Cylindrical storage box manufacturing mold

Abstract

A cylindrical storage box manufacturing mold comprises a mold base, an outer mold and a core mold; the mold base comprises nozzle plates, an outer mold pressing plate, an outer mold sliding base and abase which are sequentially stacked from top to bottom; the outer mold comprises a top plate, a bottom plate, a front outer mold and a rear outer mold which define two vertical columnar through holecavities; the outer mold sliding base is provided with a sliding groove for mounting the front outer mold and the rear outer mold; a mold pressing groove is formed in the outer mold pressing plate forachieving slope fit so that the front outer mold and the rear outer mold can be transversely extruded and limited; a sliding member of which a plurality of sliding blocks are circumferentially spliced into a polygonal vertical inner hole, and a fixed member of the core mold are in slope sleeving fit; the outer peripheral surface of the sliding member is a cylindrical surface on which cylindricalconvex rings and cylindrical grooves are arranged at intervals; the sliding blocks are formed by obliquely cutting a sleeve downwards along the hole wall of the vertical inner hole with the non-adjacent edges of the radial cross section of the vertical inner hole as chord lines; the fixed member is fixedly mounted, and the fixed member and the sliding member penetrate through core mold through holes in the bottom plate and extend into a cavity to form a mold cavity; and the bottom plate presses against sliding block outwards-convex shoulders for limiting. The problems that demolding is difficult and the core mold is liable to shake are solved.

Description

technical field [0001] The invention belongs to a manufacturing mold, in particular to a cylindrical storage box manufacturing mold. Background technique [0002] The patent No. ZL201220084731.5 discloses a cylindrical storage box used as a pen holder. The box structure includes a main box and a side box with an open top. Grid, the grid is composed of ring-shaped grid strips arranged at intervals along the axial direction, and the solid part and the grid part which are divided and connected in the axial direction are respectively formed on the main box body and the auxiliary box body. The thickness of the solid part is Larger than the grille part, the grids of the main box body and the auxiliary box body are staggered and inserted, and the inner cavity walls of the solid part of the main box body and the auxiliary box body are respectively provided with inner grooves corresponding to the grid bars. The main box body and the auxiliary box body After the boxes are mated and a...
