Wherein: 1, cover half；2, dynamic model；3, positioning column；4, positioning plate；5, demoulding mechanism；6, sprue；7, workpiece to be added；
8, type chamber.
Specific embodiment
Below with reference to attached drawing, the utility model will be further described, it should be noted that the present embodiment is with this skill
Premised on art scheme, the detailed implementation method and specific operation process are given, but the protection scope of the utility model is not
It is limited to the present embodiment.
Fig. 1 is a kind of longitudinal section of the mold of school's tables and chairs bound edge injection molding machine of the embodiments of the present invention, such as Fig. 1
Shown, the structure of the utility model including hopper, the barrel communicated with hopper, the screw rod being rotatably dispose in barrel, is set to
Heater between screw rod and barrel, the cover half 1 for being set to barrel output end, the side dynamic model 2 and and dynamic model opposite with cover half 1
The connected demoulding mechanism 5 in 2 other sides, cover half 1 offer one end phase with sprue 6 in the position of 7 peripheral contact of workpiece to be added
Logical type chamber 8,6 other end of sprue are connected with barrel output end, are provided on dynamic model 2 for being clamped the flexible of workpiece 7 to be added
Positioning mechanism, the workpiece to be added 7 of the present embodiment are desktop or seat plate, and Telescopic positioning device includes surrounding workpiece 7 to be added
The location hole being opened on dynamic model 2 and the positioning column 3 for being arranged in positioning hole, the width of positioning column 3 are not more than the width of type chamber 8
