Embodiment Construction

[0049] In order to further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0050] Such as Figure 2-5 As shown, this application provides:

[0051] A mechanical break gate structure, including a stripping plate 2 and a female formwork 3, the stripping plate 2 is provided with a material head male mold 4 on the side facing the mother formwork 3, and the material head master mold is provided on the side of the female formwork 3 facing the stripping plate 2 5. The gap between the material head male mold 4 and the material head female mold 5 forms a cavity, and the stripping plate 2 is provided with a rough mouth flow channel 6 extending from the side of the stripping material plate 2 away from the mother template 3 to the cavity, The side of the mother template 3 away from the ...

Abstract

The invention relates to the field of cutting devices for gates or inner gates in injection molds, in particular to a mechanical gate cutting structure which comprises a stripper plate and a female mold plate, a stub bar male mold is arranged on the face, facing the female mold plate, of the stripper plate, and a stub bar female mold is arranged on the face, facing the stripper plate, of the female mold plate. A cavity is formed in a gap between the stub bar male die and the stub bar female die, a thick opening runner extending to the cavity from the face, away from the female die plate, of the stripping plate is arranged on the stripping plate, a product female die is arranged on the face, away from the stripping plate, of the female die plate, and a thin opening runner penetrating through the female die plate and communicating the outer side of the product female die and the cavity is arranged on the female die plate. The mechanical sprue breaking structure further comprises an inverted buckle arranged between the stripper plate and the female mold plate, and the execution end of the inverted buckle is attached to the stub bar female mold and inserted into the cavity. The problem of how to automatically break a stub bar and a product during mold opening is solved, meanwhile, the stub bar is separated from the stripper plate and the female mold plate, and the mechanical sprue breaking structure is simple in structure and convenient to operate. And the material head is automatically separated from the mold.

Description

technical field [0001] The invention relates to the field of a gate or ingate cutting device in an injection mold, in particular to a mechanical gate breaking structure. Background technique [0002] Such as figure 1 As shown, the three-plate mold has two parting surfaces, the injection mold is divided into three parts, and the nozzle plate 1b is added between the A plate 1a and the B plate 1c, which is suitable for occasions where there are no traces of the gate around the product. This kind of mold adopts point gate, so the three-plate mold is also called fine gate mold. Plate A is also called stripping plate, nozzle plate is also called mother formwork, plate B is also called male formwork, and runner is also called material head. [0003] When the mold is opened, the A plate 1a is separated from the nozzle plate 1b first, the connection part between the runner 1d and the product 1e is broken, the runner 1d falls off from the A plate and the nozzle plate 1b, and then th...
