[0030] The control mechanism 4 includes a second mounting shell 41. The second mounting shell 41 is fixedly connected to the left end of the mounting box 1.

[0034] The working principle of a multi-station synchronous injection molding equipment for speaker injection molded parts based on Embodiment 1 is as follows:
[0035] First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation.
[0036] Secondly, when the speaker injection molded parts are injection molded by the multi-station synchronous injection molding machine body 2, the vibration of the multi-station synchronous injection molding machine body 2 causes the laser scanner 35 to vibrate. When the laser scanner 35 vibrates, it causes the sliding rod 34 to move upward, and the sliding rod 34 causes the toothed plate 33 to move upward. At this time, the toothed plate 33 squeezes the spring 32. Then, during the upward movement, the toothed plate 33 synchronously drives the gear 36 to rotate. The gear 36 drives the rotating block 37 to rotate through its right end gear rod. The rotating block 37 drives the second rotating rod 39 to rotate through the first rotating rod 38. The second rotating rod 39 drives the torsion spring 310 to twist. During vibration, the laser scanner 35 is damped by the recovery of the spring 32 and the torsion spring 310 to prevent deviations in the later inspection results. After the speaker injection molded parts are injection molded by the multi-station synchronous injection molding machine body 2, they are inspected by the laser scanner 35 to ensure the surface quality of the product.
[0037] Third, when protection is required, the four sets of electromagnetic blocks 410 at the top and rear end of the fixed plate 42 are driven by an external current output device to work in stages. This causes the moving block 411 to move forward due to the magnetic attraction of the electromagnetic blocks 410. The moving block 411 drives the top control switch 412 to move forward, and then the motor 44 is started. The motor 44 drives the gear set 43 to rotate, the gear set 43 drives the turntable 45 to rotate, and the turntable 45 drives the figure-eight slide groove 46 to rotate. This causes the two sets of moving rods 47 to move relative to each other due to the influence of the figure-eight slide groove 46, thereby gradually increasing the distance between the two sets of moving rods 47. Two sets of moving rods 47 drive two sets of contact blocks 48 to move relative to each other at the top of the second mounting shell 41, thereby pressing the control switch 412 at the rear end of the top of the fixed plate 42 through the contact blocks 48. The control switch 412 controls the electric sliding door 5 to move downward, ensuring operational safety and reducing the risk of workplace injury. When the electric sliding door 5 needs to be raised, the external current output device drives the four sets of electromagnetic blocks 410 at the front end of the top of the fixed plate 42 to work step by step, causing the control switch 412 at the front end of the top of the fixed plate 42 to move backward. Repeating the above steps, the electric sliding door 5 is raised.
[0038] This utility model provides an improved multi-station synchronous injection molding equipment for speaker injection molded parts. It includes a detection mechanism 3, which uses springs 32 and torsion springs 310 to dampen the laser scanner 35, preventing deviations in subsequent inspection results. The laser scanner 35 is used to inspect the speaker injection molded parts, ensuring product surface quality. A control mechanism 4 is also included, which uses a contact block 48 to press a control switch 412, controlling the operation of the electric sliding door 5, ensuring operational safety and reducing the risk of workplace injuries.
