Abstract
The utility model discloses an exhaust slipper on a mould for injection moulding, which belongs to the technical field of the mould for injection moulding. The exhaust slipper is provided with lug bosses used for forming holes for eliminating heat during injection moulding. The tops of the lug bosses are provided with patching surfaces. The exhaust slipper is provided with a plurality of exhaust passages. The inlets of the exhaust passages are arranged on the patching surfaces. The outlets of the exhaust passages are arranged on the external surface of the exhaust slipper. The exhaust passages extend inside the exhaust slipper. The gases generated from the injection moulding process can penetrate into the inlets of the exhaust passages from the patching surfaces, and then pass through the exhaust passages before the gases are exhausted from the outlets of the exhaust passages, thus preventing burr from occurring to the wall of the holes for eliminating heat.
Description
Technical field
The utility model relates to a kind of exhaust slide block that is used on the injection forming mold, belongs to the technical field of the mould of injection mo(u)lding.
Background technology
The range of work of injection molding process is very wide, and existing electronic product shell all adopts injection molding process to make usually.Generally all offer louvre on the electronic product shell to be used for the heat radiation of product internal electron structure, this louvre need be offered groove width at the hole wall place corresponding to louvre and be the air discharge duct (referring to accompanying drawing 1, accompanying drawing 2) below the 0.1mm on the slide block of mould when injection mo(u)lding.Air discharge duct can make the high-temperature gas that produces in the die discharge, and can prevent that on the one hand high-temperature gas from causing turning white of thin hole wall or burn, and can prevent that on the other hand gas from impacting the quality of shaped article.Be easy to generate burr when yet air discharge duct is in injection moulding, need repair, waste man-hour shaped article.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of exhaust slide block that is used for injection forming mold, and this exhaust slide block can be discharged the high-temperature gas in the die, can prevent to produce on the shaped article simultaneously burr.
The technical scheme that the utility model adopted is: the exhaust slide block on a kind of injection forming mold, has the boss that is used for forming louvre in injection mo(u)lding, the top of described boss has breaking face, offer a plurality of exhaust passages on the described exhaust slide block, the exhaust passage inlet of described exhaust passage is opened on the described breaking face, the exhaust passage outlet of described exhaust passage is opened on the outer surface of described exhaust slide block, and described exhaust passage is in the inner extension of described exhaust slide block.The gas that produces in the injection molding process process can be penetrated into porch, described exhaust passage from breaking face thus, then by the exhaust passage, discharges in the exit, exhaust passage, can avoid producing burr on the hole wall of louvre.
The cross sectional shape of described exhaust passage is circular, and the diameter in the cross section of described exhaust passage is 2 millimeters.
The bearing of trend of the part of the close described breaking face of described exhaust passage and described breaking face are perpendicular.The bearing of trend of the part of the close described exhaust passage outlet of described exhaust passage and outlet plane, place, described exhaust passage are perpendicular.Outlet plane, place, described exhaust passage and described breaking face are perpendicular.
Advantage of the present utility model is: can discharge the high-temperature gas in the die on the one hand smoothly, can prevent to produce on the shaped article burr on the other hand.

The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail:
The cross sectional shape of described exhaust passage 4 is circular, and the diameter in the cross section of described exhaust passage 4 is 2 millimeters.Repeatedly practise through the engineer, the exhaust passage 4 of this size can realize effective discharging of gas and be easy to processing realizing.
The bearing of trend and the described breaking face 31 of the part of the close described breaking face 31 of described exhaust passage 4 are perpendicular.It is perpendicular that the bearing of trend of the part of the close described exhaust passage outlet 42 of described exhaust passage 4 and described exhaust passage export plane, 42 place.Preferred, described exhaust passage exports plane, 42 place and described breaking face 31 is perpendicular, thus when offering exhaust passage 4, drill bit 41 places that at first enter the mouth in predetermined exhaust passage on breaking face 31 pierce a blind hole with desired depth, on the outer surface of exhaust slide block 1, export 42 places again and pierce the blind hole that another has desired depth in predetermined exhaust passage, guarantee that two described blind holes are connected, promptly finish the processing of described exhaust passage 4, processing is simple.
