The goal of the invention of the utility model is：It " rotates tangential force for of the prior art and causes mold internal model and mould
Tool external mold has relative rotation trend so that mold internal model is fixed loosely.And opposite rotation occurs for mold internal model and mold external mold
Turn, after long-time use, the friction for a long time of mold internal model outer surface and mold external mold inner surface reduces the assembling of mold internal model
The problem of precision ", provides a kind of reduced pipe extrusion molding dies.
In order to solve the above technical problems, the technical scheme adopted by the utility model is that, a kind of reduced pipe extrusion molding dies,
Including external mold, internal model and straight section portion, external mold, internal model, the combination stationary fit of straight section portion, mold external mold is in hollow cylinder with straight section portion
Structure offers reducing cavity in mold internal model and is nested in mold external mold and in straight section portion, mold external mold lower end is provided with circle
Card slot is fixedly connected with workbench, and straight section offers threaded hole and hole for hoist in portion；It is provided on the mold external mold several outer
Through-hole is provided with several interior mounting holes in mold internal model, and interior mounting hole is equipped with accessibke porosity；The accessibke porosity internal thread connects
Stop pin is connected to, the front end of stop pin is plugged in interior mounting hole.
Optimization, above-mentioned reduced pipe extrusion molding dies, the accessibke porosity is arranged in a ring along the outer surface of mold external mold.
Optimization, above-mentioned reduced pipe extrusion molding dies, the outer surface of the mold internal model is four prism type, mold internal model
Arc angling, inner surface configuration and the mold internal model outer surface shape of mold external mold are provided at the seamed edge of the four prism type of outer surface
Shape is equipped with.
Optimization, above-mentioned reduced pipe extrusion molding dies, straight section portion outer diameter is consistent with external mold outer diameter, straight section portion internal diameter
It is consistent with reducing cavity upper end bore.
Optimize, above-mentioned reduced pipe extrusion molding dies, 3-5 threaded hole is offered in the straight section portion.
Optimize, above-mentioned reduced pipe extrusion molding dies, 2-4 hole for hoist is offered in the straight section portion.
Optimization, above-mentioned reduced pipe extrusion molding dies, the internal model material is 42CrMo.
Optimization, above-mentioned reduced pipe extrusion molding dies, the straight section portion is fixedly connected with external mold by threaded hole.
The drawbacks of overcoming the prior art the utility model has the advantage of it, novelty reasonable in design.The application's
In technical solution, by the way that stop pin is plugged in accessibke porosity and interior mounting hole, fixing mould internal model is opposite with mold external mold
Position is prevented during extrusion forming, and with mold external mold relative rotation occurs for mold internal model.And the technical solution of the application
In, it is four prism type type by the outer surface of mold internal model, further improves the degree of fixation of mold internal model, prevents mold internal model from occurring
Rotation.And the outer surface of mold internal model is set as four prism type type can share the pressure of stop pin, prevent stop pin because
Stress is excessive and is broken.
