[0035] Reference below Figure 1-Figure 5 The mold inclined top demoulding 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.

[0036] like Figure 1-Figure 5 As shown, the mold slant top demoulding structure includes a product 100 formed in the mold, and the product 100 is provided with a buckle 110 and a structural member 120, and a gap is left between the buckle 110 and the structural member 120. The mold slant top demoulding structure is mainly used for demoulding the buckle or groove of the molded product in the injection mold. The product 100 is molded inside the mold and demoulded through the mold slant top demoulding structure.

[0037] Specifically, the mold inclined top demoulding structure includes a mold straight top structure 200 and a mold inclined top structure 300. The mold straight top structure 200 includes a filling portion 210, an extension portion 220 and a straight top portion 230. The filling portion 210 is used to fill the gap between the buckle 110 and the structural member 120. The bottom of the filling portion 210 is laterally provided with an extension portion 220, and the end of the extension portion 220 is downwardly provided with a straight top portion 230, and the extension portion 220 is used to increase the distance between the straight top portion 230 and the buckle 110.

[0038] In order to solve the problem that the distance between the buckle 110 and the structural part 120 on small-sized shell structures such as earphones is too close, the filling part 210 and the straight top 230 adopt a staggered distribution structure, and the filling part 210 and the straight top 230 are connected by an extension part 220, so that the mold straight top structure 200 maintains the straight top function while increasing the distance between the straight top 230 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 230 to form a connecting part 320, and the connecting part 320 is extended downward to form an inclined top part 330.

[0040] Among them, the top of the connecting part 320 abuts against the bottom of the extension part 220, and the mold inclined top structure 300 slides between the hole 111 of the buckle 110 and the mold straight top structure 200 for demoulding. Specifically, after the extension part 220 of the mold straight top structure 200 misaligns the straight top 230, the distance between the straight top 230 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. In addition, the mold inclined top demoulding structure of this embodiment has a simple structure, which effectively reduces the complexity of mold processing while realizing inclined top demoulding. The more activity space of the mold inclined top structure 300 can improve the efficiency of inclined top demoulding and the demoulding yield rate of the product 100.

[0041] In some embodiments of the present invention, Figure 1-Figure 4 As shown, the shape of the filling portion 210 matches the shape of the gap between the buckle 110 and the structural member 120. Specifically, the filling portion 210 is mainly used to fill the gap between the buckle 110 and the structural member 120. The buckle 110 and the structural member 120 are too close to each other, which makes it impossible for the normal mold straight top structure 200 to fit together. In order to maintain the structural design of the product 100, it is necessary to retain the gap between the buckle 110 and the structural member 120. At this time, the filling portion 210 is used to fill the gap between the buckle 110 and the structural member 120.

[0042] Specifically, the specific shape of the filling portion 210 is adjusted accordingly according to the change of the structural design of the product 100 , and the main function of the filling portion 210 is to fill the gap between the buckle 110 and the structural member 120 .

[0043] In some embodiments of the present invention, Figure 1-Figure 4 As shown, the bottom end surface of the extension part 220 is higher than the top end surface of the hole 111 of the buckle 110. Specifically, after the filling part 210 fills the gap between the buckle 110 and the structural member 120, the extension part 220 extends laterally to increase the available space for demoulding the mold inclined roof structure 300. The bottom end surface of the extension part 220 is flat, which can be used for positioning and fitting the top of the mold inclined roof structure 300.

[0044] In a further embodiment, Figure 1-Figure 4As shown, the distance between the straight top 230 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 230 and the buckle 110 is the extension length of the extension portion 220, and the length of the extension portion 220 is set to ensure that the mold inclined top structure 300 can be demoulded and slid within the space formed by the extension portion 220.

[0045] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the filling portion 210, the extension portion 220 and the straight top portion 230 are integrally formed. Specifically, the mold straight top structure 200 is integrally formed of metal material, which ensures the structural strength of the extension portion 220 and prevents the extension portion 220 from breaking and causing damage to the mold straight top structure 200.

[0046] In some embodiments of the present invention, Figure 1-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.

[0047] In some embodiments of the present invention, Figure 1-Figure 4 As shown, the side wall of the connecting portion 320 is fitted with the side wall of the buckle 110. Specifically, when the mold inclined top structure 300 is installed in place, the top end surface of the connecting portion 320 is fitted with the bottom end surface of the extension portion 220, and the side wall of the connecting portion 320 is fitted 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 to affect the molding yield of the product 100.

[0048] 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.

[0049] In a further embodiment, Figure 1-Figure 4 As shown, the distance between the inclined top portion 330 and the straight top portion 230 is greater than the length of the molding portion 310. Specifically, the distance between the inclined top portion 330 and the straight top portion 230 needs to at least reserve a distance for the molding portion 310 to be demoulded from the hole 111.

[0050] In some embodiments of the present invention, Figure 4 and Figure 5As shown, the forming portion 310, the connecting portion 320 and the inclined top portion 330 are integrally formed. Specifically, the mold inclined top structure 300 is integrally formed of metal material to ensure the durability of the mold inclined top structure 300.

[0051] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.
