Abstract
The utility model discloses a mold core of an injection molding machine. The mold core comprises a columnar mold core body, wherein the two ends of the columnar mold core body are respectively provided with external threads and respectively screwed with front and rear top heads; a helix body is sleeved outside the columnar mold core body and between the front and rear top heads; the two ends of the helix body respectively lean against the inner sides of the front and rear top heads; and a clearance inside the helix body forms an injection molding material filling chamber outside the columnar mold core body. The mold core disclosed by the utility model is simple in structure; a petroleum pipeline protector processed through the mold core and the external threads of the mold core are molded by one step, particles are also uniform, the work efficiency and precision are both high, and the defects of low work efficiency and poor precision caused by repeated processing are avoided.
Description
Technical field
The utility model relates to injection machine field of components, specifically a kind of injection machine die.
Background technology
Injection machine is equipment conventional in the process of manufacture of petroleum pipeline protector, and the die of injection machine claims again die cavity, embeds the formation die core in mold base template.In prior art; the die of injection machine be shaped as the shape that is equal to petroleum pipeline protector; be column construction; and the outside of petroleum pipeline protector is mostly with external screw thread; when the petroleum pipeline protector of tubular construction is on injection machine after injection mo(u)lding; need to be placed on lathe and do screw thread processing, not only inefficiency, and batch processing also can cause low precision.
Utility model content
The purpose of this utility model is to provide a kind of injection machine die, and the petroleum pipeline protector processing by it and external screw-thread one-shot forming thereof, to avoid repeatedly processing the defect of the low and low precision of the operating efficiency that causes.
The technical solution of the utility model is as follows:
A kind of injection machine die, include cylindricality die body, it is characterized in that: the two ends of described cylindricality die body are respectively equipped with external screw thread and are screwed with respectively forward and backward top, the outside of cylindricality die body is set with conveyor screw between described forward and backward top, described spirochetal two ends lean respectively the inner side in forward and backward top, and the gap of conveyor screw inside forms injection molding material in the outside of cylindricality die body and fills chamber.
Described injection machine die, is characterized in that: described spirochetal external diameter is slightly less than the external diameter of forward and backward top, and spirochetal internal diameter is slightly larger than the external diameter of cylindricality die body.
The beneficial effects of the utility model:
The utility model is simple in structure, the petroleum pipeline protector processing by it and external screw-thread one-shot forming thereof, and uniform particles, and operating efficiency and precision are all higher, have avoided the operating efficiency that repeatedly processing causes lowly and the defect of low precision.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to Fig. 1, a kind of injection machine die, include cylindricality die body 1, the two ends of cylindricality die body 1 are respectively equipped with external screw thread and are screwed with respectively forward and backward top 2,3, the outside of cylindricality die body 1 is set with conveyor screw 4 between forward and backward top 2,3, the two ends of conveyor screw 4 lean respectively in the inner side of forward and backward top 2,3, and the gap of conveyor screw 4 inside forms injection molding material in the outside of cylindricality die body 1 and fills chamber 5.
In the utility model, the external diameter of conveyor screw 4 is slightly less than the external diameter of forward and backward top 2,3, and the internal diameter of conveyor screw 4 is slightly larger than the external diameter of cylindricality die body 1.
Claims (2)
