Abstract
The utility model provides a kind of novel sectional variable diameter mold insert structure.A kind of novel sectional variable diameter mold insert structure, wherein, including mold core connector and several mold core connectors that can be detachably connected with the mold core connector, the mold core connector includes R sections of outer diameter, and R sections of outer diameter of outer diameter of each mold core connector is adapted with the internal diameter of the different grades of tubing of a certain specification respectively.The utility model replaces mold core without demoulding, only the mutual conversion of grade need to can be realized by replacing screw-type connection head at mouth mold, quickly, conveniently, and also it is time saving and energy saving.
Description
Technical field
The utility model relates to plastic conduit manufacturing technology fields, more particularly, to a kind of novel sectional variable diameter mould
Cored structure.
Background technique
PP-R(atactic copolymerized polypropene) pipe routine specification is essentially Φ 20-110, grade be divided into four grade 1.25MPa,
1.6MPa, 2.0MPa, 2.5MPa etc., the different grade of same format change is all needed the mold core in mold under normal production scenarios
Outer diameter R is changed to corresponding size, such as DN20: mold core R=16.5mm of PN1.6MPa mold core R=20mm, 2.0MPa.No
Ad eundem tubing is since wall thickness is different therefore corresponding various sizes of mold core, and most of producer is all one on the whole at present
Body formula mold core just needs demoulding to change the mold core when board replaces grade as depicted in figs. 1 and 2, usually changes set mold core heating and opens again
Machine adjusts wall thickness to finished product out to need or so 4 hours, and not only time-consuming but also labor intensive, existed simultaneously industrial accident risk.
Utility model content
The utility model in order to overcome at least one of the drawbacks of the prior art described above, provides a kind of novel sectional variable diameter
Mold insert structure.The utility model replaces mold core without demoulding, need to only be can be realized at mouth mold by replacing screw-type connection head
The mutual conversion of grade, quickly, conveniently, and also it is time saving and energy saving.
In order to solve the above technical problems, the technical solution adopted in the utility model is: a kind of novel sectional variable diameter mold core
Structure, wherein including mold core connector and several mold core connectors that can be detachably connected with the mold core connector, the mould
Core connector includes R sections of outer diameter, R sections of outer diameter of outer diameter of each mold core connector respectively with the different grades of pipe of a certain specification
The internal diameter of material is adapted.In this way, traditional integral type mold core is changed to segmented mold core, when tubing manufacture board replacement grade
There is no need to demouldings to change the mold core, and only needing to remove conversion at mouth mold can be real with respective outer diameters R sections of mold core connector
The now process, fast and easy；It, can be just normally opened without adjusting evenness of wall thickness and since mold core linkage section and mouth mold mold do not move
Machine, whole process can be completed in 5 minutes, and demoulding-is clear caused by mold core is needed replacing when improving conventional conversion pipe grade
A series of i.e. time-consuming labor intensives again such as the die-filling-heating-booting tune wall thickness of mould-mold changing core-exist simultaneously industrial accident risk
Mold changing process.
Further, the both ends of R sections of the outer diameter of the mold core connector are respectively equipped with linkage section and secondary segment, and secondary segment can
With mold core connector easy to disassemble, one end that the mold core connector is connect with the mold core connector is equipped with and the linkage section
The connecting groove of cooperation.The inner wall of the connecting groove is equipped with the first screw thread, the outer wall of the linkage section be equipped with it is described
First the second screw thread being threadedly engaged, the mold core connector are detachably connected with the mold core connector by screw thread rotation realization
It connects.
Compared with prior art, the utility model has the beneficial effects that
The segmented mold insert structure of the utility model, which only needs to change mold core connector (i.e. outer diameter R sections) and can be realized, quickly to be turned
Pipe grade is changed, the time only needs 5 minutes；Compared to traditional demoulding replacement mold core, heating, booting, wall thickness is adjusted to need time-consuming 4 hours
Situation, production efficiency are greatly enhanced.
The utility model is as improving the safety of production without demoulding therefore there is no industrial injury risk existing for disassembly mold
Property.
The utility model saves the expenses such as labour cost and the electricity charge loss in demoulding die-filling 4 hours, reduces tune wall
Scrap weight caused by thickness substantially increases plant produced efficiency and benefit.
Detailed description of the invention
Fig. 1 is tubing production mould runner schematic diagram.
Fig. 2 is traditional mold insert structure schematic diagram.
Fig. 3 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is further described below with reference to embodiment and reference examples.These embodiments are only to this reality
It is described with novel typical case, but the utility model is without being limited thereto.Test method used in following embodiments and reference examples for example without
Specified otherwise is conventional method, used raw material, reagent etc., and unless otherwise specified, being can be from the business such as regular market purchase
The raw materials and reagents that approach obtains.
As shown in figure 3, a kind of novel sectional variable diameter mold insert structure, wherein including mold core connector 1 and it is several can be with institute
The mold core connector 2 that mold core connector 1 is detachably connected is stated, the mold core connector 2 includes outer diameter R section 21, each mold core
The outer diameter of the outer diameter R section 21 of connector 2 is adapted with the internal diameter of the different grades of tubing of a certain specification respectively.In this way, by traditional
Integral type mold core be changed to segmented mold core, when tubing manufacture board replacement grade, there is no need to demouldings to change the mold core, and only need
Conversion is removed at mouth mold, and there is the mold core connector 2 of respective outer diameters R section 21 process, fast and easy can be realized；And by
Do not moved in mold core junction and mouth mold mold, without adjust evenness of wall thickness can normal boot-strap, whole process can be complete in 5 minutes
At needing replacing demoulding-caused by mold core when improving conventional conversion pipe grade, clear mould-mold changing core is-die-filling-heats up-open
A series of i.e. time-consuming labor intensives again such as machine tune wall thickness exist simultaneously the mold changing process of industrial accident risk.
As shown in figure 3, the both ends of the outer diameter R section 21 of the mold core connector 2 are respectively equipped with linkage section 22 and secondary segment 23,
Secondary segment 23 can be convenient disassembly mold core connector, and one end that the mold core connector 1 is connect with the mold core connector 2 is equipped with
With the connecting groove 11 of the linkage section 22 cooperation.The inner wall of the connecting groove 11 is equipped with the first screw thread, the linkage section
22 outer wall is equipped with the second screw thread being threadedly engaged with described first, and the mold core connector 1 and the mold core connector 2 are logical
Screw thread rotation realization is crossed to be detachably connected.
Obviously, the above embodiments of the present invention is used for the purpose of clearly demonstrating examples for clearly illustrating the present invention,
And it is not limitations of the embodiments of the present invention.For those of ordinary skill in the art, it is stated upper
It can also be made other variations or changes in different ways on the basis of bright.There is no need and unable to give all embodiments
