Embodiment
Below, substantive distinguishing features of the present utility model and advantage are further described with reference to example, but this practicality is new
Type is not limited to listed embodiment.
As shown in Figures 1 to 5, a kind of secondary ejecting mechanism of injection mould of the present embodiment includes straight head part 1, thimble 2, directly
Footstock 3, spring 4, limit base 5, big mold insert 6 and ejector retainner plate 7, described straight one end of head part 1 are plugged in big mold insert 6, and the other end is inserted
It is located in straight footstock 3.The straight footstock 3 includes limiting section 31 and resettlement section 32, and limiting section 31 is arranged on straight footstock bottom, described
Spring 4 is arranged in resettlement section 32.In the present embodiment, the limiting section is the annular protrusion for protruding from straight footstock outer surface.Institute
Stating limit base 5 includes accommodating chamber 51, and the limiting section 31 is arranged in accommodating chamber 51 so that and straight footstock can move up and down, when
When straight footstock is moved upward to limiting section 31 and contacted with the confined planes above limit base, straight footstock is by limitation movement.The thimble 2
One end is arranged on ejector retainner plate 7, and the other end is located in straight head part 1, and the ejector retainner plate 7 is arranged on the straight top of footstock 3.Above-mentioned skill
In art scheme, when product ejects after die sinking, straight footstock and ejector retainner plate move upwards so that straight head part 1 and thimble 2 together push up
