Guide rail type arc swinging core-pulling mechanism

Abstract

The invention relates to a guide rail type arc swinging core-pulling mechanism. The guide rail type arc swinging core-pulling mechanism is arranged on an injection molding machine, and a mold provided with a core-pulling part is arranged at a fixed mold part of the injection molding machine. The guide rail type arc swinging core-pulling mechanism comprises a guide plate, a guide groove, a guide pin, an L-shaped swing rod, a locking mechanism, an arc-shaped guiding block and a sliding block, wherein the L-shaped swing rod comprises a first rod and a second rod; the joint of the first rod and the second rod is rotatably fixed on a movable mold part of the injection molding machine; the guide plate is fixed on the fixed mold part of the injection molding machine, the guide groove is formed in the guide plate, a certain included angle is formed between the guide groove and the vertical direction, the guide pin can move along the axial direction of the guide groove, the guide pin is rotatably connected with the other end of the first rod; the other end of the second rod is fixedly connected with the sliding block, the sliding block is fixedly connected with the core-pulling part in the mold, and the movable mold part is provided with the locking mechanism, so that the sliding block is locked by the locking mechanism when the guide pin rises to the top end of the guide groove. The mechanism can realize the mechanism movement by utilizing mold opening force of the mold injection machine, so that the cost is reduced, and an energy source is saved.

Description

technical field [0001] The invention relates to an arc core-pulling mechanism, in particular to a guide-rail type arc swing core-pulling mechanism. Background technique [0002] The arc core pulling mechanism and the injection molding machine are widely used in the production of plastic products that require arc core pulling. It is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. The structure design of the current arc core-pulling mechanism is too complex, such as rack and pinion plus slider linkage mechanism, inclined guide column arc core-pulling mechanism, etc., often require additional power outside the injection molding machine to complete the core-pulling action , the energy consumption is relatively large, therefore, it is necessary to develop an arc core-pulling mechanism that does not require external power, has a simple structure, and is easy to use.
