Description

Technical Field

[0001] This application relates to the field of molds, and more specifically, to a tire mold that facilitates material removal. Background Technology

[0002] Currently, tires are one of the most important components of a car. Their main functions include: supporting the entire weight of the vehicle and bearing the load; transmitting traction and braking torque and ensuring the adhesion between the wheels and the road surface; reducing and absorbing vibrations and impacts during driving, preventing severe vibrations and premature damage to car parts, adapting to the high-speed performance of the vehicle and reducing noise during driving, and ensuring driving safety, handling stability, comfort, and fuel economy. Molds are required when processing tires.

[0003] Publication No. CN119502275A; Publication Date: February 25, 2025; This application discloses a tire mold that is easy to demold and its usage method, relating to the field of mold technology.

[0010] In a preferred embodiment of this utility model, a top plate is fixed to the top of the support frame, and the fixed end of the electric push rod is installed on the surface of the top plate.

[0011] In a preferred embodiment of this utility model, a sliding sleeve is provided through the surface of the top plate, a limiting rod is slidably inserted into the sliding sleeve, the lower end of the limiting rod is fixedly connected to the support plate A, and at least two sliding sleeves are provided.

[0012] In a preferred embodiment of this utility model, a positioning pin is fixed to the lower end face of the upper mold, and a positioning hole is opened on the upper end face of the lower mold. The positioning pin is inserted into the positioning hole. There are two positioning pins and two corresponding positioning holes. The two positioning holes are respectively opened on the surface of the left half mold and the right half mold.

[0013] In a preferred embodiment of this utility model, a positioning post is fixed to the side wall of the left half mold, and a positioning groove is provided on the side wall of the right half mold. The positioning post and the positioning groove are inserted into each other, and one side of the left half mold and one side of the right half mold are sealed together.

The lower end of the return spring is fixed to the lower end of the pull rod, and the upper end of the return spring is fixed to the support frame.

[0017] Beneficial Effects: This application provides a tire mold that facilitates material removal. An electric push rod drives the upper mold upwards, causing it to separate from the lower mold after moving a certain distance. The separated upper mold continues to move upwards, causing the support plate A to contact the upper end of the lifting frame, which in turn drives the lifting frame to slide upwards. The lower end of the lifting frame drives the support plate B upwards. During the upward movement of support plate B, the left and right connecting rods are activated, causing the left connecting rod to push the left slide block along the slide rail, and the right connecting rod to push the right slide block along the slide rail. This causes the left and right halves of the mold to separate, exposing the forming material inside the mold assembly. A lifting mechanism is then used to lift the blank, facilitating the removal of the forming material. By using a single drive device (electric push rod) in conjunction with the lifting frame, the material removal action can be completed, simplifying the equipment structure and operation steps, reducing equipment and maintenance costs, and improving work efficiency.

[0040] The working principle of this tire mold that facilitates material removal is as follows: During use, the electric push rod 110 drives the upper mold 310 to move upward, causing the upper mold 310 to move a certain distance and separate from the lower mold 330. After separation, the upper mold 310 continues to move upward, causing the support plate A111 to abut against the upper end of the lifting frame 130, thereby causing the lifting frame 130 to slide upward. The lower end of the lifting frame 130 drives the support plate B150 to move upward. During the upward movement of the support plate B150, it drives the left connecting rod 1711 and the right connecting rod 1731, causing the left connecting rod 1711 to push the left slide block. 171 slides along slide rail 170, and right connecting rod 1731 pushes right slide block 173 to slide along slide rail 170, thereby causing left half mold 331 and right half mold 333 to separate from each other, so that the forming material in mold assembly 300 is exposed. The blank is lifted by the set lifting mechanism 500, which facilitates the unloading of the forming material. By using a drive device electric push rod 110 in conjunction with lifting frame 130, the unloading action can be completed, simplifying the equipment structure and operation steps, reducing equipment cost and maintenance cost, and improving work efficiency.
