Referring to fig. 1 to fig. 5, in the present embodiment, the first buckle 120 and the second buckle 130 are disposed near the periphery of the end cap 100, and a connection line between the first buckle 120 and the second buckle 130 vertically extends along the vertical direction, that is, in the front-back direction, the first buckle 120 and the second buckle 130 are substantially located at the same position. Meanwhile, the first buckle 120 and the second buckle 130 are arranged at an upper-lower interval, specifically, the first buckle 120 is located at the upper half part of the end cover 100, and the second buckle 130 is located at the lower half part of the end cover 100, so that the edges of the end cover 100 corresponding to the first buckle 120 and the second buckle 130 can be tightly matched with the middle frame 200.

Further, the first catch 120 and the second catch 130 are both located at the front end of the end cap 100, i.e., the first catch 120 and the second catch 130 are both located at the front half of the end cap 100. When the indoor unit 10 of the air conditioner is installed, the front end of the end cover 100 faces the indoor, and the first buckle 120 and the second buckle 130 arranged at the front end of the end cover 100 can effectively ensure the close fit between the front end of the end cover 100 and the front end of the middle frame 200, so that the appearance is more attractive. The first clamping protrusion 121 is disposed toward the outer side of the end cap 100, and the second clamping protrusion 131 is disposed toward the inner side of the end cap 100, in other words, the first clamping protrusion 121 is disposed toward the front of the end cap 100, and the second clamping protrusion 131 is disposed toward the rear of the end cap 100. Specifically, the first catch 120 and the second catch 130 are each disposed proximate a front vertical edge of the end cap 100.

The cross section of the through hole 122 is substantially in a round square shape, i.e. a square structure with round corners. Meanwhile, the portion of the circumferential surface of the through hole 122, which is located at the upper end of the through hole 122, is a plane, the first engaging protrusion 121 is located at the upper side of the through hole 122, and the engaging surface of the first engaging protrusion 121 is coplanar with the plane. Therefore, the clamping surface of the first clamping protrusion 121 can be synchronously molded with the through hole 122, and the molded first clamping protrusion 121 does not limit the movement of the mold along the direction from the outer side of the end cover 100 to the inner side of the end cover 100.

Specifically, the first buckle 120 is formed by the cooperation of two molds, namely a first mold 311 and a second mold 312, wherein the first mold 311 is used for forming the part of the first buckle 120 facing the front side of the end cap 100, and the second mold 312 is used for forming the part of the second buckle 130 facing the back side of the end cap 100. Meanwhile, the portion of the second mold 312 extends to the first mold 311 to mold the clamping surface of the first clamping protrusion 121 and form the through hole 122 synchronously, so that when demolding is performed, the first mold 311 directly demolds the plate body 110 far away from the end cover 100, the second mold 312 firstly slides to the rear side of the end cover 100 until the second mold separates from the through hole 122 and then moves in the direction far away from the plate body 110 of the end cover 100 to realize demolding (as shown by an arrow in fig. 5). In addition, since the first mold 311 only needs to move in the direction away from the plate body 110 of the end cap 100 when demolding, the demolding of the first mold 311 is not affected by the protrusion matching structure 111 arranged on the periphery of the end cap 100, which is convenient for demolding.

Meanwhile, since the second clamping protrusion 131 is disposed toward the inner side of the end cap 100, when the second buckle 130 is formed, a demolding process of a mold (hereinafter, referred to as a third mold) for forming the clamping surface of the second clamping protrusion 131 includes firstly sliding toward the rear side of the end cap 100 until the second clamping protrusion 131 is separated from the clamping surface and then moving in a direction away from the plate body 110 of the end cap 100. That is, the demolding direction of the third mold is consistent with the demolding direction of the second mold 312, so that the third mold and the second mold 312 can be simultaneously demolded, and the demolding process is simpler and more convenient.

It should be noted that, in the present embodiment, the clamping surface of the first clamping protrusion 121 is coplanar with the circumferential surface of the through hole 122, so as to ensure that the second mold 312 can be smoothly demolded after the first clamping protrusion 121 is formed, and it can be understood that, in some other embodiments, the clamping surface may be set to protrude out of the circumferential surface of the through hole 122, so as to ensure that the second mold 312 can be smoothly demolded.

Further, the size of one end of the through hole 122 close to the first clamping protrusion 121 along the length direction of the first clamping protrusion 121 is an opening size, and the opening size is greater than or equal to the length size of the first clamping protrusion 121. That is, in this embodiment, the opening size of the through hole 122 refers to the size of the upper plane of the through hole 122 in the length direction of the first clamping protrusion 121, and accordingly, the size of the clamping surface of the second mold 312 for molding the first clamping protrusion 121 is smaller than or equal to the size of the upper plane of the through hole 122 for molding the second mold 312, so as to meet the molding requirement.
