Abstract
The utility model discloses a pin-point gate structure of an injection mould, which can be conveniently snapped from the root of a pin-point gate in injection molding, and comprises a pin-point gate bush, wherein the pin-point gate in the pin-point gate bush is communicated with a cavity of a mould, and is a full-taper cone-shaped hole. As the full-taper cone-shaped hole with consistent taper from head to tail, the pin-point gate provided by the utility model can be conveniently snapped from the root in the injection molding, so that the product precision is greatly improved; in addition, the cone-shaped hole can be processed by first adopting punching and then wire-electrode cutting. Since the advantages of the wire-electrode cutting such as greatly improving the finish degree and the precision of the pin-point gate, shortening the processing time, and improving the processing efficiency are well-known, only about one hour is needed to perform wire-electrode cutting to the cone-shaped holes of the moulds of plastic magnetic rotors in an indoor machine and an outer machine of a conversion air conditioner.
Description
Technical field
The utility model relates to injection molding, refers more particularly to the some pouring gate structure of injection molding.
Background technology
As everyone knows, injection molding all is provided with a cast gate.As shown in Figure 1, the some pouring gate structure of traditional injection molding comprises: be arranged on the some sprue bush 1 in the mould, the some cast gate in the some sprue bush 1 communicates with the die cavity of mould, and described some cast gate is made of the bellmouth 2 and the cylindrical hole 3 of mutual linking usually.Because it is cylindrical hole 3 that there is a straight section in the oral portion of hole irrigation, during injection moulding, differs and breaks from a cast gate root surely, thereby have influence on the product precision; In addition, this some cast gate adopts electric pulse processing usually, can not guarantee the fineness and the precision of bellmouth 2 and cylindrical hole 3, and process time is longer, is example with the mould of processing convertible frequency air-conditioner indoor and outdoor machine plastic magnetic rotor, and processing needs more than 20 hours.
The utility model content
Technical problem to be solved in the utility model is: be convenient to the injection molding point pouring gate structure broken from a cast gate root when a kind of injection moulding is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: injection molding point pouring gate structure, comprise: be arranged on the some sprue bush in the mould, the some cast gate in the some sprue bush communicates with the die cavity of mould, and described some cast gate is full tapering bellmouth.
The taper angle of described full tapering bellmouth is between 1 ~ 30 degree.
The beneficial effects of the utility model are: described in the utility model some cast gate is the full tapering bellmouth of tapering unanimity from first to last, and during injection moulding, the some cast gate is convenient to from root break, and has improved the product precision greatly; In addition, this bellmouth can adopt perforation back line cutting earlier that it is processed.As everyone knows, the line cutting processing can improve the fineness and the precision of a cast gate greatly, has shortened process time, has improved working (machining) efficiency, mould with processing convertible frequency air-conditioner indoor and outdoor machine plastic magnetic rotor is an example, and this bellmouth of line cutting processing only needs about 1 hour usually.
Description of drawings
Fig. 1 is the perspective view of the fabric width trimming device described in the background technology.
Among the figure: 1, some sprue bush, 2, bellmouth, 3, cylindrical hole.
Fig. 2 is the perspective view of fabric width trimming device described in the utility model.
Among the figure: 1, some sprue bush, 2, bellmouth.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 2, injection molding point pouring gate structure described in the utility model comprises: be arranged on the some sprue bush 1 in the mould, the some cast gate in the some sprue bush 1 communicates with the die cavity of mould, described some cast gate is full tapering bellmouth 2, and its taper angle is between 1 ~ 30 degree.
During making, adopt perforation back line cutting earlier that described full tapering bellmouth 2 is processed.As everyone knows, the line cutting processing can improve the fineness and the precision of a cast gate greatly, has shortened process time, has improved working (machining) efficiency.
Claims (2)
