An injection hole is disposed on the front side of the upper template, and a flow rubber groove is disposed on the rear side of the upper template, besides, the flow rubber plate is provided with a plurality of injection holes corresponding to the flow rubber groove. The middle die cavity is provided with a mould cavity corresponding to the injection hole, and parting die drawing plates are disposed on two sides of the mould cavity, besides, an ejector plate is disposed on the outer side of the middle mould cavity. The lower template is provided with a mould cavity bottom plate corresponding to the mould cavity, and mould cavity fixing blocks are disposed on two sides of the mould cavity bottom plate. In the utility model, the cementation of the glue material and the steel plate is firm by using the ejection mould, and the degumming problem is solved. The utility model has advantages of simple operation, high production efficiency, stable product quality and good damping effect.
Description
Technical field
The utility model relates to a kind of rubber injection mold, particularly a kind of injecting molding die of road roller snubber block.
Background technology
Road roller has vibrating device mostly, produces vibration when pressing the road, increases work efficiency greatly in tamping road bed or road surface, and in order to guarantee the comfortableness of driver's cabin, damping device becomes the requisite vitals of road roller.Disclosed compactor structure such as patent CN2509214Y, CN2509215Y, snubber block has outstanding effect.
The structure of road roller snubber block such as Fig. 8 and shown in Figure 9 comprise rubber cylinder A, and the metal plate B at two ends.At present the road roller snubber block adopts the form processing of mold pressing mostly, waste time and energy, and processing cost height, and quality instability, and also the most outstanding shortcoming is that the metallic plate at rubber and two ends is bonding insecure, has degumming phenomenon, causes the quality instability of product.Therefore, seek a kind of novel forming method and become the task of top priority.Though injection molding of rubber technology at present commonly used, by with rubber with the inserts moulding, can solve the degumming problem that exists between block rubber and the inserts, the most complex structure of injection molding of rubber mould, folding mould difficulty causes production efficiency to reduce.
Summary of the invention
The purpose of this utility model is to solve the defective that existing snubber block mould exists, and provides that a kind of rubber and steel plate are connected firmly, the injecting molding die of road roller snubber block simple to operate.
The utility model solves its technical problem and adopts following technical scheme: according to road roller snubber block injecting molding die of the present utility model, comprise cope match-plate pattern, gummosis plate, middle model cavity and lower bolster, wherein the front of cope match-plate pattern is provided with injection orifice, the back side is provided with spew groove, the gummosis plate is provided with a plurality of hole for injecting glue corresponding with spew groove, middle model cavity has and the corresponding die cavity of hole for injecting glue, the die cavity both sides are provided with branch die drawing plate, the arranged outside liftout plate of middle model cavity, lower bolster has and the corresponding die cavity base plate of die cavity, and die cavity base plate both sides are provided with the die cavity fixed block.
Described die cavity fixed block projects upwards, and inserts in the cavity that divides die drawing plate both sides during matched moulds.Middle model cavity preferably comprises two die cavities.Described injection orifice in the cope match-plate pattern communicates with spew groove.
The beneficial effects of the utility model are: the metallic plate at (1) rubber cylinder and two ends is bonding firmly, has solved degumming phenomenon; (2) simple to operate, saved production cost; (3) steady quality of product, good damping effect.

The specific embodiment
In order further to set forth the obtained beneficial effect of the utility model; below in conjunction with accompanying drawing and preferred embodiment; structure, feature and operational means to the snubber block injection molding of proposition in the application are elaborated; but should be noted in the discussion above that this novel scope required for protection is not limited in this.
Fig. 8 and 9 is depicted as the schematic diagram of road roller snubber block.Snubber block 10 comprises the metal plate B at rubber cylinder A and two ends thereof.
Accompanying drawing 1-7 has then provided the schematic diagram of the corresponding injection molding of the above-mentioned road roller snubber block of moulding.
Accompanying drawing has provided the structure of a kind of preferred embodiment of the utility model, pressure injection mold comprises: cope match-plate pattern 1, lower bolster 4, gummosis plate 2 between bolster and middle model cavity 3, wherein the front of cope match-plate pattern 1 is provided with injection orifice 5, the back side is provided with spew groove 6, injection orifice 5 communicates with spew groove 6, gummosis plate 2 is provided with a plurality of hole for injecting glue 7 corresponding with spew groove 6, middle model cavity 3 has and the corresponding die cavity 9 of hole for injecting glue, preferred embodiment of the present utility model is 2 die cavities, the die cavity both sides are provided with branch die drawing plate 8, the outside of middle model cavity 3 has liftout plate 11, lower bolster 4 has and die cavity 9 corresponding die cavity base plates 13, and die cavity base plate 13 both sides are provided with outstanding die cavity fixed block 12.
During moulding, the steel plate that will have through hole places die cavity base plate 13 and die cavity 9 respectively, cope match-plate pattern 1, gummosis plate 2, middle model cavity 3 and lower bolster 4 be matched moulds successively, die cavity fixed block 12 in the lower bolster 4 inserts in the cavity that divides die drawing plate 8 outsides, thereby makes die cavity 9 fixing, uses the injection (mo(u)lding) machine (not shown) that sizing material is injected from injection orifice 5, sizing material is by spew groove 6 shuntings, flow into the die cavity 9 from hole for injecting glue 7, after the sizing material injection was finished, locked mode also used vulcanizing press to vulcanize.Because sizing material and steel plate are subjected to briquetting pressure jointly, sizing material and upper and lower sides steel plate are bonding firmly, degumming phenomenon can not take place.
After the moulding, open mould, the liftout plate 11 of the both sides by middle model cavity 3 ejects middle model cavity 3, the branch die drawing plate 8 of die cavity both sides is outwards pulled out respectively, thereby open die cavity 9, takes out the snubber block 10 of moulding, operates very simple.
