Abstract
The invention relates to an injection mold with a multidirectional internal core-pulling mechanism. The injection mold comprises a movable mold plate and a movable mold core, wherein a slider is embedded into the movable mold core; at least one lifter is embedded into the slider through an oblique guide rail groove; the tail of each lifter is slidably connected with a lifter push rod; and a T-shaped stretching end at the tail of the slider penetrates through a slider guide block and is embedded into a T-shaped groove obliquely formed on an oil cylinder connecting guide block. The defect that the common core-pulling mechanism cannot be well separated from button positions which are intensively arranged in multiple directions is overcome, the injection mold has a simple structure, the problem that the normal injection molding production of a product cannot be realized is solved, the cost of mold development, injection molding production and product assembly which are caused by changing a product structure and an assembly relationship is saved, and the mechanism moves reliably and is convenient to maintain.
Description
Technical field
The present invention relates to technical field of mold, especially a kind of injection mold with multi-direction internal core-pulling mechanism.
Background technology
In known technical field, especially for the automobile injection mold, because the restriction of the conditions such as the specific (special) requirements of Product Assembly and locus exists some button bits not realize loosing core along regular depanning direction, such as intensive multi-direction button bit of arranging, if there is not reliable and stable mould emptier this moment, then need to change product structure or assembly relation solves, do like this and can produce following shortcoming: (1) cost is high, change product structure or assembly relation, need to increase the development cost of mould, also need to change the assembly relation of product, increased production cost; (2) affect assembly reliability, the button bit assembly relation of change product will inevitably affect the with it reliability of Assembly part, the whole assembling of impact effect.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of injection mold that can adapt to multi-direction densely arranged button bit is provided.
The technical solution adopted for the present invention to solve the technical problems is: the injection mold with multi-direction internal core-pulling mechanism, comprise moving platen and be installed in moving-mould-core on the moving platen, oil cylinder connects guide pad and is connected the oil cylinder that the afterbody of guide pad is fixedly connected with oil cylinder, in described moving-mould-core, be inlaid with slide block, in described slide block, by the embedding of slant rail groove at least one oblique top is installed, the afterbody of described oblique top all slidely connects the oblique top push rod, sidewall at described slide block is provided with oblique top push rod chute, on described moving-mould-core and the position of being close to the afterbody of the afterbody of slide block and oblique top push rod be installed with SLIDE GUIDE, the afterbody of described slide block has the T-shaped end of stretching out, the stem that described oil cylinder connects guide pad has the T-shaped groove that is obliquely installed, and the afterbody of described slide block T-shaped stretched out the end and passed SLIDE GUIDE and embed and be installed on oil cylinder and connect in the T-shaped groove that is obliquely installed on the guide pad.
Further, as a kind of concrete form, the oil cylinder described in the present invention connects guide pad and is fixedly connected with the end of stretching out of oil cylinder by the T-shaped groove that is arranged on oil cylinder connection guide pad afterbody.
Further, for can adapt to long Core-pulling distance from, the present invention on described moving platen and be positioned at the afterbody place that oil cylinder connects guide pad and be installed with extension block.
The invention has the beneficial effects as follows: the shortcoming that the present invention can avoid common core-pulling mechanism can't better deviate from button bit in the face of intensive multi-direction button bit of arranging the time, simultaneously simple in structure, realize the demoulding of a plurality of directions by pulling mechanism in middle increase by one cover of loosing core, this programme has not only reduced die cost, and adopt this multi-direction internal core-pulling mechanism to solve goods and can't realize the problem that normal injection moulding is produced, save change product structure and assembly relation and caused mould development, the cost of injection moulding production and goods assembling, mechanism kinematic is reliable, easy to maintenance simultaneously.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.

The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
Such as Fig. 1, Fig. 2, Fig. 3 and the present invention shown in Figure 4 have a kind of embodiment of the injection mold of multi-direction internal core-pulling mechanism, comprise moving platen 1 and be installed in moving-mould-core 2 on the moving platen 1, oil cylinder connects guide pad 6 and is connected the oil cylinder 7 that the afterbody of guide pad 6 is fixedly connected with oil cylinder, in moving-mould-core 2, be inlaid with slide block 3, in slide block 3, be equipped with four for the oblique top 4 of the button bit of different directions by slant rail groove 3-1 embedding, the afterbody of described oblique top 4 all slidely connects oblique top push rod 4-1, sidewall at slide block 3 is provided with oblique top push rod chute 3-2, on moving-mould-core 2 and the position of being close to the afterbody of the afterbody of slide block 3 and oblique top push rod 4-1 be installed with SLIDE GUIDE 5, the afterbody of slide block 3 also has the T-shaped end 3-3 that stretches out, the stem that oil cylinder connects guide pad 6 has the T-shaped groove 6-1 that is obliquely installed, and the afterbody of slide block 3 T-shaped stretched out end 3-3 and passed SLIDE GUIDE 5 and embed and be installed on oil cylinder and connect in the T-shaped groove 6-1 that is obliquely installed on the guide pad 6, above-mentioned oil cylinder connects guide pad 6 and is fixedly connected with the end of stretching out of oil cylinder 7 by the T-shaped groove that is arranged on oil cylinder connection guide pad 6 afterbodys, for adapt to long Core-pulling distance from and avoid increasing the size of unnecessary moving platen, on moving platen 1 and be positioned at the afterbody place that oil cylinder connects guide pad 6 and be installed with extension block 8.
Mould is after arriving die sinking position, oil cylinder 7 resets, drive oil cylinder connection guide pad 6 and outwards slide, slide block 3 moves downward under tilting T-shaped groove 6-1 and SLIDE GUIDE 5 actings in conjunction simultaneously, owing to be slidingly connected by slant rail groove 3-1 and oblique top 4 in the slide block 3, so when slide block 3 down moves, cooperate oblique top push rod 4-1, slide block 3 will drive oblique top 4 oblique ejecting, the smooth demoulding of product, this moment, oblique top push rod chute 3-2 played the effect of dodging oblique top push rod 4-1.
Just the specific embodiment of the present invention of describing in the above specification, various not illustrating is construed as limiting flesh and blood of the present invention, the person of an ordinary skill in the technical field after having read specification can to before the described specific embodiment make an amendment or be out of shape, and do not deviate from essence of an invention and scope.
