A quarter bisector and a quarter bisector of width be crossed to form a point position.Conversely, the long width of diagonal position
A quarter line is crossed to form another point position.For example 1 product length of storage battery shell is 200cm, width is
100cm, then make a horizontal line section, width 25cm places one vertical curve of work at the anterior length 50cm of product；Product other one
While at angular length 50cm make a horizontal line, wide 25cm place make a vertical curve, intersecting position formation two point positions.Two hot mouths 2
It is corresponding positioned at the position of the two point positions respectively.In addition, muscle is avoided in the position of two hot mouths 2 at the same time into glue point position at this time
Position, and between muscle position and muscle position.So as to be conducive to the balance plastic emitting of hot mouth, mould strength is ensure that so as to extend mould
Service life.
Optionally embodiment, two hot mouths 2 and the muscle position stagger setting of accumulator housing 1.
Specifically, that is, the setting position of hot mouth 2 is between two muscle positions.By by the setting of two hot mouths 2
Position and the muscle dislocation of accumulator housing 1 are opened, so as to avoid the unbalanced of muscle position glue amount, and then avoid causing muscle position starved or muscle
The problem of position offset.
Optionally embodiment, hot mouth 2 and driving mechanism set identical quantity.
Specifically, as shown in Figure 1, hot mouth 2 and driving mechanism are correspondingly arranged, each driving mechanism drives a hot mouth to open
Or close, so as to fulfill accurate driving.
Further, driving mechanism includes cylinder 41 and needle 42.The top of needle 42 and the output terminal of cylinder 41 are fixed
Installation.The lower part of needle 42 wears hot mouth 2 and drives hot mouth 2 to be turned on and off.Cylinder 41 is connected with the upper end of flow distribution plate 3.
Specifically, as shown in Figure 1 to Figure 3, wherein Fig. 3 is B-B schematic cross-sectional views in Fig. 1, that is to say, that Fig. 3 is shunting
The B-B sectional views of plate 2.The top of needle 42 is fixedly connected with the piston rod of cylinder 41, so that the up and down motion driving of piston rod
The up and down motion of needle 42 so as to fulfill unlatching of the needle to hot mouth 2 closing.
Optionally embodiment, hot mouth 2 are arranged to four or eight.Each two hot mouth 2, which corresponds to, is located at an electric power storage
The top surface of pond housing 1.
Specifically, as shown in Figure 1 to Figure 3, since two hot mouths 2 correspond to an accumulator housing 1, as hot mouth 2 is arranged to
Four or eight, then it can once realize the injection molding to two or four accumulator housing 1.So as to save processing cost.
Further, runner 30 is offered in flow distribution plate 3.Runner 30 includes preceding runner 31, connecting passage 32 and rear runner
33.The front and back end of connecting passage 32 corresponds to the center for connecting preceding runner 31 and rear runner 33 respectively.Preceding runner 31 is with being located at
The hot mouth 2 of 1 top surface of accumulator housing front portion connects.Runner 33 is connected with the hot mouth 2 positioned at 1 top surface rear portion of accumulator housing afterwards.
The center of connecting passage 32 is connected with injection nozzle 5.
Specifically, two accumulator housings 1 are molded at the same time as shown in figure 3, can use.Preceding runner 31 and rear runner 33 divide
Not Cai Yong yi word pattern runner, offer the circulation for connecting hot mouth 2 respectively in the left and right ends of preceding runner 31 with rear runner 33
Hole, colloid are flowed into hot mouth 2 from recirculation hole.Connecting passage 32 is obliquely installed, so as to make the rear and front end of connecting passage 32
Correspondence is connected with the center of preceding runner 31 respectively and the center of rear runner 33 connects.
Further, it is identical to the colloid flow of two hot mouths 2 respectively from the center of connecting passage 32.
Specifically, colloid flow, that is to say, that the distance that colloid flows through.Colloid divides from the center of connecting passage 32
Not to upper runner 31 and lower flow channel 33, so that corresponding flow in two hot mouths 2.Due to the center of connecting passage 32
Connected with injection nozzle 5, and it is identical to the colloid flow of two hot mouths 2 respectively from the center of connecting passage 32, so as to
Colloid is reached hot mouth 2 at the same time, and then balance the purpose of plastic emitting.
As shown in figure 3, the side of preceding runner 31, connecting passage 32 and rear runner 33 is installed with plug 34 respectively.It is stifled
First 34 setting can prevent flow distribution plate leak adhesive.
As shown in figure 4, wherein Fig. 4 is C-C schematic cross-sectional views in Fig. 1, that is, remove the top surface of the flow distribution plate 3 of cylinder 41
Schematic diagram.Disk line 35 is embedded with respectively in the top and bottom (not shown) of flow distribution plate 3.Disk line 35 is used for flow distribution plate
Colloid heating in 3, so that colloid keeps constant temperature in injection flow distribution plate 3, strengthens mobility.Disk line 35 is around flow distribution plate 3
On open up set for the recirculation hole that is connected respectively with hot mouth 2 and injection nozzle 5.
As shown in figure 5, Fig. 5 is flow distribution plate schematic cross-sectional view of the present invention using eight hot mouths.Every two in eight hot mouths 2
A hot mouth 2 corresponds to an accumulator housing 1 respectively, so that the injection molding of four accumulator housings 1 can be realized.Wherein, four
Accumulator housing 1 is laid in two row, two row, and injection nozzle 5 is located at the center of flow distribution plate 3, and connects with the center of runner 30
It is logical, so as to make the distance that colloid flows to each hot mouth 2 respectively in runner 30 identical, and then make the synchronization of each hot mouth 2
Plastic emitting achievees the purpose that balanced plastic emitting.
The purpose of second aspect of the present invention is to provide a kind of two point form injecting glue hot flow path injection moulding process, by such as of the invention
The first convenient storage battery shell two point form injecting glue hot runner structure is realized, is included the following steps.
