Description

Multi-surface engraving insert switching structure

Technical Field

The utility model relates to the technical field of mold, more specifically relate to a multiaspect mold insert switching structure of carving characters.

Background

For products molded by the same mold, different trademarks and identification requirements exist under different sales conditions, and movable inserts are usually manufactured on the mold so as to be changed at any time according to different market requirements. According to the traditional method, corresponding inserts are required to be manufactured for the die to be switched, so that the manufacturing cost of the die is increased.

Most of the prior art only improves the structure of the insert installation, so that the insert can be exchanged more quickly and conveniently, but the structure of the insert is not improved, so that the insert can meet the requirements of different trademarks and marks. For example, chinese patent CN209320282U discloses a very convenient installation structure of a lettering insert in a blow molding shaping mold, wherein the lettering insert is made of ferromagnetic material, a magnet is disposed on the bottom wall of the insert for adsorbing the lettering insert, the lettering insert is fixed by a magnet adsorption method, and only the magnet with stronger magnetic force is needed to suck the lettering insert out during disassembly. However, only the insert material is changed, the essence of the insert material is the improvement of the insert mounting structure, so that the insert is more convenient to replace, and the problem of production cost rise caused by the fact that corresponding inserts are required to be matched with different identification requirements is not solved; in addition, when the number of inserts is large, the inserts outside the molds are easy to lose along with the frequent conveying of the molds, and the management is very difficult.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an overcome among the above-mentioned prior art different identifications need different mold inserts to correspond and cause the cost of manufacture to rise, a plurality of mold inserts are difficult to the not enough of transportation management, provide one kind can reduce mould cost of manufacture, be convenient for management, a multiaspect carving characters mold insert switching structure that mold insert corresponds multiple sign requirement.

In the technical scheme, the multi-surface lettering insert switching structure comprises a mold and an insert mechanism, wherein the mold comprises a panel, a template fixedly connected with the panel and a mold core fixedly arranged in the template; the mold core is provided with a cavity surface, the insert mechanism comprises a multi-surface insert and an ejector rod, the multi-surface insert is detachably arranged in the mold core, the ejector rod is in sliding fit with the mold core and the template, one end of the ejector rod is movably connected with the multi-surface insert, and the other end of the ejector rod is a free end; the multi-surface insert is provided with at least two lettering surfaces matched with the cavity surface of the mold core.

In the technical scheme, the detachable multi-surface insert is arranged in the mold core, the multi-surface insert is provided with at least two lettering surfaces engraved with different contents, and the lettering surfaces are matched with the cavity surface, so that corresponding identification contents are formed on the outer surface of a product during injection molding; when the identification content needs to be replaced, external force is applied to one end of the ejector rod, so that the multi-surface insert in the mold core is separated out, the mounting direction of the multi-surface insert is changed, another lettering surface is matched with the surface of the mold cavity to form a complete molding surface, next injection molding is carried out, and another corresponding identification content is formed on the outer wall of a product. Therefore, the condition that corresponding inserts are manufactured in different mark contents is avoided, the production cost can be greatly reduced, the transportation of the inserts is reduced, the loss probability is reduced, and the production management is facilitated.
