It is distributed in the border of die cavity more effectively shaped article to be cooled down, is more beneficial for the follow-up demoulding.Owing to this practicality is new
During type molding, temperature is higher, and in order to preferably ensure service life, the bottom of described mould is provided with rear mold thermal insulation board 5, described
Rear mold thermal insulation board 5 is placed in below bottom plate.
Processing molding method of the present utility model under described briefly below:
A kind of belt pulley is held concurrently the processing method of helical gear product mould, comprises the steps:
S1, cast, mould forward and backward template matched moulds is to pouring the original state of beginning, and castable enters from note cast gate, passes through
Runner enters into die cavity；
S2, molding, castable is pressurize molding in die cavity；
S3, cooling, carry out the cooling in mould by the cooling system in mould, and combine temperature sensor and carry out temperature
Monitoring；
S4, die sinking, forward and backward template carries out die sinking after the cooling period, and front mould mold insert departs from the belt pulley upper end of product, owing to producing
The helical teeth lower end of product is placed in rear mold mold insert, waits the demoulding.The cast of product, molding, all with existing die casting molding side
Method is similar to, due to the particularity of this product, so need to carry out the improvement of technology when the demoulding.
S5, the demoulding, ejector retainner plate 6 promotes thimble to exert a force shaped article, and part power is put on ring gear mold insert 10 by product,
During thimble pushes away, ring gear mold insert 10 is driven to rotate, due in the mold insert briquetting of setting on described ring gear mold insert
Being provided with graphite 14 and ripple Lunella coronata silk 15, graphite 14 plays the lubrication between ring gear mold insert 10 and mold insert briquetting 11, and ripple
Lunella coronata silk 15 makes ring gear mold insert 10 when rotating, it is possible to reduce the rotational resistance of ring gear mold insert 10, thus be well on de-
Mould.
The mode that employing mold insert briquetting in this utility model is combined with ring gear mold insert, can avoid using bearing, thus
Avoid strengthening ranking, greatly reduce cost.Meanwhile, cooling system will not be impacted so that cool down more abundant.Meanwhile, by
Less relative to bearing depanning mode in die space area occupied of the present utility model so that the most plastic four products of mould
Product, described die cavity is arranged on and pours around mouth, is greatly improved working (machining) efficiency.
This utility model still has multiple specific embodiment, all employing equivalents or equivalent transformation and the institute that formed
Have technical scheme, all fall within this utility model claimed within the scope of.
