The production process of syringe mould


    What are the parts of a syringe mould, and what are their functions?

    (1) Forming part. That is, after the mold is assembled and closed, the cavity part of the plastic product is directly formed as a component of the plastic product, such as a convex mold, a concave mold, a core, a rod, or an insert.

    (2) The mold clamping guide part. It is a component set for correct alignment of the central axis when the moving and fixed molds are closed, such as guide posts, guide hole sleeves or inclined taper parts.

    (3) The product launch part. It is the parts used to push the molded injection product out of the molding mold cavity, including ejector rods, fixed plates, push plates, and cushion blocks.

    (4) The core extraction part. When demolding plastic products with pits or side holes in injection molding, first pull out the core mechanism parts for pits and side holes, such as the frequently used inclined guide posts, inclined sliders, and bent pins and other core-pulling mechanisms.

    (5) The heating and cooling part of the mold body. It refers to a control system that adapts to the temperature of the injection molding process of plastic products, such as resistance heating plates, rods and their electronic control components; the cooling part uses circulating cooling water pipes, etc.

    (6) The supporting part of the mold body. It refers to the auxiliary parts to ensure the correct operation of the mold body, such as movable and fixed mold pads, positioning rings, lifting rings and various fastening screws.

    (7) Pouring melt channel. It refers to the runner that can lead the molten material injected through the nozzle to the cavity of the forming mold. It can usually be divided into main runner, runner, bushing mouth (gate) and cold chute.

    (8) Vent holes. It refers to the part that can discharge the air in the mold cavity. Generally, small products do not need to have special vent holes, and the air in the cavity can be exhausted from the gap between the matching parts; for large injection products molds, vent holes must be provided.
