Specific embodiment
It is former to structure of the present invention below in conjunction with specific embodiment and accompanying drawing for the ease of the understanding of those skilled in the art
Reason is further described in detail：
As shown in accompanying drawing 1-10, a kind of double-color mold, including the first front die component 1, the second front die component 2 and back die component 3, the
One front die component 1 includes the first front template 11 and the first front mould 12 being installed on the first front template 11, and the second front die component 2 is wrapped
The second front template 21 and the second front mould 22 being installed on the second front template 21 are included, back die component 3 includes rear pattern plate 31, is installed on
Rear mold 32 and line position sliding block 33 on rear pattern plate 31, line position sliding block 33 are slidably connected with rear pattern plate 31, pacify on line position sliding block 33
Equipped with core pulling 34；Left and right two ends are symmetrically installed with elastic mechanism 4, elastic mechanism 4 and line position sliding block on the inclined-plane of line position sliding block 33
Oblique chute 40 is formed between 33.
In the present embodiment, the lateral surface of line position sliding block 33 is inclined-plane, and the side of the first front template 11 is provided with and line position sliding block 33
The drive block 13 of matching, the width of drive block 13 is less than distance between the inner of two oblique chute 40, as shown in accompanying drawing 1,9；When first
When front die component 1 works, drive block 13 is moved downward with the first front template 11, during the first front mould 12 and the matched moulds of rear mold 32,
Drive block 13 drives line position sliding block 33 to slide inside by the cooperation with the inclined-plane of line position sliding block 33, i.e., drive block 13 is acted directly on
On the inclined-plane of line position sliding block 33, after line position sliding block 33 is slided in place, line position sliding block 33 pushes down line position sliding block 33, then, injection machine note
Glue, completes first time injection molding, as shown in Figure 2；After the completion of being molded for the first time, the first front mould 12 leaves, due to drive block
13 and line position sliding block 33 be face contact, and the drive block 13 and elastic mechanism 4 presence is not connected, therefore, drive block 13 with
First motion upwards of front template 11, the holding position of line position sliding block 33 is motionless, as shown in Figure 3.
As shown in accompanying drawing 7-8, the elastic mechanism 4 includes slide bar 41 in, is connected to the outer slide 42 in the outside of interior slide bar 41
With spring 43, sideslip groove 331 is provided with the inclined-plane of line position sliding block 33, interior slide bar 41 is horizontally installed in sideslip groove 331；In order to protect
Slide bar 41 is smoothly slided in sideslip groove 331 in card, interior slide bar short slot 411 is provided with the front end outer side of interior slide bar 41, in interior slide bar
A spacing briquetting 5 is provided with short slot 411, spacing briquetting 5 is fixedly connected with line position sliding block 33；And the interior rear end of slide bar 41 extends
In the corresponding sideslip groove 411 of protuberance 332, under the collective effect of spacing briquetting 5 and protuberance 332, interior slide bar 41 is in line position
The bevel direction of sliding block 33 is without departing from sideslip groove 331.Extend at the inclined-plane two ends of line position sliding block 33 and be provided with protuberance 332, spring 43
Between outer slide 42 and the inner side of protuberance 332.Here, interior slide bar 41 and outer slide 42 are structure as a whole, protuberance 332 with
Line position sliding block 33 is also structure as a whole, and both facilitates processing and manufacturing, and the connection reliability of elastic mechanism 4 and line position sliding block 33 is ensured again
Property, and the reliability for ensureing the movement of elastic mechanism 4；When two outer slides 42 are extruded by external force, the compression spring 43 of outer slide 42,
Interior slide bar 41 and outer slide 42 are then displaced outwardly together.
In the present embodiment, outer slide short slot is provided with the leading inside of outer slide 42, outside outer slide short slot and line position sliding block 33
Side forms oblique chute 40, is provided with the side of the second front template 21 and detaches block 23, detaches the installation site and drive block of block 23
13 installation site correspondence, detach the bottom width of block 23 and be slightly less than distance between the outer end of two oblique chute 40, detach the top of block 23 and
Middle part width is all higher than distance between the outer end of two oblique chute 40, in ensureing that detaching block 23 can smoothly insert oblique chute 40, detaches
Block 23 is slidably matched with the clamping of oblique chute 40.
When rear mold 2 is rotated carries out second injection moulding, as shown in Figure 4；Detach block 23 with the second front template 21 to
During lower motion, the second front mould 22 and the matched moulds of rear mold 32, detach during the bottom of block 23 first inserts oblique chute 40, detach block 23 under
During row, detach the top of block 23 and detach the middle part of block 23 extruding outer slide 42, compression spring, interior slide bar 41 and outer slide 42 1
Rise and be displaced outwardly, elastic mechanism 4 simultaneously gives and detaches the one kind of block 23 and inside contract power, detach block 23 it is descending in place after, injection machine injecting glue is complete
Into second injection molding, as shown in Figure 5；After the completion of second is molded, die sinking action is carried out, detach block 23 with the second front mould
Plate 21 is moved upwards, detaches block 23 during up, drives elastic mechanism 4 to be displaced outwardly, and elastic mechanism 4 then drives line position to slide
Block 33 outwards makees core pulling action, detach block 23 it is up in place after, the core pulling of line position sliding block 33 action is also then completed.
Reasonable in design of the present invention, simplicity, low cost, without carrying out core pulling using hydraulic structure, by normal die sinking
Action is capable of achieving core pulling action, and mould is reliable, using, safeguard very convenient.
Above-described embodiment is the preferred scheme that the present invention is realized, and non-limiting exhaustion, and the present invention is also under same idea
There can be other variations, it is necessary to explanation, any obvious on the premise of inventive concept of the present invention is not departed from
Replace within the scope of the present invention.
