The utility model discloses a following mode realizes a novel advance injection mold of annular laser radar dustcoat of gluey mode, its characterized in that: including movable mould core and cover half core, a cylindrical recess has been seted up on the lower surface of movable mould core, be provided with a cylindrical lug on the upper surface of cover half core, highly being less than of cylindrical lug the degree of depth of cylindrical recess, the bottom surface area of cylindrical lug is less than the bottom surface area of cylindrical recess makes movable mould core with the closed die cavity that forms a bowl form of cover half core, the middle part of movable mould core is provided with one and runs through the runner of movable mould core, the runner with the die cavity is linked together, be provided with the ejector pad that is used for releasing the laser radar dustcoat after moulding plastics on the cover half core.
Further, the thickness of the cavity is 1-2 mm.
Furthermore, a groove is formed in the upper surface of the cylindrical groove, and the groove is located right below the flow channel.
Furthermore, the push block is annular, the inner diameter of the push block is smaller than the outer diameter of the bottom surface of the cavity, and the inner diameter of the push block is larger than the inner diameter of the bottom surface of the cavity.
The beneficial effects of the utility model reside in that: the utility model discloses directly advance gluey through the runner, increase top cap structure at the process of moulding plastics annular laser radar dustcoat, strengthened the structural strength and the dimensional stability of whole laser radar dustcoat, reduce and warp, follow-up mode through the machine finishing impression processing is got rid of this structure of top cap, and this kind of mode advances gluey, and the product that obtains after moulding plastics is more stable.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 3 to 4, in an embodiment of the present invention, an injection mold of an annular laser radar housing with a novel glue feeding mode is characterized in that: the laser radar outer cover mould comprises a movable mould core 1 and a fixed mould core 2, wherein the movable mould core 1 is a laser radar outer cover product outer surface mould cavity, the fixed mould core 2 is a laser radar outer cover product inner surface mould cavity, a cylindrical groove 3 is formed in the lower surface of the movable mould core 1, a cylindrical lug 4 is arranged on the upper surface of the fixed mould core 2, the height of the cylindrical lug 4 is smaller than the depth of the cylindrical groove 3, the bottom area of the cylindrical lug 4 is smaller than the bottom area of the cylindrical groove 3, so that the movable mould core 1 and the fixed mould core 2 are closed to form a bowl-shaped mould cavity 5, the thickness of the mould cavity 5 is 2mm, a flow channel 6 penetrating through the movable mould core 1 is arranged in the middle of the movable mould core 1, the flow channel 6 is communicated with the mould cavity 5, and molten plastic flows into the mould cavity 5 through the flow channel 6, and a push block 7 for pushing out the laser radar outer cover after injection molding is arranged on the fixed mold core 2. The pushing block 7 is pushed by an ejector plate and an ejector fixing plate, the ejector plate and the ejector fixing plate are general structures on an injection mold, and are not shown in the figure, and the ejector plate and the ejector fixing plate apply power sources through an injection molding machine. After the injection molding is finished, the laser radar injection molding product 8 is pushed out by the push block 7, so that the laser radar injection molding product 8 is separated from the fixed mold core 2, after finishing the subsequent processes such as surface treatment and the like, the fine engraving treatment is finally carried out through a machine, and the top cover of the laser radar injection molding product 8 is removed to obtain the annular laser radar outer cover 9.
Referring to fig. 1, in an embodiment of the present invention, a groove 10 is disposed on an upper surface of the cylindrical groove 3, and the groove 10 is located under the runner 6, so as to balance a pulling force of the runner 6 when the injection mold is opened, and prevent the laser radar injection molding 8 from being stuck on the movable mold core.
Referring to fig. 1, in an embodiment of the present invention, the push block 7 is in a circular ring shape, the inner diameter of the push block 7 is smaller than the outer diameter of the bottom surface of the cavity 5, and the inner diameter of the push block 7 is larger than the inner diameter of the bottom surface of the cavity 5, so that when the laser radar injection molding 8 is pushed out by the push block 7, the laser radar injection molding 8 is pushed out by the uniform force applied to the laser radar.
Referring to fig. 5, it is worth mentioning that the laser radar products have different glue feeding methods, and the size difference is mainly represented by A, B, C. The diameter deviation of the injection-molded annular laser radar product A is controlled within plus or minus 0.1, and the diameter deviation of the injection-molded annular laser radar product B is controlled within plus or minus 0.1. If the glue is fed in a point glue feeding mode, the deviation of A, B, C three dimensions of the product can be controlled to be plus or minus 0.3; and the utility model discloses a go into the deviation homoenergetic of the three size of A, B, C homoenergetic control of the laser radar product of the area top cap that the mode obtained within plus-minus 0.05. Consequently, compare in the product that the mode of glue injection was moulded plastics of point notes, the utility model discloses a product that the mode of glue injection was moulded plastics has promoted intensity, reduces the deformation of product, has promoted the efficiency of moulding plastics of product.
The utility model discloses a theory of operation does: molten plastic flows to the die cavity through the runner in, treats that the plastic shaping back, opens the injection molding machine, and the fixed mold core is opened with the movable mold core along the injection molding machine, obtains laser radar injection molding, and ejector pad through on the fixed mold core is ejecting with laser radar injection molding, and breaks away from the fixed mold core, after accomplishing back processes such as surface treatment, carries out the finishing impression through the machine at last and handles, gets rid of laser radar injection molding's top cap, obtains annular laser radar dustcoat.
The above is only the preferred embodiment of the present invention, and all the equivalent changes and modifications made according to the claims of the present invention should be covered by the present invention.
