Intelligent core-pulling die
Technical field
The present invention relates to the technical field of mould, is especially a kind of intelligent core-pulling die.
Background technology
At present, the upper majority of in life or production can use plastic products, and a big chunk reason is because they are easy
One-shot forming is into complicated shape, than product 1 as shown in Figure 1, although it is a simple product, in U-shaped bottom
Through hole 1-1 is additionally provided with, therefore, the ejection action of the core pulling action of through hole and product can be arranged to enter simultaneously in mold design
OK.But this mould structure has the drawback that:On the one hand, because the stripping direction of product is vertical direction, therefore produce
Product are when taking out, it is necessary to and it is that vertical direction takes out product, so, the opening stroke of upper mould will be designed to very greatly,
In order to which operating personnel are taken out product, and opening stroke is bigger, molds that the specification of drive cylinder is bigger, and other corresponding zero
The size and specification of accessory be also just designed to it is bigger so that the cost of production equipment is higher;On the other hand, mould molding takes off
Mould typically manually takes out, and the hand of operating personnel will be intervened in mould, causes certain potential safety hazard, while production efficiency
Lowly.
The content of the invention

The course of work of the intelligent core-pulling die of the present invention is as follows:When upper mould 2 molds, drive cylinder 18 starts to start, driving
No.1 drive rod 11 rotates to the right, and then drives No. two drive rods 12 to depart from escapement 17 again while moving right,
So that No. two drive rods 12 are swung, one end away from drive cylinder 18 is lifted up, and forces No. three drive rods 13 upward
It is mobile, under the transmission of rack-and-pinion, the push rod in ejecting mechanism is moved upwards, so as to ejecting product 1.Core bar side simultaneously
No. two drive rods 12 press downwards, the bottom of core bar 27 lose limitation after force core bar 27 downward in the presence of core bar spring 25
It is mobile, so that the upper end of core bar 27 extracts through hole 1-1 out.When above-mentioned action is fully finished, product 1 ejects lower mould by push rod, leads to
Hole 1-1 core pullings terminate, and now on escapement 17 No. four drive rod 14 rotates with the rotation of escapement 17, until No. five drives
One end of lever 15, link gear start to act.The rotation of itself occurs for No. five drive rods 15, makes the company being connected with rack-plate 10
Connect end to be lifted up, rack-plate 10 is driven upward motion, and in the presence of the first driving gear set 5, product knock-pin 4 is to the left
Move horizontally, so that by the ejection die of product 1, so far realize whole actions of automatic core-pulling blanking.
It is described above, only it is preferably feasible implementation example of the invention, it is impossible to therefore limit to the interest field of the present invention,
For those skilled in the art, it is all made with technical scheme and technical concept other are various corresponding
Change should all belong within the protection domain of the claims in the present invention.
