It is de- that such structure will not make guiding have a loose tongue.
Further, the runner is additionally provided with second level runner, second level runner on the length direction of cope plate
Diameter be equal to or less than the diameter of runner, second level runner connects runner and branch flow passage.Second level runner is for solution
The circulation problem of certainly longer-distance injection molding.
Further, the section of the branch flow passage is circle, and the surface of cope plate is arranged in half, the other half setting exists
In on the Die and mould plate that cope plate is close to setting, mutual pairing, forms circular runner between the two.The resistance of circular flow channel is small,
It can be suitble to convey more at a distance.
Further, the side of the forming cavity is provided with tiltedly guiding side pumping slider, and forming cavity is in corresponding shell structure
Edge forming have the forming area of sealing ring, be tiltedly oriented to the neighbouring outer side edges that forming area is set of side pumping slider.Side, which is taken out, to be slided
Block is that common side core-pulling structure exists, and is the release unit of the sealing ring of the outer side edges solved herein, has protection sealing ring complete
Whole effect.
The other component of mold uses the structure of existing mold, does not repeat herein.
The utility model compared with prior art, has the following advantages that and effect: the present apparatus is a kind of in water heater
With the mode device of fixing sealing ring of injection molding on shell, by glue-feeder and into the improvement of glue mode, so that soft
Sealing strip is directly molded on the encapsulated plastic casing to hard, without installation by hand, so that production efficiency is effectively promoted,
And human cost is reduced for enterprise.The encapsulated technique of this kind innovation simultaneously can also be obviously improved the yields and sealing effect of product
Fruit guarantees electric equipment products safety in utilization, has good market prospects.Multiple spot Shooting Technique is specifically used, is solved very well
It is insufficient that pressure is penetrated caused by product length of flow is too long, sealing strip size is different, thus the problem of influencing sealing effect, yields
It is substantially improved.The improvement of the injection molding into glue into glue mode is tried by being shifted into glue point overlap joint, using the injection mold of normal length
Length can be met away from the requirement of strip gasket Shooting Technique, can effectively reduce Mold Making cost.Bilayer is done to single sealing strip
Bit architecture design is sealed, so that soft sealing strip is closely coated on the plastic casing of hard, to improve product
Sealing effect.
