Abstract

The invention relates to a mold for the production of angular, provided with breakthrough moldings. It is an object of the invention to provide a mold, can be made efficiently with the form body with little effort for the molds. This object is achieved according to the invention in that the mold is designed as a multiple mold with an upwardly open molding box (1) and in the molding box (1), angled Zwischenwaenden (2), wherein the Zwischenwaende (2) of Distanzkoerpern (3; 4) and the spacer bodies (3) of a limb of each intermediate wall (2) are arranged on the inside of the angle and the spacer bodies (4) of the other limb are arranged on the outside of the angle.

Mold for cast resin body

•

The invention relates to a casting mold for the production of angular perforated moldings.

Characteristic of the known technical solutions Transformers with a large stray field, z «B« welding trench furlers, require the core pressed parts to be made of insulating material. · To give the core pressings the required bending stiffness, one often uses angle profiles made of hard paper or hard textile the processing very expensive «In the production of Kernpreßteile made of molded material, this disadvantage is indeed avoided, but the cost of the dies is for relatively small quantities or · small series too high« Furthermore, it is well known. Producing moldings from Gießharzroassen «The CH-PS 490 948 introduces a device for the serial production of moldings from cast resin, in which a large number of individual forms of a transport device through a heating zone and a pouring device are moved" small series but this system is underutilized so that the production "is unprofitable because of the high technical effort DE-aS 1,180,926 shows in Figure 3. in order to cast several small parts in \ a capsule a capsule form ·, the Allowance must be cavities in several floors and possibly the star arranged around a sprue «

In addition, foundry technology is generally known as so-called stacking forms «

In these forms is disadvantageous «that they are relatively complex in construction and can be poured with them only uncomplicated moldings ·

Object of the invention

The invention aims to avoid the stated disadvantages.

Explanation of the essence of the invention

The invention has for its object to provide a mold for the production of angled, provided with apertures moldings «with which these parts can be produced efficiently with little effort for the forms.« This object is achieved by the features specified in the characterizing part of the main claim «two advantageous developments are the subject of points 2 and 3 «

Ausführungebeispiel

Below solid invention will be explained in more detail with reference to a drawing

In an upwardly open molding box 1 angular profile-like partitions 2 are used «These partitions 2 are distanced from conical spacers 3; 4, so that they are held in position« The spacers 3; 4 «which are attached to the partitions 2 form apertures for subsequent screwing elements "in order to mold the moldings ent, the spacers 3, 4 are arranged on each intermediate wall 2 such that on one leg the spacers 3 on the inside of the angle and on the other leg the spacers 4 on the outside of the angle «The molding box is moved with a stacking direction of the intermediate walls 2.

Baren side wall 6 executed. The movement of the side wall 6 is carried out by means of a press screw 7 are. Are all the intermediate walls 2 inserted into the mold box 1, the intermediate walls 2 are clamped by the movable side wall 6 before the Gießharzeinguß · After filling the casting resin in the interstices and after a certain residence time Curing of the casting resin is released for removal from the press screw 7 · The mold box 1 is overturned and removed «Now alternately an intermediate wall 2 and a molded body 5 are removed« The arrows 8 shown in the drawing indicate the removal direction of the intermediate walls 2 and Arrows 9, the decrease direction of the molded body 5 at.

With this mold, larger numbers of angle profile moldings can be produced in a rational manner · Taking into account that for a small series production otherwise a larger number of individual forms would be required »which are then also individually, for example, to move the heating zone, pouring device and curing zone, is for this Inventive Vielfachgießform the technical complexity relatively low and a rational production technology for angle profile molding possible ·
