Abstract
The invention provides a sliding block core-extracting device of a lock core die-casting mold. When extracting the core, a locking piece groove is firstly extracted, and two side faces of the lock core are extracted finally, so that the device is easier to separate the product and prevents the mold from being damaged since the locking piece groove is pulled to be scratched. The device comprises an upper mold, a lower mold, two sliding blocks, a plurality of inclined pins and a plurality of safety pins, wherein the sliding blocks are arranged in a lower mold cavity, the sliding blocks are provided with a plurality of inclined pin holes, the inclined pins and the inclined pin holes are matched with each other to be arranged on the upper mold, the inclined pins are in the shape of V, and the safety pins are inserted into the sliding blocks. The device is characterized in that the lower mold cavity is further internally provided with the other sliding block, and the two sliding blocks are sequentially arranged with each other at a certain distance.
Description
Technical field
The present invention relates to the technical field of compression mod, be specially a kind of lock core compression mod slide block core-pulling device.
Background technology
Lock core in forming process since the product two sides fully in slide block, add that the upper collet groove is more, package power is big, product is bonded in the slide block easily, existing core pulling method is seen Fig. 1, when dividing mould, taper pin 1 drives 2 pairs of locking plate grooves of slide block and loose core simultaneously in the lock core two sides, causes the locking plate groove to be pulled, and has pressing mold hidden danger.
Summary of the invention
At the problems referred to above, the invention provides a kind of lock core compression mod slide block core-pulling device, it is when loosing core, and the locking plate groove is difficult for being pulled, and the probability that press mold hidden danger occurs is very little.
Its technical scheme is such: a kind of lock core compression mod slide block core-pulling device; it comprises upper die and lower die, slide block, taper pin and safety plug; described slide block is arranged in the counterdie die cavity; the taper pin hole is arranged on the described slide block; described taper pin cooperates with described taper pin hole and is installed on the described patrix, and described taper pin is V-shaped, and described safety plug inserts in the slide block; it is characterized in that: also be provided with a slide block in the described counterdie die cavity in addition, described two slide blocks maintain a certain distance in order to install.
It is further characterized in that: described slide block, taper pin and safety plug are that the center is symmetrical arranged with the part model hole in described counterdie die cavity.
In the said structure of the present invention, the counterdie die cavity is interior owing to be provided with the slide block that maintains a certain distance in order to install with slide block, taper pin drives slide block earlier to carry out loosing core the first time, the drive slide block carried out loosing core the second time after slide block touched another slide block, take out the locking plate groove earlier, take out the two sides of lock core again, with regard to easier product is separated like this, prevent that the locking plate groove from pulling, eliminated pressing mold hidden danger.
Description of drawings
Fig. 1 is existing lock core compression mod slide block core-pulling device structural representation;
Fig. 2 is a lock core compression mod slide block core-pulling device structural representation of the present invention.
The specific embodiment
See Fig. 2, the present invention includes patrix 1, counterdie die cavity 8, order is equipped with slide block separated by a distance 2 respectively in 7 both sides, part model hole, 4, taper pin hole 5 is arranged on the slide block 4, taper pin 6 cooperates with taper pin hole 5 and is installed on the patrix 1, taper pin 6 is V-shaped, and safety plug 3 inserts in the slide block 2, slide block 2,4 are arranged in the counterdie die cavity 8, when dividing mould, patrix separates, and drives taper pin 6 and safety plug 3 and moves upward, the V-arrangement face extruding slide block 4 of taper pin 6, realize loosing core for the first time, loosing core of locking plate groove, when slide block 4 contacted with slide block 2, taper pin 6 continued up, taper pin 6 drives slide block 4 extruding slide blocks 2, realize loosing core for the second time, take out the two sides of lock core again, with regard to easier product is separated like this, prevent that the locking plate groove from pulling, eliminated pressing mold hidden danger.
Claims (2)
