SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to perfect above technical defect, provide the mould embryo structure of a removable mold core of an easy to use.
In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides a mould embryo structure of removable mold core, includes base and limiting plate, the inside rotation of base is equipped with first pivot, base one end installation be equipped with first pivot fixed connection's rotation handle, first pivot both ends are all fixed cover and are equipped with first bevel gear, the connection of base up end is equipped with the bottom suspension fagging, base and limiting plate both ends are rotated relatively and are equipped with the second pivot that runs through the bottom suspension fagging, the fixed cover in second pivot bottom connects and is equipped with the second bevel gear with first bevel gear engaged with, second pivot upside is equipped with the screw thread and cup joints the last backup pad that is equipped with the intercommunication and is equipped with the screw thread through-hole, it is equipped with the mold core to go up between backup pad and the bottom suspension fagging, mold core upper end and lower extreme all are equipped with spacing recess, it all is equipped with spacing lug to go up backup pad and bottom suspension fagging correspondence spacing recess.
Compared with the prior art, the utility model the advantage lie in: only need change the mold core during the use, need not change by a whole set of mould, go up the backup pad through rotatory turning handle and go up and down can realize taking and changing of mold core, thereby the setting up of spacing recess and spacing lug can make the mold core can not take place to squint and guarantee the stability of mould embryo.
As an improvement, the limiting groove is arranged from wide to narrow from outside to inside, and the accuracy of scarf joint between the limiting groove and the limiting convex block can be improved.
As an improvement, the surface of the holding end of the rotating handle is provided with grains, so that the friction force can be increased, and the sliding is not easy to occur and is more labor-saving.
As the improvement, the surface of the limiting convex block is provided with the rubber pad, so that the friction between the limiting convex block and the mold core can be reduced, and the service life is prolonged.
As the improvement, the lower supporting plate is internally provided with a connecting piece which is rotationally connected with the second rotating shaft, so that the second rotating shaft can rotate more smoothly and stably.
