Description
Technical field
The utility model relates to Casting Equipment field, is specifically related to a kind of cold core machine.
Background technology
Cold process coremaking has that core sclerosis is fast, productivity ratio is high, core geomery and surface accuracy advantages of higher and be widely used, and cold process coremaking equipment used is cold core machine.Gaza's device of tradition cold core machine is that a sand hopper be fixed in frame is formed, because sand has stickiness (sand is a kind of emplastic containing silica), add sand in sand process to be easily bonded on the inwall of sand hopper, the discharging opening of sand hopper also easily blocks the outlet of sand hopper because of the bonding between sand.Meanwhile, when the sand entrance penetrating sand device is separated with the outlet of sand hopper, because the outlet of sand hopper is without any blocking, easily sand is leaked.In addition existing mould generally will note sand mouth arrange comparatively large, penetrate sand device note sand to meet in mould, note sand mouth size is large, and air-tightness is bad, and the inlet place of the rear mold of note sand has remaining space, needs artificial back-up sand again, increases operation.
Utility model content
The purpose of this utility model is just to provide a kind of cold core machine, and it can effectively solve the problem, and avoids sand to be attached on the inwall of sand hopper.
For achieving the above object, the utility model is implemented by the following technical solutions:
A kind of cold core machine, it is characterized in that: comprise frame, upper rack is provided with sanding device and penetrates sand device, sanding device comprises the sand hopper floating and be fixed in frame, and sand hopper is connected with its vibrating mechanism carrying out vibrating of driving.
Further scheme is: the bottom discharge mouth place of sand hopper is provided with flashboard, and flashboard is connected with governor motion, and governor motion regulates flashboard to carry out closing or opening to the discharging opening of sand hopper.Frame is provided with the feet that vertical shape is arranged, feet is that screw rod is formed, and the shaft of screw rod is arranged with Compress Spring, and sand hopper is fixedly mounted on feet by pilot hole that it is offered and nut, and the aperture of pilot hole is greater than the diameter of screw rod.The bottom penetrating sand device is arranged penetrates Sha Zui, and penetrating sand mouth is an intubate formation extended downwards.The bottom penetrating sand device is also provided with the lifting mechanism of plunger tip plate in lifting, lifting mechanism comprises two vertical shapes jig arm positioned opposite and cylinder, the L shape of arranging in opposite directions is arranged in the lower end of two jig arm, the middle part of two jig arm with penetrate sand device and be articulated and connected by the first jointed shaft, the upper end of two jig arm forms respectively by the piston rod of the second jointed shaft and cylinder and cylinder body and is articulated and connected, and first and second jointed shaft is parallel to each other and arranges all in the horizontal direction.
In technique scheme, be fixed in frame by sand hopper is floated, like this when sand hopper correlation sand device adds sand, order about sand hopper by vibrating mechanism and vibrate, make to be bonded in sand on sand hopper inwall and also can drop down onto and penetrate in sand device.

Detailed description of the invention
In order to make the purpose of this utility model and advantage clearly understand, below in conjunction with embodiment, the utility model is specifically described.Should be appreciated that following word only in order to describe one or more concrete embodiments of the present utility model, considered critical is not carried out to the protection domain that the utility model is specifically asked.
The technical scheme that the utility model is taked as shown in Figure 1, 2, a kind of cold core machine, comprises frame 10, and frame 10 top is provided with sanding device and penetrates sand device, sanding device comprises the sand hopper 11 floating and be fixed in frame 10, and sand hopper 11 is connected with its vibrating mechanism 111 carrying out vibrating of driving.Frame 10 is also provided with mould (core box), upper plunger tip parts 18, lower plunger tip parts 14 and blowning installation, upper plunger tip parts comprise plunger tip plate, lower plunger tip parts comprise lower plunger tip plate, mould is made up of left and right side form 13, upper plunger tip plate, lower plunger tip plate, left and right side form 13, upper plunger tip parts 18, lower plunger tip parts 14 are connected with its driving mechanism (being made up of cylinder or hydraulic cylinder) carrying out movement of driving respectively, and mould, blowning installation 15 and miscellaneous part are specifically joined and can be implemented according to traditional cold core machine.In technique scheme, be fixed in frame 10 by sand hopper 11 is floated, like this when sand hopper 11 correlation sand device adds sand, order about sand hopper 11 by vibrating mechanism 111 and vibrate, make to be bonded in sand on sand hopper 11 inwall and also can drop down onto and penetrate in sand device.Vibrating mechanism 111 can adopt general vibrator to form.Concrete scheme is: frame 10 is provided with the feet that vertical shape is arranged, feet is that screw rod is formed, the shaft of screw rod is arranged with Compress Spring, and sand hopper 11 is fixedly mounted on feet by pilot hole that it is offered and nut, and the aperture of pilot hole is greater than the diameter of screw rod.Certainly other similar elastomeric elements as Compress Spring also can be adopted to substitute.Like this sand hopper 11 to penetrate sand device add sand time, vibrating mechanism 111 orders about sand hopper 11 and occurs to float, shake in the horizontal direction along vertical, prevents sand from sticking to the inwall of sand hopper 11, simultaneously also can prevent sand from being blocked by the discharging opening of sand hopper 11.
Further scheme is, the bottom discharge mouth place of sand hopper 11 is provided with flashboard, flashboard is connected with governor motion 112, and governor motion 112 regulates flashboard to carry out closing or opening to the discharging opening of sand hopper 11, and governor motion 112 specifically can be a horizontally disposed cylinder formation.Add after sand terminates like this, first start governor motion 112 and regulate flashboard to close discharging opening, then by sand hopper 11 with penetrate sand device and be separated, thus avoid sand to leak.
In addition, the bottom penetrating sand device is arranged penetrates Sha Zui, and penetrating sand mouth is an intubate formation extended downwards, penetrate sand device like this when noting sand in mould, intubate inserts mould inside, and what so just the entrance opening dimension of mould can be arranged is less, and the air-tightness of guarantee mould simplifies the operation operation simultaneously.Note sand terminates rear blowning installation 15 and is blown into ammonia for solidifying sand facing in cavity body of mould, allows the sand of loose shape form an entirety.The bottom penetrating sand device is also provided with the lifting mechanism of plunger tip plate in lifting, lifting mechanism comprises two vertical shapes jig arm 16 positioned opposite and cylinder 17, the L shape of arranging in opposite directions is arranged in the lower end of two jig arm 16, the middle part of two jig arm 16 with penetrate sand device and be articulated and connected by the first jointed shaft, the upper end of two jig arm 16 forms respectively by the piston rod of the second jointed shaft and cylinder 17 and cylinder body and is articulated and connected, and first and second jointed shaft is parallel to each other and arranges all in the horizontal direction.Realize clamping to upper plunger tip plate and unloading by the action of cylinder 17, thus easily lifting is carried out to upper plunger tip plate.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; to know in the utility model after contents; under the prerequisite not departing from the utility model principle; can also make some equal conversion to it and substitute, these convert on an equal basis and substitute and also should be considered as belonging to protection domain of the present utility model.
