Description
Technical Field
The utility model belongs to the technical field of the locating pin, especially, relate to a mould locating pin that auto-lock performance is strong.
Background
The locating pins, with the workpiece holes as the locating reference, participate in the part that limits the freedom of the object, control the linear motion of the object in X, Y, Z three axial directions, and six degrees of freedom of rotational motion around X, Y, Z. In a mold formed of two or more parts, the pins are designed to accurately position adjacent parts of the mold.
A large amount of locating pins that are used for positioning part among the prior art assembly fixture, generally by the location polished rod, and set up the limit stop at location polished rod middle part and constitute, and different spare part, the size of mounting hole is also different, this just needs different locating pins to fix a position, need process out the pin of different diameters, its processing cost is high, too many pins are not well managed yet, the locating pin that has in addition all is the joint formula, it is not too firm at the fixed position in-process, will drop as long-time vibration, therefore can cause the unable normal use of some spare parts.
SUMMERY OF THE UTILITY MODEL
The utility model provides a mould locating pin that auto-lock performance is strong aims at solving the connection insecure that mentions in the above-mentioned background art, the problem of the locating hole of the multiple diameter of the unsuitable cooperation of locating pin.
The utility model is realized in such a way that the mould positioning pin with strong self-locking performance mainly comprises a fixing main body and a bolt main body;
the fixing main body comprises a fixing plate, a filling port is formed in the middle of the fixing plate, a filling inner cavity is fixedly connected to the bottom of the filling port, and an seepage hole is formed in the bottom of the filling inner cavity;
the bottom fixedly connected with bolt main part of fixed main part, the bolt main part includes the bolt post, the bottom fixedly connected with top of bolt post.
Preferably, the filling opening is rectangular.
Preferably, the plug is a plastic plug, and the plug is smooth and spherical.
Preferably, the number of the seepage holes is more than four, and the seepage holes are annularly distributed at the bottom of the filling inner cavity.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a mould locating pin that auto-lock performance is strong through setting up a plastics top, has effectively avoided the condition of locating pin scratch damage mould, and the bolt main part that sets up simultaneously has increased connection structure's fastness to fill the hot melt adhesive through oozing the hole and make the device connect more firmly, have fine laminating nature with the mould.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
1. Referring to fig. 1-2, the present invention provides a technical solution: a mould locating pin with strong self-locking performance comprises a fixing main body 1 and a bolt main body 2;
the fixing main body 1 comprises a fixing plate 11, a filling port 14 is formed in the middle of the fixing plate 11, a filling inner cavity 12 is fixedly connected to the bottom of the filling port 14, and an seepage hole 13 is formed in the bottom of the filling inner cavity 12;
the bottom of the fixing body 1 is fixedly connected with a bolt body 2, the bolt body 2 comprises a bolt column 21, and the bottom of the bolt column 21 is fixedly connected with a top head 22.
In this embodiment, fill mouth 14 both can be used for screwing the locating pin and carry out threaded connection with the mould, and the hot melt adhesive can fill inner chamber 12 by filling mouthful 14 entering again simultaneously, again by oozing in hole 13 gets into bolt main part 2 and mould threaded connection's gap, waits that the hot melt adhesive solidifies the back, can produce powerful fastening force and make mould and locating pin fixed connection.
Further, the filling opening 14 is rectangular, and the size of the rectangle is adapted to the size of a general screwdriver blade.
In this embodiment, the filling opening 14 facilitates the operator to screw into the positioning hole of the mold with a screwdriver, increasing the operability of the device.
Further, the plug 22 is a plastic plug, and the plug 22 is a smooth spherical shape.
In this embodiment, the plug 22 prevents the device from scratching the mold surface, effectively protecting the mold.
Further, the number of the seepage holes 13 is more than four, and the seepage holes 13 are distributed at the bottom of the filling cavity 12 in a ring shape.
In this embodiment, the plurality of bleed holes 13 facilitate the entry of the hot melt adhesive into the gap between the bolt body 2 and the mold for filling.
The utility model discloses a theory of operation and use flow: at first, a certain amount of hot melt adhesive is filled in the positioning hole, the positioning pin is screwed at the moment, so that the bolt main body 2 is in threaded connection with the die, then, the filling port 14 is filled with the hot melt adhesive, the hot melt adhesive enters a gap between the bolt main body 21 and the die through the seepage hole 13 to be filled, and the connection is finished after the hot melt adhesive is solidified.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
