Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic and metal forming machines, in particular to a safety door structure suitable for plastic and metal forming machines. Background Art
[0002] During the operation of die-casting and injection molding machines, the splashing of hot metal or plastic solutions during the injection stage is a serious safety issue. Once these solutions come into contact with the operator's skin, they are likely to cause serious injuries such as burns. Therefore, equipping safety doors has become a necessary measure to ensure operational safety. At the same time, the market demand for beautiful and powerful safety doors is also increasing.
[0003] Currently, most security doors on the market use a simple flat door panel structure, which is directly fixed to the profile frame by screws. A major disadvantage of this design is that all screw locking points are exposed on the outside of the door, which not only affects the overall appearance of the equipment, but also has a weaker ability to resist impact due to the limitations of the door panel's mechanical structure.
[0004] In view of these problems, the existing safety doors have deficiencies in aesthetics and mechanical structural strength, and need to be optimized and improved through design innovation to achieve higher safety standards and better visual effects. Utility Model Content
[0005] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a safety door structure suitable for plastic and metal forming machines, which has better aesthetics and mechanical strength when in use.
[0006] In order to solve the above technical problems, the technical solution provided by the utility model is:
[0007] A safety door structure suitable for plastic and metal forming machines comprises a safety door plate, a profile frame and screws. The safety door plate is fixed to the profile frame by screws, and the screws are arranged on the inner side of the safety door plate in a hidden manner.
[0008] As an improvement, the upper and lower convex edges of the safety door panel are both folded inwardly 180°, and after the left and right sides are folded inwardly 180°, they are further bent backward 90° to form hems, and the hems are fixed to the profile frame by screws.
[0009] As an improvement, waist-shaped holes inclined downward are reserved on the frill corresponding to the screws.
[0010] The advantages of the utility model compared with the prior art are:
[0011] 1. This new model improves safety: by setting the screw locking point on the inner side of the safety door panel, the risk of operators coming into contact with sharp screws in daily use is reduced, thus improving the safety of the working environment;
[0012] 2. Enhanced aesthetics of the new model: The hidden screw fixing design makes the new model more beautiful and more in line with the aesthetics of modern industrial design;
[0013] 3. This new model simplifies installation: the downward-sloping waist-shaped hole design simplifies the installation process, making installation faster and maintenance more convenient;
[0014] 4. The new structure has enhanced strength: the folding treatment on the edge of the safety door panel improves its impact resistance and ensures long-term stable use. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In the description of the present utility model, it should be understood that the terms "center", "lateral", "up", "down", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model 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 a limitation on the present utility model. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more. In addition, the term "including" and any variation thereof are intended to cover non-exclusive inclusions.
[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0022] A safety door structure suitable for plastic and metal forming machines, comprising:
[0023] Safety door panel 1, profile frame 2 and screws 3; the upper and lower convex edges 4 of the safety door panel 1 are both punched and folded 180° inward, and the left and right sides are punched and folded 180° inward, and then continue to punch and bend 90° backward to form a frill 5, and the frill 5 is fixed to the profile frame 2 by screws 3, and a waist-shaped hole 6 inclined 45° downward is reserved on the frill 5 corresponding to the screws 3.
[0024] It is worth mentioning that the profile frame 2 is formed by assembling or welding profiles. This structure not only enhances the neatness and beauty of the safety door structure, but also improves the structural strength of the edge of the safety door panel 1.
[0025] In the specific implementation of this embodiment:
[0026] The waist-shaped holes 6 on the frill 5 are buckled onto the screws 3, and the safety door panel 1 is fixed to the profile frame 2 via the screws 3. The screws 3 are arranged on the inner side of the safety door panel 1 and are concealed.
[0027] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
