Abstract
The utility model provides a structure for finely positioning a closed front mould core and back mould core. According to the structure, the machining cost is low and the machining precision is high, and a front mould core and a back mould core are interlocked, so that the technical requirement of accurate positioning of a mould can be ensured, and the quality of the mould can be improved. The structure comprises the front mould core and the back mould core, and is characterized in that linear grooves are respectively formed in the both sides of the opposite edges of a parting face of the front mould core in a penetrating manner, and an outward-convex linear convex strips are arranged at the other opposite edges of the parting face of the front mould core; the both ends of the linear convex strips do not extend into spaces of the linear grooves; penetrated linear grooves are respectively formed in the both sides of the opposite edges of a parting face of the back mould core corresponding to the linear convex strips of the front mould core, and outward-convex straight strips are arranged at the other opposite edges of the parting face of the back mould core; and the both ends of the outward-convex straight strips do not penetrate into the spaces of the linear grooves.
Description
Technical field
The utility model relates to the technical field of structures of mould, is specially the structure of a kind of front cavity, rear cavity matched moulds fine positioning.
Background technology
In mould structure, the precise positioning structure of front and back model cavity is extremely important.Usually adopt Design Orientation structure, i.e. front mould projection on four jiaos of the die joints of front cavity, rear cavity; The structure that mutually accurately cooperates that rear mold is recessed.When mould is in the matched moulds state, play the accurate interlocking of front cavity, rear cavity, prevent that front mould, rear mold from misplacing and affecting the attractive in appearance of product die joint place.But in the Mould Machining process of reality, the dimensional accuracy that needs adopt the processing conditions ability Reliable guarantee mould fine positioning of high-precision machining center or high-precision surface grinding machine partly to require, processing cost is higher.Although designed the fine positioning structure of front cavity, rear cavity interlocking on the ordinary circumstance bed die, defective because of machining accuracy, do not have pinpoint effect and perform practically no function.
Summary of the invention
For the problems referred to above, the utility model provides the structure of a kind of front cavity, rear cavity matched moulds fine positioning, and its processing cost is low, and machining accuracy is high, thereby so that the interlocking of front cavity, rear cavity, guaranteed that mould realizes pinpoint specification requirement, improved the quality of mould.
The structure of a kind of front cavity, rear cavity matched moulds fine positioning, its technical scheme is such: it comprises front cavity, rear cavity, it is characterized in that: wherein opposite side both sides of the die joint of described front cavity have the vertical bar type groove that runs through, the straight line raised line that another opposite side is provided with evagination, and the two ends of described straight line raised line are not stretched in the space of described vertical bar type groove; One opposite side both sides of the straight line raised line of the corresponding described front cavity of the die joint of described rear cavity are respectively arranged with the linear pattern groove that runs through, another opposite side of the die joint of described rear cavity is provided with the evagination vertical bar, the two ends of described evagination vertical bar are not goed deep in the space of described linear pattern groove, the straight line raised line of described front cavity die joint is positioned the linear pattern groove of described rear cavity die joint, and the evagination vertical bar of described rear cavity die joint is positioned the vertical bar type groove of described front cavity die joint.
After adopting said structure of the present utility model, because the straight line raised line of front cavity die joint is positioned the linear pattern groove of described rear cavity die joint, the evagination vertical bar of described rear cavity die joint is positioned the vertical bar type groove of described front cavity die joint, and the two ends of straight line raised line are not stretched in the space of described vertical bar type groove, the two ends of evagination vertical bar are not goed deep in the space of described linear pattern groove, it is so that directly adopt grinding machine to carry out accurately machinedly can processing the qualified structure of precision, its processing cost is low, and machining accuracy is high, thereby so that front cavity, the rear cavity interlocking, guaranteed that mould realizes pinpoint specification requirement, improved the quality of mould.
