Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to an automotive front bulkhead foaming mold holder device. Background Technology

[0002] In the existing production process of automotive front bulkhead foam molds, traditional techniques mainly rely on manual operation to open and close the molds. This method involves workers manually operating mechanical devices or directly applying force to the mold to complete processes such as filling, molding, and demolding of the foam material. Its advantages are as follows: manual operation is flexible and can adapt to the needs of small-batch, multi-variety production; operators can directly perceive the mold's condition through sight and touch, and adjust the operating force and angle in a timely manner; and the initial equipment investment cost is relatively low, making it suitable for small and medium-sized enterprises with limited funds.

[0003] However, existing technologies have gradually revealed the following technical problems: manual operation is labor-intensive, and long-term repetitive work can easily lead to worker fatigue and pose safety hazards; the opening and closing speed of the mold is limited by the efficiency of manual operation, making it difficult to meet the requirements of large-scale production cycle; the positioning accuracy of the mold depends on the experience of the operator, and deviations are prone to occur, resulting in fluctuations in the product qualification rate; the dispersion of processes leads to a longer production cycle, and labor costs increase linearly with the increase in output; and traditional molds lack safety protection devices, exposing operators to the vicinity of moving mechanical parts, posing a risk of pinching injuries. Utility Model Content

[0004] The purpose of this utility model is to provide a foaming mold holder for automotive front bulkheads, aiming to solve the following technical problems in the prior art: high labor intensity of manual operation, long-term repetitive work easily leads to worker fatigue and safety hazards; the opening and closing speed is limited by the efficiency of manual operation, making it difficult to meet the requirements of large-scale production cycle; the positioning accuracy of the mold depends on the experience of the operator, which is prone to deviation and leads to fluctuations in product qualification rate; the process is dispersed, which leads to a longer production cycle and labor costs increase linearly with the increase in output; and traditional molds lack safety protection devices, exposing operators to the vicinity of mechanical moving parts, posing a risk of pinching injury.

[0005] To achieve the above objectives, this utility model employs an automotive front bulkhead foaming mold frame device, comprising an upper frame, a loading template, and a base. The upper frame has a T-shaped groove at its top, two upper fixed arms at its front end, and a flipping arm at its rear end. The base has two lower fixed arms at its front end and two support seats at its rear end. Two lifting cylinders are mounted on the base, and opening and closing cylinders are hinged to both sides of the base. The two flipping arms are respectively hinged to their corresponding support seats and located on the two support seats. The two upper fixed arms respectively abut against their corresponding lower fixed arms. The loading template is hinged to its corresponding opening and closing cylinder and located at the output end of the two opening and closing cylinders. The loading template is fixedly connected to its corresponding lifting cylinder and located at the output end of the two lifting cylinders. The upper frame is located directly above the loading template.

[0006] The upper fixed arm has a locking pin at its lower part, and the lower fixed arm has a locking hook body hinged to its upper part, with the locking hook body abutting the locking pin.

[0007] The lower fixed arm is hinged to a locking hook cylinder on its outer side, and the locking hook body is also hinged to the locking hook cylinder and located at the output end of the locking hook cylinder.

[0008] The support base is equipped with a pin cylinder, and the output end of the pin cylinder is equipped with a pin body. Both the support base and the flipping arm have pin holes.

[0009] The automotive front bulkhead foaming mold frame device further includes multiple guide components, each guide component including a guide post and a guide cylinder. The guide post is fixedly connected to the carrier template and located below the carrier template. The guide post is also slidably disposed inside the guide cylinder. The guide cylinder is fixedly connected to the base and located on the base.

[0010] The base is also rotatably mounted with three connecting shafts, two of which are equipped with synchronous gears at both ends. A synchronous rack is provided on the outer side of the guide post, and the synchronous gears mesh with the synchronous rack. The three connecting shafts are connected by bevel gears.

[0011] This utility model discloses a foaming mold holder device for automotive front bulkheads. Through the opening and closing hydraulic cylinder and the lifting hydraulic cylinder, the mold is automatically opened, closed, and lifted, significantly reducing the labor intensity of workers and avoiding fatigue caused by long-term repetitive work. It also reduces the time workers spend exposed to moving mechanical parts, lowering the risk of pinching injuries. Furthermore, it improves the mold opening and closing speed to meet the requirements of large-scale production: the opening and closing time is reduced from 30 seconds manually to 20 seconds, significantly improving production efficiency. It also enhances mold positioning accuracy and reduces fluctuations in product qualification rate: the connection surface between the upper frame and the mold is milled to ensure a tight fit between the upper frame and the upper mold, and the support plate is made of thick steel plate. The surface is milled, ensuring a tight fit with the mold and reducing deviations caused by the reliance on operator experience for mold positioning accuracy, thus improving product qualification rate. The process is integrated, shortening the production cycle and reducing labor costs: foaming and front blanket punching are completed in one process, reducing the need for post-foaming punching, saving labor and the mold and equipment investment required for the original punching process. As production increases, labor costs no longer increase linearly. Safety features are enhanced: the device is equipped with a safety pin and pin cylinder. When the upper frame is opened to a 65-degree angle with the horizontal plane, the safety pin inserts into the pin hole to prevent the upper frame from falling, further ensuring operator safety.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] Please see Figures 1 to 7 This utility model provides a foaming mold frame device for automotive front bulkheads, including an upper frame 1, a template 2, and a base 3. The upper frame 1 has a T-shaped groove on its upper part. The front end of the upper frame 1 is provided with two upper fixed arms 5, and the rear end of the upper frame 1 is provided with a flipping arm 6. The front end of the base 3 is provided with two lower fixed arms 7, and the rear end of the base 3 is provided with two support seats 8. The base 3 is provided with two lifting cylinders 9, and both sides of the base 3 are hinged with opening and closing cylinders 10. The two flipping arms 6 are respectively hinged to the corresponding support seats 8 and located on the two support seats 8. The two upper fixed arms 5 respectively abut against the corresponding lower fixed arms 7. The template 2 is hinged to the corresponding opening and closing cylinder 10 and located at the output end of the two opening and closing cylinders 10. The template 2 is fixedly connected to the corresponding lifting cylinder 9 and located at the output end of the two lifting cylinders 9. The upper frame 1 is located directly above the template 2.

[0023] In this embodiment, by integrating the core components of the upper frame 1, the template 2, and the base 3, and by utilizing the opening and closing cylinder 10 and the lifting cylinder 9 to achieve automatic opening, closing, and lifting of the mold, the labor intensity of workers is significantly reduced, the opening and closing speed of the mold is increased, thereby improving production efficiency. At the same time, the T-slot design of the upper frame 1 facilitates the quick installation and fixation of the mold, ensuring the stability and efficiency of the production process.

[0024] Furthermore, a locking pin 11 is provided below the upper fixed arm 5, and a locking hook body 12 is hinged above the lower fixed arm 7, with the locking hook body 12 abutting against the locking pin 11.

[0025] In this embodiment, by attaching the locking hook body 12 to the locking pin 11, the mold is stably locked in the mold-closed state, which effectively prevents the mold from being accidentally opened during the production process, improves production safety, and ensures the positioning accuracy of the mold and the qualification rate of the product.

[0026] Furthermore, a locking hook cylinder 13 is hinged to the outer side of the lower fixed arm 7, and the locking hook body 12 is also hinged to the locking hook cylinder 13 and located at the output end of the locking hook cylinder 13.

[0027] In this embodiment, by hingedly connecting the locking hook cylinder 13 to the outside of the lower fixed arm 7 and hinged the locking hook body 12 to the locking hook cylinder 13, the automatic opening and closing of the locking hook body 12 is achieved.

[0028] Furthermore, a pin cylinder 14 is provided on the support base 8, and a pin body 15 is provided at the output end of the pin cylinder 14. Both the support base 8 and the flipping arm 6 have pin holes 16.

[0029] In this embodiment, by inserting the pin body 15 into the pin hole 16 on the support base 8 and the flip arm 6, the upper frame 1 is stably fixed when it is opened to a position of 65 degrees with the horizontal plane, which effectively prevents the upper frame 1 from falling accidentally, ensures the safety of the operator, and improves the stability and reliability of the equipment.

[0030] Furthermore, the automotive front bulkhead foaming mold frame device also includes multiple guide components, including guide posts 17 and guide cylinders 18. The guide posts 17 are fixedly connected to the carrier template 2 and located below the carrier template 2. The guide posts 17 are also slidably disposed within the guide cylinders 18. The guide cylinders 18 are fixedly connected to the base 3 and located on the base 3.

[0031] In this embodiment, the guide column 17 and the guide cylinder 18 ensure the stability and accuracy of the loading template 2 during the lifting process, reduce mold offset or damage caused by poor guidance, and improve production efficiency and product quality.

[0032] Furthermore, three connecting shafts 19 are rotatably arranged above the base 3, with synchronous gears 20 at both ends of two of the connecting shafts 19, and synchronous racks 21 arranged on the outer side of the guide post 17, and the synchronous gears 20 meshing with the synchronous racks 21. The three connecting shafts 19 are connected by bevel gears 4.

[0033] In this embodiment, the synchronization and stability of the lifting and lowering process of the loading template 2 are achieved through the three connecting shafts 19, the meshing of the synchronous gear 20 and the synchronous rack 21, and the connection of the bevel gear 4.

[0034] In this invention, during the mold opening and closing process, the opening and closing hydraulic cylinder 10 drives the upper frame 1 to rotate around the pivot on the support base 8, thereby realizing the flipping and opening of the upper mold. Meanwhile, the lifting hydraulic cylinder 9 drives the carrying plate 2 to move up and down to adjust the position of the lower mold, ensuring accurate mold closing. During mold closing, the locking pin 11 below the upper fixed arm 5 engages with the locking hook body 12 above the lower fixed arm 7. Driven by the locking hook cylinder 13, the locking hook body 12 automatically engages, ensuring stable locking of the mold in the closed state. During mold opening, the locking hook cylinder 13 reverses its direction, opening the locking hook body 12 and causing the upper frame 1 to flip upwards to the designated position. At this time, the support base 8... The pin cylinder 14 drives the pin body 15 to insert into the pin hole 16 aligned on the support base 8 and the flip arm 6, preventing the upper frame 1 from falling accidentally and ensuring the safety of the operator. At the same time, the lifting of the template 2 is controlled by the lifting cylinder 9, and the guide ensures the stability and accuracy of the lifting process. The three connecting shafts 19 above the base 3 achieve the synchronicity of the lifting of the template 2 through the meshing of the synchronous gear 20 and the synchronous rack 21 and the connection of the bevel gear 4, further improving the opening and closing accuracy of the mold. The entire working process is precisely controlled by the PLC control system, realizing the automation of actions such as mold opening, mold closing, and punching.

[0035] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
