Detailed description of the invention
This utility model discloses a kind of belt pulley and holds concurrently helical gear product mould, as shown in figs 2-4, wraps successively Upper mounted plate, front template 1, rear pattern plate 2, backing plate 3, ejector retainner plate 4 and bottom plate are included.Thimble 6 it is provided with below described die cavity, The bottom of described thimble 6 is connected with ejector retainner plate 4, is additionally provided with mould foot between described backing plate 3 and ejector retainner plate 4.During the demoulding, described top Needle plate 4 drives thimble to promote product motion.This ingredient is consistent with prior art, therefore is not described in detail in this.
Be respectively arranged with the front mould mold insert 8 and rear mold mold insert cooperated in described front template 1 and rear pattern plate 2, described before It is provided with die cavity between mould mold insert and described rear mold mold insert.Described die cavity includes under a belt pulley upper end with straight-tooth and helical teeth End, described belt pulley upper end is placed in the top of helical teeth lower end by connecting shaft, and described belt pulley upper end and described helical teeth lower end Coaxial, the belt pulley upper end of die cavity is arranged in front mould mold insert 8, and the helical teeth lower end of die cavity is placed in rear mold mold insert.
In order to when the demoulding, can preferably make helical teeth lower end carry out the demoulding, in described rear mold mold insert, it is provided with ring gear edge Part 10 and mold insert briquetting 11, described ring gear mold insert 10 engages with the helical teeth lower end of described die cavity.Described mold insert briquetting 11 is placed in tooth Transmission lubrication assembly, described tooth it is provided with between the top of ring mold insert 10, and described mold insert briquetting 11 and described ring gear mold insert 10 Ring mold insert 10 rotational band moves product stripping.
Specifically, the inner ring of described ring gear mold insert 10 is provided with helical teeth, and described helical teeth engages with the helical teeth lower end of die cavity. Described ring gear mold insert 10 upper surface offers an annular groove 15, is provided with ripple Lunella coronata silk in the bottom of described mold insert briquetting 11 12, described ripple Lunella coronata silk 12 slides in groove 15, and is evenly equipped with graphite block 14 between adjacent described ripple Lunella coronata silk 12.Described Ripple Lunella coronata silk can also adopt in other ways, such as collision bead screw or the form of other tightening steel balls.Described graphite block is permissible Other cup greases etc. are used to replace.
In principle, described groove can also be arranged on bottom mold insert briquetting, carries out still through ripple Lunella coronata silk and graphite Lubrication rotates.
Owing to product is when pressurize molding, in mould, temperature is higher, in order to enable the most moulding and keep the temperature in mould Degree controls, and is provided with cooling system and temperature sensor 16 in described mould.During due to molding, forward and backward mould all can produce heat, In order to preferably monitor temperature, being typically respectively arranged with one group of temperature sensor 16 in forward and backward mould, each group is provided with two Individual, and often group temperature sensor between be oppositely arranged.
Described cooling system is to be placed in the interior annular water channel 9 formed of forward and backward mould mold insert.The arrangement in described water route 9 can be entered Row demand sets accordingly, typically can enclose and be located at die cavity periphery.In rear mold mold insert, due to product structure, after Mould center mold insert diameter is less, therefore can be to use the form of jet pipe cooling in annular water channel.Described annular water channel is in constantly flowing During, the exchange of cold and hot amount can be carried out, constantly to carry out required cooling.
Described front template top is provided with cooling well 13, is connected by pipeline, described well 13 between described well 13 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.
