Detailed Description

As shown in fig. 1-5, the technical solution adopted by the present invention is: the utility model provides a double-colored injection mold of glasses leg, is equipped with rotary disk 2 including workstation 1 on the workstation 1, is equipped with at least one pair of lower mould 3 on the

rotary disk

2, 2 tops of rotary disk be equipped with first mould 4 and the second on mould 5, first mould 4 and the second lower mould 5 of going up can be with 3 compound dies of lower mould respectively, first mould 4 and the second on mould 5 be equipped with the feed port 41 to 3 feeding of lower mould respectively. In the above scheme, owing to set up at least one pair of lower mould 3, two pairs of last moulds, lower mould 3 sets up on rotary disk 2, first last mould 4 and lower mould 3 compound die earlier, during the compound die, the feed port 41 feeds and the shaping towards the mirror leg die cavity on the lower mould 3, after the completion, first last mould 4 leaves the lower mould, rotary disk 2 is rotatory, when lower mould 3 is in second last mould 5 below, mould 5 and lower mould 3 compound die on the second, and the feed port 41 of mould 5 is gone up to the second and transparent material is injected into towards the mirror leg die cavity and the shaping, through twice feeding compound die shaping, form double-colored mirror leg, through the above-mentioned setting, need not carry out many times technology concatenation, and is simple in process, and can reduce cost.

The lower die 3 comprises a bottom plate 31 and a lower die block 32 arranged above the bottom plate 31, a lower die plate 33 is arranged on the lower die block 32, a glasses leg cavity 34 is arranged on the lower die plate 33, a flow guide channel 35 communicated with the glasses leg cavity 34 is arranged on the lower die plate 33, and the feed hole 41 is communicated with the flow guide channel 35. After the first upper die 4 and the second upper die 5 are closed, the injection molding material in the feeding port 41 flows into the temple cavity 34 through the flow guide channel 35, and the temple injection molding is realized.

First last mould 4 and second go up mould 5 including last module 42 and locate the cope match-plate pattern 43 above last module 42, feed port 41 locate on cope match-plate pattern 43, be equipped with the charge-in pipeline 44 that switches on with feed port 41 and water conservancy diversion passageway 35 on cope match-plate pattern 43.
