The invention relates to devices for the continuous molding of predominantly concrete and reinforced concrete products using the vibropressing of the molding material.

The purpose of the invention is to improve the quality of products.

Fig. 1 schematically shows an installation for molding concrete products, a longitudinal section; in Fig.2 is the same, in the initial position of the injection punch; on fig.Z - section aa in figure 1.

The installation for molding concrete products consists of a movable frame 1 on wheels 2 moving along the guides 3 of the base 4. On the frame 1 a smoothing plate 5, a vibrating plate 6, a bunker 7 for a concrete mix are mounted.

The holders 8 with vibrators 9 are fixed on the transverse beams 10 of the frame 1. The longitudinal sliding boards 11 are fixed on the frame. The delivery punch 12 is connected to the rod of the power cylinder 13 mounted on the frame 1. Guides

longitudinal sides 11 and the base.

As the punches 12 move in the direction b, the concrete mixture is injected into the molding chamber, where the concrete mixture that has entered the chamber is pressed out. Reactive forces from the pressure of the punches on the compact Q weft concrete move the frame 1

together with the molding chamber and holders 8 in the direction a. Thus, continuous, extrusion molding of a concrete product is carried out.

Fibrova fittings are fed to the upper zone of the product as follows. At the start of the 12 punches movement

for the punches 12, hollow cores 8 and longitudinal beads 11 serve. The kneading bar 19 of the drum 18 lies on

Anson 12 is made with an L-shaped working surface 29 of compacted concrete formed by an L-shaped working surface of 14 punches 12,

whose surface 14. Between the hopper 7 for concrete and the vibrating plate 6 on the frame 1 is mounted a hopper 15 for dispersed fiber with a drive drum feeder 16 consisting of a body 17, a drum 18 with a recess 19 and a driven gear 20 mounted on the axis of the drum 18.

The drive rotation of the drum 18 consists of a camera 21, a toothed rack 22, a pinion 23 placed in the housing 24, a lever 25 mounted on the axis of the gear 23, and a fork stop 26 mounted on one of the punches 12.

The installation works as follows.

The concrete mix is loaded into the hopper 7, and the fibrov valve is loaded into the hopper 15. When you turn on the cylinder 13, the punches 12 simultaneously make a reciprocating motion. During the course of the punches 12 in the direction a, the concrete mixture from the hopper 7 enters the molding chamber formed by the smoothing plate 5, the vibrating plate 6, the bar feeder 16,

At the beginning of the movement of the punches 12 in the direction b by means of the groove 28 of the fork support 26, the drum 18 rotates in the direction d by 180 ° and blocks the outlet opening in the housing 17 of the drum feeder 16. With the further movement of the punches 12 in the direction b, the fiber portion mixes with the concrete mix, which is compacted. Thus, fiber reinforcement remains only in the upper zone of the product.
