Detailed Description

In order to make the utility model realize that technical means, creation characteristics, achievement purpose and effect are clearer and easily understand, it is right to combine below the figure and the detailed implementation mode the utility model discloses do further explanation:

as shown in the figures 1-4 of the drawings,

the utility model provides an umbrella rib injection mold, includes cover half 1, movable mould 3, pre-buried pole 2 is installed in the cover half 1, cover half 1 includes: a first accepting groove 12, second accepting groove 16 for buffering injection molding material, it is used for injecting the hole 13 of moulding plastics to open in first accepting groove 12, the second accepting groove 16, offer on the cover half 1 and be used for forming the shaping groove 18 of rib, and set up respectively the first piece 11 and the second that support at shaping groove 18 both ends support and hold piece 15, two pouring runners 14 are seted up at cover half 1 top, pouring runner 14 intercommunication cover half 1 one end the hole 13 of moulding plastics the one end of shaping groove 18 is provided with jacking piece 17 that the jacking was used when the drawing of patterns, the middle part of cover half 1 be provided with the lower locating hole 19 of last locating hole 32 matched with in movable mould 3 middle part.

In the rib injection mold, during production, the embedded rod 2 is placed in the fixed mold 1, the lower positioning hole 19 of the fixed mold 1 is matched with the upper positioning hole 32 of the movable mold 3 for positioning, then the movable mold 3 and the fixed mold 1 are controlled to be matched, after the matching is finished, injection molding materials are sprayed into the injection molding holes 13 under the action of large pressure, the injection molding materials are buffered by the first accommodating groove 12 and the second accommodating groove 16, so that the injection molding materials stably enter the pouring runner 14, and the pouring runner 14 is connected with all the injection molding holes 13 at one end of the fixed mold 1 and the molding groove 18, so that the injection molding materials can be filled into the whole mold cavity through the pouring runner 14.

In the above, the embedded rod 2 is produced by injection molding of the same material.

In the production process of the umbrella ribs, when the strength of the umbrella ribs is increased by using the embedded parts, the embedded rods 2 are made of the same material as the injection molding material, so that the weight of the umbrella ribs cannot be increased.

As described above, the embedded rod 2 is placed in the molding groove 18 and fixed by the first abutting block 11 and the second abutting block 15.

The distance between the first abutting block 11 and the second abutting block 15 is just the same as the length of the embedded rod 2, so the embedded rod 2 can be fixed in the molding groove 18, and the injection molding material does not affect the position of the embedded rod 2.

As described above, the movable mold 3 includes the connecting groove 31, the upper positioning hole 32 is disposed in the connecting groove 31, and the connecting groove 31 is perpendicular to the pouring runner 14.

Since the connecting groove 31 is perpendicular to the pouring runner 14, the rib can be smoothly released from the movable mold 3 during demolding.

As mentioned above, the upper positioning hole 32 is vertical to the connecting groove 31.

Since the upper positioning hole 32 is in the connecting groove 31 and perpendicular to the connecting groove 31, the rib can be smoothly released from the movable mold 3 during demolding.

As mentioned above, every two forming grooves 18 are in a group, and the two ends of the group are respectively provided with the first receiving groove 12 and the second receiving groove 16.

Because each group all contains two holding tanks, namely each group contains two injection molding hole 13, so the injection molding material gets into evenly, and filling is fast, and the part takes shape soon.

In the above, the contact surface of the fixed die 1 and the movable die 3 is tightly attached.

Because the contact surface of the fixed die 1 and the movable die 3 is tightly attached, the stability during die assembly can be ensured, and the reject ratio of products is reduced.

In the above, the bottom surface of the end of the forming groove 18 far away from the jacking block 17 is arc-shaped.

The bottom surface of one end of the forming groove 18, which is far away from the jacking block 17, is arranged to be in an arc shape, so that the jacking mechanism can smoothly push out a formed piece after demoulding.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
