The gathering portion includes an outer shell, a hollow inner shell and a number of fans. The inner shell is received in the outer shell. The inner shell includes a number of vent. The fans are positioned between the outer shell and the inner shell for blowing ions into the inner shell through the vents. The tray is configured for containing the plastic members passing through the gathering portion.

Abstract: A detachable threaded rod is used in an injection mold, and includes an operation portion, a molding portion, and a screw. The operation portion includes a rod part, the rod part defines a mating hole and a screw hole on a bottom surface of the mating hole. The molding portion includes a front end, a rear end, and a side surface connected between the front end and the rear end. The molding portion defines a cavity on a front end. The molding portion includes a mating portion extending from the rear end and received in the mating hole. The mating portion defines a through hole communicating with the cavity. The molding portion defines external threads on the side surface. The screw penetrates the through hole and screwing in the screw hole, the operation portion is fixed with the molding portion by the screw.

Abstract: Angle pin structure for ease of male and female mold disengagements includes an angle pin member, a sliding block, and an elastic unit between the angle pin member and the sliding block. The angle pin member includes a base, and the elastic unit is received in the base. When the sliding block moves close to the angle pin member on assembly of a male and female molding device, the elastic unit is elastically compressed between the sliding block and the angle pin member. When the molding device is to be broken open and the sliding block moved away from the angle pin member, the elastic force helps to push the sliding block away.

Abstract: A device is used for separating a molding core and a block in a molding groove of the molding core. The device includes a substrate, an abutting element, and a pushing element. The substrate includes a first fixing plate and a second fixing plate opposite to the first fixing plate. The abutting element is fixed on the firs fixing plate, and extends towards the second fixing plate. The second fixing plate defines a threaded hole. The pushing element defines a screw thread coupled with the threaded hole. The pushing element has an end adjacent to the first fixing plate. The end of the pushing element defines a receiving groove. The pushing element can rotates in the threaded hole to push the molding core to move towards the first fixing plate, and thus the abutting element enters into the molding groove to push the block into the receiving groove.
