[0027] By adopting the inclined guide column 140 in conjunction with the inclined guide hole 320, when the rear template 200 approaches or moves away from the front template 100, the first core-pulling part 310 will slide under the action of the inclined guide column 140, so that the first core-pulling part 310 can enter or leave the first cavity, thereby realizing automatic core insertion or automatic core pulling without the need for power, making the structure reasonable and compact, reducing production costs, and improving work stability and reliability.
[0028] Reference Figures 1 to 4, wherein the rear template 200 is provided with a first slide groove 230, the first core pulling part 310 is provided with a first connecting block 330, the first connecting block 330 is arranged on the first slide groove 230, and the oblique guide hole 320 is arranged on the first connecting block 330.

Further, the first slide groove 230 is provided with a perforation 240, and the perforation 240 is set as an elongated hole, and the perforation 240 is adapted to the oblique guide hole 320. By providing the perforation 240 in the first slide groove 230, the thickness of the first connecting block 330 can be reduced, the overall weight can be reduced, and the operation is convenient.
[0029] Reference Figures 1 to 4 In some embodiments, the front template 100 is provided with a first front fixing rod 150 and a second front fixing rod 160, the first front fixing rod 150 is inserted into the front mold 110, and the second front fixing rod 160 is inserted into the first insert 120. During installation, the front mold 110 and the first insert 120 are placed at corresponding positions on the front template 100, and then the front mold 110 and the first insert 120 are fixed by the first front fixing rod 150 and the second front fixing rod 160 respectively; when the front mold 110 and the first insert 120 need to be removed, the first front fixing rod 150 and the second front fixing rod 160 can be taken out accordingly, which is simple to disassemble, and is convenient for replacing the front mold 110 and the first insert 120, thereby improving work efficiency. Similarly, the rear template 200 is provided with a first rear fixing rod 250 and a second rear fixing rod 260, the first rear fixing rod 250 is inserted into the rear mold 210, and the second rear fixing rod 260 is inserted into the second insert 220. The rear mold 210 and the second insert 220 are fixed by the first rear fixing rod 250 and the second rear fixing rod 260, which facilitates assembly and disassembly and improves work efficiency.
[0030] The front mold 110 is provided with a groove 170, and the rear mold 210 is provided with a protrusion 270, and the protrusion 270 is connected with the groove 170.

When the front mold 110 contacts the rear mold 210, the groove 170 and the protrusion 270 cooperate with each other. By adopting the cooperation between the groove 170 and the protrusion 270, the mold clamping accuracy can be improved, and the molding quality of the gearbox bracket can be effectively improved.
[0031] Reference Figures 1 to 4, further, the core pulling assembly also includes a second core pulling part 340, which is slidably arranged on the side of the rear template 200 away from the first core pulling part 310, and the second core pulling part 340 slides to enter the first cavity and connects with the first core pulling part 310. Through the cooperation of the first core pulling part 310 and the second core pulling part 340, the internal hollow cut can be obtained to penetrate the gearbox bracket on both sides, making the function of the mold more diverse. It can be imagined that the rear template 200 is provided with a second slide groove 280, and the second core pulling part 340 is provided with a second connecting block 350, and the second connecting block 350 is arranged in the second slide groove 280. The second connecting block 350 slides along the second slide groove 280 to drive the second core pulling part 340 to slide, thereby realizing the automatic core insertion or automatic core pulling of the second core pulling part 340, and the operation is simple. It is easy to understand that the second connecting block 350 is connected to a driving member 360, and the driving member 360 is set as a cylinder, and the driving member 360 drives the second connecting block 350 to slide. The second connecting block 350 is driven to slide by the driving member 360 to drive the second core-pulling part 340 to slide, which has a simple structure and stable operation. Of course, the sliding mode of the second core-pulling part 340 can also be the same as the sliding mode of the first core-pulling part 310, and this application does not limit this.
[0032] Reference Figure 1 and Figure 2 In some embodiments, the gearbox bracket molding mold further includes a push assembly 400, which includes a push plate 410 and a push rod 420. The push plate 410 is slidably disposed on the side of the rear mold plate 200 away from the front mold plate 100, and the push rod 420 is disposed on the push plate 410. The push plate 410 slides to push the push rod 420 out of the gearbox bracket. When the injection molding is completed and the mold is cooled and opened, the push plate 410 moves toward the side of the rear mold plate 200. At this time, the push rod 420 passes through the rear mold 210 and is exposed on the surface of the first cavity to push out the gearbox bracket, which is convenient for taking the gearbox bracket and improving the convenience during use.
