Abstract
The invention relates to a gate insert mechanism which is applied to an overlap gate or a side gate of a mould and comprises a thimble, a flat top and an insert, wherein the thimble is arranged in a male template, and one end of the thimble contacts a flow passage; the flat top is arranged in the male template, one end of the flat top contacts a product, and one side is aligned with one end of the product; and the insert is arranged in a male mould core, one side contacts the flat top, a round hole is arranged at one end of the insert, the gate is penetrated through the round hole, and one side of the round hole is aligned with one end of the gate. The round hole on the insert is added to the gate insert mechanism of the invention, so that the gate insert mechanism can realize the purpose of gate self-cutting in the mould to realize automation production and reduce subsequent processing.
Description
[technical field]
The present invention about a kind of hidden type gate insert mechanism, hidden type gate insert mechanism of particularly autotomying in a kind of mould.
[background technology]
Have spot pouring mouth and tunnel gate can realize mould ingate in mould to autotomy, and overlap joint and side gate can only be processed by the outer aft-loaded airfoil of mould, cannot realize automated production.
Fig. 1 illustrates the sectional view that existing cast gate enters clamp mechanism matched moulds state.
Refer to Fig. 1, this cast gate enters clamp mechanism, and be applied in a mould overlap joint and side gate, this cast gate enters clamp mechanism and comprises:
One thimble 12, it is located in male template 110, and this thimble 12 one end contacts with runner 11;
One flat top 14, it is located in male template 110, and this one end, flat top 14 contacts with product 13.
During die sinking, male template 110 and caster 120 are separated from each other, thimble 12 promotes runner 11 and product 13 together with flat top 14 simultaneously, when moving to certain position, above-mentioned runner 11 is taken off in the lump with product 13, because this existing gate mechanism will cannot realize automatically cutting off in mould, manual instrument will so just be needed cast gate 111 and product 13 to be separated.
In view of this, be necessary in fact to develop a kind of novel gate mechanism, break the prior art structure of cutting cast gate, solve existing gate mechanism and can not realize the object that mould ingate autotomys, to realize automated production, reduce with aft-loaded airfoil.
[summary of the invention]
Therefore, the object of the present invention is to provide a kind of novel cast gate to enter clamp mechanism, enter to realize cast gate the object that clamp mechanism can autotomy at mould ingate.
For reaching above-mentioned purpose, cast gate of the present invention enters clamp mechanism, and in the overlap joint being applied to a mould or side gate, this cast gate enters clamp mechanism and comprises:
One thimble, it is located in male template, and this thimble one end contacts with runner;
One flat top, it is located in male template, and this one end, flat top contacts with product and side and product one end align;
One enters son, and it is located in male die core, and side contacts with above-mentioned flat top, and this enters sub-one end and is provided with a circular hole, and above-mentioned cast gate penetrates this circular hole, and one of this circular hole side and cast gate one end align.
Compared to prior art, cast gate of the present invention enters clamp mechanism and adds a circular hole on son, cast gate can be made to enter clamp mechanism realize the object that mould ingate autotomys, to realize automated production, reduce with aft-loaded airfoil by this circular hole.
[accompanying drawing explanation]
Fig. 1 illustrates the sectional view that existing cast gate enters clamp mechanism matched moulds state.
Fig. 2 illustrates the sectional view that cast gate of the present invention enters clamp mechanism matched moulds state.
Fig. 3 illustrates the sectional view that cast gate of the present invention enters clamp mechanism die opening state.
Fig. 4 illustrates cast gate of the present invention and enters in clamp mechanism the structural representation entering son.
[detailed description of the invention]
Refer to Fig. 2, Fig. 3, Fig. 4, it be respectively the sectional view that cast gate of the present invention enters the sectional view of clamp mechanism matched moulds state, cast gate of the present invention enters clamp mechanism die opening state, cast gate of the present invention enter in clamp mechanism enter son structural representation.
Cast gate of the present invention enters clamp mechanism, and in the overlap joint being applied to a mould and side gate, this cast gate enters clamp mechanism and comprises:
One thimble 22, it is located in male template 210, and this thimble 22 one end contacts with runner 21;
One flat top 24, it is located in male template 210, and this one end, flat top 24 contacts with product 23 and side and the said goods 23 one end align;
One enters son 25, it is located in male die core 2101, this enters sub 25 one end and is provided with a circular hole 251, above-mentioned cast gate 211 penetrates this circular hole 251, and one of this circular hole 251 side and cast gate 211 one end align, this enters sub 25 sides and contacts with above-mentioned flat top 24, and this one end entering son 25 contact caster 220 is placed in groove 2201.
In the present embodiment, during die sinking, male template 210 and caster 220 are separated from each other, thimble 22 promotes runner 21 and product 23 together with flat top 24 simultaneously, because entering son, to be fixed on male template 210 motionless, and flat top 24 with enter son 25 and contact and define good shearing force, flat like this top 24 with enter son 25 and when doing relative motion, cast gate 211 cut off, when after the connection cutting off product 23 and cast gate 211, thimble 22 continues to promote runner 21, because the cast gate 211 self-temperature height being placed in sub 25 circular holes 251 is yielding, cast gate 211 is caused to depart from circular hole 251 along with after the promotion distortion of thimble 22, thus achieve the object that mould ingate autotomys.
