The middle part for stating sprue is equipped with the discharge port being connected with the injection channel of upper mold, is distributed in the two sides of the discharge port several
Runner, the runner intersect vertically with the sprue, and the length of the runner of discharge port distal end is close greater than discharge port
The length of the runner at end；The exhaust passage being connected with adjacent forming cavity is equipped at the edge of the lower die.
It is equipped with heating device in the bottom of the lower die, is equipped with cooling water between the heating device and the lower die
Circulating line.
The runner both ends of discharge port distal end respectively extend to the inside of corresponding forming cavity, the runner two of discharge port proximal end
End extends to the edge of the isolation strip.
The utility model is used to produce the web plate of table tennis net, and simple production process is at low cost, easily controllable.This reality
It ensure that the web plate quality of injection molding is high with the special designing of novel flow channel, consistency of thickness and plate face is uniform, heating device and cooling
The fit applications of water circulating pipe, further improve production efficiency and product quality.

Specific embodiment
As depicted in figs. 1 and 2, the utility model structure include pedestal 8, heating device 9, cooling water circulating pipe 10, under
Mould 11 and the upper mold 12 matched with lower die 11 are set in lower die 11 there are two forming cavity 13, and each forming cavity 13 can be molded
The web plate of a table tennis net is formed, the specific structure of forming cavity 13 matches with the mesh-plate structure of corresponding table tennis net.
The table tennis net structure of the utility model injection molding is as shown in figure 3, including web plate 1 and being arranged in 1 both ends of web plate
Bracket 2, web plate 1 and bracket 2 are once molded by plastics respectively.Web plate 1 is in long strip-board shape, for horizontal in table tennis table
On table top, mesh is distributed on web plate 1, wherein the both ends of web plate 1 are respectively provided with the big mesh an of pentalpha, at two
There are many circular small mesh for distribution between big mesh.It is equipped with the reinforcement side 3 of prominent 1 plate face of web plate on the periphery of web plate 1, is being added
Strong 3 length directions when being provided on 3 along reinforcement extend the groove 4 of distribution, and the notch and 1 plate face of web plate of groove 4 are perpendicular, increase
The aesthetic feeling of table tennis net.Bracket 2 includes the connecting plate 5 for connecting table tennis table and the inserted link for connecting web plate 1；Even
Fishplate bar 5 intersects the dog-ear plate formed by facade and plane, is provided with mounting hole 7 in the facade of connecting plate 5, is used for connecting plate 5
It is fixed in the lateral edge of table tennis table, there are two mounting holes 7, is provided with the both ends of 5 facade of connecting plate, and mounting hole 7 is laterally long
Hole, hole is connect to increase it with table tennis table lateral edge bolt docks space.Upward insert is formed in the in-plane of connecting plate 5
Bar, inserted link are the cylindrical body with taper；It is each provided with downward opening jack at the both ends of web plate 1, inserted link is rotatably plugged in
The connection of web plate 1 and bracket 2 is realized in jack.
The forming cavity of the utility model and the shape of above-mentioned web plate 1 match, and are equipped with one under at the middle part of lower die 11
