Specific embodiment
Present invention discloses a kind of belt pulleys and helical gear product molding die successively to include as shown in figs 2-4
Upper mounted plate, front template 1, rear pattern plate 2, backing plate 3, ejector retainner plate 4 and bottom plate.It is provided with thimble 6 below the type chamber, it is described
The bottom of thimble 6 is connect with ejector retainner plate 4, is additionally provided with support block between the backing plate 3 and ejector retainner plate 4.When demoulding, the ejector retainner plate
4 drive thimble to push product movement.The component part is consistent with the prior art, therefore this will not be detailed here.
It is respectively arranged with mutually matched preceding mould mold insert 8 and rear mold mold insert in the front template 1 and rear pattern plate 2, before described
Type chamber is provided between mould mold insert and the rear mold mold insert.The type chamber includes under a belt pulley upper end and helical teeth with straight-tooth
End, the belt pulley upper end are placed in the top of helical teeth lower end, and the belt pulley upper end and the helical teeth lower end by connecting shaft
Coaxial, before the belt pulley upper end of type chamber is set in mould mold insert 8, the helical teeth lower end of type chamber is placed in rear mold mold insert.
In order to preferably make helical teeth lower end be demoulded in demoulding, ring gear edge is provided in the rear mold mold insert
Part 10 and mold insert briquetting 11, the ring gear mold insert 10 are engaged with the helical teeth lower end of the type chamber.The mold insert briquetting 11 is placed in tooth
The top of ring mold insert 10, and transmission lubrication component, the tooth are provided between the mold insert briquetting 11 and the ring gear mold insert 10
The rotation of ring mold insert 10 drives product stripping.
Specifically, the inner ring of the ring gear mold insert 10 is provided with helical teeth, the helical teeth is engaged with the helical teeth lower end of type chamber.
10 upper surface of ring gear mold insert offers an annular groove 15, is provided with ripple pearl screw in the bottom of the mold insert briquetting 11
12, the ripple pearl screw 12 is slided in groove 15, and is evenly equipped with graphite block 14 between the adjacent ripple pearl screw 12.It is described
Ripple pearl screw can also use other modes, such as the form of collision bead screw or other tightening steel balls.The graphite block can be with
It is replaced using other cup greases etc..
In principle, the groove also be can be set in mold insert briquetting bottom, be carried out still through ripple pearl screw and graphite
Lubrication rotation.
Since product is when pressure maintaining forms, temperature is higher in mold, in order to the temperature in better moulding and holding mold
Degree controls, and is provided with cooling system and temperature sensor 16 in the mold.When due to molding, forward and backward mould can generate heat,
For better monitoring temperature, one group of temperature sensor 16 is generally respectively arranged in forward and backward mould, each group is provided with two
It is a, and be oppositely arranged between every group of temperature sensor.
The cooling system is to be placed in the annular water channel 9 formed in forward and backward mould mold insert.The arrangement in the water route 9 can be into
Row demand is set accordingly, can generally be disposed around type chamber periphery.In rear mold mold insert, due to product structure, after
Mould center mold insert diameter is smaller, therefore form that can be cooling using jet pipe in annular water channel.The annular water channel is constantly flowing
In the process, the exchange of cold and hot amount can be carried out, constantly to carry out required cooling.
The front template top is provided with cooling well 13, is connected between the well 13 by pipeline, the well 13
The border of type chamber is distributed in more effectively to cool down to shaped article, is more advantageous to subsequent demoulding.Due to the present invention at
Temperature is higher when type, and in order to preferably guarantee service life, the bottom of the mold is provided with rear mold thermal insulation board 5, the rear mold
Thermal insulation board 5 is placed in below bottom plate.
Lower processing molding method of the invention described briefly below:
The processing method of a kind of belt pulley and helical gear product molding die, includes the following steps:
S1, casting, the forward and backward template of mold are molded to the original state for pouring beginning, and castable enters from note cast gate, passes through
Runner enters type chamber；
S2, molding, castable is in the intracavitary pressure maintaining molding of type；
S3, cooling carry out the cooling in mold by the cooling system in mold, and combination temperature sensor carries out temperature
Monitoring；
S4, die sinking, forward and backward template are opened after the cooling period, and preceding mould mold insert is detached from the belt pulley upper end of product, due to producing
The helical teeth lower end of product is placed in rear mold mold insert, waits demoulding.The casting of product, molding, with existing die casting molding side
Method is similar, due to the particularity of this product, so needing to carry out the improvement of technology in demoulding.
S5, demoulding, ejector retainner plate 6 push thimble to exert a force shaped article, and part power is applied on ring gear mold insert 10 by product,
During thimble above pushes away, driving ring gear mold insert 10 is rotated, due in the mold insert briquetting that is arranged on the ring gear mold insert
It is provided with graphite 14 and ripple pearl screw 15, graphite 14 plays the lubricating action between ring gear mold insert 10 and mold insert briquetting 11, and wave
Pearl screw 15 makes ring gear mold insert 10 in rotation, it is possible to reduce the rotational resistance of ring gear mold insert 10, so that is be well on is de-
Mould.
In the present invention in such a way that mold insert briquetting is in conjunction with ring gear mold insert, can be to avoid bearing be used, to avoid
Ranking is increased, cost is greatly reduced.Meanwhile cooling system will not be impacted, so that cooling is more abundant.Simultaneously as this
The die space area occupied of invention is smaller with respect to bearing depanning mode, so that primary plastic four products of mold, the type
Chamber, which is arranged in, to be poured around mouth, and processing efficiency is greatly improved.
Still there are many specific embodiment, all skills formed using equivalent replacement or equivalent transformation by the present invention
Art scheme, all falls within the scope of protection of present invention.
