Description

Technical Field

[0001] This utility model relates to the field of mold structure technology, specifically to an inner ejector mold structure for the production of medical device shells. Background Technology

[0002] Injection molds are key tools used in the injection molding process. They are used to inject molten plastic into the mold cavity, which then cools and solidifies to form plastic products of a specific shape.

[0003] Patent CN210910820U discloses a plastic mold ejection mechanism, including a first mounting chamber. A support block is located on one side of the bottom of the first mounting chamber. A motor compartment is located on the top of the support block. A second servo motor is located inside the motor compartment. A support rod is located at the middle position inside the first mounting chamber. The second mounting chamber is installed at the middle position of the support rod. The output end of the second servo motor extends into the interior of the second mounting chamber. A sleeve is installed at the output end of the second servo motor. Slides are evenly arranged on the outer side of the sleeve. Slide blocks are provided at the top and bottom of the slides to cooperate with them. This patented device, through the cooperation of the slides, sleeve, slide blocks, U-shaped connecting plate, connecting rod, second mounting chamber, second servo motor, and motor compartment, eliminates the need for manual mold removal, thereby improving mold removal efficiency.

[0004] As shown in the above technology, the medical device housing is a medical plastic product. In the production process, mainstream medical injection molding production lines have adopted three-axis servo robots. However, the finished product is generally embedded inside the mold, and its surface is attached to the inner surface of the mold, making it difficult to remove. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an inner ejector mold structure for the production of medical device shells, which solves the problem that finished products are generally embedded inside the mold, with their surface adhering to the inner surface of the mold, making them difficult to remove.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an inner ejector mold structure for the production of medical device housings, comprising:

[0007] The working base plate has reinforcing ribs at its bottom and a stationary module fixedly connected to its top. The stationary module has a placement groove at its bottom and a moving module movably connected to its top. Both the moving module and the stationary module have embedding grooves on their surfaces.

[0008] A separation assembly, the bottom of which is fixedly connected to one side of the inner wall of the placement groove, is used to quickly eject and separate the injection-molded medical device shell;

[0009] A limiting component, one side of which is fixedly connected to one side of the working base plate, is used to press the modules together during the injection molding process of the medical device shell.

[0010] Preferably, the separation assembly includes a support plate fixedly connected to one side of the working base plate, and a separation telescopic rod is fixedly connected to the top of the support plate.

[0011] Preferably, a folding plate is fixedly connected to the top of the telescopic rod, a synchronization plate is fixedly connected to the bottom of one side of the folding plate, a spring is fixedly connected to the top of the synchronization plate, and the top of the spring is fixedly connected to the top of the inner wall of the placement groove.

[0012] Preferably, a connector rod is fixedly connected to one side of the top of the synchronization plate, and a sliding cover plate is fixedly connected to the top of the connector rod.

[0013] Preferably, the limiting component includes a side panel fixedly connected to one side of the working base plate, and a separation plate fixedly connected to the top of the side panel.

[0014] Preferably, a horizontal telescopic rod is fixedly connected to one side of the separation plate, a vertical plate is fixedly connected to one end of the horizontal telescopic rod, and a connector plate is fixedly connected to one side of the vertical plate.

[0015] This invention provides an inner ejector mold structure for the production of medical device housings. Compared with the prior art, it has the following advantages:

[0016] 1. This inner ejector mold structure for the production of medical device shells utilizes a separation component. The self-extension of the separation telescopic rod directly drives the synchronous plate, connector rod, and sliding cover plate. The sliding cover plate directly ejects the formed medical device shell from the mold, facilitating subsequent removal by a robotic arm. Furthermore, the spring ensures timely and stable reset of the device, solving the problem that finished products are generally embedded inside the mold, with their surface adhering to the inner surface of the mold, making them difficult to remove.

[0017] 2. This inner ejector mold structure for the production of medical device shells utilizes a limiting component and a vertical plate on one side of the horizontal telescopic rod to effectively combine the static module and the moving module, preventing them from separating during operation. The separation plate allows for free adjustment of the working timing, preventing the static module and the moving module from remaining in an extended working state even when they are completely separated.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides two technical solutions:

[0026] Example 1: An inner ejector mold structure for manufacturing medical device housings, comprising:

[0027] The working base plate 1 has a reinforcing rib at the bottom and a stationary module 2 fixedly connected to the top. The bottom of the stationary module 2 has a placement groove 3 and the top of the stationary module 2 is movably connected to a moving module 4. Both sides of the surfaces of the moving module 4 and the stationary module 2 have an embedding groove 5.

[0028] Separation component 6, the bottom of separation component 6 is fixedly connected to one side of the inner wall of placement groove 3, separation component 6 is used to quickly eject and separate the medical device shell after injection molding;

[0029] The limiting component 7 is fixedly connected to one side of the working base plate 1. The limiting component 7 is used to press the modules together during the injection molding process of the medical device shell. With the setting of the separation component 6, the separation telescopic rod 62 can extend by itself to directly drive the synchronization plate 64, the connector rod 66 and the sliding cover plate 67. The molded medical device shell can be directly ejected from the mold through the sliding cover plate 67, which is convenient for the subsequent robotic arm to take it out. The spring 65 can ensure that the device can be reset in a timely and stable manner.

[0030] Example 2 differs from Example 1 primarily in that, for the inner ejection mold structure used in the production of medical device casings, the separation component 6 includes a support plate 61 fixedly connected to one side of the working base plate 1. A separation telescopic rod 62 is fixedly connected to the top of the support plate 61. A folding plate 63 is fixedly connected to the top of the separation telescopic rod 62. A synchronization plate 64 is fixedly connected to the bottom of one side of the folding plate 63. A spring 65 is fixedly connected to the top of the synchronization plate 64. The spring 65 requires the use of a damper. The top of the spring 65 is fixedly connected to the top of the inner wall of the placement groove 3. A connecting rod 66 is fixedly connected to one side of the top of the synchronization plate 64. The connecting rod 66 is located in the middle of the spring 65, and the top of the connecting rod 66... A sliding cover plate 67 is fixedly connected. The limiting component 7 includes a side panel 71 fixedly connected to one side of the working base plate 1. A separation plate 72 is fixedly connected to the top of the side panel 71. A horizontal telescopic rod 73 is fixedly connected to one side of the separation plate 72. A vertical plate 74 is fixedly connected to one end of the horizontal telescopic rod 73. A connector plate 75 is fixedly connected to one side of the vertical plate 74. By using the setting of the limiting component 7, the static module 2 and the moving module 4 can be effectively combined through the vertical plate 74 on one side of the horizontal telescopic rod 73, so as to prevent them from separating during operation. The working time can be freely adjusted through the separation plate 72 to prevent the static module 2 and the moving module 4 from remaining in an extended working state when they are completely separated.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] During operation, the moving module 4 is lowered to contact the top of the stationary module 2. At this time, the separation plate 72 and the transverse telescopic rod 73 on one side of the extended side panel 71 extend, causing the connecting plate 75 to engage with the embedded groove 5. The stationary module 2 and the moving module 4 are stably combined. After being stably placed, molten plastic is injected into the moving module 4 through the top and enters the molding position through the flow channel. After it cools and forms, the separation plate 72 shrinks and the connecting plate 75 separates from the embedded groove 5. Then, the separation telescopic rod 62 on the top of the rising support plate 61 moves the connecting rod 66 upward through the folding plate 63 and the synchronous plate 64. Then, the sliding cover plate 67 moves upward to push the formed blank out of the mold. Then, the separation telescopic rod 62 resets, causing the connecting rod 66 to reset, and the spring 65 resets at the same time. When the device has finished working, the device is restored.
