Abstract

The invention relates to devices for the processing of polymeric materials into articles and is intended for the manufacture of products such as tees with intersecting channels. The purpose of the invention is to reduce the size of the form and reduce the unproductive consumption of materials by driving the characters. In the sliders of axial marks, samples were made in which the sliders of side marks mounted under the sliders of axial marks are located, with a roller on each slide of the side mark on the axis, which has the ability to interact with a copy groove made in the slide of the axial mark. The presence of a groove in the slider prevents the axial sign from being able to transfer the slider from an asymmetrical load. 1 hp ff, 5 ill.

Description

The invention relates to devices for processing polymeric materials into articles, in particular, can be used in the manufacture of polymeric products having intersecting channels, as well as external projections of multi-channel distributors.

The purpose of the invention is to reduce the size of the form and reduce the unproductive consumption of polymeric materials by driving the characters located in one plane, with sliders placed in different planes, and expanding the technological capabilities of the form and preventing the axial sign from being skewed from an asymmetrical load.

Figure 1 is given a form with a notch along the plane of the connector; figure 2 - section aa in figure 1; on fig.Z - movable form package in the allocated position of the sliders; figure 4 - section bb-on figure 1; figure 5 - section bb In figure 4.

The mold for the manufacture of polymer products with intersecting channels contains a gating plate 1, on which a fixed holder of the matrix 2 is installed (FIG. 2) with semi-matrix 3 fixed in it; movable plate 4, on which the movable holder of the matrix 5 is fixed with semi-matrices 6 installed in it. Axial signs 7 are provided for the design of the axial channels, and side signs 8 are provided for the side channels (FIG. 1). Axial signs 7 are installed in sliders 9,

which are mounted in the guides 10. The movement of the sliders 9 axial signs 7 are inclined columns 11 (fmg.2), for fixing - locking wedges 12. Lateral signs. 8 are mounted in the holders 13 of the olzuns 14 mounted in the guides 15 and 16 (FIG. 3), which are fastened to the moving holder of the dies 5. The holders 13 of the sliders 14 side signs 8 are located in the samples 17 (FIG. 1.5), made in sliders 9 axial marks 7. Sliders 14 side marks 8 mounted under the sliders

9 axis signs 7, for which the guides

The 10 axis marks 7 are mounted on the guide 15 side signs 8. In this case, the signs 7 and 8 are located in the plane of the mold-shaped connector. To fix the sliders 14 side signs 8 in the working position in the stationary holder of the dies 2, locking wedges 18 are installed (Fig. 2). On each slide 14 of the lateral mark 8, an axis 20 is mounted on the roller 20. On the slide 9 of the axial mark 7, a copy groove 21 is made. A guide key 22 is fixed on the movable holder of the matrices 5 (Fig. 4). and in the slider 9 of the axial mark 7, a corresponding groove 23 is made. In the closed state of the form, the locking wedges 12 and 18 join with the corresponding inclined surfaces 24 and 25 of the sliders 9 and 14 of the axial 7 and lateral 8-digits.

Casting form works as follows.

After injection of the melt and technological exposure, the form is opened, while the inclined columns 11, fixed in the fixed holder of the matrices 2, move the sliders 9 axial signs 7. The copy grooves 21 of the sliders 9 act on the 20 located in them, which through the axes 19 transmit the movement to the sliders 14 side marks 8. In this way, marks are output from the shaping nests 26 (FIG. 3), after which the parts and the sprue system 27 are ejected.

When the form is closed, its elements return to their original position. Then the cycle is repeated.

The stitching forces of removing parts from axial 7 and 8 side signs are perceived by the guide key 22 interacting with the groove 23 of the slide 14

axial sign 7 in the process of its movement.

The invention makes it possible to reduce the distance between the shaping nests and, consequently, the overall dimensions.

form, while reducing the length of the gating system, which reduces unproductive consumption of polymeric materials. .

The proposed construction further extends the technological capabilities of the injection mold by reducing the distance between the inclined shaping marks, which allows to obtain parts with smaller distances between the inclined undercuts than in the forms of the known construction.
