The heating assembly 4 includes a connecting frame 401, a fixing member 402, a combination frame 403, and an electric heating tube 404. The bottom of the connecting frame 401 is connected to the fixing member 402, and the lower end of the fixing member 402 is connected to the combination frame 403. The bottom of the combination frame 403 is vertically mounted with the electric heating tube 404. The upper mold assembly 3 and the lower mold assembly 6 both have insertion holes that match the surface structure of the electric heating tube 404. The lower mold assembly 6 is fixedly mounted in the middle of the interior of a base 101. Group 3 includes a mold base 301, an upper mold 302, a connecting pile 303, a first guide 304, and a second guide 305. The upper mold 302 is installed inside the mold base 301, and the connecting pile 303 is horizontally installed in the upper middle section of the left and right sides of the mold base 301. The first guide 304 is horizontally arranged on the side of the connecting pile 303 near the front end of the mold base 301, and the second guide 305 is symmetrically installed on the left and right sides of the rear side of the mold base 301. When the upper mold group 3 is structurally connected to the lower mold group 6 under the operation of the first hydraulic cylinder 2 connected on both sides, the heating component 4 connected to it will move vertically downward under the structural extension and retraction adjustment of the second hydraulic cylinder 5, and insert the multiple sets of electric heating tubes 404 arranged in the array at the bottom of the combination frame 403 into the connected upper mold group 3 and lower mold group 6, and rapidly heat the upper mold 302 and lower mold 603 inside.

[0026] like Figures 1 to 5As shown, the mold frame 1 includes a base 101, support columns 102, a top plate 103, a first guide column 104, and a second guide column 105. Support columns 102 are vertically installed at the four opposite corners of the base 101, and the top of the support columns 102 is connected to the top plate 103. The first guide column 104 and the second guide column 105 are vertically installed on the left, right, and rear sides between the base 101 and the top plate 103, respectively. The first guide column 104 and the second guide column 105 have identical structures. The second guide column 105 is symmetrically and vertically installed on the rear facade between the base 101 and the top plate 103. The second guide member 305 has identical structures to the first guide member 304, and the first guide column 104 and the second guide column 105 vertically penetrate the first guide member 304 and the second guide member 305, respectively. The bottom end of the first hydraulic cylinder 2 is connected and fixed to one end of the connecting pile 303. The lower mold... Group 6 includes a buffer seat 601, a limiting pin 602, and a lower mold 603. The limiting pins 602 are vertically installed at the four opposite corners of the top of the buffer seat 601, and the lower mold 603 is installed at the upper part of the interior of the buffer seat 601.

[0028] As the upper module 3 moves down and docks with the lower module 6, the limiting pins 602 at the four opposite corners of the buffer seat 601 will eventually be inserted into the matching insertion holes at the four opposite corners of the bottom of the mold seat 301, thereby ensuring the stability of the upper module 3 and the lower module 6 after docking.

[0029] Then the injection molding material supply device is connected with the injection port in the middle of the top of the upper mold group 3 through the pipeline, then the second hydraulic cylinder 5 and the heating assembly 4 connected at the bottom are started, under the structure pushing of the second hydraulic cylinder 5 at the top of the connection frame 401, the whole heating assembly 4 will vertically move down, and multiple groups of electric heating pipes 404 vertically inserted into the upper mold group 3 and the lower mold group 6 after connection are arranged in the lower array of the combined frame 403, under the operation of the multiple groups of electric heating pipes 404, the inside of the upper mold 302 and the lower mold 603 will be heated to the appropriate temperature, so as to ensure that the molten injection molding part keeps enough fluidity in the cavity of the upper mold 302 and the lower mold 603, so as to prevent the situation of injection molding not in place or local shrinkage of the injection molding part caused by temperature difference.

[0030] Until the injection of the injection molding material is completed, then under the operation of the second hydraulic cylinder 5, the heating assembly 4 is lifted and the structure is reset, so as to cool and form the injection molding part.
