Description of the invention (/) < Background of the invention > 1. Field of the invention The present invention relates to a grease stack with an elastic structure and the production of the resin stack Method, and more particularly relates to a low-cost elastic structural resin pallet for pads and a method for manufacturing the same, the resin pallet having excellent seismic performance, load capacity and durability, and Features such as long service life, light weight, and can be easily manufactured at the same time. < Explanation of the related technology > Generally speaking, wooden pallets are widely and frequently used in shipping or forklift trucks to transport goods. This is because the fabric pallets are light in weight and It has a coefficient of friction that is large enough to make it difficult for the goods on the pallet to slide on the surface of the pallet. In addition, it can immediately absorb the moisture attached to the surface of the pallet to prevent the goods from being wet by water. This type of wooden floor has a body composed of a plurality of upper and lower elongated wooden blocks arranged in parallel with each other at a predetermined space interval and connected by a wooden flat plate with screws and nails. The hollow space surrounded by the wooden flat plate and the long wooden block is a fork insertion hole for a fork of the forklift stacker. Although the advantages of the most commonly used wooden pallets of today are: they are low in manufacturing cost and have a certain strength; but they also have disadvantages: their weight is often very heavy and it is easy to absorb Water, so that they are easily susceptible to decay and have a short service life. In addition, they tend to be quickly soiled, which makes them difficult to use in the food and pharmaceutical industries. Going one step further, when they are stored 4 paper sizes are applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) —--------- Installation -------- Order- -------- Line (please read the notes on the back before filling this page) 509617 A7 B7 V. Description of the invention (y) When placed in an open courtyard or stacking yard, the lower half of the pallet It will contain a lot of rainwater due to absorption and will quickly rot. (Please read the cautions on the back before filling out this page.) On the other hand, plastic pallets have a complex rib structure to reduce their weight. The manufacturing of a plastic pallet is made by injection molding to make the top and bottom of the pallet, respectively, to become independently separated pallet components, and then these components are assembled by fusion bonding. Although plastic pallets have a long service life and are difficult to be contaminated, their manufacturing cost is much higher than that of wooden pallets, and they have poor durability and shock resistance. More specifically, the structure of traditional plastic pallets is designed to have a rib structure, so that the plastic pallet structure has greater strength, because their specific gravity is lighter than that of wood. The ribs of the pallet are so thin that stress concentration may occur there. Thus, although they have shown a longer service life than wooden pallets, they may be deformed and cracked after a long period of use. In addition, pallets made of steel exhibit very high strength, but they are very high in weight and cause corrosion. The present invention is printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economics to provide a solution to the above problems, and its purpose is to provide a resin pallet with an elastic structure that can prevent stress concentration and allow long-term usage of. Furthermore, because the conventional resin pallet has a complicated shape, it is necessary to mold each part by injection, injection compression, or extrusion compression. In particular, it needs to mold the individual parts with corresponding molds, and perform fusion welding and assembly operations to complete. Therefore, the other paper of the present invention 5 The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economy 509617 A7 B7 V. The description of the invention (3) A resin pallet. The resin pallet can be easily completed with a single molding device and a single mold, and the resin pallet has the desired characteristics. Excellent shock resistance and load capacity. Still another object of the present invention is to provide a resin pallet having the desired physical characteristics of shock resistance and load capacity 'and having a rib structure at the same time. < Summary of the invention > The resin pallet with elastic structure of the present invention is a pallet with a three-dimensional three-dimensional structure with a predetermined unit volume weight and voids. The three-dimensional three-dimensional structure is adjacent, tangled and aggregated Thermoplastic resin continuous fibers and / or short fibers formed by random loops or crimps are formed by: each individual pallet at the fork insertion hole of the pallet at both ends along its length and at this end There are high-density structural parts that increase the unit volume weight at the approximate center of the pallet in the direction. These high-density structural parts extend along the length of the fork insertion hole to both ends of the fork insertion hole, and are inserted along the fork. The width direction of the hole extends to both ends of the fork insertion hole. The single pallet has flat portions at least on the inner surface of the fork insertion hole or the outer periphery and inner surface of the fork insertion hole. The unit volume weight is not greater than the unit volume weight < amount of the high-density structure portion. 1 至 3.
