Description

Technical Field

[0001] This utility model relates to the field of compression molding technology, specifically a compression molding mold for producing four-way forklift pallets. Background Technology

[0002] A four-way entry pallet is a logistics carrying device that allows the forks of a forklift or pallet truck to enter from four directions: front, rear, left, and right. A four-way entry pallet is usually composed of a top plate, foot blocks, and reinforcing ribs. When the longitudinal beams and foot blocks together form the fork entry opening, this type of pallet is called a true four-way entry pallet, and forklifts and pallet trailers can freely enter from any direction.

[0003] The compression molds used in the production of four-way forklift pallets currently consist of an upper mold and a lower mold. The lower mold is equipped with a cavity for holding the raw material. The pallet is pressed and formed by closing and cooperating with the upper mold. However, the cavity size of traditional compression molds is fixed, which makes it difficult to control the amount of raw material filling accurately. The fixed cavity design cannot dynamically adjust the distribution of raw material according to the product structure characteristics, resulting in material redundancy in non-load-bearing areas, which directly increases the manufacturing cost per unit. Utility Model Content

The pallet body is provided with multiple sets of support legs and reinforcing ribs. The lower mold is provided with a cavity that mates with the pallet. The lower mold includes a floating mold frame and floating ribs that can be adjusted for height.

[0006] Preferably, the lower mold further includes a base, and the floating mold frame and the floating rib are both movably and limitably mounted on the base.

[0007] Preferably, the floating rib includes multiple sets of pillars with their tops located at the reinforcing rib cavities of the floating mold frame and connecting seats located at the bottom of the multiple sets of pillars.

[0016] Please see Figure 1-5 A compression mold for producing four-way forklift pallets includes an upper mold 1, a lower mold, and a pallet body 3. The pallet body 3 is provided with multiple sets of support legs 4 and reinforcing ribs 5. The lower mold is provided with a cavity that mates with the pallet. The lower mold includes a floating mold frame 6 and a floating rib 8 that can be raised and lowered. The lower mold also includes a base 2. The floating mold frame 6 and the floating rib 8 are both limited and movable on the base 2. The upper mold 1 is the upper pressing component of the mold, which cooperates with the cavity of the lower mold to form a closed molding space. During the compression molding process, the upper mold 1 applies downward pressure to compact the raw material into the cavity of the lower mold, causing the raw material to conform to the shape of the cavity and form the structure of the pallet. The lower mold is the lower half of the mold and is the core carrier for pallet forming. It integrates adjustment and support components such as floating mold frame 6, floating rib 8 and column 7. It cooperates with the upper mold 1 to complete the entire compression molding process of the pallet. The pallet body 3 is the target product of the mold. The legs are the supporting structure of the pallet, which bears the weight and forms the fork entry opening. The reinforcing ribs are the reinforcing structures that connect multiple sets of legs, enhance the overall rigidity of the pallet and prevent deformation.

[0017] Please see Figure 3 and Figure 4 The floating rib 8 includes multiple sets of pillars with their tops located at the reinforcing rib cavities of the floating mold frame 6 and connecting seats located at the bottom of the multiple sets of pillars. The tops of the pillars cooperate with the reinforcing rib cavities of the floating mold frame 6, and the connecting seats are fixedly connected to the output end of the external lifting mechanism. The base 2 is the basic support component of the lower mold, which fixes and installs all lower mold components such as the floating mold frame 6, floating ribs 8, lifting columns 9, uprights 7, and support columns 10. It provides a stable installation platform, ensures the relative positional accuracy of each component, bears the pressure during the compression molding process, and avoids overall structural deformation. The floating mold frame 6 is the core cavity frame of the lower mold, which is limited and movable on the base 2. The floating ribs 8 are the core components for adjusting the volume of the reinforcing rib cavity of the floating mold frame 6, solving the waste and molding defects caused by excessive raw material. The top of the column cooperates with the reinforcing rib cavity of the floating mold frame 6 and is connected to an external lifting mechanism through a connecting seat, so that the height of the column can be raised and lowered.

[0018] Please see Figure 4The base 2 is provided with a lifting column 9, and the output end of the lifting column 9 is fixedly connected to the outside of the floating mold frame 6. Multiple sets of columns 7 are fixedly provided on the base 2. The top of the column 7 is located at the support cavity of the floating mold frame 6, and the top of the column 7 cooperates with the support cavity of the floating mold frame 6. The lifting column 9 is the power component that drives the floating mold frame 6 to rise and fall. Its output end is fixed to the outside of the floating mold frame 6. The height of the floating mold frame 6 can be adjusted by telescoping. When the floating mold frame 6 is raised, it will separate from the top of the column 7, so that the cavity at the upper tray support of the lower mold can accommodate more raw materials.

[0019] Please see Figure 2 and Figure 4 The base 2 is provided with multiple sets of support columns 10 whose tops are in separate contact with the bottom of the floating mold frame 6; The support column 10 is an auxiliary support and limiting component of the floating mold frame 6. Its top is in separate contact with the bottom of the floating mold frame 6. When the floating mold frame 6 descends to a certain position, the support column 10 contacts and supports the floating mold frame 6 to prevent it from descending too far and causing structural damage. It provides additional support during the compression molding process, enhances the load-bearing capacity of the floating mold frame 6, and avoids cavity deformation due to excessive pressure.

[0020] Working principle: First, the floating mold frame 6 is driven to rise from the base 2 by the telescopic adjustment of the lifting column 9. At this time, the floating mold frame 6 separates from the top of the column 7, and the cavity space at the corresponding tray support 4 on the lower mold increases, which can accommodate more raw material. At the same time, the floating rib 8 adjusts the height of the support column through the external lifting mechanism, so that the cavity volume of the reinforcing rib of the floating mold frame 6 is adapted to the amount of raw material. After the raw material is added, the upper mold 1 moves downward and cooperates with the cavity of the lower mold to form a closed molding space. The upper mold 1 applies pressure to compact the raw material in the cavity, promoting... The raw material is molded into a tray body 3 with support legs 4 and reinforcing ribs 5. During the compression molding process, the floating ribs 8 and the floating mold frame 6 will return to their original positions. The bottom of the connecting seat will contact the top of the base 2, while the support column 10 will contact the bottom of the floating mold frame 6 to provide auxiliary support and prevent the cavity from deforming due to excessive pressure. After molding, the upper mold 1 is raised, and the floating mold frame 6 and the floating ribs 8 are reset under the action of the corresponding driving mechanism, making it easy to remove the molded tray body 3 from the cavity and complete one compression molding cycle.

[0021] 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.
