[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0025] Embodiment 1:

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The metal material injection molding device for a mirror rod includes a substrate 1, and also includes: two injection mold plates 101, which are symmetrically slidably connected to the substrate 1, wherein the injection mold plates 101 are provided with an injection cavity 102, and the injection mold plates 101 are provided with a liquid injection hole 103 connected to the injection cavity 102; a driving unit, which is arranged on the substrate 1 and is used to drive the two injection mold plates 101 to move synchronously in opposite directions; a fixing frame 105, which is fixedly connected to the injection mold plates 101, wherein the fixing frame A sleeve 2 is symmetrically fixedly connected to 105, a piston disc 201 is slidably connected inside the sleeve 2, and a tooth plate 203 is fixedly connected to the piston disc 201; an elastic component is arranged in the sleeve 2 and is located between the piston disc 201 and the inner wall of the sleeve 2; a rotating shaft 204 is rotatably connected to the fixed frame 105, wherein a half gear 205 used in conjunction with the tooth plate 203 is fixedly connected to the rotating shaft 204; a driving mechanism is arranged on the fixed frame 105 and is used to drive the rotating shaft 204 to rotate.

[0027] The driving mechanism includes a motor 206 . The motor 206 is fixedly mounted on the fixing frame 105 . The rotating shaft 204 is fixedly connected to an output end of the motor 206 .

[0028] The driving part comprises a cylinder 104 , which is symmetrically fixedly mounted on the base plate 1 , and the two injection mold plates 101 are fixedly connected to the output ends of the two cylinders 104 , respectively.

[0029] The elastic component includes a spring 202 , one end of which is fixedly connected to the piston disc 201 , and the other end of which is fixedly connected to the inner wall of the sleeve 2 .

[0030] When the mirror rod is injection molded by the injection molding device, firstly, the cylinder 104 drives the fixing frame 105 to drive the two injection molding templates 101 to move synchronously toward each other until the two injection molding templates 101 are tightly fitted, and then the material is injected into the injection molding cavity 102 through the injection hole 103. When the material is submerged in the injection molding cavity 102, the feeding can be stopped, and then the motor 206 is started. The motor 206 drives the rotating shaft 204 to drive the half gear 205 to rotate. When the half gear 205 is engaged with the tooth plate 203 during the rotation process, the half gear 205 can drive the tooth plate 203 to rotate. 03 drives the piston plate 201 to slide into the sleeve 2 and compresses the spring 202. Then, when the half gear 205 separates from the tooth plate 203, the compressed spring 202 generates thrust to push the piston plate 201 to move out of the sleeve 2. At the same time, the piston plate 201 drives the tooth plate 203 to move to the side close to the injection mold 101, so that when the tooth plate 203 and the injection mold 101 are against each other, they knock the injection mold 101 to generate vibration, and then the air in the material is discharged from the injection cavity 102 through the injection hole 103, so as to improve the quality of the mirror rod during cooling and molding;

[0031] Based on the above, after the mirror rod is cooled and formed, the injection molding plate 101 is struck to generate vibration, which helps to separate the mirror rod from the injection molding cavity 102 , thereby facilitating the staff to take the mirror rod out of the injection molding cavity 102 .

[0032] When the mirror rod is cooled and formed and needs to be taken out from the injection cavity 102 , the cylinder 104 drives the fixing frame 105 to drive the two injection mold plates 101 to move synchronously in opposite directions until the two injection mold plates 101 are separated, so that the mirror rod can be taken out from the injection cavity 102 .

[0033] Embodiment 2:

[0034] Reference Figure 3 , Figure 6 , Figure 7 and Figure 8 The metal material injection molding device of the mirror rod is basically the same as that of the embodiment 1. Furthermore, a cooling cavity 302 is opened inside the injection molding template 101, and the sleeve 2 is fixedly connected with a conduit 1 3 and a conduit 2 301, and the end of the conduit 2 301 away from the sleeve 2 is fixedly connected with the liquid inlet end of the cooling cavity 302, and the liquid outlet end of the cooling cavity 302 is fixedly connected with a reflux pipe 303;

[0035] It should be noted that before using the injection molding device to perform injection molding on the mirror rod, it is first necessary to connect the end of the conduit 3 away from the sleeve 2 to the external liquid storage tank, and connect the end of the return pipe 303 away from the cooling chamber 302 to the external liquid storage tank;

[0036] It should be noted that both the conduit 1 3 and the return pipe 303 are made of stretchable and shrinkable hoses, so that the conduit 1 3 and the return pipe 303 are easily connected to the external liquid storage tank.

[0037] Based on Example 1, during the injection molding of the mirror rod, when the piston disc 201 moves outside the sleeve 2, the coolant in the liquid storage tank is sucked through the conduit 1 3 and transported into the sleeve 2 for temporary storage. Then, when the piston disc 201 moves into the sleeve 2, the coolant temporarily stored in the sleeve 2 is squeezed by the piston disc 201 and transported into the cooling cavity 302 through the conduit 2 301. Then, when the cooling cavity 302 is filled with coolant, the coolant flows back into the liquid storage tank through the reflux pipe 303, thereby pre-cooling the material in the injection cavity 102, thereby accelerating the subsequent cooling and molding of the mirror rod. One-way valves are provided on the conduit 1 3, the conduit 2 301, and the reflux pipe 303.

[0038] Embodiment 3:

[0039] Reference Figure 1 , Figure 2 The metal material injection molding device of the mirror rod is basically the same as that of Example 1. Furthermore, the upper and lower ends of the substrate 1 are symmetrically fixedly connected with the support guide rod 4, and the two injection molding templates 101 are slidably connected to the support guide rod 4;

[0040] When the cylinder 104 drives the fixed frame 105 to drive the two injection molds 101 to move synchronously in opposite directions or toward each other, the support guide rod 4 is set to play a limiting and guiding role for the two injection molds 101 sliding on the substrate 1, thereby improving the stability of the two injection molds 101 when sliding.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
