[0003] Therefore, a kind of injection mold cleaning structure is needed urgently to solve the above problems. Utility Model Content

[0034] The present utility model will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the sake of description, only parts related to the present utility model are shown in the drawings, rather than all structures.

In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.
[0038] After the injection molded product is taken out, there may be residual materials such as flash at the cavity of the fixed mold, the cavity of the moving mold and the injection port of the moving mold. If the residual materials are not cleaned in time, it will affect the injection molding of subsequent products. At present, the residual materials are mostly cleaned manually, and the whole process requires workers to overcome a high temperature of over 200 °C, resulting in a low efficiency of the whole cleaning process and further reducing the injection molding efficiency of subsequent products. For this reason, an injection mold cleaning structure is proposed in this embodiment, which uses an automated device to clean the residual materials on the mold to increase the cleaning efficiency of the residual materials.
[0039] Specifically, please refer to Figure 1 and Figure 2 The injection mold cleaning structure includes a bracket 1, an air knife 2, a brush 3 and a moving mechanism 4. The air knife 2 is arranged on the bracket 1 and is used for blowing air at the residual materials; the brush 3 is arranged on the bracket 1 and is on one side of the air knife 2, and the brush 3 is used for brushing the residual materials; the moving mechanism 4 is connected to the bracket 1 and can drive the bracket 1 to move along a preset direction so that the air knife 2 and the brush 3 pass by the residual materials in sequence.
[0040] It can be understood that under the action of the moving mechanism 4, the wind knife 2 and the brush 3 can pass through the residual material in turn. The wind knife 2 blows air to the residual material, which can not only sweep away the lighter residual material, but also reduce the temperature of the residual material, thereby hardening it, so that the subsequent brush 3 can clean the residual material. Compared with manual removal of residual materials, the injection mold cleaning structure proposed in this embodiment has a low degree of manual participation, thereby avoiding the influence of high temperature environment on the cleaning process, and thus improving the cleaning efficiency of residual materials.
[0041] The moving mechanism 4 is preferably a six-axis manipulator, and the bracket 1 is arranged at the moving end of the six-axis manipulator. Under the action of the six-axis manipulator, the bracket 1 can be driven to move between the fixed mold and the movable mold, so that the wind knife 2 and the brush 3 can clean the residual materials. When the six-axis manipulator is used to drive the bracket 1 to move, the six-axis manipulator is outside the fixed mold and the movable mold, so as to reduce the influence of the high temperature environment on the moving mechanism 4.
[0042] There may be residual materials left in the cavity of the fixed mold, the cavity of the movable mold and the injection port of the movable mold. Therefore, the brush 3 needs to clean the residual materials in different parts according to different working conditions. For this reason, in this embodiment, the injection mold cleaning structure also includes a yaw mechanism 5, which is arranged on the bracket 1 and is connected to the brush 3 in a transmission manner to adjust the brush 3 to swing to a position in contact with the residual materials. That is, when it is necessary to clean the residual materials in the cavity of the fixed mold, the yaw mechanism 5 can control the brush 3 to swing in the direction close to the fixed mold cavity. When it is necessary to clean the residual materials in the cavity of the movable mold, the yaw mechanism 5 can control the brush 3 to swing in the direction close to the cavity of the movable mold. When it is necessary to clean the residual materials in the injection port of the movable mold, the yaw mechanism 5 can control the brush 3 to swing in the direction close to the injection port.
[0043] Specifically, the deflection mechanism 5 includes an extension 51, a swinging member 52 and a driving member 53. The extension 51 is arranged on the side of the bracket 1 away from the moving mechanism 4; the swinging member 52 is rotatably connected to the extension 51, and the brush 3 is detachably arranged on the swinging member 52; the driving member 53 is arranged on the extension 51 and is transmission-connected with the swinging member 52. It can be understood that under the action of the extension 51, the brush 3 can be placed outside the bracket 1 to avoid interference between the brush 3 and the bracket 1 during the swinging process; according to different working conditions, the driving member 53 can drive the swinging member 52 to deflect, thereby driving the brush 3 to deflect, and thus improving the applicability of the injection mold cleaning structure.
[0044] The detachable manner may be screw connection, clamp connection, etc., so as to facilitate the replacement of the model and type of the brush 3.
[0045] The driving member 53 is a rotating motor. The rotating motor is arranged on the extension member 51, and the rotating end of the rotating motor penetrates through the extension member 51 and is fixedly connected to the swinging member 52. It can be understood that when the rotating end of the rotating member penetrates through the extension member 51, the extension member 51 can support the rotating end of the rotating member, so as to avoid excessive load on the rotating end of the rotating member and improve the safety of the cleaning structure of the injection mold.
[0046] Exemplarily, the brush 3 is a roller brush 3. The roller brush 3 is rotatably connected to the swinging member 52, and the length direction of the roller brush 3 is perpendicular to the preset direction. It can be understood that under the action of the moving mechanism 4, the roller brush 3 can be driven to rotate around its own axis, so that it can contact the cavity surface from multiple angles, which is not only easier to clean the residual materials in hidden places, but also can increase the contact surface between the bristles and the cavity surface to improve the cleaning effect.
[0047] In addition, the length of the roller brush 3 is not less than the width of the cavity, so as to ensure that during the movement of the bracket 1, the roller brush 3 can contact all parts of the cavity surface, so as to further improve the cleaning efficiency of the residual materials.
[0048] Along the length direction of the extension member, a plurality of threaded holes are provided on the extension member; the yaw mechanism 5 further includes bolts (not shown in the figure), and the bolts are screwed into the threaded holes and fixedly connected to the bracket 1. Through the cooperation of the bolts and the threaded holes, it is convenient to install the extension member. In addition, the number of threaded holes is more than the number of bolts, so as to facilitate the adjustment of the position of the extension member, so that the position of the roller brush 3 can be adjusted, and thus the applicability of the cleaning structure of the injection mold can be improved.
[0049] Exemplarily, the extension member 51 includes two extension plates, which are respectively arranged on both sides of the bracket 1. The swinging member 52 includes two swing arms, which are respectively rotatably arranged on the two extension plates. The roller brush 3 is rotatably arranged between the two swing arms. Among them, the rotating motor is arranged between the extension plate and the swing arm.
[0050] In this embodiment, the air knife 2 has two air blowing ports, and the two air blowing ports are respectively directed towards the fixed mold and the moving mold. During the movement of the bracket 1 between the fixed mold and the moving mold, the two air blowing ports can blow air to the fixed mold and the moving mold at the same time, so as to cool the residual materials on the cavity surfaces of the fixed mold and the moving mold at the same time, so as to facilitate the subsequent brushing of the residual materials by the brush 3.
[0051] Furthermore, the air knife 2 is detachably arranged on the bracket 1, so as to select a suitable type of air knife according to needs. Among them, the detachable method can be screw connection, snap connection, etc., which will not be elaborated here.
[0052] When the air source supplies air to the air knife 2, it is mostly connected to the hose through an air joint, so as to be able to transport gas to the air knife 2. The hose is prone to softening and sagging under high-temperature environments, resulting in the adhesion of the hose to the fixed mold, and further affecting the injection molding efficiency of subsequent products. Therefore, in this embodiment, an air supply pipeline for transporting gas is provided inside the bracket 1. One end of the air supply pipeline is connected to an external air source, and the other end is connected to the air inlet of the air knife 2. The air supply pipeline arranged inside the housing can replace the hose to transport gas to the air knife 2, thus avoiding the phenomenon of softening in a high-temperature environment.
[0053] Furthermore, an air supply port communicating with the air supply pipeline is provided on the bracket 1, and the air supply port is hermetically docked with the air inlet. By directly docking the air supply port with the air inlet, the arrangement of the air joint can be reduced, so as to further reduce the mold opening height.
[0054] Based on the above, a product picking device is also proposed in this embodiment, which includes a clamping structure 100 and the injection mold cleaning structure as described above; the clamping structure 100 is arranged on one side of the air knife 2 and is used for clamping the molded product; the clamping structure 100 is arranged on the bracket 1, and when the bracket 1 moves along a preset direction, the clamping structure 100, the air knife 2 and the brush 3 sequentially pass through the residual material. Among them, the clamping device is preferably a finger clamping cylinder.
[0055] It can be understood that after the clamping device clamps the molded product, under the action of the moving mechanism 4, the bracket 1 can be moved out of the mold. During this process, the clamping structure 100, the air knife 2 and the brush 3 sequentially pass through the residual material, so that the residual material can be cleaned while the product is being moved out, thereby improving the injection molding efficiency of subsequent products.
[0056] Obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
