Description
Technical field
The utility model relates to injection mold, particularly relates to the injection mold side wedge two mould emptier of interior back-off up and down.
Background technology
When after working of plastics injection mo(u)lding, if the sidewall of working of plastics is shaped with back-off and lower back-off, and upper and lower back-off is mutually corresponding, prior art does little by the degree of depth of upper and lower back-off, directly deviate from back-off by strong taking off again, therefore easily there is situations such as breaking in back-off, causes product rejection, scrappage is high, and owing to doing little by the back-off degree of depth, its fastening ability, when working of plastics and other parts assemble, it is unreliable to assemble, and affects result of use.For this reason, the lower oblique top 3 ' (as shown in Figure 5) that someone devises the upper oblique top 2 ' under the middle setting of side action sliders 1 ' of dynamic model is tilted to and tilts upward, upper oblique top coordinates with upper back-off 4 ', lower oblique top coordinates with lower back-off 5 ', on, lower oblique top other end is linking springs 6 ' and spacer pin 7 ' respectively, when side action sliders moves laterally, spring top is utilized to live in, lower oblique top, make, lower oblique top is not first outwards extracted out, but on, lower oblique top can deviate from back-off to the inside along the incline direction of oblique guide hole, again by side action sliders by upper, lower oblique top is extracted out laterally, but this structure is due on when matched moulds, lower oblique top can withstand on the wall of dynamic model, therefore the product of side-wall hole is only applicable to, and cannot be used for sidewall be shaped with simultaneously real face and, the product of lower back-off.
Summary of the invention
The purpose of this utility model is the shortcoming existed to overcome prior art; there is provided a kind of structure simple; the demoulding is smooth, and yield rate is high, and the sidewall being applicable to working of plastics is shaped with the injection mold side wedge two mould emptier of interior back-off up and down of real face and upper and lower back-off simultaneously.
In the utility model injection mold side wedge is upper and lower, the technical scheme of the two mould emptier of back-off is: comprise compound plate and lower compound plate, centring ring and gate bush are set in upper compound plate, under upper compound plate, cover half is set, between upper compound plate and cover half, Angle Pin is set, perforation is had in lower compound plate, lower compound plate arranges mould pin, lower compound plate between mould pin is arranged ejector retainner plate and lower ejector retainner plate, on, between lower ejector retainner plate, thimble is set, injector push rod contacts with below lower ejector retainner plate through perforation, mould pin arranges dynamic model, dynamic model arranges side action sliders, oblique guide hole is had in side action sliders, oblique guide hole matches with Angle Pin, the working of plastics of injection mo(u)lding is had between side action sliders and fixed half and moving half, working of plastics is shaped with sidewall, sidewall is shaped with back-off and lower back-off, on, lower back-off is corresponding, it is characterized in that: be shaped with side in described side action sliders and take out hole, upper pin-and-hole, lower pin-and-hole, upper spring groove and lower spring groove, take out in side in hole and skew back wedge is set, one of skew back wedge is connected with the piston rod of oil cylinder, locating hole is shaped with in skew back wedge, skew back wedge other end is shaped with oblique surface and lower oblique surface, upper oblique surface arranges inverted buckle slider, upper inverted buckle slider matches with the upper back-off of working of plastics, divide at lower oblique surface and put lower inverted buckle slider, lower inverted buckle slider matches with the lower back-off of working of plastics, described is upper, in lower pin-and-hole, alignment pin is set, alignment pin is through upper inverted buckle slider, lower inverted buckle slider and skew back wedge, and with locating hole left and right sides inwall aligned contact, in described upper spring groove, spring is set, upper spring contacts with upper inverted buckle slider, in lower spring groove, lower spring is set, lower spring contacts with lower inverted buckle slider.
The utility model discloses a kind of injection mold side wedge two mould emptier of interior back-off up and down, when after working of plastics injection mo(u)lding, first skew back wedge is driven to move laterally by the piston rod of oil cylinder, other end due to skew back wedge is shaped with upper oblique surface and lower oblique surface, and upper oblique surface contacts with upper inverted buckle slider, lower oblique surface contacts with lower inverted buckle slider, therefore when skew back wedge moves laterally, upper spring promotes inverted buckle slider downwards, inverted buckle slider is made to deviate from the upper back-off of working of plastics gradually downwards along upper oblique surface, lower spring upwardly descends inverted buckle slider, make lower inverted buckle slider along the lower back-off of lower oblique surface prolapse upwards working of plastics gradually, when skew back wedge moves to certain position to side, on the right side of locating hole in skew back wedge, inwall contacts with alignment pin, alignment pin offside wedge plays positioning action, prevent its continuation from moving laterally, this is compound plate band dynamic model pin at present, dynamic model, upper ejector retainner plate, lower ejector retainner plate, side action sliders and working of plastics move backward, mould die sinking, while side action sliders backward movement, the oblique guide hole of side action sliders coordinates with Angle Pin, side action sliders moves laterally along the incline direction of Angle Pin, side action sliders drives skew back wedge and upper, lower inverted buckle slider moves laterally, make, lower inverted buckle slider departs from working of plastics, finally driven by injector push rod, lower ejector retainner plate, on, lower ejector retainner plate drives thimble by working of plastics ejection device, when mould matched moulds, lower compound plate band dynamic model pin, dynamic model, upper ejector retainner plate, lower ejector retainner plate, side action sliders and working of plastics move forward, the inside homing of side action sliders is driven by Angle Pin, and the piston rod of oil cylinder inwardly promotes skew back wedge simultaneously, the upper oblique surface of skew back wedge promotes upper inverted buckle slider and overcomes upper spring force upwards homing, lower oblique surface promotes lower inverted buckle slider and overcomes the downward homing of lower spring power, when the locating hole inner left wall of skew back wedge contacts with alignment pin, alignment pin offside wedge enter and on, lower inverted buckle slider location, prevent skew back wedge and upper, lower inverted buckle slider inwardly pushes up on dynamic model, skew back wedge and upper, leave certain interval between inverted buckle slider and dynamic model down, the working of plastics sidewall of injection mo(u)lding is made to be shaped with real face, and be shaped with on real face, lower back-off.
The utility model injection mold side wedge is the two mould emptier of interior back-off up and down; described upper spring groove communicates with upper pin-and-hole; lower spring groove communicates with lower pin-and-hole, and alignment pin is simultaneously through upper pin-and-hole, upper spring groove, upper inverted buckle slider, locating hole, lower inverted buckle slider, lower spring groove and lower pin-and-hole.Upper pin-and-hole, upper spring groove, lower spring groove and lower pin-and-hole are on the same axis, alignment pin moving left and right of offside wedge can play positioning action, guide effect can be played to upper and lower spring and upper and lower inverted buckle slider again, make the mobile guide that is flexible and upper and lower inverted buckle slider of upper and lower spring more accurate.
