The utility model is capable of achieving the purpose of automatically cutting the feeding of sizing materials through the drawbar which externally hangs on the lateral surface of the mold, thereby reducing the cost of the mold with a drawbar of the utility model, increasing the inner space, and greatly reducing the processing difficulty.
Description
Affiliated technical field
The utility model relates to a kind of injection forming mold, relates in particular to a kind of lower link bar of injection forming mold.
Background technology
In the design of existing mold, especially in the design of three template dies, need the design lower link bar to limit the stroke between the upper mounted plate and stripper plate and stripper plate and caster in the die sinking process, in the die sinking process, reaching the purpose that sizing material into separates with shaped article automatically, thereby need manually cut-out advance sizing material.Should comprise the contour screw and the body of rod by existing lower link bar, the contour screw and the body of rod all are installed in four corners of mould inside, contour screw runs through the bottom plate of mould and is connected with the body of rod, the body of rod comprises bar head and shaft, the bar head is fastened in stripper plate inside, and shaft inserts in the male model plate after passing stripper plate and caster.
In this mould design, need form the space of lower link bar at the cavity volume that four jiaos of male model plates process corresponding lower link bar, and lower link bar itself occupied the inner space of stripper plate and caster, therefore increased Mould design difficulty, difficulty of processing and manufacturing cost.
Summary of the invention
The utility model purpose at above-mentioned the deficiencies in the prior art a kind of low cost is provided, the little mould of easily processing, take up room with pull bar.
For reaching above-mentioned purpose, the mould that the utlity model has pull bar comprises upper mounted plate, place the upper mounted plate below the male model plate, place male model plate below caster, place the caster below stripper plate, place the bottom plate of stripper plate below.Wherein, on the lateral surface of bottom plate, stripper plate and caster, be equiped with at least one pull bar, this pull bar has contour screw, stop block and the body of rod, contour screw passes bottom plate and is fixed on the body of rod, the part of the body of rod is fixed on the lateral surface of stripper plate, a part flexibly connects with stop block, and stop block is fixed on the lateral surface of caster.
From the above mentioned, the utility model only can be realized stroke between qualification bottom plate and stripper plate, stripper plate and the caster by an outer pull bar that hangs on the mould lateral surface in the die sinking process, thereby realize cutting off the purpose of material automatically, therefore, need not to process the male model plate for this reason, significantly reduce its difficulty of processing, increased its inner space simultaneously and be convenient to Mould design.

The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
See also Fig. 1 and Fig. 2, the mould that the utlity model has pull bar comprises bottom plate 11, places the stripper plate 12 of bottom plate 11 tops, places the caster 13 of stripper plate 12 tops, the male model plate 14 that places caster 13 tops, the upper mounted plate 15 that places male model plate 14 tops and pull bar 20.Pull bar 20 is fixed on the lateral surface of stripper plate 12, and the two ends active card of pull bar 20 is connected on the lateral surface of bottom plate 11 and caster 13.
The outside horizontal-extending in relative both sides of bottom plate 11 forms outstanding edge 111, the installation site of the corresponding pull bar 20 in outstanding edge 111 two ends offers the manhole 112 that runs through this outstanding edge 111, this through hole 112 has the first half and the Lower Half that diameter does not wait, to form the step (not shown).Offer groove 121 on the lateral surface of stripper plate 12,, offer two the 3rd screw holes 122 on the stripper plate 12 in the both sides of groove 121.Then offer shallow slot 132 on the lateral surface of caster 13.In shallow slot 132, offer two the 4th screw holes 131 on the caster 13.
See also Fig. 3, Fig. 4 and Fig. 5, this pull bar 20 has the body of rod 21, stop block 22 and contour screw 23.Contour screw 23 is formed by all being cap nut 231, screw body 232 and the screw terminal 233 that cylindrical shape and diameter successively decrease successively from top to bottom successively.Wherein, cap nut 231 diameters less than the diameter of through hole 112 Lower Halves of bottom plate 11 greater than the diameter of through hole 112 first halves, thereby cap nut 231 can be housed in the Lower Half of through hole 112 and can fasten step in the through hole 112; Then less than through hole 112 first half diameters, this screw body 232 is fixed on the body of rod 21 after passing this through hole 112 screw body 232 diameters, thereby contour screw 23 can be fastened in the through hole 112 of outstanding edge 111 of bottom plate 11.
The body of rod 21 has the bar head 212 that is rectangular-shaped, and bar head 212 end faces offer a bar head screw hole 211, is used for fixing the screw terminal 233 of contour screw 23, so that the body of rod 21 and contour screw 23 are fixed together.Bar head 212 outwards stretches out a projection 215 (as shown in Figure 5) towards the middle part, a side of stripper plate, in the groove 121 that this projection 215 embeds on stripper plate 12 lateral surfaces, both sides at projection 215, offering two the 3rd screw holes 122 that run through first screw hole, 216, the first screw holes, the 216 public stripper plates 12 of these bar head 212 left and right sides on the bar head 212 cooperates by corresponding screw 30 bar head 212 is fixed on the lateral surface of stripper plate 12.Middle part, bar head 212 bottom surfaces upwards vertically extends one and is rectangular-shaped shaft 213, "T"-shaped holding section 214 of shaft 213 terminal formation, holding section 214 is used to fasten stop block 22 to limit the scope of activities of the body of rod 21, this holding section 214 also can be other shape, for example semicircle sphere etc.
Please refer to shown in Figure 6, certainly, pull bar 20 is installed on four corners, the die main body outside and only is preferred implementation, and pull bar 20 also can be installed on any other position in the die main body outside, and pull bar 20 quantity that are installed on outside the die main body also can be decided according to actual needs.Correspondingly, the through hole 112 on the bottom plate 11 outstanding edge 111 also is opened in corresponding position according to the installation site and the quantity of pull bar 20.
In the die sinking process, at first, the male model plate 14 and the caster 13 that tightly lock together move upward together by shutter (figure does not show) in upper mounted plate 15 drives, caster 13 is separated with stripper plate 12, thereby cut off sizing material (figure does not show), then along with caster 13 continue move upward, the stop block 22 that is fixed on caster 13 sides is also shifted to holding section 214 and is finally fastened on holding section 214 along shaft 213, thereby drive stripper plate 12 moves upward and separates with bottom plate 11, after separating a segment distance, the cap nut 231 of the contour screw 23 that is connected with stripper plate 12 fastens the step in the through hole 112 of giving prominence to edge 111, thereby make caster 13 and stripper plate 12 stop motions, but male model plate 14 still continues along with the die sinking system moves upward, final shutter can't bear the pulling force of male model plate 14 and separate, separate between male model plate 14 and the caster 13, the thimble of mould (figure does not show) ejects the moulding product simultaneously, and finishes die sinking.
From the above mentioned, the bar head 212 of the utility model pull bar 20 is fixed on the lateral surface of stripper plate 12, being connected on the bottom plate 11 of contour screw 23 activities, stop block 22 is fixed on the lateral surface of caster 13, and holding section 214 activities fasten stop block 22, thereby reach the effect that limits stroke between bottom plate 11 and stripper plate 12, stripper plate 12 and the caster 13, and needing in the prior art to have avoided processing that the male model plate is carried out, increase the inner space of mould, thereby helped simplifying Mould design.
