A kind of 2. mold use method as claimed in claim 1, it is characterised in that：The mold use method includes following
Step：
1) mould mold filling
When mould closes, treat that plastics fill in die cavity, die sinking is waited after cooling；
2) internal thread is stripped
The demoulding of product depth tooth internal thread relies primarily on lower core package to realize, lower core package Leave out thread principle is：Ejection
Before beginning, lower core package is by lower core block one (300), lower core block two (301), lower core block three (302), lower core block four
(303), lower core block five (304), lower core block six (305), central slide body (306) composition, wherein, core block one (300),
Lower core block three (302), lower core block five (304) are one group and the cooperation of T angles T-slot, lower core on central slide body (306)
Block two (301), lower core block four (303), lower core block six (305) are one group and R angle T-slots on central slide body (306)
Coordinate, central slide body (306) is installed on lower core contiguous block (315), if Down-Up promote simultaneously lower core block one~
Six, in the case that central slide body (306) is fixed, lower core block one-six is along T-shaped on central slide body (306)
When groove moves upwards, two groups of downslide blocks are due to central slide body (306) inclination angle T/R difference, on centripetal direction
Different acceleration is obtained,, will between adjacent sliders body because centripetal acceleration is different although vertical direction speed is the same
There is gap, integrated model motion process is as follows：During ejection, injection machine push rod is by scraper push pedal (221), scraper push pedal cover plate
(230) motion upwards, due to spacing drag hook (231), the effect of spacing control small slide block (224), small slide block spring (225), scrape
Expect that push pedal (221) and scraper push pedal cover plate (230) will drive core push pedal cover plate (222), core push pedal (226) to transport upwards together
It is dynamic；Scraper push pedal (221) will promote material scraping plate (210) to move upwards by material scraping plate release link (212), core push pedal (226)
Central push pedal (219) will be promoted to move upwards by lower link bar (218), central push pedal (219) will promote upper core (313) synchronous
Motion；In whole process, lower link bar spring (217) is constantly in compressive state, both ensure that upper and lower core is in contact shape
State, while also ensure that core cover plate (213), core plate (215) assembly are brought into close contact with material scraping plate (210), ensure
The synchronization of three.In core cover plate (213), core plate (215) assembly and material scraping plate (210) upwards motion process,
Being held due to the lower core contiguous block (315) that central slide body (306) is installed on moving platen (107) to move, and type
The slotted eye in core backing plate (215) center forms bottom surface outer less than core slide body one~six, so, core plate (215) will
Promote lower core block one (300), lower core block two (301), lower core block three (302), lower core block four (303), lower core block
Five (304), lower core block six (305) are moved along the T-slot on central slide body (306), it is achieved thereby that internal thread Leave out thread
Action；
3) product material scraping plate ejects
After realizing that internal thread comes off, during upwards, spacing control small slide block (224) is released control block by spacing
(223) compressing, compressing small slide block spring (225) is moved into groove, the g1 points on spacing control small slide block (224) are crossed
After spacing releases the g2 points in control block (223), spacing control small slide block (224) will depart from spacing drag hook (231), meanwhile,
Core push pedal cover plate (222) will be by the obstruction at support block (108) grooving edge, it is impossible to continues up, so as to realize scraper push pedal
Component will continue to press on material scraping plate in the separation of core push pedal component, scraper push pedal component by material scraping plate release link (212)
(210) upwards, the de- material of product is realized, realizes the final demoulding of product；
4) closure of mould
After product takes out, mould closure, during closure, by the pulling of pulling back of injection machine pull bar, material scraping plate push pedal component, core push away
Board component pulls on material scraping plate release link (212), material scraping plate is coupled screw (211), lower link bar (218), lower link bar screw (216)
Material scraping plate (210), core push pedal cover plate (222), core push pedal (226) is driven to retract, spacing controlling organization is in material scraping plate push pedal
Realize and reset under the promotion of component, closed from the reset for realizing whole mould.
