[0020] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0021] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0022] like Figures 1 to 4 As shown, a mold replacement assembly for a double-head injection molding machine provided by an embodiment of the utility model comprises a processing table 1, an injection molding machine 2, an upper mold 3 and a lower mold 4. The injection molding machine 2 is fixedly connected to the right side of the top of the processing table 1, the upper mold 3 is arranged at the bottom of the injection molding machine 2, and the upper mold 3 is arranged at the top of the processing table 1. The positions of the upper mold 3 and the lower mold 4 correspond to each other. Two splicing blocks 5 are fixedly connected to the front and rear sides of the lower mold 4. A slot 6 is provided on one side of the top surface of the processing table 1 corresponding to the splicing block 5, and the splicing block 5 is plugged and connected to the inside of the slot 6. A concave block 7 is fixedly connected to the front and rear sides of the upper mold 3, and a socket 8 is provided at the notch of the concave block 7. A connecting block 9 is fixedly connected to the front and rear sides of the injection molding machine 2, and the connecting block 9 is plugged and connected to the notch of the concave block 7. A cavity 10 is provided inside the connecting block 9, and a positioning mechanism 11 is provided inside the cavity 10. An adjusting mechanism 12 used in conjunction with the positioning mechanism 11 is provided inside the cavity 10.

[0023] refer to Figure 2 The positioning mechanism 11 includes a load-bearing column 1101, two first compression springs 1102, two T blocks 1103 and two inclined blocks 1104. The load-bearing column 1101 is fixedly connected to the middle part of the inner wall of the cavity 10. The two first compression springs 1102 are respectively fixedly connected to the left and right sides of the load-bearing column 1101. The two T blocks 1103 are respectively fixedly connected to the side of the two first compression springs 1102 away from the load-bearing column 1101, and one end of the T block 1103 penetrates and extends to the inside of the socket 8 on the surface of the recessed block 7. The two inclined blocks 1104 are respectively fixedly connected to the tops of the two T blocks 1103. The two inclined blocks 1104 are used in conjunction with the adjustment mechanism 12.

[0024] By adopting the above solution, the positioning mechanism 11 is provided, and the concave block 7 can be fixed by the connecting block 9 , so that the upper mold 3 is fixed to the bottom of the injection molding machine 2 .

[0025] refer to Figure 2 The adjustment mechanism 12 includes a pressing rod 1201, an H-block 1202 and two pushing columns 1203. The pressing rod 1201 is fixedly connected to the middle part of the H-block 1202, and the top of the pressing rod 1201 passes through and extends out of the surface of the connecting block 9. The two pushing columns 1203 are respectively fixedly connected to the notches on the left and right sides of the H-block 1202. The two pushing columns 1203 are both located on the side away from the two inclined blocks 1104, and the surface of the pushing column 1203 is in contact with the inclined surface of the inclined block 1104.

[0026] By adopting the above solution, the upper mold 3 can be disassembled by providing the adjustment mechanism 12, and then replaced with a new mold as needed.

[0027] refer to Figure 2 A limiting rod 13 is provided at the bottom of the T block 1103 , and both ends of the limiting rod 13 are fixedly connected to the inner wall of the cavity 10 and the surface of the load-bearing column 1101 respectively, and the T block 1103 is slidably connected to the surface of the limiting rod 13 .

[0028] By adopting the above solution, the limiting rod 13 is provided to limit the movement of the T block 1103, thereby preventing the T block 1103 from deviating during movement.

[0029] refer to Figure 2 The two pressing rods 1201 pass through the top of one side of the connecting block 9 and are fixedly connected to a grip rod 14. The bottom of the grip rod 14 is fixedly connected to a second compression spring 15, and the bottom of the second compression spring 15 is fixedly connected to the top of the connecting block 9. The second compression spring 15 is sleeved on the surface of the pressing rod 1201.

[0030] By adopting the above solution, by providing the gripping rod 14 and the second compression spring 15 , the two connection blocks 9 on one side can be operated simultaneously, and then the gripping rod 14 can be driven to rebound by the rebound force of the second compression spring 15 .

[0031] refer to Figure 1 and Figure 4 , both the front and rear sides of the upper mold 3 are fixedly connected with plug-in blocks 16, and the position of the plug-in blocks 16 corresponds to the splicing block 5.

[0032] By adopting the above solution, the upper mold 3 and the lower mold 4 can be assembled by providing the plug-in block 16, thereby avoiding deviation of the molds during splicing.

[0033] refer to Figure 2 The top of the load-bearing column 1101 is fixedly connected with a magnetic block 17, and the magnetic block 17 is magnetically connected to the H block 1202.

[0034] The above solution is adopted: by setting the magnetic block 17, it can be magnetically connected with the H block 1202 when it moves to the top of the load-bearing column 1101, so as to avoid the H block 1202 from rebounding due to lack of pressure.

[0035] The working principle of this utility model:

[0036] By pressing the gripping rod 14 downward, the gripping rod 14 drives the pressing columns on both sides of the bottom to move downward, and the pressing columns drive the H block 1202 and the two pushing columns 1203 to move downward when moving, and the two pushing columns 1203 squeeze the inclined surfaces of the two inclined blocks 1104 when moving, thereby driving the two to move toward each other. When moving, the two inclined blocks 1104 drive the T block 1103 to move toward each other, and squeeze the first compression spring 1102 at the same time. At this time, the T block 1103 is away from the socket 8 on the surface of the recessed block 7. After the H block 1202 is magnetically connected to the magnetic block 17 on the top of the load-bearing column 1101, the gripping rod 14 on the other side can be pressed, and then the upper mold 3 can be disassembled, and then the lower mold 4 can be disassembled according to the upper mold 3, thereby completing the replacement of the upper mold 3 and the lower mold 4.

[0037] In summary: the mold replacement assembly for double-head injection molding machine processing solves the problem that when processing the umbrella ribs through the mold, the mold needs to be replaced according to different size requirements, so as to complete the processing of the umbrella ribs. However, the operation is too cumbersome when replacing the mold, thereby reducing the processing efficiency of the umbrella ribs.
