Utility model content
The purpose of this utility model is to solve the problem of prior art, and a kind of exhaust apparatus for injection mold is provided, and effectively solves the tired gas problem of mould, improve production efficiency and product quality by exhaust apparatus.
For reaching above-mentioned purpose, the utility model adopts following technical scheme:
For an exhaust apparatus for injection mold, the embedding piece groove that this mould comprises mold insert and is opened in template and embeds for mold insert; Between described embedding piece groove and mold insert, be provided with an exhaust apparatus, it comprises the air discharge duct that is arranged at the exhaust passage in embedding piece groove and is opened in mold insert bottom; Wherein, between every adjacent two mold inserts, have a gap, described gap is communicated with respectively air discharge duct with exhaust passage.
Further, the corresponding air discharge duct end positions in described exhaust passage is offered downwards and is communicated with template lateral wall.
Further, be also provided with a sealed groove for sealing in embedding piece groove, it is put along the winding of described mold insert outer ring.
Further, described mold insert is exhaust mold insert.
Further, the shape of cross section of described air discharge duct is semicircle, trapezoidal or rectangle.
Further, described exhaust apparatus is arranged between lower bolster and counterdie mold insert.
Technical scheme described in the utility model is with respect to prior art, and the beneficial effect of obtaining is:
(1) exhaust apparatus that the utility model adopts efficiently solves the tired gas problem of mould in process of production, and just can the greasy dirt between mold insert is clean clearly without shutting down form removal, has improved the quality of production efficiency and product.
(2) by the gap between mold insert, can effectively solve the tired gas problem in mold cavity, other of die cavity are discharged outside mould from gap, avoid note discontented or produce the phenomenons such as bubble, affect production efficiency.
(3) can, from exhaust passage by the greasy dirt mold insert gap or other Impurity removals, ensure normal exhaust in injection moulding process by exhaust apparatus, without removing mould, save time cost and cost of labor, while also ensure the quality of product.
Brief description of the drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms a part of the present utility model, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the top view of the utility model injection mold;
Fig. 2 is the profile of the utility model injection mold;
Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, clear, below in conjunction with drawings and Examples, the utility model is further elaborated.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.
As shown in Figure 1 and Figure 2, a kind of exhaust apparatus for injection mold, the embedding piece groove 210 that this mould comprises mold insert 100 and is opened in template 200 and embeds for mold insert 100; Described mold insert 100 is exhaust mold insert;
Between described embedding piece groove 210 and mold insert 100, be provided with an exhaust apparatus, the air discharge duct 110 that it comprises the exhaust passage 211 being arranged in embedding piece groove 210 and is opened in mold insert 100 bottoms; The corresponding air discharge duct 110 two ends 110A in described exhaust passage 211,110B position are offered downwards and are communicated with template 200 lateral walls; Wherein, between every adjacent two mold inserts 110, have a gap 400, described gap 400 is communicated with respectively air discharge duct 110 with exhaust passage 211.
More specifically, be also provided with a sealed groove 212 for sealing in described embedding piece groove 210, it is put along described mold insert 100 outer ring windings; The shape of cross section of described air discharge duct 110 is semicircle, trapezoidal or rectangle.
Specific embodiment, the present embodiment is arranged between lower bolster and counterdie mold insert as example taking described exhaust apparatus; First the lower bolster of mould is gone out to an embedding piece groove 210 embedding for mold insert 110 with Digit Control Machine Tool finish-milling, and with its bottom offer an annular or rectangle for seal place this sealed groove 212 of sealed groove 212(can prevent that air from spreading everywhere, cause mould in injection moulding process, produces be stranded gas); Then, offer an air discharge duct 110 in each mold insert 100 bottom surfaces with gap 400, (shape of cross section of air discharge duct 110 can be semicircle, trapezoidal or rectangle, and it is selected according to mold insert size and hardness), the gap 400 between adjacent two mold inserts 110 communicates with air discharge duct 110; Then, in the bottom surface of embedding piece groove 210 and the end positions of corresponding air discharge duct 110, be drilled with two exhaust passages 211, be drilled with after certain depth, be drilled with and be communicated with two exhaust passages 211 that previous brill is good from template lateral wall correspondence again, now, the gap 400 of each mold insert 110 is communicated with respectively air discharge duct 110 with two exhaust passages 211, finally mold insert 100 is embedded to embedding piece groove 210 and is fixed on template with screw.
In actual injection moulding process, the gas producing when injection moulding is expelled to air discharge duct 110 by the gap 400 between mold insert 100, and discharges mould from the exhaust passage 211 being communicated with air discharge duct 110; Producing after a period of time, inlaid piece of mould 110 is stopped up by greasy dirt, now can be blown into air from exhaust passage 211 by air gun or other high pressure tools; to get rid of the greasy dirt in mold insert gap 400; need not shut down and pull down mold cleaning, ensure the efficiency of producing, improve the quality of product simultaneously.
The utility model adopts exhaust apparatus effectively to solve the tired gas problem of mould in process of production, and just can the greasy dirt between mold insert is clean clearly without shutting down form removal, has improved the quality of production efficiency and product; By the gap between mold insert, can effectively solve the tired gas problem in mold cavity, other of die cavity are discharged outside mould from gap, avoid note discontented or produce the phenomenons such as bubble, affect production efficiency; Can, from exhaust passage by the greasy dirt mold insert gap or other Impurity removals, ensure normal exhaust in injection moulding process by exhaust apparatus, without removing mould, save time cost and cost of labor, while also ensure the quality of product.
