Description

Technical Field

[0001] The utility model relates to the field of sole forming machines, in particular to a forming machine tilting mechanism for the sole forming machine. Background Art

[0002] TPU foam particles are microporous materials with stable structures obtained by foaming TPU raw materials through physical or chemical methods. Their diameter is generally between 5mm and 7mm. Foam materials have their unique advantages, including: 1) excellent impact load resistance. When the foam plastic is subjected to impact compression, the internal bubbles play a role of compression rebound, consuming the impact energy, and thus have better cushioning and shock absorption functions; 2) excellent thermal insulation performance. The bubbles inside the polymer are filled with gas. However, the heat transfer coefficient of gas is generally lower than that of polymer. At the same time, the pores can prevent air convection, so the foam plastic has a thermal insulation function; 3) high specific strength. The ratio of material strength to material relative density is called specific strength. The strength of foam plastic is slightly lower than that of raw materials, while the density is greatly reduced. Therefore, the specific strength of foam plastic is usually larger.

[0003] The existing TPU foaming process used in shoe material production is the TPU foaming process. The so-called "TPU foaming process" is actually like popcorn. The TPU is made into granules. You can think of these granules as grains of old corn, and then thrown into a machine, which is similar to a popcorn machine. After high temperature and high pressure, these corns become popcorn. Then, a steam molding process is used to process about 2,000 popcorn grains into the required sole shape. In this process, the outermost layer of the foamed particles is slightly melted and adhered into a stable shape. At the same time, the internal pore structure is not affected, so that the formed popcorn sole has many advantages such as soft texture, good elasticity, good cushioning performance, low pressure energy loss, good durability, and good thermal insulation performance. Its surface presents a granular appearance and texture, which is favored by many consumers.

[0004] The existing Chinese utility model patent with publication number CN221659904U discloses a vertical and horizontal multifunctional integrated molding machine with a flipping structure. The flipping mechanism drives the flipping frame to switch between vertical and horizontal modes. When the flipping frame is vertical, workers can conveniently put in inserts and then process soles with bottom plates and or carbon plates, solving the problem that the guide columns are deformed and bent during the previous horizontal structure mold closing process, thereby affecting the service life. When the flipping frame is flipped by the flipping mechanism and changed to horizontal mode, the flipping frame is parallel to the frame. At this time, the sole molding device is directly demolded, and the molded sole falls to the bottom of the frame and is transported to the frame by the subsequent conveyor belt, realizing rapid unloading and thus improving production efficiency. The entire process improves the service life and processing efficiency of the equipment by switching between horizontal and vertical states, and processes soles with bottom plates and or carbon plates in a low-cost manner, thereby improving the diversity of product processing of the equipment.

[0005] However, in the above technical solution, the sole forming machine needs to switch between vertical and horizontal processing when forming each set of soles, which makes the entire equipment consume a lot of energy and the processing time too long. It is urgent to design a sole forming machine that can realize portable installation of inserts, convenient unloading, and does not require frequent switching to improve the efficiency of sole forming.

After unloading, the soles can be easily pushed out of the fixed die group and fall onto the conveyor belt below for output due to the tilting setting of the forming frame. The tilting drive mechanism can conveniently adjust the tilt angle of the forming frame to adapt to the processing environment of different soles. For example, when processing soles that do not require inserts, it is adjusted to 0°. The entire mechanism enables the molding machine to realize portable installation of inserts and convenient unloading, and solves the problems of excessive energy consumption and low efficiency caused by the need to frequently switch between vertical and horizontal types in the existing technology.
