[0004] However, since the convex post grows obliquely on the shell, the mold for making the above-mentioned oblique convex post cannot perform vertical demoulding action, so the mold design needs to be changed to complete the required structure

Embodiment Construction

[0075] Various embodiments of the present invention will be disclosed below with accompanying drawings, and for the sake of clarity, many practical details will be described together in the following description. It should be understood, however, that these practical details should not be used to limit the invention. That is, in some embodiments of the invention, these practical details are unnecessary. In addition, for the purpose of simplifying the drawings, some conventional structures and elements will be shown in a simplified and schematic manner in the drawings.

[0076] In view of the obliquely extending characteristic of the oblique protruding post formed in the prior art, the oblique protruding post will be interfered by the mold during demolding and cannot be withdrawn. To this end, the present invention provides a mold and method for forming an oblique convex column, so that the hole-forming pin that cooperates with forming the oblique convex column can immediately...

Abstract

A mold for forming tilt boss includes a slider part, a main part and a core pin. The slider part is formed with a tilt groove. The main part is formed with a tilt channel. When the slider part and the first main part are engaged, a tilt-boss forming cavity is formed. The tilt-boss forming cavity is communicated with the tilt channel and coaxial with the tilt channel. The core pin penetrates the tilt channel and one distal portion thereof is slidably engaged with the tilt groove, another distal portion thereof is protruded into the tilt-boss forming cavity. When the slider part is separated from the main part for allowing the core pin to be moved from a high point to a low point of the tilt groove, the core pin is downwardly moved along the tilt channel.

Description

technical field [0001] The invention relates to a mold, in particular to a mold and a method for making oblique convex columns. Background technique [0002] The casing of the electronic device usually has a boss that can be locked with screws. Therefore, the two casings after being closed can be locked to each other by being screwed into the boss. [0003] However, under the thin design of the electronic device, the vertical distance between the two closed shells for screw locking is insufficient, and the longitudinal depth of the inside of the protruding column is also insufficient, which affects the relationship between the closed two shells. locking force between. In this regard, the industry will therefore change the convex column to grow obliquely to strive for its internal longitudinal depth. [0004] However, since the protruding posts are formed obliquely on the shell, the mold for manufacturing the oblique protruding posts cannot perform vertical demolding action...
