[0002] The forming mold for co-extrusion floors is a key tool for manufacturing co-extrusion floors. It involves a complex process of combining different materials through a co-extrusion process to form floors. The materials are conveyed to the feed inlet of the mold through a conveying device and enter the mold cavity. These materials are combined and extruded inside the mold to finally form co-extrusion floors with the properties of wood and plastic.

[0003] In the prior art, the Chinese utility model patent with the patent number CN207808423U discloses an extrusion mold for producing plastic co-extrusion floors, which includes a mold body. The mold body includes a die body plate, a transition plate, a support plate, a manifold plate, an orifice plate, a cooling water jacket, and a co-extrusion plate. The die body plate, the transition plate, and the support plate are internally provided with extrusion channels.

[0004] In the above prior art, although the temperature regulation performance of the entire mold is greatly improved, and the production efficiency and quality are greatly improved, however, the heat of the heating device located at the extrusion head part is mostly low. If the degree of material condensation is large, or the material is not completely melted, or there are impurities, blockage will occur during the co-extrusion process, resulting in affecting the overall extrusion efficiency of the extruder. Content of the Utility Model

[0005] The utility model provides a forming mold for square-hole co-extrusion floors to solve the technical problem that the heat of the heating device located at the extrusion head part is mostly low. If the degree of material condensation is large or the material is not completely melted, blockage will occur during the co-extrusion process, resulting in affecting the overall extrusion efficiency of the extruder.

Detailed implementation manners

[0024] In order to enable the personnel in the technical field to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0025] Refer to Figures 1-5 , a forming die for square hole co-extruded floor, including a box body 1. A flow equalizing plate 16 is arranged in the middle of the box body 1. The flow equalizing plate 16, also known as a flow distribution plate, is a fluid mechanical equipment for fluid kinetic energy conversion, which prevents the material from solidifying here, ensures the fluidity of the material, and at the same time increases the speed of the material flowing out of the flow equalizing plate 16, which is beneficial to injection co-extrusion molding. The flow equalizing plate 16 divides the inner cavity of the box body 1 into a feed bin 15 and a discharge bin 17. One end of the feed bin 15 is communicated with a feed pipe 2. A hollow plate 18 is fixedly installed on one side of the discharge bin 17 close to the flow equalizing plate 16, and a square column 19 is fixedly installed on one side of the hollow plate 18.

[0026] Refer to Figures 1-3 , the top of the feed bin 15 is assembled with a top plate 3. Mounting holes 14 are opened inside the top plate 3, and a fixing plate 4 is fixedly installed on the lower surface of the top plate 3. A filter plate 5 is fixedly installed inside the fixing plate 4. The filter plate 5 is used to filter incompletely melted material particles and impurity particles.

[0027] Refer to Figure 2, a side plate 6 is fixedly installed on the outer side surface of the fixed plate 4. The side plate 6 is arranged in a bucket shape, and a first heating mesh 7 is fixedly installed on the outer side of the side plate 6. The first heating mesh 7 is arranged obliquely. A second heating mesh 8 is fixedly connected between the first heating mesh 7 and the filter plate 5. The first heating mesh 7 and the second heating mesh 8 are used to heat the unmelted material particles, and after heating, they flow out from the mesh holes. The impurity particles in the material will remain on the first heating mesh 7 and the second heating mesh 8 and can be taken out after the work is completed.

[0028] Reference Figure 3 , an air valve 9 is arranged on the top of the top plate 3. The air valve 9 can be connected to a suction device. When installing the top plate 3 and the fixed plate 4, the air inside can be discharged to improve the product quality during discharging.

[0029] Reference Figure 3 , vertical rods 12 penetrate the top plate 3 symmetrically on the surface. At the same time, the vertical rods 12 penetrate the fixed plate 4. The vertical rods 12 are in sliding fit with the top plate 3 and the fixed plate 4. A scraper 10 that slides on the surface of the filter plate 5 is fixedly installed at the lower end of the vertical rods 12, which is used to scrape the blockages on the filter plate 5 to prevent the filter plate 5 from being blocked and affecting the work. The tops of the two vertical rods 12 are fixedly connected with a pressing plate 11. A spring 13 that is sleeved on the surface of the vertical rods 12 is connected between the pressing plate 11 and the top plate 3. When in use, press the pressing plate 11 to make the vertical rods 12 drive the scraper 10 to move downward to scrape the sundries on the surface of the filter plate 5. The spring 13 is used for the reset of the scraper 10.

[0030] Reference Figure 1 and Figure 6 , a spray box 20 is fixedly installed on one side of the top end of the box body 1. A water collecting tank 21 is fixedly installed on the top of the spray box 20. A water inlet pipe 22 is fixedly installed on the top of the water collecting tank 21. A first spray hole 23 is arranged at the bottom of the spray box 20, which is used for spraying and cooling the upper surface of the co-extruded plate.

[0031] Reference Figure 1 , a collecting box 24 for collecting spray water is arranged on the outside of the box body 1. A spray column 25 fixedly installed on the upper surface of the collecting box is arranged on one side of the discharge bin 17. A second spray hole 27 is opened at the top of the spray column 25, which is used for spraying and cooling the lower surface of the co-extruded plate. And a water passing conduit 26 is communicated on one side of the spray column 25, which can cool the upper and lower surfaces of the just-formed plate at the same time, accelerating the forming speed, which is better than directly immersing the plate in water for cooling. During the immersion process of the plate, water will penetrate into the interior of the plate comprehensively and deeply. Since the cell walls of the plate are full of water and reach a saturated state, the plate will undergo a wet expansion phenomenon, that is, the volume expands, and the wet expansion may cause the wooden board to burst.

[0032] Reference Figure 1, a conveying roller 28 is arranged on one side of the spray column 25 for conveying the plate, preventing the plate from being incompletely formed and not being conveyed. The extruded plate is prone to deformation under force.

[0033] Further, during use, the material enters from the feed pipe 2, is evenly distributed by the flow equalizing plate 16 and then discharged from the hollow plate 18, and is shaped by the fastening square column 19 to form a square plate. Subsequently, it is sprayed through the first spray holes 23 and the second spray holes 27 to accelerate the forming, and finally conveyed out by the conveying roller 28. The filter plate 5 and the top plate 3 are fixedly installed in the feed bin 15. The filter plate 5 is used to filter incompletely melted material particles and impurity particles. To prevent the filter plate 5 from being blocked during co-extrusion, the push plate 11 can be pressed down, so that the vertical rod 12 drives the scraper 10 to move downward to scrape off the sundries. The sundries fall on the first heating mesh 7 and the second heating mesh 8. The first heating mesh 7 and the second heating mesh 8 heat the incompletely melted material particles, and after heating, they flow out from the mesh holes. The impurity particles in the material will remain on the first heating mesh 7 and the second heating mesh 8 and can be taken out after the work is completed.
