Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1:

referring to fig. 1 to 4, the injection mold facilitating injection of a raw material in the present embodiment includes: the die comprises a die body 1, wherein an upper die plate 2 is arranged at the top of the die body 1, specifically, the upper die plate 2 is fixedly connected with the die body 1, a sprue 3 is arranged in the upper die plate 2, specifically, the sprue 3 is fixedly connected with the upper die plate 2, a runner 4 is arranged in the sprue 3, a plurality of clamping mechanisms 5 which are distributed in central symmetry are arranged in the runner 4,

clamping mechanism 5 includes pivot 6 with runner 3 fixed connection, and the surface rotation of pivot 6 is connected with fixed block 8, is equipped with torsion spring 7 between fixed block 8 and the pivot 6, and torsion spring 7's both ends respectively with fixed block 8 and pivot 6 fixed connection, the bottom fixedly connected with liftout plate 9 of fixed block 8, and the bottom of liftout plate 9 is equipped with ejecting chamber 13.

When carrying out injection moulding to lamp stand injection molding, insert injection head of injection machine in injection mold's runner 3, and insert the top of fixed block 8, when injection head inserts runner 4 of 3 inside of runner, torsion spring 7 drives fixed block 8 and presss from both sides the tight injection head, begin to inject the raw materials of moulding plastics (be molten plastic) at the injection machine, and the raw materials of moulding plastics fills up the back in the mould completely, then reach ejection plate 9, ejecting ejection plate 9 again, make ejection plate 9 drive fixed block 8 rotate under the effect of pivot 6, directly loosen the injection head through fixed block 8 from this, in order to accomplish the injection.

From this, the injection mold of this embodiment directly uses fixed block 8 to press from both sides the injection head tightly, and stability when the raw materials of injection molding is injected in the increase, and can guarantee that the raw materials of injection molding fills up the mould inner wall completely to prevent the inside space that appears of injection molding, influence product quality, in addition after the injection is accomplished, fixed block 8 can directly loosen under the effect of liftout plate 9, makes things convenient for pulling out of injection head more.

Example 2:

the difference between this embodiment and embodiment 1 is only that the top of the fixing block 8 is a slope and is provided with a plurality of balls 11, so that the injection head of the injection machine can be conveniently inserted into the gate 3 through the slope at the top of the fixing block 8 and the balls 11.

In addition, the opposite face of fixed block 8 all is equipped with a plurality of and is used for fastening the tight piece 10 that presss from both sides of injection head to the mode injection head breaks away from with runner 3, stability when increasing the injection.

Furthermore, the surface of each clamping block 10 is provided with anti-skid grains to increase friction force and enhance clamping effect; and the inside fixedly connected with cushion 12 of runner 3 near fixed block 8 for protect fixed block 8 when fixed block 8 is close to runner 3 inner wall.

The opposite surfaces of the ejector plate 9 are inclined surfaces, so that an injection head can inject injection molding raw materials into the mold main body 1 conveniently; meanwhile, the ejector plate 9 is a silica gel plate which has elasticity and is convenient for ejecting the ejector plate 9, and the ejection cavity 13 is trapezoidal, so that the injection molding piece can be conveniently taken out from the ejection cavity 13 after the lamp holder injection molding piece is molded.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the principles of the present invention may be applied to any other embodiment without departing from the spirit and scope of the present invention.
