Abstract
The present invention provides a kind of vertical ranking bent pipe injection dies, devise a cavity per mould spot pouring mouth injection mold, and demoulding exceptionally wall demoulding and the inner wall of product demould two kinds of situations and carry out；The demoulding of outer wall is demoulded using 3 conventional demoulding mechanisms；It includes 1 oil cylinder side core pulling clamp mechanism, 1 flexible oblique core_pulling demoulding clamp mechanism of sliding block of special hydraulic oil cylinder driving band and 1 deformation type mandril clamp mechanism that the demoulding of inner wall, which uses a kind of special combined type elbow internal wall demoulding mechanism, structure composition,；The especially design of the oblique core_pulling demoulding clamp mechanism of the flexible sliding block of hydraulic oil cylinder driving band; piecemeal processing is carried out to intracanalicular type core; implement linear core pulling; the bend loss for avoiding elbow internal wall demoulds the problems such as caused mechanism design is complicated and demoulding mechanism acts complexity using traditional rotary core pulling mode, significantly reduces die manufacturing cost；Mechanism structure design is simple, reliable in action, and mould structure is reasonable.
Description
Technical field
The present invention relates to injection mold mechanism design field, specially a kind of vertical ranking bent pipe injection die.
Background technology
As shown in Figure 1, being pump line union elbow product, body feature is made of three parts, and both ends are straight tube, and centre is
The biggest problem of bend pipe, product injection molding is that the core pulling at bend pipe end on product is smeared, the specific feature distribution situation of product
For：First straight tube is the straight barrel end of 136mm outer diameters, and the outer diameter of the second straight tube is the straight barrel end of 121mm, both ends straight tube
Center angle is 120 °；The end face of both ends straight tube is respectively designed with respective end surface features, and the end faces 136mm are pipe feature, F6
Outer edge fillet R2mm at meaning；F7It is the 140mmx127mm rectangular slab band straight hole features of the end faces 121mm at meaning, 4
A diameter of 16mm of straight hole；The straight tube end at both ends is bound up by intermediate bend pipe end, and bend pipe sweeping fan angle is
60 °, wherein F4The bend loss radius of central line in signified region is r=110.5mm；F outside tube wall3There is concave to carve characters at position；F5
Radius is the ball impression of R4 at meaning；F1、F2Cup depth at meaning is 10mm；（In Fig. 1, F1~F7Feature locations）；Demoulding
Analysis combines Fig. 1, as shown in Fig. 2, the parting of product designs the demoulding of the difficult genius loci of demoulding of palpus combination product to carry out
The problem of layout arranges, and the demoulding of product design faces two aspects, one is in pipeline core members extraction demoulding, in addition one
The demoulding of convex and concave feature outside a tube wall, demoulding complexity and the layout of product in a mold of pipeline external feature put phase
It closes, different layouts is put, and for specific location feature, the case where demoulding is different；It is directed to for the outer feature of pipe, no
Same putting can cause F1、F2、F3、F5、F6、F7The difference of the stripping direction of feature in region, it is special that some possibility also need to increase
Core-pulling mechanism, thus layout of the product in mold puts the difficulty or ease journey for influencing that mechanism designs in the design of this product mould structure
Degree and mold manufacturing cost（In Fig. 2, F1~F7Feature locations；T1~T8Stripping direction；L1、L2Core line of demarcation；
O1Bent pipe fan-shaped center；M- core pullings blind area）.
As shown in figure 3, there are two types of layout type for the layout of this product in a mold, one is layout side as shown in Figure 3a
Formula, the second is layout type as shown in Figure 3b；If be laid out using shown in Fig. 3 a, the demoulding situation of outer wall feature is：F1、
F2Provincial characteristics is demoulded regardless of mechanism is increased, F3、F5、F6、F7Side core-drawing mechanism must be designed to demould, in the bend pipe of the regions F4
The bad design of the drawing mechanism of the core in the regions M on wall, and T6、T8The setting of the core-pulling mechanism in direction will increase mold mould bases
Length and width dimensions sharply increase the cost of mold mould bases；On the contrary, if pressing vertical layout shown in Fig. 3 b, F4M on the elbow internal wall of region
The relatively good design of drawing mechanism of the core in region, can directly individually designed jacking block ejection, the size of mold mould bases is most
It is small, but its drawback is F1、F2、F3、F6Provincial characteristics must design side core-drawing mechanism to realize demoulding；For F1、F2、F3、F6Region
Feature after further feature dimension analysis, it is known that：F1、F2Side sliding block can be used and carry out core_pulling demoulding, F3 can be used
Preceding mould elder generation core-pulling slide block progress core_pulling demoulding, and F6Then directly demoulded using side core pulling mode, thus, through it is preliminary at
After this accounting, the manufacturing cost of these mechanisms is comparatively cheap, so the vertical body formula placement scheme of bend pipe is more feasible（Fig. 3
In, a- bend pipe horizontal lying-types layout；B- bend pipes found body formula layout；C- product partings design；T1~T7Stripping direction；X, Y, Z- mold

Outer rack guide pad is oriented to, and is coupled by the core bar of lower oil cylinder and is driven it to drive outer sliding tooth wheel to rotate；In order to ensure
When mold closing is molded, the second straight tube end pipe end cylinder core is under injection pressure not along T8Pine moves back in direction, and skewed slot, circle are oriented to by part
The retaining mechanism that column type core latch segment, latch segment inserted link are constituted locks the second straight tube end pipe end cylinder core, has
Body running situation is slidably matched with cylinder core latch segment by T-slot for latch segment inserted link to be coupled, and latch segment inserted link is in Pk3Point
Cylinder core latch segment is locked when being closed in type face, and is locked by guiding skewed slot, conversely, Pk3It is driven when opening
Outside core pulling unlock；
Intracanalicular type core is through PL in the bending-type mandril ejection device mechanism of the blind areas M5、PL6It is partitioned into the bending-type molding of the blind areas M
The lower end of the molded part is made the curved blind areas M in the part of mandril form and is molded mandril by part, and lower end passes through screw fastening means
It is fastened on thimble push plate, waits for that the second straight tube end pipe end cylinder core drags left telescopic block and right telescopic block from inner wall of the pipe
It is synchronous to eject product from core mold insert with ejector sleeve after abjection.
In the present invention：Outer mold wall demoulding mechanism solve the technical issues of be：Vertical layout and the product outer wall that generates is special
Sign demoulding requires, and the advantageous effect reached is：Realize the complete demoulding of product outer wall.
In the present invention：Inside pipe wall demoulding mechanism component solve the technical issues of be：The linear core pulling mode of elbow internal wall, reaches
To advantageous effect be：Avoiding the horizontal rotary demoulding mechanism of layout brings mold mould bases larger, cost to steeply rise,
