Description
Technical field
The present invention relates to a kind of improvement of laminated type vibration isolating suspension mould.
Background technology
Shock isolating pedestal adopts the mold pressing form to process mostly at present.Process is: adopt one deck rubber, one deck steel plate stacked, drop in the mould; Then, in die cavity, inject quantitative sizing material; At last from top to bottom the pressurization, sulfidization molding (side wraps glue-line).This cooked mode follows so far, and the main amount that drops into sizing material, the pressure of pressurization, the performance of sizing material self of relying on determines.From product overall dimensional accuracy control aspect, the diameter of product can be guaranteed uniformity.But in the actual production, we find, the situation that deviation appears in finished product thickness often occurs again.Occasion for needs use shock isolating pedestals such as skyscraper, bridges even if small like this error appears at the bottom surface, also can cause the very big deviation in top, positive so-called " least bit of difference, a thousand li of mistake ".We analyze reason and find to cause the main cause of this situation to be: because the trueness error of steel plate flatness, can make that deviation appears in the integral thickness after stacked; When effectively controlling the total amount of rubber, can cause the height of final finished inconsistent.In the reality, the steel plate flatness is too high not to be best processing form for the shock isolating pedestal product, sometimes, need have some burrs on edges, whole warpage etc., to increase the shear strength of product integral level direction.
Summary of the invention
The present invention is directed to above problem, provide a kind of and can adapt to the requirement of steel plate low degree degree, can produce the mould of the shock isolating pedestal of high accuracy finished product simultaneously.
Technical scheme of the present invention is: comprise the counterdie of dish type, the middle mould of tubular, the patrix of dish type and the core rod of cylindricality, also comprise pressing plate, described pressing plate bottom surface is provided with an annular bead;
Mould inner core surface was provided with a circle groove during described patrix end face was corresponding described, be close to described groove outward flange position in described groove floor and be evenly equipped with some strips and annotate and press the hole, make described notes press the hole be communicated with described in the inner core of mould and outer ledge that described notes are pressed the hole corresponding described in the inner core surface of mould;
Described annular bead and described groove flexibly connect.
Described patrix bottom surface outer edge is offered a circle step circle, and the bottom surface of described step circle be used for the fitting end face of described mould makes described patrix bottom surface equal the height of described shock isolating pedestal apart from counterdie end face distance.
Press between the hole at the described adjacent notes of the bottom surface of the groove of described patrix and also to be provided with small through hole.
The forming cavity of mould of the present invention (constituting) constant dimension by counterdie end face, middle mould inner core face, core rod outer surface and patrix bottom surface, after inserting shock isolating pedestal blank (promptly not having the side surface overcoat) in the mould of the present invention, between blank side and middle mould inner core face, can leave side surface overcoat space, and the space between blank end face upper sealing plate and the superiors' rubber (height gap that this space is promptly reserved).After injecting sizing material in the strip notes pressure hole, sizing material is filled aforementioned two spaces, the final curing typing.Like this, can guarantee the finished product height strict conformance made.In addition, when preventing the lacunula injecting glue, the top may have high-voltage air-gap, and for this reason, the present invention is provided with small through hole with relatively exhaust on patrix.The present invention can effectively control the dimensional accuracy of finished product, makes the product size of batch process constant.The basic error of " primitiveness " when thoroughly avoiding the user to use.

The specific embodiment
The present invention comprises the counterdie 5 of dish type, the middle mould 2 of tubular, the patrix 3 of dish type and the core rod 4 of cylindricality shown in Fig. 1-4, also comprise pressing plate 1, and described pressing plate 1 bottom surface is provided with an annular bead 11;
Mould 2 inner core surfaces were provided with a circle groove 32 during described patrix 3 end faces were corresponding described, be close to described groove 32 outward flange positions in described groove 32 bottom surfaces and be evenly equipped with some strips and annotate and press hole 320, make described notes press hole 320 be communicated with described in the inner core of mould 2 and outer ledge that described notes are pressed hole 320 corresponding described in the inner core surface of mould 2;
Described annular bead 11 flexibly connects with described groove 32.Can realize axial mutual motion.Can clamp-on sizing material like this.
Described patrix bottom surface 31 outer edge are offered a circle step circle, and the bottom surface 30 of described step circle be used for the fitting end face 21 of described mould makes described patrix bottom surface 31 equal the height H of finished product shock isolating pedestal apart from counterdie 5 end faces distance.
Press between the hole 320 at the described adjacent notes of the bottom surface of the groove 32 of described patrix and also to be provided with small through hole 321.Wherein small through hole 321 has numerous embodiments, among Fig. 4 is directly sideshake 71 to be communicated with groove, and Fig. 1 is that the signal of another kind of form directly is communicated with outside (offering a pore at pressing plate 1 middle part gets final product).
Use when of the present invention, shown in Fig. 5,6, the shock isolating pedestal base 6(that with diameter, highly all is slightly less than finished product comprises steel plate 62, rubber 63 and following shrouding 64 earlier) insert in the forming cavity, with core rod 4 centering, realization circumferential registration.Again upper sealing plate 61 is fixedly connected on patrix bottom surface 31, the end face 21 of mould was realized highly location during fitted in the bottom surface 30 of patrix step circle immediately.At this moment, leave sideshake 71 between vibration isolating suspension base 6 and the middle mould 2 inner core faces, the end face of vibration isolating suspension base 6 the superiors' rubber 63 and be fixedly connected between upper sealing plate 61 bottom surfaces of patrix bottom surface 31 and leave bottom clearance 72.
After having good positioning, by annotate to press hole 320 in the middle mould 2 sideshake 71 and bottom clearance 72 in inject sizing material, by pressing plate 1 compacting, leave standstill, solidify, finalize the design.
After the steel plate of shock isolating pedestal product and rubber are thrown mould (promptly becoming aforesaid vibration isolating suspension base 6), the lifting patrix also drops into an amount of hot gluse size, lifting pressing plate in the patrix groove.During matched moulds, the sizing material in the patrix groove presses the hole to enter middle model cavity by the notes of waist shape, exists at steel plate thickness under the situation of deviation, has guaranteed that the product height in the middle model cavity is certain, product can not occur and lack material or the higher situation of product.The sizing material of protective layer is subjected to bigger extruding force, and the sizing material of protective layer and shock isolating pedestal product body bonding more firm guaranteed the quality of product effectively.
