Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: finish turning wheel hub local electric heating mould, lower mould 6 of seting up including

last mould

1 and 1 bottom of last mould, round platform face 12 has been seted up between last mould 1 and the lower mould 6, still include the lasso 3 that sets up in the 1 outside of last mould, rand 5 has been seted up to 3 bottoms of lasso, oblique guide slot 10 has been seted up to the junction inner chamber between rand 5 and the lasso 3, oblique guide slot 10 inner chamber and the laminating of

round platform face

12, 3 outside covers of lasso are equipped with

electrical heating ring

7, 3 outsides of lasso are equipped with thermocouple 2, make 7 circular telegram during operation of electrical heating ring heat ring 3, thereby reduce the shrinkage cavity defect that round platform face 12 inner chamber produced.

Specifically, as shown in fig. 3, a bayonet 11 is formed at the outer side of the connection portion between the ferrule 3 and the collar 5, and the bayonet 11 is clamped with the electric heating ring 7, so that the electric heating ring 7 and the collar 5 are mutually fixed, attached and heated.

Specifically, as shown in fig. 2, a pipeline 9 is formed on one side of the thermocouple 2, a horizontally arranged through hole 8 is formed in the top of the ferrule 3, and the through hole 8 is in clearance fit with the pipeline 9, so that the thermocouple 2 can conveniently detect the temperature of the inner cavity of the upper die 1.

Specifically, as shown in fig. 3, the ferrule 3 is in clearance fit with the upper die 1, and the inner cavity of the collar 5 is in clearance fit with the lower die 6, so that the electrical heating ring 7 heats the inclined guide groove 10 and the circular table top 12.
