Technical Field
[0001] This utility model relates to the field of side door structure technology, specifically to a side door structure for a vertical injection molding machine hardware frame that facilitates maintenance. Background Technology
[0002] A vertical injection molding machine is a type of injection molding equipment mainly used to mold thermoplastic or thermosetting materials into various shapes of plastic products using plastic molds. Its injection unit and clamping unit are located on the same vertical center line, and the mold opens and closes in the vertical direction. It occupies only about half the area of a horizontal machine, thus its production capacity is approximately twice that of a horizontal machine with the same floor space. During the use of a vertical injection molding machine, equipment inspection and maintenance are crucial.
[0003] Traditional side door structures for injection molding machine frames have many inconveniences. Their connection methods are simple and fixed, the opening angle of the side door is limited, which is not conducive to the entry and exit of large maintenance tools and the comprehensive inspection of internal components. The sealing performance is poor, which makes it easy for dust and debris to enter the machine frame, affecting the normal operation and service life of electrical, hydraulic and other components. Moreover, when deep repair or replacement of the side door or its internal components is required, the traditional side door is difficult to disassemble, which consumes a lot of time and manpower, reduces the maintenance efficiency of the equipment, increases the downtime of the equipment, and thus affects the production progress and enterprise benefits. Therefore, a side door structure for the hardware frame of a vertical injection molding machine that is easy to maintain is proposed. Utility Model Content

[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] This utility model provides a technical solution for a side door structure of a vertical injection molding machine frame that facilitates maintenance. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The system includes a door frame 1, an inner frame 7 inside the door frame 1, and the inner frame 7 is connected to the door frame 1. The inner frame 7 has threaded holes 9 and grooves 8 inside, and the threaded holes 9 and grooves 8 are arranged sequentially. A panel 5 is provided at the front end of the inner frame 7. A bolt 6 is provided inside the panel 5 at the position corresponding to the threaded hole 9, and the bolt 6 is adapted to the threaded hole 9. A buckle 10 is provided inside the panel 5 at the position corresponding to the groove 8, and the buckle 10 is adapted to the groove 8. A hinge 2 is also provided on the upper and lower sides of one end of the door frame 1, and the hinge 2 is connected to the door frame 1. A trapezoidal sealing rubber strip 12 is also installed on the back side of the door frame 1.
[0025] Please see Figure 5 and Figure 6 The door frame 1 has a back groove 11 at its inner rear end, and the back groove 11 is integrally formed with the door frame 1. The back groove 11 is used for the installation of the trapezoidal sealing rubber strip 12.
[0026] Please see Figure 5 and Figure 6 The trapezoidal sealing rubber strip 12 is embedded and connected to the back groove 11.
[0027] Please see Figure 2 and Figure 5 The inner frame 7 has internal supports 13 at each of its four corners, and the internal supports 13 are connected to the inner frame 7. The internal supports 13 are used to improve the strength of the corners of the inner frame 7.
[0028] Please see Figure 1 , Figure 2 and Figure 5A door lock 4 is provided at the middle position of the left end of the door frame 1, and the door lock 4 is connected to the door frame 1. The door lock 4 is used to lock and fix the door frame 1.
