Double-stage injection type brush handle injection molding equipment

Abstract

The invention provides double-stage injection type brush handle injection molding equipment. The double-stage injection type brush handle injection molding equipment structurally comprises a machine base, a plastic melting bin, a feeding bin, a pressing-fit block and a molding device, the bottom end of the plastic melting bin is connected to the right side of the upper end of the machine base through bolts, the bottom end of the feeding bin is fixedly connected to the interior of the upper end of the plastic melting bin in an embedded mode, the interior of the left side of the pressing block is connected to the right side of the molding device in a clamped mode, and the bottom end of molding device is connected to the left side surface of upper end of base in an embedded mode. According to the double-stage injection type brush handle injection molding equipment, through extrusion of the upper end of a fixing device during secondary injection molding, an upper end piece of an elastic column forms downward extrusion force on the tail end of the right side of a connecting rod, then the connecting rod is driven by a torsion spring to rotate a clamping mechanism to clamp burrs of a main handle body, and under the buffering of a buffering mechanism in the interior of the clamping mechanism, the contact between the clamping block and the burrs is tighter, so that the burrs are further prevented from swinging in the secondary injection molding process.

Description

technical field [0001] The invention relates to the field of plastic injection, in particular to a double-stage plastic injection type brush handle injection molding equipment. Background technique [0002] The two-stage plastic injection type brush handle injection molding equipment is a special injection molding equipment that sets the two-color injection molding stages of the two-color toothbrush handle on the same machine. When making the toothbrush handle, it needs to make the main handle body first, and then the main handle that is not fully finalized The plastic injection molding of the auxiliary handle is carried out on the surface of the handle body, so that the splicing of the two-color toothbrush handle can be intersected when hot-melted to avoid the generation of gaps. When the toothbrush is produced by injection molding, in the process of secondary injection molding on the surface of the main handle body, because the main handle body needs to be subjected to sec...

[0002] The two-stage plastic injection type brush handle injection molding equipment is a special injection molding equipment that sets the two-color injection molding stages of the two-color toothbrush handle on the same machine. When making the toothbrush handle, it needs to make the main handle body first, and then the main handle that is not fully finalized The plastic injection molding of the auxiliary handle is carried out on the surface of the handle body, so that the splicing of the two-color toothbrush handle can be intersected when hot-melted to avoid the generation of gaps. When the toothbrush is produced by injection molding, in the process of secondary injection molding on the surface of the main handle body, because the main handle body needs to be subjected to secondary injection molding in a semi-molded state, it is impossible to remove the burr formed on the side by one injection molding. The burr of the handle body will swing during the secondary injection molding, which will cause the burr to be melted and absorbed by the hot melt plastic of the secondary injection molding, resulting in mixed color of the plastic of the secondary injection molding and lower product quality
