Description

Technical Field

[0001] The invention relates to a mold detection device, in particular to a six-station layered injection automobile lamp transparent mold detection device. Background Art

[0002] Automobile lenses are plastic products, and in order to reduce production costs and improve production efficiency, injection molds are selected to produce automobile lamp housings.

[0003] At present, a Chinese patent with application publication number CN118641121A discloses a mold detection device for automobile two-color headlights, including a detection frame, a double-headed screw drive member is arranged on the top of the detection frame, the double-headed screw drive member is connected to a mold fixing member, the mold fixing member is installed with a fixed mold and a movable mold, an inflation detection mechanism is installed on the mold fixing member, a movable mold model and a fixed mold model are installed at both ends of the detection frame, and a rack is symmetrically installed on the top of the detection frame.

[0004] When the air tightness test is performed on the mold, the two molds can be driven to move by a double-headed screw drive, and then the molds can be assembled and tested for air tightness and tested separately by cooperating with the rack during the movement, so that it can be quickly determined which part of the mold has an air tightness problem, and the entire testing process only requires the staff to install the mold once, which reduces labor intensity and improves testing efficiency and accuracy.

[0005] However, the thickness of automobile lenses usually reaches 21mm. If the wall thickness is too thick, one-time molding will cause problems such as uneven stress and warping. Therefore, multiple injection molding is required, and the thickness of each injection molding is between 3-3.5mm. This requires testing the thickness of each injection molding. This kind of detection device for automobile dual-color headlight molds obviously does not have the function of detecting thickness. Summary of the invention

[0006] In view of this, the purpose of the present invention is to provide a six-station layered injection automobile lamp transparent mold detection equipment to achieve the purpose of being able to detect product thickness.

[0007] In order to solve the above technical problems, the technical solution of the present invention is: a six-station layered injection automobile lamp transparent mold detection equipment, including a frame, the frame is slidably connected to a driving rod along its length direction, the frame is slidably connected to a support rod along its height direction, the support rod is connected to a support frame, the support frame is connected to a contact rod for contacting with a mold or a product at one end away from the support rod, and a distance sensor is arranged on the frame, and the distance sensor corresponds to the support frame;

[0008] The driving rod moves along its own length direction and rotates the support rod through the conductive structure to make the contact rod correspond to the mold or product. After the driving rod continues to move, the support rod moves along its own length direction and makes the contact rod contact the mold or product.

[0009] To implement the above technical solution, the upper mold and the lower mold of the mold are separated, the driving rod is moved forward along its own length direction, the support rod is rotated through the conduction structure, so that the contact rod corresponds to the cavity of the lower mold, and as the driving rod continues to move, the support rod moves along its own length direction, so that the contact rod contacts the inner wall of the cavity. At this time, the driving rod cannot continue to move, and the distance sensor measures the distance a between the support frame; the driving rod is moved backward along its own length direction, the support rod is moved up and the contact rod is separated from the inner wall of the cavity, and as the driving rod continues to move backward, the contact rod leaves from between the upper mold and the lower mold; after the injection molding is completed, the upper mold and the lower mold are separated. Similarly, the driving rod is moved forward again. At this time, the contact rod can contact the product in the cavity, and the distance sensor measures the distance b between the support frame. The thickness of the product can be obtained by subtracting the distance a from the distance b, thereby achieving the purpose of detecting the thickness of the product.

[0010] As a preferred embodiment of the present invention, the conduction structure includes a bevel rack, a bevel gear, an L-shaped groove and a guide bolt, the bevel rack is fixed on the driving rod, the bevel gear is fixed on the support rod and is coaxially arranged, the bevel rack is meshed with the bevel gear, the L-shaped groove is opened on the outer wall of the support rod and includes a vertical portion and a horizontal portion, the vertical portion is parallel to the axis of the support rod, the horizontal portion is perpendicular to the vertical portion, and the guide bolt is connected to the frame and is slidably connected to the L-shaped groove.

[0011] To implement the above technical solution, the driving rod is moved forward, the bevel rack drives the bevel gear to rotate, and the guide bolt is slidably connected in the horizontal part, so that the support rod rotates along its own axis. When the connection between the horizontal part and the vertical part corresponds to the guide bolt, the support rod cannot continue to rotate. As the driving rod continues to move forward, since the bevel rack and the bevel gear have bevel teeth, the bevel teeth have guiding properties. Therefore, as the driving rod continues to move, the support rod moves downward along its own axis, so that the contact rod can contact the inner wall of the cavity or the product. Similarly, when the driving rod moves backward, the support rod can be moved up first and then rotated, so that the contact rod is moved out of the cavity and then moved to the outside of the mold.

[0012] As a preferred solution of the present invention, an adjusting rod is fixedly connected to the contact rod, the adjusting rod is threadedly connected to the adjusting hole on the support frame, and the support frame is connected to the adjusting rod via a positioning assembly.

[0013] To implement the above technical solution, the contact rod is rotated and the adjusting rod is threadedly connected to the adjusting hole, thereby adjusting the height position of the contact rod to adapt to cavities of different depths, thereby improving practicality.

[0014] As a preferred embodiment of the present invention, the positioning assembly includes a positioning hole, a positioning rod, a screw sleeve, a guide ring, and a guide slope. The positioning hole is opened on the support frame and is connected to the adjustment hole. The positioning rod is slidably connected in the positioning hole and is used to interfere with the adjustment rod. The guide ring is fixed on the screw sleeve. The guide slope is opened on the inner wall of the guide ring and is used to interfere with the end of the positioning rod. The screw sleeve is threadedly connected to the support frame.

[0015] To implement the above technical solution, the adjusting rod moves along its own axial direction as the contact rod rotates. After the position of the contact rod is adjusted, the screw sleeve is threadedly connected to the frame so that the guiding bevel contacts the end of the positioning rod. Through the guiding effect of the guiding bevel, the positioning rod and the adjusting rod are tightly pressed against each other to limit the rotation of the adjusting rod, making it difficult for the contact rod to move, thereby improving the measurement accuracy.

[0016] As a preferred solution of the present invention, a solid-state pressure sensor is fixedly connected to the end of the contact rod, and the solid-state pressure sensor is electrically connected to the distance measuring sensor through a controller.

[0017] To implement the above technical solution, when the solid-state pressure sensor contacts the product, after the pressure reaches a threshold, the solid-state pressure sensor sends an electrical signal to the controller, and the controller sends an electrical signal to the distance measuring sensor, which is not likely to cause damage to the product.

[0018] As a preferred solution of the present invention, the frame is provided with a wiping block for contacting the end of the contact rod.

[0019] To implement the above technical solution, after the contact rod collides with the mold or product, it rotates with the rotation of the support rod, causing the contact rod to collide with the wiping block, so that the wiping block wipes off foreign matter on the end of the contact rod and foreign matter on the solid-state pressure sensor, thereby achieving the purpose of improving measurement accuracy.

[0020] As a preferred solution of the present invention, a storage groove is provided on the frame, a drainage port is provided on the side wall of the frame, a sealing plug is provided at the drainage port, and a cleaning liquid for cleaning the wiping block is injected into the storage groove.

[0021] To implement the above technical solution, the cleaning liquid is injected into the storage tank, and the wiping block is immersed in the cleaning liquid, which can clean the wiping block and improve the cleaning power of the end of the contact rod and the solid-state pressure sensor; after the sealing plug is pulled out, the cleaning liquid can be discharged from the drain port to facilitate the replacement of the cleaning liquid.

[0022] As a preferred solution of the present invention, a conduction component is arranged between the driving rod and the wiping block; the driving rod moves forward through the conduction component to move the wiping block downward and then immersed in the cleaning liquid; the driving rod moves backward through the conduction component to move the wiping block upward and contact with the end of the contact rod.

[0023] To implement the above technical solution, the driving rod is moved backward, and the wiping block is moved upward through the conductive component so that the wiping block contacts the end of the contact rod and the solid-state pressure sensor; the driving rod is moved forward, and the wiping block is moved downward and immersed in the cleaning liquid to clean the wiping block.

[0024] As a preferred solution of the present invention, the conduction component includes a connecting block, a connecting rod, and a connecting plate. The connecting block is fixed on the driving rod, a connecting inclined surface is provided on the connecting block, the connecting plate is fixed on the frame, a connecting groove is provided on the connecting plate, one end of the connecting rod is slidably connected to the connecting inclined surface, the other end of the connecting rod is connected to the wiping block, and the middle part of the connecting rod is slidably connected in the connecting groove.

[0025] To implement the above technical solution, the driving rod is moved forward, and the end of the connecting rod is gradually moved downward along the connecting inclined surface by gravity. At the same time, the connecting rod and the wiping block are moved downward and immersed in the cleaning liquid; the driving rod is moved backward, and the connecting rod drives the wiping block to move upward by the conduction effect of the connecting inclined surface, and the wiping block is removed from the cleaning liquid.

[0026] As a preferred solution of the present invention, the wiping block is made of a sponge block.

[0027] By implementing the above technical solution, the sponge block can absorb a small amount of cleaning liquid to further enhance the cleaning capability of the end of the contact rod and the solid-state pressure sensor; meanwhile, the production cost is relatively low.

[0028] In summary, the present invention has the following beneficial effects:

[0029] 1. The driving rod moves forward, and the contact rod rotates a certain angle to correspond to the cavity. The driving rod continues to move forward, which can move the contact rod downward and make the solid-state pressure sensor contact the inner wall of the cavity or the product.

[0030] 2. When the driving rod moves forward, the wiping block is immersed in the cleaning liquid to clean the wiping block; when the driving rod moves backward, the wiping block is removed from the cleaning liquid.

[0031] 3. The driving rod moves backward, the contact rod moves upward and separates from the inner wall of the cavity or the product. The driving rod continues to move backward, so that the contact rod can rotate along the axis of the support rod and contact the wiping block, so that the wiping block cleans the end of the contact rod and the solid-state pressure sensor, thereby improving the measurement accuracy.

DETAILED DESCRIPTION

[0040] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0041] A six-station layered injection automobile lamp transparent mold inspection equipment includes a horizontally placed frame 1, the frame 1 is slidably connected to a driving rod 11 along its length direction, and the driving rod 11 is horizontally arranged. The frame 1 is slidably connected to a support rod 2 along its height direction, and the support rod 2 is vertically arranged. A support frame 21 is fixedly connected to the upper end of the support rod 2. A contact rod 3 is connected to the end of the support frame 21 away from the support rod 2, and the contact rod 3 is vertically arranged. A distance sensor 5 is arranged on the frame 1, and the distance sensor 5 corresponds to the support frame 21.

[0042] The driving rod 11 moves forward along its length direction, and rotates the support rod 2 through the conductive structure 4 to make the contact rod 3 correspond to the mold or product. The driving rod 11 continues to move to move the support rod 2 downward, and makes the contact rod 3 contact the mold cavity or product. The driving rod 11 is driven by a standard cylinder 12, and the standard cylinder 12 is fixed on the frame 1.

[0043] The transmission structure 4 includes a bevel rack 41, a bevel gear 42, an L-shaped groove 43 and a guide bolt 44. The bevel rack 41 is fixed to the side wall of the driving rod 11, and the length direction of the bevel rack 41 is parallel to the length direction of the driving rod 11. The bevel gear 42 is fixed to the support rod 2 and is coaxially arranged; the bevel rack 41 is meshed with the bevel gear 42.

[0044] The L-shaped slot 43 is formed on the outer wall of the support rod 2 and includes a vertical portion 431 and a horizontal portion 432. The length direction of the vertical portion 431 is parallel to the axis of the support rod 2, and the horizontal portion 432 is perpendicular to the vertical portion 431. The guide bolt 44 is threadedly connected to the frame 1 and slidably connected to the L-shaped slot 43.

[0045] When the driving rod 11 is moved forward, the bevel rack 41 drives the bevel gear 42 to rotate, the support rod 2 rotates synchronously with the bevel gear 42, and the guide bolt 44 is slidably connected in the horizontal part 432, so that the support rod 2 rotates horizontally along its own axis. When the connection between the horizontal part 432 and the vertical part 431 corresponds to the guide bolt 44, the support rod 2 cannot continue to rotate. As the driving rod 11 continues to move forward, the guide bolt 44 is slidably connected in the vertical part 431. Since the bevel rack 41 and the bevel gear 42 have bevel teeth, the bevel teeth have guiding properties. Therefore, as the driving rod 11 continues to move, the support rod 2 moves downward along its own axis, so that the contact rod 3 can contact the inner wall of the cavity or the product.

[0046] Similarly, when the driving rod 11 moves backward, the support rod 2 can be moved up first until the guide bolt 44 is located at the connection between the straight part and the horizontal part 432 and then rotated. The guide bolt 44 is slidably connected to the horizontal part 432 by the vertical part 431, so that the contact rod 3 is moved out of the cavity and then moved to the outside of the mold.

[0047] Thus, when the contact rod 3 contacts the inner wall of the cavity, the distance sensor 5 measures the distance a between the contact rod 3 and the support frame 21; when the contact rod 3 contacts the product in the cavity, the distance sensor 5 measures the distance b between the contact rod 3 and the support frame 21. The thickness of the product can be obtained by subtracting the distance a from the distance b, thereby achieving the purpose of detecting the thickness of the product. The distance sensor 5 is an infrared distance sensor 5.

[0048] In order to adapt to cavities of different depths, an adjusting rod 31 is fixedly connected to the contact rod 3. The adjusting rod 31 is coaxially arranged with the contact rod 3 and is threadedly connected to an adjusting hole on the support frame 21. The support frame 21 is connected to the adjusting rod 31 through a positioning assembly 6.

[0049] The positioning assembly 6 comprises a positioning hole 61, a positioning rod 62, a screw sleeve 63, a guide ring 64, and a guide slope 65. The positioning hole 61 is provided on the support frame 21 and communicated with the adjustment hole, and the axis of the positioning hole 61 is perpendicular to the axis of the adjustment hole. The positioning rod 62 is slidably connected in the positioning hole 61 and is used to conflict with the adjustment rod 31. The guide ring 64 is fixed on the screw sleeve 63, and the guide ring 64 and the screw sleeve 63 are coaxially arranged. The guide slope 65 is provided on the inner wall of the guide ring 64 and is used to conflict with the end of the positioning rod 62. The screw sleeve 63 is threadedly connected to the support frame 21, and the screw sleeve 63 moves in the direction close to the positioning rod 62. The positioning rod 62 is pressed by the guide slope 65, so that the positioning rod 62 is pressed on the adjustment rod 31, so that the adjustment rod 31 is not easy to rotate, and the positioning of the screw sleeve 63 is realized by the friction between the screw sleeve 63 and the support frame 21, and at the same time, the contact rod 3 is not easy to move.

[0050] A solid-state pressure sensor 32 is fixedly connected to the end of the contact rod 3, and the solid-state pressure sensor 32 is electrically connected to the distance measuring sensor 5 through the controller 13. The controller 13 is fixed on the frame 1, and the controller 13 is a PLC controller.

[0051] The frame 1 is provided with a wiping block 71 for contacting the end of the contact rod 3 , and the wiping block 71 is a sponge block.

[0052] A storage tank 7 with a square cross section is provided on the frame 1, and a drain port 72 is provided on the side wall of the frame 1, and the drain port 72 is connected to the storage tank 7. A sealing plug 73 made of rubber is provided at the drain port 72, and a cleaning liquid for cleaning the wiping block 71 is injected into the storage tank 7. The cleaning liquid is a diluted alcohol solution.

[0053] A conduction assembly 8 is provided between the driving rod 11 and the wiping block 71. The conduction assembly 8 includes a connecting block 81, a connecting rod 82, and a connecting plate 83. The connecting block 81 is fixed to the driving rod 11, and a connecting inclined surface 811 is provided on the connecting block 81, and the cross section of the connecting block 81 is a right triangle. The connecting plate 83 is fixed to the frame 1, and a connecting groove 831 is provided on the connecting plate 83, and the length direction of the connecting groove 831 is vertically arranged. One end of the connecting rod 82 is slidably connected to the connecting inclined surface 811, and the other end of the connecting rod 82 is fixedly connected to the wiping block 71. The middle part of the connecting rod 82 is slidably connected to the connecting groove 831.

[0054] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
