Abstract
The invention discloses a dome piece injection mold, which comprises four cavities and runner. The four cavities are positioned on two sides of the runner in pair, a tangential lateral sprue is formed at the joint of the runner and each cavity, and the runner is arranged in an H shape; and the four cavities are arranged in a rectangle. According to the dome piece injection mold of the scheme, the runner is arranged in the H shape, and the tangential lateral sprue is formed at the joint of the runner and each cavity, so that the internal quality and the appearance quality of finished plastic parts are improved, the yield of a product is high, and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of dome spare injection mould, belong to the injection mold technical field.
Background technology
Dome spare injection mould in the prior art, comprise die cavity, running channel, die cavity has four both sides that are arranged in twos running channel, running channel is X-shaped and arranges, the cast gate that running channel and die cavity junction form and die cavity are 45 degree, and this kind dome spare injection mould moulding surface quality is very poor, the defectives such as serious snake flow liner, weld mark occur, therefore yield rate is low, increases production cost.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of dome spare injection mould, improved the moulding quality, yield rate is high.
Technical solution of the present invention is achieved in that a kind of dome spare injection mould, comprises die cavity, and running channel, described die cavity have four; Described four die cavities are positioned at respectively the both sides of running channel in twos, and described running channel and die cavity junction form the tangential direction side gate, and described running channel is the H type and arranges.
Preferably, described four rectangular arrays of die cavity.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of dome spare injection mould of the present invention, running channel are the H type to be arranged, and running channel and die cavity junction form the tangential direction side gate, have improved inherent quality and the presentation quality of plastic finished product, and the formed product rate is high, and has improved production efficiency.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of a kind of dome spare injection mould of the present invention;
Wherein: 1, die cavity; 2, running channel; 3, side gate.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1 is a kind of dome spare injection mould of the present invention, comprises die cavity 1, running channel 2, and described die cavity 1 has four, rectangular array; Described four die cavities 1 are positioned at respectively the both sides of running channel 2 in twos, and described running channel 2 forms tangential direction side gate 3 with die cavity 1 junction, and described running channel 2 is the H type and arranges.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
