Abstract
The utility model discloses a conical plastic lens injection sprue which comprises an injection sprue body, wherein the injection sprue body is in a shape of a hollow cone; openings are formed in two ends of the injection sprue body; the opening diameter of one end with a large opening is 2-3mm, and the opening diameter of one end with a small opening is 0.9-1.5mm; the injection sprue body is 1-15mm long and is made of a transparent plastic material. The conical plastic lens injection sprue has the beneficial effects of practicability, low production cost and convenience in use; the pressure can be increased as the diameter of the sprue is relatively small; meanwhile, by virtue of the design of the conical sprue, the number of plastic raw materials in the conical plastic lens injection sprue is relatively large, so that the condensation of the plastic raw materials in advance can be prevented.
Description
Technical field
The utility model relates to a kind of lens injection molding sprue, particularly a kind of conical plastics lens injection molding sprue.
Background technology
Optical plastic lens is one of main optical element of taking a picture, making a video recording in instrument, the forming method of optical plastic lens will rely on metal die, design and manufacturing technology to mould and plastics forming technique require quite high, and in the injection moulding process of optical plastic lens, the design of cast gate is one of crucial technical problem.The moulding of optical spherical surface plastic lens must be passed through feed supplement pressure maintaining period, in feed supplement pressure maintaining period, must continue up to cast gate solidify till; The problem that prior art exists is: if cast gate is too little, although can guarantee that the pressure of injection hole is larger, make pressurize effect better, it is very fast that temperature reduces, and plastics are solidified comparatively fast; Cast gate is too large, and the pressure of injection hole is less, pressurize effect is poor.
Utility model content
This practical technical problem to be solved is for the deficiencies in the prior art, and a kind of novel conical plastics lens injection molding sprue is provided.
To achieve these goals, the measure that the utility model is taked:
A kind of conical plastics lens injection molding sprue, comprise injection molding sprue body, described injection molding sprue body is a hollow cone, injection molding sprue body both ends open, the opening diameter of the larger one end of opening is 2～3mm, the opening diameter of the less one end of opening is 0.9～1.5mm, and the length of injection molding sprue body is 1～15mm;
Described injection molding sprue body is made with transparent plastic material.
The beneficial effects of the utility model: practicality, production cost is low, easy to use, and gate diameter is less, can improve pressure, and simultaneously conical cast gate design, can make inside, and plastic raw materials is more, can prevent that plastic raw materials from shifting to an earlier date condensation.
Accompanying drawing explanation
Fig. 1 is use state plane structural representation of the present utility model.
The specific embodiment
A kind of conical plastics lens injection molding sprue, comprise injection molding sprue body 1, described injection molding sprue body 1 is a hollow cone, injection molding sprue body 1 both ends open, the opening diameter of the larger one end of opening is 2～3mm, the opening diameter of the less one end of opening is 0.9～1.5mm, and the length of injection molding sprue body 1 is 1～15mm; Described injection molding sprue body 1 use transparent plastic material is made.
When using, the less one end of injection molding sprue body 1 opening is connected to mould, injection molding sprue body 1 is a hollow cone, adopt conical design, in feed supplement process, feed supplement packing stage is because an end opening is less, and osculum ftercompction can guarantee that pressure is larger, ftercompction effect is better, and can not solidify, be conical structure simultaneously, and the plastic material in injection molding sprue body 1 is more, can prevent plastics condensation, thereby realize the purpose of this utility model.
Claims (2)
