This pushing block chamber comprises restriction rib motion chamber and pushes away platform motion chamber, this restriction rib motion chamber pushes away platform motion chamber with this and is connected, this pushes away platform motion chamber and is positioned at this below, restriction rib motion chamber, this pushes away platform and is arranged in this and pushes away platform motion chamber, this restriction rib is arranged in this and pushes away platform motion chamber, the height of this restriction rib is less than this and pushes away the height in platform motion chamber, this pushes away below, platform motion chamber and is provided with restriction platform, this restriction rib can push away in platform motion chamber and pumps at this, and this restriction platform limits the downward range distance of this restriction rib, thereby further limit the downward range distance of this activity pushing block.
On the bottom surface of this fixing briquetting and on the end face of this activity pushing block, be respectively arranged with spring cavity, the two ends up and down of this spring are placed in respectively this spring cavity, can make more stable being arranged between this fixing briquetting and this activity pushing block of this spring by the structural design of this spring cavity.
In concrete enforcement, this fixing briquetting comprises top board and base frame, forms a hierarchic structure by this top board and this base frame, and hierarchic structure can make more stable being arranged in this briquetting chamber of this fixing briquetting.
In concrete enforcement, pin runs through from bottom to top and is arranged in this rear mold and this pushing tow unit.
The beneficial effects of the utility model are: the utility model is in specific works, in mold-closing injection, this rear mold is pushed this activity pushing block by inserts, make the playback that moves upward of this activity pushing block, thereby realize the injection moulding of product, at this inserts surrounding injection moulding plastic, in the time of die sinking, this fixing briquetting promotes this activity pushing block by this spring and moves downward, further, under this activity pushing block, push away this inserts, make it to this rear mold direction motion, thereby realize the not sticky front mould of product, the not de-flower of product, product easily takes out, mould high safety, simultaneously because product normally returns rear mold, robotic arm picking, can be mass.
