[0002] In the prior art, application number CN202311317084.7 discloses a co-extrusion die for an artificial water-washing stone extruder with free foaming in the core, comprising a mouth template, a manifold, a bracket plate and a machine neck. The center positions of the mouth template, the manifold bracket plate and the machine neck are all provided with a center hole. A mounting block is installed in the center hole of the bracket plate. A main material flow channel is provided in the center of the mounting block. A diverter is provided in the main material flow channel. The diverter is fixed to the center position of the main material flow channel through a connecting block. One end of the diverter is connected to a flow channel pipe, which is placed in the center hole of the mouth template and the manifold. An L-shaped co-extrusion flow channel is provided on the top of the diverter, the connecting block and the bracket plate. The present invention adopts a mold separation distance between the main material and the co-extrusion material so that the core unfoamed plastic can have enough space for free foaming after being released from the mold, thereby ensuring and improving the foaming ratio of the core plastic; and for the easily worn flow channel cavity, a replaceable modular design is adopted to improve the service life and reduce the maintenance cost.

[0003] In actual production, when the co-extrusion die of the artificial water-washing stone extruder is shut down for maintenance, it is not convenient to adjust and disassemble the die plate, manifold, bracket plate and machine neck because their positions are relatively fixed. As a result, the residual material in the co-extrusion die cannot be cleaned in time, affecting subsequent production and processing. Utility Model Content

[0026] This embodiment discloses an extrusion die for artificial water-washing stone, comprising a machine neck 1, a support plate 2, a manifold 3, a die plate 4, and a guide column 5 sequentially passing through the machine neck 1, the support plate 2, the manifold 3, and the die plate 4; wherein the support plate 2 is coaxially arranged on one end side of the machine neck 1, and the manifold 3 and the die plate 4 are coaxially arranged on the other end side of the support plate 2; a main material flow channel 101 is designed on the end side of the machine neck 1; a co-extrusion flow channel opening 201 is opened on the top of the support plate 2; when in use, the machine neck 1 is fixedly mounted on the extruder.

[0027] A diverter 9 is installed in the main material flow channel 101, and a detachable and washable flow channel pipe 10 connected to the diverter 9 is installed in the center of the manifold 3 and the mouth template 4 for detachable connection; specifically, it can be a threaded sleeve connection.

[0028] Specifically, this embodiment is an improvement on the co-extrusion die of an artificial water-washing stone extruder with free-foaming core, as disclosed in patent application number CN202311317084.7. The neck 1 is coaxially mounted on one end of the support plate 2, and the manifold 3 and the die plate 4 are coaxially mounted on the other end of the support plate 2.

[0029] like Figure 1 As shown, in this embodiment, the machine neck 1, the support plate 2, the manifold 3, and the die plate 4 are tightened and adjusted by the deflection adjustment nut 7 installed on the guide column 5. Figure 3As shown, specifically, a through hole 103 adapted to the guide column 5 is axially opened on the machine neck 1, the bracket plate 2, the manifold plate 3, and the mouth template 4 respectively.

[0030] In this embodiment, a reserved hole is provided on the bracket plate 2 for installation on the machine neck 1 .

[0031] The deflection adjustment nut 7 pushes the mouth template 4 to prevent gaps from appearing between the mouth template 4, the manifold 3, and the bracket plate 2 in the horizontal direction, thereby achieving close fitting and coaxial sealing communication between the two.

[0032] During specific implementation, assembly reserved holes 301 for installation on the machine neck 1 are symmetrically opened on the end faces of the convergence plate 3 and the mouth template 4; reserved through holes corresponding to each of the assembly reserved holes 301 are also opened at the end of the bracket plate 2, and threaded holes are opened on the machine neck 1 to facilitate the fixed connection of the convergence plate 3 and the mouth template 4 by bolts.

[0033] In this embodiment, a bracket 8 is installed under the machine neck 1, the convergence plate 3, and the mouth template 4; a deflection telescopic cylinder 6 for adjusting the deflection is installed on the outer side walls of the convergence plate 3 and the mouth template 4 respectively; specifically, the top of the bracket 8 is an arc-shaped plate adapted to the bottom outer wall of the machine neck 1, the convergence plate 3, and the mouth template 4; wherein the bracket 8 is used to bear the gravity of the template itself after the template locking screws are removed to avoid uncontrolled misalignment between the templates.

[0034] During use, when the deflection and telescopic cylinder 6 does not need to be telescoped and deflected for adjustment, the bracket 8 is used to support the manifold 3 and the bottom of the orifice template 4 .

[0035] In this embodiment, Figure 1-3 As shown, two hinged lugs 102 are vertically mounted on the outer sidewalls of the manifold 3 and the die plate 4, respectively. A hinge shaft is mounted between the two hinged lugs 102. The telescopic end of the deflection and telescopic cylinder 6 is adapted to fit onto the hinge shaft via an upper hinge seat 602. The lower end of the deflection and telescopic cylinder 6 is hingedly connected to a fixed seat via a lower hinge seat 601.

[0036] Before cleaning, first, the detachable flow channel pipe 10 is removed from the diverter 9.

[0037] The deflection telescopic cylinder 6 is used to adjust the deflection of the manifold plate 3 and the mouth template 4 respectively, specifically with the guide column 5 as the rotation axis, so as to facilitate the misalignment of the bracket plate 2, the manifold plate 3, and the mouth template 4 in pairs, so as to facilitate the cleaning of debris or impurities inside them; thereby, when the machine is shut down, the debris inside can be cleaned out in time to prevent clogging inside and avoid affecting subsequent production and processing.

[0038] In this embodiment, Figure 5 As shown, the manifold 3 and the die plate 4 can be deflected and adjusted simultaneously by the same deflection telescopic cylinder 6 .

[0039] The above embodiments are only descriptions of the preferred methods of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
