Abstract
The utility model relates to an ejection device for a die casting machine. The ejection device comprises a head plate, wherein an ejection oil cylinder is arranged in the head plate, and comprises a piston rod, a cylinder body and a flange, and the cylinder body is embedded into the head plate; the flange and the cylinder body are connected to form a chamber, and the piston rod is positioned in the chamber; the end face of the flange flushes with the end face of the head plate, and a cooling water jacket is arranged at the outer side of the cylinder body; an oil pipe is arranged in the head plate and is communicated with the chamber. The ejection oil cylinder is arranged in the head plate, and the head plate is close to a sprue gate, so the temperature is higher; the ejection oil cylinder is arranged in the head plate, so the temperature of the ejection oil cylinder is also high; the cooling water jacket with cooling water is arranged at the outer side of the ejection oil cylinder in order to prevent that hydraulic oil in the ejection oil cylinder is aged and deteriorated; the head plate is cast by ductile iron, and the direct contact between the head plate and the hydraulic oil is not good, therefore, the oil pipe for oil to pass is arranged in the head plate. The ejection device provided by the utility model has the characteristics of simple and reasonable structure, flexible operation and low production cost.
Description
Technical field
The utility model relates to the liftout attachment of a kind of die casting machine, particularly a kind of die casting machine.
Background technology
Cold-chamber die casting machine be by the direct injection progressive die of molten metal tool by supercharging, cooling and a kind of Die Casting equipment of moulding.Common Design of Dies is the one side at cover half cavity design, and core designs the one side at dynamic model, after die casting completes, when foundry goods is cooling, because there is contraction, to the enclasping force of core just much larger than the bulging power to die cavity, when die sinking, workpiece just and dynamic model connect together, with the action of dynamic model, separate with cover half, by the liftout oil cylinder being arranged on dynamic model, workpiece is pushed from the core of dynamic model afterwards, thereby complete a die casting actuation cycle.
But for some more special workpiece, we cannot be core designs in dynamic model one side, at this time workpiece has just been stayed cover half one side, also just must on cover half, design Lifting Device accordingly.
Chinese patent literature CN201988704U discloses a kind of forming mechanism for reverse drawing die structure of die casting on 09 28th, 2011, comprise die casting machine, mould and manipulator and manipulator electrical control cubicles, manipulator electrical control cubicles is controlled manipulator running, on mould, be provided with knock pin, die casting machine is connected with a liftout plate by a pull bar, and liftout plate is connected with a return plate; Slideway is set on mould, on slideway, is provided with a moulding of falling withdrawing pattern and inserts; Return plate is inserted and is connected with the moulding of falling withdrawing pattern by a connecting rod.Manipulator is connected with a source of the gas, and source of the gas is controlled by manipulator electrical control cubicles, and one end of a blowning installation connects source of the gas, and the other end is connected on mould, can aim at slideway and blow.This shaping mechanism complex structure, operates also cumbersome.
Utility model content
The purpose of this utility model aims to provide the liftout attachment of a kind of simple and reasonable, flexible operation, die casting machine that cost of manufacture is low, to overcome weak point of the prior art.
Liftout attachment by a kind of die casting machine of this object design, comprises a plate, and its architectural feature is in a plate, to be provided with liftout oil cylinder.
Further, described liftout oil cylinder comprises piston rod, cylinder body and flange, and cylinder body embeds a plate, and flange and cylinder body join and surround chamber, and piston rod is arranged in chamber.
Further, the end face of described flange is concordant with the end face of a plate.
Further, the arranged outside of described cylinder body has cooling jacket.
Further, in described plate, be provided with oil pipe.
Further, described oil pipe communicates with chamber.
The utility model arranges liftout oil cylinder in a plate, because a plate approaches sprue gate, temperature is higher, and liftout oil cylinder is arranged on a plate the inside, the temperature of liftout oil cylinder also can be very high, in order to prevent the hydraulic oil aged deterioration in liftout oil cylinder, in the arranged outside of ejection cylinder, there is the cooling jacket that is connected with cooling water; Because a plate is to adopt spheroidal graphite cast-iron casting to form, discount plate directly contacts also not so good with hydraulic oil, therefore, the oil pipe of logical oily use is housed in a plate.
Adopt after above-mentioned technical scheme, can not necessarily Lifting Device will be arranged on dynamic model, so can simplify Design of Dies, improve the process rationality of die casting.
The utlity model has simple and reasonable, flexible operation, feature that cost of manufacture is low; After being applicable to die casting and completing, workpiece is stayed the situation in cover half.
Accompanying drawing explanation
Fig. 1 is the biopsy cavity marker devices structural representation of the utility model one embodiment.
Fig. 2 is that A-A in Fig. 1 is to dissecing enlarged diagram.
Fig. 3 is the biopsy cavity marker devices enlarged diagram of cylinder body.
In figure: 1 is liftout piston rod, 2 is liftout cylinder block, and 3 is cylinder mouth flange, and 4 is a plate, and 5 is oil pipe, and a is cooling water inlet, and b is coolant outlet.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Referring to Fig. 1-Fig. 3, the liftout attachment of this die casting machine, comprises a plate 4, is provided with liftout oil cylinder in a plate 4.
In the present embodiment, liftout oil cylinder comprises piston rod 1, cylinder body 2 and flange 3, and cylinder body 2 embeds a plate 4, and flange 3 joins and surrounds chamber with cylinder body 2, and piston rod 1 is arranged in chamber.
The end face of flange 3 is concordant with the end face of a plate 4, thereby does not affect the existing capability of a plate 4.
The arranged outside of cylinder body 2 has cooling jacket.In plate 4, be provided with oil pipe 5.Oil pipe 5 communicates with chamber.
Wherein, the cooling water inlet a of cooling jacket is than the more close oil pipe 5 of coolant outlet b.
After die casting completes, start liftout oil cylinder, by being contained in piston rod 1 action of the ejection cylinder in a plate of die casting machine, the workpiece being stuck in the cover half die cavity of a plate is ejected.
