Characteristics and Classification of 1. Pallet Mould

As a standardized basic instrument of modern logistics and warehousing industry, pallets bear the key functions of cargo carrying, handling and storage. As the core tool for the production of pallets, the pallet mold is the key to ensure the quality, performance and production efficiency of the pallet. Driven by injection molding technology, injection pallet molds have become the mainstream choice for pallet production because of their high efficiency, flexibility and low cost. This paper will deeply analyze the characteristics, technical points and industry application of injection pallet mold. Pallet mold has the following characteristics:

1. Large-scale and high-strength design

Pallet sizes are generally large (common specifications are1200mmx1000mm,1100mmx1100mm), the mold needs to adapt to large-size cavities, and needs to withstand up100~200Tons of injection pressure. In order to ensure that the mold does not deform under high pressure, thickened mold frame, high-strength mold steel (suchP20,718h), and enhance the rigidity of the mold by optimizing the layout of reinforcing ribs.

2.Structural Complexity and Functional Integration

Pallets need to take into account the carrying capacity, anti-skid performance, forklift/AGVAdaptability and other functions, mold design needs to integrate a variety of structures:

Reinforcement system: through the three-dimensional grid or Sichuan-shaped reinforcement design, improve the rigidity of the pallet, the mold needs to accurately control the thickness and spacing of the ribs;

Anti-slip texture: in the mold surface processing point, striped texture, to ensure the safety of cargo handling;

Fork hole structure: precise design of fork hole size and tilt angle, suitable for different types of handling equipment.

3.Multi-cavity design and productivity

In order to meet the massive demand for pallets in the logistics industry, molds often use multi-cavity designs (such2Cavity,4cavity), and with hot runner technology to achieve synchronous injection molding, the single-piece production cycle is compressed.30~60seconds, significantly increase production capacity

According to the material and structure of the pallet, the pallet mold can be divided into plastic pallet mold, metal pallet mold and composite pallet mold. Among them, the plastic tray mold is the most widely used, because the plastic tray has the advantages of light weight, corrosion resistance, low cost and so on. Plastic pallet mold can be divided into flat pallet mold, grid pallet mold, Sichuan word pallet mold, Tian word pallet mold and so on according to the shape and function of the pallet.

Second, the design points of the pallet mold

1.Product Analysis and Process Planning:

Before designing a pallet mold, it is necessary to analyze the pallet product in detail, including the size, shape, carrying capacity, and use environment of the pallet. According to product requirements, formulate a reasonable injection molding process plan, determine the model of the injection molding machine, injection pressure, injection speed, holding time, cooling time and other process parameters.

2.mold structure design:

Parting surface design: The choice of parting surface directly affects the structure of the mold and the demolding method of the pallet. The appropriate parting surface should be selected according to the shape and size of the tray to ensure that the tray can be demoulded smoothly, while minimizing the difficulty and cost of mold processing.

Gating system design: Due to the large size of the tray, it is necessary to design the gating system reasonably to ensure that the plastic melt can fill the cavity evenly. Multi-point pouring is usually used to shorten the flow distance of the plastic and reduce the generation of weld lines. At the same time, pay attention to the location and size of the gate to avoid gate marks affecting the appearance and performance of the tray.

  Cooling system design: The cooling system design of the pallet mold is very important, which directly affects the production efficiency and quality of the pallet. Due to the large size of the tray and the wide cooling area, it is necessary to design a reasonable cooling water circuit to ensure that the mold can be cooled quickly and evenly. The cooling efficiency can be improved by circulating water cooling, optimizing the layout of cooling pipes, and increasing the flow rate of cooling medium.

The design of the ejection system: the tray needs a large ejection force when demolding, so the design of the ejection system should be reasonable and reliable. Usually, a combination of ejector pins, ejector blocks, push plates and other ejection methods is used to ensure that the tray can be ejected smoothly from the mold to avoid ejection deformation or damage.

Reinforcing ribs and structural design: In order to improve the carrying capacity and rigidity of the pallet, it is necessary to set reinforcing ribs at the appropriate position of the pallet. In the mold design, it is necessary to accurately reflect the shape and position of the reinforcing ribs to ensure the forming quality of the reinforcing ribs. At the same time, the structural strength of the mold should be considered to prevent the mold from being deformed or damaged during the injection molding process.

3, material selection and die life:

Pallet molds usually need to withstand greater injection pressure and frequent mold opening and closing actions, so the strength, wear resistance and toughness of the mold material are required to be high. General selection of high quality die steel, suchP20,718And carry out appropriate heat treatment to improve the service life of the mold. In addition, in the mold design, it is necessary to reasonably design the structure of the mold and the size of the parts to avoid stress concentration and extend the service life of the mold.

Manufacturing and Quality Control of Pallet Mould

1.Manufacturing process: The manufacturing process of the pallet mold is similar to that of the ordinary injection mold, but due to its large-scale and complex structure, some special problems need to be paid attention to during the processing. For example, the processing of large molds requires the use of large processing equipment, such as large CNC machining centers, gantry milling machines, etc., to ensure machining accuracy and efficiency. For complex structural components, it may be necessary to use special processing techniques such as EDM and wire cutting. In the process of mold assembly, it is necessary to strictly control the matching accuracy of the parts to ensure the overall performance of the mold.

2.Quality control: The quality of the pallet mold directly affects the quality and production efficiency of the pallet. In the mold manufacturing process, it is necessary to establish a strict quality control system, from raw material inspection, processing process monitoring to finished product inspection, every link must be strictly controlled. Adopt advanced detection equipment and detection methods, such as three-coordinate measuring instrument, optical projector, etc., to detect the key size and shape of the mold to ensure that the accuracy of the mold meets the design requirements. At the same time, it is necessary to test and debug the mold, test the molding performance and product quality of the mold through the mold, find and solve problems in time, and ensure that the mold can be put into production normally.
