The lower module 100 includes a mold cavity 101 arranged at its center. The clamping assembly 200 includes adjustment slots 201 provided in the lower module 100 on both sides of the mold cavity 101, and movable blocks 202 movably installed at the center of the adjustment slots 201. The first clamping plate 203 and the second clamping plate 204 are movably installed in the adjustment slots 201 on both sides of the movable block 202, respectively. The lower module 100 also has installation cavities 205 on both sides, and the installation cavities 205 are also fixedly installed with servo motors 206 for driving the movable block 202. , both ends of the inner side of the installation cavity 205 are also penetrated through the adjustment groove 201 to open a slide groove 207, the outer ends of the first clamping plate 203 and the second clamping plate 204 are also fixedly installed with a slide rod 208 through the slide groove 207, the clamping assembly 200 also includes a double-headed motor 209 fixedly installed at the center of the installation cavity 205, and a bidirectional threaded rod 210 fixedly installed at both ends of the double-headed motor 209, the bidirectional threaded rod 210 is matched and installed in the slide rod 208, the clamping assembly 200 also includes a stopper 211 fixedly installed at the outer end of the bidirectional threaded rod 210, and the clamping assembly 200 also includes a fixing frame 212 fixedly installed between the double-headed motor 209 and the lower module 100.

[0025] Specifically, the injection mold is a tool used for plastic injection molding. The mold movable block 202 is a component of the mold. It is separated from the main mold during molding and connected to the main mold by pins, dovetails, etc. The movable block 202 is mainly used to process the bosses of the parts that are not on the parting surface and the blocks that can be borrowed from each other. The movable blocks 202 movably installed on both sides of the mold cavity 101 in the lower module 100 can be conveniently rotated by the servo motor 206 after the first clamping plate 203 and the second clamping plate 204 on both sides are opened and closed along the adjustment groove 201. The movable block 202 can be adjusted by rotation to change the direction of the mold core inside the movable block 202. At the same time, the first clamping plate 203 and the second clamping plate 204 on both sides of the movable block 202 can also fix and clamp the movable block 202 on both sides after adjustment, so as to ensure its stability during use and avoid sliding problems due to extrusion during use. The sliding groove 207 provided on the inner side of the installation cavity 205 through the adjustment groove 201 mainly ensures the stability and positioning of the first clamping plate 203 and the second clamping plate 204 during opening and closing through the sliding rod 208, so as to ensure its horizontality before and after adjustment.

[0026] Embodiment 2:

[0027] Based on the first embodiment, Figure 2 As shown, the positioning assembly 300 includes a plurality of positioning holes 301 arranged on both sides of the movable block 202, and a plurality of positioning posts 302 arranged and fixedly installed on the inner sides of the first clamping plate 203 and the second clamping plate 204. The number of the positioning posts 302 is the same as the number of the positioning holes 301, and the positioning posts 302 match the positioning holes 301.

[0028] Specifically, the positioning columns 302 arranged and fixed at the inner ends of the first clamping plate 203 and the second clamping plate 204 in the lower module 100 can also quickly and accurately locate the position of the movable block 202 when the first clamping plate 203 and the second clamping plate 204 clamp the movable block 202, thereby ensuring the injection molding quality of the injection molded part in the mold cavity 101.

[0029] The working principle and use process of this utility model:

[0030] When the movable blocks 202 on both sides of the mold cavity 101 in the lower module 100 are adjusted in direction, the double-headed motor 209 in the mounting cavity 205 is first used to drive the slide bars 208 on both sides of the bidirectional threaded rod 210 to move outward along the slide groove 207, thereby driving the first clamping plate 203 and the second clamping plate 204 on both sides of the movable block 202 to open and close along the adjustment groove 201. After the first clamping plate 203 and the second clamping plate 204 on both sides of the movable block 202 move outward to the outer end of the adjustment groove 201, the movable blocks 202 on both sides of the mold cavity 101 are adjusted by the servo motor 206. After the movable blocks 202 on both sides of the mold cavity 101 are adjusted by 180-degree rotation, the first clamping plate 203 and the second clamping plate 204 on both sides of the movable block 202 can be moved back again by the double-headed motor 209. During the movement back of the first clamping plate 203 and the second clamping plate 204, the positioning columns 302 at the inner ends of the first clamping plate 203 and the second clamping plate 204 can be used to position the movable blocks 202 in the positioning holes 301 on both sides of the movable blocks 202, and the movable blocks 202 can be clamped after positioning, thereby ensuring the stability and position accuracy of the movable blocks 202 after adjustment.

[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
