Description
Technical field
The present invention relates to mould applications, specifically a kind of easy-to-mount multilayer die mechanism.
Background technique
In tube extrusion production process, mold is frequently necessary to dismount, and traditional assembly and disassembly methods are will be whole after entire heating
Body is split out, then reheats the remaining sizing material in cleaning runner one by one, and not only working strength is very big in this way, but also is easy to
Clearing up during remaining sizing material reheats causes die body to deform, and influence mold reassembles precision.
Therefore, how to solve the above problems, become urgent problem to be solved.
Summary of the invention
The present invention is mentioned for the dismounting cleaning mold problem is frequently necessary in multi-layer tubes extrusion die production process
The multi-layer flow channels of mold are existed in the case where not having to mold overall pulling down for a kind of easy-to-mount multilayer die mechanism
Assembly lower runner of heated condition splits out cleaning one by one, not only convenient and efficient in this way, but also runner is expected clearly one by one, and die body is not having
Remaining sizing material is cleared up in the state of cooling completely, does not need to heat again, guarantees that die body is indeformable, finally guarantees that mold reassembles
Precision.
To achieve the above object, the technical scheme is that
A kind of easy-to-mount multilayer die mechanism is arranged in die head including the die head ontology being fixed on mould bases
Multi-layer flow channels, the arrival end that each layer of multi-layer flow channels are equipped with one section of internal screw thread, and side corresponding with internal screw thread is equipped with thread rack, spiral shell
Line bracket is multi-diameter shaft, and each layer is equipped with the external screw thread matched with internal screw thread.It is connected through a screw thread thread rack and stream
Road screws, and runner can be pulled out out of die head ontology.It is dismounted relative to traditional heating, it is simple and convenient, avoid mold from adding
Caused die body deformation after heat.
Further multi-layer flow channels entrance side is equipped with the briquetting for pushing down runner end face, which individually pushes down
The end face in each laminar flow road.It can not be split out, be conducive to orderly by the thread rack screwed by the runner that briquetting is pushed down
Each laminar flow road is split out, the mutual damage between runner is avoided.
Further thread rack, which is equipped with, screws out structure.Screw out structure to dismount runner it is more laborsaving, conveniently.
Further screwing out structure includes screw rod, nut, flange, guiding axis, and guiding axis is fixed on die head ontology, guiding axis
Other end mounting flange, flange run through screw rod, and screw rod is fixed with thread rack, and nut and screw rod are fitted to screw rod upper flange
Outside.The back-out mechanism rapid operation of screw structure, it is easy to accomplish, and precision is high, can be good at protecting runner.
Further nut is equipped with handle.It is convenient to use that handle is set.
The present invention has following technological merit compared with prior art:
1, thread rack and runner screw, and by operating screw body, easily draw in every laminar flow road out of die head ontology
Out；2, do not having to runner be torn the multi-layer flow channels of mold one by one in the case where assembling heated condition open under the shape of mold overall pulling down
It clears up out, it is not only convenient and efficient in this way, and also runner is expected clearly one by one, it is ensured that die body is clear in the state of no completely cooling
Remaining sizing material is managed, does not need to heat again, guarantees that die body is indeformable, to guarantee the precision that mold reassembles.

Specific embodiment
The present invention is described in further detail below in conjunction with the embodiment in attached drawing.
As shown in Fig. 1 to 5, easy-to-mount multilayer die mechanism of the invention, including the die head sheet being fixed on mould bases
The multi-layer flow channels 9 in die head are arranged in body 6, and the arrival end that 9 each layers of multi-layer flow channels is equipped with one section of internal screw thread 9a, with internal screw thread
The corresponding side 9a is equipped with thread rack 4, and thread rack 4 is multi-diameter shaft, and each layer is equipped with the outer spiral shell matched with internal screw thread 9a
Line 4a.
As shown in Fig. 1/5,9 entrance side of multi-layer flow channels is equipped with the briquetting 5 for pushing down 9 end face of runner, the adjustable section of briquetting 5
It sets, individually pushes down the end face in each laminar flow road 9.
As shown in Fig. 1/2/5, thread rack 4, which is equipped with, screws out structure A.
As shown in Fig. 1/4, screwing out structure A includes screw rod 1, nut 2, flange 8, guiding axis 3, and guiding axis 3 is fixed on die head
On ontology 6,3 other end mounting flange 8 of guiding axis, flange 8 runs through screw rod 1, and screw rod 1 and thread rack 4 are fixed, nut 2 and silk
Bar 1 is fitted to 1 upper flange of screw rod, 8 outside.Nut 2 is equipped with handle 7.
In operating process, die head is integrally attached on mould bases, and external heating coil is not removed, and continues the temperature for being heated to setting
Degree guarantees in the remaining sizing material processing molten condition in mould, by the external screw thread of thread rack 4 and corresponding runner in die head itself
Internal screw thread on 9 is screwed on, such as Fig. 3；Then artificial rotating handle 7, turns nut 2, by screw rod 1, briquetting 5, corresponding rotation
The runner connected is pulled out from die body, such as Fig. 5.
After internal layer runner 9 is pulled out out of die body, remaining sizing material cleaning in the runner that runner temperature does not descend general who has surrendered to have been pulled out is taken advantage of
Completely；Then the position for adjusting briquetting 5, pushes down the end face of corresponding runner, will be under the runner in thread rack 4 and die head ontology 6
Screw thread on one runner is screwed on, and successively remaining runner is pulled out and cleared up, and all runners have been cleared up, and entire die head is dismounted
Whole assembly again after cleaning.
