[0002] Infrared thermometer temperature measurement is a thermometer with an ultra-low power consumption intelligent design. The non-contact infrared thermometer can determine the surface temperature by measuring the infrared energy radiated by the target surface. When processing and producing the infrared thermometer panel, an injection molding device is required for preparation.

[0003] For example, the publication number CN210880562U discloses a continuous injection molding device, including a workbench, an injection molding machine and an injection mold. The injection molding machine is fixedly installed on one side of the top of the workbench. The injection mold is composed of a fixed mold and a movable mold.

The movable mold is mutually attached and movably connected to the fixed mold, and the bottom of the movable mold is slidably connected to the upper surface of the workbench.

[0004] However, in the prior art, after continuous injection molding for a long time, there will be gaps when the two molds are closed, and the mechanical fatigue of the equipment also causes the mold closing to be not tight enough. In this case, the plastic material will remain in the mold and needs to be removed by re-opening the mold, which not only increases the complexity of the operation, but also exacerbates the wear of the mold and shortens the service life of the mold. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that the mold closing is not tight enough after continuous injection molding for a long time in the prior art, and to propose a continuous injection molding device for an infrared thermometer panel.

A first fixing plate is fixedly connected to the center of the top of the injection molding table, and a second fixing plate is fixedly connected to one side of the top of the injection molding table. An injection molding mechanism is installed between the first fixing plate and the second fixing plate, and extrusion mechanisms are installed on both sides of the second fixing plate;

[0007] The extrusion mechanism includes a second hydraulic cylinder. One side of the second hydraulic cylinder is fixedly connected to a support rod.

Specific embodiments

[0022] In order to more clearly understand the above objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0023] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1

[0025] As Figure 1 , Figure 3 and Figure 4 shown, the present utility model provides a continuous injection molding device for an infrared thermometer panel, including an injection molding table 1 and a conveyor 2 inside it. A first fixing plate 3 is fixedly connected to the center of the top of the injection molding table 1, and a second fixing plate 4 is fixedly connected to one side of the top of the injection molding table 1. An injection molding mechanism 7 is installed between the first fixing plate 3 and the second fixing plate 4, and extrusion mechanisms 6 are installed on both sides of the second fixing plate 4;

[0026] The extrusion mechanism 6 includes a second hydraulic cylinder 61. A support rod 62 is fixedly connected to one side of the second hydraulic cylinder 61. Two limiting rods 63 are rotatably connected to one end of the support rod 62. A hydraulic rod 69 is installed inside the second hydraulic cylinder 61. A lifting block 64 is fixedly connected to one end of the hydraulic rod 69. Push rods 65 are rotatably connected to both sides of the lifting block 64. One end of the push rod 65 is rotatably connected to the middle of one side of the limiting rod 63. A locking block 66 is rotatably connected to one end of the limiting rod 63. A locking port 68 is opened at one end of the locking block 66, and two linkage rods 67 are rotatably connected to one end of the locking block 66. One end of the linkage rod 67 is rotatably connected to the lifting block 64.

[0027] Specifically describe the specific settings and functions of this embodiment below. When the second hydraulic cylinder 61 starts to operate, the hydraulic force it releases drives the hydraulic rod 69 to move. As a key component for power transmission, the movement of the hydraulic rod 69 directly drives the start of the lifting block 64.

[0028] As the lifting block 64 moves, the movement of the lifting block 64 can be accurately converted into the corresponding movement of the locking block 66. At the same time, the lifting block 64 is also connected to the limiting rod 63 through the push rod 65. When the lifting block 64 moves, it will push the push rod 65, thereby causing the limiting rod 63 to start moving.

[0029] The movement form of the limiting rod 63 is rotational motion, and this rotation is centered on its connection point with the support rod 62. The support rod 62 plays a role in stabilizing the movement trajectory of the limiting rod 63, ensuring the smoothness and accuracy of its rotation. At the same time, the rotation of the limiting rod 63 cooperates with the movement of the linkage rod 67 to jointly control the movement trajectory and force of the locking block 66.

[0030] Under the coordinated action of the limiting rod 63 and the linkage rod 67, the locking block 66 gradually approaches the card slot 75. One end of the locking block 66 is designed with a locking port 68. When the locking block 66 reaches the appropriate position with the card slot 75, the locking port 68 will be precisely engaged with the card slot 75. Using the clamping force, the firmness after the first mold base 71 and the intermediate plate 72 are clamped together is further improved, realizing a precise and effective clamping action. The tightness of the clamping has been significantly improved, thus ensuring the stability and product quality during the injection molding process.

[0031] Embodiment Two

[0032] As Figure 1 and Figure 2 shown, the injection molding mechanism 7 includes a first mold base 71 and an intermediate plate 72. The first mold base 71 is fixedly connected to the side wall of the second fixed plate 4. Four fixed rods 76 are fixedly connected to the surface of the intermediate plate 72, and one end of the fixed rod 76 is fixedly connected to the first fixed plate 3. A second mold base 74 is installed on one side of the first mold base 71, and the second mold base 74 is slidably connected to the fixed rod 76. One end of the fixed rod 76 penetrates through the second mold base 74, and the fixed rod 76 is fixedly connected to the first mold base 71. A first hydraulic cylinder 5 is installed on one side of the first fixed plate 3. The output end of the first hydraulic cylinder 5 penetrates through the intermediate plate 72, and the output end of the first hydraulic cylinder 5 is fixedly connected to the second mold base 74. Card slots 75 are provided on both sides of the first mold base 71, and the card slots 75 are matched with the locking ports 68. A spring 73 is provided between the intermediate plate 72 and the second mold base 74, and the spring 73 is sleeved on the surface of the fixed rod 76.

[0033] The effect achieved by the entire embodiment is that when the first hydraulic cylinder 5 receives a start signal, it will start quickly and generate a powerful driving force. After being transmitted to the second mold base 74, it pushes the second mold base 74 to move smoothly on the surface of the fixed rod 76. The fixed rod 76 not only provides a stable track for the movement of the second mold base 74, but also ensures the accuracy and smoothness of the movement.

[0034] As the second mold base 74 moves, it gradually approaches the first mold base 71 and finally achieves a tight mold closing. The elasticity of the spring 73 can effectively compensate for the small deformations that may occur during the mold closing process, making the mold closing more tight and avoiding problems such as material leakage and flash during the injection molding process.

[0035] After the mold closing is completed, the injection molding machine performs continuous injection molding through the injection port on one side of the second mold base 74. The injection molding material is injected into the mold under high pressure to fill the entire mold cavity. During the injection molding process, the temperature and pressure of the mold need to be precisely controlled to ensure that the quality and performance of the injection molded parts meet the requirements.

[0036] When the injection molding is completed, the mold opens, and the injection molded part falls off the mold and lands above the conveyor 2. The conveyor 2 quickly and stably conveys the injection molded part to the next process for subsequent processing.

[0037] The usage method and working principle of this device: When performing continuous injection molding of the infrared thermometer panel, first use the driving force of the first hydraulic cylinder 5 to push the second mold base 74 to move smoothly on the surface of the fixed rod 76. As the second mold base 74 moves, it gradually approaches the first mold base 71 and finally achieves a tight mold closing. After the mold closing, continuous injection molding is carried out through the injection port on one side of the second mold base 74, and the molten plastic is injected into the mold to form the required injection molded part.

[0038] During the injection molding process, the elasticity of the spring 73 can act on the second mold base 74 to further increase the tightness of the mold closing between the second mold base 74 and the first mold base 71. At the same time, the spring 73 will slide on the surface of the fixed rod 76 during the movement, which not only plays a guiding role but also helps to ensure that the second mold base 74 and the first mold base 71 can be accurately mold closed.

[0039] To further improve the firmness of mold clamping, when the second hydraulic cylinder 61 starts to operate, it can control the movement of the hydraulic rod 69. The movement of the hydraulic rod 69 then drives the lifting block 64 to start moving. The lifting block 64 drives the locking block 66 to move through the linkage rod 67, and at the same time uses the push rod 65 to make the limit rod 63 start to rotate. The limit rod 63 rotates around the connection point with the support rod 62, and cooperates with the linkage rod 67 to jointly control the movement track of the locking block 66. As the locking block 66 moves, it gradually approaches the card slot 75, and engages with the card slot 75 using the locking port 68 at one end of it. This clamping force further enhances the firmness after the first mold base 71 and the intermediate plate 72 are clamped, ensuring that the mold clamping is more compact and reliable.

[0040] After the injection molding is completed, the injection molded parts will automatically fall off from the mold and fall above the conveyor 2 for transportation, so as to carry out subsequent processing or packaging. Subsequently, the entire continuous injection molding process will start again, realizing efficient and continuous production.

[0041] The above are only the preferred embodiments of the present invention, and are not limitations to the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
