Further, drainage baffle is all made of zirconium silicate with overflow brick ontology and is made.

Further, drain baffle with a thickness of 30-50mm；Nearest distance is glass to be prepared between two drainage baffles Glass basic width.

Compared with prior art, the utility model has technical effect beneficial below:

A kind of base plate glass overflow molding machine of the utility model, by the way that overflow brick ontology is arranged, on overflow brick ontology The drainage trough for draining glass metal is arranged in end, and overflow brick ontology lower end is V-structure, difference on the outside of the both ends of overflow brick ontology Equipped with a drainage baffle, drainage trough one end on overflow brick ontology is liquid inlet, the liquid inlet of drainage trough and overflow brick Glass metal conveying device input port connection, during making glass substrate forming, using being fixed at overflow brick ontology both ends Drainage baffle prevents glass metal along overflow brick ontology both ends extension, ensures that the accuracy of glass substrate production size, knot Structure is simple, without being accommodated by cooling aid mechanism, facilitates operation, structure is simple, reduces costs, and ensure that glass base The fluctuation and Forming Quality of plate ensure that production is more stable.

Further, drainage baffle is structure as a whole with overflow brick ontology, and drainage baffle is bonded with overflow brick body outer wall, It ensure that the stability that drainage baffle and overflow brick ontology are fixed.

Further, the other end is equipped with for glass metal in drainage trough to overflow brick ontology in the drainage trough of overflow brick ontology The branching block that two sides shunt shunts convenient for glass solution, prevents drainage trough memory from letting off more glass and is easy.

Detailed description of the invention

FIG. 1 is a schematic structural view of the utility model.

Wherein, 1, overflow brick ontology；2, drainage trough；3, baffle is drained；4, branching block；5, overflow brick glass metal conveying dress It sets；6, connecting tube.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing:

As shown in Figure 1, a kind of base plate glass overflow molding machine, including overflow brick ontology 1,1 upper end of overflow brick ontology are set There is the drainage trough 2 for draining glass metal, 1 lower end of overflow brick ontology is V-structure, difference on the outside of the both ends of overflow brick ontology 1 Equipped with a drainage baffle 3,2 one end of drainage trough on overflow brick ontology 1 is liquid inlet, the liquid inlet of drainage trough 2 and is overflow The connection of 5 input port of brick glass metal conveying device is flowed, the other end is equipped with branching block 4 in the drainage trough 2 of overflow brick ontology 1, is used for glass Glass liquid is shunted in drainage trough 2 to 1 two sides of overflow brick ontology；2 groove depth of drainage trough from 2 liquid inlet one end of drainage trough to the other end by Gradually reducing, drainage baffle 3 is structure as a whole with overflow brick ontology 1, and drainage baffle 3 is bonded with 1 outer wall of overflow brick ontology,
