Description

Technical Field

[0001] This utility model relates to the field of cold pressing technology, and in particular to a cold pressing machine for flooring substrates. Background Technology

[0002] In the flooring production and processing process, the cold pressing of the flooring substrate is a key step in ensuring the quality of the flooring. It involves applying a certain pressure to the substrate using cold pressing equipment and maintaining it for a period of time, so that the adhesive in the substrate can be fully cured, thereby forming a flooring substrate with a stable structure and qualified strength.

[0003] Currently, flooring substrate cold pressing machines on the market typically consist of a frame, an upper pressing mechanism, a lower pressing mechanism, and a drive unit. The upper and lower pressing mechanisms are arranged correspondingly. The flooring substrate to be cold pressed is placed on the lower pressing mechanism, and the drive unit moves the upper pressing mechanism downwards, working in conjunction with the lower pressing mechanism to perform the cold pressing operation on the flooring substrate.

[0004] Existing cold-press forming equipment for flooring typically involves feeding raw materials into a mold in a pressing mechanism, where they are then extruded to form the flooring substrate. However, in actual production, the high pressure required during the cold pressing process causes the flooring substrate to undergo elastic and plastic deformation under pressure. Its edges and bottom become tightly adhered to the inner wall of the lower mold, increasing the difficulty of demolding. Operators often need to use tools to demold the substrate, which can easily cause edge damage and surface scratches, affecting the product's appearance and structural integrity. This also increases the processing cycle and reduces production efficiency. Therefore, a cold-press forming machine for flooring substrates needs to be designed.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] This utility model provides a cold pressing molding machine for floor substrates to solve the problem that when existing cold pressing molding equipment processes flooring, the substrate is deformed by high pressure and adheres to the mold, making it difficult to demold, and manual demolding with tools easily damages the substrate.

[0007] This utility model embodiment adopts the following technical solution: a cold pressing molding machine for flooring substrate. It mainly includes a processing table, on which a lower mold for placing flooring raw materials and an upper mold adapted to the lower mold are provided. A demolding assembly is disposed within the processing table. The demolding assembly includes a support part disposed inside the processing table and located directly below the lower mold for supporting the flooring raw materials. The support part includes a crossbeam, and a magnetic suction part for simultaneous demolding after cold pressing is provided on the support part. The magnetic suction part includes an electromagnet one fixed to both ends of the crossbeam by a mounting bracket. Vertical rods are mounted on both sides of the upper mold via mounting seats, and an electromagnet two is fixed on the vertical rods. A reset part is provided at the bottom of the lower mold for controlling the electromagnets to be de-energized.

[0008] Furthermore, the support includes a horizontal frame disposed within the processing table and positioned directly below the lower mold. Two sets of vertically arranged support rods are mounted on the horizontal frame. Slides are installed on both sides of the horizontal frame, and reinforcing rods parallel to the support rods are fixed inside the slides. One end of the two sets of reinforcing rods and one set of support rods is connected and fixed to a base plate. A through groove adapted to the base plate is opened at the bottom of the lower mold. A support base plate is connected between the two sets of base plates. By default, the support base plate is in contact with the bottom of the inner wall of the lower mold.

[0009] Furthermore, a frame-like support is installed on the processing table, and the second electromagnet and the first electromagnet are on the same vertical line. A switch is fixed at the top beam of the support, and the switch is used to control the energization of the first and second electromagnets.

[0010] Furthermore, the reset part includes support parts at both ends. Each support part includes a guide rod fixed between the bottom surface of the lower mold and the bottom end of the inner wall of the processing table. The guide rod is connected to the bottom surface of the lower mold and the bottom end of the inner wall of the processing table respectively through mounting plates at both ends. A sliding seat is slidably provided on the guide rod. An installation part is provided between the two sets of sliding seats. The installation part includes a support frame fixed between the sliding seats. A spring is provided between the support frame and the mounting plate. A vertical rod is fixed inside the spring on the mounting plate. The vertical rod passes through the support frame. A second switch is provided on the bottom surface of the upper mounting plate of one set of installation parts. The second switch is used to control the de-energization of electromagnet one and electromagnet two.

[0011] Furthermore, two sets of symmetrically distributed guide rods are connected between the processing table and the support. The two ends of the guide rods are connected to the upper surface of the processing table and the lower surface of the support respectively through fixed seats. Guide sliders that are adapted to slide with the guide rods are installed on both sides of the upper mold. In the default state, the position of the upper mold causes the guide sliders to press the switch.

[0012] Furthermore, the processing table is provided with two sets of guide plates on its side, and multiple sets of rollers are rotatably mounted on the guide plates along their own straight line direction.

[0013] Furthermore, the bottom surface of the lower mold is provided with a notch or groove to provide space for the support part to move up and down.

[0014] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0015] This flooring substrate cold pressing machine utilizes a combination of upper and lower molds on a processing table for cold pressing operations. A demolding assembly within the processing table, with a support section at the bottom of the lower mold containing a crossbeam supporting the flooring raw material, is used. Electromagnets one and two in the magnetic suction unit, linked by the upward movement of the upper mold, push the support section out of the molded substrate, replacing manual demolding. A reset section at the bottom of the lower mold de-energizes the electromagnets, allowing the support section to reset. This effectively solves the problems of traditional equipment where high pressure makes substrate demolding difficult, requiring manual tools and causing substrate damage and low efficiency. It ensures the integrity of the product's appearance and structure, shortens the processing cycle, and improves the automation and production efficiency of cold pressing operations, perfectly meeting the needs of cold pressing production of flooring substrates.

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1-5 As shown, this utility model embodiment provides a floor substrate cold pressing molding machine, including a cold pressing component 1. The cold pressing component 1 includes a processing table 11. A frame-structured support 12 is fixedly installed on the processing table 11. A hydraulic cylinder 13 is fixedly installed at the top crossbeam of the support 12, and the telescopic end of the hydraulic cylinder 13 is set downward. An upper mold 14 is fixedly installed at the bottom of its telescopic end. At the same time, a lower mold 16 is adapted to be set on the processing table 11 for receiving the floor substrate to be cold pressed.

[0028] Two sets of symmetrically distributed guide rods 15 are connected between the processing table 11 and the support 12. The two ends of the guide rods 15 are fixedly connected to the upper surface of the processing table 11 and the lower surface of the support 12 respectively through the fixed seats 151 to ensure structural strength. Guide sliders 152 that are slidably adapted to the guide rods 15 are fixedly installed on both sides of the upper mold 14. During the cold pressing operation, the hydraulic cylinder 13 drives the upper mold 14 to move vertically along the guide rods 15. By utilizing the sliding cooperation between the guide sliders 152 and the guide rods 15, the stability and alignment accuracy of the upper mold 14 during the pressing process are improved, so as to realize the cold pressing forming operation of the floor substrate on the lower mold 16.

[0029] like Figures 2-5As shown, a demolding component 2 is provided inside the processing table 11. The demolding component 2 is used to solve the problem of difficult demolding of the floor substrate after traditional cold pressing. The demolding component 2 is responsible for ejecting the floor substrate that has been cold pressed in the lower mold 16. The demolding component 2 includes a support part located inside the processing table 11 and at the lower end of the lower mold 16. At the same time, a notch 161 is provided on the bottom surface of the lower mold 16 to provide space for the support part to move up and down. The support part specifically includes a crossbeam 21 located inside the processing table 11 and at the lower end of the lower mold 16. Two sets of vertically arranged support rods 22 are mounted on the crossbeam 21. Slide seats 23 are fixedly installed on both sides of the crossbeam 21. Reinforcing rods 24 parallel to the support rods 22 are also fixed in the slide seats 23 to enhance the structural stability.

[0030] Furthermore, a base plate (not shown in the figure) is connected and fixed to one end of the two sets of reinforcing rods 24 and one set of support rods 22, and a through groove 162 adapted to the base plate is opened at the bottom of the lower mold 16 to ensure that the base plate can pass through vertically. A support base plate 27 is connected between the two sets of base plates to support the flooring raw material for cold pressing. In the default state, the support base plate 27 is attached to the bottom of the inner wall of the lower mold 16. During cold pressing, it supports the base material. During demolding, it can be moved upward as a whole through the support part, and the formed flooring base material is pushed out from the lower mold 16 with the help of the support base plate 27 to achieve convenient demolding.

[0031] Simultaneously, a magnetic suction part is provided on the crossbeam 21 to solve the problem of precise linkage demolding after cold pressing, so that when the upper mold 14 moves upward after cold pressing, it simultaneously drives the supporting base plate 27 to push out the formed floor substrate. (Reference) Figures 3-4 The magnetic attraction part includes an electromagnet 26 fixed to both ends of the crossbeam 21 by a mounting bracket 25. A through slot 111 is provided on the processing table 11 for the vertical rod 29 and the electromagnet 26 to pass through. The vertical rod 29 is fixedly installed on both sides of the upper mold 14 by a mounting base 28. An electromagnet 210 is fixed on the vertical rod 29, and the electromagnet 210 and the electromagnet 26 are in the same vertical line to ensure magnetic alignment. A switch 211 is fixed at the top crossbeam of the bracket 12. The switch 211 is used to control the energization of the electromagnet 26 and the electromagnet 210. In the default state, the position of the upper mold 14 causes the guide slider 152 to press the switch 211, so that the two are in the energized state, preparing for the magnetic linkage.

[0032] Furthermore, a reset part is provided at the bottom end of the lower mold 16 to control the electromagnet to de-energize and the support base plate 27 to reset. (Reference) Figures 3-4As shown, the reset part includes support parts at both ends. Specifically, the support part is a guide rod 213 fixed between the bottom surface of the lower mold 16 and the bottom end of the inner wall of the processing table 11. The guide rod 213 is connected to the bottom surface of the lower mold 16 and the bottom end of the inner wall of the processing table 11 respectively through mounting plates 215 at both ends. A sliding seat 214 is slidably provided on the guide rod 213. An installation part is provided between the two sets of sliding seats 214. The installation part includes a support frame 212 fixed between the sliding seats 214. A spring 216 is provided between the support frame 212 and the mounting plate 215. A vertical rod 217 is fixed on the mounting plate 215 and inside the spring 216. The vertical rod 217 passes through the support frame 212. A switch 218 is provided on the bottom surface of the upper mounting plate 215 of one set of installation parts. The switch 218 is used to control the de-energization of electromagnet 1 26 and electromagnet 210.

[0033] It should be noted that when the upper mold 14 moves down with the hydraulic cylinder 13 and approaches the lower mold 16 to cold press the raw material of the inner floor, refer to Figures 2-3 Electromagnet 1 26 and electromagnet 210 come into close contact; after cold pressing, the upper mold 14 moves upward with the hydraulic cylinder 13. At this time, the two are magnetically connected, which drives the cross frame 21 to move upward, and simultaneously causes the support frame 212 and the support base plate 27 to move upward. The support frame 212 moves upward and stretches the spring 216. The support base plate 27 moves upward and pushes out the floor substrate in the lower mold 16. When the support base plate 27 moves upward to the trigger switch 218, electromagnet 1 26 and electromagnet 210 are de-energized, the magnetic attraction fails, the spring 216 rebounds and drives the support base plate 27 to reset, completing one demolding cycle. As the upper mold 14 continues to move upward with the hydraulic cylinder 13, it resets to the initial state. At this time, the guide slider 152 presses the switch 211 again to energize electromagnet 1 26 and electromagnet 210, in preparation for the next ejection of the floor substrate.

[0034] In addition, combined Figure 1 As can be seen, two sets of guide plates 17 are also provided on the side of the processing table 11. Multiple sets of rollers are installed on the guide plates 17 along their own straight direction. When the floor substrate is pushed out of the lower mold 16 by the support base plate 27, these rollers can take advantage of the characteristics of low rolling friction to facilitate the operator or subsequent conveying mechanism to quickly pull out the pushed-out floor substrate, realize convenient unloading after cold pressing, and improve the overall production continuity and operation convenience of the equipment.

[0035] Working Principle: When the flooring substrate cold pressing machine of this invention is working, the flooring raw material to be processed is first placed on the support base plate 27 inside the lower mold 16. At this time, the support base plate 27 is in contact with the bottom of the inner wall of the lower mold 16, in its initial position. After starting the equipment, the hydraulic cylinder 13 begins to work, and its telescopic end pushes the upper mold 14 vertically downward along the guide rod 15. The sliding cooperation between the guide slider 152 and the guide rod 15 ensures that the downward movement of the upper mold 14 is stable and accurately aligned with the lower mold 16. As the upper mold 14 gradually approaches the lower mold 16, the electromagnets 210 on its two vertical rods 29 also move downward synchronously, eventually approaching and contacting the electromagnets 26 at both ends of the crossbar 21. At this time, the synchronously moving upper mold 14 continues to apply pressure to the flooring raw material inside the lower mold 16, completing the cold pressing operation. During this process, as the upper mold 14 leaves the initial position, the guide slider 152 no longer presses switch 211, but electromagnet 26 and electromagnet 210 are already in contact, ensuring the basis for subsequent linkage actions.

[0036] After cold pressing is completed, the telescopic end of the hydraulic cylinder 13 drives the upper mold 14 to move upward. At this time, electromagnet 1 26 and electromagnet 210 are energized and maintain magnetic connection. Therefore, when the upper mold 14 moves upward, it will synchronously drive the cross frame 21 to move upward. The upward movement of the cross frame 21 is transmitted to the substrate through the support rod 22 and the reinforcing rod 24, which in turn drives the support base plate 27 to move upward. At the same time, the slides 23 on both sides of the cross frame 21 slide along the inner wall of the processing table 11 to ensure the overall stability of the support part. During the upward movement of the support base plate 27, the cold-pressed floor substrate in the lower mold 16 is pushed, causing it to gradually detach from the inner wall of the lower mold 16, thus achieving demolding. At the same time, the upward movement of the cross frame 21 also drives the support frame 212 to slide upward along the guide rod 213, stretching the spring 216 to store elastic potential energy. When the support base plate 27 completely pushes the floor substrate out of the lower mold 16, the support frame 212 touches the switch 218, triggering the electromagnets 26 and 210 to be de-energized, the magnetism of the two disappears, and the magnetic linkage is released.

[0037] After the magnetic attraction is released, the stretched spring 216 releases its elastic potential energy, pulling the support frame 212 down along the guide rod 213 to reset. Then, through components such as the crossbeam 21 and support rod 22, it drives the support base plate 27 back to its initial position, where it is in contact with the bottom of the inner wall of the lower mold 16, completing the entire demolding and reset process. At this time, the ejected floor substrate is placed on the support base plate 27. The operator can easily pull the formed floor substrate out of the equipment using the rollers on the guide plate 17 on the side of the processing table 11, achieving convenient unloading. Meanwhile, the upper mold 14 continues to move upward to its initial position under the drive of the hydraulic cylinder 13. The guide slider 152 presses the switch 211 again, re-energizing the electromagnets 26 and 210, preparing for the next cold pressing and demolding operation. This cycle repeats continuously, achieving continuous cold pressing production of the floor substrate.
