Description

Technical Field

[0001] The utility model relates to the technical field of buffer mechanisms, in particular to a buffer mechanism of a plastic mould for a plastic pallet. Background Art

[0002] The cushioning mechanism of the plastic mold for plastic pallets is a key component to ensure that the mold can operate smoothly and safely during the mold closing process, while reducing mold damage and improving product quality. During the mold closing process, the cushioning mechanism can absorb impact energy and reduce direct collisions between molds, thereby protecting the mold from damage. The cushioning mechanism helps to reduce blemishes and defects on the product surface and improve the overall quality of the product.

[0003] In actual use, existing plastic molds often lack flexibility due to differences between molds, making adjustments based on actual conditions difficult. This can lead to mold sizes being inappropriate during installation. This mismatch not only delays installation but can also affect mold performance and even negatively impact production efficiency and product quality. These mold differences can stem from errors during the manufacturing process.

[0004] Therefore, in order to solve this problem, the present invention provides a buffer mechanism for a plastic mold for a plastic pallet. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0022] Reference Figures 1-4 A buffer mechanism of a plastic mold for a plastic pallet comprises an upper mounting frame 1 and a lower mounting frame 2. Mounting seats 3 are respectively provided on the sides of the upper mounting frame 1 and the lower mounting frame 2. A bidirectional threaded rod 4 is rotatably connected to the interior of the mounting seat 3 through a bearing. An adjustment seat 5 is connected to the surface of the bidirectional threaded rod 4 through a thread. A detachable fixing sleeve 6 is provided at the bottom of the lower mounting frame 2. A spring 7 is provided inside the fixing sleeve 6. A pushing block 8 is slidingly provided inside the fixing sleeve 6. A pushing rod 9 is provided on the top of the pushing block 8. One end of the pushing rod 9 is detachably provided on the upper mounting frame 1.

[0023] When the tool is in use, the staff rotates the bidirectional threaded rod 4, and the surface of the rotating bidirectional threaded rod 4 drives the adjusting seat 5 to move through the thread. By setting the thread on the surface of the bidirectional threaded rod 4 as a reverse thread groove, it is convenient to drive the two adjusting seats 5 to be adjusted at the same time. The staff installs the upper mounting frame 1 on the upper mold to be used, and installs the lower mounting frame 2 on the lower mold. When the upper mold moves downward, it drives the push rod 9 to move downward. The moving push rod 9 drives the push block 8 to squeeze the spring 7, thereby achieving a buffering effect, avoiding excessive speed during use, resulting in damage to the mold and affecting subsequent use.

[0024] Reference Figure 2 A threaded sleeve 101 is provided on the side of the upper mounting frame 1, and the threaded sleeve 101 is threadedly connected to the push rod 9.

[0025] In the present invention, the threaded sleeve 101 is provided to be threaded with the push rod 9, thereby facilitating installation and disassembly by the staff, and avoiding affecting the subsequent handling of the staff.

[0026] Reference Figure 2 The side of the threaded sleeve 101 is connected to the limit rod 10 through a thread, and the limit rod 10 passes through one end of the lower mounting frame 2 and is provided with a detachable limit seat 1001.

[0027] In the present invention, the limiting rod 10 is provided to slide inside the lower mounting frame 2, thereby facilitating the downward positioning of the push rod 9 and avoiding position deviation that affects the use effect.

[0028] Reference Figure 2 and Figure 4 The interior of the adjustment seat 5 is provided with a mounting groove 501 therethrough, and the number of the adjustment seat 5 is four.

[0029] In the present invention, the installation groove 501 is provided to facilitate the installation and use of the upper mounting frame 1 and the lower mounting frame 2 by the staff, thereby avoiding inconvenient installation and delaying the normal use of the staff.

[0030] Reference Figure 4 A guide edge 502 is provided on the side of the adjustment seat 5, and a guide groove 301 is opened on the side of the mounting seat 3. The guide edge 502 is slidably connected to the guide groove 301.

[0031] In the present invention, the sliding connection between the guide groove 301 and the guide edge 502 facilitates limiting the moving position of the adjustment seat 5 to avoid delaying subsequent use by staff.

[0032] Reference Figure 1 and Figure 2 A mounting sleeve 201 is provided on the side of the lower mounting frame 2, and the mounting sleeve 201 is threadedly connected to the fixing sleeve 6.

[0033] In the present invention, a threaded connection is provided between the installation sleeve 201 and the fixed sleeve 6, thereby facilitating the disassembly of the fixed sleeve 6 by the staff, and avoiding obstruction of the adjustment seat 5 during installation, thereby affecting the use effect.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
