The step of heat fusing；（3）With Screw Extrusion and point four sections of steps being injected into mould cavity；（4）Three sections of molding steps of pressurize
Suddenly；（5）The step of discharging.
The production technology of connection box for motor of the present invention, step（1）In drying temperature be 120-130 DEG C.
The production technology of connection box for motor of the present invention, step（2）In fusion temperature be 220-260 DEG C.
The production technology of connection box for motor of the present invention, step（3）Middle first segment injection position is screw rod whole apart from stroke
When at point 40mm, pressure 9.8Mpa, rotating speed 80r/min, temperature are 245 DEG C；Second segment injection position is screw rod in distance
When at the 20mm of stroke end, pressure is 8.0 Mpa, and rotating speed is 56 r/min, and temperature is 240 DEG C；3rd section of injection position is spiral shell
For bar when at the 6mm of stroke end, pressure is 6.0 Mpa, and rotating speed 48r/min, temperature is 235 DEG C；4th section of injection position
Screw rod is set to when reaching stroke end, pressure is 4.5 Mpa, and rotating speed is 38.4 r/min, and temperature is 229 DEG C.
The production technology of connection box for motor of the present invention, step（3）In four sections injection total times be 2.2s.
The production technology of connection box for motor of the present invention, the step（3）In mold be a mould double cavity structure.
The production technology of connection box for motor of the present invention, step（4）In pressurize temperature for 222 DEG C, first segment dwell pressure
For 9.5 Mpa, rotating speed is 136 r/min, time 2s；Second segment dwell pressure is 6.0Mpa, and rotating speed is 19.2 r/min,
Time is 1.9s；3rd section of dwell pressure is 4.0Mpa, and rotating speed is 16 r/min, time 1s.
The production technology of connection box for motor of the present invention, five steps are completed in screw injection molding machine.
The beneficial effects of the invention are as follows：
The present invention using PA master batches as raw material, after the drying through specific temperature, rotating speed and pressure carry out four sections be molded and
Three sections of pressurizes, the connection box for motor finally made is compared with the terminal box made of existing production method using similary PA master batches
Hardness and strength all highers.Therefore only need that using lower-cost PA master batches the higher electricity of mass can be produced in production
Machine terminal box, greatly reduces production cost.
Specific embodiment
The present invention is described in further detail now.
A kind of production cost is low, and the life of the higher connection box for motor of the connection box for motor hardness and strength produced
Production. art carries out following five steps in screw injection molding machine：（1）The step of PA master batches are dried at 120-130 DEG C；
（2）The step of melting is heated to master batch at 220-260 DEG C；（3）Using the mold of a mould double cavity structure, with Screw Extrusion and divide
Four sections are injected into mould cavity, and each section is injected into two die cavitys simultaneously：First segment injection position for screw rod away from
During from the 40mm of stroke end, pressure 9.8Mpa, rotating speed 80r/min, temperature are 245 DEG C；Second segment injection position is spiral shell
For bar when at the 20mm of stroke end, pressure is 8.0 Mpa, and rotating speed is 56 r/min, and temperature is 240 DEG C；3rd section of injection
Position for screw rod when apart from the 6mm of stroke end at, pressure be 6.0 Mpa, rotating speed 48r/min, temperature be 235 DEG C；4th
Section injection position for screw rod when reaching stroke end, pressure be 4.5 Mpa, rotating speed be 38.4 r/min, temperature be 229 DEG C；
And above-mentioned four sections of injection total times are 2.2s；（4）Three sections of pressurizes shaping at a temperature of 222 DEG C the step of：First segment pressurize pressure
Power is 9.5 Mpa, and rotating speed is 136 r/min, time 2s；Second segment dwell pressure is 6.0Mpa, and rotating speed is 19.2 r/min,
Time is 1.9s；3rd section of dwell pressure is 4.0Mpa, and rotating speed is 16 r/min, time 1s；（5）Terminal box in two die cavitys
