located at slide block inside, the oil cylinder axle of described oil cylinder I is connected with slide block extruding core I, and both junctions are provided with joint, described slide block extruding core II and slide block extruding core III are fixed on the slide block extruding core fixing plate, described slide block extruding core fixing plate is connected with slide block extruding core fixed base plate by connector, described slide block extruding core fixed base plate is fixed on the oil cylinder axle of oil cylinder II, described oil cylinder I and oil cylinder II inside are equipped with piston, all be arranged with the axostylus axostyle cover on the oil cylinder axle of oil cylinder I and oil cylinder II, the end of oil cylinder I and oil cylinder II is equipped with the oil cylinder pressing plate, one side of oil cylinder pressing plate is provided with the oil cylinder protecgulum, oil cylinder I and oil cylinder II are provided with a plurality of oil outlets, and a side of the take-up housing body of fixing described slide block is provided with vent line joint and in-line joint.
Described connector is screw.
The both sides of described oil cylinder I and oil cylinder II are provided with a plurality of cooling points.
Described axostylus axostyle cover is copper axostylus axostyle cover.
A kind of pressing mechanism of controlling die casting core porosity of the utility model all is built in two oil cylinders in the slide block, is conducive to take full advantage of the space of slide block and take-up housing.Slide block is pushed core I, II and slide block extruding core III prop up die casting in the die cavity, back and oil cylinder I, II link, the packing stage of finishing after filling type and supercharging at die casting machine carries out secondary extrusion, plays the effect of by force feeding, to eliminate shrinkage cavity and loose; The air that simultaneously this position is involved in compresses by force, even drives out of from molten metal, and with the minimizing pore, thereby it is finer and close that die casting is organized, and improves casting qualified rate, the loss of reducing the number of rejects and seconds.
The utility model has the advantages that: compact conformation, take up room little, save material, energy Effective Raise casting qualified rate, the loss late of reducing the number of rejects and seconds.
