Description

Technical Field

[0001] This utility model relates to the field of wrist rope tensioning and coating technology, and in particular to a dual-station wrist rope tensioning and coating turntable device. Background Technology

[0002] In the existing wrist strap rubber coating production process, a separate injection molding device is usually used to complete the molding of the wrist strap rubber coating part. The lower mold assembly of the wrist strap rubber coating in this type of traditional equipment is a key part of the injection molding process. It is mainly used in conjunction with the upper mold to realize the injection molding operation of the wrist strap rubber coating part. First, the wrist strap to be processed is placed in the lower mold. Then, the upper mold and the lower mold are closed to form a closed cavity, and molten rubber material is injected for rubber coating.

[0003] However, after injection molding, the upper mold must be manually removed to take out the encapsulated product. Then, the product needs to undergo subsequent processes such as sprue treatment before it can be sent to the next processing stage. This operation method is not only cumbersome and time-consuming, but also greatly limits the degree of automation and efficiency improvement in production. Especially in the context of modern manufacturing pursuing high-efficiency and lean production, the complexity and inefficiency of traditional single-station injection molding equipment are particularly prominent, making it difficult to meet the growing demand for automated production and large-scale customization.

[0004] Therefore, it is imperative to redesign a dual-station wrist rope tensioning rubber-coated turntable device. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a dual-station wrist rope tensioning and coating turntable device, which aims to solve the problems of complex and cumbersome operation and difficulty in integrating into automated production in the wrist rope coating injection molding process.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a dual-station wrist strap tensioning and coating turntable device, comprising a machine base, on which a turntable assembly and two wrist strap coating lower mold assemblies are respectively symmetrically arranged on the front and rear sides of the upper surface of the turntable assembly. The wrist strap coating lower mold assembly includes a lower mold, an injection molding inner film disposed in the lower mold, and wrist strap tensioning components symmetrically arranged at both ends of the lower mold. The wrist strap tensioning component includes a tensioning positioning plate and tensioning cylinders symmetrically arranged on both sides of the bottom end of the tensioning positioning plate. Two tensioning sliding grooves are symmetrically arranged on the tensioning positioning plate. A wrist strap positioning post is provided at the output end of the tensioning cylinder. The wrist strap positioning post slides in the tensioning sliding groove. An injection channel is provided in the middle of the injection molding inner film. Wrist strap fixing structures are symmetrically arranged on both sides of the injection channel. A coating groove is provided at the connection between each wrist strap fixing structure and the injection channel.

[0007] Based on the above, the beneficial effects of a dual-station wrist rope tensioning and coating turntable device are that it solves the problems of complex and cumbersome operation and difficulty in integrating into automated production in the existing wrist rope coating injection molding process; mainly reflected in:

[0008] 1. By introducing a dual-station design of the turntable assembly, this utility model allows for the simultaneous operation of surface treatment of the coated part, transfer of the completed wrist rope to the next automated device, and input of the next product to be coated in another wrist rope coating die assembly while one wrist rope coating die assembly is performing the coating process. This continuous operation greatly improves production efficiency and automation, reduces waiting time, and thus meets the needs of high-efficiency production and large-scale customization.

[0009] 2. This utility model replaces the traditional steps of manual tightening and product removal by using a wrist strap tensioning component and a lifting cylinder. The tensioning cylinder drives the wrist strap positioning column to slide in the tensioning sliding groove, realizing automatic tightening and positioning of the wrist strap. The lifting cylinder acts on the lifting hole through the lifting column to eject the rubber-coated part of the wrist strap after injection molding, making the entire rubber-coating process simpler and faster, reducing human intervention and labor intensity.

[0010] Furthermore, the turntable assembly includes a turntable motor and a processing turntable, the processing turntable being disposed at the output end of the turntable motor, and a circular baffle being disposed around the processing turntable on the machine base, the circular baffle being equipped with a stroke sensor.

[0011] Based on the above, the beneficial effects of placing the processing turntable at the output end of the turntable motor are that it enables precise control of the rotation angle and position of the processing turntable, ensuring that each wrist rope rubber-coated lower mold assembly can accurately move to the designated working position, thereby supporting an efficient and automated production process; the beneficial effect of the circular baffle is that it provides a physical barrier for the processing turntable, preventing external factors from jamming the rotation of the processing turntable and improving the safety of equipment operation; the beneficial effect of the stroke sensor is that it monitors the rotation distance of the processing turntable in real time and feeds the data back to the control system, thereby achieving precise control of the position of the processing turntable.

[0012] Furthermore, semi-circular openings are provided on both sides of the coating groove to position the wrist strap welding part that needs to be coated.

[0013] Furthermore, at least one lifting hole is provided in the overmolding groove, the lifting hole penetrates the injection molding inner film, a lifting cylinder is provided at the bottom of the lower mold, and a plurality of lifting columns are connected to the output end of the lifting cylinder, each of the lifting columns is slidably fitted in one of the lifting holes, for lifting the injection-molded wrist strap overmolding part.

[0014] Based on the above, the beneficial effect of the lifting cylinder driving the lifting column is that it realizes the automatic ejection function of the wrist cord rubber-coated part after injection molding, which replaces the traditional manual mold disassembly method, greatly simplifies the operation process, reduces manual intervention, and improves production efficiency.

[0015] Furthermore, wrist strap fixing structures are provided with wrist strap limiting blocks on both sides.

[0016] Based on the above, the beneficial effect of the wrist strap limiting block is to ensure the precise positioning of the wrist strap during the injection molding process.

[0017] Furthermore, the lower mold is provided with upper mold mating holes at its four corners for positioning the upper mold positioning posts located at the four corners at the lower end of the external movable upper mold assembly.

[0018] Based on the above, the beneficial effect of the upper mold mating hole and the upper mold positioning pin is to ensure the precise alignment between the upper mold and the lower mold, and to guarantee the sealing and consistency of the mold cavity during injection molding.

[0019] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0026] like Figures 1-5 As shown, a dual-station wrist strap tensioning and coating turntable device includes a machine base 1. The machine base 1 is equipped with a turntable assembly 3 and two wrist strap coating lower mold assemblies 2 symmetrically arranged on the front and rear sides of the upper surface of the turntable assembly 3. Each wrist strap coating lower mold assembly 2 includes a lower mold 21, an injection molding inner mold 22 disposed within the lower mold 21, and wrist strap tensioning components 23 symmetrically arranged at both ends of the lower mold 21. Each wrist strap tensioning component 23 includes a tensioning positioning plate 231 and tensioning members symmetrically arranged on both sides of the bottom end of the tensioning positioning plate 231. The cylinder 232 has two symmetrically arranged tension sliding grooves 2311 on the tensioning positioning plate 231. The output end of the tensioning cylinder 232 is provided with a wrist rope positioning post 2321, which is slidably engaged in the tension sliding groove 2311. The middle of the injection molding inner film 22 is provided with an injection channel 221. Wrist rope fixing structures 222 are symmetrically arranged on both sides of the injection channel 221. Each wrist rope fixing structure 222 is provided with a rubber-coating groove 223 at the connection between it and the injection channel 221.

[0027] The turntable assembly 3 includes a turntable motor 31 and a processing turntable 32. The processing turntable 32 is located at the output end of the turntable motor 31. A circular baffle 11 is arranged around the processing turntable 32 on the machine base 1, and a stroke sensor 111 is arranged on the circular baffle 11.

[0028] Both sides of the coating groove 223 are provided with semi-circular platform openings 2231 for positioning the wrist rope welding part that needs to be coated.

[0029] At least one lifting hole 2232 is provided in the overmolding groove 223. The lifting hole 2232 penetrates the injection molding inner mold 22. A lifting cylinder is provided at the bottom of the lower mold 21. A plurality of lifting columns are connected to the output end of the lifting cylinder. Each lifting column is slidably fitted in one of the lifting holes 2232 for lifting the injection-molded wrist strap overmolding part.

[0030] Both sides of the wrist strap fixing structure 222 are equipped with wrist strap limiting blocks 2221.

[0031] The lower mold 21 is provided with upper mold mating holes 211 at its four corners, which are used to position the upper mold positioning posts located at the four corners at the lower end of the external movable upper mold assembly.

[0032] In summary, the specific implementation of this utility model is as follows: First, the inner injection mold 22 of the wrist rope coating lower mold assembly 2 located at the wrist rope input station receives four wrist ropes to be coated from the transfer robot. The two sides of the welded part of the wrist rope are placed on the wrist rope fixing structure 222 of the inner injection mold 22 by the robot and are coordinated with the wrist rope limiting blocks 2221 located on both sides of the wrist rope fixing structure 222 for limiting. The wrist ropes at both ends of the welded part are fixed on the semi-circular platform openings 2231 on both sides of the coating groove 223. The other end of the wrist rope is placed at one end of the wrist rope positioning post 2321.

[0033] Subsequently, the wrist cord tensioning component 23 pushes the wrist cord positioning post 2321 to slide along the tensioning sliding groove 2311 through the tensioning cylinder 232, thereby firmly tightening and fixing both ends of the wrist cord between the wrist cord positioning post 2321 and the wrist cord fixing structure 222.

[0034] Next, the turntable motor 31 drives the processing turntable 32, causing the lower mold assembly 2 located at the wrist strap input station to rotate to the coating station. The externally movable upper mold assembly descends, and the upper mold positioning pins at its four corners align with the upper mold mating holes 211 at the four corners of the lower mold 21, ensuring precise alignment between the upper and lower molds and forming a closed cavity. Then, the molten rubber material is injected into the cavity through the injection channel 221 to achieve the molding of the wrist strap coating part.

[0035] After injection molding is completed, the externally movable upper mold assembly detaches from the lower mold and rises. The turntable motor 31 drives the processing turntable 32 to rotate again, causing the lower mold assembly 2 located at the overmolding station to rotate back to the wrist strap input station. The lifting cylinder drives the lifting column to slide into the lifting hole 2232 that penetrates the injection molding inner mold 22, pushing out the newly formed wrist strap overmolding part. The robot arm transfers the wrist strap that has completed the overmolding operation to the next automated device for subsequent processing.

[0036] The above description is only the optimal solution embodiment of this utility model and is not intended to limit this utility model. Various modifications or substitutions made by those skilled in the art to this utility model without departing from the essence and protection scope of this utility model should also be within the protection scope of this utility model.
