Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a limiting mechanism for a vehicle lamp mold. Background Art

[0002] Automobile vehicle lamps are the main components of automobiles. Some vehicle lamps are provided with thick-wall parts, and light sources are irradiated onto the thick-wall parts. After the light passes through the refraction of the thick-wall parts, the light is emitted, forming an effect of the thick-wall parts emitting light.

[0003] When processing vehicle lamps, molds are used for molding. A mold is a tool for making molded articles. This tool is composed of various parts. Different molds are composed of different parts. It mainly realizes the processing of the outer shape of articles through the change of the physical state of the molded material. When the upper and lower molds are spliced, the limiting guide is realized through the limiting posts on the mold, so that the mold is stably spliced.

[0004] The inventor found in daily work that the existing mold limiting posts are usually installed by interference fit or installed with screws. The above two installation methods are relatively troublesome and not convenient for disassembly. The screws are prone to looseness during the installation process, and it is not convenient to finely adjust the limiting posts, which affects the normal use of the limiting posts, and further leads to the problems of inconvenient disassembly and assembly of the existing limiting posts, instability and difficulty in adjustment. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages of inconvenient disassembly and assembly of the existing limiting posts, instability and difficulty in adjustment, and to propose a limiting mechanism for a vehicle lamp mold.

[0006] To achieve the above object, the utility model adopts the following technical solution: A limit mechanism for a vehicle lamp mold, including an upper mold body and a stabilizing device. Four guiding limit rods are provided on the lower surface of the upper mold body. The stabilizing device is arranged on the surface of the limit rods. The stabilizing device includes a stabilizing member which is slidably connected to the inner wall of the limit rod. The stabilizing member is composed of a cylindrical rod and four stabilizing sliders. The four stabilizing sliders are fixed on the cylindrical rod. Four fixing rings are fixedly connected to the inner wall of the upper surface of the upper mold body. The surfaces of the fixing rings and the upper mold body are both provided with insertion holes adapted to the stabilizing member. The stabilizing member is inserted into the inner walls of the insertion holes. A rotating groove is provided in the inner wall of the fixing ring. A clamping ring is rotatably connected to the inner wall of the rotating groove. A clamping groove is provided on the surface of the stabilizing member. The clamping ring is clamped into the inner wall of the clamping groove. A notch is provided on the surface of the clamping ring. Through the above components, when installing the limit rod, the stabilizing member on the surface of the limit rod is inserted into the insertion holes on the surfaces of the upper mold body and the fixing ring. When the clamping groove on the surface of the stabilizing member is located at the notch on the surface of the clamping ring, rotate the clamping ring to make the clamping ring snap into the clamping groove on the surface of the stabilizing member, so as to quickly and stably limit the limit rod. Both the clamping ring and the stabilizing member are made of high-speed steel material, and the clamping ring has high hardness and wear resistance.

[0007] Preferably, an adjusting screw rod is rotatably connected to the inner wall of the stabilizing member. The adjusting screw rod is threadedly connected to the inner wall of the limit rod. Through the above components, when rotating the adjusting screw rod, the adjusting screw rod can drive the limit rod to slide in the stabilizing member. When sliding and adjusting, it can be observed in cooperation with a caliper to improve the accuracy, so as to realize the fine adjustment of the limit rod and improve the overall flexibility.

[0008] Preferably, one end of the adjusting screw rod is fixedly connected to a rotating head. A hexagonal groove for inserting a tool is provided on the surface of the rotating head. The rotating head is embedded in the stabilizing member. Through the above components, an operator can insert a tool into the hexagonal groove on the surface of the rotating head to drive the screw rod to rotate and realize the fine adjustment of the limit rod.

[0009] Preferably, a push rod is fixedly connected to the surface of the clamping ring. A spring is fixedly connected to one side of the push rod corresponding to the inner wall of the fixing ring. Through the above components, the push rod can control the rotation of the clamping ring, and the spring can drive the push rod and the clamping ring to reset, improving the stable effect of the clamping ring being bound in the clamping groove.

[0010] Preferably, a replacement device is provided at one end of the limiting rod. The replacement device includes a replacement head and a connecting head. The connecting head is fixedly connected to one end of the limiting rod. The replacement head is arranged below the connecting head. The replacement head is sleeved and connected to the connecting head. Screws are installed on the inner wall of the replacement head, and screw holes are formed on the surface of the connecting head. The replacement head is threadedly connected to the screw holes on the surface of the connecting head through the screws. Through the above components, by disassembling the replacement head, the problem of large losses caused by the need to replace the entire limiting rod after wear can be reduced.

[0011] Preferably, three guiding blocks are fixedly connected to the surface of the connecting head. The three guiding blocks are inserted into the inner wall of the replacement head. Through the above components, the three guiding blocks on the connecting head can play a role in positioning the replacement head, facilitating installation.

[0013] 1. In the present utility model, when the mold is used for forming the vehicle lamp, by placing the upper mold body on the lower mold, forming is carried out through the inner cavity of the mold. When the upper mold body is placed on the lower mold, it will be guided and limited by the limiting rod. By setting the stabilizing device, when installing the limiting rod, first push the push rod and the snap ring, the spring is stressed, and the stabilizing member on the surface of the limiting rod is inserted into the jacks on the surface of the upper mold body and the fixed ring. When the slot on the surface of the stabilizing member is located at the notch on the surface of the snap ring, release the push rod, and the spring drives the snap ring to reset, so that the snap ring is stuck into the slot on the surface of the stabilizing member, and the limiting rod can be quickly and stably limited. By setting the stabilizing device, it is convenient to quickly and stably install the limiting column, which can effectively reduce the problems that the existing mold limiting columns are usually installed by interference fit or installed with screws. The above two installation methods are relatively troublesome and not easy to disassemble. The screws are prone to looseness during the installation process, and it is not easy to finely adjust the limiting column, affecting the normal use of the limiting column, thereby improving the overall stability of the equipment.

[0014] 2. In the present utility model, the operator can insert a tool into the hexagonal groove on the surface of the rotating head to drive the screw rod to rotate, realizing fine adjustment of the limiting rod.

[0015] 3. In the present utility model, by setting the replacement device, when the replacement head is worn and needs to be replaced, turn the screw with a tool, and the screw is taken out from the screw hole on the surface of the connecting head, and then the replacement head can be removed from the connecting head for replacement.

[0023] Please refer to Figures 1-5 , this utility model provides a technical solution: a limit mechanism for a vehicle lamp mold, including an upper die body 1 and a stabilizing device 3. Four guiding limit rods 2 are arranged on the lower surface of the upper die body 1. The stabilizing device 3 is arranged on the surface of the limit rod 2, and a replacement device 4 is arranged at one end of the limit rod 2.

[0024] Next, specifically describe the specific settings and functions of its stabilizing device 3 and replacement device 4.

[0025] Specifically, the stabilizing device 3 includes a stabilizing member 32. The stabilizing member 32 is slidably connected to the inner wall of the limit rod 2. The stabilizing member 32 is composed of a cylindrical rod and four stabilizing sliders. The four stabilizing sliders are fixed on the cylindrical rod. Four fixing rings 31 are fixedly connected to the inner wall of the upper surface of the upper die body 1. Jacks adapted to the stabilizing member 32 are provided on the surfaces of the fixing rings 31 and the upper die body 1. The stabilizing member 32 is inserted into the inner wall of the jack. A rotating groove is provided in the inner wall of the fixing ring 31. A snap ring 37 is rotatably connected to the inner wall of the rotating groove. A card slot 34 is provided on the surface of the stabilizing member 32. The snap ring 37 is clamped with the inner wall of the card slot 34. A notch 38 is provided on the surface of the snap ring 37.

[0026] In this implementation: When installing the limit rod 2, the stabilizer 32 on the surface of the limit rod 2 is inserted into the jacks on the surface of the upper die body 1 and the fixed ring 31. When the card slot 34 on the surface of the stabilizer 32 is located at the notch 38 on the surface of the snap ring 37, rotate the snap ring 37 so that the snap ring 37 is snapped into the card slot 34 on the surface of the stabilizer 32, and the limit rod 2 can be quickly and stably limited. Since both the snap ring 37 and the stabilizer 32 are made of high-speed steel material, the snap ring 37 has high hardness and wear resistance.

[0027] Specifically, an adjusting screw 35 is rotatably connected to the inner wall of the stabilizer 32. The adjusting screw 35 is threadedly connected to the inner wall of the limit rod 2. When rotating the adjusting screw 35, the adjusting screw 35 can drive the limit rod 2 to slide in the stabilizer 32. When adjusting by sliding, it can be observed in cooperation with a caliper to improve the accuracy, so as to realize the fine adjustment of the limit rod 2 and improve the overall flexibility.

[0028] Specifically, one end of the adjusting screw 35 is fixedly connected with a rotating head 33. The surface of the rotating head 33 is provided with a hexagonal groove for a tool to be inserted. The rotating head 33 is embedded in the stabilizer 32.

[0029] In this implementation: The operator can insert the tool into the hexagonal groove on the surface of the rotating head 33 to drive the screw to rotate, so as to realize the fine adjustment of the limit rod 2.

[0030] Specifically, a push rod 36 is fixedly connected to the surface of the snap ring 37. One side of the push rod 36 corresponding to the inner wall of the fixed ring 31 is fixedly connected with a spring 39.

[0031] In this implementation: The push rod 36 can control the rotation of the snap ring 37, and the spring 39 can drive the push rod 36 and the snap ring 37 to reset, improving the stable effect of the snap ring 37 being bound in the card slot 34.

[0032] Specifically, the replacement device 4 includes a replacement head 41 and a connection head 45. The connection head 45 is fixedly connected to one end of the limit rod 2. The replacement head 41 is arranged below the connection head 45. The replacement head 41 and the connection head 45 are sleeved and connected. Screws 42 are installed on the inner wall of the replacement head 41. Threaded holes 44 are provided on the surface of the connection head 45. The replacement head 41 is threadedly connected to the threaded holes 44 on the surface of the connection head 45 through the screws 42. In this scheme, the screws 42 are made of stainless steel material to play an anti-corrosion effect. By disassembling the replacement head 41, the problem of large losses caused by the need to replace the entire limit rod 2 after wear can be reduced.

[0033] Specifically, three guide blocks 43 are fixedly connected to the surface of the connection head 45. The three guide blocks 43 are inserted into the inner wall of the replacement head 41.

[0034] In this implementation: The three guiding blocks 43 on the connector 45 can position the replacement head 41 to facilitate installation.

[0035] Working principle: When the mold is used for forming the headlight, the upper die body 1 is placed on the lower die, and the forming is carried out through the inner cavity of the mold. When the upper die body 1 is placed on the lower die, it will be guided and limited by the limiting rod 2. By setting the stabilizing device 3, when installing the limiting rod 2, first push the push rod 36 and the snap ring 37, the spring 39 is stressed, and the stabilizing member 32 on the surface of the limiting rod 2 is inserted into the jacks on the surfaces of the upper die body 1 and the fixing ring 31. When the slot 34 on the surface of the stabilizing member 32 is located at the notch 38 on the surface of the snap ring 37, release the push rod 36, and the spring 39 drives the snap ring 37 to reset, so that the snap ring 37 is snapped into the slot 34 on the surface of the stabilizing member 32, and the limiting rod 2 can be quickly and stably limited. The operator can insert a tool into the hexagonal slot on the surface of the rotating head 33 to drive the screw rod to rotate to realize the fine adjustment of the limiting rod 2. By setting the stabilizing device 3, it is convenient to quickly and stably install the limiting column, which can effectively reduce the problems that the existing mold limiting columns are usually installed by interference fit or installed with screws. The above two installation methods are troublesome and not convenient for disassembly. The screws are prone to looseness during the installation process, and it is not convenient to fine-tune the limiting columns, which affects the normal use of the limiting columns, and thus improves the overall stability of the equipment.

[0036] By setting the replacement device 4, when the replacement head 41 is worn and needs to be replaced, turn the screw 42 with a tool, and take out the screw 42 from the screw hole 44 on the surface of the connector 45, then the replacement head 41 can be removed from the connector 45 for replacement. The replacement head 41 can protect the limiting rod 2, which can effectively reduce the problem that the entire limiting rod 2 needs to be replaced after the head is worn, resulting in a large amount of waste.
