Rubber support Parting Surface of Injection Mold designs
The selection of die joint is the problem of a more complicated, because it is subject to the impact of the various factors such as the shape of goods, shaping position, pushing method, die cavity exhaust, Making mold and operation.This product design is cuboid, product is produced sidewards, it may cause the cross-sectional area of mould to increase, but the working region of injector sulfuration flat board can meet the demands completely, therefore the die joint of mould is selected on product center cross section, as shown in Figure 2, ejects resistance to reduce product, the flow distance that sizing material enters in die cavity is shorter, is beneficial to shortening cure time.
Rubber support injection mould Position Design
1. rubber support skeleton Position Design in a mold described in
Described rubber support product skeleton comprises slab 9, thin plate 10 and the intermediate plate between slab 9 and thin plate 10 11.Slab 9 wherein, thin plate 10 profile are rectangle, and intermediate plate 11 is oval.Slab 9 height dimension is
location, this direction relies on upper model cavity height
with counterdie die cavity height
jointly complete.Thin plate 10 height dimension is
location, this direction relies on upper model cavity height
with counterdie die cavity height
jointly complete.Slab 9, thin plate 10 are rely on its endoporus φ in the location of length direction
with left core 3, right core 4 φ
come.The location of slab 9, thin plate 10 left and right directions relies on slab top shoe 5, slab sliding block 6, thin plate top shoe 7 and thin plate sliding block 8 to ensure.6 ° of inclined-planes in slab top shoe 5 and patrix 1, counterdie 2 respective ramp bedding-in, contact rate is greater than 80%, ensure that slab 9 under matched moulds state, thin plate 10 accurately locates, be convenient to again open part, as shown in Figure 2 and Figure 5.
Intermediate plate 11 4 limit of described rubber support skeleton is all surrounded by the thick rubber layer of 2mm 38, forms inner suspension formula structure.The die joint of mould is again in the centre of product, and this just just in time makes intermediate plate 11 insert in elongated slot 41, and intermediate plate is accurately positioned in direction, all around simultaneously, and the location of above-below direction is according to four locating slots 40 at the upper and lower sides of intermediate plate 11.Along with the carrying out of mould assembling action, slab 9, intermediate plate 11 and thin plate 10 are all accurately fixed, as shown in Figure 6 and Figure 7.
2. rubber support injection mould self position components and and equipment between Position Design
Described rubber support injection mould is connected with hanger on equipment by the bolt of the elliptical aperture M12 on patrix 1.Counterdie 2 is matched by the specialized nut in the bolt of the rectangular fluting M12 of 8 the wide 14mm T-slot 37 corresponding to equipment, as shown in Figure 1.
Location between described rubber support injection mould its patrix 1 and counterdie 2, is come by four guiders (alignment pin 15 and set pin sleeve 16), for the ease of matched moulds, alignment pin 15 is designed to taper to play the guiding role.4-φ 26 step alignment pin 15 is fixed on patrix 1 by the quality of fit of H8/s8, the set pin sleeve 16 of 4-φ 44 is fixed on counterdie 2 by the quality of fit of H8/s8, and select alignment pin 15 and coordinating between dowel hole H8/f7, to ensure the closing precision of patrix 1 and counterdie 2.In order to make alignment pin 15 have good steering capability, do globulate in the pilot section of alignment pin 15, the size of targeting part should larger than depth of cavity go out about 20mm, and localization part is 10mm, to ensure the positioning requirements of patrix 1 and counterdie 2, as shown in Figure 1.
The left core 3 of described rubber support injection mould, right core rod 4 and patrix 1, location between counterdie 2, it is the core 3 that keeps left, 10 ° of inclined-planes of right core 4 one end and patrix 1, counterdie 2 respective ramp phase bedding-in realizes, in patrix 1,10 ° of inclined-planes are the right and left, so just left core 3 and right core 4 are completely accurately fixed in the position of left and right directions, in counterdie 2, only there is (the i.e. right side of left core 3 on 10 ° of inclined-planes leaning on into die cavity place, the left side of right core 4), so just cause left core 3, right core 4 is engaged in left and right directions with counterdie 2 and there is activity phenomenon, so turn increase movable left core alignment pin 14 and right core alignment pin 14, it and counterdie fit clearance are 0.5mm, as shown in Figure 2.
Described rubber support injection mould slab top shoe 5 and the location between thin plate top shoe 7 and patrix 1 are by slab top shoe 5, 6 ° of inclined-planes on thin plate top shoe 7, slab sliding block 6 and the location between thin plate sliding block 8 and counterdie 2 are by 6 ° of inclined-planes on slab sliding block 6 and thin plate sliding block 8, slab top shoe 5 after matched moulds, thin plate top shoe 7, inclined-plane on slab sliding block 6 and thin plate sliding block 8 and patrix 1 and counterdie 2 respective ramp bedding-in, ensure slab top shoe 5, thin plate top shoe 7, the positional precision of slab sliding block 6 and thin plate sliding block 8, as shown in Figure 2.

The design of rubber support injection die drawing hopper
Described rubber support injection die drawing hopper 43 is that the hemispherical being φ 8mm by place in the φ 20mm hemispherical at main running channel turning and gum-injecting port realizes, glue in its guarantee running channel is when mould die sinking, be left on plane on counterdie 2, draw hopper as what show main running channel turning in Fig. 3, what Fig. 8 showed note cast gate place draws hopper.
Rubber support injection mould overflow glue groove design
In process of production, redundant rubber stock flows into from die joint the glue groove 25 that overflows and forms glue limit rubber, and the domestic removal to glue limit is a difficult problem.Described rubber support injection mould forms large glue limit and the structure retained by the design of the glue groove that overflows greatly.
Described rubber support injection mould overflow glue groove 25 be by die joint both sides design width identical with intermediate plate thickness be
the dark groove of 6 thick 3 realizes, it communicates with die cavity formation del, because inverted-triangular groove bottom is connected with die cavity, can the inflow of the unnecessary glue of expedite guarantee and type intracavity gas, on product, just form two prismatics after such sulfuration be merged into glue more than handstand quadrangular form, as shown in Figure 10.
Rubber support injection mould venthole designs
Described rubber support injection mould venthole is that pore I 26 is designed in the centre of sizing material between the adjacent intermediate plate 11 of upper model cavity, dark 10mm is (because there being the existence of running channel, not easily get through hole), like this sizing material to lower and on fill die cavity time, the air be extruded just is discharged in venthole I 26; The centre symmetric design venthole II 27 of sizing material between the adjacent intermediate plate 11 of counterdie die cavity, described venthole II 27 is through hole, and as shown in Figure 5, such sizing material is toward the gas not also being able to do in time during hemostasis upwards to arrange, just be squeezed in the venthole II 27 of counterdie, be discharged to outside mold cavity.
Drop-down design in auxiliary system
