Step c is carried out after going out and starts the cycle over production.
In a kind of foregoing electromagnetic wire coil injection moulding process, ejection is arranged with the mold insert push rod in the step b and resets bullet
Spring, ejection back-moving spring are compressed, are then resetted in step d, liftout plate is moved down automatically in stepb.
In a kind of foregoing electromagnetic wire coil injection moulding process, when being molded in the step f, mold insert and lower mold fixed plate it
Between stress spring row buffering is entered to the crimp force that magnetic stripe is subject to.
According to the injection mold constructed by a kind of foregoing electromagnetic wire coil injection moulding process, including upper mould, set below upper mould
It is equipped with lower mold fixed plate；Mold insert push rod is connected with lower mold fixed plate, the both ends of mold insert push rod are connected to fixed magnetic
The mold insert and liftout plate of bar, mold insert is between upper die and lower die fixed plate.
In foregoing injection mold, ejection back-moving spring is also arranged with the mold insert push rod, ejection back-moving spring is located at
Between lower mold fixed plate and liftout plate, mold insert is facilitated to retract automatically original position.
In foregoing injection mold, the position of the mold insert is corresponding with the position of the magnetic stripe on drum, can put simultaneously
Put all magnetic stripes on drum.
In foregoing injection mold, stress spring is provided between the mold insert and lower mold fixed plate, buffering can be played
Effect, place magnetic stripe fracture.
In foregoing injection mold, the stress spring is provided with two, and is located at the both ends of mold insert bottom surface respectively；It is described
Mold insert push rod is connected with the middle part of mold insert bottom surface；Mold insert uniform force can be made, prevent magnetic stripe position from off normal occur, improve product
Quality.
In foregoing injection mold, the opening position that mold insert is corresponded in the lower mold fixed plate is provided with die cavity.
In foregoing injection mold, the height of the mold insert push rod is more than the height of lower mold fixed plate, can be completely by edge
Part ejects lower mold fixed plate, facilitates the placement of magnetic stripe to fix, convenient use.
Compared with prior art, present invention improves over existing electromagnetic wire coil injection moulding process and injection mold, setting is passed through
Mold insert fixes the position of magnetic stripe, can directly wrap magnetic stripe in injection and be moulded in support, realizes support and magnetic stripe
Integral type is molded, and is eliminated the bonding of glue, is not only increased production efficiency, also reduces production cost；Ejected by setting
Plate and mold insert push rod, mold insert can be ejected to lower mold fixed plate, eject die cavity, make the empty avoiding space around mold insert big and without dry
Relate to, facilitate placement and fixation of the magnetic stripe on mold insert, additionally it is possible to eject product after completing to be molded, convenient use.In addition, this
Invention is also provided with ejecting back-moving spring, and mold insert can be made after the completion of taking out product, placing magnetic stripe in ejection back-moving spring
Restoring force effect is lower to be returned, and is made mold insert automatically in retraction die cavity, is further facilitated use；By setting stress spring 8 can also
The crimp force born during to injection on magnetic stripe enters row buffering, prevents magnetic stripe to be broken, and improves product qualification rate；By setting two companies
The stress spring at mold insert bottom surface both ends is connect, and mold insert push rod is made mold insert uniform force, prevent magnetic stripe with being connected in the middle part of mold insert
There is off normal, improve product quality.Therefore, the present invention can not only improve production efficiency, also with production cost it is low, use
The advantages of convenient, product qualification rate height and good product quality.
