The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] The first embodiment of this application is as follows:

[0021] Please see Figures 1 to 4 ,in Figure 1 This is a schematic diagram of the overall structure of a hot-pressing mold for automotive door armrests. Figure 2 This is a front view of the overall hot-pressing mold for car door armrests. Figure 3 This is a schematic diagram of the driver component. Figure 4 This is a front sectional view of the pressure plate. This utility model provides a hot-press forming mold for automotive door panel armrests: including a mold body 101, a fixed pressure plate 102, a pressure plate 103, and an ejection device. The ejection device includes an ejection block 104, a heat dissipation plate 105, a driving assembly, and a connecting assembly. The heat dissipation plate 105 has heat dissipation holes 106. The driving assembly includes a driving motor 107 and a driving rod 108. The connecting assembly includes a connecting rod 109 and a sliding plate 110. A fan 111 is provided on the mold body 101. The aforementioned solution solves the problem that after hot-pressing automotive door panel armrests, it is inconvenient to remove them from the pressure plate 103, leading to reduced work efficiency and inconvenience. It is understood that the aforementioned solution can facilitate the removal of automotive door panel armrests from the pressure plate 103 after hot-pressing, improving work efficiency and ease of use. It can also facilitate the cooling of the mold after forming.

[0022] In this specific embodiment, the fixed pressure plate 102 is fixedly connected to the mold body 101 and located on one side of the mold body 101. The fixed pressure plate 103 is fixedly connected to the fixed pressure plate 102 and located on one side of the fixed pressure plate 102. The fixed pressure plate 102 is provided inside the mold body 101. The fixed pressure plate 103 is provided on the upper surface of the fixed pressure plate 102. The fixed pressure plate 103 is provided with a material holding groove inside. The material holding groove and the fixed pressure plate 103 are integrally formed. A movable pressure plate is provided directly above the fixed pressure plate 102. A moving pressure plate is provided on the lower surface of the movable pressure plate. The moving pressure plate and the fixed pressure plate 103 cooperate with each other to perform hot pressing molding of the car door panel armrest. All of the above are prior art, so this application does not describe them in detail.

[0023] The ejector block 104 is slidably connected to the pressure plate 103 and located on one side of the pressure plate 103. The heat sink 105 is detachably connected to the mold body 101 and located on one side of the mold body 101. The drive assembly is disposed on the mold body 101, and the connecting assembly is disposed on the ejector block 104. The heat dissipation hole 106 penetrates the heat sink 105. The ejector block 104 is located at the center of the pressure plate 103. When the ejector block 104 is not in operation, the ejector block 104 and the interior of the pressure plate 103 are on the same horizontal plane. A placement groove is provided at the bottom front side of the mold body 101. The drive assembly and the connecting assembly are both located in the placement groove. The heat sink 105 is disposed at the opening of the placement groove. The heat dissipation hole 106 is provided through the surface of the heat sink 105 and communicates with the placement groove. The heat dissipation plate 105 allows for heat dissipation and cooling of the drive assembly inside the mold body 101. The drive assembly works in conjunction with the connecting assembly. When the drive assembly is activated, it drives the connecting assembly to move the ejector block 104 upwards, thereby ejecting the molded car door panel armrest upwards and completing demolding. This process is simple. After the car door panel armrest is hot-pressed, the ejector block 104 is positioned at the center of the pressure plate 103. The drive assembly and connecting assembly are located inside the mold body 101. Activating the drive assembly drives the connecting assembly upwards, causing the connecting assembly to move the ejector block 104 upwards, thus ejecting the car door panel armrest upwards. This facilitates demolding, improves work efficiency, and is convenient to use.

[0024] Secondly, the drive motor 107 is fixedly connected to the mold body 101 and located on one side of the mold body 101; the top end of the drive rod 108 is rotatably connected to the mold body 101, the bottom end of the drive rod 108 is fixedly connected to the output end of the drive motor 107, the drive motor 107 is fixed to the bottom of the placement slot of the mold body 101, the output end of the drive motor 107 is fixed with the drive rod 108, and the top end of the drive rod 108 rotates at the top of the placement slot of the mold body 101 through a bearing, so that when the drive motor 107 starts, it drives the drive rod 108 to rotate synchronously.

[0025] Meanwhile, the connecting rod 109 is fixedly connected to the ejector block 104 and slidably connected to the fixed pressure plate 102; the sliding plate 110 is fixedly connected to the connecting rod 109 and threadedly connected to the drive rod 108; and the sliding plate 110 is slidably connected to the mold body 101, the sliding plate 110 is located in the placement groove of the mold body 101, the two ends of the sliding plate 110 abut against the two ends of the placement groove, and the sliding plate 110 is penetrated by the drive rod 108, so that when the drive rod 108 rotates, the sliding plate 110... The sliding plate 110 moves vertically within the placement groove of the mold body 101 under the threaded drive of the rotating drive rod 108. The connecting rods 109 are fixed on both sides of the upper surface of the sliding plate 110. Both connecting rods 109 pass through the fixed pressure plate 102 and are fixed together with the lower sides of the ejector block 104. When the sliding plate 110 moves, the connecting rods 109 drive the ejector block 104 to move, thereby facilitating the ejection of the mold through the ejector block 104. This makes the operation simple and improves work efficiency.

[0026] In addition, the blower 111 is fixedly connected to the mold body 101 and is located on one side of the mold body 101. The blower 111 is provided on the right side of the outer surface of the mold body 101. The air outlet of the blower 111 faces the pressure plate 103. When the blower 111 is started, it can generate wind force in the direction of the pressure plate 103, so that after the car door armrest is hot-pressed, the air flow rate on the surface of the car door armrest can be accelerated, so that the mold can be formed as soon as possible, thereby improving work efficiency and facilitating the subsequent ejection of the mold.

[0027] When using the hot pressing mold for automotive door panel armrests according to this embodiment, after the automotive door panel armrests are hot-pressed, an ejector block 104 is set at the center of the pressure plate 103, and a drive assembly and a connecting assembly are set inside the mold body 101. The drive assembly is activated, and the drive assembly drives the connecting assembly to move upward, so that the connecting assembly drives the ejector block 104 to move upward, thereby ejecting the automotive door panel armrests upward through the ejector block 104, making it easy to demold, improving work efficiency, and making it convenient to use.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
