Embodiment Construction

[0025] exist figure 1 In the process, under the control of the lock, the mold is opened by the injection molding machine. Under the control of the lock 14, the lower fixed template 3, the lower movable template 4, the upper fixed template 7, and the upper movable template 8 are opened to drive the upper push plate 12. The upper push rod fixing plate 13, the lower push rod fixing plate 15, and the lower pushing rod fixing plate 16 push out the product and the flow channel at the product; then push out the plate 5 from the flow channel, open the flow channel plate 6, and pull out the main flow channel; finally Push out the flow channel push-out plate 5, release the main flow channel, the base plate 1, the lower support block 2, the upper support block 9, the panel 10, and the positioning ring 11 are motionless. The injection molding machine closes the mold, the push rod is reset first, and the above process is repeated.

Abstract

The invention relates to a pipe fitting stack mold, which is mainly used for mass and efficient production of small plastics products. The actual injection quantity of the conventional single layer cavity mold is only 20 to 40 percent of the maximum injection quantity of an injection molding machine because of mold capacity limitation of the injection molding machine, so the conventional single layer cavity mold cannot make full use of the injection characteristics thereof and cannot improve production efficiency. The pipe fitting stack mold adopts a multi-layer cavity, does not need to improve any equipment, and only most effectively uses an axial space of the injection molding machine. The technical key comprises the qualifying of products, the design of a flow channel, sequence controlof separating and opening the mold and the design of a resetting mechanism. The pipe fitting stack mold adopts a prolonged nozzle to reduce the length of the main flow channel; the pipe fitting stackmold has grouped qualifying with consistent type of the end faces of the products and a pre-reset structure; and the aggregation and ejection of the products and the flow channel are completed by moldopening linkage of injection molding machine. The pipe fitting stack mold is novel in structure, makes full use of the mold capacity space of the injection molding machine, improves capacity efficiency and doubles production efficiency.

Description

technical field [0001] The pipe fitting lamination mold of the invention relates to the plastic pipe fitting injection mold for building water supply and drainage. Background technique [0002] Plastic product manufacturers have higher and higher requirements for production efficiency and quality. However, when small plastic products need to be produced in large quantities and efficiently, the traditional single-layer cavity mold is limited by the capacity modulus of the injection molding machine. Often the actual injection volume is only 20-40% of the maximum injection volume of the injection molding machine. Its injection characteristics cannot be fully utilized, and production efficiency cannot be improved. Contents of the invention [0003] The multi-layer mold for pipe fittings does not need to improve any equipment, but the most effective use of the axial space of the injection molding machine, the running speed is only a few percent slower than the single-layer mol...
