SU1423262A1 - Installation for making moulds and cores - Google Patents

Abstract

The invention relates to installations for the manufacture of molds and cores from a liquid-fluid mixture in a heated snap-in. The purpose of the invention is to expand the technological capabilities and improve the quality of the forms and cores. The installation for making molds and cores consists of a bed 1, a hydraulic cylinder 2, a press cup 6. The press cup 6 is made in the form of a vertically standing sleeve with a movable bottom plunger 5. The upper part of the sleeve faces the tooling, is open and can be installed on it interchangeable nozzle 14 with a hole of one configuration or another. I il.

; The invention relates to a foundry industry and can be used to make complex shapes and cores from a fluid-wetting mixture that is curable in a snap.

The purpose of the invention is the expansion of technological capabilities and the improvement of the quality of forms and cores.

The drawing shows the proposed installation (v.riant), a general view. I B. Frame 1 is fitted with a hydraulic cylinder 2, the rod 3 of which is also hydrodilINDrom; on the top end14

The center of the movable rod 4 of the hydraulic cylinder 3 is equipped with a replaceable plunger 5,. which is the bottom of the press cup 6. On the press glass 6, the equipment 7 is installed with the shape of the skin element 8 and the hole 9. The area of the inlet 9 is always at least 1.5-2 times the area of the resulting form 10 (in the light). The sleeve 6 is fixed on the cover 11 of the rod 3. A mixture 12 is poured into the sleeve 6. A support plate 13 is placed on top of the bed 1. A replaceable nozzle 14 is placed on the sleeve on top of the sleeve.

The installation works as follows.

The tool 7 is installed above the press cup 6, the rod 3 is turned on to lift, which raises the sleeve with the mixture to the tooling, the tool is pressed by the sleeve 6SK to the base plate 13. Then the lifting of the plunger 5 is turned on, which squeezes the mixture 12 into the cavity of the mold 10, where the mixture is cured under the action of heat heated equipment 7.

After a certain holding time, the rod 3 is lowered, the snap-in is transferred to the position of the connector, and the pressure rod

the mixture by the stroke of the plunger 5 is squeezed out of the press cup and collected. Sew into a waste collection tank or into a mixer tank for reuse (not shown).

The implementation of the invention allows to reduce the cost of machinery and equipment Q by eliminating the slide device, reduce the consumption of the mixture, improve the quality of the molds and strayness and reduce the number of scrap. In addition, the removal of the remainder of the mixture from the press cup is extremely simple: with the plunger of the hydraulic cylinder of the press-pressing mechanism, the mixture is squeezed out of the cup and removed to the waste container. The proposed installation can be used to make rods and shapes of different types by configuration and weight.
