Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, and not all embodiments.
Example (b):
referring to fig. 1 to 6, the present embodiment is a die structure for improving gas marks and preventing pulling damage of a keyboard key, including a plurality of glue injection runners 11 disposed in a lower die plate 1, and branch runners 12 connected to ends of the glue injection runners 11 and connected to a lower die core 2, where ends of the branch runners 12 extend to an inner portion of a side edge of the lower die core 2 to form a glue inlet 13, an upper die core 3 is recessed in a bottom surface of the upper die plate, the upper die core 3 is fastened to a periphery of the lower die core 2 at intervals to form a cavity of an injection molding 4, and the glue inlet 13 is located inside the upper die core 3 and the glue injection faces a side wall of the upper die core 3.
Flat thimbles (not shown in the figure) penetrating through the lower template 1 are arranged on two symmetrical sides of the lower die core 2, and the surfaces of the flat thimbles are telescopic and sunken in the lower die core 2. The flat thimble has the effect of positioning and ejecting the injection molding 4 in the cavity, and the deformation problem caused by the ejection of the middle part of the injection molding 4 in a centralized manner is avoided.
The lower die core 2 is of a square structure protruding out of the surface of the lower template 1, through holes 21 avoiding flat thimbles are formed in the two sides of the lower die core 2, and the outer sides of the flat thimbles are flush with the side wall of the lower die core 2.
