[0002] Plastic injection molding technology developed from the late 19th century to the early 20th century based on the die-casting principle and is one of the most commonly used methods in current plastic processing. The working principle of an injection molding machine is to inject the plastic in a molten state (i.e., viscous flow state) that has been plasticized well into a closed mold cavity by means of the thrust of a screw (or plunger), and obtain the product after curing and shaping.
[0003] In the patent document with the publication number CN219806402U, a liquid silicone injection molding machine is disclosed. A blowing device is arranged above the device, and after injection molding, the debris generated by the injection molding assembly can be blown off through the blowing device. A collecting device is arranged below the injection molding assembly, and the fallen debris will be collected uniformly by the collecting device, which is convenient for processing and can effectively avoid the situation that the debris flies out of the machine and falls on the ground and is difficult to clean.
[0004] However, for this liquid silicone injection molding machine in the case of long-term placement, due to the decrease in temperature, the liquid silicone stored in the liquid silicone injection storage tank may solidify due to long-term placement, resulting in the device being unable to start normally.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] As Figures 1-5 shown, a liquid silicone rubber injection molding machine includes a silicone rubber storage barrel 1 and an injection molding pipe 2. The injection molding pipe 2 is fixedly connected to the side of the silicone rubber storage barrel 1. An injection molding device is installed inside the silicone rubber storage barrel 1. The injection molding device includes a storage unit and an injection molding unit. The storage unit is installed inside the silicone rubber storage barrel 1, and the injection molding unit is installed inside the injection molding pipe 2;
[0026] The storage unit includes a first motor 101, which is fixedly connected above the silicone storage barrel 1. The bottom of the output shaft of the first motor 101 is fixedly connected with a rotating shaft 102. The outer surface of the rotating shaft 102 is fixedly connected with a heating tube assembly 103. The outer surface of the heating tube assembly 103 is fixedly connected with stirring blades 104. A heating chamber 105 is opened inside the silicone storage barrel 1. An electric heating elbow 106 is fixedly connected inside the heating chamber 105. A circulating water pipe 107 is fixedly connected to the side of the silicone storage barrel 1. A circulating water pump 108 is fixedly installed on the outer surface of the circulating water pipe 107. A water filling port 109 is fixedly connected to the side of the silicone storage barrel 1. Thus, by installing the storage unit, the liquid silicone fluid to be injection-molded is further placed inside the silicone storage barrel 1. Further, water is filled into the heating chamber 105 through the water filling port 109. Further, by starting the first motor 101, the heating tube assembly 103, and the electric heating elbow 106, the circulating water pipe 107 heats the water inside the heating chamber 105. At the same time, in cooperation with the heating tube assembly 103, it can ensure that the silicone fluid inside the silicone storage barrel 1 is in a high-temperature environment. Further, in cooperation with the continuous rotation of the stirring blades 104, the silicone fluid inside the silicone storage barrel 1 is in a flowing state, which can prevent the silicone fluid from solidifying, facilitating the subsequent use of the device and further improving the practicability of the device.
[0027] The injection-molding unit includes a transportation pipe 201, which is fixedly connected to the bottom of the silicone storage barrel 1. The other end of the transportation pipe 201 is fixedly connected to an injection-molding barrel 202. The bottom of the injection-molding barrel 202 is fixedly connected with a bracket 204. A second motor 203 is fixedly connected to the side of the injection-molding barrel 202. The output shaft of the second motor 203 is fixedly connected with a central shaft 205. The outer surface of the central shaft 205 is fixedly connected with a transportation auger 206. An injection port 207 is opened at one end of the injection-molding barrel 202 away from the second motor 203. By installing the injection-molding unit, the liquid silicone fluid inside the silicone storage barrel 1 enters the injection-molding barrel 202 through the transportation pipe 201. Further, by starting the second motor 203, the second motor 203 drives the central shaft 205 to rotate. Further, by the rotation of the central shaft 205, the transportation auger 206 starts to move, discharging the liquid silicone fluid through the injection port 207, enabling the subsequent injection-molding process.
[0028] The heating tube assembly 103 is composed of a heating inner cavity 1031 and an electric heating tube 1032. The heating inner cavity 1031 is opened inside the heating tube assembly 103. The electric heating tube 1032 is fixedly connected inside the heating inner cavity 1031. The heating inner cavity 1031 is filled with water. Thus, when the device is started, the electric heating tube 1032 heats the water inside the heating inner cavity 1031, further cooperating with the stirring blades 104 to heat and stir the liquid silicone fluid inside the silicone storage barrel 1.
[0029] On one side of the stirring paddle 104 away from the heating pipe assembly 103, a scraper is fixedly connected. The scraper contacts the inner wall of the silicone storage barrel 1. Thus, the motor 101 drives the stirring paddle 104 to rotate, further enabling the scraper to scrape the inner wall of the silicone storage barrel 1, thereby preventing liquid silicone from adhering to the inner wall of the silicone storage barrel 1.
[0030] A control valve is installed inside the transport pipe 201, and a control handle is connected to the outer surface of the control valve. Thus, by rotating the control handle and further cooperating with the control valve, the flow rate of the liquid silicone entering the injection barrel 202 from the transport pipe 201 can be controlled.
[0031] Support feet 110 are fixedly connected to the outer surface of the silicone storage barrel 1, thereby providing support for the silicone storage barrel 1 through the support feet 110.
[0032] It should be specifically noted that the specific installation methods, circuit connection methods, and control methods of the motor 101 and the motor 203 used in the present utility model are all conventional designs, and the present utility model will not be elaborated in detail.
[0033] The working principle of the present utility model is as follows: Place the liquid silicone to be injection-molded inside the silicone storage barrel 1. Further, water is filled into the heating chamber 105 through the water filling port 109. Then, by starting the motor 101, the heating pipe assembly 103, and the electric heating elbow 106, the circulating water pipe 107 heats the water inside the heating chamber 105. At the same time, in cooperation with the heating pipe assembly 103, it can ensure that the silicone liquid inside the silicone storage barrel 1 is in a high-temperature environment. Further, in cooperation with the continuous rotation of the stirring paddle 104, the silicone liquid inside the silicone storage barrel 1 is in a flowing state. By rotating the control handle, the liquid silicone inside the silicone storage barrel 1 is transported from the transport pipe 201 to the inside of the injection barrel 202. By starting the motor 203, the motor 203 drives the central shaft 205 to rotate. Further, due to the rotation of the central shaft 205, the transport auger 206 starts to move, thereby discharging the liquid silicone through the injection port 207, and subsequent injection-molding processes can be carried out.
