Abstract

The utility model provides an improved sand-core injection machine with convenient sand-loading and safe operating, which comprises a framework, a left die, a right die, a closing cylinder, a sand hopper, a sand-shooting nozzle, a sand-shooting cylinder, a slide block and a cross sliding type cylinder, wherein at least one of the left die and the right die is movably arranged on the framework through the closing cylinder, a sand outlet which can be opened and closed is arranged on the lower portion of the sand hopper, the slide block is arranged on the framework in a mode of transversely moving, the sand-shooting nozzle is arranged on the slide block through the sand-shooting cylinder in a lifting mode, the sand outlet of the sand-shooting nozzle is arranged under the die-closing position of the left die and the right die, and the bottom of the sand-shooting nozzle is connected with the air source of compression air. The machine is used for sand core injection molding.

Description

A kind of improved core injector

Technical field

The utility model relates to a kind of improved core injector, and it belongs to metal casting technique equipment.

Background technology

Parts such as existing copper alloy, the aluminium alloy general mode that adopts metal outer mold and core to combine of when casting is cast, and the core injector is exactly that the sand material is sintered into the core with ad hoc structure after by injection moulding.Known core injector generally comprises frame, lead, left mould, right mould, sand hopper, penetrates Sha Zui, matched moulds cylinder and penetrate the sand cylinder, described left mould and right mould can be located on the frame by lead respectively with relatively moving, sand hopper is located on the frame, the sand export of sand hopper with penetrate the sand mouth and be connected by conveyance conduit, and conveyance conduit also is connected with compressed air hose, and the matched moulds cylinder is located between frame and left mould and the right mould.In the time of work, the matched moulds cylinder drives left mould and right mould matched moulds, penetrating the sand mouth moves down in penetrating the sand station in the effect of penetrating the sand cylinder, sand material in the sand hopper is transported under compressed-air actuated ejector action in the die cavity between left mould and the right mould, and the core behind the injection molding generally also carries out sinter molding by the heater of being located on left mould and the right mould to core.The disclosed core shooter of Chinese patent CN2587615Y of bulletin promptly disclosed this kind structure as on November 26th, 2003, but traditional this kind core shooter has following deficiency:

1, the position of sand hopper is higher, and equipment occupation space is big, and operating personnel adorn sand inconvenience;

2,, penetrate the sand material that joint splashes between sand mouth and the mould there is potential safety hazard in operating personnel when the die cavity of mould is penetrated sand;

The utility model content

The purpose of this utility model provides a kind of improved core injector of adorning sand convenience, handling safety.

The technical scheme that the utility model adopted is such: a kind of improved core injector, comprise frame and be located at left mould on the frame, right mould, the matched moulds cylinder, sand hopper, penetrate Sha Zui, penetrate the sand cylinder, slide block, traversing cylinder, at least be located on the frame movably by the matched moulds cylinder for one in described left mould and the right mould, the sand hopper below is provided with able to turn on or off sand export, slide block can laterally be located on the frame by traversing cylinder movably, penetrating the sand mouth liftably is located on the slide block by penetrating the sand cylinder, the sand export of penetrating the sand mouth is positioned at the below, position behind left mould and the right mould matched moulds, penetrates sand gonys portion and is connected with compressed air gas source.

Above-mentioned improved core injector is positioned at the frame of penetrating both sides, sand mouth front and back and is provided with protective plate.

Above-mentioned improved core injector, described sand hopper are located on the frame of position, side of left mould or right mould.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are:

1, penetrate sand owing to penetrate Sha Zui from the following direction die cavity of mould, the sand material that sprays when frame or the protective plate on it can prevent to penetrate sand like this is splashed on people's the body, guarantees operator safety;

2, the sand hopper installation site is lower, convenient dress sand;

3, the mode that the direction die cavity is penetrated sand under the mould makes more compact structure, reduces to take up room;

Description of drawings

Fig. 1 is the structural representation of embodiment;

Fig. 2 penetrates the sand structural representation for embodiment;

The specific embodiment

With reference to figure 1 and Fig. 2, embodiment discloses a kind of improved core injector, comprise frame 1, left side mould 2, right mould 3, matched moulds cylinder 4, penetrate sand mouth 5, sand hopper 6, penetrate sand cylinder 7, traversing cylinder 8, slide block 9, described frame 1 is used for supporting, fixing aforementioned each part, left side mould 2 is fixed on the frame 1, right mould 3 is located on the frame 1 movably by matched moulds cylinder 4, certain described left mould 2 also can be located on the frame 1 movably by another one matched moulds cylinder, and right mould 3 also can be directly fixed on the frame 1 when left mould 2 is provided with the matched moulds cylinder, perhaps left mould 2 all is provided with the matched moulds cylinder with right mould 3, it can realize the purpose of this utility model, sand hopper 6 is located at and is positioned on the frame 1 near the left mould 2, slide block 9 can laterally be located on the frame 1 movably by traversing cylinder 8, penetrating sand mouth 5 liftably is located on the slide block 9 by penetrating sand cylinder 7, and be arranged to penetrating and rise under the effect of sand cylinder 7 when penetrating the sand station when penetrating sand mouth 5, the sand export of penetrating sand mouth 5 just be positioned at matched moulds after the corresponding position of sand inlet of die cavity so that the sand material is injected into die cavity, thereby at the non-sand state of penetrating, the described sand mouth 5 of penetrating can be removed from the below of mould so that change left mould 2 and right mould 3, the below of described sand hopper 6 is provided with able to turn on or off sand export can be to penetrating sand mouth 5 heap sand material when penetrating sand mouth 5 and move to sand hopper 6 belows with box lunch, the bottom of penetrating sand mouth 5 is connected with compressed air hose by valve 51, thereby under compressed-air actuated effect, the sand material of penetrating in the sand mouth 5 is transported in the die cavity of mould, be positioned on the frame 1 in addition and penetrate sand mouth 5 front and back two side positions and be provided with protective plate, take place to prevent when penetrating sand the splash incident that causes hurting sb.'s feelings of sand material.
