Abstract
The invention relates to the technical field of lower dies, and especially relates to a lower die for a plastic end cover. The lower die is used for producing plastic end covers. The lower die comprises a lower die block, a lower die cavity is arranged in the lower die block, the lower die block is uniformly provided with four guiding holes, push rods connected with an upper die are arranged in the four guiding holes respectively, one of the outer side surfaces of the lower die cavity is provided with a first semicircular groove, one of the inner side surfaces of the lower die block is provided with a second semicircular groove, the second semicircular groove and the first semicircular groove are spliced to form a whole circular groove, and a guide column is arranged in the whole circular groove formed by the second semicircular groove and the first semicircular groove. The lower die for the plastic end cover allows the lower die cavity to be easily guided out of the lower die block through the guide column arranged between the lower die block and the lower die cavity.
Description
Technical field
The present invention relates to the technical field of counterdie, especially a kind of plastic end cover counterdie.
Background technology
Mold for Plastics is the mould for plastic shaping, comprise upper die and lower die, existing plastics counterdie generally only including lower module, being placed in the lower mode cavity in lower module and the push rod for connecting upper and lower mould, but the mould of this structure is difficult to lower mode cavity to take out from lower module, by loop wheel machine, lower mode cavity can only be hung out, the complexity operated very.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the problem proposed in above-mentioned background technology, the invention provides a kind of plastic end cover counterdie, by the guide pillar arranged between lower module and lower mode cavity, lower mode cavity can be derived very easily from lower module.
The technical solution adopted for the present invention to solve the technical problems is: a kind of plastic end cover counterdie, for the production of manufacture plastic end cover, comprise lower module, lower mode cavity is provided with in lower module, lower module evenly offers four pilot holes, the push rod connecting patrix is respectively installed in four pilot holes, one lateral surface of lower mode cavity offers the first semi-circular groove, one medial surface of lower module offers the second semi-circular groove piecing together a full circle groove with the first semi-circular groove, in the full circle groove that the first semi-circular groove and the second semi-circular groove piece together, guide pillar is installed.
Further restriction: the Cooling Holes side of lower module offering multiple installation cooling water pipeline.
Further restriction: the lateral surface of lower module offers anti-swollen groove.
Further restriction: the lateral surface of lower module offers the screw hole for installing suspension ring.
Beneficial effect of the present invention: this plastic end cover counterdie, by the guide pillar arranged between lower module and lower mode cavity, can derive lower mode cavity very easily from lower module; The Cooling Holes that lower module is offered, conveniently can install cooling water pipeline, and then is convenient to carry out suitable cooling to mould; The anti-swollen groove that lower module lateral surface is offered, can prevent lower module spalling, extends the service life of lower module; Screw hole on lower module lateral surface, can be used for installing suspension ring, to be hung out from lower module by lower mode cavity.

Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
Plastic end cover counterdie as shown in Figure 1, Figure 2 and Figure 3, for the production of manufacture plastic end cover, comprise lower module 1, lower mode cavity 2 is provided with in lower module 1, lower module 1 evenly offers four pilot holes 3, the push rod 4 connecting patrix is respectively installed in four pilot holes 3, one lateral surface of lower mode cavity 2 offers the first semi-circular groove 5, one medial surface of lower module 1 offers the second semi-circular groove 6 piecing together a full circle groove with the first semi-circular groove 5, in the full circle groove 7 that the first semi-circular groove 5 and the second semi-circular groove 6 piece together, guide pillar 8 is installed.The side of wherein lower module 1 offers the Cooling Holes 9 of multiple installation cooling water pipeline.The lateral surface of lower module 1 offers anti-swollen groove 10.The lateral surface of lower module 1 offers the screw hole 11 for installing suspension ring.
This plastic end cover counterdie, by the guide pillar 8 arranged between lower module 1 and lower mode cavity 2, can derive lower mode cavity 20 points easily from lower module 1; The Cooling Holes 9 that lower module 1 is offered, conveniently can install cooling water pipeline, and then is convenient to carry out suitable cooling to mould; The anti-swollen groove 10 that lower module 1 lateral surface is offered, can prevent lower module 1 spalling, extend the service life of lower module 1; Screw hole 11 on lower module 1 lateral surface, can be used for installing suspension ring, to be hung out from lower module 1 by lower mode cavity 2.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
