Abstract
The invention discloses a feed-head-free glass mold bottom casting method. The method comprises the steps that a middle cavity with a feed dead is arranged, the lower portion of the middle cavity is made communicated with the side walls of the tops of a plurality of molding casting cavities for a mold bottom through ingates, a casting channel is arranged to be made communicated with the middle cavity, alloy melt is cast in the casting channel, passes through the middle cavity and then flows into the molding casting cavities from the tops of the molding casting cavities at the same time through the ingates, casting is stopped when the alloy melt exceeds one half of the height of the feed dead, and the molding casting cavities are big-end-up step cylindrical cavities. According to the feed-head-free glass mold bottom casting method, the alloy usage amount can be effectively reduced, follow-up machining steps are omitted, the cost is reduced, and casting quality is improved.
Description
Technical field
The present invention relates to a kind of glass mold pouring procedure, particularly to one kind no rising head glass mold mould bottom pour mold note side
Method, belongs to glass mold production technical field.
Background technology
The mould bottom structure of glass mold is as shown in figure 1, generally including first round platform 1 being relatively large in diameter and being arranged at
Less second round platform 2 of diameter thereon, the first round platform 1 bottom surface is plane, and the upper surface of the second round platform 2 sets according to specific needs
It is set to plane or projection.Existing glass mold mould bottom pour mold injecting method, as shown in Fig. 2 running castings include molding mold cavity 3, becomes
The upper diameter of type mold cavity 3 is more than lower diameter, and in step-like, top is used for molding first round platform, and bottom is used for molding second
Round platform, ingate 4 entrance is arranged on lower sides, and ingate 4 bottom surface is flushed with molding mold cavity 3 bottom surface, the top of molding mold cavity 3
The rising head 5 being connected with molding mold cavity 3 is set.During cast, alloy molten solution flows into molding mold cavity bottom from bottom to top from ingate
Until alloy molten solution enters rising head and liquid level exceedes the injection stopping alloy molten solution during riser height half.The method subject matter
It is to need to arrange a rising head for making up the shrinkage cavity defect of the first round platform bottom surface for each molding mold cavity, so that alloy materials is increased
Many, it is simultaneously used for the presence of rising head, the first round platform bottom surface need to separately process, increase production cost.
Content of the invention
For problem of the prior art, the invention provides one kind no rising head glass mold mould bottom pour mold injecting method, solve the
Alloy materials are many simultaneously for one round platform bottom surface defect, the first round platform bottom surface need to individually process and surface quality of continuous castings defect more than ask
Topic.
Technical solution of the present invention is as follows: one kind no rising head glass mold mould bottom pour mold injecting method, including being provided with rising head
Intermediate cavity, described intermediate cavity bottom is connected by ingate with the top sidewall of the molding mold cavity at some mould bottoms, and setting cast is logical
Road is connected with described intermediate cavity, pours into a mould alloy molten solution, described alloy molten solution is poured by interior after intermediate cavity in described cast passage
If road flows into molding mold cavity from the top of dry forming mold cavity, when described alloy molten solution exceedes described riser height 1/2nd simultaneously
Stop cast, described molding mold cavity is up big and down small stepped cylindrical chamber.
Preferably, the quantity of the molding mold cavity at described mould bottom is 3.
Preferably, described intermediate cavity is identical with the length of the ingate of the molding mold cavity connection at some mould bottoms.
Preferably, cast step during other cast is also had to require supplementation with.
The advantage of technical scheme provided by the present invention is, each molding mold cavity original one rising head of setting is changed to
Multiple molding mold cavity share a rising head and carry out feeding, decrease alloy dosage, reduces cost；The top surface of molding mold cavity is not simultaneously
Set rising head again, that is, after mould bottom pour mold injection forming, bottom surface directly forms smooth flat, need not reprocess, further reduces cost；Inside pour
The sprue gate in road moves to top, and the riser feeding of the intermediate cavity connecting by ingate from molding mold cavity bottom, changes former
There are foundry goods cooling order, mould casting few surface defects.
Brief description
Fig. 1 is the mould bottom structure schematic diagram of glass mold.
Fig. 2 is running castings structural representation in prior art.
Fig. 3 is running castings structural representation of the present invention.
Fig. 4 is the aa cross section structure diagram of Fig. 3.
Fig. 5 is casting complete schematic diagram of the present invention.
Specific embodiment
With reference to embodiment, the invention will be further described, but not as a limitation of the invention.
Running castings such as Fig. 3 that no rising head glass mold mould bottom pour mold injecting method disclosed in the present embodiment is adopted, 4 institutes
Show, including upper mold 10 and lower mold 11, upper mold 10 and lower mold 11 are applied in combination.During the central authorities of wherein lower mold 11 are provided with
Between chamber 12, intermediate cavity 12 for bottom surface be in dome-type cylindrical cavity.Around intermediate cavity 12, multiple molding for the molding of mould bottom are set
Mold cavity 13, the present embodiment employs 3 molding mold cavity 13, and particular number can suitably adjust.Molding mold cavity 13 is up big and down small
Stepped cylindrical chamber, top sidewall is connected with intermediate cavity 12 by ingate 14.In order to ensure that multiple molding mold cavity 13 pour into a mould simultaneously,
Ingate 14 identical length connecting each molding mold cavity 13 is same.Intermediate cavity 12 is additionally provided with leads to for the cast pouring into a mould alloy molten solution
Road 15.When upper mold 10 is not combined with lower mold 11, molding mold cavity 13, ingate 14, intermediate cavity 12 and cast passage 15
Top surface is opening shape.The bottom surface of upper mold 10 is plane, arranges rising head 16 in the correspondence position of intermediate cavity 12.Upper mold 10
When combining with lower mold 11, molding mold cavity 13 and ingate 14 upper opening are closed by the bottom surface of upper mold 10, intermediate cavity 12
Combine connection with rising head 16.
Casting process as shown in figure 5, cast when alloy molten solution enter intermediate cavity 12 by pouring into a mould passage 15, be then passed through 3
Ingate 14 simultaneously enters 3 molding mold cavity 13, and flows down from molding mold cavity 13 top, when alloy molten solution gradually fills molding casting
During chamber 13, alloy molten solution initially enters rising head 16, and alloy molten solution stops cast when exceeding rising head 16 height 1/2nd, is cooled to
The runner that type, separating casting and ingate 14 are formed.
