Symmetric Composite forms cavity plate；The edge 21 of the oriented outside of half cavity plate 2 extension is set on the joint face 24 of half cavity plate 2；It is described
Bolt hole 22 is provided with edge 21, the bolt hole 22 is centrally located at center line O1 O2Close to the side of pressure pipe die cavity；
The center line O1 O2The perpendicular bisector of distance between cavity plate internal diameter is arrived for the outside of edge 21；Locking is installed on half cavity plate 2
Bolt, the bolt hole 22 of the clamping screw through two and half cavity plates 2 lock two and half cavity plates 2；The one end of punch-pin 1 insertion is recessed
Coordinate in mould with cavity plate, the other end is provided with flange 12, and the flange 12 is connected by bolt with cavity plate；The punch-pin 1 with it is recessed
Pressure pipe forming cavity 3 is formed between mould；Be provided with the end face of one end that the punch-pin 1 is provided with flange 12 connection pressure pipe into
The injecting hole 11 of die cavity 3.
During injection molding pressure pipe：
First two and half cavity plates 2 are combined to form cavity plate；Two and half cavity plates 2 are symmetrically placed, then by locking screw
Bolt passes through bolt hole 22 by two and half cavity plates, 2 locked formation cavity plate.Due to setting oriented half on the joint face 24 of half cavity plate 2
The edge 21 of the outside of cavity plate 2 extension；Bolt hole 22 is provided with the edge 21, the bolt hole 22 is located at the center line of edge 21
O1 O2 are close to the side of pressure pipe die cavity；Therefore when two fast half cavity plates 2 are locked by bolt, clamp force can be increased.
After cavity plate is completed, punch-pin 1 is inserted into cavity plate, while by bolt by the flange 12 and cavity plate of punch-pin 1
Connection；After mould is completed, stoste will be molded by injection machine pressure pipe shaping is injected into by the injecting hole 11 on punch-pin 1
In chamber 3, now the air in pressure pipe forming cavity 3 is discharged by steam vent 25；Then cooled down, when pressure pipe is molded
Afterwards, punch-pin 1 is dismantled；Finally two and half cavity plates 2 are split, so as to take out pressure pipe.Being repeated the above steps after taking-up can be with
Another batch of pressure pipe is produced.
It is total described, the firm pressure pipe mold of locked mode described in the utility model, due to the joint face 26 in half cavity plate 2
Edge 21 on bolt hole 22 is set, while bolt hole 22 is centrally located at center line O1 O2The side of close pressure pipe die cavity,
Therefore the coupling mechanism force of clamping screw can effectively be increased, so as to which larger clamp force can be provided using identical bolt.Cause
This can reduce the damage of bolt, extend the service life of bolt, reduce the requirement to clamping screw, while constant in clamp force
In the case of can reduce the quantity of clamping screw, so as to reduce cost.
In order to increase the sealing between cavity plate and punch-pin 2；The lower surface of the further flange 12 is provided with annular
