Description

Technical Field

[0001] This utility model relates to the field of door panel armrest processing technology, specifically to a door panel armrest foaming mold. Background Technology

[0002] Door panel armrest foaming molds typically refer to polyurethane self-skinning foaming molds used for automotive door interior armrests. The mold cavity is CNC machined according to the three-dimensional curved surface of the armrest. During operation, a pre-placed ABS / PC armrest skeleton is positioned in the upper mold. After mold closing, high-pressure mixed polyurethane material is injected into the cavity. It foams, expands, and matures at a set mold temperature, causing the PU self-skinning foam to bond integrally with the skeleton. Upon mold opening, a door panel armrest with a micro-dense skin on the surface and a soft, elastic core is obtained. This mold is widely used in the production of automotive interior parts to ensure precise dimensions, a smooth surface, and a comfortable feel. Traditional door panel armrest foaming molds mostly use mechanical venting structures, driven by servo motors. The lag in action response makes it difficult to match the high-speed, high-pressure foaming rhythm, affecting the efficiency of door panel armrest foaming operations and failing to meet the high-efficiency and stable requirements of automated production lines. Utility Model Content

[0003] The purpose of this utility model is to provide a door panel armrest foaming mold to solve the problem mentioned in the background art that the traditional door panel armrest foaming molds are mostly mechanical exhaust structures. The mechanical structure is driven by a servo motor, which results in a lag in action response, making it difficult to match the high-speed and high-pressure foaming rhythm, affecting the efficiency of door panel armrest foaming operations, and making it difficult to meet the high efficiency and stability requirements of automated production lines.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a door panel armrest foaming mold, comprising a base plate, a lower mold above the base plate, a sealing rubber ring at the outer edge of the upper surface of the base plate, a limiting boss on the upper surface of the base plate and inside the sealing rubber ring, a cavity on the lower surface of the lower mold corresponding to the limiting boss, an actuating gas pipe connected to one side wall of the lower mold and the cavity, a limiting rod penetrating between the base plate and the lower mold and inside the sealing rubber ring, a limiting top plate at the upper end of the limiting rod, and a cavity on the upper surface of the lower mold.

[0005] Preferably, the upper surface of the lower mold includes a protruding surface, a recessed surface, and a planar surface, the cavity is disposed between the protruding surface, the recessed surface, and the planar surface, and the upper surface of the lower mold is provided with a guide groove and a fixing component on the outside of the cavity.

[0006] Preferably, the fixing component includes a groove formed on the upper surface of the lower mold. The groove has a square structure with rounded corners. Fixing blocks are threadedly connected to the interior of the groove in four directions. Fixing grooves are formed on the lower inner sides of the four fixing blocks.

[0007] Preferably, a receiving groove is provided on the upper surface of the lower mold at a position corresponding to the limiting top plate, and the limiting top plate is disposed inside the receiving groove.

[0008] Preferably, the lower end of the limiting rod is fixedly connected to the base plate by bolts, and the upper end of the limiting rod is fixedly connected to the limiting top plate by bolts.

[0009] Compared with existing technologies, the advantages of this utility model are as follows: It replaces the traditional mechanical exhaust structure of door panel armrest foaming molds, directly driving the cavity to sink and exhaust the lower mold through gas pipes, eliminating the need for servo motors and complex mechanical transmissions, significantly improving response speed. With the help of guide grooves and fixing components, it achieves precise positioning and rapid clamping. The limiting top plate is embedded in the storage groove, and the limiting rod is bolted to the bottom plate and the top plate, ensuring stable and reliable opening and closing. The overall structure is simplified and the movement is agile, effectively improving the efficiency of foaming operations. It perfectly adapts to the high-efficiency and stable production requirements of automated production lines, while reducing maintenance costs and failure rates, and has significant engineering practical value.

[0014] In use, a sealing rubber ring 3 is glued between the base plate 1 and the lower mold 2 to ensure the sealing between the base plate 1, the lower mold 2, and the sealing rubber ring 3 while providing a flexible connection between the lower mold 2 and the base plate 1. A limiting rod 7 is installed through the base plate 1 and the lower mold 2, with its lower end fixedly connected to the base plate 1. A limiting top plate 8 is installed at the upper end of the limiting rod 7 to limit the upper position of the lower mold 2. A limiting boss 4 is provided on the upper surface of the base plate 1, and a cavity 5 is provided on the lower surface of the lower mold 2. The upper surface of the limiting boss 4 abuts against... The lower mold 2 is positioned on the upper mold 2, thereby limiting its lower position. An external high-pressure gas source is connected to the cavity 5 through the actuating gas pipe 6. The external high-pressure gas source is input into the cavity 5 through the actuating gas pipe 6, ensuring that the lower mold 2 moves upward to the upper position of the limiting rod 7 and the limiting top plate 8, ensuring the fit precision between the cavity 9 of the lower mold 2 and the upper mold. The high-pressure gas inside the cavity 5 is extracted to the outside through the actuating gas pipe 6, so that the lower mold 2 moves downward to the lower position of the limiting boss 4 in a short time, ensuring rapid venting of the cavity 9.

[0015] The upper surface of the lower mold 2 includes a protruding surface 21, a recessed surface 22, and a planar surface 23. The cavity 9 is disposed between the protruding surface 21, the recessed surface 22, and the planar surface 23. The cavity 9 conforms to the foamed shape of the door panel armrest through the arrangement of the protruding surface 21, the recessed surface 22, and the planar surface 23. The upper surface of the lower mold 2 and the outer side of the cavity 9 are provided with a guide groove 10 and a fixing component 11. The guide groove 10 guides the upper mold, and the fixing component 11 fixes the upper mold and the lower mold 2.

[0016] The fixing component 11 includes a groove 1101 formed on the upper surface of the lower mold 2. The groove 1101 has a square structure with rounded corners. Fixing blocks 1102 are threadedly connected to the interior of the groove 1101 in four directions. Each of the four fixing blocks 1102 has a fixing groove 1103 at its lower inner side. The fixing pin of the upper mold is inserted into the fixing block 1102 inside the groove 1101 and is connected to the fixing groove 1103 to ensure the connection stability between the upper mold and the lower mold 2.

[0017] A receiving groove 12 is provided on the upper surface of the lower mold 2 at a position corresponding to the limiting top plate 8. The limiting top plate 8 is disposed inside the receiving groove 12, and the receiving groove 12 is used to store the limiting top plate 8 to avoid interference with the merging of the upper mold.

[0018] The lower end of the limiting rod 7 is fixedly connected to the base plate 1 by bolts, and the upper end of the limiting rod 7 is fixedly connected to the limiting top plate 8 by bolts, thereby limiting the upper position of the lower mold 2.
