Abstract
The invention provides an injection molding method of a PWM (Pulse Width Modulation) controller shell body and metal pins, which comprises the following steps of: A, integrating a plurality of molded metal pins to be separated; mutually connecting and punching an integral metal piece by a plurality of connecting blocks; B, positioning and putting the punched integral metal piece into a mould for molding the PWM controller shell body for injection molding; and C, removing the connecting blocks for connecting the metal pins for separating the metal pins. Compared with the prior art of the separation injection of the metal pins, the injection molding method of the PWM controller shell body and the metal pins can reduce the positioning and holding quantity of the pins, simplify the installation of the pins, enhance precision, reduce technological difficulty, shorten injection time, simplify subsequent processing technology, and reduce the total cost of products.
Description
Technical field
The present invention relates to a kind of preparation method of electric component, relate in particular to the injection molding forming method of a kind of PWM controller housing and metal pins.
Background technology
In the design of PWM controller, the power circuit part generally needs by bigger electric current, so if power circuit is arranged on the pcb board, then need adopt bigger live width, this will cause the control panel design volume to become big, increase the wiring difficulty; Simultaneously, owing to adopt the PWM pulse modulation technology, the electromagnetic interference that power circuit produces also can influence the operate as normal of electronic device on the whole plate.Therefore, power circuit need be separated with pcb board usually, wherein a kind of separation method is to utilize metal pins to be connected across on the pcb board, realizes the layout of power circuit.The PWM controller is a single input dual output structure, and total polylith metal pins need embed in the housing when injection moulding.But because each pin is independently, thus when injection moulding, need add a plurality of positioning clamping, and by locating hole and pin positioning and fixing.In addition, the mounting process more complicated of a plurality of metal pins in mould, installation process also goes wrong easily.After the depanning,, may cause the position between each metal pins to change, reduce precision because there is cooling strain in housing.These shortcomings all will increase the technological requirement of injection moulding and processing PCB plate.
Summary of the invention
Purpose of the present invention is exactly in order to provide a kind of cost is low and welding process requirement the is lower PWM controller housing and the injection molding forming method of metal pins.
In order to achieve the above object, the present invention has adopted following technical scheme: the injection molding forming method of a kind of PWM controller housing and metal pins may further comprise the steps:
A, the metal pins that needs after a plurality of moulding to separate is carried out integration design, interconnect the as a whole metalwork of drawing by a plurality of contiguous blocks;
B, the mould of moulding PWM controller housing, injection mo(u)lding are put in the unitary piece of metal of drawing location;
C, a plurality of contiguous blocks that will connect each metal pins are removed, and realize the separation of each metal pins.
Described a plurality of metal pins comprises first pin, second pin, the 3rd pin, the 4th pin, the 5th pin and the 6th pin; Described a plurality of contiguous block comprises first contiguous block, second contiguous block, the 3rd contiguous block, the 4th contiguous block, the 5th contiguous block, the 6th contiguous block and the 7th contiguous block; First contiguous block is connected between first pin and second pin, second contiguous block is connected between second pin and the 3rd pin, the 3rd contiguous block connects and the 4th contiguous block is connected between the 3rd pin and the 4th pin, the 5th contiguous block is connected between first pin and the 4th pin, the 6th contiguous block is connected between first pin and the 5th pin, and the 7th contiguous block is connected between first pin and the 6th pin.
PWM controller housing of the present invention separates injection moulding with the injection molding forming method of metal pins with the metal pins of original technology to be compared, and can reduce pin positioning clamping quantity, simplify pin and install, improve precision, reduce technology difficulty, shorten injection time, simplify the postorder processing technology, reduce the product totle drilling cost.

The specific embodiment
The injection molding forming method of PWM controller housing of the present invention and metal pins is, at first the metal pins that needs after a plurality of moulding to separate carried out the integration design, interconnects drawing by a plurality of contiguous blocks and is as shown in Figure 1 unitary piece of metal 1.A plurality of metal pins comprise first pin 11, second pin 12, the 3rd pin 13, the 4th pin 14, the 5th pin 15 and the 6th pin 16.A plurality of contiguous blocks comprise first contiguous block 21, second contiguous block 22, the 3rd contiguous block 23, the 4th contiguous block 24, the 5th contiguous block 25, the 6th contiguous block 26 and the 7th contiguous block 27.Wherein, first contiguous block 21 is connected between first pin 11 and second pin 12, second contiguous block 22 is connected between second pin 12 and the 3rd pin 13, the 3rd contiguous block 23 connects and the 4th contiguous block 24 is connected between the 3rd pin 13 and the 4th pin 14, the 5th contiguous block 25 is connected between first pin 11 and the 4th pin 14, the 6th contiguous block 26 is connected between first pin 11 and the 5th pin 15, and the 7th contiguous block 27 is connected between first pin 11 and the 6th pin 16.
Then unitary piece of metal 1 location of drawing is put into the mould of moulding PWM controller housing, injection mo(u)lding; Obtain structural member as shown in Figure 2, shown in Fig. 2,2 is plastic casing.
A plurality of contiguous blocks 21,22,23,24,25,26,27 that will connect each metal pins are at last removed, and realize the separation of each metal pins 11,12,13,14,15,16.Obtain structural member as shown in Figure 3.
Method of the present invention mainly is applicable to the injection moulding of the plastic casing that needs embedded a plurality of separating metal spares.As be with a plurality of metal pins to draw, and need be embedded in the PWM controller in the plastic casing.
