Abstract
The utility model discloses a squeezing device of a mould, which comprises a squeezing pin (1) and a squeezing oil cylinder (3). The squeezing pin (1) is installed on the squeezing oil cylinder (3) and is sheathed with a squeezing pin bush (2). The fit clearance between the squeezing pin (1) and the squeezing pin bush (2) is less than or equal to 0.02mm. The utility model has the advantages that the squeezing device can provide the mould cavity with a high pressure to crush the porosity in the casting liquid and the air tightness of the products is improved.
Description
Technical field
The utility model relates to mould, is specifically related to a kind of pressurizing unit of mould.
Background technology
Mould is manufacturing important foundation equipment, and it is " a beyond challenge benefit amplifier ".Do not have high-caliber mould, also just do not have high-caliber industrial products, so Tool and Die Technology also becomes one of important symbol of weighing a national product manufacture level.The die-cast product that the mould of present how tame mould enterprise is produced can not satisfy client's product standard, and its reason is that the product pore is too much, poor air-tightness.
Summary of the invention
The purpose of this utility model is: provide a kind of extruding of mould tightly to put, give the die cavity high pressure by this pressurizing unit, pore in the crushing casting liquid, the air-tightness of raising product.
Technical solution of the present utility model is: this pressurizing unit is made up of squeeze pin, extrusion oil cylinder, and squeeze pin is installed on extrusion oil cylinder.
In the pressurizing unit of mould of the present utility model, the external extruding guide of squeeze pin.
In the pressurizing unit of mould of the present utility model, squeeze pin and extruding guide fit clearance≤0.02mm.
In the mould production process, aluminium liquid enters die cavity, when not solidifying fully for 300-400 ℃, inserts the squeeze pin cover in die cavity, squeeze pin is positioned at the extruding guide, starts extrusion oil cylinder, drives squeeze pin and travels forward, give die cavity 900Mpa high pressure,, press little the crushing of the pore in the aluminium liquid.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1 squeeze pin, 2 extruding guidees, 3 extrusion oil cylinders.
The specific embodiment
As shown in Figure 1, this pressurizing unit is made up of squeeze pin 1, extrusion oil cylinder 3, and squeeze pin 1 is installed on extrusion oil cylinder 3.
In the pressurizing unit of mould of the present utility model, squeeze pin 1 external extruding guide 2.
In the pressurizing unit of mould of the present utility model, squeeze pin 1 and extruding guide 2 fit clearances≤0.02mm.
In the mould production process, aluminium liquid enters die cavity, when not solidifying fully for 300-400 ℃, inserts squeeze pin cover 2 in die cavity, squeeze pin 1 is positioned at extruding guide 2, starts extrusion oil cylinder 3, drives squeeze pin 1 and travels forward, give die cavity 900Mpa high pressure,, press little the crushing of the pore in the aluminium liquid.
Claims (3)
1. the pressurizing unit of mould, it is characterized in that: this pressurizing unit is made up of squeeze pin (1), extrusion oil cylinder (3), goes up at extrusion oil cylinder (3) squeeze pin (1) is installed.
2. the pressurizing unit of mould according to claim 1 is characterized in that: the external extruding guide of squeeze pin (1) (2).
