Molding box, preferably made of metal, for producing standards from concrete and the like.

The invention relates to a molding box consisting of movable Side parts and mold bottom, preferably made of metal, for producing moldings from concrete and the like * with high accuracy and of different dimensions

Metal molds are known which, prior to the production of the moldings from concrete and the like, each with the required accuracy adjusted, fixed or locked.

These metal molds have the defect that they require a lot of work for the respective new setup and these manual operations cause disruptions in mechanized manufacturing processes for molded articles made of concrete and the like.

Furthermore, metal molds of high accuracy are known which, in addition to the accuracy of the molded parts, also have complicated connecting means, such as, for example, hydraulics, electromagnetism and the like for these Require molded parts.

These metal molds have the deficiency that they require a high manufacturing cost due to these connecting means and only found predominantly for large-scale production.

Likewise, metal molds are known in which less expensive Connecting means are used for the molded parts, such as screws, eccentrics, wedges, levers, hinges and others.

These connecting means have the defect that the concreting process and forces generated by the compaction of the concrete and the like are transmitted directly into the connecting means genes and thus inaccuracies after repeated use develop.

The purpose of the invention consists in the exterior of a molding box, with which, with a minimum of manual effort, moldings of high accuracy can be produced economically, even in small numbers can be and the required iiohe accuracy in the manufacture of the molded parts oiine over a long period of time ■ Adjustment unu. dgj .. guaranteed and the versatile Possible application requires low manufacturing costs

The explanation is based on the task of Connection 'of the side parts of the mold with the base of a molding box to cut eggs in the production of moldings mxt same Dimensions adjusted, fixed or locked only once, slightly readjusted, fixed in the case of shapes with changed dimensions or can be locked, immovability of the molded parts guaranteed against each other and with mechanical manufacturing processes uhiie difficulties applied; can be·

According to the invention, this problem is solved in that the Mold side parts with the mold bottom by in principle known two-axis Forcibly, they are fixed to one another.

There are 2 variants for each version of the biaxial forced guidance intended.

According to the invention, the first variant of the forced guidance consists of U-Profixen with an elongated hole, which is attached to the bottom of the mold by bolts · The position of the bolt is determined by means of clasps according to the well-known fit principle "while - bore" set. According to the invention, there is the second variant of Forced guidance from ü-Profxlen with hole that goes through to the bottom of the mold attached taper bolts are guided. The position of the taper bolt is determined by means of a conical sleeve according to the known "Cone - conical sleeve" fit principle specified.

The invention is to be explained in more detail below using exemplary embodiments will. In the accompanying drawings show:

The mold bottom 1 has recesses 2, which in the extreme case Extend in a grid over the entire mold base 1, for the inclusion of the forced guidance and pressing means. The location of these recesses 2 is not critical, so that they only need to be produced with normal accuracy. The mold side parts 3 are manufactured in the accuracy required for the sides of the briquettes, whereby because of the correspondingly arranged forced guidance and pressing means, a lightweight construction, such as stiffened folding profiles, meets high accuracy requirements. she receive on the side facing the mold bottom 1, the corresponding recesses 4 for the forced guidance and pressing means. the Forced guidance means consisting of the bolt 5 and the clasp or tapered bolt 7 and cone 8 are separated with a high degree of accuracy manufactured. Their attachment in the recesses 2 on the mold bottom 1 can be done with a thread oäsr the like. The mold side part 3 can with a nut 9 over the clasp and a U-profile 10 or

be pressed over the cone 8 and a U-profile 10 on the bottom of the mold. Be on the temporarily assembled metal mold the mold side parts 3 with high accuracy, according to the Requirements, e.g. B. with inside micrometer, with gauge extensions, calibrated uiid by screwing the nuts 9 on the Mold bottom 1 pressed. In this state, the U-profiles 10 the forced guides on the mold side parts 3 by welds 11 for larger series or screws 12 for smaller series fixed immovably by formations. When assembling the molding box take the mold side parts 3 by the positive guidance in each case the position achieved during the measurement to each other and to the bottom of the mold 1, according to the accuracy of the priority control, on again. With a correspondingly precise training of the forced guidance can can achieve an accuracy of + 1 im, even with repeated Assembly does not deteriorate, since the stresses on the mold side parts 3 during the production of the moldings on the

Friction of the mold side parts 3 on the Jform base 1, generated by the Contact pressure of the forced guidance or simple contact pressure is provided by means of Transfer bolts 13 and nuts 14 or the like to the mold base 1 and thus do not place additional demands on the forced guidance As long as a certain type of molding is being manufactured, the bolts 5 or taper bolts 7 remain for the positive guides and the screws 13 of the Anpi'eßstellen on the mold, while the Furmseitenteile 3 for cleaning purposes or ugi · can be removed can · For the production of shaped pieces of other dimensions The same positive guide means can be used again on a mold base 1; weruen. An identification of the compulsory notice; tex and the La ^ e of the associated recesses 2 in the mold base 1 allows a .remen aer bolts 5 or üegelboizen 7 after a Production period or the re-auctioning of the auction as this Molding type after a period of time by according to the Identification of the original position of the Jj'ormseitenteile 3 wiedex ' heart will exit, so that 3 on one and the same mold base 1 in the Change several types of moldings with high accuracy can be.
