Their main function is to provide a sealing effect between the inside and outside of the car compartment, ensuring the sealing, comfort and safety of the vehicle. Automobile sealing strips are often produced through injection molding.

[0003] Chinese patent authorization announcement number: CN 213260830 U provides an injection mold for an automobile sealing strip. When in use, the first cylinder is started to drive the upper mold base to move downward, so as to close the mold with the lower mold base. At the same time, the guide sleeve will move on the fixed column to ensure the accuracy of the mold closing. By setting a stripper plate, after the sealing strip is formed, the second cylinder is started to drive the stripper plate to move upward, so that the stripper rod pushes the sealing strip upward, which is convenient for demolding the sealing strip.

[0004] In actual use of the prior art, since the raw material of the automobile sealing strip has a certain viscosity after being melted, it is easy to get blocked or stagnant in the flow channel when entering the mold cavity through the injection port, resulting in difficulty in the stable entry of the raw material, which brings inconvenience to the operator's loading operation. Therefore, an automobile sealing strip injection mold that is easy to load is proposed. Utility Model Content

[0039] See also Figure 1 , Figure 2 and Figure 5 The inner cavity of the fixed mold 104 is provided with a demoulding mechanism 4, including an ejector plate 401 movably connected to the inner cavity of the fixed mold 104, the lower surface of the ejector plate 401 is fixedly connected to a telescopic rod 2 402, and the inner cavity of the fixed mold 104 is fixedly connected to an air inlet pipe 404;

[0041] Furthermore, gas is injected into the fixed mold 104 through the air inlet pipe 404, and the gas pushes the ejector plate 401 to move upward and away from the fixed mold and pushes the cooled and formed automobile sealing strip to move upward. At this time, the gas enters between the fixed mold 104 and the automobile sealing strip from the staggered gap, thereby realizing rapid demolding of the automobile sealing strip.

[0042] Working principle: During the use of the device, the operator places the operating table 1 through the supporting legs 101 at the designated place where the automobile sealing strip is injected through the mold, and drives the mold 105 to move downward by starting the electric push rod 201 to closely abut against the fixed mold 104 to form a whole injection mold, and drives the U-shaped limiting plate 206 to move vertically inward with the cooperation of the telescopic rod 205 through the elastic force of the spring 207 to surround the outer surface of the fixed plate 204, so that the fixed plate 204 and the movable plate 203 are limited and connected together. At this time, the fixed mold 104 and the movable mold 105 are fixedly connected together. To ensure the stability during injection molding and avoid displacement affecting the injection molding effect, the molten automobile sealing strip raw material is then injected into the inner cavity of the fixed mold 104 and the movable mold 105 through the injection port 202. During the injection molding, the motor 301 is started to drive the cam 302 to rotate continuously to push the push plate 2 303 to move upward and make up and down reciprocating motion through the cooperation of the spring 305, driving the ball rod 304 to continuously impact the bottom of the fixed mold 104, so that the fixed mold 104 and the movable mold 105 produce continuous vibration. The vibration can accelerate the downward flow of the viscous liquid, reduce stagnation and blockage, and make the liquid smooth. The flow of the body is smoother, avoiding the blockage or stagnation of the automobile sealing strip raw material in the flow channel, which makes it difficult to enter stably, causing inconvenience to the operator's loading operation, and improving the convenience of the device loading. After the injection molding is cooled, the operator manually moves the U-shaped limit plate 206 outward and drives the movable mold 105 to move upward and away from the fixed mold 104 through the electric push rod 201, and then injects gas into the fixed mold 104 through the air inlet pipe 404. The gas will push the ejector plate 401 to move upward and away from the fixed mold and push the cooled and formed automobile sealing strip to move upward. At this time, the gas enters the fixed mold 104 from the staggered gap. After the demoulding is completed, the operator pulls up the push rod 210 to drive the push plate 211 to move upward to squeeze the spring 207 and then rotates the connecting plate 209 to drive the push rod 210 and the push plate 211 to rotate above the injection port 202. At this time, the push rod 210 is released and the push rod 210 and the push plate 211 are driven downward by the elastic force of the spring 207 to scrape off the residual automobile sealing strip material inside the injection port 202 to avoid impurities remaining in the flow channel, hindering the flow of raw materials and affecting feeding.
