[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1-3The utility model provides an embodiment of a hot press machine that is convenient for replacing molds, including a base 1, a hot pressing groove 2 is fixedly connected to the top surface of the base 1, a sliding rod 3 is slidably connected in the hot pressing groove 2, one end of the sliding rod 3 is fixedly connected to a fixed head 7, and the other end of the sliding rod 3 is fixedly connected to a fixed block 4, a spring 5 is sleeved on the sliding rod 3, support rods 8 are connected on both sides of the top surface of the base 1, the top of the support rod 8 is fixedly connected to a top plate 9, the bottom surface of the top plate 9 is fixedly connected to an electric push rod 10, the bottom end of the electric push rod 10 is fixedly connected to a connecting rod 11, the bottom end of the connecting rod 11 is fixedly connected to a hot pressing plate 12, a protective shell 14 is slidably connected to the connecting rod 11, and a spring 2 13 is fixedly connected to the top of the protective shell 14, and the spring 2 13 is sleeved on the connecting rod 11.

[0024] The electric push rod 10, the connecting rod 11 and the spring 2 13 are arranged in two groups in parallel to enhance the stability of the hot pressing plate 12 during transmission. The fixed block 4 is fixedly connected to the handle 6 on the side away from the slide rod 3, which improves the convenience of operation. The slide rod 3 and the spring 1 5 are arranged in three groups in parallel to improve the stability of the mold fixation. The slide rod 3, the fixed block 4, the spring 1 5, the handle 6 and the fixed head 7 are symmetrically arranged in two groups.

[0025] Working principle: When the mold of the hot press needs to be replaced, pull the handles 6 on both sides to make the fixed block 4 drive the slide rod 3 to slide on the hot pressing groove 2, and the slide rod 3 drives the fixed head 7 to move.
