This device effectively heats and cools the rubber material using a compressor, evaporator, heating element, and fan, ensuring normal production. However, after processing, the device requires manual demolding. Due to the limited space inside the mold core, manual removal is difficult and time-consuming, resulting in the device being unable to produce continuously, greatly reducing production efficiency and making it difficult to meet the needs of mass production. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a decorative panel forming mold unloading device to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a material removal device for a decorative panel forming mold, comprising a lower mold and an upper mold. A lower mold core is fixedly connected to the upper surface of the lower mold, and a base is fixedly connected to the lower surface of the lower mold. An upper mold core is fixedly connected to the lower surface of the upper mold. Two symmetrical clearance openings are provided on both the lower mold core and the lower mold. A top block is slidably connected to each of the two clearance openings. The bottom ends of the two top blocks are fixedly connected to a connecting plate through the top inner wall of the lower mold. Springs are fixedly connected to the four corners of the lower surface of the connecting plate, and the bottom ends of multiple springs are fixed to the upper surface of the base. A limiting component is provided between the base and the top blocks to limit the vertical movement of the top blocks. A pushing component is provided on the lower mold to push the material out of the mold.

[0006] As a further embodiment of this utility model, the limiting component includes two sets of limiting ports symmetrically opened near the lower position of the two top blocks, and each set has two ports. A horizontal plate is slidably connected in each of the two sets of limiting ports. A vertical plate is fixedly connected to both ends of the lower surface of the two horizontal plates, and the bottom end of the vertical plate is fixed to the upper surface of the base.

[0007] As a further embodiment of this utility model, the pushing component includes two symmetrical sliding openings II located on the upper surface of the lower mold and on both sides of the lower mold core. Each of the two sliding openings II is slidably connected to a push rod. One side of the lower mold has two symmetrical sliding openings I, each of the two sliding openings I is slidably connected to a U-shaped plate. Two symmetrical connecting rods are fixedly connected to the inner wall of one side of the U-shaped plate. The other ends of the two connecting rods are respectively fixed to the bottom ends of the two push rods. The lower mold is provided with a driving component for moving the U-shaped plate.

[0008] As a further embodiment of this utility model, the driving assembly includes a cylinder fixedly connected to one side of the lower mold, and a fixing plate fixedly connected to the output end of the cylinder, with one side of the fixing plate fixed to one side of the outer wall of the U-shaped plate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, through the provision of a top block and a spring, lifts the shaped workpiece after it is squeezed out of the mold, so that it is no longer in contact with the lower mold core, making it convenient for workers to remove. This ensures the continuity of production while speeding up the mold forming process, thereby greatly improving production efficiency.

[0014] 2. This utility model can limit the displacement distance of the top block by means of a limiting component, so as to prevent the workpiece above the top block from being unable to be effectively squeezed and shaped during the mold pressing and shaping process, thus preventing the production of defective products and ensuring the integrity of the workpiece output.

[0015] 3. The present invention uses a push assembly that only requires the cylinder to be activated to drive multiple components to move, thereby pushing the lifted workpiece out of the mold without the need for manual removal. This reduces labor costs while increasing the automation effect and safety of the device. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1-4This utility model provides a material removal device for a decorative panel forming mold, including a lower mold 2 and an upper mold 3. A lower mold core 4 is bolted to the upper surface of the lower mold 2, and a base 1 is bolted to the lower surface of the lower mold 2. An upper mold core 5 is bolted to the lower surface of the upper mold 3. Both the lower mold core 4 and the lower mold 2 have two symmetrical clearance openings 7. A top block 8 is slidably connected to each of the two clearance openings 7. The bottom ends of the two top blocks 8 pass through the top inner wall of the lower mold 2 and are bolted to a connecting plate 15. Springs 16 are welded to the four corners of the lower surface of the connecting plate 15, and the bottom ends of multiple springs 16 are fixed to the upper surface of the base 1. A limiting component is provided between the base 1 and the top blocks 8 to limit the vertical movement of the top blocks 8. A pushing component 6 is provided on the lower mold 2 to push the material out of the mold. When the workpiece is extruded and shaped, it is first placed on the lower die core 4, and then extruded and shaped by the upper die core 5 on the upper die 3 and the lower die core 4 on the lower die 2. At the same time, the extrusion top block 8 moves downward along the relief opening 7, which causes the connecting plate 15 to move downward and the extrusion spring 16 to be compressed. After the shaping is completed, the upper die 3 moves upward and the upper die core 5 separates from the lower die core 4. At this time, the spring 16 releases its elastic force and pushes the connecting plate 15 upward, which causes the top block 8 to move upward along the relief opening 7. At the same time, the top of the top block 8 lifts the shaped workpiece from the surface of the lower die core 4. Through the provided top block 8 and spring 16, after the workpiece is extruded and detached from the die, the shaped workpiece is lifted up and separated from the lower die core 4, making it easy for the staff to remove. This ensures the continuity of production and speeds up the die shaping process, thereby greatly improving production efficiency.

[0023] In this utility model, the limiting component includes two sets of limiting ports 17 symmetrically located near the lower part of the two top blocks 8, with two ports in each set. A horizontal plate 18 is slidably connected within each of the two sets of limiting ports 17. Vertical plates 19 are bolted to both ends of the lower surfaces of the two horizontal plates 18, and the bottom ends of the vertical plates 19 are fixed to the upper surface of the base 1. Telescopic rods 20 are bolted to the lower surface of the connecting plate 15 between the lower surface of the connecting plate 15 and the upper surface of the base 1, located at the center of multiple springs 16. When the elastic force is fully released, the bottom inner wall of the limiting port 17 contacts the lower surface of the horizontal plate 18. When the top block 8 is fully slid into the relief port 7, the top inner wall of the limiting port 17 contacts the upper surface of the horizontal plate 18. At this time, the top of the top block 8 is flush with the surface of the lower mold core 4. The distance of displacement of the top block 8 can be limited by the limiting component, so as to prevent the workpiece above the top block 8 from being effectively squeezed and shaped during the mold pressing and shaping process, thus producing defective products and ensuring the integrity of the workpiece output.

[0024] To facilitate the removal of the shaped workpiece, the pushing assembly 6 includes two symmetrical sliding openings 11 on the upper surface of the lower mold 2 and located on both sides of the lower mold core 4. Each sliding opening 11 contains a push rod 14. Two symmetrical sliding openings 9 are provided on one side of the lower mold 2, each containing a U-shaped plate 10. Two symmetrical connecting rods 12 are bolted to the inner wall of one side of the U-shaped plate 10. The other ends of the connecting rods 12 are fixed to the bottom ends of the two push rods 14. The lower mold 2 is equipped with a driving assembly for moving the U-shaped plate 10. The driving assembly includes a cylinder 1301 bolted to one side of the lower mold 2. A fixing plate 1302 is bolted to the output end of the cylinder 1301. One side of the fixing plate 1302 is fixed to the outer wall of one side of the U-shaped plate 10. The two push rods 14... Two limiting blocks 21 are fixedly connected to the outer circumference of the lower mold 2 by bolts. The two limiting blocks 21 are located on the outer side of the top outer wall and the inner side of the top inner wall, respectively. After the workpiece is lifted, the cylinder 1301 is activated to retract. During the retraction of the cylinder 1301, the U-shaped plate 10 is driven to move along the slide 19 towards the lower mold 2 through the fixing plate 1302 at its end. During the movement of the U-shaped plate 10, the two push rods 14 at its end are moved along the two slides 11 through the connecting rod 12, thereby pushing the lifted workpiece and making it leave the mold. With the provided pushing component 6, multiple parts can be driven to move by only activating the cylinder 1301, thereby pushing the lifted workpiece out of the mold without manual removal. This reduces labor costs and increases the automation effect and safety factor of the device.

[0025] To achieve precise positioning between the molds, positioning rods 22 are fixedly connected to the four corners of the lower surface of the upper mold 3 by bolts, and positioning holes 23 that cooperate with the positioning rods 22 are opened at the four corners of the upper surface of the lower mold 2. The upper mold 3 and the lower mold 2 can be precisely positioned when they are working.

[0026] The use of this utility model involves the following steps:

[0027] S1: When it is necessary to extrude and shape the workpiece of the decorative panel, first place the workpiece on the lower die core 4, and then extrude and shape it by the upper die core 5 on the upper die 3 and the lower die core 4 on the lower die 2. At the same time, the extrusion top block 8 moves downward along the clearance 7, thereby causing the connecting plate 15 to move downward and the extrusion spring 16 to be compressed.

[0028] S2: After the shaping is completed, the upper mold 3 moves upward and the upper mold core 5 separates from the lower mold core 4. At this time, the spring 16 releases its elastic force to push the connecting plate 15 upward, which in turn causes the top block 8 to move upward along the clearance opening 7. At the same time, the top of the top block 8 lifts the shaped workpiece from the surface of the lower mold core 4.

[0029] S3: When the spring 16 is fully released, the bottom inner wall of the limiting port 17 contacts the lower surface of the horizontal plate 18. When the top block 8 is fully slid into the relief port 7, the top inner wall of the limiting port 17 contacts the upper surface of the horizontal plate 18. At this time, the top of the top block 8 is flush with the surface of the lower mold core 4.

[0030] S4: After the workpiece is lifted, the cylinder 1301 is activated to retract. During the retraction of the cylinder 1301, the U-shaped plate 10 is driven to move along the slide 19 towards the lower mold 2 through the fixing plate 1302 at its end. During the movement of the U-shaped plate 10, the two push rods 14 at its end are moved along the two slides 11 through the connecting rod 12, thereby pushing the lifted workpiece and causing it to leave the mold.

[0031] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
