[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-Figure 3The utility model provides an embodiment: an injection mold for a car welcome lamp capable of controlling the material flow rate, comprising a base 1, a support column 5 is fixedly connected to the top of the base 1, a fixed plate 8 is fixedly connected to the top of the support column 5, the base 1, the support column 5 and the fixed plate 8 are prior art, and are used for injection molding of a car welcome lamp, which is a prior art and will not be explained in detail here, an adjusting mechanism 3 is arranged at the center of the fixed plate 8, and the material flow rate is adjusted by the adjusting mechanism 3, an electric telescopic rod 7 is fixedly arranged at the bottom end of the fixed plate 8, and an upper mold 4 is fixedly connected to the bottom end of the electric telescopic rod 7, and the upper mold 4 is driven to move by the electric telescopic rod 7 to achieve the purpose of extrusion injection molding, and the electric telescopic rod 7 is a prior art and will not be explained in detail here, a water cooling mechanism 6 is arranged on the inner wall of the base 1; the water cooling mechanism 6 is used to achieve the purpose of rapid cooling, and the water cooling mechanism 6 comprises a water inlet pipe 601, and the water inlet pipe 601 The outer wall is fixedly connected to the inner wall of the base 1, and cooling water is discharged to the inner wall of the base 1 through the water inlet pipe 601. A water storage tank 608 is provided on the inner wall of the base 1. A fixed column 603 is fixedly connected to the inner wall of the base 1. The fixed column 603 plays a supporting and connecting role, and three groups are provided. The right end fixed column 603 is located between the two groups of fixed columns 603 on the left end. A magnetic block 606 is fixedly connected to the inner wall of the bottom end of the fixed column 603. The outer wall of the magnetic block 606 is elastically connected to a magnet 607 through a connecting spring 605. The bottom end of the magnet 607 is the positive pole, and the top end of the magnetic block 606 is the positive pole. Through the principle of like charges repelling each other between the magnetic block 606 and the magnet 607, a buffering effect can be achieved. The top end of the magnet 607 is fixedly connected to a movable column 602, and the two have the same motion trajectory. The top end of the movable column 602 is fixedly connected to the lower mold 2. An adjusting mechanism 3 is provided at the center of the fixed plate 8, and the purpose of adjusting the flow rate is achieved through the adjusting mechanism 3.

[0034] Reference Figure 1-Figure 3The outer wall of the fixed column 603 is rotatably connected with a connecting rod 604, and the top of the connecting rod 604 is rotatably connected to the outer wall of the movable column 602. When the connecting rod 604 rotates, the connecting rod 604 as a whole will bend, and a certain impact force will be dispersed during bending, thereby enhancing the buffering effect. The inner wall of the upper mold 4 is slidably connected to the outer wall of the supporting column 5, and the sliding of the two plays a guiding role to prevent the mold from being offset after long-term use. The outer wall of the upper mold 4 is plugged into the inner wall of the lower mold 2, and the injection molding operation is performed when the two are plugged in. The left end of the water inlet pipe 601 is connected to the water storage tank 608. The inner walls are connected, the outer wall of the lower mold 2 is in contact with the inner wall of the base 1, and cooling water is discharged into the inner wall of the water storage tank 608 through the water inlet pipe 601. When the base 1 is in contact with the lower mold 2, the cooling water cools the mold through heat transfer. One end of the connecting spring 605 is fixedly connected to the top of the magnetic block 606, and the other end of the connecting spring 605 is fixedly connected to the bottom end of the magnet 607. The outer walls of the movable column 602 and the magnet 607 are both slidably connected to the inner wall of the fixed column 603. The elasticity of the connecting spring 605 makes the movable column 602 have a reset buffering effect.

[0035] Reference Figure 1 and Figure 4 The adjusting mechanism 3 includes an injection molding tube 306, the outer wall of which is fixedly connected to the center of the fixed plate 8, and the injection molding effect is achieved through the injection molding tube 306. The inner wall of the bottom end of the injection molding tube 306 is fixedly connected to the positioning plate 304, and the inner wall of the positioning plate 304 is rotatably connected to the rotating tube 301. When the rotating tube 301 rotates, it will not separate from the inner wall of the positioning plate 304. The outer wall of the rotating tube 301 is fixedly connected to the rotating plate 302. The rotating plate 302 and the positioning plate 304 are both semicircular, and the diameter of the rotating plate 302 is larger than the positioning plate 304. The bottom end of the rotating plate 302 contacts the top of the positioning plate 304. The contact between the two enables the positioning plate 304 to have a certain supporting force on the rotating plate 302. The inner wall of the rotating plate 302 is elastically connected to the ball 303 through the return spring 307.

[0036] Reference Figure 4-Figure 5 One end of the reset spring 307 is fixedly connected to the inner wall of the rotating plate 302, and the other end of the reset spring 307 is fixedly connected to the outer wall of the ball 303. The outer wall of the ball 303 is slidably connected to the rotating plate 302. The elasticity of the reset spring 307 enables the ball 303 to have reset and limit functions. The inner wall of the injection molding tube 306 is provided with a ball hole 305, and the outer wall of the ball 303 is plugged into the inner wall of the ball hole 305. When the two groups are plugged in, when the rotating tube 301 is not rotated manually, it is in a fixed state.

[0037] Working principle: When the relevant personnel need to perform injection molding on the automobile welcome lamp mold, they first rotate the rotating tube 301 to drive the rotating plate 302 to rotate. When the rotating plate 302 rotates, it will drive the ball 303 to move. When the ball 303 moves, it is squeezed by the inner wall of the injection tube 306 and moves toward the inner wall of the rotating plate 302, so that the overlapping area between the rotating plate 302 and the positioning plate 304 is different, so that the material flow rate can be changed. The operation is simple and convenient. When the rotating plate 302 is adjusted, the elasticity of the reset spring 307 resets the ball 303 and plugs it into the ball hole 305 to complete the fixation.

[0038] Starting the electric telescopic rod 7 causes the electric telescopic rod 7 to drive the upper mold 4 to move downward, thereby connecting the upper mold 4 with the lower mold 2. At this time, the injection molding operation can be performed through the injection molding tube 306. After the injection molding is completed, starting the electric telescopic rod 7 causes the upper mold 4 to move together with the lower mold 2, thereby contacting the inner wall of the base 1. The inner wall of the water storage tank 608 of the base 1 is provided with cooling water, thereby increasing the contact area between the entire mold and the water, thereby achieving a better cooling effect. When the mold 2 moves downward, it drives the extrusion connecting spring 605 to be compressed, and the connecting rod 604 will bend. Through the reaction force of the connecting spring 605, a buffering effect is achieved. At the same time, the bending of the connecting rod 604 disperses part of the force. At the same time, when the movable column 602 moves to a certain position, the surfaces that the magnetic block 606 and the magnet 607 are about to contact repel each other with the same polarity, thereby enhancing the buffering effect.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
