DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Example 1.

[0022] like Figure 1 As shown, the foaming hot mold clamping tooling for the trunk cover described in this embodiment includes a body 1, and a clamping mechanism 2 and a driving mechanism 3 arranged on the body 1, the clamping mechanism 2 includes a fixed mold 21 and a movable mold 22 arranged relatively, and the interiors of the fixed mold 21 and the movable mold 22 are both provided with heating pipes 23 connected to the external heating system; the heating pipes 23 are evenly distributed inside the fixed mold 21 and the movable mold 22, and are used to heat the fixed mold 21 and the movable mold 22; the body 1 is also provided with a support frame 4, and the support frame 4 is fixedly connected to the body 1 through a plurality of guide slides 6, and the driving mechanism 3 is fixedly mounted on the support frame 4, the guide slide column 6 is provided with a mounting seat 5 fixedly connected to the power output end of the driving mechanism 3, the movable mold 22 is mounted on the mounting seat 5 and moves up and down relative to the fixed mold 21 along the axial direction of the guide slide column 6 under the drive of the driving mechanism 3; the fixed mold 21 and / or the movable mold 22 are also provided with a pressure-maintaining mechanism 7, the pressure-maintaining mechanism 7 is used to maintain the pressure of the trunk cover after the mold clamping mechanism 2 is closed, and the mold cavities of the fixed mold 21 and the movable mold 22 are provided with matching convex molds 11, the convex mold 11 is used to print the predetermined components after the trunk cover is solidified. In this embodiment, the driving mechanism 3 can be a cylinder or a hydraulic cylinder.

[0023] When working, Figure 1 and Figure 2As shown, the external heating system 100 is started to transport the heating medium to the heating tube 23, so that the heating tube 23 provides heating function for the fixed mold 21 and the movable mold 22. When the temperature of the two molds reaches the set value, the water-based mold release agent is coated in the mold cavity, and the trunk cover sprayed with the foaming material is placed in the fixed mold 21. The rear driving mechanism 3 drives the movable mold 22 to close toward the fixed mold 21. After the two molds are completely closed, the pressure holding mechanism 7 applies pressure for a period of time. At this time, the trunk cover is fully expanded and foamed in the closed mold cavity, completely and tightly fills the inside of the mold cavity and is squeezed into the punch 11 and solidifies its shape, thereby forming a preset component. Then, after the trunk cover is completely solidified, the driving mechanism 3 drives the movable mold 22 to reset and open, and the molded trunk cover product can be taken out. This embodiment uses efficient and rapid molding in the heated mold, and uses the cover plate to expand and foam in the closed mold cavity to print components that match the punch 11, such as the cover plate drawstring hole or the groove structure that matches the external accessories, etc., which meets the performance of light weight, shock resistance, and sound insulation, while achieving fast and accurate one-step molding, effectively simplifying the production process, shortening the product molding cycle, and improving production efficiency. In this embodiment, the molding pressure of the movable mold 22 is 15±1bar, and the molding holding time is 60±5S; the heating temperature of the heating tube 23 is 130±5℃.

[0024] In some embodiments, Figure 2 As shown, in order to ensure the molding quality, the pressure-maintaining mechanism 7 includes a pressure-maintaining buckle arranged on one side of the fixed mold 21 or the movable mold 22, and a buckle seat arranged on the corresponding side of the other. The use of the pressure-maintaining buckle and the buckle seat, when the driving mechanism 3 drives the movable mold 21 to move to a predetermined position to close the mold with the fixed mold 21, can be converted to the cooperation of the pressure-maintaining buckle and the buckle seat to maintain the pressure of the movable mold 22 toward the fixed mold 21, without the need for secondary intervention of the electrical or hydraulic system, which is conducive to reducing the operating cost of the clamping mechanism 2 and can ensure that the trunk cover is fully formed and solidified.

[0025] In some embodiments, Figure 2 As shown, in order to accurately close the mold of the mold clamping mechanism 2, a guide module 8 is provided on the side of one of the fixed mold 21 or the movable mold 22, and a guide mold groove matched with the guide module 8 is provided on the side of the other, and the guide module 8 and the pressure holding mechanism 7 are located on different sides of the mold clamping mechanism 2. In this embodiment, the guide module 8 and the guide mold groove cooperate with each other to guide the movable mold 22 and the fixed mold 21 to accurately align during the mold closing process to avoid molding defects caused by misalignment. At the same time, the guide module 8 and the pressure holding mechanism 7 are placed on two sides of the mold clamping mechanism 2 to avoid affecting the normal operation of each other and facilitate the realization of their respective functions.

[0026] In some embodiments, Figure 4 and Figure 5As shown, in order to achieve a uniform heating effect, the heating pipe 23 is arranged in an S shape inside the fixed mold 21 and the movable mold 22, and the two ends of the S-shaped heating pipe 23 are respectively an oil return port and an oil outlet. Two copper quick connectors 231 are arranged on the same side of the fixed mold 21 and the movable mold 22, and the oil return port and the oil outlet are respectively connected to the external heating system through the copper quick connector 231 for cyclic heating. In this way, the heating pipe 23 arranged in an S shape can cover a wider area inside the fixed mold 21 and the movable mold 22, and achieve a more uniform heating distribution. The oil return port and the oil outlet of the heating pipe 23 are located on the same side of the fixed mold 21 and the movable mold 22 and are respectively connected to the external heating system through the copper quick connector 231, forming a closed-loop system for cyclic heating. At the same time, the copper quick connector 231 can be used to achieve a quick and effective connection, which is convenient for the construction of the heating oil pipeline. It should be noted that the "S shape" mentioned in this embodiment refers to the "S shape" arrangement of the heat medium flow path inside the heating pipe 23.

[0027] In some embodiments, Figure 3 As shown, the fixed mold 21 and the movable mold 22 are detachably connected to a plurality of balancing blocks 9 and mounting grooves adapted to the balancing blocks 9. The bottom of the balancing block 9 is integrally formed with a plug-in column 91, and the bottom surface of the mounting groove is provided with a plug-in hole adapted to the plug-in column 91. In this way, by plugging the plug-in column 91 into the plug-in hole, a plurality of balancing blocks 9 can be installed according to actual needs, which can effectively balance the weight of the entire mold, avoid unbalanced pressure caused by the center of gravity offset, and ensure the quality of the molded product.

[0028] In some embodiments, Figure 3 As shown, the outer surfaces of the fixed mold 21 and the movable mold 22 are provided with heat insulation boards 10. The heat insulation boards 10 can effectively reduce the influence of the external temperature on the internal temperature of the mold, and also reduce the heat loss, so as to better control the temperature stability inside the mold and ensure the stable progress of the molding process.

[0029] In some embodiments, Figure 1As shown, in order to improve the operating efficiency of the clamping mechanism, a heating oven 12 and a glue spraying mechanism 13 are also included. The heating oven 12 is used to soften the trunk cover and / or the cover coating layer, and the glue spraying mechanism 13 is used to spray glue on the coating surface of the trunk cover. In this embodiment, similar to the previous work process, after the trunk cover is prepared, the trunk cover and the cover coating layer need to be compounded. The introduction of the heating oven 12 can realize the pretreatment and softening of the cover coating material. The heating oven 12 is used to soften the cover coating layer, and then put it into the clamping mechanism 2 together with the trunk cover. At this time, the glue spraying mechanism 13 works to spray PUR glue on the coating surface of the trunk cover to ensure that the cover and the coating layer are firmly compounded into one after the fixed mold 21 and the movable mold 22 are hot-pressed, thereby realizing that the pre-baking, glue spraying and hot pressing of the cover coating material can be carried out continuously on the same equipment without intermediate transfer, saving transportation time and shortening the overall production cycle.

[0030] The luggage compartment cover foaming hot-closing tooling provided in the present embodiment, by heating the double molds and utilizing a pressure-holding mechanism and other designs, not only achieves the foaming and curing of the material, but also ensures the efficiency and consistency of producing high-quality cover plates. Furthermore, while meeting the requirements of light weight, shock resistance, sound insulation and other properties, it simplifies the production process and completes the production of the required cover plates in one step, thereby reducing manual labor and effectively reducing production costs.
