Description

fixed rotary upper forming element 11

The mechanism 5 of the rotation of the side walls 3 is made in the form of a power cylinder 12, pivotally connected at one end with the supporting frame 1, the other end with the side wall 3.

Punches 7 of the ejector mechanism 6 are installed in horizontal guides 13 and are located coaxially with the longitudinal axis of the side walls 3 when the latter are horizontal. On the outer side of each of the punches 7, a strip 14 is attached with a relief that repeats the relief of the bottom 4 of the cassette shape 2

The operation of the plant in the manufacture of, in particular, gypsum products is carried out in the following sequence.

Stage I - molding products The side walls 3 are installed in a vertical position on the bottom 4 of the mold 2 (Fig. 1) In this case, the upper forming element 11 is in the vertical position (position a), freeing the compartments of the cassette form 2 for casting. The molding plaster mix from a mixing device (not shown) is poured from above into the compartments of the cassette form 2, after which the upper forming element 11 is pivoted on the axis 10 lowered onto the side walls 3 (position b) and embedded in a freshly molded product. top of products. The excess gypsum mixture enters the gap of the mecht by the forming element 11 and the side walls 3 and is removed outside the limits of the form 2.

Stage II - dismantling products.

After the mixture has hardened to a strength of 0.1–0.2 MPa (for mixtures on a gypsum in a G-4 brand — in 4–5 min), the stem of the power cylinder V2 is extended. rotate the side walls 3 forms of

vertical position to horizontal. The upper forming element 11 is rotated on the axis 10 by 180 °, opening the end of the product (position in figure 2). To the opposite end of the pushing mechanism b, the punches 7 are brought in, which, moving further horizontally, push the molded articles to the receiving device 8.

After lubrication of the bottom 4 and the side walls 3, the latter are turned by the cylinder 12 from a horizontal position to a vertical one and the cycle of manufacturing the products is repeated.
