According to the internal core-pulling mechanism, the sliding block slides towards the left in the sliding chute in the opening process of the upper mold plate and lower mold plate, so that the core pulling of plastic parts is completed. The internal core-pulling mechanism is simple and compact in structure, convenient to operate, reliable in movement, long in service life and suitable for popularization.
Description
[technical field]
The present invention relates to a kind of core-pulling mechanism of injection mold, more particularly relate to a kind of internal core-pulling mechanism of injection mold.
[background technology]
At present, plastic products are widely used in life, side core-pulling mechanism is also mechanism common in injection mold, and for the concave or convex structure on plastic, traditional injection moulding mould is all generally to adopt slanted pushing rod to realize the demoulding to loose core, but adopts this class formation will make mould structure very complicated, assembling trouble, and in production and application process, the wear extent of slanted pushing rod is large, has a strong impact on the service life of mould.
Therefore, the present invention formally produces based on this kind of situation.
[summary of the invention]
The present invention seeks to have overcome the deficiencies in the prior art, provide a kind of simple and compact for structure, reliable in action, easy and simple to handle, the injection mold internal core-pulling mechanism of long service life.
The present invention is achieved by the following technical solutions:
A kind of injection mold internal core-pulling mechanism, it is characterized in that: comprise cope match-plate pattern and can with the lower bolster of described cope match-plate pattern folding, described cope match-plate pattern is provided with patrix mold insert, described lower bolster is provided with counterdie mold insert, described counterdie mold insert is provided with chute, between described cope match-plate pattern and described lower bolster, be provided with when the two folding can be in described chute relative the two slide block horizontally slipping, described slide block and described counterdie mold insert and described patrix mold insert three surround plastic parts moulding chamber.
Injection mold internal core-pulling mechanism as above, is characterized in that: described slide block is provided with the slanting wedge hole of inclination, and described cope match-plate pattern is provided with the wedge that can insert described slanting wedge hole and promote to slide about described slide block.
Injection mold internal core-pulling mechanism as above, is characterized in that: described slide block keeps the retainer spring of location while making described slide block slide to die sinking final position away from being provided with between described counterdie mold insert one end and described lower bolster.
Injection mold internal core-pulling mechanism as above, is characterized in that: between described slide block and described lower bolster, be provided with the wearing plate sliding for described slide block thereon.
Injection mold internal core-pulling mechanism as above, is characterized in that: described slide block is provided with groove, and described retainer spring is located in described groove.
Injection mold internal core-pulling mechanism as above, it is characterized in that: described slide block is away from being provided with the limited post spacing to the sliding stroke of described slide block between described counterdie mold insert one end and described lower bolster, and the top, one end of described retainer spring is pressed on described limited post.
Compared with prior art, the present invention has the following advantages: the present invention is in the process of cope match-plate pattern and lower bolster die sinking, and slide block slides left in chute, thereby completes loosing core of plastic.The present invention is simple and compact for structure, easy to operate, reliable in action, long service life, be applicable to promoting.
[accompanying drawing explanation]
Fig. 1 is one of schematic diagram of the present invention;
Fig. 2 is two of schematic diagram of the present invention;
[specific embodiment]
Below in conjunction with accompanying drawing, the invention will be further described:
A kind of injection mold internal core-pulling mechanism, comprise cope match-plate pattern 1 and can with the lower bolster 2 of described cope match-plate pattern 1 folding, described cope match-plate pattern 1 is provided with patrix mold insert 3, described lower bolster 2 is provided with counterdie mold insert 4, described counterdie mold insert 4 is provided with chute 41, between described cope match-plate pattern 1 and described lower bolster 2, being provided with can be at interior relative the two slide block horizontally slipping 5 of described chute 41 when the two folding, and described slide block 5 surrounds plastic parts moulding chamber 6 with described counterdie mold insert 4 and described patrix mold insert 3 threes.In the process of cope match-plate pattern 1 and lower bolster 2 die sinkings, slide block 5 is in the interior slip of chute 41, and slide block 5 comes with plastic 11 disengagings in plastic parts moulding chamber 6, thereby complete, looses core.The present invention is simple and compact for structure, easy to operate, cost is low, reduce the requirement of injection moulding working condition.
Described slide block 5 is provided with the slanting wedge hole 51 of inclination, and described cope match-plate pattern 1 is provided with the slanting wedge hole 51 described in inserting and promotes the wedge 7 that slide described slide block 5 left and right.
Described slide block 5 keeps the retainer spring 8 of location while making described slide block 5 slide to die sinking final position away from being provided with between described counterdie mold insert 4 one end and described lower bolster 2.When die sinking completes, when slide block 5 slides into final position, script retainer spring 8 by compression extends and slide block 5 is withstood to location, has prevented the reverse slip of slide block 5.
Between described slide block 5 and described lower bolster 2, be provided with the wearing plate 9 sliding for described slide block 5 thereon.Wearing plate 9 can directly contact and the lower bolster 2 that weares and teares with lower bolster 2 by anti-limited slip block 5, after wearing plate 9 or slide block 5 wearing and tearing, only needs to change wearing plate 9 or slide block 5, and does not need to change the lower bolster 2 of larger, provides cost savings.
Described slide block 5 is provided with groove 52, and described retainer spring 8 is located in described groove 52.
Described slide block 5 is away from being provided with the limited post 10 spacing to the sliding stroke of described slide block 5 between described counterdie mold insert 4 one end and described lower bolster 2, and the top, one end of described retainer spring 8 is pressed on described limited post 10.
Operation principle of the present invention:
During die sinking, cope match-plate pattern 1, patrix mold insert 3 and wedge 7 move upward, wedge 7 promotes slide block 5 and slides left in the process making progress, slide block 5 slides left and looses core in chute 41, when the stroke sliding when slide block 5 is L, loosed core, wedge 7 departs from slanting wedge holes 51, now script retainer spring 8 by compression withstands location by slide block 5, prevents that it from sliding to the right.
During matched moulds, cope match-plate pattern 1, patrix mold insert 3 and wedge 7 move downward, and the slanting wedge hole 51 that wedge 7 inserts on slide block 5 promotes slide block 5 and slides to the right, and in this process, slide block 5, patrix mold insert 3 and counterdie mold insert 4 threes surround plastic parts moulding chamber 6 gradually.When matched moulds completes, slide block 5 leans on limited post 10 away from counterdie mold insert 4 one end, and the inclined-plane on the right of wedge 7 compresses the right tilted surface of slanting wedge hole 51, avoids slide block 5 to be subject to briquetting pressure and produces loosening.
