Description
Technical field
The utility model relates to a kind of cold runner injection device, belongs to rubber seal field.
Background technology
Along with the expansion of extraordinary fluorubber application, the method shaping to fluorubber proposes the requirement of injection.General Purpose Rubber injection technique is very ripe, but it is slow to there is flowing in branching process during fluorubber injection, the problem that reducing place flow passage resistance force of waterproof is large, make production process very unstable, the injection limiting fluorubber is produced, because reasonably the flow dividing structure of design runner, can solve fluorubber and flow slowly in runner, the problem that resistance is large.Moreover fluorubber carries out injecting and shunting under the pressure of equipment, in existing technology, bottom surface, glue feeding opening hole is horizontal plane, and plastic hole is isometrical circular hole, causes fluororubber shunt slow and the problem such as uneven and in runner resistance is large.
Summary of the invention
The purpose of this utility model is to provide a kind of Novel cold runnerless injection device, and during to solve fluorubber injection, owing to being horizontal plane at the bottom of glue feeding opening hole, plastic hole is isometrical circular hole, makes fluorubber flowing in branching process slow, the large problem of runner internal resistance.
The utility model solves the technical scheme that its technical problem adopts: a kind of Novel cold runnerless injection device, it comprises flow distribution plate, described flow distribution plate is rectangular slab, the plate face of described flow distribution plate is processed with respectively four glue feeding openings, 16 sprues, 16 runners, 64 branch flow passages, 64 plastic holes and multiple fixing holes; Described four glue feeding openings are symmetrical arranged with flow distribution plate length direction center line and width center line respectively; The periphery of each glue feeding opening is provided with four sprues; These four sprue one end are communicated with described glue feeding opening, and these four sprue other ends are with four runner one_to_one corresponding and be communicated with; The two ends of each runner are communicated with two branch flow passages; Each branch flow passage is communicated with plastic hole, and the thickness of the through flow distribution plate in plastic hole is arranged, and the bottom of each plastic hole is funnel shaped; The bottom of each glue feeding opening is cone shape.
The beneficial effects of the utility model are:
1. the utility model devises the conical structure of 120 ° in shunting place of multiple glue feeding opening rubber, is beneficial to the flowing of rubber Quick uniform.
2. the utility model funnel structure of being provided with 90 ° at multiple plastic hole place, is beneficial to transition between major diameter and minor diameter, and then reduces the resistance of sizing material in runner, accelerate the flowing velocity of sizing material.
3. the utility model is provided with multiple fixing hole on flow distribution plate, is convenient to the connection of this device and process equipment, easy to connect, firmly.
4. the utility model is provided with multiple plastic hole on flow distribution plate, is beneficial to and guides fluorubber plastic emitting.

Fig. 1 is the structural profile schematic diagram of a kind of Novel cold runnerless injection device of the present utility model.
Fig. 2 is the structural representation of a kind of Novel cold runnerless injection device of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Fig. 1 ~ Fig. 2, a kind of Novel cold runnerless injection device, it comprises flow distribution plate 3, described flow distribution plate 3 is rectangular slab, the plate face of described flow distribution plate 3 is processed with respectively four glue feeding openings 1,16 sprue, 6,16 runners, 5,64 branch flow passages, 7,64 plastic holes 2 and multiple fixing hole 4; Described four glue feeding openings 1 are symmetrical arranged with flow distribution plate 3 length direction center line and width center line respectively; The periphery of each glue feeding opening 1 is provided with four sprues 6; These four sprue 6 one end are communicated with described glue feeding opening 1, and these four sprue 6 other ends are with four runner 5 one_to_one corresponding and be communicated with; The two ends of each runner 5 are communicated with two branch flow passages 7; Each branch flow passage 7 is communicated with plastic hole 2, and the thickness of the through flow distribution plate 3 in plastic hole 2 is arranged, and the bottom of each plastic hole 2 is funnel shaped; The bottom of each glue feeding opening 1 is cone shape.
Further, as shown in Figure 2, described four sprues 6 are along the uniform setting of periphery of glue feeding opening 1.Setting like this, makes plastic emitting flow evenly, improves plastic emitting efficiency.
Further, as shown in Figure 1, the funnel shaped coning angle of the bottom of described plastic hole 2 is 90 °.
Further, as shown in Figure 1 and Figure 2, the material of described flow distribution plate 3 is p20 mould steel.Setting like this, improves the intensity of flow distribution plate 3, and flow distribution plate 3 is not yielding and damage.
Further, as shown in Figure 1, the coning angle of the cone shape of the bottom of described glue feeding opening 1 is 120 °.
As shown in Figure 1 and Figure 2, during use, flow distribution plate 3 is arranged on dull and stereotyped injection vulcanizer by multiple fixing hole 4, fluorubber is injected under the pressure of equipment in glue feeding opening 1, and shunt through sprue 6, runner 5 and branch flow passage 7, finally flow in plastic hole 2, and flow in fluorubber mould by plastic hole 2, make fluorubber mould molding.
