Description

Technical Field

[0001] The utility model relates to the technical field of multi - cavity precision mold detection, and particularly relates to a stress distribution detection device for multi - cavity precision molds. Background Technique

[0002] Before a multi - cavity precision mold works, it is necessary to detect the stress distribution of the mold to ensure that the mold can work well during the working process without failures. Therefore, after the multi - cavity precision mold is produced, a stress distribution detection device is needed to detect the mold.

[0003] Existing stress distribution detection devices need to be in contact with the mold during the working process for detection. However, if the position where the mold is placed is not horizontal, such stress distribution detection devices cannot make good contact with the mold during the moving process, thus affecting the detection effect of the device and not being able to well meet people's usage requirements. In view of the above situation, technological innovation is carried out on the basis of existing stress distribution detection devices. Summary of the Invention

[0004] The purpose of the utility model is to provide a stress distribution detection device for multi - cavity precision molds to solve the problem that generally cannot well meet people's usage requirements proposed in the above - mentioned background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A stress distribution detection device for multi - cavity precision molds includes a base assembly and an elastic assembly. A power assembly is installed above the base assembly. The elastic assembly is located at the lower middle part of the power assembly, and the elastic assembly includes a moving frame, a first spring, a first guide rod, and a connecting frame. The middle part of the lower end of the moving frame is connected with a first spring, and the left and right sides of the moving frame are penetrated by the first guide rod. The lower end of the first spring is connected with the connecting frame.

[0006] Further, the base assembly includes a bottom plate, a multi - cavity precision mold body, a clamping plate, a first cylinder, and a mounting frame. The multi - cavity precision mold body is placed in the middle of the upper end of the bottom plate. Clamping plates are arranged on the left and right sides of the multi - cavity precision mold body, and a first cylinder is connected to the side of the clamping plate far from the multi - cavity precision mold body. The outside of the first cylinder is connected with the mounting frame.

[0007] Further, the power assembly includes a first electric slide rail, a second cylinder, and a second electric slide rail. The upper end of the first electric slide rail is connected with the second cylinder, and the upper end of the second cylinder is connected with the second electric slide rail.

[0008] Further, the lower end of the elastic assembly is connected with a transmission assembly, the lower end of the transmission assembly is connected with a support assembly, and a cleaning assembly is connected around the support assembly.

[0009] Furthermore, the transmission assembly includes a receiving disc, a motor, a first gear, a second gear, a first sprocket, a chain, a second sprocket and an eccentric rotating block. A motor is installed at the upper end of the receiving disc. The rotating end of the motor is connected to the first gear, and the second gear is connected around the first gear. The lower end of the second gear is connected to the first sprocket, and the chain is connected to the outside of the first sprocket. One end of the chain away from the first sprocket is connected to the second sprocket, and the lower end of the second sprocket is connected to the eccentric rotating block.

[0010] Furthermore, the support assembly includes a mounting disc, a stress detector, support columns and steel balls. A stress detector is installed in the middle of the lower end of the mounting disc. Support columns are installed around the lower end of the mounting disc, and steel balls are inlaid and connected to the lower ends of the support columns.

[0011] Furthermore, the cleaning assembly includes a fixing plate, a second spring, a second guide rod and a cleaning plate. A second spring is connected to one side of the fixing plate away from the mounting disc. A second guide rod is installed inside the second spring, and the end of the second spring away from the fixing plate is connected to the cleaning plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The device has an elastic structure. Through the elastic structure, the stress detector can have a continuous force. In this way, even if the mold is tilted, the stress detector can still ensure contact with the mold, facilitating the operation of the stress detector. The device has a cleaning structure, which can prevent debris on the surface of the mold from affecting the movement of the stress detector, thus making it inconvenient for the stress detector to work.

[0013] 1. The elastic structure formed by the connecting frame, the first guide rod and the first spring between the moving frame enables the stress detector to have a certain compensation structure. When the stress detector moves and detects that the multi-cavity precision mold body is tilted, the stress detector can still achieve distance compensation through the elastic structure, ensuring that the stress detector is always in contact with the multi-cavity precision mold body, thus facilitating the stress detector to detect the surface of the multi-cavity precision mold body.

[0014] 2. The motor drives the eccentric rotating block to rotate. When the stress detector moves and encounters debris on the multi-cavity precision mold body, the cleaning plate will clean the debris away. If the debris adheres tightly, the eccentric rotating block will collide with the cleaning plate, causing the cleaning plate to move back and forth on the second guide rod, thus knocking off the debris, facilitating the contact between the stress detector and the multi-cavity precision mold body, and thus facilitating stress detection.

[0019] As Figure 1 shown, a stress distribution detection device for a multi-cavity precision mold includes a base assembly 1 and an elastic assembly 3. A power assembly 2 is installed above the base assembly 1. The elastic assembly 3 is located at the lower middle part of the power assembly 2. The elastic assembly 3 includes a moving frame 301, a first spring 302, a first guide rod 303 and a connecting frame 304. The lower middle part of the moving frame 301 is connected with a first spring 302. The left and right sides of the moving frame 301 penetrate through the first guide rod 303. The lower end of the first spring 302 is connected with a connecting frame 304.

[0020] Relying on the elastic structure formed between the connecting frame 304, the first guide rod 303 and the first spring 302 with the moving frame 301, the stress detector 502 can have a certain compensation structure. In this way, if it is found that the multi-cavity precision mold body 102 is tilted during the movement of the stress detector 502, the stress detector 502 can still achieve distance compensation through the elastic structure, so as to ensure that the stress detector 502 is always in contact with the multi-cavity precision mold body 102, thus facilitating the stress detector 502 to detect the surface of the multi-cavity precision mold body 102.

[0021] As Figure 1As shown, the base assembly 1 includes a base plate 101, a multi-cavity precision mold body 102, a clamping plate 103, a first cylinder 104, and a mounting bracket 105. The multi-cavity precision mold body 102 is placed in the middle of the upper end of the base plate 101. Clamping plates 103 are arranged on the left and right sides of the multi-cavity precision mold body 102. A first cylinder 104 is connected to the side of the clamping plate 103 away from the multi-cavity precision mold body 102, and a mounting bracket 105 is connected to the outside of the first cylinder 104.

[0022] As Figure 1 shown, the power assembly 2 includes a first electric slide rail 201, a second cylinder 202, and a second electric slide rail 203. The second cylinder 202 is connected to the upper end of the first electric slide rail 201, and the second electric slide rail 203 is connected to the upper end of the second cylinder 202.

[0023] As Figure 2 and Figure 3 shown, the lower end of the elastic assembly 3 is connected to the transmission assembly 4, the lower end of the transmission assembly 4 is connected to the support assembly 5, and a cleaning assembly 6 is connected to the periphery of the support assembly 5.

[0024] As Figure 2 shown, the transmission assembly 4 includes a receiving disc 401, a motor 402, a first gear 403, a second gear 404, a first sprocket 405, a chain 406, a second sprocket 407, and an eccentric rotating block 408. The motor 402 is installed on the upper end of the receiving disc 401. The rotating end of the motor 402 is connected to the first gear 403. The second gear 404 is connected to the periphery of the first gear 403. The lower end of the second gear 404 is connected to the first sprocket 405. The chain 406 is connected to the outside of the first sprocket 405. One end of the chain 406 away from the first sprocket 405 is connected to the second sprocket 407. The lower end of the second sprocket 407 is connected to the eccentric rotating block 408;

[0025] The motor 402 drives the second gear 404 to rotate through the first gear 403, so that the first sprocket 405, the chain 406, and the second sprocket 407 drive the eccentric rotating block 408 to rotate, and the eccentric rotating block 408 pushes the cleaning plate 604.

[0026] As Figure 3 shown, the support assembly 5 includes a mounting disc 501, a stress detector 502, support columns 503, and steel balls 504. The stress detector 502 is installed in the middle of the lower end of the mounting disc 501. Support columns 503 are installed around the lower end of the mounting disc 501. The lower ends of the support columns 503 are inlaid and connected with steel balls 504;

[0027] The mounting disc 501 is supported by the supporting effect of the steel balls 504 and the support columns 503, avoiding damage to the stress detector 502 due to pressure.

[0028] As Figure 2 shown, the cleaning component 6 includes a fixing plate 601, a second spring 602, a second guide rod 603 and a cleaning plate 604. One side of the fixing plate 601 away from the mounting disc 501 is connected with the second spring 602. The second guide rod 603 is installed inside the second spring 602, and one end of the second spring 602 away from the fixing plate 601 is connected with the cleaning plate 604;

[0029] When the eccentric rotating block 408 is driven by the motor 402 to rotate, if debris on the multi-cavity precision mold body 102 is encountered during the movement of the stress detector 502, the debris will be cleaned away by the cleaning plate 604 at this time. If the debris adheres tightly, the eccentric rotating block 408 will collide with the cleaning plate 604 at this time, causing the cleaning plate 604 to move back and forth on the second guide rod 603, so as to knock off the debris, facilitating the contact between the stress detector 502 and the multi-cavity precision mold body 102, and thus facilitating stress detection.

[0030] Working principle: When using this multi-cavity precision mold stress distribution detection device, first place the multi-cavity precision mold body 102 on the bottom plate 101, then turn on the first cylinder 104 to clamp and fix the multi-cavity precision mold body 102 with the clamping plate 103. Then drive the stress detector 502 to descend by the second cylinder 202 until it contacts the multi-cavity precision mold body 102. Then the second cylinder 202 continues to pull down a certain distance, and the elastic structure formed by the connecting frame 304 through the first guide rod 303 and the first spring 302 and the moving frame 301 buffers the stress detector 502 to prevent the stress detector 502 from being damaged. Then drive the stress detector 502 to move on the multi-cavity precision mold body 102 through the first electric slide rail 201 and the second electric slide rail 203 for detection. The mounting disc 501 is supported by the supporting effect of the steel balls 504 and the supporting columns 503 to prevent the stress detector 502 from being damaged due to pressure. While the stress detector 502 is moving, the debris on the surface of the multi-cavity precision mold body 102 will be cleaned by the cleaning plate 604, which can prevent the debris on the multi-cavity precision mold body 102 from affecting the detection effect of the stress detector 502. If the debris adheres tightly, the cleaning plate 604 will compress the second spring 602, so that the cleaning plate 604 will contact the eccentric rotating block 408. At the same time, the motor 402 drives the second gear 404 to rotate through the first gear 403, so that the first sprocket 405, the chain 406 and the second sprocket 407 drive the eccentric rotating block 408 to rotate, and the eccentric rotating block 408 pushes the cleaning plate 604, so that the cleaning plate 604 impacts the adhered debris, and then the adhered debris is cleaned away.
