The specific embodiment
Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The utility model proposes a kind of pitched roof mechanism,
Referring to Fig. 1-2, Fig. 1 is the structural representation of the utility model pitched roof mechanism; Fig. 2 is the structural representation of oblique top part in Fig. 1.
Pitched roof mechanism of the present utility model comprises rear mold 10, is provided with a storage tank (installed object in diagram in storage tank, cannot indicate) in the die joint of rear mold 10 upper ends, is provided with a blind hole 111 tiltedly leading in storage tank;
In above-mentioned storage tank, be also provided with the side of pushing away 12 of L-type, the side of pushing away 12 comprises connecting portion 121 and pushing part 122;
On the connecting portion 121 of the side of pushing away 12, be installed with a briquetting 13, and this briquetting 13 forms a clamp port 14 with pushing part 122;
Pitched roof mechanism of the present utility model also comprises an oblique top part 20, and this oblique top part 20 is F type, comprises brace 21, and the top 22 that is positioned at brace 21 tops, and be arranged on brace 21 on follower block 23; Wherein,
Above-mentioned follower block 23 is clamped in the clamp port 14 being comprised of briquetting 13 and pushing part 122; Above-mentioned top 22 attaches together in the back-off of processed product 30 for distributing; Above-mentioned brace 21 inserts in the blind hole 111 of the oblique guiding in storage tank.
Pitched roof mechanism of the present utility model also comprises that one is through to from rear mold 10 lower ends the push rod 15 being fixedly connected with the connecting portion 122 of the side of pushing away 12 in storage tank.
When die assembly, the tight lock of the insertion end first connecting portion of the above-mentioned side of pushing away 12 121 and push rod 15 being penetrated in rear mold couples together; Again the brace of oblique top part 20 21 is inserted in storage tank in the blind hole 111 of oblique guiding, makes the follower block 23 of oblique top part 20 be close to the pushing part 122 of the side of pushing away 12; Finally with briquetting 13, push down follower block 23 again, briquetting 13 is clamped in follower block 23 in clamp port 14 with pushing part 122 formation clamp ports 14; And briquetting 13 is tightly locked on the connecting portion 121 of the side of pushing away 12.Also there is gap in confirmable the drawing between above-mentioned follower block 23 and clamp port 14 of function according to pitched roof mechanism in mould, because brace 21 is during along blind hole 111 demoulding of oblique guiding, distance between meeting and the side of pushing away 12 widens, follower block 23 must can be slided along opening direction clamp port 14 is interior, so must guarantee that follower block 23 can not be stuck in clamp port 14, need to leave for the gap of sliding, guarantee follower block 23 smooth-going slip and not rocking in clamp port 14.
With further reference to Fig. 3, schematic diagram when Fig. 3 is the demoulding of the utility model pitched roof mechanism.In the process of the demoulding, push rod 15 moves upward under the driving of mould ejector plate, drives the side of pushing away 12 and briquetting 13 to move upward; Because the follower block 23 of oblique top part 20 is clamped between briquetting 13 and the side of pushing away 12, so drive follower block 23 to move upward; But again because the brace 21 of oblique top part 20 be subject to tiltedly the to lead guiding of blind hole 111 limits, so oblique top part 20 can only move obliquely along the oblique guide direction of blind hole 111; In the process of motion, there is lateral displacement, so come directly towards 22, can slowly in the back-off of processed product 30, deviate from, complete and loose core.
Adopt above-mentioned pitched roof mechanism of the present utility model, by existing, directly run through the leptosomatic oblique top that in whole rear mold and die cavity, product dispensation attaches together and split into above-mentioned push rod 15, the side of pushing away 12, briquetting 13, oblique top part 20 these four parts, oblique top part 20 relies on the side of pushing away 12 to promote, the length of oblique top part 20 is shortened greatly, avoid injection moulding process and because of elongated, the undercapacity of oblique top part 20, occur the problem of fracture, oblique top takes up room little simultaneously, do not need tilted footstock, what can make that mould does is compacter, and cost is lower.
Further, in the above-described embodiment, the shape of oblique top part 20 is F type, top 22 and follower block 23 all arrange the same side of brace 21, but of the present utility model being not limited thereto, top 22 and follower block 23 also can be located at respectively the both sides of brace 21, do not affect the ejecting function of above-mentioned oblique top part 20.As long as can guarantee that oblique top part 20 comprises one for the upwards thrust of the side of pushing away 12 is changed into the parts of oblique top part 20 ejecting forces, the parts that the oblique guiding parts of an oblique generation lateral displacement and attaches together with the barb distribution for the treatment of demoulding product 30 all can; The utility model such as shape are circumscribed not.
Particularly, above-mentioned briquetting 13 separates with the side of pushing away 12, is easy for installation during for die assembly, and certainly, briquetting 13 also can be designed to as a whole with the side of pushing away 12; During installation, first the follower block of above-mentioned oblique top part 20 23 is inserted in the clamp port 14 that briquetting 13 and the side's of pushing away 12 integral body have, and then the brace of oblique top part 20 21 is inserted in the blind hole 111 tiltedly leading, finally, by being through to insertion end and the briquetting 13 whole tight locks in the side of pushing away 12 of the push rod 15 in rear mold 10, can complete assembling.But this briquetting 13 is with the side's of pushing away 12 integral body when assembling, and it is convenient while separating with the side of pushing away 12 not as above-mentioned briquetting 13, to assemble.
Particularly, in the above-described embodiment, between above-mentioned briquetting 13 and the connecting portion 121 of the side of pushing away 12, by screw, tightly lock, between the insertion end of push rod 15 and the connecting portion of the side of pushing away 121, also adopt screw to be fixedly connected with; With screwdriver, tighten, easy accessibility, connects closely.
Further, in the above-described embodiment, come directly towards 22 and be provided with recess 221, come directly towards 221 and by this recess 221 and the barb for the treatment of demoulding product 30, hook to close to realize distributing and attach together.
The utility model also further proposes a kind of injection mold, comprises above-mentioned pitched roof mechanism, and pitched roof mechanism can be with reference to the pitched roof mechanism described in above-described embodiment.
Adopt the injection mold with above-mentioned pitched roof mechanism of the present utility model, by existing, directly run through the leptosomatic oblique top that in whole rear mold and die cavity, product dispensation attaches together and split into above-mentioned push rod 15, the side of pushing away 12, briquetting 13, oblique top part 20 these four parts, oblique top part 20 relies on the side of pushing away 12 to promote, the length of oblique top part 20 is shortened greatly, avoid injection moulding process and because of elongated, the undercapacity of oblique top part 20, occur the problem of fracture, oblique top takes up room little simultaneously, do not need tilted footstock, what can make that mould does is compacter, and cost is lower.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
