Detailed Description
The invention will be further described with reference to the following examples.
The utility model relates to a no trace pipe fitting injection mold, as shown in fig. 1 to 6, including cover half 1, movable mould 2, cover half core 4 and movable mould core 3, cover half 1, movable mould 2, cover half core 4 and movable mould core 3 form the die cavity jointly, and cover half 1 is equipped with injecting glue mouth 5, through injecting glue mouth 5 intercommunication between die cavity and the hot runner 11, and cover half 1 is equipped with and is used for forming the bellmouth wall 6 of pipe fitting 10 bellmouth 12, injecting glue mouth 5 are established at bellmouth wall 6, because injecting glue mouth 5 is established at bellmouth wall 6, the space of injecting glue mouth 5 department is less, and when the injecting glue like this, the air impact area of contact that the die cavity was spouted into to the melten high pressure is little, is difficult to form the microbubble during injection molding of pipe fitting 10 to be difficult to produce.
The melten gel that gets into the die cavity at injecting glue mouth 5 can be divided into two strands of melten gels and separately through different routes, meets at the plane of symmetry of injecting glue mouth 5 at last, because this strand of melten gel is through different routes consequently the temperature when it meets can be different to form the weld mark easily and influence product appearance. In order to solve the problem, the mold cavity is of a plane-symmetric structure, the glue injection port 5 is symmetric with respect to one symmetric plane of the mold cavity, the inner wall of the mold cavity is provided with reinforcing rib grooves 7 for molding reinforcing ribs 8 of the pipe fitting 10, one of the reinforcing rib grooves 7 is arranged along the symmetric plane and is symmetric with respect to the symmetric plane, and the reinforcing rib groove 7 is located opposite to the glue injection port (as shown in fig. 5, the glue injection port is on the right side, the reinforcing rib groove 7 is on the left side, and thus the glue injection port 5 and the reinforcing rib groove 7 are arranged with the axial line opposite surface of the pipe fitting 10), so that the reinforcing ribs 8 (i.e. the reinforcing ribs 8 with shorter length shown in fig. 6) molded by the reinforcing rib grooves 7 shield weld marks formed in the injection molding process of the pipe fitting 10, and thus the weld.
In this embodiment, in order to make the air of die cavity discharge fast when moulding plastics, form the microbubble when reducing the casting product, reduce the production of gas line, strengthening rib recess 7 department is equipped with exhaust structure, because strengthening rib recess 7 at this symmetric position is when moulding plastics, strengthening rib recess 7 of die cavity department has the exhaust effect, reduces the production of gas line.
In this embodiment, the traceless pipe injection mold further comprises a demolding device 9, the demolding device 9 comprises a demolding baffle 91, the movable mold core 3 can reciprocate relative to the demolding baffle 91, when the pipe 10 is demolded, the movable mold core 3 is drawn back, the demolding baffle 91 stops the pipe 10 to move along with the movable mold 2, and therefore the pipe 10 is separated from the movable mold core 3, and demolding is achieved. Compare with current thimble demoulding structure, the utility model discloses a shedder 9 neither can scrape colored pipe fitting 10 surfaces, also the easier drawing of patterns. Preferably, the knockout device 9 further includes an oil cylinder 93, and the oil cylinder 93 drives the movable die core 3 to reciprocate. Preferably, there are a plurality of die cavities, the demolding device 9 further comprises a moving plate 92, each movable die core 3 is connected with the moving plate 92, a moving end of an oil cylinder 93 is connected with the moving plate 92, the oil cylinder 93 drives the moving plate 92 to reciprocate each movable die core 3, and only one oil cylinder 93 power source is needed to complete demolding of a plurality of pipe fittings 10.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and 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 technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
