Clamping member core resetting mechanism for tee plastic covered iron pipe fitting mould

Abstract

The invention discloses a clamping member core resetting mechanism for a tee plastic covered iron pipe fitting mould. The mechanism comprises an upper compound plate and a lower compound plate, wherein the upper compound plate is connected with a cavity frame and a cavity; a mould leg and a top plate are arranged on the lower compound plate; the top plate is provided with an ejector rod; the mould leg is provided with a core frame and a core; an outer slide block is arranged on one side of the core frame and is connected with a tee core; a tee clamping member is sleeved outside the tee core and is matched with a tee joint of an iron stand; the outer wall of the core frame is provided with an oil cylinder; a piston rod of the oil cylinder drives the outer slide block to slide outwards; an upper clamping tongue and a lower clamping tongue are arranged in the outer slide block and are provided with an upper compression spring and a lower compression spring respectively; a clamping port is formed between the upper clamping tongue and the lower clamping tongue; heads of the upper clamping tongue and the lower clamping tongue are provided with an upper clamping tongue oblique plane and a lower clamping tongue oblique plane respectively; a head of the piston rod is provided with a clamping groove and a trapezoidal plane; the clamping port is matched with the clamping groove of the piston rod; the trapezoidal plane is tangential to the upper clamping tongue oblique plane and the lower clamping tongue oblique plane; the oil cylinder body is provided with an upper plug rod and a lower plug rod; heads of the upper plug rod and the lower plug rod are provided with an upper plug rod oblique plane and a lower plug rod oblique plane respectively; and the upper plug rod oblique plane and the lower plug rod oblique plane are tangential to the upper clamping tongue oblique plane and the lower clamping tongue oblique plane.

Description

technical field [0001] The invention relates to a three-way plastic-clad iron pipe fitting die clip core reset mechanism, which belongs to the field of plastic moulds. Background technique [0002] Injection molds are used to produce plastic products, such as plastic pipe fittings, especially tee pipe fittings that are injection molded with PE raw materials. In order to save raw material costs, increase the compressive strength of pipe fittings, and effectively control the deformation of pipe fittings, additional installation is made in tee pipe fittings. Iron frame (piece), that is, three-way plastic-coated iron pipe fittings. In the existing three-way plastic-clad iron pipe fittings, when injection molding, a straight-through clip is first inserted into one end of the straight-through core, and then the iron frame is inserted into the outside of the clip, and then another straight-through clip is inserted into the other side of the straight-through core. Fix the iron fram...

Problems solved by technology

Its disadvantages are: since the tee core is driven by the oil cylinder, when the tee clamp is inserted into the tee of the iron frame, the iron frame is easily displaced and deformed by collision, resulting in poor quality of the pipe fittings, or even scrapped
