The core pulling device is simple in structure; the die casting mold core pulling device adopts the two oil cylinders, and two mold blocks for placing the oil cylinders are arranged on the movable mold, so that the mounting height of the oil cylinders is lowered; and therefore, the interference with a safety door cannot happen when the core pulling travel is longer.
Description
Technical field
The utility model belongs to the die casting field, relates in particular to a kind of core-pulling device.
Background technology
Core-pulling device is a kind of device that moving core can be extracted out and resetted, and the obstruction die casting along the moulding section that takes out perpendicular to the die joint direction, all must break away from die casting before die sinking or in the die sinking process from mould.In the mould structure, make the moulding section of this obstruction die casting demoulding, before the die sinking action is finished, break away from the mechanism of die casting, be called core-pulling device.Core-pulling device is the important part of aluminum alloy die-casting die, stroke is long or when having special action to require owing to loose core, have the situation that takes place with equipment action interference, or needing the core-pulling device course of action that the compound of a plurality of actions arranged, this has just proposed specific (special) requirements to the core-pulling device result of die casting.
Chinese patent Granted publication number: CN201907183U, Granted publication day: on 07 27th, 2011, a kind of core-pulling device is disclosed, the pull bar that this core-pulling device includes template, oil cylinder and links with the oil cylinder output, described template is provided with storage tank, oil cylinder is installed in storage tank and is constituted the guide rail guide groove with the storage tank cell wall and cooperates, and fixes with the other end of oil cylinder output interlock end and the die on the outer mold on the pull bar, and the core rod on oil cylinder outer wall and the outer mold is fixed.The core-pulling device that this utility model proposes has the following disadvantages: vertical with the die casting equipment safety door when the position of core-pulling device, and oil cylinder and safety door can take place and interfere when longer in the stroke of loosing core, situation that can not the closed safe door during work.
The utility model content
The utility model is in order to overcome the deficiencies in the prior art part, a kind of core-pulling device to be provided, and when the stroke of loosing core is longer, the situation with the safety door interference can not take place.
To achieve these goals, the utility model is by the following technical solutions:
A kind of core-pulling device, comprise cover half, dynamic model, ejecting mechanism, fixed head and be located at core-pulling device on the dynamic model, described core-pulling device comprises slide block core, take-up housing and oil cylinder, described slide block core is fixedlyed connected with take-up housing, described oil cylinder number is two, described dynamic model be provided with two with suitable framed of described oil cylinder, described oil cylinder be fixed at described framed in.The die casting core-pulling device that the utility model proposes, its oil cylinder number is two, and oil cylinder is fixed in dynamic model framed, when the oil cylinder of this core-pulling device is installed than prior art core-pulling device oil cylinder when mounted, the setting height(from bottom) of oil cylinder reduces, thereby core-pulling device can not take place and the safety door interference when the stroke of loosing core is longer.
As preferably, described slide block core and take-up housing are fixed together by screw.In this preferred version, the fixed form of slide block core and take-up housing adopts screw to fix, like this situation about can not become flexible between slide block core and the take-up housing.
As preferably, the piston crown of described oil cylinder is fixedlyed connected with fixed head.In this preferred version, the piston crown of oil cylinder is fixedlyed connected with fixed head, and when oil cylinder was oil-filled, the piston of oil cylinder stretched out, thereby promotes the fixed head motion; When the oil cylinder draining, the piston of oil cylinder is regained, thereby drives returning of fixed head.
As preferably, be provided with a shaft coupling at described take-up housing, be fixedly connected with connecting axle at described shaft coupling, the other end of connecting axle is fixedlyed connected with described fixed head.In this preferred version, at take-up housing a shaft coupling is set, shaft coupling is fixedlyed connected with an end of connecting axle, the other end of connecting axle is fixedlyed connected with fixed head, when oil cylinder during oil-filled or draining, the piston of oil cylinder stretches out or regains the release that drives fixed head or return, and moves with the fixedly connected connecting axle of fixed head thereby drive, and connecting axle moves together by the shaft coupling take-up housing.
As preferably, be respectively equipped with a hanging feet at the medial extremity of described two oil cylinders.In this preferred version, be respectively arranged with a hanging feet at the medial extremity of two oil cylinders, oil cylinder be fixed at framed in the time, hanging feet plays the effect of fixed oil cylinder, it is framed to avoid oil cylinder to detach.
Compared with prior art, the utlity model has following beneficial effect: simple in structure, the oil cylinder of the core-pulling device of this die casting adopts two, and dynamic model is provided with two modules that can place oil cylinder, such project organization makes the installation height step-down of oil cylinder, when the stroke of loosing core is longer, the situation with the safety door interference can not take place like this.
Description of drawings
Fig. 1 is a kind of internal structure schematic diagram of the present utility model.
Among the figure, 1-oil cylinder, 2-take-up housing, 3-slide block core, 4-shaft coupling, 5-connecting axle, 6-hanging feet.
The specific embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
A kind of core-pulling device as shown in Figure 1, comprise cover half, dynamic model, ejecting mechanism, fixed head and be located at core-pulling device on the dynamic model, described core-pulling device comprises slide block core 3, take-up housing 2 and oil cylinder 1, described slide block core 3 is fixedlyed connected with take-up housing 2, described oil cylinder 1 number is two, described dynamic model be provided with two with suitable framed of described oil cylinder 1, described oil cylinder 1 be fixed at described framed in.The piston crown of described oil cylinder 1 is fixedlyed connected with fixed head.Be provided with a shaft coupling 4 at described take-up housing 2, be fixedly connected with connecting axle 5 at described shaft coupling 4, the other end of connecting axle 5 is fixedlyed connected with described fixed head.
Preferably, described slide block core 3 and take-up housing 2 are fixed together by screw.Preferably, the medial extremity at described two oil cylinders 1 is respectively equipped with a hanging feet 6.
Operation principle of the present utility model is: oil-filled at oil cylinder 1, the piston of oil cylinder 1 stretches out, and promotes the fixed head motion, drives the connecting axle 5 that is fixed on the fixed head simultaneously and does and lead to motion; Connecting axle 5 drives take-up housing 2 and does the action of withdrawing from product by shaft coupling 4.When oil cylinder 1 draining, the piston of oil cylinder 1 is return, and pulling fixed head motion drives the connecting axle 5 that is fixed on the fixed head simultaneously and does and lead to motion; Connecting axle 5 is by shaft coupling 4, and band take-up housing 2 is done the action that die cavity resets.A kind of die casting core-pulling device that the utility model proposes passes through above-mentioned cylinder action, thereby finishes the working cycles of core-pulling device.
