Specific implementation
[0027] In order to make the technical personnel of the prior art better understand the technical scheme of the utility model, the utility model will be further introduced in detail below in conjunction with the drawings.
[0028] The utility model provides a kind of steering column decorative cover lower bottom mould as shown in Figures 1-6 Including:
[0029] Upper die 2 and lower die 3, upper die 2 is located above lower die 3, and the top side of lower die 3 is provided with decorative cover lower bottom cavity 8;Based on this, decorative cover lower bottom part can be quickly injection molded and produced by decorative cover lower bottom cavity 8.
[0030] The top end of upper die 2 is provided with die seat top plate 1, and the middle part of die seat top plate 1 is provided with injection port 7;
[0031] Further, the top of die seat top plate 1 is provided with mounting seat above injection port 7, and the side wall of mounting seat is provided with a plurality of connecting holes. Based on this, mounting seat can be connected with injection molding machine to facilitate installation and use.
[0032] The bottom end of lower die 3 is provided with die seat bottom plate 4;The top four ends of die seat top plate 1 and the bottom four ends of die seat bottom plate 4 are provided with recesses, and lifting ring 6 can be detachably connected in recess. The mold can be lifted and moved by lifting ring 6, and lifting ring 6 can be connected by screwing, which is convenient for disassembly and installation.
[0033] The sealing mechanism includes sealing channels 9 symmetrically opened at both ends inside the mold base top plate 1. The sealing channels 9 are connected to the injection port 7. The sealing channel 9 has a cavity 15 at one end relative to the injection port 7. The cavity 15 is rotatably connected to a threaded column 14 through a bearing. A threaded tube 11 is installed at one end of the threaded column 14, and a fixing rod 10 is connected to the other end of the threaded column 14. One end of the threaded tube 11 extends into the sealing channel 9 and is movably connected to a blocking block 12 through a bearing. One end of the fixing rod 10 extends out of the mold base top plate 1 and is connected to a rotating handle 5.
[0034] When the device is idle, the operator can simultaneously rotate the handles 5 on both sides of the mold base top plate 1, so that the handles 5 drive the threaded column 14 to rotate in the cavity 15 through the fixed rod 10. Then the threaded column 14 can drive the threaded tube 11 to move, so that the threaded tube 11 drives the block 12 to slide in the sealing channel 9. Then the two block 12 can approach each other and merge, so that the channel of the injection port 7 can be completely blocked, thereby effectively preventing the entry of impurities such as rainwater and dust, and greatly ensuring the quality of products produced in subsequent injection molding.
[0035] Furthermore, when in use, rotating the handle 5 in the opposite direction will move the two blocking blocks 12 away and open the injection port 7, allowing the device to be used normally.
[0036] The threaded tube 11 is symmetrically provided with guide bars 13 at one end relative to the plug 12, and guide grooves 16 matching the guide bars 13 are provided on both sides of the inner wall of the cavity 15.
[0037] The guide bar 13 and the guide groove 16 can form a support and limiting assembly. The threaded tube 11 can move along the guide groove 16 through the guide bar 13. Under the action of this structure, the threaded tube 11 can be effectively supported and limited, thereby preventing the threaded tube 11 from rotating or deviating, and thus greatly ensuring the stability of the block 12 when it moves.
[0038] The outer wall of the handle 5 is provided with multiple raised ribs arranged in a ring. The raised ribs form an anti-slip textured structure to facilitate better rotation of the handle 5.
[0039] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
