Description

Technical Field

[0001] This invention relates to the field of mold inspection technology, and in particular to a hot runner mold inspection device for acoustic component processing. Background Technology

[0002] Acoustic components require stringent control over dimensional accuracy, internal uniformity, and appearance defects. Traditional cold runner molds are prone to runner solidification, resulting in significant material loss, long molding cycles, and the appearance of weld lines, shrinkage marks, and density inconsistencies, directly impacting acoustic consistency. Hot runner molds, on the other hand, maintain the molten state through a heating system, improving filling stability and product consistency, and are increasingly being used in the production of precision acoustic components such as speaker and microphone housings.

[0003] In the traditional process of runner mold inspection, mold positioning often relies on manual adjustment or simple fixtures, which has problems such as low positioning accuracy and poor stability. This can easily lead to misalignment between the spray nozzle and the inspection component, affecting the reliability of the inspection results. Although some inspection equipment is equipped with a drive adjustment structure, it lacks an integrated positioning and drive coordination mechanism, making it difficult to achieve precise alignment between the spray nozzle and the sampling component. At the same time, most existing inspection devices do not have a dedicated sampling hopper, which makes it impossible to collect the sprayed material stably and efficiently. This can easily lead to material spillage, incomplete collection, and other problems, making it difficult to meet the requirements of online accurate inspection of runner molds. Summary of the Invention

[0016] In summary, the present invention has the following beneficial effects:

[0017] 1. The present invention has a reasonable structure. The first motor causes the rotating rod to rotate. A docking plate is fixedly connected to the bottom end of the rotating rod. The rotation of the rotating rod causes the docking plate to rotate. The rotation of the docking plate pulls the coupling joint on the column to move through the linkage plate on the shaft pin. The coupling joint is fixedly connected to one end of the adjusting rod. The movement of the coupling joint causes the adjusting rod to move. The pulley will rotate in contact with the surface of the adjusting rod, increasing the stability of the movement of the adjusting rod.

[0018] 2. In this invention, the hot runner mold to be tested is placed inside the shelf, and then the support is moved by the movement of the adjusting rod. The top of the support is fixedly connected to the crossbar. The movement of the support moves the crossbar. Push rods are movably inserted at both ends of the crossbar, and springs are sleeved on the push rods. The spring force makes the clamps on the push rods tightly fit against the side of the hot runner mold, thereby facilitating the fixing of the hot runner mold inside the shelf.

[0019] 3. In this invention, the main shaft is rotated by the operation of the second motor. The rotation of the main shaft drives the rollers on the driven plate to slide inside the slide groove, which facilitates the lateral movement of the limit plate and the horizontal plate on the first slider. The movement of the horizontal plate causes the limit plate to move, which facilitates the sampling bucket to the top position of the hot runner mold. The arm plate is pushed downward by the lead screw, which facilitates the sliding of the second slider on the slide rail, increasing the stability of the arm plate movement. The downward movement of the arm plate causes the bottom position of the sampling bucket to dock with the spray head on the hot runner mold. The spraying status and temperature of the hot runner mold are detected by the detection probe. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example: Reference Figure 1 - Figure 8The hot runner mold inspection device for acoustic component processing shown includes a base plate 1 with round holes 101 at its four corners. A processing table 102 is fixedly connected to the center of the top surface of the base plate 1. A control panel 103 is fixedly installed on the surface of the processing table 102. A shelf 104 is fixedly connected to the center of the top surface of the processing table 102. Clamping plates 105 are slidably connected to the two sides inside the shelf 104. A through groove 106 with an upward opening is opened in the center of the clamping plate 105. The device also includes a positioning component, a driving component, and a detection component. The positioning component is located on both sides of the shelf 104 to fix the position of the mold. The driving component is located on the bottom surface of the processing table 102 to move the position of the adjusting rod 208. The detection component is located on the base plate 1 to inspect the mold inside the shelf 104.

[0032] Specifically, it should be noted that when using a hot runner mold, heated raw material is injected into the holes inside the mold and then ejected through the nozzle on the mold to fill the cavity. The ejection nozzle of the hot runner mold is sampled and detected by a sampling hopper 409. The raw material from the nozzle enters the interior of the frame 408, and the discharge status and temperature changes can be detected by a detection probe 410. The specific detection method is based on existing technology and will not be elaborated further here.

[0033] As one embodiment of this invention, the positioning component includes guide grooves 2 formed on both sides of the shelf 104. A slide rod 201 is slidably connected inside the guide groove 2. One end of the slide rod 201 is fixedly connected to the output end of the bearing seat 202. The bearing seat 202 is fixedly mounted on the clamping plate 105. A pair of push rods 203 are symmetrically fixedly connected to the outer surface of the clamping plate 105. A collar 204 is fixedly connected to the other end of the pair of push rods 203. A crossbar 205 is slidably connected between the middle ends of the push rods 203. A spring 206 is sleeved on the pair of push rods 203. The two ends of the spring 206 are fixedly connected to one side of the collar 204 and one side of the crossbar 205, respectively. A bracket 207 is fixedly connected to the middle of the bottom surface of the crossbar 205. The bottom end of the bracket 207 is fixedly connected to one end of the lateral position adjustment rod 208.

[0034] Specifically, the hot runner mold to be tested is placed inside the shelf 104. Then, the support 207 is moved by the movement of the adjusting rod 208. The top of the support 207 is fixedly connected to the crossbar 205. The movement of the support 207 moves the crossbar 205. Push rods 203 are movably inserted at both ends of the crossbar 205, and springs 206 are sleeved on the push rods 203. The elastic force of the springs 206 makes the clamping plate 105 on the push rods 203 tightly fit against the side of the hot runner mold, thereby facilitating the fixing of the hot runner mold inside the shelf 104.

[0035] As one embodiment of this invention, the drive assembly includes an adjusting rod 208 movably inserted into the processing table 102. A pair of pulleys 3 are slidably connected to the surface of the adjusting rod 208. The pair of pulleys 3 are rotatably connected to a fixed plate 301. The top end of the fixed plate 301 is fixedly connected to the inner wall of the processing table 102. The other end of the adjusting rod 208 is fixedly connected to a connector 302. A column 303 is fixedly connected to the bottom surface of the connector 302. A linkage plate 304 is rotatably connected to the column 303. The other end of the linkage plate 304 is rotatably connected to a shaft pin 305. The bottom end of the shaft pin 305 is fixedly connected to a docking plate 306. A rotating rod 307 is fixedly connected to the middle of the docking plate 306. The top end of the rotating rod 307 is fixedly connected to the output end of a first motor 308. The first motor 308 is fixedly installed at the middle of the bottom surface of the processing table 102.

[0036] Specifically, the first motor 308 operates to rotate the rotating rod 307. A docking plate 306 is fixedly connected to the bottom end of the rotating rod 307. The rotation of the rotating rod 307 causes the docking plate 306 to rotate. The rotation of the docking plate 306 pulls the coupling joint 302 on the column 303 to move through the linkage plate 304 on the shaft pin 305. The coupling joint 302 is fixedly connected to one end of the adjusting rod 208. The movement of the coupling joint 302 causes the adjusting rod 208 to move. The pulley 3 will rotate against the surface of the adjusting rod 208, increasing the stability of the movement of the adjusting rod 208.

[0037] In one embodiment of this invention, the detection assembly includes a pair of frames 4 fixedly mounted on a base plate 1. A first slider 401 is fixedly connected to the pair of frames 4. A horizontal plate 402 is slidably connected to the lateral position of the first slider 401. A bracket 403 is fixedly connected to one side of the horizontal plate 402. A lead screw 404 is fixedly mounted on the top of the bracket 403. The bottom end of the lead screw 404 is fixedly connected to an arm plate 405. A second slider 406 is fixedly connected to one end of the arm plate 405. The second slider 406 is slidably connected to a slide rail 407, which is fixedly mounted on the bracket 403. The other end of the arm plate 405 is fixedly connected to... There is a frame 408, on which a sampling bucket 409 is installed. A detection probe 410 is fixedly installed on the top surface of the arm plate 405. A limit plate 5 is fixedly connected to the other side of the horizontal plate 402. A sliding groove 501 is opened on the surface of the limit plate 5. A roller 502 is slidably connected inside the sliding groove 501. The roller 502 is rotatably connected to the driven plate 503. The other end of the driven plate 503 is fixedly connected to the main shaft 504. One end of the main shaft 504 is fixedly connected to the output end of the second motor 505. The second motor 505 is fixedly installed in the middle of the positioning frame 506. Both ends of the positioning frame 506 are fixedly connected to the frame body 4.

[0038] Specifically, the operation of the second motor 505 causes the main shaft 504 to rotate. The rotation of the main shaft 504 drives the roller 502 on the driven plate 503 to slide inside the slide groove 501, thereby facilitating the lateral movement of the limit plate 5 and the horizontal plate 402 on the first slider 401. The movement of the horizontal plate 402 causes the limit plate 5 to move, thereby facilitating the movement of the sampling bucket 409 to the top position of the hot runner mold. The screw 404 pushes the arm plate 405 downward, thereby facilitating the sliding of the second slider 406 on the slide rail 407, increasing the stability of the movement of the arm plate 405. The downward movement of the arm plate 405 causes the bottom position of the sampling bucket 409 to dock with the nozzle on the hot runner mold. The detection probe 410 detects the spraying status and temperature of the hot runner mold.

[0039] The working principle of this invention is as follows: The first motor 308 causes the rotating rod 307 to rotate. A docking plate 306 is fixedly connected to the bottom end of the rotating rod 307. The rotation of the rotating rod 307 causes the docking plate 306 to rotate. The rotation of the docking plate 306 pulls the coupling joint 302 on the column 303 to move through the linkage plate 304 on the shaft pin 305. The coupling joint 302 is fixedly connected to one end of the adjusting rod 208. The movement of the coupling joint 302 causes the adjusting rod 208 to move. The pulley 3 will rotate against the surface of the adjusting rod 208, increasing the stability of the movement of the adjusting rod 208.

[0040] The hot runner mold to be tested is placed inside the shelf 104. Then, the support 207 is moved by the movement of the adjusting rod 208. The top of the support 207 is fixedly connected to the crossbar 205. The movement of the support 207 moves the crossbar 205. Push rods 203 are movably inserted at both ends of the crossbar 205. Springs 206 are sleeved on the push rods 203. The elastic force of the springs 206 makes the clamping plate 105 on the push rods 203 tightly fit against the side of the hot runner mold, thereby facilitating the fixing of the hot runner mold inside the shelf 104.

[0041] The operation of the second motor 505 causes the main shaft 504 to rotate. The rotation of the main shaft 504 drives the roller 502 on the driven plate 503 to slide inside the slide groove 501, which facilitates the lateral movement of the limit plate 5 and the horizontal plate 402 on the first slider 401. The movement of the horizontal plate 402 causes the limit plate 5 to move, which facilitates the sampling bucket 409 to the top position of the hot runner mold. The screw 404 pushes the arm plate 405 downward, which facilitates the sliding of the second slider 406 on the slide rail 407, increasing the stability of the movement of the arm plate 405. The downward movement of the arm plate 405 causes the bottom position of the sampling bucket 409 to dock with the nozzle on the hot runner mold. The detection probe 410 detects the spraying status and temperature of the hot runner mold.

[0042] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
