Abstract
The invention discloses an injection mold straight ejection swing upending core-pulling demolding device, which comprises a swing rod (1), a guide block (2) and a straight ejection rod (3). The invention adopts the device composed of the swing rod, the guide block, and the straight ejection rod. The swing rod is provided with a guide groove, the guide block is provided with a guide pin, and straight ejection rod is provided with a rotating shaft. The upending core block is fixed at the upper end of the swing rod, and the lower end of the swinging rod is rotatably connected to the upper end of the straight ejection rod. The guide groove and the guide pin are in sliding cooperation connection. During work, the guide pin guides the swing rod to do straight line and swing motion under straight ejection of the straight ejection rod, thus driving the core pulling of the upending core block from the upending structure of a product. The technical scheme provided by the invention overcomes the problems of large mold and high cost in the prior art. Straight ejection swing is employed to replace inclined ejection and inclined movement, so that the purposes of reducing the injection mold body and lower the cost can be reached.
