In order to overcome the deficiencies in the prior art, this utility model provides a kind of arc voice box casing extrusion die.
This utility model solves its technical problem and be the technical scheme is that
A kind of arc voice box casing extrusion die, it is characterized in that: include the die head being fixedly connected sequentially, middle module, front module and the forming hole of through above-mentioned parts, and this forming hole is bent into arc, described forming hole is provided with the core rod being bent into arc coordinated with it, described front module comprises upper mold section and female die, and the arc shell that the plastic material of fusing becomes bending by the extruding of core rod Yu molding hole wall is extruded.
Described forming hole includes the first die hole being positioned in die head, be positioned in middle module the second die hole, the 3rd die hole being positioned in front module.
One end of described first die hole is round nose, and the other end is tetragon end, and this tetragon is wherein arc relative to both sides.
Described core rod includes that profiled section and pan feeding section, described pan feeding section are positioned at the first die hole, and pan feeding section is taper, and the part that described profiled section is adjacent with pan feeding section is provided with some locating pieces, is provided with the locating slot mutually embedding with this locating piece in described second die hole.
The bottom surface of described female die is provided with kerve and side is provided with side channel, and described kerve is embedded with end insert, and described side channel is embedded with side insert, and the both sides of described side insert and end insert are equipped with convex edge.
Described front module is provided with and the retaining ring of front module threaded engagement.
The beneficial effects of the utility model are: this utility model includes the die head being fixedly connected sequentially, middle module, front module and the forming hole of through above-mentioned parts, and this forming hole is bent into arc, described forming hole is provided with the core rod being bent into arc coordinated with it, described front module comprises upper mold section and female die, the arc shell that the plastic material of fusing becomes bending by the extruding of core rod Yu molding hole wall is extruded, arc voice box casing can be extruded, to meet the requirements at the higher level of user by said structure.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is explosive view of the present utility model；
Fig. 2 is overall diagram of the present utility model；
Fig. 3 is cut-away view of the present utility model；
Fig. 4 is mold insert structure figure of the present utility model.
Detailed description of the invention
Referring to figs. 1 through Fig. 3, the utility model discloses a kind of arc voice box casing extrusion die, including the die head 1 being fixedly connected sequentially, middle module 2, front module 3 and the forming hole of through above-mentioned parts, and this forming hole is bent into arc, described forming hole is provided with the core rod 4 being bent into arc coordinated with it, described front module 3 comprises upper mold section 31 and female die 32, the arc shell that the plastic material of fusing becomes bending by the extruding of core rod 4 with molding hole wall is extruded, described forming hole includes the first die hole being positioned in die head 1, the second die hole being positioned in module 2, the 3rd die hole being positioned in front module 3, described core rod 4 includes profiled section and pan feeding section.
As shown in the figure, die head 1 flue, the end face of its big end has a ring flange, for being connected with middle module 2, die head 1 has the first die hole, one end of this first die hole is round nose, and the other end is tetragon end, and this tetragon is wherein arc relative to both sides, thus the first die hole is similar to the bellmouth orifice that a kind of cross section is tetragon, round nose area is little, tetragon end area is big, round nose is the end being connected with injection machine, the pan feeding section of core rod 4 is positioned at the first die hole, and pan feeding section is taper, the plastic material being easy to make the fusing entered by round nose by said structure keeps certain pressure even into the gap between core rod 4 and molding hole wall, thus form uniform thin walled shell.
The part that described profiled section is adjacent with pan feeding section is provided with some locating pieces 41, is provided with the locating slot mutually embedding with this locating piece 41 in described second die hole, could be fixed also and be formed between molding hole wall the clearance space of extrusion moulding by said structure core rod 4.
The bottom surface of described female die 32 is provided with kerve and side is provided with side channel, described kerve is embedded with end insert 5, described side channel is embedded with side insert 6, the both sides of described side insert 6 and end insert 5 are equipped with convex edge, convex edge can go out groove when molding at arc shell surface structure, and the groove that surrounds of the inner surface of convex edge and female die 32 may be constructed the chimb on arc shell surface, in order to process and the easily manufactured mode that insert must be used to assemble, it is impossible to once process on female die 32 or upper mold section 31.
As it can be seen, in order to be connected with cold true case, front module 3 is provided with and the retaining ring of front module 3 threaded engagement, by retaining ring, this extrusion die is locked together with cold true case.
A kind of arc voice box casing extrusion die above this utility model embodiment provided, it is described in detail, principle of the present utility model and embodiment are set forth by specific case used herein, and the explanation of above example is only intended to help to understand method of the present utility model and core concept thereof；Simultaneously for one of ordinary skill in the art, according to thought of the present utility model, the most all will change, in sum, this specification content should not be construed as restriction of the present utility model.
