Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, fig. 2 and fig. 3, the automobile pipe fitting mold with the rapid demolding structure comprises a workbench 1, a molding rear mold 101 is fixedly mounted on one side of the upper surface of the workbench 1, a cylinder 102 is fixedly mounted on the other side of the upper surface of the workbench 1, and a molding front mold 103 is fixedly mounted at the output end of the cylinder 102.

A rear mold insert 104 is fixedly mounted on one side of the rear molding mold 101 close to the front molding mold 103, and an injection molding hole 105 is formed in the surface of one side of the front molding mold 103 in a penetrating manner.

The surface of one side of the rear mold insert 104, which is close to the molding front mold 103, is provided with a molding cavity 106, a rubber coating prefabricated member 2 is arranged in the molding cavity 106, one end of the rubber coating prefabricated member 2 is inserted with a hose 3 for conveying gas, and one end of the hose 3 extends to the outside of the molding cavity 106. The hose 3 is a bellows.

A delivery pipe 4 is inserted into a pipe orifice at one end of the hose 3, and a connection pipe 401 is fixedly arranged at one end of the delivery pipe 4 far away from the hose 3. The worker plugs the encapsulation prefabricated part 2 with one end inserted with the hose 3 into the forming cavity 106, then plugs the conveying pipe 4 with the hose 3, then starts the cylinder 102, enables the forming rear mold 101 to be tightly attached to the forming front mold 103, then the worker uses the injection molding equipment to perform injection molding through the injection molding hole 105, after injection molding is completed, the worker controls the output end of the cylinder 102 to retract, enables the forming front mold 103 to move to the original position, the injection molded product sleeve is arranged at one end of the hose 3, then the worker connects the connecting pipe 401 with the blowing equipment, then starts the blowing equipment, and enables gas to blow the product through the hose 3, so that the injection molded product falls off from one end of the hose 3 under the action of air pressure, compared with the mode of ejecting the ejector rod, the transmission speed of the gas in the hose 3 is high, the time required by demolding is greatly reduced, and the production efficiency is improved.

As shown in fig. 3, 5, 6, and 7, in this embodiment, a connecting plate 5 is sleeved on one side of a tube body of the connecting tube 401, two mounting brackets 501 are fixedly mounted on one side of the connecting plate 5 close to the hose 3, a bidirectional threaded rod 502 is rotatably mounted between the two mounting brackets 501, two moving brackets 503 are respectively screwed on two sides of the shaft of the bidirectional threaded rod 502, arc-shaped clamping plates 504 are respectively fixedly mounted on two opposite sides of the two moving brackets 503, and one end of the bidirectional threaded rod 502 penetrates through the corresponding mounting brackets 501 and is fixedly mounted with a rotating wheel 5021. A positioning rod 505 is fixedly mounted between the two mounting brackets 501, and the two movable brackets 503 are respectively slidably disposed on two sides of a rod body of the positioning rod 505. After the staff pegged graft hose 3 and conveyer pipe 4 mutually, rotate runner 5021 and make two-way threaded rod 502 rotate, two arc splint 504 of mode drive along locating lever 505 direction relative movement of pivoted two-way threaded rod 502 through the screw precession to make two arc splint 504 press from both sides the tight conveyer pipe 4 surface of hose 3 one end clamp, avoid hose 3 to drop from conveyer pipe 4 surface under high-pressure gas's effect.

As shown in fig. 6, it should be noted that rubber plates are fixedly mounted on opposite sides of the two arc-shaped clamping plates 504. Through setting up the rubber slab, increased the frictional force between arc splint 504 and the hose 3 for when arc splint 504 presss from both sides tightly hose 3, hose 3 is difficult for droing more.

The working principle of the automobile pipe fitting mold with the rapid demolding structure is as follows:

during the use, the staff packs in the shaping chamber 106 with the encapsulation prefab 2 of hose 3 of pegging graft in one end, later peg graft conveyer pipe 4 and hose 3 mutually, start cylinder 102 after that, make shaping back mould 101 closely laminate with shaping front mould 103, the staff uses injection moulding equipment to mould plastics through injection moulding hole 105, after the completion of moulding plastics, the staff controls cylinder 102 output and contracts, make shaping front mould 103 remove to the normal position, the product cover of injection moulding at this moment overlaps in hose 3 one end, the staff is connected connecting pipe 401 with the gas blowing equipment, start the gas blowing equipment afterwards, make gas blow the product through hose 3, thereby make the product of injection moulding drop from hose 3 one end under the effect of atmospheric pressure, compare with ejector pin ejecting mode, because the transmission rate of gas in hose 3 is faster, thereby greatly reduced the required time of the drawing of patterns, and the production efficiency is promoted.

The above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not limitations of the embodiments of the present invention, and for those skilled in the art, other variations or changes of different forms can be made on the basis of the above description, and it is not exhaustive here that all embodiments can be given, and all obvious variations or changes are still included in the protection scope of the present invention.
