Abstract

The utility model discloses an injection mold exhaust system, including cope match -plate pattern and lower bolster, be provided with die cavity and guide bar on the cope match -plate pattern, be provided with down die cavity and guiding hole on the lower bolster, go up the die cavity and form the die cavity that matches with the work piece with lower die cavity, its characteristics are: along being provided with a plurality of air discharge duct structures around the die cavity down, the air discharge duct structure comprises " M " type gas tank and the gas tank that gathers on the die joint of lower bolster, and the gas tank that gathers is connected in the centre of " M " type gas tank, still is provided with the peening groove on the die joint of lower bolster. The utility model discloses a by " M " type gas tank and the air discharge duct structure that the gas tank constitutes that gathers, conveniently surperficial gas trace, gas line, the seam of injection moulding product has been solved with gas outgoing, surface profile phenomenon such as unclear, the setting in peening groove, the interior air of mould cavity and runner of thoroughly discharging effectively avoids injection moulding product the flaw to appear.

Description

A kind of injection mold gas extraction system
Technical field
This utility model belongs to mould production technical field, especially relates to a kind of injection mold gas extraction system.
Background technology
Injection mold belongs to swaging die, has large quantity of air in die cavity, when fused raw material rapidly enters die cavity, these are empty Gas is discharged in time, meanwhile, when fused raw material molds after forming and hardening in die cavity, can produce true between product and cavity wall Sky, air must timely enter.Due to this defect of injection itself, injecting products are made to there are problems, such as product surface Form gas trace, gas stricture of vagina, seam, surface profile is unclear etc., the problem that the exhausting problem of mould has become as urgently and solves.
Content of the invention
The purpose of this utility model is the deficiency existing for above-mentioned prior art, provides a kind of injection mould of smooth in exhaust Tool gas extraction system.
To achieve these goals, this utility model be employed technical scheme comprise that:A kind of injection mold gas extraction system, bag Include cope match-plate pattern and lower template, described cope match-plate pattern be provided with upper impression and guide post, described lower template is provided with lower impressions and The die cavity that pilot hole, upper impression and lower impressions formation are matched with workpiece, the die joint of described lower template sets along around lower impressions It is equipped with multiple vent groove configuration, described vent groove configuration by " M " type air drain and collects air drain and constitutes, and the described air drain that collects is connected to The centre of " M " type air drain, the die joint of described lower template is additionally provided with shot-peening groove.
Described shot-peening groove is to carry out shot-peening by silicon carbide abrasive to die joint to be formed.
After said structure, this utility model is compared to the prior art advantageously:This utility model adopts By " M " type air drain with collect the vent groove configuration that air drain form, facilitate and gas is discharged, solve the gas of injection product surface Trace, gas stricture of vagina, seam, the phenomenon such as surface profile is unclear;The setting of shot-peening groove, can thoroughly discharge the sky in mold cavity and runner Gas, is prevented effectively from injecting products and flaw.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Described below is only preferred embodiment of the present utility model, does not therefore limit protection model of the present utility model Enclose, with reference to the accompanying drawings and examples this utility model is further illustrated.
Embodiment, as shown in Figure 1:A kind of injection mold gas extraction system, including cope match-plate pattern (accompanying drawing is not drawn into) and lower template 1, described cope match-plate pattern is provided with upper impression and guide post, described lower template 1 is provided with lower impressions 2 and pilot hole 3, upper impression Form the die cavity matching with workpiece with lower impressions 2, the above is prior art construction, other prior art construction are no longer superfluous State, the feature of the present embodiment is:It is provided with multiple vent groove configuration 4 along around lower impressions 2 on the die joint 5 of described lower template 1, Described vent groove configuration 4 by " M " type air drain 41 and collects air drain 42 and constitutes, and the described air drain 42 that collects is connected to " M " type air drain 41 Centre, the die joint 5 of described lower template 1 is additionally provided with shot-peening groove (accompanying drawing is not drawn into), described shot-peening groove is by carborundum Abrasive material carries out shot-peening to die joint 5 and is formed.
When sizing material enters die cavity from gum-injecting port, the gas in die cavity is discharged from vent groove configuration 4 and shot-peening groove.Due to Vent groove configuration 4 is by " M " type air drain 41 and to collect air drain 42 and constitute, and its version increased the length of air discharge duct, can prevent Only sizing material flows out from vent groove configuration 4, and the warp architecture of " M " type air drain 41 can reduce the flowing velocity of sizing material, therefore can subtract Few sizing material flows in vent groove configuration 4.
