Description

Technical Field

[0001] The utility model relates to the technical field of mold processing and specifically discloses a mold processing device. Background Art

[0002] In the field of molds, the mold blowing structure plays a vital role. It ensures that the workpiece is evenly distributed in the mold cavity and promotes the cooling and demolding of the product. However, the traditional mold blowing structure has exposed a series of problems in practical applications, mainly focusing on the accuracy and stability of airflow control. The design of the traditional mold blowing structure is to connect the air pipe directly to the blowing joint. Once the blowing is turned on, the airflow will continue until the operator manually turns it off. This design has obvious defects, that is, the airflow cannot be adjusted automatically, resulting in continuous blowing during the mold closing process, causing airflow backflow. Airflow backflow not only causes energy waste, but also may cause the waste in the mold to be blown by the airflow, jumping up and crushing the product being formed. In severe cases, it may even damage the mold, affect product quality, increase production costs, and continuous airflow will also cause noise pollution, which has an adverse effect on the working environment.

[0003] Patent application number CN202323487253.X is a passive liftable blowing device installed in the hot stamping die cavity, including a blowing copper tube protective cover, a blowing copper tube, a copper tube connecting block, a limit screw and a reset spring. During stamping, the upper die base body compresses the reset spring by pushing the blowing copper tube protective cover, so that the blowing device composed of the blowing copper tube protective cover, the blowing copper tube and the copper tube connecting block moves downward during the stamping process, ensuring that the blowing copper tube is not damaged while not affecting the stamping. After one stamping is completed, the reset spring rebounds to raise the blowing device and perform the blowing and slag removal work. The limit screw is debugged to a suitable length during installation, and an appropriate reset spring is selected accordingly, so that the blowing copper tube can be located at the best blowing position after the reset spring rebounds, so as to achieve a better cleaning function. The above device is not easy to disassemble, and the overall replacement and maintenance cost is high when the parts are damaged. Therefore, it is urgent for technicians in this field to solve the above technical problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is that in the above-mentioned prior art, after the mold waste blowing cleaning structure starts to blow air, the blowing is continuous and it is easy to cause air flow backflow to generate waste.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A mold processing device comprises a base, a template box, an air inlet, a template air groove, an air outlet, a floating pin, a reset member and a positioning member; the positioning member, the reset member and the floating pin are sequentially arranged inside the base, and an air hole is arranged on the upper part of the base; the reset member is fixed inside the base through the positioning member, the reset member assists the floating pin to return to the initial spatial position, and the floating pin is arranged on an alignment hole; the template box is arranged above the base, the air outlet is arranged on the upper part of the template box, the template air groove is arranged inside the template box, the air inlet is arranged at the bottom of the template box, the template air groove is connected to the air outlet and the air inlet respectively, and the air inlet is aligned with the floating pin in the vertical direction.

[0007] Furthermore, the reset member is an elastic member, the bottom of the reset member is fixed on the positioning member, and the floating pin is fixed on the upper part of the reset member.

[0008] The presence of the reset part enables the lifting pin to be accurately aligned with the air hole of the template. Only when the upper and lower molds are tightly fitted can the air flow pass, ensuring the accuracy of blowing and avoiding disordered flow of air. Since the blowing starts when the upper and lower molds are completely closed, it effectively prevents the jumping of waste and avoids the situation where the product is crushed, thereby improving product quality and eliminating potential risks in the production process. By controlling the blowing time, the noise generated by continuous blowing is avoided, creating a quieter working environment and reducing the hearing impact on the operator.

[0009] Furthermore, the resetting element is a spring or a rubber airbag.

[0010] The elastic properties of the spring or rubber airbag enable the lifting pin to be accurately aligned with the air hole of the template when the upper and lower molds are closed, ensuring that blowing is performed only when needed, avoiding continuous flow of airflow, reducing the bouncing of waste materials and damage to products. By controlling the timing of blowing, product crushing caused by air backflow and waste bouncing is avoided, thereby eliminating quality risks in the production process and improving production safety. The use of springs or rubber airbags can effectively slow down the pressure release speed during blowing, thereby reducing the noise level generated by blowing, improving the working environment, and reducing the impact of noise on operators. The reset part quickly returns to its original state after the blowing is completed, making the blowing process fast and accurate, and improving production efficiency.

[0011] Furthermore, the floating pin is opened at the top and the bottom and is a hollow structure, the upper part of the floating pin is provided with the alignment hole, and the aperture of the alignment hole is consistent with the aperture of the air hole.

[0012] The hollow structure ensures that the airflow can pass through the floating pin smoothly, and the design of the alignment hole ensures that the airflow will only flow when the upper and lower molds are completely closed and the alignment holes of the floating pin are precisely aligned with the air holes of the template. This avoids the airflow backflow and waste jumping caused by continuous blowing, thereby protecting product quality and eliminating quality risks in production. Since the blowing process is precisely controlled, unnecessary continuous blowing is avoided, which significantly reduces the noise during the blowing process and improves the working environment. Through precise management of the airflow, the cleaning and adjustment time required due to waste jumping is reduced, and the operation efficiency and overall production efficiency of the mold are improved. Since the airflow backflow and abnormal impact of waste on the mold are avoided, the wear of the mold and related equipment is reduced and the service life of the equipment is extended. The automated blowing control mechanism reduces manual intervention, simplifies the operating process, reduces production costs, avoids the risk of accidental injury caused by waste jumping, and enhances the safety of the production process.

[0013] Furthermore, the positioning member is a positioning screw, the positioning member is installed inside the bottom, and the positioning member is aligned with the air inlet.

[0014] The positioning screw can accurately fix the position of the floating pin and ensure that its air hole is accurately aligned with the air hole of the template, so that the blowing process is more accurate and controllable. The use of the positioning screw can make the floating pin remain stable even when the upper and lower molds are tightly closed, avoiding the blowing effect due to position offset. By controlling the alignment of the floating pin and the air hole of the template, it can effectively prevent the air flow from flowing back during blowing, reduce the risk of waste jumping and product crushing, and improve product quality. The positioning screw ensures the stability of the blowing structure, reduces unnecessary vibration, and helps to reduce noise during the blowing process. The positioning screw is easy to disassemble and reposition, so that the position of the floating pin can be fine-tuned as needed, simplifying the maintenance process. By accurately controlling the blowing timing and avoiding quality problems, the positioning screw indirectly improves production efficiency and reduces production interruptions caused by increased scrap rates.

[0015] The utility model has the following beneficial effects:

[0016] 1. Through the precise alignment of the floating pin and the air hole of the template, it is ensured that the blowing is started only when the upper and lower molds are completely closed. This design effectively avoids the backflow of airflow and prevents the abnormal jumping of waste under the action of airflow, thereby avoiding the presence of chips on the surface of the product and being crushed, reducing the quality risks in the production process;

[0017] 2. By controlling the opening time of the blowing, unnecessary continuous blowing is reduced, thereby reducing the continuous noise generated during the continuous blowing process. This not only improves the working environment, but also helps to improve the acoustic comfort of the production area, meeting the requirements of modern factories for environmental protection and occupational health;

[0018] 3. Through the coordination of the lifting pin and the template air hole, the blowing process is precisely controlled, which not only avoids production stagnation caused by improper blowing, but also reduces the time required for waste disposal and product repair, thereby improving overall production efficiency. At the same time, the improved blowing structure significantly reduces the probability of safety accidents, ensuring the stable operation of the production line and the safety of employees.

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.

[0024] In the description of the present invention, it should be understood that the terms "left side", "right side", "upper part", "lower part", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second", etc. do not indicate the importance of the components, and therefore cannot be understood as a limitation on the present invention. The specific dimensions used in this embodiment are only for illustrating the technical solution, and do not limit the scope of protection of the present invention.

[0025] Reference Figure 1 and Figure 2 It can be seen that a mold processing device includes a base 1 located at the bottom of the device, and a floating pin 13, a reset member 12 and a positioning member 11 are installed in the base 1 from top to bottom. Above the base 1 is a template box 3, and an air outlet 2 is installed above the template box 3. The air inlet 4 is connected to the template air groove 31 inside the template box 3, and the template air groove 31 is connected to the air outlet 2 below the template box 3, and the air outlet is aligned with the floating pin 13 on the base 1.

[0026] In one embodiment, the base 1 is the foundation of the entire device, and space needs to be reserved inside to install other components. The internal space of the base 1 is the installation position of the floating pin 13, the reset member 12 and the positioning member 11 from top to bottom. The positioning member 11 is the base point for fixing the reset member 12 and is usually installed at the bottom layer of the base 1. The positioning member 11 is fixed inside the base to ensure the stability of the position of the reset member 12. The reset member 12 is placed above the positioning member 11, and the bottom of the reset member 12 is fixedly connected to the positioning member 11. The main function of the reset member 12 is to provide a force for the floating pin 13 to return to its original position, ensuring that the floating pin 13 can return to its initial position when there is no pressure. The floating pin 13 is installed above the reset member 12 and is connected to the upper part of the reset member 12. The floating pin 13 has an alignment hole 131 for aligning with the air hole 14 of the base 1, so as to control the on and off of the airflow. The template box 3 is installed above the base 1, and contains a template air groove 31 inside. The template air groove 31 plays a role in guiding the airflow from the air inlet 4 to the air outlet 2. The air inlet 4 is installed at the lower part of the template box, and the air outlet 2 is arranged at the upper part of the template box 1. The air inlet 4 is directly opposite to the floating pin 13 on the base 1, ensuring that when the floating pin 13 is pressed down, the airflow can directly enter the air hole 14 of the base 1 through the alignment hole 131 of the floating pin 13;

[0027] When in use, the external air source is guided out from the air outlet 2 through the air inlet 4 via the template air groove 31 inside the template box 3. When the template box 3 is fitted with the base 1, the air inlet 4 is aligned with the air hole 14 on the base 1, and the base 1 blows air to the template box 3.

[0028] Reference Figure 3 It can be known that the positioning member 11 is a positioning screw, the positioning member 11 is fixed on the base 1, a reset member 12 is fixed on the positioning member 11, a floating pin 13 is fixed above the reset member 12, and the floating pin 13 is opened at the top and bottom and is a hollow structure.

[0029] In one embodiment, the reset member 12 is a spring, the bottom of the reset member 12 is welded to the positioning member 11, and a floating pin 13 is welded above the reset member 12. In the initial state of the reset member 12, the alignment hole 131 of the floating pin 13 is located above the air hole 14 on the base 1. When the template box 3 is fitted with the base 1, the reset member 12 is compressed under the pressure of the template box 3, and the floating pin 13 is completely immersed in the base 1. At this time, the alignment hole 131 is aligned with the air hole 14 in the base 1, and the air hole 14 of the base 1 sends the air flow into the template box 3 through the air inlet 4 to achieve blowing of the workpiece. After the blowing is completed, the template box 3 is lifted. At this time, the reset member 12 is reset under the action of its own elastic force, and the air hole 131 is staggered from the air hole 14. The air hole 14 cannot continue to blow toward the template box 3, thereby avoiding the problem of waste material jumping caused by the failure to stop blowing in time;

[0030] The reset member 12 can also be a rubber airbag, which is a cylindrical structure and is arranged above the positioning member 11. The two can be connected and fixed by an adhesive. A floating pin 13 is also connected and fixed above the rubber airbag. During operation, the template box 3 is pressed down, and the air inlet 4 is in contact with the base. The floating pin 13 is completely immersed in the base 1 under the pressure of the template box 3. The alignment hole 131 of the floating pin 13 is aligned with the air hole 14 of the base 1. The air hole of the base 1 continuously blows air into the template box 3 through an external air source. After the blowing is completed, the template box 3 is lifted, and the air inlet 4 is separated from the floating pin 13. The floating pin 13 returns to the initial position under the elastic action of the rubber airbag, and the alignment hole 131 is staggered with the air hole 14. The air hole 14 cannot continue to blow air to the template box 3, which also avoids the problem of waste caused by the inability to stop the blowing work.

[0031] The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical scheme of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
