[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] Please refer to the following Figures 1 to 6 The box assembly and injection molding equipment according to the embodiments of the present invention are described.

[0032] like Figure 1 、 Figure 2 and Figure 5 As shown, the box assembly of the embodiment of the present invention includes: a box body 1 and a cover plate 2. A accommodating cavity 11 is provided in the box body 1. The accommodating cavity 11 can be used to arrange the pipeline 3 of the injection molding equipment. The box body 1 has an inspection port 12. Part of the inspection port 12 is provided on the top wall of the box body 1, and the other part of the inspection port 12 is provided on the side wall of the box body 1. The cover plate 2 covers the inspection port 12. A connecting portion 25 is provided on the cover plate 2, and the connecting portion 25 is plugged and / or snapped into the box body 1.

[0033] It should be noted that the pipeline 3 of the injection molding equipment can be the pipeline 3 of the motor or the pipeline 3 of the oil pump 4. Of course, the accommodating cavity 11 can also accommodate the oil pump and the motor. The present invention does not specifically limit the components accommodated in the accommodating cavity 11.

[0034] According to the box assembly of the embodiment of the present invention, since part of the inspection port 12 is provided on the top wall of the box 1 and the other part of the inspection port 12 is provided on the side wall of the box 1, when the cover plate 2 is removed from the box 1, the pipeline 3 and other components in the accommodating cavity 11 can be fully exposed to facilitate the operator to inspect and repair them.

[0035] In addition, since the connecting portion 25 on the cover plate 2 can be plugged into and / or snapped into the box body 1, compared to the method of connecting the connecting portion 25 and the box body 1 with multiple screw parts, the cover plate 2 can be quickly separated from the box body 1, thereby facilitating the disassembly and assembly of the box body components, facilitating daily maintenance for operators, and helping to improve utilization rates.

[0036] It is understandable that the side walls of the box body 1 can be the front and rear walls of the box body 1, or the left and right walls of the box body 1. In the example of the present invention, part of the inspection opening 12 is provided on the top wall of the box body 1, and the other part of the inspection opening 12 is provided on the rear wall of the box body 1.

[0037] The operator performs operations on the front side of the box body 1 (ie, the front side of the injection molding equipment), and the rear side of the box body 1 (ie, the rear side of the injection molding equipment) is a non-operation side.

[0038] Alternatively, as Figure 4 and Figure 5 As shown, the cover plate 2 includes a first plate 21 and a second plate 22 connected to each other. The first plate 21 is arranged on the upper side of the second plate 22, and there is an angle between the first plate 21 and the second plate 22. Figure 2 and Figure 3As shown, the inspection port 12 includes a first opening 121 and a second opening 122 . The first opening 121 is provided on the top wall of the box body 1 , and the second opening 122 is provided on the side wall of the box body 1 . The first plate 21 covers the first opening 121 , and the second plate 22 covers the second opening 122 .

[0039] For example, Figure 5 As shown, the included angle between the first plate 21 and the second plate 22 may be 90°, or slightly greater than 90° or slightly less than 90°.

[0040] It can be understood that the first plate 21 and the second plate 22 are generally L-shaped sheet metal structures, the first plate 21 is used to close the first opening 121, and the second plate 22 is used to close the second opening 122, thereby making it convenient for operators to disassemble and assemble the cover plate 2.

[0041] In some embodiments, as Figure 4 and Figure 6 As shown, the cover plate 2 further includes a transparent observation window 24 , which is provided on at least one of the first plate 21 and the second plate 22 , thereby facilitating routine inspections of the interior of the accommodating cavity 11 by operators without opening the cover plate 2 .

[0042] For example, the transparent observation window 24 is provided on the first plate 21. For another example, the light-transmitting observation window is provided on the second plate 22. Alternatively, both the first plate 21 and the second plate 22 are provided with light-transmitting observation windows.

[0043] Alternatively, as Figure 4 and Figure 5 As shown, the cover plate 2 further includes a transition plate 23, through which the first plate 21 is connected to the second plate 22. The outer wall of the transition plate 23 is an inclined surface or a curved surface. It is understood that the connection between the first plate 21 and the second plate 22 has a transition bevel or a transition fillet to reduce the probability of the top corner of the cover plate 2 striking the operator.

[0044] Furthermore, if Figure 1 and Figure 4 As shown, the box assembly further includes a handle 26, which is mounted on the outer wall of the cover plate 2 to facilitate the operator in taking and placing the cover plate 2. For example, the handle 26 is mounted on the outer wall of the transition plate 23 to avoid the handle 26 protruding upward or to the side of the box body 1, thereby reducing the overall space occupied by the cover plate 2 and facilitating its removal and placement.

[0045] In some embodiments, as Figure 2 、 Figure 3 and Figure 5As shown, the connecting portion 25 includes a flange 251, which is provided on at least one of the first plate 21 and the second plate 22. The housing 1 is provided with an insertion hole 13, into which the flange 251 is inserted. It is understood that the flange 251 can be inserted into the insertion hole 13 of the housing 1 to secure the cover plate 2. This allows the operator to quickly separate the cover plate 2 from the housing 1, making it easier to disassemble and assemble the housing assembly and facilitating routine maintenance.

[0046] For example, the convex edge 251 is provided on the first plate 21. For another example, the convex edge 251 is provided on the second plate 22. Alternatively, the convex edge 251 is provided on both the first plate 21 and the second plate 22.

[0047] Specifically, if Figure 3 and Figure 5 As shown, the connecting portion 25 includes a first flange 2511, which is provided at the end of the first plate 21 facing away from the second plate 22 and extends horizontally. The box body 1 is provided with a first insertion hole 131, and the first flange 2511 is plugged into and engaged with the first insertion hole 131 along the width direction of the box body 1. This allows the operator to mate and detach the first flange 2511 with the first insertion hole 131 on the box body 1 along the width direction of the box body 1, making it easier for the operator to assemble and disassemble the cover plate 2.

[0048] Optionally, there are at least two first convex edges 2511, and the two first convex edges 2511 are spaced apart on the first plate 21 along the length direction of the box body 1. This can improve the stability and reliability of the connection between the first plate 21 and the box body 1.

[0049] In the example of the present invention, the first flange 2511 elastically abuts against the inner wall of the first plug-in hole 131. It can be understood that after the first flange 2511 is installed in the first plug-in hole 131, the first flange 2511 can undergo a certain elastic deformation, thereby reducing the probability of relative shaking between the first flange 2511 and the first plug-in hole 131 after installation, and improving the stability of the connection between the first flange 2511 and the plug-in hole 131.

[0050] Alternatively, as Figure 3 and Figure 5 As shown, the connecting portion 25 includes a second flange 2512, which is provided at an end of the second plate 22 facing away from the first plate 21 and extends in the vertical direction of the housing 1. The housing 1 is provided with a second insertion hole 132, and the second flange 2512 is plugged into and engaged with the second insertion hole 132 in the vertical direction of the housing 1. It is understood that the second flange 2512 is provided at the lower end of the second plate 22 and extends in the vertical direction, thereby allowing an operator to separate the second flange 2512 of the second plate 22 from the second insertion hole 132 of the housing 1 in the vertical direction, thereby facilitating the operator's disassembly and assembly of the cover plate 2.

[0051] For example, a connection hole 27 for installing a screw is provided on the second flange 2512, and the screw is passed through the connection hole 27 between the box body 1 and the second flange 2512 to further fix the cover 2, thereby improving the firmness of the connection of the cover 2.

[0052] In some embodiments, as Figure 2 As shown, there are multiple access openings 12, arranged sequentially along the length of the housing 1. There are multiple cover plates 2, each correspondingly covering the access openings 12, with adjacent cover plates 2 being independent of each other. Compared to a solution where a single cover plate 2 covers multiple access openings 12, this makes it easier for operators to remove and install the cover plates 2 corresponding to access openings 12 at different locations, thereby improving maintenance efficiency.

[0053] like Figure 1 As shown, the injection molding equipment of another embodiment of the present invention includes the box assembly of the present invention.

[0054] Optionally, the box assembly can carry a feed module (not shown) of the injection molding device. For example, the oil pump 4, the motor and the pipeline 3 connected to the injection molding device can be arranged in the box assembly.

[0055] According to the injection molding equipment of the embodiment of the present invention, since part of the inspection opening 12 is provided on the top wall of the box body 1 and the other part of the inspection opening 12 is provided on the side wall of the box body 1, when the cover plate 2 is removed from the box body 1, the pipeline 3 and other components in the accommodating cavity 11 can be fully exposed, so that the operator can inspect and repair them. In addition, since the connecting portion 25 on the cover plate 2 can be plugged and / or snapped into the box body 1, compared with the method of connecting the connecting portion 25 to the box body 1 using multiple screw parts, the cover plate 2 can be quickly separated from the box body 1, thereby making it easy to disassemble and assemble the box body assembly, which is convenient for the operator's daily maintenance.
