SU1211073A1 - Universal unit for casting moulding of polymeric material articles - Google Patents

Description

2, Fencing block, 1, characterized in that, in order to enable the products to interfere with the holes, it is provided with fixed stops for interaction in the injection molding plate

The invention relates to the processing of polymeric materials into products and can be used in the preparation of the production of new plastic products in a press industry using a universal block as a re-adjustable tooling.

The purpose of the invention is to expand the range of manufactured products by providing an increase in the specific pressing pressure and ensuring the possibility of pushing the products against the holes.

Figure 1 shows the universal unit, closed position; in FIG. 2, the same open position; Figs 3-6 show various types of holes in the product.

The universal unit for injection molding of polymeric materials contains a movable part 1 with a plate 2 and a casting punch 3 fixed on it, a fixed part 4 with a plate 5 and a casting chamber 6, a plate 7 of punches 8, a plate 9 of matrix 10 with a fixed in it Basically with the casting chamber 6, a divider 11 made in the form of a rod, a plate 12 and 13 YOU are rigidly connected to the plate 5, the stops 14 installed in the plate 2, interact with the plate 7 of the punches 8, in the plate 5 there are holes 15, under the lugs 14, ti gi 16, connecting the slab of the plate 12 and 13 is pulled out nodding and plate 5 of the casting chamber 6. The spindle 17, which interacts with the lower gi and the cylinder of the press, is fixed to the ejection plates 12 and 13 of the ejection. The stops 14 interact with the plate 18 discharge products,

A universal block for injection molding of polymer products from a punch plate, in the plate of the casting chamber there are holes for the stops, and the braces connecting the ejection plates and the plate of the casting chamber are filled with steps.

ny materials works as follows.

The injection chamber 6 is loaded with a press material, the injection punch 1 is lowered and the forming cavity of the matrix 10 is filled. After holding the pressure, the movable part 1 of the universal unit rises, and the injection punch 3

is separated from the casting chamber 6 and the splitter 11, after the final opening of the universal block, the spindle 17 is actuated from the lower press hydraulic cylinder and the ejection plates 12 and 13 are moved upwards. The gigs 16 push the plates 5 and 7, and as these plates move upward, the parts are separated from the dies, and the product discharge plate 18 meets with the stops 14, the Casting punch 1 enters the loading chamber 6 and pushes the press residue out of it, and the stops 14 stumble upon a plate 18 for the discharge of products and, moving it, remove the obtained parts from the punches 8. Next, the manufactured parts are removed from the pressing zone, the movable part 1 with the plate 2. the plates 12 and 13 are ejected

0 PIA under the action of the lower hydro

The lindra presses are also moved down, freeing the casting chamber 6 to set the next portion of the press material.

- The universal unit is ready for pressing in the next batch of products. The implementation of the universal unit, the hell of the injection molding of products from polymeric materials according to

 The invention will allow the range of manufactured products to be expanded by providing an increase in the specific pressing pressure.
