The technical solution adopted for the present invention to solve the technical problems is:
A kind of curved pipe moulding mould special, it is characterized in that: include the forming hole of the die head being fixedly connected sequentially, middle module, front module and 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 being mated, described front module comprises upper mold section and female die, and the plastic material of fusing becomes the arc shell extrusion of bending by the extruding of core rod Yu molding hole wall.
Described forming hole includes the first die hole being arranged in die head, the second die hole being arranged in module, is arranged in the 3rd die hole of front module.
One end of described first die hole is round nose, and the other end is tetragon end, and the wherein relative both sides of this tetragon are arc.
Described core rod includes profiled section and pan feeding section, and described pan feeding section is 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 invention has the beneficial effects as follows: the present invention includes the forming hole of the die head being fixedly connected sequentially, middle module, front module and 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 being mated, described front module comprises upper mold section and female die, the plastic material of fusing becomes the arc shell extrusion of bending by the extruding of core rod Yu molding hole wall, arc voice box casing can be extruded, to meet the requirements at the higher level of user by said structure.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the explosive view of the present invention；
Fig. 2 is the overall diagram of the present invention；
Fig. 3 is the cut-away view of the present invention；
Fig. 4 is the mold insert structure figure of the present invention.
Detailed description of the invention
Referring to figs. 1 through Fig. 3, the invention discloses a kind of curved pipe moulding mould special, including the die head 1 being fixedly connected sequentially, middle module 2, the forming hole of front module 3 and 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 being mated, described front module 3 comprises upper mold section 31 and female die 32, the plastic material of fusing becomes the arc shell extrusion of bending by the extruding of core rod 4 with molding hole wall, described forming hole includes the first die hole being arranged in die head 1, it is arranged in the second die hole in module 2, it is arranged in the 3rd die hole of 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 the wherein relative both sides of this tetragon are arc, 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 forming 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 adopted 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 and cold true case are locked together.
A kind of curved pipe the moulding mould special above embodiment of the present invention provided, it is described in detail, principles of the invention and embodiment are set forth by specific case used herein, and the explanation of above example is only intended to help to understand method and the core concept thereof of the present invention；Simultaneously for one of ordinary skill in the art, according to the thought of the present invention, all will change in specific embodiments and applications, in sum, this specification content should not be construed as limitation of the present invention.
