Summary of the invention
Existing defective and problem provide a kind of electric capacity casing forming device with good insulation performance when solving in the prior art injection mo(u)lding of plastics electric capacity shell.
The technical scheme that the present invention is adopted for its technical problem of solution is: the electric capacity casing forming device with good insulation performance of the present invention comprises the dynamic model fuse, ALUMINUM SCREWS and cast gate mold insert, flow to the matching part of dynamic model fuse and ALUMINUM SCREWS bottom from the liquid plastics of cast gate mold insert ejaculation, an elasticity liftout attachment is set in the dynamic model fuse, the elasticity liftout attachment will form a space between ALUMINUM SCREWS bottom and the dynamic model fuse, the elasticity liftout attachment comprises movable jacking block, spring and support column, movable jacking block is pressed on the spring, support column supports movable jacking block and spring and locatees, movable jacking block upper end is a top bulge loop platform, be provided with a top in bulge loop platform centre position, top, withstand on the bottom surface of ALUMINUM SCREWS, movable jacking block lower end is a pressure side ring platform, centre position, pressure side Huan Tai lower end is provided with a spring locating shaft, spring is on the spring locating shaft, the spring upper end is pressed on the pressure side Huan Tai lower surface, the spring lower end is pressed on the support column upper surface, between movable jacking block and support column, form an elasticity elastic force, a location concave station also is set in the dynamic model fuse, support column is placed in the concave station of location, and pressure side ring platform and spring locating shaft and spring all are arranged in the concave station of location.
The invention has the beneficial effects as follows: compared with prior art, of the present invention have the electric capacity casing forming device employing activity jacking block of good insulation performance and an automatic ejecting structure of spring, when matched moulds, movable jacking block backs down certain interval between following ALUMINUM SCREWS of the effect of spring and dynamic model fuse, liquid plastics is when filling the gap in the process during injection moulding, after liquid plastics fills up the gap fully, the pressure of injecting fluid plastics is greater than the elastic force of spring, the pressure of injecting fluid plastics with the downward straightening of movable jacking block to contacting with support column, in the folding process of movable jacking block, disengage with ALUMINUM SCREWS, gap between ALUMINUM SCREWS and the dynamic model fuse is filled by liquid plastics, stopped the generation of " dew aluminium " phenomenon, behind product stripping, movable jacking block restPoses again under spring action, prepares the circulation of injection moulding next time, adopts the electric capacity casing forming device of this structure thoroughly to overcome " dew aluminium " phenomenon, reduce scrappage greatly, reduced production cost.
Description of drawings
Below in conjunction with the drawings and specific embodiments the electric capacity casing forming device with good insulation performance of the present invention is described further.
Fig. 1 is the structural representation of electric capacity casing forming device of the prior art.
The structural representation of Fig. 2 during for the matched moulds of the electric capacity casing forming device with good insulation performance of the present invention.
The structural representation of Fig. 3 after for the injection of the electric capacity casing forming device with good insulation performance of the present invention.
The specific embodiment
As shown in Figure 1 to Figure 3, the electric capacity casing forming device with good insulation performance of the present invention comprises ALUMINUM SCREWS 1, dynamic model fuse 2, cast gate mold insert 3 and elasticity liftout attachment.The elasticity liftout attachment comprises movable jacking block 20, spring 30 and support column 40; Movable jacking block 20 is pressed on the spring 30, and spring 30 is pressed on the support column 40, and 40 pairs of movable jacking blocks 20 of support column and spring 30 support and locate.Movable jacking block 20 upper ends are top bulge loop platform 21, be provided with a top 22 in bulge loop platform 21 centre positions, top, top 22 withstands on the bottom surface of ALUMINUM SCREWS 1, movable jacking block 10 lower ends are pressure side ring platform 23, centre position, pressure side ring platform 23 lower end is provided with a spring locating shaft 24, spring 30 is on spring locating shaft 24, spring 30 upper ends are pressed on pressure side ring platform 23 lower surfaces, spring 30 lower ends are pressed on support column 40 upper surfaces, spring 30 forms an elasticity elastic force between movable jacking block 20 and support column 40, a location concave station 6 also is set in the dynamic model fuse, location concave station 6 is in the dynamic model fuse 2, support column 40 is placed in the concave station 6 of location, and pressure side ring platform 23 and spring locating shaft 24 and spring 30 all are arranged in the concave station 6 of location.
As shown in Figure 2, when real work, when being in the matched moulds state, movable jacking block 20 upwards pushes up under the elastic force effect of spring 30, this moment, spring locating shaft 24 separated with support column 40, distance between spring locating shaft 24 lower surfaces and support column 40 upper surfaces is 1.2mm, top bulge loop platform 21 ejects dynamic model fuse 2, distance between pressure side ring platform 23 upper surfaces and the location concave station 6 is 0.6mm, top 22 on the top bulge loop platform 21 is top ALUMINUM SCREWS 1 upwards, makes and forms space 4 between ALUMINUM SCREWS 1 bottom and the dynamic model fuse 2.Liquid plastics start injection in the cast gate mold insert 3, liquid plastics begins to flow in the space 4.
As shown in Figure 3, after liquid plastics fills up gap 4 fully, the stuffing pressure of injecting fluid plastics is greater than the elastic force of spring 30, the pressure of injecting fluid plastics with movable jacking block 20 downward straightenings to contacting with support column 40, top 22 disengages with ALUMINUM SCREWS 1 in the folding process of movable jacking block 20, top bulge loop platform 21 keeps same horizontal line with dynamic model fuse 2, distance between pressure side ring platform 23 upper surfaces and the location concave station 6 is 1.8mm, spring locating shaft 24 is pressed on the support column 40, gap 4 between ALUMINUM SCREWS 1 and the dynamic model fuse 2 is by liquid plastics institute complete filling, this moment, an injection moulding process was finished, behind product stripping, movable jacking block 20 restPoses again under spring 30 effects, prepares the circulation of injection moulding next time, finishes injection moulding with this round moving up and down automatically.Adopt the electric capacity casing forming device of this new construction because the effect of movable jacking block 20 and spring 30 is arranged, the generation that can stop " dew aluminium " phenomenon fully reduces scrappage greatly, has reduced production cost.
, but should be understood that under the situation that does not break away from relevant protection domain defined by the claims that those skilled in the art can make change and/or revise according to embodiments of the invention describing the present invention property and nonrestrictive description.
