Description

Sand shake-out device using vibration

Technical field

The present invention relates on auto parts etc., mo(u)lding (workpiece) by casting, by vibration, make sand shake-out device using vibration attached to the sand on the workpiece, the workpiece that particularly falls attached to the core sand of the hollow bulb of workpiece, in detail, the workpiece that relates to desire knockout remains on the vibration platen, by a vibrating motor, makes this shake table panel vibration, in view of the above, make the sand shake-out device using vibration of the workpiece that falls attached to the sand on the workpiece.

Background technology

The great majority of various machine components such as auto parts are to pass through casting.On the mo(u)lding that is cast (workpiece), adhere to a large amount of sand, the operation that this sand that adheres to is fallen.

As fettler's method of workpiece, hit the workpiece be attached with sand by hammer in the past, workpiece is applied vibration, make technology that sand falls by known.For example, workpiece is remained in the case of sealing, the sand shake-out device using (No. the 3077681st, utility model registration) of the workpiece that hits with hammer, make the work support counter-rotating, make and emit oral area towards the below, hit the workpiece reversible type sand shake-out device using (spy opens 2003-305559 number) of workpiece and have the anti-audio amplifier of workpiece side and the anti-audio amplifier of hammer side with hammer, become closed chamber by two box-shapeds, the hammering device (No. the 3205897th, patent) etc. that hits workpiece with hammer is by known.

But these devices all are by hitting workpiece with hammer, make the form that falls attached to the sand on the workpiece, and not only device maximizes, and, also produce because of strike causes noise, cause the problem of environmental pollution etc. because of dispersing of sand.

Have again, workpiece is applied vibration,, especially make the device of the core sand whereabouts of hollow bulb also apply for (the special 2004-243118 of hope) by the applicant by this vibration force by a pair of vibrating motor.

This installs because use two vibrating motors, so the vibration of sand falls the effect excellence, still, because be two vibrating motors, so have maximization, uneconomic shortcoming.Have again, under the situation of using two motors,, need carry out the distribution of weight of two motors, the configuration of elastic support member rightly for two motor run-in synchronisms.

The problem that the present invention will solve provides a kind of sand shake-out device using vibration, and this sand shake-out device using vibration replacement to the knockout technology in the past that workpiece hits, applies vibration to workpiece with hammer, in view of the above, especially use a vibrating motor, realize the knockout of workpiece, so, the inevitable miniaturization of device, do not had to hit the noise that causes, and prevented the environmental pollution that dispersing of sand caused yet, had again, overcome the problem when using two motors, improved the shortcoming that exists in the conventional art.

Summary of the invention

In order to solve above-mentioned problem, according to the present invention is a kind of sand shake-out device using vibration, be by vibration, make the sand shake-out device using vibration of the mo(u)lding that falls attached to the sand on the mo(u)lding, it is characterized in that, have by elastic support member, be positioned in the vibration platen on the base station, be arranged on the keeper of the mo(u)lding on this vibration platen, and motor that links with this vibration platen, after the mo(u)lding that will desire knockout remains to above-mentioned keeper, make above-mentioned vibrating motor running, make the shake table panel vibration, in view of the above, the mo(u)lding that keeps on keeper is applied vibration, the sand of mo(u)lding is fallen.

The invention effect

The formation of the invention described above is that the workpiece that will desire knockout remains on the vibration platen, by a vibrating motor, make this shake table panel vibration, in view of the above, make workpiece, particularly the core sand of hollow bulb falls, and therefore, does not need the such big device in hammering device chamber in the past, be miniaturized, and, do not had to hit the noise that causes, and can not produce the environmental pollution problems that dispersing of sand caused yet.

Have again, because device of the present invention only has a vibrating motor, so, be miniaturized, and economical.Under the situation of using two motors, in order to make two motor run-in synchronisms, must carry out the distribution of weight of two motors, the configuration of elastic support member rightly, still, and under one situation, restriction that need not be such.

The specific embodiment

Below, use accompanying drawing, describe the present invention in detail.Fig. 1 is the vertical view of a concrete example of relevant sand shake-out device using vibration of the present invention, and Fig. 2 is its side view, and Fig. 3 is its stereogram.

As Fig. 1, Fig. 2 and shown in Figure 3, the present invention is by vibration, makes the sand shake-out device using vibration A of the mo(u)lding that the core sand of the hollow bulb 2 of mo(u)lding (workpiece) 1 falls, and vibration platen 5 is positioned on the base station 3 by elastic support member 4.On this vibration platen 5, the workpiece keeper 6 that clips mo(u)lding 1 and keep is being set, have again, this vibration platen 5 and a vibrating motor 7 link.As elastic support member 4, be rubber, metal spring, air pressing spring etc., insulation prevents to vibrate the obstruction to the vibration platen to the vibration of base plate face.

The relevant sand shake-out device using vibration A of the present invention that constitutes of resembling in this wise when knockout, at first, as shown in Figure 4, deflate from the workpiece keeper 6 that shrinks that expands by air, shrink, by work piece holder guide 8, draw in clamp rod 9, make the space of inserting workpiece 1.

Then, as shown in Figure 5, after workpiece 1 being configured to the space of making that deflates, air being put into workpiece keeper 6 make it to expand, the pressing piece 10 of the front end by clamp rod 9 is pushed workpiece 1, and workpiece 1 is remained on workpiece keeper 6.

Like this, after workpiece 1 is remained on workpiece keeper 6, then, a vibrating motor 7 runnings that make and vibrate platen 5 bindings make 5 vibrations of vibration platen, in view of the above, the workpiece 1 that is held part 6 maintenances is applied vibration, make attached to the sand on the workpiece 1, particularly the core sand of hollow bulb 2 falls.In addition, under the situation that the core sand that makes hollow bulb 2 falls and removes, the hollow bulb 2 as if granular solid content being dropped into workpiece 1 then can fall effectively and remove.

The possibility of utilizing on the industry

The formation of the invention described above is that the workpiece that will want knockout remains on the vibration platen, by vibration Motor makes this shake table panel vibration, accordingly, makes the sand that adheres to, particularly hollow bulb of workpiece Core sand falls, and therefore, does not need the such big device in hammering device chamber in the past, by small-sized Change, and, do not had to hit the noise that causes, and can not produce that dispersing of sand cause yet The problem of environmental pollution.

Have again, because the present invention when making the shake table panel vibration, only has a vibrating motor, So, not only economical, and also simplification of structure, and be miniaturized. That is, because this Bright only have a motor, so, although in the situation of two motors, owing to need two The motor synchronous running, thus need to carry out rightly the configuration of distribution of weight, elastic support member, But, in one situation, be not subjected to such restriction. Therefore, vibrating shakeout of the present invention Device is very high in the possibility that casting technology field is widely used.
