Description

Technical Field

[0001] This utility model relates to the field of compression molding technology, specifically to a compression molding mold that can compress pallet legs. Background Technology

[0002] Pallet compression molding molds, in their core, refer to specialized molds used to produce wooden molded pallets. Their function is to press materials such as wood fibers, plastics, or thermosetting resins into the mold cavity under high temperature and pressure to form pallet products with specific structures and properties.

[0003] The forming grooves in the support legs of existing wooden pallets have a fixed and limited capacity, which can only hold a specific amount of raw material. When the raw material shrinks significantly during compression, the actual filling amount of raw material will be relatively insufficient due to the fixed capacity of the forming groove, which in turn leads to the problem of loose pallet support structure. Utility Model Content

[0004] The purpose of this invention is to provide a compression mold that can compress pallet legs, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A compression mold for a pallet support foot includes an upper mold and a lower mold. The lower mold includes a liftable and adjustable floating mold frame and multiple sets of support columns, the tops of which are located at the foot grooves of the floating mold frame.

[0006] Preferably, the lower mold further includes a base, and the floating mold frame and multiple sets of support columns are all disposed on the base.

[0007] Preferably, the base is provided with multiple sets of retractable lifting columns, and the output end of the retractable lifting columns is equipped with a connecting component that is externally fixedly connected to the floating mold frame.

[0008] Preferably, the base is provided with multiple sets of compression-molded support columns.

[0009] Preferably, a connecting plate is vertically mounted on the base, and the top of the connecting plate is fixedly connected to the bottom of the support column.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a telescopic lifting column to drive the floating mold frame to adjust its height, so that the floating mold frame can be separated from the top of the column. This allows the lower mold support groove to accommodate more material. Combined with the downward pressing of the upper mold, it can ensure that the pallet support is formed more fully and with higher dimensional accuracy. Furthermore, with the help of the connecting plate to drive the column to rise, the formed pallet support can be quickly ejected from the cavity, improving demolding efficiency and ensuring the smooth operation of the compression molding cycle.

[0016] Please see Figure 1-4A compression molding die for a pallet support includes an upper mold 1 and a lower mold. The lower mold includes a liftable and adjustable floating mold frame 3 and multiple sets of support columns 4. The top of the support columns 4 is located at the support groove of the floating mold frame 3. The upper mold 1 is a key component for compression molding, which cooperates with the lower mold to form a closed cavity. During the compression molding process, by applying downward pressure, the material in the cavity is compacted and shaped, ultimately forming a pallet product that meets the size and shape requirements. The base 2 is the installation foundation and bearing platform of the entire lower mold structure, providing stable support for other components (such as the floating mold frame 3, support columns 4, telescopic lifting columns 7, etc.). The support groove of the floating mold frame 3 cooperates with the top of the support column 4 to jointly form part of the cavity for forming the pallet support.

[0017] Please see Figure 2 and Figure 3 The lower mold also includes a base 2, a floating mold frame 3, and multiple sets of support columns 4, all mounted on the base 2. The base 2 has multiple sets of retractable lifting columns 7, with a connecting component 8 fixedly connected to the external surface of the floating mold frame 3 at the output end of each column. The base 2 also has multiple sets of compression molding support columns 5. A connecting plate 6 is retractably mounted on the base 2, with its top fixedly connected to the bottom of the support column 4. The retractable lifting column 7 is the power actuator that drives the floating mold frame 3 to rise and fall; its retractable movement adjusts the height of the floating mold frame 3. The connecting component 8 connects the retractable... The output end of the lifting column 7 is connected to the outside of the floating mold frame 3, which stably and effectively transmits the driving force of the retractable lifting column 7 to the floating mold frame 3, ensuring that the floating mold frame 3 can accurately rise and fall with the movement of the retractable lifting column 7. The support column 5 plays an auxiliary supporting role, dispersing pressure during the compression molding process, avoiding deformation of local structures due to excessive force, protecting device components, and extending service life. The connecting plate 6 is a bridge connecting multiple sets of support columns 4, connecting multiple sets of support columns 4 into a whole and transmitting power, transmitting the external driving force (lifting column) to the support column 4 to realize the lifting and adjustment of the support column 4.

[0018] Working principle: When the compression molding mold is working, firstly, the upper mold 1 moves upward and separates from the lower mold, providing space for material to be added. Then, through the telescopic movement of the telescopic lifting column 7, the height of the adjustable floating mold frame 3 is adjusted via the connecting component 8, so that the floating mold frame 3 separates from the top of the support column 4. At this time, the support groove of the lower mold can accommodate more material. After the material is added, the upper mold 1 moves downward to apply pressure. During the downward pressing of the upper mold 1, the telescopic lifting column 7 will drive the floating mold frame 3 to return to its original position. At this time, the top of the support column 5 contacts the bottom of the floating mold frame 3 to disperse the pressure and avoid local deformation. Under the action of pressure, the material in the cavity is compacted and shaped. After molding, the upper mold 1 is raised, and the connecting plate 6 drives the support column 4 to move upward through the external drive, so that the molded tray support is pushed out of the cavity, completing one compression molding cycle.

[0019] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
