A lower mold 104 is provided inside the mounting groove 102b. The lower mold 104 is clearance-fitted with the mounting plate 102. A cavity 104c is opened on the upper side of the middle position of the lower mold 104. A connecting block 105 is provided below the lower mold 104 for connecting multiple T-shaped rods 106. A T-shaped hole 104a is opened below the cavity 104c corresponding to the position of the lower mold 104. The T-shaped rods 106 are located in the T-shaped hole 104a and move axially. The T-shaped rods 106 fixed to the connecting block 105 are provided inside the T-shaped hole 104a. The end of the T-shaped rod 106 with a larger diameter faces upward. Specifically, the upper wall of the lower mold 104 is provided with an upper mold 103, the lower wall of the upper mold 103 is fitted with the upper wall of the lower mold 104, and an injection hole 103a is provided at the position of the upper mold 103 corresponding to the cavity 104c. The injection material passes through the injection hole 103a and enters the cavity 104c for injection molding. The upper wall of the upper mold 103 is fixed with a U-shaped mounting bracket 101a. The upper wall of the mounting bracket 101a is fixed with an electric push rod 101 for driving the mounting bracket 101a to move, thereby driving the upper mold 103 to move. The upper end of the electric push rod 101 is fixed with an L-shaped fixing bracket 102a that is fixed to the mounting plate 102. Countersunk holes 104b are provided at the four corners of the lower mold 104 to provide installation space for bolts 107. Bolts 107 that are threaded to the mounting plate 102 are provided inside the countersunk holes 104b. Hex socket head cap screws 107 can be used. The horizontal plane of the top of the bolt 107 is lower than the horizontal plane of the upper wall of the lower mold 104 to prevent it from hindering the smooth fitting of the upper mold 103 and the lower mold 104. The operation process of this embodiment is as follows: First, control the electric push rod 101 to retract and drive the mounting bracket 101a and the upper mold 103 to rise to a suitable position. At this time, loosen the bolt 107 and remove the bolt 107. Then remove the lower mold 104. Place the lower mold 104 with the required cavity 104c in the mounting groove 102b. Then, operate the bolt 107 to enter the countersunk hole 104b. Finally, tighten the bolt 107 to complete the replacement of the lower mold 104 and realize the injection molding of edge buckles of different specifications and sizes.

[0025] Example 2 Please see Figure 1 , Figure 5 and Figure 6 This is the second embodiment of the present utility model. This embodiment is based on the previous embodiment, but differs from the first embodiment in that: a material discharge mechanism 2 is provided below the mold body 1. The material discharge mechanism 2 includes a positioning box 201 that is clearance-fitted to the outside of the connecting block 105. An electric telescopic rod 202 is fixedly provided on the lower wall of the positioning box 201, which is used to drive the positioning box 201 to move and drive the connecting block 105 to move, and finally make the T-shaped rod 106 move. A rectangular plate 204 is fixedly provided at the lower end of the electric telescopic rod 202. Specifically, a positioning hole 105a is provided in the middle of the connecting block 105, and U-shaped side plates 201a are symmetrically fixed on the left and right side walls of the positioning box 201. An insertion rod 203 is provided in a gap fit on the outer side wall of the side plate 201a. With the above configuration, when the insertion rod 203 is inserted into the positioning hole 105a, the movable end of the electric telescopic rod 202 moves and drives the positioning box 201 to move, thereby driving the connecting block 105 to move. The outer end of the insertion rod 203 is fixed with a frustum-shaped pinch block 203b, and the inner end of the insertion rod 203 is located inside the positioning hole 105a. The left and right side walls of the positioning box 201 are provided with magnetic sheets 203a fixed to the insertion rod 203. The magnetic sheets 203a are magnetic and therefore have magnetic attraction. With the above configuration, by operating the pinch block 203b to move, the corresponding insertion rod 203 moves, so that the insertion rod 203 is inserted into or removed from the positioning hole 105a. Connecting rods 204a are fixedly installed at the four corners of the upper wall of the rectangular plate 204. The upper ends of the connecting rods 204a are fixedly connected to the mounting plate 102. Screws 205a are threadedly connected at the four corners of the rectangular plate 204. A base plate 205 is fixedly installed at the lower end of the screws 205a. Anti-slip pads 205b are fixedly installed on the lower wall of the base plate 205. The anti-slip pads 205b are in contact with the placement platform. With the above configuration, by operating the base plate 205 to rotate, the corresponding screws 205a will rotate until all anti-slip pads 205b are in contact with the placement platform, so that the edge buckle assembly mold can be stably placed on the placement platform. Furthermore, both the side plate 201a and the positioning box 201 are made of magnetically attractive materials. Before replacing the lower mold 104, it is necessary to operate the pinch block 203b to move away from the positioning box 201 so that the insertion rod 203 is disengaged from the positioning hole 105a. After the lower mold 104 is installed, in order to improve the connection stability between the positioning box 201 and the connecting block 105, it is necessary to operate the pinch block 203b to move towards the positioning box 201 until the magnetic sheet 203a and the positioning box 201 are in a magnetically attracted state. At this time, the inner end of the insertion rod 203 is located in the positioning hole 105a. The operation process of this embodiment is as follows: When removing the edge buckle inside the cavity 104c, firstly, the electric push rod 101 is retracted to drive the upper mold 103 to a suitable height. Then, the electric telescopic rod 202 is extended to drive the positioning box 201 and the connecting block 105 to move upward. Finally, the T-shaped rod 106 is moved upward in the T-shaped hole 104a, pushing the edge buckle inside the cavity 104c out of the cavity 104c, so that the operator can easily remove the edge buckle.

[0026] It should be noted that the electric push rod 101 and electric telescopic rod 202 used in this side buckle assembly mold are electrically connected to the controller via conductive wires, and the controller is electrically connected to an external power source via conductive wires. Furthermore, the electric push rod 101, electric telescopic rod 202, and controller are all existing technologies, and their models are not limited here.
