Under new the effect of can be generated and the purpose that can reach, all should still it fall in the technology contents institute energy disclosed in the utility model
In the range of covering.Meanwhile cited such as " on ", " under ", "left", "right", " centre " and " one " term in this specification,
It is merely convenient to narration to understand, and is not used to limit the enforceable scope of the utility model, its relativeness is altered or modified,
In the case where changing technology contents without essence, when being also considered as the enforceable category of the utility model.
As shown in figure 1, the utility model provides a kind of core fixed mechanism, including the pressing plate 1 on die ontology,
Pressing plate 1 is provided with dismounting through hole 11, dismounts in through hole 11 and removably installs limited location plug 2, spacing plug 2 can give core 3
Apply fixation power, the diameter of dismounting through hole 11 is more than the diameter of core 3, plug through hole 21, plug are provided with spacing plug 2
Through hole 21 is used to wear the cooling water pipe 4 being connected with core 3.The operation principle of core fixed mechanism is in the utility model:
Pressing plate 1 applies fixation power by spacing plug 2 to core 3, and core 3 is fixed on die ontology, meanwhile, work as needs
When changing some core 3, first corresponding spacing plug 2 is disassembled from dismounting through hole 11, due to the utility model
The diameter of middle dismounting through hole 11 is more than the diameter of core 3, can directly by the dismounting through hole 11 by corresponding core 3 from mould sheet
Disassemble and take out on body, then again by new core 3 through the dismounting through hole 11 and on die ontology, again finally
The spacing plug 2 pulled down is fitted into dismounting through hole 11, to apply fixation power to the core 3 after replacing;By using this
Core fixed mechanism in utility model, when changing core 3, without pressing plate 1 of dismantling again, more changing jobs for core 3 is facilitated, is subtracted
The workload of worker is lacked and has repaired a die the time.
Meanwhile as shown in figure 1, the utility model also provides a kind of mould, including die ontology, on die ontology
Core 3 and the cooling water pipe 4 that is connected with core 3, and the mould also includes above-mentioned core fixed mechanism.This practicality is new
Mould in type, based on its core fixed mechanism, facilitate the replacing of core 3.
As shown in figure 1, spacing plug 2 is threadedly coupled with dismounting through hole 11 in the present embodiment, i.e., it is spacing stifled in the present embodiment
First 2 lateral wall is provided with external screw thread, and the side wall of dismounting through hole 11 is provided with the internal thread being engaged with external screw thread, to realize limit
The detachable installation of position plug 2.Meanwhile as shown in figure 1, spacing plug 2 is provided with spanner auxiliary section 22, the spanner auxiliary section 22
For being engaged with spanner, facilitate the use spanner and spacing plug 2 is fitted into dismounting through hole 11 or torn open from dismounting through hole 11
Unload down.The spanner auxiliary section 22 of spacing plug 2 specifically uses interior hexagonal fit structure in the present embodiment, to ensure that the spanner is matched somebody with somebody
Conjunction portion 22 can be engaged with inner hexagon spanner.In addition, the spanner auxiliary section 22 of spacing plug 2 is located at plug through hole in the present embodiment
In 21 side wall.
As shown in figure 1, core fixed mechanism in the present embodiment, in addition to the insert 6 on the cover half of die ontology,
Core mounting hole 61 is provided with insert 6, above-mentioned core 3 is embedded in core mounting hole 61, and spacing plug 2 can apply to core 3
Fixation power forward, insert 6 can apply fixation power backward to core 3, with reference to core mounting hole 61 to core 3
Fixation, so as to realize the fixation to core 3.
As shown in figure 1, core fixed mechanism also includes core extension device 5, the rear end of the core extension device 5 in the present embodiment
Leant with spacing plug 2, front end and core 3 lean, so, in the present embodiment spacing plug 2 by core extension device 5 with
Core 3 leans and applies fixation power forward to core 3.
As shown in figure 1, cooling water pipe 4 includes water inlet pipe 41 and return pipe 42 in the present embodiment;It is provided with above-mentioned core 3 cold
But chamber 31, the delivery port of water inlet pipe 41 communicates with cooling chamber 31, and the water inlet of return pipe 42 communicates with cooling chamber 31.Using
When, cooling water flows into cooling chamber 31 by water inlet pipe 41, to realize the cooling to core 3, and lifts the local matter of die-cast product
Amount;Then, the cooling water in cooling chamber 31 is flowed out by return pipe 42 again, to realize continuous stream of the cooling water in cooling chamber 31
It is dynamic.
Meanwhile as shown in figure 1, return pipe 42 is set in the outside of water inlet pipe 41 in the present embodiment;And return pipe 42 is with entering
There is the backwater path 421 communicated with cooling chamber 31 between water pipe 41.After cooling water enters cooling chamber 31 by water inlet pipe 41, then
Flowed out by the backwater path 421 in return pipe 42, so as to realize the continuous flowing of cooling water.In the present embodiment return pipe 42 with
Water inlet pipe 41 uses such a fit form, has both realized the continuous flowing of cooling water, and its take the inner space of core 3 compared with
It is small so that the diameter of core 3 can keep less scope in the present embodiment.
As shown in figure 1, being provided with water pipe mounting hole in the present embodiment in core 3, above-mentioned return pipe 42 inserts water pipe installation
Kong Zhong, and two the first sealing rings 7 are provided with the lateral wall of return pipe 42, return pipe 42 by two the first sealing rings 7 with
The side wall tight fit of water pipe mounting hole, and realize that both sealings coordinate.Meanwhile covered in the present embodiment on the lateral wall of core 3
Provided with the second sealing ring 8, core 3 is realized between the two by the side wall tight fit of second sealing ring 8 and core mounting hole 61
Sealing coordinate.The first sealing ring 7 and the second sealing ring 8 use O-ring seal in the present embodiment.

Connected with water inlet pipe 41 and return pipe 42.
Dismounting through hole 11 on the present embodiment center platen 1 have it is multiple, it is each dismount through hole 11 be mounted on it is above-mentioned spacing stifled
First 2.So, the present embodiment center platen 1 is applied solid to multiple cores 3 simultaneously by the spacing plug 2 in multiple dismounting through holes 11
It is set for firmly.And in the present embodiment, when changing some core 3, it only need to first pull out cooling water pipe 4 and water on the core 3
Pipe joint, inner hexagon spanner is recycled to twist off the spacing plug 2 to be leant with the core 3, core extension device 5 corresponding to taking-up,
Directly core 3 can be changed by the dismounting through hole 11, without pressing plate 1 of dismantling;And then without by other cooling waters
Pipe 4 and water pipe head are pulled out from corresponding core 3, reduce workload, and avoid damaging the first sealing in other cores 3
Circle 7.
Multiple spacing plugs 2 are installed as shown in figure 1, each being dismounted in the present embodiment in through hole 11, to strengthen to core 3
Fixation.Meanwhile each dismounted in the present embodiment in through hole 11 and be particularly fitted with two spacing plugs 2.In the present embodiment
The internal thread specification for dismounting through hole 11 is M20 × 1.5.
Mould is for the die casting for the cylinder body for processing automobile in the present embodiment.
The utility model is improved for the structure of pressing plate 1, is realized in the case where not removing pressing plate 1 to core
3 carry out quick-replaceable, reduce the workload for the worker that repairs a die, shorten the time that repairs a die.
In summary, the utility model effectively overcomes various shortcoming of the prior art and has high industrial exploitation value
Value.
Above-described embodiment only illustrative principle of the present utility model and its effect are new not for this practicality is limited
