Abstract

The invention is applicable to the foundry industry and relates to a method and a mounting frame for changing vertically split molds on a core and mask firing machine consisting of a machine base and a tool roll rotatable about the horizontal axis to the core tray. Verfahrengemaesz the carriage is used with table for storing the pressed-out from the folded tool carrier cores and for receiving the mold to be changed. The mounting frame carried by the Kernablagetisch has a Auszenkontur of the mold corresponding frame with a plurality of mutually alternating positioning elements. The advantages are that it can be carried out without changing the space requirements and machine-based means changing the mold and the mounting frame allows a safe and easy positioning of the mold. {Core and mask shooting machine; vertically split mold; Core support table; Mounting frame; positioning}

Description

can be put on. The mounting frame ensures an exact positioning of the mold on the core storage table and thus for the further assembly process. Now the carriage drives mechanized into the machine under the folded tool carrier and a hydraulic cylinder presses with the attached mold to this tool carrier. The mold is coupled, the Kernablagetisch lowered and moved out of the carriage. The production readiness of the machine is established when the mold is swiveled 90 degrees into the machine, the second mold half is coupled to the andonn tool carrier and the connection between the two mold halves is released. When disassembling the mold, the procedure is to be carried out in reverse order. The advantages of the invention are that a change vertically divided molds on core and mask shooting machines with a rotatable about the horizontal axis to the core tray tool half without additional space and machine-based means is feasible and the mounting frame allows a secure positioning of the mold.

exemplary

The invention will be explained in more detail using the example of mounting a mold on a core shooting machine. The accompanying drawings show this

Fig. 1: core shooter with shuttle carriage Fig. 2: core shooting machine with shooting head

In Figure 1, the moved out carriage 1 with Kernablagetisch 2, the frame 6 with the both sides alternately arranged positioning 7; 8, for example dowels, and an attached mold 4; 5 carries shown. Accordingly, the carriage 1 with the table 2 for storing the pushed out of the folded tool ^r 3 rests cores and for receiving the mold to be changed 4; 5 are used. Figure 2 shows the core shooting machine with the shooting head 11 after a completed mold assembly. The mold half 5 is coupled in this position on the tool carrier 10 and the detachable connection 12 is between the mold halves 4; 5 canceled. To Montago a mold 4; 5, the mounting frame 6 is to be placed on the core support table 2 of the Verfahrwagens 1. Thereafter, the mold 4; 5, which is held together by a detachable connection to put with a hoist in a horizontal position on the mounting frame 6zu. The Verfahrwagen 1 moves into the machine under the folded tool carrier 3, the hydraulic cylinder 9 presses the Kernablagetisch 2 with the mold 4; 5 to the tool carrier 3 and the setter, the mold half 4 is coupled to the tool carrier 3. Now the Kernablagetisch 2 is lowered, the Verfahrwagen 1 moved out and the tool carrier 3 with the mold 4; 5 pivoted by 90 degrees to the tool holder 10 moved up automatically. Finally, the mold half 10 is coupled and the connection 12 is released.

Claims (2)

A method of changing vertically split molds on a core and mask shooting machine consisting of a machine stand and a tool tray rotatable about the horizontal tray for depositing the core, in which the complete outwardly pivoted mold is changed with a machine-centered or auxiliary machine-mounted means in that the carriage is used with table for storing the pressed out of the folded tool carrier cores and for receiving the mold to be changed. 2. Mounting frame for changing vertically divided molds, characterized in that the table (2) one of the outer contour of the molding tool (4; 5) corresponding frame (6) with a plurality of mutually alternating positioning elements (7, 8) carries. For this 2 pages drawings Field of application of the invention The invention is applicable to the foundry industry and relates to a method and a mounting frame for changing vertically split molds on a core and mask shooting machine comprised of a machine stand and a tool half rotatable about the horizontal axis to the core tray. Characteristic of the known state of the art It is known that for changing the molds for core and mask shooting machines different technical solutions are used, however, by design and technological criteria, such as type of mold guide means, division of the mold and storage of the cores are fixed. Thus, the possibilities for rationalization of the change of vertically divided molds and rotatable about the horizontal axis to the core tray Werkzeugzeälfto a core and mask shooting machine are determined. Thus, for example, in DD-PS 135698 a forming machine, in particular a grain forming machine, for the creation of forms in vertically divided core boxes shown on four square, horizontal Füiirungssäulen that are vertically displaceable, has two transversely movable frame, each of which another frame for receiving a core box half, which are pivotable relative to the transversely movable frame about a horizontal or vertical axis. To change a mold, the previously screwed in the machine mold swings around a vertical axis to the outside and after loosening the clamping devices this can be completely removed by means of a plant-based hoist and a new mold can be mounted. The disadvantages of the mold change consist in a difficult to perform assembly, in particular manipulation jnd positioning of the mold. Furthermore, DE-HS 3444343 a combined Werkzeugmontage- and inspection device for core and mask shooting machines is known which consists of a equipped with a mobile carriage base frame, a folding table with cylinder and gripping device and arm grippers for holding the fixed and the movable mold half. The device is intended to perform the complicated positioning of the heavy forming tools for attachment to the tool carrier of the receiving device. For this purpose, the complete mold must be placed with a hoist on a folding table surface and moved up by the mobile carriage to the tool holder of the recording. Disadvantages are the high plant-related, machine-related costs for the tool changing device and their additional space requirements. Object of the invention The aim of the invention is to reduce the effort to change the molds on core and mask shooting machines. Explanation of the essence of the invention The object of the invention is to develop a method and a mounting frame for changing vertically divided molds on a tool holder and a rotatable about the horizontal axis for core tray tool half existing core and mask shooting machine, the simple manipulation and positioning of the forming train without additional space to guarantee. For this purpose, according to the method of the carriage with a table for storing the pressed-out from the folded tool carrier cores and for receiving the mold to be changed. A mounting frame, supported by Kernäblagslijch, has one of the outer contour of the mold corresponding frame with a plurality of mutually alternating positioning elements. To carry out the assembly of a vertically divided molding tool on a core and mask shooting machine with a rotatable about the horizontal axis to Kernablage tool half the mounting frame is placed on the K> rnablagetisch the Verfahrwagens so that after establishing a releasable connection between the two mold halves this in a horizontal position outside the core and mask shooting machine on the core supporting the mounting frame core
