Description of the drawings
Fig. 1 is a kind of schematic cross-sectional view of the bound edge injection mold of tubular structural member of the utility model.
Fig. 2 is the schematic diagram after tubular structural member injection molding in the utility model.
Specific implementation mode
The utility model provides a kind of bound edge injection mold of tubular structural member.Below in conjunction with attached drawing to the utility model
Technical solution is described in detail, so that it is more readily understood and grasps.
A kind of bound edge injection mold of tubular structural member, as shown in Fig. 2, tubular structural member 1 includes circular body, circle is main
The bottom of body is equipped with step-like protrusion, and bound edge injection mold on tubular structural member 1 i.e. for being molded by packet as shown in Figure 2
Side 2, the bound edge play the protective effect to tubular structural member 1.
Specifically, as shown in Figure 1, bound edge injection mold along the direction at top to bottom be respectively equipped with push gum-filling mechanism 3,
Upper mold 4 and lower die 5, wherein lower die 5 is equipped at least one lower mode cavity 51 for carrying tubular structural member 1, and lower die 5
It is equipped with the dismounting through hole communicated with lower mode cavity 51, upper mold 4 is equipped with the press moulding mechanism 6 to match with lower mode cavity 51, so-called
Matching is that exponential quantity and position are consistent, and squeeze-film mechanism 6 includes injecting glue open cavity 61 and the pressure positioned at 61 bottom of injecting glue open cavity
The periphery of mould 62, pressing mold 62 is equipped with several injecting glue through-holes 63, and the opening direction of wherein injecting glue open cavity 61 pushes gum-filling mechanism 3,
It includes the glue injection part 31 to match with injecting glue open cavity 61, the glue injection part 31 position in injecting glue open cavity 61 to push gum-filling mechanism 3
It moves.
When injection molding state, tubular structural member 1 is set in lower mode cavity 51, and the bottom of pressing mold 62 compresses tubular structural member 1
Top, glue injection part 31 are located in injecting glue open cavity 61, and injecting glue through-hole 63 penetrates through injecting glue open cavity 61 and lower mode cavity 51, lower mode cavity
51, injection die cavities are formed between 1 three of pressing mold 62 and tubular structural member.
The realization principle and process of this case are described：
Tubular structural member 1 is placed into lower mode cavity 51 first, and adjusts position, then upper mold 4 and lower die 5 are closed
Mould pushes gum-filling mechanism 3 and presses to glue injection part 31 into injecting glue open cavity 61, proceeds by injecting glue, glue injection part 31 is fixed
The injection of glue amount, colloid enters along injecting glue through-hole 63 fills injection die cavities in lower mode cavity 51, after injecting glue, in injection die cavities
Colloid is formed by curing bound edge 2, then carries out tubular structural member dismounting, upper mold 4 and lower die 5 carry out a point mould, then pass through ejector
Structure passes through dismounting through hole 52 by bottom to top-direction, and tubular structural member 1 is ejected.Dismounting through hole 52 facilitates circular configuration
