[0034] Reference below Figure 1-Figure 4 The mold buckle inclined ejector structure according to the embodiment of the utility model is described. The accompanying drawings only provide a simple schematic diagram of the product 100, and the actual structure of the product 100 is subject to the specific details.

[0035] like Figure 1-Figure 4 As shown, the mold buckle inclined top demoulding structure includes a product 100 formed in the mold, and the product 100 is provided with a buckle 110 and a frame 120, and a gap is left between the buckle 110 and the frame 120. The mold buckle inclined top demoulding structure is mainly used for demoulding the buckle or slot of the molded product 100 in the injection mold. The product 100 is molded inside the mold and demoulded through the mold buckle inclined top demoulding structure.

[0036] Specifically, the mold buckle inclined top demolding structure includes a mold straight top structure 200 and a mold inclined top structure 300. The mold straight top structure 200 includes an extension part 210 and a straight top part 220. The extension part 210 is used to fill the gap between the buckle 110 and the bone position 120. The bottom of the extension part 210 extends laterally, and a straight top part 220 extends vertically at one end of the extension part 210. In this embodiment, the extension part 210 is a long strip structure, and the straight top part 220 is connected to one end of the extension part 210, so that the extension part 210 and the straight top part 220 are staggered, which is used to increase the distance between the straight top part 220 and the buckle 110.

[0037] The extension part 210 is provided with a clearance groove 211 in the area corresponding to the bone position 120 of the product 100 . The clearance groove 211 is engaged with the bone position 120 , and the end of the extension part 210 fills the gap between the buckle 110 and the bone position 120 .

[0038] In order to solve the problem that the distance between the buckle 110 and the bone position 120 on small-sized shell structures such as earphones is too close, the extension part 210 and the straight top 220 adopt a staggered distribution structure, so that the mold straight top structure 200 maintains the straight top function while increasing the distance between the straight top 220 and the buckle 110, so that the mold inclined top structure 300 can be demoulded in the enlarged space.

[0039] The mold inclined top structure 300 includes a forming part 310, a connecting part 320 and an inclined top part 330. The forming part 310 is used to form the hole 111 of the buckle 110. The forming part 310 is extended toward the straight top part 220 to form a connecting part 320, and the connecting part 320 is extended downward to form an inclined top part 330.

[0040] The end surface of the extension portion 210 close to the connection portion 320 is smoothly arranged, and the mold inclined top structure 300 is slidably demoulded within the interval between the buckle member 110 and the mold straight top structure 200 .

[0041] Specifically, after the straight top 220 of the mold straight top structure 200 is staggered, the distance between the straight top 220 and the buckle 110 increases, so that the mold inclined top structure 300 can be demoulded normally in this space. The demoulding activity stroke is larger, which can optimize the mold structure and reduce the mold manufacturing cost.

[0042] In addition, the mold buckle inclined top demolding structure of this embodiment is simple in structure, which effectively reduces the complexity of mold processing while realizing inclined top demolding. The more movable space of the mold inclined top structure 300 can improve the efficiency of inclined top demolding and the demolding yield rate of the product 100. The extension part 210 of the mold straight top structure 200 is provided with an air avoidance groove 211 for the position of the bone position 120 of the product 100, which can realize ejection and demolding in the narrow area between the bone position 120 and the buckle 110, thereby improving the demolding efficiency.

[0043] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the shape of the end of the extension portion 210 matches the shape of the gap between the buckle 110 and the bone position 120 , and the contour of the avoidance groove 211 matches the contour of the bone position 120 .

[0044] Specifically, the extension part 210 is mainly used to fill the gap between the buckle 110 and the bone 120. The buckle 110 and the bone 120 are too close, so that the normal mold straight top structure 200 cannot be fitted. In order to maintain the structural design of the product 100, it is necessary to retain the gap between the buckle 110 and the bone 120. At this time, the extension part 210 is used to fill the gap between the buckle 110 and the bone 120.

[0045] Specifically, the specific shape of the air-avoiding groove 211 is adjusted accordingly according to the change of the bone position 120 of the structural design of the product 100 .

[0046] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the bottom end surface of the extension part 210 is located between the bone position 120 and the hole position 111. Specifically, after the extension part 210 fills the gap between the buckle 110 and the bone position 120, the extension part 210 extends laterally to increase the available space for demoulding the mold inclined top structure 300, and the bottom end surface of the extension part 210 is flat, which can be used for positioning and fitting the top of the mold inclined top structure 300.

[0047] In a further embodiment, Figure 1-Figure 3 As shown, the distance between the straight top 220 and the buckle 110 is greater than the sum of the lengths of the molding portion 310 and the connecting portion 320. Specifically, the distance between the straight top 220 and the buckle 110 is the extension length of the extension portion 210, and the extension length of the extension portion 210 is set to ensure that the mold inclined top structure 300 can be demoulded and slid within the space formed at the bottom of the extension portion 210.

[0048] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, a demoulding portion 230 is disposed in the straight top portion 220 . When the forming portion 310 slides out of the hole 111 , the demoulding portion 230 lifts the product 100 to separate the bone position 120 from the air avoidance groove 211 .

[0049] Specifically, the demolding part 230 is a pin structure, which is embedded in the straight top 220. After the product 100 is buckled and demolded from the mold inclined ejector structure 300, the product 100 can be ejected through the demolding part 230 in the straight top 220 to demold the product 100. The demolding part 230 is a technical solution well known to those skilled in the art and will not be described in detail in this embodiment. In this embodiment, the demolding part 230 includes a pin 231 and an elastic member 232, which are installed inside the straight top 220, the pin 231 abuts against the surface of the product 100, and the elastic member 232 contacts the bottom of the pin 231. During the demolding process, the elastic member 232 pushes the pin 231 to demold the product 100.

[0050] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the forming part 310 is embedded in and passes through the hole 111 of the buckle 110. Specifically, the hole 111 of the buckle 110 is a through hole, and after the forming part 310 is embedded in the hole 111, the end of the forming part 310 is flush with the end surface of the hole 111 of the buckle 110, that is, the length of the forming part 310 is equal to the depth of the hole 111 of the buckle 110.

[0051] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the side wall of the connecting portion 320 is in contact with the side wall of the buckle 110 .

[0052] Specifically, when the mold inclined top structure 300 is installed in place, the top end surface of the connecting part 320 fits with the bottom end surface of the extension part 210, and the side wall of the connecting part 320 fits with the side wall of the buckle 110, so that the mold inclined top structure 300 will not be displaced during the injection molding process of the product 100 and affect the molding yield of the product 100.

[0053] In some embodiments of the present invention, Figure 1-Figure 4 As shown, the inclined top portion 330 is arranged to be inclined downward from the bottom of the connecting portion 320. Specifically, the inclined top portion 330 is arranged to be inclined, which is a technical solution well known to those skilled in the art and will not be described in detail in this embodiment.

[0054] In a further embodiment, Figure 1-Figure 4 As shown, the distance between the inclined top portion 330 and the straight top portion 220 is greater than the length of the molding portion 310. Specifically, the distance between the inclined top portion 330 and the straight top portion 220 needs to at least reserve a distance for the molding portion 310 to be demoulded from the hole 111.

[0055] In some embodiments of the present invention, Figure 1-Figure 4 As shown, the mold straight top structure 200 and the mold inclined top structure 300 are respectively integrally formed.

[0056] Specifically, the extension part 210 and the straight top part 220 are integrally formed, and the mold straight top structure 200 is integrally formed of metal material, which ensures the structural strength of the position of the air avoidance groove 211 corresponding to the extension part 210 and avoids the air avoidance groove 211 from breaking and causing damage to the mold straight top structure 200.

[0057] The forming portion 310 , the connecting portion 320 and the inclined top portion 330 are integrally formed, and the mold inclined top structure 300 is integrally formed using a metal material to ensure the durability of the mold inclined top structure 300 .
