The invention discloses a loose-joint copper piece clamping and fixing mechanism for a plastic mould. The loose-joint copper piece clamping and fixing mechanism comprises a mould cavity body, and is characterized in that the cavity body is internally provided with left and right halves of clamping blocks, the outer sides of the left and right halves of clamping blocks are internally and respectively provided with compression springs, and the compression springs contact the cavity body; the upper parts of the inner sides of the left and right halves of clamping blocks are respectively provided with half of clamping positions which are matched with copper pieces, and the lower parts of the inner sides of the left and right halves of clamping blocks are respectively provided with slide wedge surfaces; and a top block is arranged on an ejector plate of the mould, the top of the top block is triangular, and the top of the triangular top block is matched with the slide wedge surfaces. By adopting the scheme, the cavity body is internally provided with the clamping blocks, clamping and withdrawing are achieved by virtue of a spring and push-out power, the structure is simple, the motion is stable and reliable, the copper pieces do not fall off, the scrap rate is low, and the production efficiency is improved.
Description
technical field [0001] The invention relates to a clamping and fixing mechanism for loosely connected copper parts of a plastic mold, which belongs to the field of plastic molds. Background technique [0002] At present, when using plastic molds to produce plastic pipe fittings, such as when inserting copper joints, the copper parts are placed in the mold as inserts first, and then injected. In the existing technology, the parting inserts are directly taken in the mold cavity to clamp the copper parts. Therefore, during the operation of the cavity, the copper parts will be loosened or shifted and fall off, resulting in many waste products and high cost. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and provide a plastic mold with a clamping block set in the cavity, using springs and ejection power to realize clamping and ejection, simple structure, stable and reliable plastic mold joint copper part...
