Description

Storage box mold structure

The invention relates to a storage box mould structure, in particular to a storage box mould structure which can make the shaping of the storage box more smooth.

In general, some locomotives are currently equipped with compartments to provide the ability to place items such as helmets and raincoats.

Referring to FIG. 1, a conventional locomotive compartment 1 is disposed in a locomotive M, and mainly includes a casing 10. The case 10 has a bottom portion 11 and an opening portion 12. The bottom portion 11 is opposite to the opening portion 12. Here, a seat cushion M1 of the locomotive M is detachably covered on the opening portion 12.

As described above, in such a conventional locomotive compartment 1, the projected area of one of the bottom portions 11 is generally equal to or smaller than the projected area of one of the openings 12. Therefore, when the locomotive compartment 1 is applied to the locomotive M, there is a large idle space S between the front edge of the casing 10 and the intermediate casing M2 of the locomotive M, and the idle space S affects the locomotive. The effective use space in the compartment 1.

Therefore, in order to solve the above problems, another conventional locomotive compartment 100 has appeared, as shown in Fig. 2. Here, the locomotive compartment 100 also mainly includes a casing 110. The casing 110 has a bottom portion 111 and an opening portion 112. The bottom portion 111 is opposite to the opening portion 112, and the bottom portion 111 is extended in a specific direction such that one of the bottom portions 111 has a projected area larger than a projected area of the opening portion 112. In other words, the case 110 has a shape that gradually expands from the opening portion 112 toward the bottom portion 111.

As described above, when the locomotive compartment 100 is applied to a locomotive, the leading edge of the casing 110 is approximately parallel to the intermediate casing of one of the locomotives. Therefore, an idle space between the front edge of the casing 110 and the intermediate casing of the locomotive is greatly reduced, and the effective use space in the locomotive compartment 100 is greatly increased.

However, since the locomotive storage compartment 100 generally has to be manufactured by means of a mold in an integrally formed manner, the mold for producing the locomotive storage compartment 100 may be angled by the shape of the casing 110 gradually expanding from the opening portion 112 toward the bottom portion 111. The problem (as shown by the angled area A in Fig. 2) causes the locomotive compartment 100 that is plastically injection molded to be ejected from the mold, which may cause problems in mass production.

In view of the above, an object of the present invention is to provide a storage box mold structure which can solve the problem that the storage box cannot be smoothly removed from the mold due to the presence of the bezel.
