Abstract
The utility model discloses a novel gasping pin, which comprises a connection rod, one end of which is fixed to an upper fixed plate of a mould, and the connection rod passes through a mould cavity to extend to a mould flow passage; the other end of the connection rod is provided with a joint, the joint is arranged inside the mould flow passage and can be joined with the flow passage during the molding process; a flange is arranged between the joint and the connection rod; a concave surface is respectively arranged between the flange and the joint and between the flange and the connection rod, so that the flow passage can wrap the joint and the flange; the joint, the flange and the flow passage present a saw shape, so that the flow passage can be closely contacted with the joint; the design of the gasping pin is novel, and the gasping pin is applicable to all rubber moulds and the moulds with long and large flow passage and large drawing force, and has obvious effect on the taking function of the flow passage.
Description
Technical field
The utility model relates to a kind of material grasping pin, particularly relates to a kind of material grasping pin of drawing great efforts.
Background technology
As shown in Figure 1, material grasping pin 30 shapes of rubber pattern three template die runners are before, one connecting rod 31, these connecting rod 31 1 ends are connected with a globe joint 32, and this joint 32 forms a concave surface 320 with being connected the connecting place intermediate recess, during matched moulds, rubber system runner 33 can combine with this concave surface 320, and with joint 32 parcel (as shown in Figure 2), make in die sinking, to draw this material grasping pin 30, can with rubber system runner 33 together drawing go out mold runner.
But because rubber is softer, material grasping pin 30 is difficult for three template die runners are grabbed out from template when die sinking; By the die trial repeatedly of rubber three template dies, material grasping pin 30 can not be pulled out rubber system runner 33 fully from template, and the sphere of material grasping pin 30 is strengthened and runner is strengthened polishing effect is not clearly.Need manually runner to be extracted from template, strengthened labour intensity like this, and need long molding cycle, greatly reduce production efficiency.
Summary of the invention
The utility model proposes a kind of novel material grasping pin of drawing great efforts, solved the problem of runner disengaging runner difficulty.
Technical solutions of the utility model are: a kind of novel material grasping pin, and it comprises:
One connecting rod, the one end is fixed in the upper mounted plate of mould, and this connecting rod passes die cavity, extends to arrive mold runner;
One joint, its setting are connected in this connecting rod other end, are arranged in mold runner, can engage with runner in forming process; Between this joint and this connecting rod, be provided with a bead; This bead in joint, bead between connecting rod, respectively be formed with a concave surface; Since this two concave surface, and make that runner can be with this joint and bead parcel.
This novel material grasping pin is to increase concave surface by bead is set, and makes runner and material grasping pin contacts area strengthen, and reaches to increase the purpose of material grasping pin to runner pulling capacity degree.

Fig. 6 is this novel material grasping latch structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail.
Fig. 3 is that this novel material grasping pin combines the matched moulds schematic diagram with mould, as shown in the figure, this mould is rubber pattern three template dies 10, this novel material grasping pin 20 is provided with, one connecting rod 21, these connecting rod 21 1 ends are fixed in the upper mounted plate 11 of three template dies 10, and this connecting rod 21 extends through upper mounted plate 11 and stripper plate 12, arrive rubber runner 130 limits.
One joint 22, these joint 22 diameters are identical with this connecting rod 21, and its setting is connected in this connecting rod 21 other ends, is arranged in three template dies, 10 rubber runners 130, can engage with rubber runner 130 in forming process; Between this joint 22 and this connecting rod 21, be provided with a bead 23, these bead 23 diameters are directly identical with this joint 22 and connecting rod 21; This bead 23 in joint 22, bead 23 between connecting rod 21, respectively be formed with a concave surface, and make toothing (as shown in Figure 6) between this joint 22, bead 23, connecting rod 21 threes; Rubber runner 130 can be with this joint 22 and bead 23 parcels, because this two concave surface 230, rubber runner 130 becomes big with these joint 22 contacts area, and zigzag makes this rubber runner 130 contact with joint 22 closely, thereby material grasping pin 20 can produce bigger drawing dynamics to rubber runner 130.
This kind bead 23 can be provided with a plurality of, and concave surface 230 quantity also can increase simultaneously, and it is tightr to make that rubber runner 130 contacts with material grasping pin 20 joints 22, and this joint 22 can produce bigger pulling capacity to rubber runner 130.
Fig. 4 is that this novel material grasping pin 20 combines die sinking first time schematic diagram with mould, and as shown in the figure, this three template die 10 upper mounted plates 11 together separate with lower bolster 13 with stripper plate 12, and material grasping pin 20 can engage closely rubber runner 130 and pull out from lower bolster 13.
Fig. 5 is that this novel material grasping pin 20 combines die sinking second time schematic diagram with mould, and as shown in the figure, die sinking for the second time is a fixed head 11 and the separating of stripper plate 12; This rubber runner 130 is because the stopping of stripper plate 12, and is forced to and this material grasping pin 20 joints 22 break away from, and makes this rubber runner 130 break away from three template dies 10 smoothly.
This novel material grasping pin 20 makes zigzag into by the shape with rubber three template dies 10 material grasping pins 20, material grasping pin 20 zigzag fashions are stretched in the rubber runner 130 fully, the pulling capacity of 20 pairs of rubber runners 130 of sawtooth material grasping pin increases, three template dies 10 draw the material pin smoothly three template dies, 10 runners to be pulled out in template fully when first time die sinking, this material grasping pin 20 is simple in structure, processing is also convenient, has improved production efficiency greatly.
