Plastic pipe die product outward ejection mechanism

Abstract

Provided is a plastic pipe die product outward ejection mechanism. The mechanism comprises a die upper compound plate and a lower compound plate. A fixed die plate is arranged under the upper compound plate. A fixed die insert is arranged in the fixed die plate. Two support blocks are arranged on the lower compound plate. A movable die bottom plate is arranged on the two support blocks. A movable die plate is arranged on the movable die bottom plate. A movable die insert is arranged in the movable die plate. A die cavity is arranged between the movable die insert and the fixed die insert. Pipe fitting inner wall cores are arranged in the die cavity. An upper ejection plate and a lower ejection plate are arranged between the two support blocks. Ejection pins are connected with the upper ejection plate. The plastic pipe fitting die product outward ejection mechanism is characterized in that, the die cavity comprises a pipe fitting body die cavity and a pipe fitting flaring die cavity, an ejection cavity is arranged on the movable die insert at one side of the pipe fitting flaring die cavity, the ejection cavity is communicated with the flaring die cavity through a connection channel, the ejection pins go through the movable die bottom plate, the movable die plate and the movable die insert, and matches with the ejection cavity. An upper surface and a lower surface of a plastic pipe processed and shaped through the mechanism have no ejection marks, and products are smooth and beautiful, and have good quality and high level.

Description

technical field [0001] The invention relates to an ejection mechanism for plastic pipe fitting mold products, which belongs to the field of plastic molds and is mainly used for processing plastic pipe fittings and the like. Background technique [0002] Plastic molds are used to produce plastic products, such as plastic pipe fittings (elbows). After injection molding, the inner wall of the pipe fitting needs to be core-pulled. After the inner wall core of the pipe fitting is pulled out, the power of the injection molding machine is used to push the mold. The ejector mechanism drives the thimble to eject the product out of the mold. However, in the prior art, when the product is ejected out of the mold, the thimble is generally pushed against the outer wall of the product body. After the product is completely cooled, there will be a top mark on the outer wall of the product body, which will affect the appearance and reduce the product grade.
