[0003] The existing round fingerprint lock has a structure consisting of a housing, a lock core, a lock tongue, etc. The housing is mainly made by stamping.

[0004] However, it was found during the production process that it was inconvenient to demold the shell, that is, after each stamping was completed, workers were required to use tools to remove the stamped shell from the cavity. At this time, if the stamping mold was pressed, production accidents were very likely to occur. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figures 1 to 3 The circular fingerprint lock processing device shown in the figure includes a bottom plate 100 and a top plate 400, wherein the top plates are arranged vertically and in parallel. Four guide pillars 200 are arranged at four corners between the bottom plate and the top plate to connect the top plates together. At the same time, a first telescopic cylinder 500 is fixedly installed above the top plate, and the first telescopic cylinder is arranged vertically, and the telescopic rod of the first telescopic cylinder can be telescopically arranged through the top plate. In addition, as Figure 1As shown, a movable template 300 is also arranged between the top plate and the top plate, and the movable template is fixedly connected to the end of the telescopic rod of the first telescopic cylinder so as to be lifted up and down under the drive of the first telescopic cylinder. In addition, four guide pillars are also arranged to slide through the four corners of the movable template to guide the lifting of the movable template. It should be noted that in this scheme, a movable mold core 600 is also installed on the lower surface of the movable template, and the movable mold core is adapted to the shape of the inner cavity of the shell so that after the plate is stamped, the plate can be formed into the inner cavity of the shell. In contrast, a static mold core 1100 is fixedly installed on the bottom plate, and the shape of the static mold core is the same as the outer shape of the shell so that after the plate is pressed, its outer surface can be formed into a corresponding shape. In addition, it should be noted that in this scheme, in order to enable the molded shell to be self-demolded, the worker can reduce the step of blowing the shell out of the static mold core with a high-pressure air gun. A groove is also opened in the bottom plate 100, and a second telescopic cylinder 1200 is installed in the groove. It should be noted that if Figure 3 As shown, the telescopic rod of the second telescopic cylinder is inserted into the static mold core in a sliding fit, and extends out when the molded shell needs to be demolded, so as to lift the shell and break away from the contact with the static mold core. It should be noted that in this way, even if the shell is lifted, it still does not fall out of the mold. For this reason, the following auxiliary structure is also provided in this scheme.

[0024] like Figure 2 , Figure 3 As shown, a steam inlet channel 1120 and at least one air outlet channel 1110 are also provided in the static mold core, wherein the air outlet ports of the air outlet channel are arranged on the cavity surface of the static mold core, and an air pump 1000 is connected to the air inlet end of the air inlet channel, and the air pump can generate high-pressure gas so that when the air inlet channel is connected to the air outlet channel, the gas is blown into the cavity of the static mold core. It should be noted that in order to prevent the blowing of gas during the molding process, the air inlet channel and the air outlet channel are not connected before the telescopic rod of the second telescopic cylinder is extended to lift the shell. When the telescopic cylinder of the second telescopic cylinder is extended and the shell is lifted away from the static mold core, the connection between the air inlet channel and the air outlet channel is guaranteed. In order to realize the above functions, a transfer channel 1210 is also provided on the telescopic rod of the second telescopic cylinder. Specifically, when the telescopic rod of the second telescopic cylinder is in the initial position, the transfer channel is in a misaligned state with the air inlet channel and the air outlet channel, and when the telescopic rod of the second telescopic cylinder is extended, the two ends of the transfer channel are respectively connected to the air inlet channel and the air outlet channel to achieve the connection between the air inlet channel and the air outlet channel. At this time, the high-pressure gas generated by the air pump can be sprayed into the static mold core through the air outlet channel, and the shell lifted by the telescopic rod is blown out of the mold cavity of the static mold core.

[0025] It should be noted that in the above method, in order to keep the ejection direction of the blown shell consistent, at least one outlet channel opened on the static mold core is concentrated on one side. And the spacing between adjacent outlet channels is kept equal, so that the shell is evenly stressed. As a preferred embodiment of the above method, these outlet channels are preferably distributed in an annular surface with an angle of 120°.

[0026] In addition, it should be noted that in rare cases, the following situation may occur, that is, the shell of the cavity blown out of the static mold core falls on the parting surface of the static mold core. In this case, workers are usually required to manually remove the shell. However, manual removal is very dangerous, and workers' hands can easily be crushed. For this reason, a method is designed that can perform a push-sweep operation on the surface of the static mold core after the dynamic mold core is raised and the air pump blows out the shell. This will effectively avoid the above-mentioned shell falling on the inlet mold core and requiring workers to pick it up. Specifically, if Figure 1 As shown, a rotary cylinder 800 is installed beside the static mold core, and a push plate 900 is connected to the rotating end of the rotary cylinder. The lower edge of the push plate is slightly higher than the upper surface of the feed mold core, so that when the rotary cylinder rotates, the push plate can be driven to sweep over the upper surface of the feed mold core, and avoid the push plate from contacting the static mold core and causing damage to the static mold core. It should be noted that in order to realize the automatic sweeping of the push plate after the stamping is completed, a switch mechanism 700 for controlling the action of the rotary cylinder is also provided in the present solution. The switch mechanism can send a command to the rotary cylinder to drive it to rotate after the dynamic mold core is stamped and raised.

[0027] It should be noted that there are many structures of the switch mechanism 700 that realizes the above functions. In this embodiment, the specific implementation scheme is as follows: the switch mechanism specifically includes two groups of toggle components, namely, the wave component A710 and the toggle component B720. It should be noted that the toggle component A and the toggle component B have the same structure and are centrally symmetrically distributed so that they can be staggered when misaligned. At the same time, it also includes a pull-type switch 730, which is installed on the toggle component B, so that when misaligned, the toggle component A can drive the toggle component B upward, and pull the pull-type switch by the way, so that it sends a rotation signal to the rotating cylinder electrically connected thereto. It should be noted that in this solution, the specific structure of the toggle component A and the toggle component B is to include a limit plate 714, which is fixedly connected to the support. Specifically, the limit plate of the toggle component A is fixedly installed on the movable mold core, and the limit plate of the toggle component B is fixedly installed on the guide column. At the same time, a support 715 is provided on the upper surface of the limit plate, on which a rotating shaft 712 is rotatably mounted, and a tongue plate 711 extending horizontally to the outside of the limit plate is connected to the rotating shaft. It should be noted that because the end of the limit plate is located on the lower surface of the tongue plate, the tongue plate can only be flipped upwards but not downwards, that is, when the tongue plates in the toggle assembly A and the toggle assembly B in this scheme are misaligned, only the tongue plate in one of the components can be flipped. Specifically, the toggle assembly A installed on the movable mold core can be flipped upwards when it is misaligned with the wave assembly B during the process of following the movable mold core to descend and punch, so as to ensure the smooth descent of the movable mold core. When the movable mold core rises, the tongue plate in the toggle assembly B flips upwards under the lifting of the tongue plate in the wave assembly A, and at this time, the pull-type switch connected to the tongue plate of the wave assembly B is also pulled immediately, thereby realizing the accurate issuance of the driving signal of the rotary cylinder and driving the rotary cylinder to rotate in time. It should be noted that in the above scheme, in order to prevent the tongue plate from being unable to return to its original position after turning up, a spring 713 is also installed on the rotating shaft. The spring is in a torsion state to apply a force to the rotating shaft tending to rotate it downward, thereby ensuring that the tongue plate can always remain horizontal and abut against the limit plate after being free from external influences.

[0028] Working principle: When it is necessary to process and stamp the round fingerprint lock, the staff will place the plate between the dynamic mold core and the static mold core, and then drive the first telescopic cylinder to extend so that the dynamic mold core is pressed into the static mold core to complete the stamping of the round fingerprint lock shell. When the stamping of the shell is completed, the first telescopic cylinder retracts so that the dynamic mold core exits the static mold core. Then, the telescopic rod of the second telescopic cylinder extends to push the stamped shell that is still trapped in the static mold core cavity out of the static mold core cavity. In addition, it should be noted that when the second telescopic cylinder extends, the transfer channel opened on the telescopic rod of the second telescopic cylinder is docked with the air inlet channel and the air outlet channel opened in the static mold core. After the high-pressure gas generated by the air pump connected to the air inlet channel is connected to the air outlet channel, it is sprayed into the static mold core through the air outlet channel, and an impact force is applied to the shell lifted by the second telescopic cylinder, and the shell is then blown out of the static mold core by the high-pressure gas. It should be noted that in order to prevent the very few shells that fall on the parting surface of the static mold core from hindering the continuous implementation of stamping, during the process of the dynamic model rising, the switch mechanism will also drive the rotary cylinder to move synchronously, that is, after the shell is blown out by the high-pressure gas, the rotary cylinder will move and drive the push plate to implement a push sweep on the surface of the static mold core, pushing away the very few shells that fall on the surface of the static mold core, thereby effectively ensuring the continuous implementation of stamping. It should be noted that this solution realizes the automatic demolding of the shell after the stamping is completed through the above form, reduces the steps of manual operation, and greatly improves the stamping efficiency and the safety of workers in the production process.
