DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-7 The utility model provides a technical solution: a mold for a rear shell of an automobile that is easy to replace the mold, including a base 1, a condenser 2, a lower mold 3, a mounting block 4, a connecting mechanism 5, an auxiliary block 6, a connecting bolt 7, a connecting column 8, a movable rod 9, a fixed pressing plate 10, a top bracket 11, a stamping column 12, a top seat 13, a fixing rod 14, an upper mold 15, a side plate 16, a fixing bolt 17 and a fixing sleeve 18.

[0032] When using the automobile rear shell mold that is easy to replace the mold, Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, firstly, the corresponding lower mold 3 is placed on the upper end of the base 1 according to the production requirements, and combined with the setting of the connecting mechanism 5, the connecting mechanism 5 is symmetrically arranged on the left and right sides of the upper end of the base 1, and the connecting mechanism 5 includes an auxiliary block 6 fixedly connected to the side of the upper end of the base 1, a connecting bolt 7 for adjustment, a connecting column 8 rotatably connected to the upper end of the connecting bolt 7, a movable rod 9 for connection, and a fixed pressing plate 10 fixedly connected to the side of the movable rod 9. First, the connecting column 8 is rotated, and the connecting column 8 drives the movable rod 9 and the fixed pressing plate 10 to be placed above the base 1, and then the movable rod 9 is pulled to the side close to the lower mold 3, and the movable rod 9 slides between the connecting column 8, so that the movable rod 9 drives the connecting column 8 to be placed above the mounting block 4, and then the connecting bolt 7 threadedly connected to the middle part of the auxiliary block 6 is rotated, and the connecting bolt 7 rotates with the connecting column 8, and the connecting bolt 7 drives the movable rod 9 and the fixed pressing plate 10 to move downward through the connecting column 8, thereby driving the fixed pressing plate 10 to engage with the mounting block 4, and the lower mold 3 is fixedly installed on the upper end of the base 1;

[0033] like Figure 3 and Figure 7As shown, the upper mold 15 is fitted on the lower end of the top seat 13, and then the fixing bolt 17 is inserted into the side plate 16, and the fixing bolt 17 is plugged into the left and right ends of the top seat 13, and then the fixing sleeve 18 threadedly connected to the outer surface of the fixing bolt 17 is rotated so that the fixing sleeve 18 is fitted on the left and right ends of the top seat 13, so that the upper mold 15 is installed at the lower end of the top seat 13. Through the above operation, the mold can be disassembled and replaced very conveniently. After the mold is installed, the raw materials for the production of the rear shell of the automobile are placed on the lower mold 3, and the stamping column 12 is started to drive the top seat 13 to move downward, so that the top seat 13 drives the upper mold 15 to move downward to stamp the raw materials on the lower mold 3. At the same time, the top seat 13 drives the fixing rod 14 and the top bracket 11 to slide up and down during the lifting and moving process, so that it can play a certain limiting role on the upper mold 15, and prevent the upper mold 15 from offsetting and causing errors during the long-term lifting and moving process;

[0034] In addition, if Figure 1 and Figure 2 As shown, a condenser 2 is embedded in the upper end of the base 1, and the condenser 2 is connected to the cooling device at the front end. Coolant is provided inside the condenser 2. The condenser 2 and the lower mold 3 are fitted together. When the temperature of the mold rises during long-term use, the mold can be cooled by the condenser 2. Moreover, the condenser 2 is curved, which increases the contact area with the lower mold 3, and the actual heat dissipation effect is good.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
