Description

Discharge end piece support mechanism

The invention relates to polymer molding processing technology, in particular to a support mechanism for a discharge end piece.

In order to solve the conventional polymer raw material supply technology such as extrusion or injection, the discharge end piece is moved downward from the upper side of the vertical mold station, and when the mold in the mold station is abutted for feeding, the discharge end is required. The piece moves through the top plate above the mold station. "There is a lack of long displacement stroke, resulting in waste of derivative energy and reduced manufacturing efficiency. In the new patent case of No. M256813 in China, it is in the vertical mode. An open sliding space for the discharge end piece to be slid therein is arranged in the top plate of the station, so that the discharge end piece can be moved between different mold stations without removing the top plate, so as to shorten the displacement stroke of the discharge end piece during feeding. .

Since the discharge end piece abuts against the mold to form a polymer material flow passage, the abutment between them needs to be tight to avoid the seepage of the polymer raw material, but the patent case is sufficient for the discharge end piece. In the feeding stroke, the effect of shortening is obtained, but in the state in which the discharge end piece is in contact with the mold after the movement of the injection stroke, the reaction force abutting on the mold is transmitted to the conventional polymer raw material supply device. In particular, it is not an ideal technique for a columnar heating extruder for directly melting the polymer raw material and directly contacting the discharge end member.

Therefore, the main object of the present invention is to provide a support mechanism for a discharge end piece, which can support the reaction force when the discharge end piece abuts between the molds, and avoid affecting other components of the polymer raw material supply device. The effect of protection.
