Description
Technical Field
The utility model relates to a thick wall return bend injection mold terminal surface advances to water structure belongs to the injection mold field.
Background
The injection mold is adopted to produce a plastic pipe fitting, such as a thick-wall bent pipe, the traditional technology adopts middle pouring or side pouring when pouring, but in the production process, due to the wall thickness of the pipe fitting, the required pouring injection pressure is large, the impact force generated by the pouring injection pressure impacts a core, the core is easy to be eccentric, the product is eccentric and scrapped, and the waste is large.
Disclosure of Invention
The utility model aims at overcoming prior art's shortcoming, provide one kind and adopt to advance gluey along the core terminal surface, effectively slow down to advance to water the injection impact force, avoid the eccentric thick wall return bend injection mold terminal surface of core to advance to water the structure.
The utility model discloses thick wall return bend injection mold terminal surface advances to water technical scheme of structure is: the injection molding device is characterized by comprising a fixed template and a movable template, wherein a fixed die insert is arranged below the fixed template, a movable die insert is arranged on the movable template, a bent pipe die cavity is arranged between the movable die insert and the fixed die insert, bent pipe opening core blocks are respectively arranged at two ends of the bent pipe die cavity, pipe wall cores are respectively inserted into the two bent pipe opening core blocks, the two pipe wall cores extend into the bent pipe die cavity to be spliced in an opposite insertion manner, a sprue is arranged in the fixed template, a transverse runner is arranged on the movable die insert and is communicated with the sprue through the fixed die insert, one end or two ends of the transverse runner extend to the bent pipe opening core blocks, a sprue inlet is arranged at the sprue inlet, the sprue inlet is communicated with the bent pipe die cavity, and during injection molding, plastic raw materials are injected from the sprue, flow into.
the utility model discloses a thick wall return bend injection mold terminal surface advances to water the structure, during moulding plastics, the plastics raw materials pours into from the runner, flow into the return bend die cavity through horizontal runner from advancing the runner, with thick wall return bend injection moulding, owing to advance the runner setting in return bend oral area pellet department, also be exactly the oral area inflow of plastics raw materials from the return bend, the terminal surface advances to water promptly, after the plastics raw materials flow into the return bend die cavity, flow along the pipe wall core, it is full of to fill the return bend die cavity, make thick wall return bend injection moulding, because the plastics raw materials flows along the pipe wall core, the impact force that the production of flowing (injecting) has effectively been slowed down, avoid the.
