Abstract

The invention relates to the processing of thermoplastics in an injection molded product and can be used on injection molding machines to drop products from ejectors in injection molds. The purpose of the invention is to simplify the design. For this, the movement mechanism of the ejector device 1 is provided with a guide 5 and a slider 2. The slider 2 is connected to the fixed part of the machine by the thrust 3 through block 4. Moreover, the slider 2 is able to exit from the interaction with the pusher plate 10 at the end of travel of the movable plate 6. 1 Il.

The invention relates to the processing of thermoplastics into articles by injection molding and can be used on injection molding machines for dropping products from ejectors in injection molds.

The purpose of the invention is to simplify the design. In the drawing given the proposed device.

The device contains a tripper device 1, mounted on a slider 2, tgu 3, made in the form of a cable or chain connecting through block 4 a slider 2 with a fixed part of the injection molding machine (not indicated), a guide 5 attached to the movable plate 6, the mold half 7 mounted on the movable plate 6, the coupling half 8, mounted on a fixed plate 9, plate ejector 10,

The device works as follows.

After the required holding under pressure, the half-form 7.8 is opened. The movable plate 6 of the injection molding machine moves the mold half 7 and the moving mechanism of the ejector 1 during its operation, while the ha 3 weakens and the slider 2 is lowered onto the plate of the ejectors 10, the plate of the ejectors 10 stops, and the mobile plate 6 and part of the half-form 7 continues to move. the course

the movable plate 6 of the slider 2 is ejected from the plate of the pushers 10 and under the force of gravity falls between the plates of the half-mold 7. With the slider 2 the resetter 1 falls, removing the product from the ejectors 10 of the form of the injection molding machine. When closing the half-form 7, 8 t hectares 3 raises the slider 2 to its original position. When moving, the slider 2 is located in the guide 5, which allows the slider 2 and the dumper 1 to be guided with great precision. Molten thermoplastic material is injected into the forming cavity and then the cycle repeats.
