Abstract
The present invention relates to a kind of actuator brush holder forming method, it comprises the steps: to utilize blanking die to carrying out blanking, obtains the actuator brush holder skeleton of metal；Actuator brush holder skeleton is put in punching die, it is punched out, desired location is formed hole；Actuator brush holder skeleton after punching is bent to reservation shape；Actuator brush holder skeleton is molded in advance, forms the interior injection molded layers being connected with actuator brush holder skeleton；The precalculated position of actuator brush holder skeleton and interior injection molded layers is cut off；Carry out quadric injection mould on actuator brush holder skeleton after severance and interior injection molded layers, form actuator brush holder body；The electricity component such as welding lead, thermal cut-off, conducting strip on actuator brush holder body, forms actuator brush holder.The actuator brush holder forming method of the present invention passes through twice injection molding forming method, quadric injection mould again after actuator brush holder skeleton and interior injection molded layers being initially switched off, and can greatly reduce situation exposed metal/bare metal occur.
Description
Technical field
The present invention relates to injection mo(u)lding field, especially relate to a kind of actuator brush holder forming method.
Background technology
Actuator brush holder is the vitals in dynamo governor, is used for installing brush.Due to when injection mo(u)lding actuator brush holder, the metal connecting sheet deformation that the powerful impulsive force that injection produces is easily caused on actuator brush holder, therefore people typically thrust hole etc., for by metal connecting sheet firm position at actuator brush holder design injection centre hole, metal connecting sheet.In prior art when manufacturing actuator brush holder, it is first injection mo(u)lding, then ad-hoc location is thrust, form actuator brush holder.But, owing to being molded centre hole, thrusting the existence in hole, the actuator brush holder after molding easily occurs that after thrusting metal is exposed from this some holes, causes easily occurring short circuit, burns out electromotor.Therefore, the forming method made new advances how is designed, enabling avoid actuator brush holder that exposed metal/bare metal occurs, become the technical problem that those skilled in the art are urgently to be resolved hurrily.
Summary of the invention
It is an object of the invention to for the problems referred to above, it is provided that a kind of actuator brush holder forming method, solve the technical problem existing for prior art.
For reaching above-mentioned purpose, present invention employs following technical proposal: a kind of actuator brush holder forming method, it comprises the steps:
Blanking: utilize blanking die to carrying out blanking, obtain the actuator brush holder skeleton of metal；
Punching: be put in punching die by actuator brush holder skeleton, be punched out it, forms hole in desired location；
Bending: the actuator brush holder skeleton after punching is bent to reservation shape；
Pre-injection: be molded in advance on actuator brush holder skeleton, forms the interior injection molded layers being connected with actuator brush holder skeleton；
Cut off: the precalculated position of actuator brush holder skeleton and interior injection molded layers is cut off；
Quadric injection mould: carry out quadric injection mould on actuator brush holder skeleton after severance and interior injection molded layers, forms actuator brush holder body；
Welding: the electricity component such as welding lead, thermal cut-off, conducting strip on actuator brush holder body, forms actuator brush holder.
In above-mentioned actuator brush holder forming method, it is preferable that in pre-injection step with cut off between step, also include auxiliary member forming step: molding runners, projection and groove on actuator brush holder skeleton after pre-injection mo(u)lding and interior injection molded layers.
In above-mentioned actuator brush holder forming method, it is preferable that also include testing procedure between quadric injection mould step and welding step: the conduction of the circuit in test actuator brush holder is the most qualified.
In above-mentioned actuator brush holder forming method, it is preferable that in welding step, the method for welding is means of spot welds.
The actuator brush holder forming method of the present invention passes through twice injection molding forming method, quadric injection mould again after actuator brush holder skeleton and interior injection molded layers being initially switched off, and can greatly reduce situation exposed metal/bare metal occur so that the quality of actuator brush holder is increased dramatically.
Detailed description of the invention
The actuator brush holder forming method that the embodiment of the present invention provides comprises the steps:
Blanking: utilize blanking die to carrying out blanking, obtain the actuator brush holder skeleton of metal；
Punching: be put in punching die by actuator brush holder skeleton, be punched out it, forms hole in desired location；
Bending: the actuator brush holder skeleton after punching is bent to reservation shape；
Pre-injection: be molded in advance on actuator brush holder skeleton, forms the interior injection molded layers being connected with actuator brush holder skeleton；
Cut off: the precalculated position of actuator brush holder skeleton and interior injection molded layers is cut off；
Quadric injection mould: carry out quadric injection mould on actuator brush holder skeleton after severance and interior injection molded layers, forms actuator brush holder body；
Welding: the electricity component such as welding lead, thermal cut-off, conducting strip on actuator brush holder body, forms actuator brush holder.Preferably, welding manner is means of spot welds.
Preferably, in pre-injection step with cut off between step, it is also possible to include auxiliary member forming step: molding runners, projection and groove on actuator brush holder skeleton after pre-injection mo(u)lding and interior injection molded layers.When runner can make quadric injection mould, plastics flowing is the most unobstructed, and projection and groove can make the plastic layer of quadric injection mould the most firm with the combination of actuator brush holder skeleton and interior injection molded layers.
Preferably, between quadric injection mould step and welding step, testing procedure is also included: the conduction of the circuit in test actuator brush holder is the most qualified.
The actuator brush holder forming method of the present invention passes through twice injection molding forming method, quadric injection mould again after actuator brush holder skeleton and interior injection molded layers being initially switched off, and can greatly reduce situation exposed metal/bare metal occur so that the quality of actuator brush holder is increased dramatically.
Specific embodiment described herein is only to present invention spirit explanation for example.Described specific embodiment can be made various amendment or supplements or use similar mode to substitute by those skilled in the art, but without departing from the spirit of the present invention or surmount scope defined in appended claims.
Although the most more employing the terms such as actuator brush holder, actuator brush holder skeleton, interior injection molded layers, but it is not precluded from using the probability of other term.Use these terms to be only used to more easily to describe and explain the essence of the present invention；It is all contrary with spirit of the present invention for being construed as any additional restriction.
