Abstract

The invention relates to the manufacture of rubber technical products and is intended for recharging molds for vulcanization presses. The purpose of the invention is to reduce the material consumption of the device while increasing the stroke of the slide. For this, the pivot-lever scissors are installed in a plane transverse to the direction of movement of the slide 6. The scissors hinges are connected to the slide 6, the stem and the base 13 through intermediate hinges 7, 11, 18. The scissors have the ability to rotate in the plane of movement of the slide 6. The latter is from the power cylinder through scissors moves to extreme positions. This moves the mold. 2 Il.

Description

The invention relates to the field of manufacture of rubber technical products, is intended for recharging molds of vulcanizing presses and is an improvement of the well-known 5 device by auth. No. 1523367.

The purpose of the invention is to reduce the material consumption of the device while increasing the stroke of the slider.

Figure 1 shows the proposed us-10 three hundred; on fig? same side view.

The device for reloading molds contains a frame 1, on the upper plate 2 of which floor-mounted guides for the press are installed | γ ·· ι lower 3, middle 4 15 and upper 5 for three-plate molds.

In the grooves of the lower guides 3, a slider 6 is installed with grippers for interacting with the mold. Slider 6 is connected to the lower part via an intermediate hinge 7 ”and an axis 8 ka.” A wearable element is installed in the axial direction to the transverse direction of movement of the slider 6. The second end of the swinging lever, by axis 10, is connected to the gay bracket through an intermediate hinge 11 (-5 nom. 12. fortified on the basis of 13 frames 1.

The swinging growl 9 is made in the form of articulated lever scissors, which include two-arm levers 14, single-arm levers 15, central 16 and peripheral 30 17 hinges.

The swing arm 9 is connected to the central hinge 16 through an intermediate hinge crosspiece 18 with the rod of the actuator cylinder 19 of the swing arm 35 mounted on the support 20.

Guides 3 5 molds are mounted on vertical columns 21 and are moved up to open them; the upper guides with the power cylinders are 40 frames 22, the middle guides with the power cylinders 23. while the lower guides remain stationary and are attached to the plate 2 of the shaft I.

The device operates as follows - »1 volume.

11 slider 6 with its grips from the far right pusher moves from the power cylinder 19 by lever 9 and moves the mold with the blanks laid in it to the extreme left position, where it comes off the rails 3-5 and enters the vulcanizing press. When moving the slider from one extreme position to another, the hinge-lever system of the lever 9 from the beginning to the middle of the stroke of the slider, folding, shortens, and from the middle to the end of the stroke of the slider 6 lengthens again, while the axis 8 of the connection of the slider 6 with the intermediate hinge 7 moves horizontally in a straight line. After vulcanization of the products, the slider 6, with its grips, moves the mold along the guides 3 until it growls to its rightmost position. Then, the upper front plate of the mold moves vertically upward by the power cylinders 22 and 23 and is torn off from the lower plate of the mold and from each other. The PressForm is freed from the vulcanized products, it is cleaned and the blanks from the rubber compound are laid in it. The guides 5 and 4 with the plates of the mold are lowered down until the plate of the mold is closed Then the cycle of the device is repeated.

The device allows to reduce the dimensions of the swinging lever in extreme positions due to the fact that it is perpendicular to the plane of movement of the slider, as a result of which the material consumption of the device decreases and the stroke of the slider increases.

Claims (1)

Claim Device for reloading molds on autosw. No. 1523367, characterized in that, in order to reduce the material consumption of the device while increasing the stroke of the slide, the articulated lever scissors are installed in a plane transverse to the direction of movement of the slide, and their hinges are connected to the slide, rod and base through intermediate hinges with the possibility of rotation.
