Fruit is more preferable；There is provided sealing structure, effectively blocks the gap between upper and lower mould, when upper mould, which moves to, to be bonded with lower mould, melting
Plastics will not be spilt from the gap of upper and lower mould, ensure the flush edge of workpiece being processed.
Further, the axis of the injection channel and the center line of the heating chamber are on same straight line；Ensure injection
The outer surface of passage is equal with the distance of heating tube, and injection channel is heated evenly, and ensures that plastics will not be cold in injection channel
But.
Further, the sealing structure is to be upwardly extended by the injection cavity wall and formed an annular convex, it is described on
Mould is provided with the annular groove being engaged with the annular convex；When upper mould, which moves to, to be bonded with lower mould, annular convex is inserted into annular groove
Interior, sealing between the two coordinates, and effectively prevents the plastics of melting from being spilt from the gap of upper and lower mould.
Preferably, the annular convex is provided with least one circle seal bead, and the annular groove is provided with and the seal bead
The seal groove being engaged；There is provided seal bead, reduces the contact area between annular convex and annular groove, so as to strengthen between the two
Pressure, sealing effectiveness is more preferable.
Preferably, also including a workpiece movement device, the workpiece movement device includes support, the rail on support
Road, can be in the transfer arm of front and rear reciprocating action on track and the displacement drive for driving track fore-aft motion on support
Part；During the track forward motion, the front end of the track extends the injection molding cavity top position；Can by the fore-aft motion of track
So that track is extended to above injection molding cavity, so that transfer arm is moved to injection molding cavity position and the work in it is taken out, automation is realized
Operation；And track only forward motion when extend above injection molding cavity, in injection moulding process, track can backward act and then leave injection
Above chamber, moving down for upper mould will not be caused to stop, ensure being normally carried out for injection operation.
In summary, the utility model has advantages below：During injection, the heating tube in heating chamber is persistently right
The plastics of melting in injection channel are heated, and are effectively prevented the plastics of melting from being cooled down in injection channel, will not be caused to note
Mould the blocking of passage；More preferable by casting the heat transfer effect between heating tube and upper mould, heating effect is more preferable；It is provided with
Sealing structure, the gap between upper and lower mould is effectively blocked, when upper mould, which moves to, to be bonded with lower mould, the plastics of melting will not be from
Spilt in the gap of upper and lower mould, ensure the flush edge of workpiece being processed.
