Mold for injection molding machining of notebook computer shell and rapid demolding method of mold

Abstract

The invention discloses a mold for injection molding machining of a notebook computer shell and a rapid demolding method of the mold. The mold comprises an upper mold, a lower mold, a supporting rod, a first fixing block, a second fixing block, a T-shaped rod, a first spring, a T-shaped block, an inclined block, a second spring, a square block, a square groove, a reset spring, a magnetic ring, a supporting plate, a lead screw, a first inclined rod, a second inclined rod, a movable plate, a third spring, a micro motor, a screw rod, a nut, a rotating rod, a rotating pin, a reset coil spring and a micro bearing. A T-shaped rod moves to enter the second fixing block, the T-shaped rod moves to extrude an inclined block, the inclined block moves to drive the T-shaped block to move and extrude a second spring. When the inclined block is aligned to a limiting groove in an annular side face of the T-shaped rod, under the action of an elastic force of the second spring, the T-shaped block moves to drive the inclined block to move to enter the limiting groove, and then the position of the T-shaped rod is fixed; the elasticity of the first spring facilitates attachment of the first fixing block and the second fixing block.

Description

technical field [0001] The invention relates to a mold for injection molding, in particular to a mold for injection molding of a notebook casing and a quick demoulding method thereof. Background technique [0002] Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine, and after cooling and solidifying, a molded product is obtained. [0003] There are certain defects in the mold county of traditional injection molding processing. The lack of convenient installation mechanism for the upper mold and the lower mold makes it inconvenient to install the upper mold on the lower mold. From the beginning, the lack of disengagement mechanism makes it i...

Problems solved by technology

[0003] There are certain defects in the mold county of traditional injection molding processing. The lack of convenient installation mechanism for the upper mold and the lower mold makes it inconvenient to install the upper mold on the lower mold. Since the lack of a disengagement mechanism, it is inconvenient to separate the injection molded part from the moving plate
