The blank is formed into a tool with a specific shape and size under the action of external force. And all be equipped with a lot of guide rails in the mould, the guide rail all is fixed on the body of mould through the locating pin, and when the guide rail goes wrong or with the guide rail dress mistake when needing to install again, need follow the mould body with the locating pin and dismantle.
In the traditional positioning pin disassembly, a screw needs to be clamped by a locking pliers and screwed tightly in a screw hole of the positioning pin, the positioning pin is pulled out through manual force, but in the process of pulling out the positioning pin, the angle of the positioning pin deflects, so that the hole of a main die body for installing the positioning pin and the screw hole on the positioning pin are damaged; when the guide rail is installed again, the positioning pin is usually directly knocked into the hole of the die body by using the copper rod, and the angle of the positioning pin is also deflected in the knocking process, so that the hole of the die body for installing the positioning pin and the screw hole in the positioning pin are damaged to some extent, and the positioning pin is also damaged to some extent due to the fact that the copper rod directly knocks the positioning pin.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem and providing a puller which is high in guide rail dismounting efficiency and can prevent the damage of a positioning pin.
The technical scheme of the utility model is that:
the utility model provides a puller for dismouting of mould locating pin, includes slide bar, dog, connector, slider and pull head, sliding connection has the slider on the slide bar, the dog has been linked firmly to the one end of slide bar, the other end of slide bar links to each other with the one end of connector, the inside screw hole that has of the other end of connector, the connector passes through the screw hole links to each other with the pull head, the pull head includes a body coupling's connector link, pull head main part and locating pin link, all have the external screw thread on connector link and the locating pin link, the connector link passes through the screw hole on the connector and links to each other with the connector.
Preferably, the slider is the cylinder, just the middle part of slider is equipped with a through-hole, the slider passes through-hole sliding connection on the slide bar, and the width of dog is greater than the diameter of slider, and the width of connector is greater than the diameter of slider through-hole.
Preferably, both ends of the slider are chamfered.
Preferably, the connector can be connected with different types of pulling heads according to different types of positioning pins.
The utility model has the advantages and the beneficial effect
The utility model discloses a slider is the repetitive motion on the slide bar to hit and beat the dog and drive the locating pin and remove to the direction of keeping away from the mould body, thereby make the locating pin extract in the mould body, when needs installation locating pin, only need to hit the slider repetitive motion on the slide bar, thereby make the slider hit repeatedly and beat the connector, the connector drives the locating pin and removes in to the mould body, thereby make the slide rail install on the mould body through the locating pin, through the utility model discloses can effectively avoid because of artifical deflection of dismantling with the in-process locating pin angle to the dismantlement of locating pin and installation, thereby lead to the screw hole on the hole of mould main part installation locating pin and the locating pin to have the phenomenon of damaging, avoided more because of the phenomenon that leads to the damage of locating pin is beaten of copper bar to the locating pin to can effectively improve the dismantlement efficiency of guide rail.
