Abstract
In order to ensure that an ejector rod is separated from an injection molding product conveniently during the demoulding process of a deep-frame injection moulding product and no influence can be caused on the appearance of the product, the utility model provides an ejection mechanism for an injection mold. The ejection mechanism for the injection mold comprises an obliquely jacking rod and a slide block, wherein the section of the obliquely jacking rod is a parallelogrammic rod-shaped steel body, one angle of the parallelogram is 88 degrees, the slide block is provided with a groove capable of allowing the bottom of the obliquely jacking rod to slide inside the groove, and the thickness of the part of the obliquely jacking rod, which is positioned inside the groove, is smaller than those of other parts of the obliquely jacking rod.
Description
Technical field
The utility model relates to a kind of mould emptier of injection mold, specifically, relates generally to a kind of bottom that is applied in and is the oblique top mould emptier on the dark frame type injection-molded item of logical frame.
Background technology
In shown in Figure 1 the dark frame type injection-molded item of a bottom for logical frame, its demoulding scheme has two kinds usually: the one, inject lateral wall 12 places of moulding goods by a straight push rod, this scheme will stay the thimble seal at visible position, the outside of injection-molded item, influences product appearance; The 2nd, inject bottom surface frame 13 places of moulding goods by a straight push rod, this kind scheme can not have influence on the injection-molded item outward appearance, but straight push rod tightly sticked together all the time with injection-molded item inwall 11 in ejecting kind, because injection-molded item can not be released with adhesion that straight push rod produces in injection moulding process, injection-molded item is ejected the back and takes off comparison difficult from straight push rod.
The utility model content
In order to make dark frame type injection-molded item in knockout course; can realize the disengaging of push rod and injection-molded item with comparalive ease; do not influence simultaneously product appearance; the utility model proposes a kind of mould emptier of injection mold; comprise angle ejector rod and slide block; described angle ejector rod is that section is the shaft-like steel body of parallelogram, and described slide block has the groove that is slided in the angle ejector rod bottom within it, and described angle ejector rod is positioned at the segment thickness of groove less than other positions.Wherein, but described slide block is fixed in the vertical direction produces on the ejector retainner plate of motion.Described mould emptier has two angle ejector rods, and described angle ejector rod places respectively in two slide blocks, and described slide block all is fixed on the described ejector retainner plate.Further, one of them angle of described angle ejector rod section is 75 degree ~ 89 degree.
Introduce preferred embodiment below in conjunction with accompanying drawing, the technical scheme that the utility model proposes is described in detail.Should be noted that the purpose of accompanying drawing just is convenient to the explanation to the utility model specific embodiment, is not a kind of unnecessary narration or to the restriction of the utility model scope.
Description of drawings
Fig. 1 is a kind of dark frame type injection-molded item stereogram.
Fig. 2 is the stereogram of mould emptier of the present utility model when demoulding state.
Fig. 3 is the part figure of the utility model mould emptier groove part.
Fig. 4 is the part sectioned view of the utility model mould emptier push rod part.
The specific embodiment
As shown in Figures 2 and 3, after the injection moulding process of dark frame type injection-molded item 01 is finished, master mold is taken down, need injection-molded item 01 be broken away from from male model 02 by mould emptier.
The mould emptier of present embodiment comprises angle ejector rod 03 and slide block 05; described slide block 05 has the groove 51 that is slided in angle ejector rod bottom 31 within it; described angle ejector rod 03 is positioned at part 31 thickness of groove 51 less than other positions 32; after angle ejector rod 03 passes the groove 04 of male model 02, the bottom surface frame 13 of its top contact injection-molded item 01.
The number of described slide block and angle ejector rod is respectively two, produces on the ejector retainner plate of motion but two slide blocks all are fixed on an in the vertical direction.
As shown in Figure 4, described angle ejector rod 03 section is a parallelogram, one of them angle A of described parallelogram is 89 degree, in the knockout course of injection-molded item 01, ejector retainner plate drives slide block 05 and moves straight up, so that angle ejector rod 03 in the vertical direction is given 01 1 thrusts of injection-molded item, make it break away from male model 02, the motion of angle ejector rod 03 in groove 51 simultaneously makes it produce a sliding force with respect to injection-molded item 01 in the horizontal direction, make angle ejector rod 03 self and injection-molded item 01 produce a relative displacement, so that the most of adhesion between the two obtains discharging, thereby conveniently injection-molded item 01 is taken out from angle ejector rod 03.
By the angle ejector rod that a section is a parallelogram, make push rod angle of relative vertical direction inclination in the motion that promotes injection-molded item, can realize the disengaging of push rod and injection-molded item with comparalive ease, do not influence product appearance simultaneously again.The angle A of angle ejector rod section is preferably 75 degree ~ 89 degree.
The above only is a preferred implementation of the present utility model; but not to be the limitation of the utility model scope should be understood that for they; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, some improvements and modifications of having done also should be considered as within the protection domain of the present utility model.
Claims (4)
1. the mould emptier of an injection mold; comprise angle ejector rod and slide block, it is characterized in that described angle ejector rod is that section is the shaft-like steel body of parallelogram; described slide block has the groove that is slided in the angle ejector rod bottom within it, and described angle ejector rod is positioned at the segment thickness of groove less than other positions.
2. mould emptier according to claim 1 is characterized in that, produces on the ejector retainner plate of motion but described slide block is fixed on an in the vertical direction.
