Abstract
The invention discloses a soft sealing gate valve lost foam and a pouring method thereof. The soft sealing gate valve lost foam comprises a gate valve die, an ingate, a cross gate, a pouring hole and a connecting rod and is characterized in that the ingate is arranged on the gate valve die; the cross gate is arranged on one side of the ingate; the pouring hole is formed in the middle of the cross gate; and one end of the connecting rod is connected with the cross gate and the other end of the connecting rod is connected with the gate valve die. According to the invention, the ingate is arranged on one side of the gate valve die and the cross gate is arranged on one side of the ingate, so that the soft sealing gate valve lost foam can be uniformly poured in the pouring process, the phenomenon of shrinkage of a soft sealing gate valve is avoided and the qualified rate of the product is improved.
Description
Technical field
The present invention relates to a kind of pouring procedure of evaporative pattern, especially relate to a kind of soft sealing gate valve evaporative pattern and pouring procedure thereof.
Background technology
Existing soft sealing gate valve evaporative pattern, in process, is arranged on ingate the middle part of soft sealing gate valve evaporative pattern mostly, and cross gate rides on ingate, after cast, soft sealing gate valve is prone to the phenomenon of shrinkage cavity, easily produces defective work, has improved production cost.
Because existing soft sealing gate valve evaporative pattern is arranged on cross gate on ingate, when cast, soft sealing gate valve evaporative pattern is first poured into a mould from the part close to sprue gate, after part far away, pour into a mould, make soft sealing gate valve evaporative pattern integrated poured inhomogeneous, cause soft sealing gate valve finished product to occur shrinkage cavity, reduced end properties and qualification rate.
Summary of the invention
The object of the invention is to be prone to for existing soft sealing gate valve the defect that shrinkage cavity, product qualified rate are not high, a kind of simple and reasonable, soft sealing gate valve evaporative pattern and pouring procedure thereof that product qualified rate is high are provided, improve end properties, reduced production cost.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of soft sealing gate valve evaporative pattern, comprise gate valve mould, ingate, cross gate, plug hole and connecting rod, it is characterized in that: two width gate valve moulds are set on described soft sealing gate valve evaporative pattern, improved operating efficiency, described ingate is arranged on gate valve mould, described cross gate is arranged on a side of ingate, be convenient to the processing of soft sealing gate valve evaporative pattern, can make soft sealing gate valve evaporative pattern evenly pour into a mould simultaneously, avoid soft sealing gate valve finished product to occur the phenomenon of shrinkage cavity, improved end properties, described plug hole is arranged in the middle of cross gate, described connecting rod one end is connected with cross gate, the other end is connected with gate valve mould, both improved the stable degree of cross gate, also being convenient to soft sealing gate valve evaporative pattern can evenly pour into a mould when cast, improved the qualification rate of finished product.
Ingate on each described gate valve mould is 2.
Connecting rod on each described gate valve mould is 2.
A kind of pouring procedure of soft sealing gate valve evaporative pattern, it is characterized in that: adopt following steps: first, on gate valve mould, ingate is installed, cross gate is pasted in the same side of the ingate of two secondary gate valve moulds, plug hole is installed in the middle of cross gate, during cast, soft sealing gate valve evaporative pattern can wholely evenly be poured into a mould, reduced the defect rate of soft sealing gate valve finished product, improved end properties, on cross gate and gate valve mould, connecting rod is set, is assembled into soft sealing gate valve evaporative pattern; Then to soft sealing gate valve evaporative pattern sprayable refractory; After drying, bury vibration molding in dry quartz sand; Then under negative pressure, by plug hole, pour into a mould, soft sealing gate valve evaporative pattern produces gasification after running into hot molten metal, and molten metal occupies the position of soft sealing gate valve evaporative pattern, solidifies just finished product of cooling rear formation soft sealing gate valve; After polishing process, make soft sealing gate valve finished product.
Beneficial effect: the present invention is arranged on ingate one side of gate valve mould, and cross gate is arranged on a side of ingate can evenly be poured into a mould soft sealing gate valve evaporative pattern when cast, avoids soft sealing gate valve to occur the phenomenon of shrinkage cavity, has improved product percent of pass.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is right view of the present invention.
Fig. 3 is top view of the present invention.
In figure: 1. gate valve mould, 2. ingate, 3. cross gate, 4. plug hole, 5. connecting rod.
The specific embodiment
The part that the present invention does not relate to all prior art that maybe can adopt same as the prior art is realized.
