Eight Categories Of Injection Molds

Eight categories of injection molds

(1) Single parting surface injection mold

When the mold is opened, the movable mold and the fixed mold are separated to take out the plastic part, which is called a single parting surface mold, also called a double-plate mold. It is the simplest and most basic form of injection mold. It can be designed as a single-cavity injection mold or a multi-cavity injection mold according to the needs. It is the most widely used injection mold. mold.

(2) Double parting surface injection mold

The double parting surface injection mold has two parting surfaces. Compared with the single parting surface injection mold, the double parting surface injection mold adds an intermediate plate (also called movable gate plate, It is equipped with gates, runners and other parts and components required by the fixed mold), so it is also called three-plate (moving plate, intermediate plate, fixed plate) injection mold, which is often used for single-type point gate feeding For injection molds with multiple cavities or multiple cavities, when the mold is opened, the intermediate plate is separated from the fixed template at a fixed distance on the guide post of the fixed mold, so that the casting system condensate can be taken out between the two templates. The double parting surface injection mold has complex structure, high manufacturing cost, and difficult parts processing. Generally, it is not used for the molding of large or super large plastic products.

(3) Injection mold with lateral parting and core pulling mechanism

When the plastic part has side holes or undercuts, it is necessary to use a laterally movable core or slider for molding. After injection molding, the movable mold first moves down for a certain distance, and then the inclined section of the bending pin fixed on the fixed template forces the slider to move outward, and at the same time, the push rod of the demolding mechanism pushes the pusher plate to make the plastic part self-molding Take off the core.

(4) Injection mold with movable molded parts

Due to the special structure of plastic parts, the injection mold is required to be equipped with movable forming parts, such as movable punches, movable concave molds, movable inserts, movable thread cores or rings, etc., which can be combined with the plastic parts during demolding. Move out of the mold together, and then separate from the plastic part

Above content mentions 5 key concerns of the customers while working with Injection Molds manufacturers, including cost, lead time, quality, manufacturing expertise, and production capacity. These concerns have different priorities but are all closely related to the overall performance of the manufacturer. Hence, manufacturers can address customer's concerns by providing transparent information and excellent customer service to build trust and enhance customer loyalty.
