[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, this utility model provides a hardware stamping die with automatic cleaning function, including a die body 1. The die body 1 is provided with a multi-functional cleaning component 2. The multi-functional cleaning component 2 includes a rotating spray bar 201, a telescopic spray nozzle 202, a dual-degree-of-freedom drive mechanism 3, and a control module 101 that controls the cleaning path according to a preset program. The edge of the die body 1 is provided with an annular liquid collection tank, and the liquid collection tank is connected to an external recycling tank 103 through a filter pipe 102.

[0025] After the mold completes one stamping operation, the position sensor of the control module 101 detects in real time that the upper mold is in the preset mold opening position and transmits the signal to the path planning unit. The path planning unit plans a comprehensive and efficient cleaning path based on the specific structure of the mold cavity and sends the path information to the linkage controller.

[0026] The rotating spray bar 201 is rotatably mounted in the inner cavity of the upper mold via a bearing structure. The telescopic nozzle 202 is distributed along the axial direction of the rotating spray bar 201 and can extend and retract radially. The end of the telescopic nozzle 202 is provided with an atomizing nozzle 205.

[0027] The control module 101 is connected to the dual-degree-of-freedom drive mechanism 3 by signal. The dual-degree-of-freedom drive mechanism 3 includes a rotary motor 301 and a linear cylinder 302, which respectively drive the rotary spray bar 201 to rotate circumferentially and the telescopic nozzle 202 to extend and retract radially.

[0028] The linkage controller sends commands to the dual-degree-of-freedom drive mechanism 3. The rotary motor 301 drives the rotary spray bar 201 to rotate circumferentially, enabling the telescopic nozzle 202 to perform all-around cleaning of the mold cavity. The linear cylinder 302 controls the telescopic nozzle 202 to extend and retract radially. The inner sleeve 203, under the action of the return spring, cooperates with the outer sleeve 204 to realize the extension and retraction of the nozzle, so as to adapt to the cleaning needs of cavities of different depths. At the same time, the pressure pump 104 connected to the external recovery tank 103 works, and selects to connect to the cleaning agent storage tank or the clean water tank through the three-way valve, pressurizing the cleaning agent or clean water and delivering it to the rotary spray bar 201. The cleaning fluid is sprayed out through the atomizing nozzle 205 at the end of the telescopic nozzle 202. The spray direction of the atomizing nozzle 205 is at an adjustable angle of 30°-60° with the surface of the mold cavity, which can be adjusted according to the cleaning needs. The internal anti-clogging spiral guide plate 206 can effectively prevent impurities from clogging the nozzle, ensuring that the cleaning fluid is sprayed evenly and stably onto the surface of the mold cavity.

[0029] Waste liquid generated during the cleaning process flows into an annular collection tank at the edge of the lower mold. Magnetic filter 105 at the bottom of the collection tank adsorbs ferromagnetic impurities in the waste liquid, and oil-water separation layer 106 separates the waste liquid from oil. The filtered waste liquid flows to an external recovery tank 103 through filter pipe 102. A flow sensor in filter pipe 102 monitors the waste liquid flow rate in real time to ensure the normal operation of the recovery system.

[0030] After cleaning, the control module 101 controls the electric heating film 108 on the outer wall of the airtight isolation cover 107 to work, heating and drying the inside of the mold body 1 to prevent the mold from rusting due to moisture. The airtight isolation cover 107 ensures the sealing and efficiency of the heating and drying process.

[0031] Furthermore, the telescopic nozzle 202 includes an inner sleeve 203 and an outer sleeve 204, with a built-in return spring in the inner sleeve 203. The multi-functional cleaning assembly 2, through a dual-degree-of-freedom drive mechanism 3, enables the circumferential rotation of the rotating spray bar 201 and the radial extension and retraction of the telescopic nozzle 202. Combined with the optimal cleaning path planned by the path planning unit, it can perform all-round, thorough cleaning of the mold cavity.

[0032] The return spring design of the telescopic nozzle 202 ensures smooth and reliable telescopic movement; the anti-clogging spiral guide plate 206 of the atomizing nozzle 205 reduces the probability of nozzle clogging and lowers the equipment failure rate.

[0033] Furthermore, the spray direction of the atomizing nozzle 205 forms an adjustable angle of 30°-60° with the mold cavity surface, and the atomizing nozzle 205 is also equipped with an anti-clogging spiral guide plate 206. The adjustable spray angle and anti-clogging design of the atomizing nozzle 205 ensure that the cleaning fluid can accurately and evenly cover the cavity surface, effectively removing stains and impurities, improving cleaning quality and efficiency, and reducing the time and labor intensity of manual cleaning.

[0034] Furthermore, the control module 101 includes a position sensor for real-time detection of the upper mold opening position, a path planning unit, and a linkage controller. The recycling system, consisting of a collection tank, a filter pipeline 102, and an external recycling box 103, filters and recycles the cleaning waste liquid, realizing the recycling of the cleaning liquid and reducing the consumption cost of the cleaning liquid.

[0035] Furthermore, the bottom of the collection tank is equipped with a magnetic filter 105 and an oil-water separation layer 106, and a flow sensor is installed in the filter pipeline 102. The flow sensor facilitates monitoring of the operating status of the recovery system, ensuring recovery efficiency. The control module 101, through the coordinated operation of the position sensor, path planning unit, and linkage controller, achieves automated and intelligent control of the cleaning process, eliminating the need for manual intervention, thus improving the automation level of production and reducing human error.

[0036] Furthermore, the external recycling bin 103 is connected to a pressure pump 104, and the output of the pressure pump 104 is connected to a cleaning agent tank and a clean water tank respectively via a three-way valve. The three-way valve allows for the selection of cleaning agent or clean water for cleaning according to actual needs, and the adjustable spray angle of the atomizing nozzle 205 can also adapt to the cleaning requirements of different stains and cavity structures, enhancing the versatility and flexibility of the mold.

[0037] Furthermore, an airtight isolation cover 107 is provided between the interior of the mold body 1 and the rotating spray bar 201. An electrothermal film 108 is applied to the outer wall of the airtight isolation cover 107, and the electrothermal film 108 is connected to the control module 101. The cooperation of the airtight isolation cover 107 and the electrothermal film 108 allows for drying of the mold after cleaning, preventing rust and extending the mold's service life.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
