Description
Technical field
This utility model relates to plastic tray injection mold, particularly relates to plastic tray injection mold longer wide-edge and changes core-pulling mechanism.
Background technology
nullPlastic pallet typically uses rectangular structure，The a length of 1200mm on its long limit，The a length of 1000mm of broadside，And in order to improve the structural strength of plastic pallet，People can have the steel pipe hole on long limit and the steel pipe hole of broadside in pallet，Owing to the length in the steel pipe hole on long limit and the steel pipe hole of broadside is the longest，Therefore steel pipe hole can be extracted out respectively by the injection mold of plastic pallet from the both sides of mould，So can shorten the length loosed core，And the die cavity having plastic tray injection mold is typically to arrange the long limit of pallet towards the left and right sides，Broadside is arranged towards upper and lower both sides，Upper at core、Under、Left、Side oil pumping cylinder it is respectively provided with on right side wall，So cause mould higher position to be arranged on could install on the downside of side oil pumping cylinder，Thus increase mould volume，Needs use more large-tonnage injection machine，Improve the development cost of injection machine and mould.
Summary of the invention
The purpose of this utility model is the shortcoming in order to overcome prior art to exist, a kind of plastic pallet that converts is provided to be positioned at the position of length and width in mould cavity, using the injection machine of less tonnage, the plastic tray injection mold longer wide-edge of the development cost reducing injection machine and mould changes core-pulling mechanism.
nullThis utility model plastic tray injection mold longer wide-edge changes the technical scheme of core-pulling mechanism: include compound plate and lower compound plate，Backing plate and runner plate are set under upper compound plate，Under backing plate, die cavity is set，Under die cavity, cavity block is set，On lower compound plate, mould foot is set，On lower compound plate between mould foot, ejector retainner plate is set、Lower ejector retainner plate and thimble，On mould foot, core is set，Core insert is set on core，The plastic pallet of injection mo(u)lding is had between cavity block and core insert，Plastic pallet has long limit and broadside，Plastic pallet is positioned at side, long limit and has steel pipe hole, long limit，Plastic pallet is positioned at broadside side and has broadside steel pipe hole，It is characterized in that: the upside of described core arranges long side core-pulling slide block，Long side core-pulling slide block connects long limit steel pipe and looses core，Long side core-pulling slide block drives through long limit oil cylinder，Broadside side action sliders before the front side of core is arranged，Before front broadside side action sliders connects, broadside steel pipe is loosed core，Front broadside side action sliders premenstrual broadside oil cylinder drives，The rear side of core arranges rear broadside side action sliders，After rear broadside side action sliders connects, broadside steel pipe is loosed core，Rear broadside side action sliders through after broadside oil cylinder drive.
nullThe utility model discloses a kind of plastic tray injection mold longer wide-edge and change core-pulling mechanism，It is positioned at the position of length and width in injection mold die cavity by conversion plastic pallet，The long limit of plastic pallet that will be original is positioned at both sides before and after mould，Broadside is positioned at the both sides up and down of mould，And change now plastic pallet into and be positioned at long limit and be positioned at the both sides up and down of mould，Broadside is positioned at both sides before and after mould，The width so making whole secondary mould increases，Reduced height，Loose core additionally, due to long limit steel pipe consistent with the width edge length of plastic pallet for 1000mm，Broadside steel pipe is loosed core and is allocated as before and after two，Before、The loose core half of the length for the long limit of plastic pallet of rear broadside steel pipe is 600mm，Long limit steel pipe is loosed core and only extracts out from the upside of mould，Rather than loose core respectively from the both sides up and down of mould，Although adding the height of long limit oil cylinder，But reduce the height of mould，Mould volume is made to reduce，The injection machine of less tonnage can be used，Thus reduce the development cost of injection machine and mould.

Detailed description of the invention
nullThis utility model relates to a kind of plastic tray injection mold longer wide-edge and changes core-pulling mechanism，As shown in Fig. 1 Fig. 2，Including upper compound plate 1 and lower compound plate 2，Backing plate 3 and runner plate are set under upper compound plate，Die cavity 4 is set under backing plate，Under die cavity, cavity block is set，On lower compound plate, mould foot 5 is set，On lower compound plate between mould foot, ejector retainner plate 6 is set、Lower ejector retainner plate 7 and thimble，Core 8 is set on mould foot，Core insert 9 is set on core，The plastic pallet of injection mo(u)lding is had between cavity block and core insert，Plastic pallet has long limit and broadside，Plastic pallet is positioned at side, long limit and has steel pipe hole, long limit，Plastic pallet is positioned at broadside side and has broadside steel pipe hole，It is characterized in that: the upside of described core 8 arranges long side core-pulling slide block 10，Long side core-pulling slide block connects long limit steel pipe and looses core 11，Long side core-pulling slide block drives through long limit oil cylinder 12，Broadside side action sliders 13 before the front side of core is arranged，Before front broadside side action sliders connects, broadside steel pipe looses core 14，Front broadside side action sliders premenstrual broadside oil cylinder 15 drives，The rear side of core arranges rear broadside side action sliders 16，After rear broadside side action sliders connects, broadside steel pipe looses core 17，Rear broadside side action sliders through after broadside oil cylinder 18 drive.nullIt is positioned at the position of length and width in injection mold die cavity by conversion plastic pallet，The long limit of plastic pallet that will be original is positioned at both sides before and after mould，Broadside is positioned at the both sides up and down of mould，And change now plastic pallet into and be positioned at long limit and be positioned at the both sides up and down of mould，Broadside is positioned at both sides before and after mould，The width so making whole secondary mould increases，Reduced height，Loose core additionally, due to long limit steel pipe 11 consistent with the width edge length of plastic pallet for 1000mm，Broadside steel pipe is loosed core and is allocated as before and after two，Before、Rear broadside steel pipe looses core 14、The half of the length that 16 is the long limit of plastic pallet is 600mm，Long limit steel pipe is loosed core 11 only from the extraction of the upside of mould，Rather than loose core respectively from the both sides up and down of mould，Although adding the height of long limit oil cylinder 12，But reduce the height of mould，Mould volume is made to reduce，The injection machine of less tonnage can be used，Thus reduce the development cost of injection machine and mould.
