Description

Technical Field

[0001] This utility model relates to the technical field of mold spraying processing, and in particular to a closed multi-angle mold spraying device. Background Technology

[0002] In order to enable molds to form products with textured surfaces, current molds are manufactured by etching to create raised and recessed textures on the surface of the mold cavity.

[0003] Currently, the commonly used mold coating equipment in the industry has the following shortcomings: Single spraying angle and poor coating uniformity: Traditional spraying devices mostly use fixed spray heads or manual hand-held spray guns. The spray head can only move in a single direction or within a small range of angles. Molds often have complex curved surfaces, grooves and other structures. Spraying at a fixed angle is difficult to cover all surfaces of the mold, which can easily lead to problems such as missed spraying and uneven coating thickness, directly affecting the performance and service life of the mold. Open-plan operation poses significant environmental pollution and safety hazards: Most spraying equipment lacks an effective enclosure structure, allowing paint mist and volatile organic compounds (VOCs) generated during the spraying process to diffuse directly into the workshop environment. This not only causes air pollution in the workshop but can also be inhaled by operators, endangering their health. At the same time, open-plan operation can easily lead to dust and other impurities adhering to the undried coating surface, affecting the quality of the spraying. Insufficient mold positioning and fixing stability: Traditional equipment often uses simple clamps or bolts to fix molds, which makes it difficult to make flexible adjustments according to molds of different sizes and shapes. Molds are prone to displacement or shaking during the spraying process. In addition, "blind spots" are prone to appear at the contact points between the clamps and the mold, which means that the area cannot be sprayed and requires manual respraying, increasing the process cost.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a closed multi-angle mold spraying device, which would make it more valuable for industrial use. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a closed multi-angle mold spraying device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A closed multi-angle mold spraying device includes an equipment frame, an equipment support, a spraying unit, and a tooling unit. The equipment frame is mounted on the equipment support, and several support feet are installed at the bottom of the equipment support. The spraying unit and the tooling unit are both mounted on the equipment frame. An outer frame is installed on the equipment rack outside the spraying unit and tooling unit. A liftable enclosed door is installed at the front end of the outer frame, and viewing windows are installed on both the left and right sides of the outer frame. The spraying unit includes a support base mounted on the equipment frame, a first longitudinal mounting rod mounted on the support base, a cylinder mounting base mounted on the first longitudinal mounting rod via the first longitudinal mounting base, a spraying push-pull cylinder mounted on the cylinder mounting base, the spraying push-pull cylinder driving the second longitudinal mounting rod to move in the left and right direction, and the spraying head mounted on the second longitudinal mounting rod via the second longitudinal mounting base. The tooling unit includes a tooling support frame mounted on the equipment frame. A tooling top seat is mounted on the top of the tooling support frame. A servo motor mounted on one side of the bottom of the tooling top seat is connected to a turntable on the other side via a synchronous belt module. A gripper mounting seat is mounted on the side of the turntable above the tooling top seat. Several gripper cylinders are mounted at the bottom of the gripper mounting seat. Grippers adapted to the aforementioned gripper cylinders are mounted above the gripper mounting seat.

[0007] As a further improvement of this utility model, a control box and an operating console are installed on one side of the outer frame of the equipment.

[0008] As a further improvement of this utility model, a door lifting cylinder is installed on the top side of the outer frame of the equipment, and the piston rod at the bottom of the door lifting cylinder is connected to the door through a lifting connecting block.

[0009] As a further improvement of this utility model, a top cover is also installed on the top of the outer frame of the equipment, and a suction pipe connected to an external suction fan is installed on the top of the top cover.

[0010] As a further improvement of this utility model, infeed and discharge sensors are installed on the outer frame of the equipment on both sides of the front end of the closed door.

[0011] As a further improvement of this utility model, the bottom of the second longitudinal mounting rod is mounted on the spraying slider, and the piston rod of the spraying push-pull cylinder drives the spraying slider to move left and right within the cylinder mounting seat.

[0012] As a further improvement of this utility model, the spraying slider is connected to the spraying guide rail installed in the cylinder mounting base, and a spraying limiting post is installed on the side of the cylinder mounting base away from the spraying push-pull cylinder.

[0013] As a further improvement of this utility model, a baffle is installed on the turntable below the gripper mounting base.

[0014] As a further improvement of this utility model, a flexible contact block is installed on the contact end inside the gripper.

[0015] By means of the above solution, this utility model has at least the following advantages: The spraying unit of this invention uses a spraying push-pull cylinder to drive the spraying head to move flexibly in the left and right directions. At the same time, the turntable of the tooling unit drives the mold to rotate under the drive of a servo motor. The combined effect of the two allows the spraying head to perform full-coverage spraying on the mold surface from multiple dimensions. Even for complex parts such as grooves and corners of the mold, it can achieve spraying without dead angles, completely solving the problem of uneven coating caused by the single spraying angle of traditional equipment, and ensuring consistent coating quality.

[0016] The outer frame of this utility model and the liftable enclosed door form a complete enclosed space, and the entire spraying operation is carried out in a closed environment. With the suction pipe on the top of the cover connected to the external suction fan, the paint mist and VOCs generated during spraying can be quickly extracted from the work area, which can significantly reduce air pollution in the workshop and effectively protect the health of operators. At the same time, the enclosed environment can effectively isolate external dust and other impurities, ensure the cleanliness of the coating surface, and further improve the stability of spraying quality.

[0017] The tooling unit of this utility model features a gripper cylinder that drives the gripper to open and close flexibly, allowing for precise adjustment of the clamping force according to molds of different sizes. The flexible contact block on the inner side of the gripper can closely fit the mold surface, avoiding damage to the mold surface caused by rigid clamping and enhancing clamping stability, preventing displacement of the mold during rotation and spraying. In addition, the turntable allows the mold to rotate synchronously with the turntable, enabling all-round spraying without manual flipping, reducing blind spots, and significantly improving the equipment's adaptability to molds of different shapes.

[0018] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the following are the preferred embodiments of this utility model and are described in detail with reference to the accompanying drawings.
