Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to casting technology, and more particularly to an apparatus for making cores using a heated core box.

The device of the invention can be used, for example, in mass production plants in the sanitary industry, the automotive industry, the electrical industry and the mechanical industry.

For a method and apparatus for making cores from fluidized sand in heated core boxes, German Patent No. 2,239
, No. 057 is known.

In the above method, fluidized sand is forced under pressure into a heated core box, the box is then sealed and held closed for a sufficient period of time to allow the sand to solidify, and then , the box is opened and the core is removed. This method makes it possible to create any core that solidifies to form natural channels or porous ducts that allow effective ventilation of gases.

The above equipment consists of a container and feeder for the initial sand component,
having a mixer with a gate for closing the outlet, an extrusion cylinder with a plunger, a metering chamber, a sliding dump A- with a nozzle that can be extended and a push-up table,
The device operates as follows.

The sand is first fed into a mixer, mixed therein, and then sent to an outlet where N fluidized sand is formed. Then, it flows into the measuring chamber, which is closed from the bottom side by the Danzo. Once the metering chamber is filled with sand, the gate is actuated to close the mixer outlet, the Dan, R- is moved to move the metering chamber into alignment with the nozzle, and the cable is then actuated to remove the core. The box is lifted so that the core box is pressed against the nozzle. A plunger is then actuated by the extrusion cylinder to force sand into the core box.

Once the push-down operation is complete, the core box is sealed to prevent sand from escaping from its entrance. After a time has elapsed during which the air bubbles are destroyed and the sand is immobilized, the core box is sent to the next location, the dan, e- is activated again to close the metering chamber from the bottom, and the nozzle is opened. , the residual sand is removed from the nozzle, the plunger is returned to its original position, the gate is actuated to open the mixer outlet, and the above cycle is then repeated.

However, under certain conditions, the pressure within the box can increase to a value sufficient to overwhelm the weight of the top of the core box. Therefore, if the core box is not kept closed in the stuffing area for the required time after the stuffing and sealing operations, the top of the box will be lifted and the sand will be thrown out and spread over the joint surfaces. This results in the production of defective cores. In addition, since the solidification of sand is accelerated by the evaporation of moisture, the assimilation time increases considerably compared to the conventional high-temperature phase method and low-temperature assembly method. Holding for a longer time and increasing the solidification time of the sand substantially lengthens the core production cycle. Therefore, the above-described apparatus cannot compete with apparatus for hot phase processes and low temperature assembly processes, making it unsuitable for use in mass production plants.

The above-described apparatus lacks a means for continuously connecting the upper and lower parts of the core box to each other from the time the stuffing operation begins until the time the core box is separated. If the core box is held in the open/closed position for a long time between the table and the stuffing mechanism,
If the pressure inside the box is low enough that the top of the box will not be lifted when the box is separated, the production capacity of the machine will be reduced and, ultimately, the box It is impossible to completely eliminate vertical vibrations in the upper part of the core, and such vibrations generally impede the dimensional accuracy and quality of the finished core.

U.S. Pat. No. 4,241,779 shows a core-making machine using a heated core box, which machine has a holding frame, on the upper stage of said frame, sand preparation means with a mixer, and
A mechanism for compacting fluidized sand into a core box is weighed, said mechanism having a metering chamber housing a packing actuator placed on a cloth body which can be moved by a drive means;
Further placed on the upper stage are a pusher for moving the core box through the heating chamber, a core box separation means having a part for pushing the core out of the core box, and a means for feeding the completed core; This means has a transport means having a receiving plate with parts to receive the core, and a carriage on which a holder for receiving the finished core is attached; on the lower stage of the holding frame there are a lifting table, a transfer table and a carriage. A conveying means is placed for transporting the core box in the direction of operation d. Each of the core boxes has an upper part and a lower part, both parts being connected by suitable drive means placed on the upper stage of the holding frame at the stuffing mechanism;
Separated by suitable Wl drive means placed near the core box separation means, a gate is placed on the top of the core box, this gate being placed on the upper stage of the holding frame at the stuffing mechanism. It also cooperates with drive means for closing the gate and means for opening the gate located at the core box separation means.

The above-mentioned means for connecting the upper and lower parts of the core box are made in the core box, and are located at the front and back of the heating chamber (in the direction of operation).
It is actuated by suitable means placed therein.

The means for connecting and separating the upper and lower parts of the core box has a horizontal par, and the said par has a chimney integrated at the lower part and cooperates with the connecting means and the vertical par fixed on the upper part.
A groove and a hole A are formed at one end of the vertical par to engage with the horizontal hole.

The machine described above operates as follows.

The lifting table is actuated to lift the core box and send the core box to the sand packing mechanism. The drive means is actuated to move a horizontal par located in the lower part of the core box;
The tapered body is inserted into a hole in the vertical hole of the VCR above the upper part of the core box to firmly connect the upper and lower parts of the core box. This operation makes it unnecessary to actually keep the core box in place after stuffing;
Therefore, the production cycle of the machine is shortened.

Fluidized sand is supplied from the mixer of the sand preparation means to the metering chamber of the packing mechanism, from which the sand is forced into the core box through the core box inlet. The core box is then sealed and sent to a heating chamber by a pusher. When the next core box is fed into the heating chamber, the first core box leaves the heating chamber and is fed onto the transfer table by the feeding means. At the end of this run, the horizontal par engages the core feeding means and is moved to its original position. As a result of this movement, the two parts of the core box are separated. The seal of the core box is released at the same time that the taper of the horizontal hole is taken out of the taper hole of the vertical hole. The core box is then opened by actuation of the separating means, at which time the vertical part is disengaged from the horizontal part due to the groove. After the core is removed from the core box, the core is placed on the holder of the holding frame by the core feeding mechanism, the core box is reassembled by the core box separating means, and then transferred to the transfer table. is lowered onto the transport vehicle and returned to the stowage location.

(- However, the above machine is unsuitable for producing cores with different dimensions and core prints (print holes in the core) in different locations, and the production possibilities and applicability of this machine are limited. Limited to thick.

The metering chamber of the packing mechanism, from which the fluidized sand is forced into the core box via its outlet, the axis of this chamber coincides with or follows the axis of the entrance of the core box. Since the mixer in contact with this weighing chamber (from which the fluidized sand will be sent into the weighing chamber) is fixed to the holding frame of the machine, the entrance of the core box can be moved ( -The disadvantage is that their positions cannot be changed when

To change the distance and location of the entrance of the core box, the position of the drive means connecting the upper and lower parts of the core box.

It is necessary to change the position of the actuator that closes the gate of the core box, the position of the means that separates both parts of the core box and opens the gate, and the position of the pusher that has the means for ZR punching the core. All positions must be strictly matched to the core box entrance positions.

Furthermore, a change in the dimensions of the core or the position of its print requires a corresponding change in the distance between the holding bodies of the holding frame and between the receiver in the core feeding mechanism and the gripping fork of the feeding means. do.
