Description

A kind of small-sized sand casting shakeout

Technical field

The present invention relates to sand casting apparatus field, more particularly to a kind of small-sized sand casting shakeout.

Background technology

The knockout of casting is one of the important procedure in sand casting production process.Knockout is exactly in casting-up and cooling To after certain temperature, casting mold is crushed, casting mold is made to be detached with sandbox, casting is detached with molding sand.At present in sand-cast production In the process, the development of moulding mechanization is still lagged behind in this process procedure of casting falling sand, or even uses artificial carry out type Sand separation greatly limits the efficiency of castings production processing, currently, sand removing method commonly used in Foundry Production is vibration Method (impingement method) realizes that knockout, shakeout are divided into machine by the method for generating vibration using the collision between casting mold and shakeout Tool oscillatory type and Electromagnetically vibrating, wherein mechanical-vibration type shakeout is divided into eccentric vibration-type and inertial vibrative, the latter's application It is more universal, a kind of shakeout for sand casting of inertial vibrative is just devised in the present invention.

Invention content

The present invention provides a kind of small-sized sand casting shakeout, and the structure of the shakeout is simple, can effectively realize The knockout of molding sand detaches, and can substitute manual operation during mass production, can greatly improve the efficiency of production.

To achieve the above object, the present invention provides technical solution below：A kind of small-sized sand casting shakeout, including Pedestal, rack, vibration generating mechanism, active elastic component, driven elastic parts and casting placing box, the rack are equipped with two A, two racks are fixedly mounted on pedestal, and two racks are distributed with respect to base center axis line mirror image, the vibration generation machine Structure is made of motor, drive crank, connecting rod and driven rocking bar, and the motor is fixedly mounted on pedestal, the drive crank with The output shaft of motor is fixedly connected, and described connecting rod one end is hinged with drive crank, and the other end is hinged with driven rocking bar, the active In an elastic parts rack installed therein, the active elastic component includes that No.1 hinged seat, No.1 spring and No.1 connect The side of bar, driven rocking bar and No.1 hinged seat is hinged, there are two the No.1 spring is set, and is distributed in the two of No.1 hinged seat Side, two equal one end of No.1 spring are fixedly connected with No.1 hinged seat, and the other end is fixedly connected in rack, the No.1 connecting rod It is fixedly connected with No.1 hinged seat, and is fixedly connected with the bottom of casting placing box, the driven elastic parts is mounted on another In a rack, and it is hinged with the bottom of casting placing box.

Preferably, it is fixed with motor fixing plate on the pedestal, motor is fixedly mounted on motor fixing plate.

Preferably, the rack is equipped with bit-avoiding slot.

Preferably, the driven elastic parts includes No. two hinged seats, No. two springs and No. two connecting rods, No. two springs If there are two, two No. two springs are located at the both sides of No. two hinged seats, and one end of two No. two springs with No. two hinged seats Side be fixedly connected, the other end is fixedly connected in rack, and described No. two connecting rod one end are fixedly connected with No. two hinged seats, The other end is fixedly connected with the bottom of casting placing box.

Preferably, it slips through the net equipped with two blocks of knockouts in the casting placing box.

It is using the advantageous effect of above technical scheme：Structure of the invention is a kind of small-sized sand casting shakeout, type Sand casting to be separated will be placed in casting placing box, and the course of work of the shakeout specifically, starts motor, motor Drive crank rotation is driven, drive crank drives driven rocking bar to rotate by connecting rod, when drive crank is clockwise to three (needle To the direction of Fig. 1) during the rotation of position, driven rocking bar will rotate counterclockwise, and while the rotation of driven rocking bar, connecting rod can will Driven rocking bar pulls to the right, i.e., No.1 hinged seat can move right, and the No.1 spring for being located at the No.1 hinged seat left side in this way can quilt It tenses, and the No.1 spring on the right of the No.1 hinged seat will be compressed, when drive crank has moved to three position, No.1 Hinged seat just moves to right end, as drive crank is rotated further, during being rotated from three to six-o ' clock position, No.1 hinged seat is the process replied from right end to center equilbrium position, the mistake rotated from six-o ' clock position to nine o'clock position Cheng Zhong, No.1 hinged seat move downward, and the No.1 spring positioned at the left side is compressed beginning, and will positioned at the No.1 spring on the right It is tightened up, from nine o'clock during position is rotated to ten two positions, No.1 hinged seat is since left to center equilbrium position Movement, driven elastic parts is consistent with the motion conditions of active elastic component, is located at equidirectional No.1 spring and No. two springs Stressing conditions it is consistent, motor rotation, will all repeat the above process weekly, No.1 spring and No. two springs are tightened up or press repeatedly Contracting, since the presence of elastic force will produce side-to-side vibrations, is located in casting placing box while casting placing box double swerve The molding sand attached on casting will will produce separation, in conclusion the structure of the shakeout is simple, can effectively realize molding sand Knockout detaches, and can substitute manual operation during mass production, can greatly improve the efficiency of production.
