Problems solved by technology

A fundamental obstacle to adoption, for example, in twin-strut die-casting machines may be the user's fear of separation of the mold halves near the mold fastening base plate in the corner areas not crossed by the struts

Embodiment Construction

[0011] exist figure 1 and 2 The closed side of the die-casting device shown in has a fixed mold fastening base 1 and a movable mold fastening base 2 to which the mold halves 3 and 4 are fastened. Single-acting cylinders 5 and 6 are used for moving the movable mold fastening shoe 2 between the closed position and the open position. A special feature of the device shown is that it has only two struts 7 and 8 . After the mold has been closed by means of single-acting cylinders 5 and 6 and the nuts 11 and 12 locked on the struts 7 and 8, pressure is applied via these struts by building up in the hydraulic units 9 and 10 for making the mold halves Closing force for 3 and 4 fit types.

[0012] Since only two of the four corners of the mold fastening bases 1 and 2 are acted upon with the closing force via the struts 7 and 8, provision is made in the embodiment shown to direct the closing force from the struts to the mold fastening base middle area of ​​. For this purpose, on the...

Abstract

Die-casting device having mold halves fastened to two mold fastening plates, wherein only two or three corners of the rectangular mold fastening plates are assigned closures for applying the mold-fitting Force strut, wherein at least one mold fastening base (1, 2) is provided with a pressure plate (13, 14) or a pressure frame (17) on the side facing away from the associated mold half (3, 4) , the struts (7, 8) act on the pressing plate or pressing frame, and the pressing plate or pressing frame transmits at least part of the closing force to a far away part of the mold fastening bottom plate (1, 2). In the area of ​​the struts (7, 8).

Description

technical field [0001] The invention relates to a die-casting device with mold halves fastened to two mold fastening bases, wherein only two or three corners of the rectangular mold fastening bases are provided with means for applying force to clamp the mold together. Type of closing force strut. Background technique [0002] Instead of the customary four struts, an injection-cast arrangement with only two, possibly three struts, would have considerable advantages. Removal of the molded part or placement on the side onto the core pack of the adjoining mold etc. can be almost as simple as with an injection molding machine without struts. It will also save the cost of the C-frame necessary for the strutless die-casting machine. [0003] Although there are theoretical considerations for a strutless die casting machine, there are no such products on the market. One reason for this is that it is economical to distribute a given closing force over many struts. A fundamental ob...
