Injection molding products have many varieties, shapes can be from simple to complex, size can be from large to small, suitable for mass production of complex shaped products. Injection molding mold is the tool of injection molding production. When injection molding, the heated and melted plastic is injected into the mold cavity, and the shaped product is obtained after cooling and solidification.

[0003] Some products will cause certain pressure impact on the mold during injection molding production due to the expansion of materials or factors such as bubbles. Although it can be discharged by setting exhaust holes and other means, sometimes the pressure cannot be completely removed due to the position and number of discharge holes. Therefore, a fixed connection structure is usually provided on the shell of the injection molding mold to fix it during injection molding. However, for small injection molding products or low value injection molding products, the installation and disassembly of the connection structure will reduce the production efficiency and increase the cost of the mold.

It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0021] The purpose of this invention is to address the shortcomings of existing technologies by providing a pressure stabilizing device for injection molds.

[0022] Example 1

[0023] This embodiment provides a pressure stabilizing device for injection molds, referring to... Figure 1 As shown, the system includes a support frame 1, a pressure plate assembly 2, a sliding assembly 3, cylinders 4, a control box 5, and a support frame 6. There are two pressure plate assemblies 2, located at the upper and lower parts of the inner side of the support frame 1, respectively. Two sets of sliding assemblies 3 are fixed to the left and right sides of the support frame 1, respectively, allowing the pressure plate assembly 2 to move vertically up and down. Two cylinders 4 are vertically fixed to the top and bottom of the support frame 1, respectively, with the front of each cylinder connected to the pressure plate assembly 2. The support frame 6 is fixed to the bottom of the support frame 1. The control box 5 is fixed to the support frame 6 and is used to control the movement of the cylinders 4. The control box 5 contains a cylinder control valve, a PLC controller, and other auxiliary devices. The components and working principle of the control box 5 are not described in detail in this embodiment. The bottom of the support frame 6 is detachably equipped with four feet 7 for better support. Specifically, each foot 7 has a threaded hole at its top center and the bottom center of the support frame 6, with a threaded post 8 installed in the threaded hole.

[0024] Reference Figures 2-3As shown, the support frame 1 includes a vertical rod 11, a top frame 12, and a support plate 13. There are two support plates 13, located at the top and bottom of the vertical rod 11 respectively. The outer sides of the two support plates 13 are connected and fixed by four vertical rods 11. The top frame 12 is fixed to the top of the support plate 13 located at the top.

[0025] Reference Figures 2-4 As shown in this embodiment, each pressure plate assembly 2 includes two pressure plates 21. The pressure plate 21 at the bottom of the upper pressure plate assembly 2 and the pressure plate 21 at the top of the lower pressure plate assembly 2 are provided with a connecting seat 22 in the center. The other two pressure plates 21 are provided with a pressure plate through hole 23 in the center. The driving end of the cylinder 4 is connected to the connecting seat 22.

[0026] Reference Figures 3-4 As shown, the sliding assembly 3 includes a sliding column seat 31, a slider 32, and a sliding column 33. In each set of sliding assemblies 3, two sliding column seats 31 are vertically fixed to the outside of two support plates 13 located at the top and bottom, respectively. The two ends of the sliding column 33 are fixed in the two sliding column seats 31, respectively. Four sliders 32 are slidably fitted onto a sliding column 33. The sliders 32 are fixed to the outside of the pressure plate 21. Each pressure plate 21 uses two sliders 32 on its left and right sides to slide on the sliding column 33 to achieve vertical up and down movement. In this embodiment, the vertical rod 11 is an L-shaped vertical rod. Therefore, when the pressure plate 21 moves vertically up and down, its four corners are located inside the four L-shaped vertical rods, which can further maintain stability.

[0027] Reference Figures 3-4 As shown, the sliding assembly 3 also includes eight threaded rods 35 and sixteen threaded rod seats 34. Threaded rod seats 34 are fixed to the outer sides of the support plate 13 and the pressure plate 21, as well as between two adjacent pressure plates 21. A threaded rod 35 is inserted between every two threaded rod seats 34. The bottom end of the threaded rod 35 is connected to a nut through a threaded engagement. By setting the threaded rod 35 and the nut, the support plate 13 and the pressure plate 21, as well as between two adjacent pressure plates 21, can be separated, facilitating the placement of the injection mold assembly. It eliminates the need to manually separate the support plate 13 from the pressure plate 21 and adjacent pressure plates 21, making operation easier and improving the placement efficiency of the injection mold.

[0028] This utility model discloses a pressure stabilizing device for injection molds. In use, multiple small injection molds with completed injection cavities are transferred in batches onto pressure plates 21. The cylinder 4 is activated, and its drive end propels the lower pressure plates 21 downwards vertically. Each pressure plate 21 utilizes two sliders 32 on its left and right sides to slide on sliding pillars 33, maintaining stable movement and applying pressure to multiple injection molds in batches to meet the pressure requirements of injection molding. This method eliminates the need for mold shell connection and fixing structures on the outer shell of the injection mold, thus simplifying the mold structure and reducing costs. It also avoids the need to install and disassemble the connection and fixing structures for each injection mold during production, thereby improving production efficiency.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
