1、The parts that give the shape, structure and size of the molding material are generally composed of a core (punch), a concave cavity, a threaded core, and inserts.
2、Medical injection mold casting system It is a channel that leads molten plastic from the nozzle of the injection machine to the closed mold cavity. It is generally composed of a main channel, a branch channel, a gate and a cold well.
3、The guide part of the medical injection mold is a guide part set to ensure accurate alignment when the movable mold and the fixed mold are closed, and has a guiding and positioning effect. It is composed of a guide post and a guide sleeve. Some medical injection molds are still ejecting plates A guide part is set on the upper part to ensure the smooth and firm movement of the demoulding tissue. It is composed of demolding organization, core pulling organization, machine mold conditioning system, and exhaust system.
4、The demolding organization of medical injection molds is used to complete the demoulding of plastic parts and casting systems. It has many structural forms. Commonly used demolding organizations such as ejector rod, ejector tube, top plate and pneumatic ejector are generally composed of ejector rod, reset rod, and slingshot. , Mandrel fixing plate, top plate (top ring) and top plate guide column/guide sleeve and other combinations.
5、Core-pulling organization of medical injection molds For plastic parts with side holes or undercuts, before being ejected and demolded, side core-pulling or separating sliders (lateral parting) must be carried out to allow for smooth demoulding.

6、Medical injection mold mold temperature conditioning system In order to meet the injection molding process's requirements for mold temperature, a mold temperature conditioning system (such as cooling water, hot water, hot oil and electric heating system, etc.) is required to adjust the mold temperature. Equipment.
7、In order to discharge the gas in the mold cavity smoothly, the exhaust system of the medical injection mold often sets an exhaust groove at the parting surface of the mold, and the gap between the push rods or other movable parts (such as: sliders) of many molds can also be removed. to the exhaust effect.
