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 3, the double discharge injection mold in this embodiment includes: go up mould 1, the bottom of going up mould 1 is equipped with lower mould 2, it is concrete, go up swing joint between mould 1 and the lower mould 2, go up and be equipped with core 10 between mould 1 and the lower mould 2, it is concrete, the both ends of core 10 are respectively in

last mould

1 and 2 fixed connection of lower mould, the both sides of core 10 all are equipped with and press from both sides tight piece 8, it is concrete, press from both sides tight piece 8 and can dismantle with core 10 and be connected, two press from both sides tight piece 8 all with last mould 1 sliding connection, two back of the body that press from both sides tight piece 8 all are equipped with die clamping cylinder 5, every die clamping cylinder 5 all with last mould 1 fixed connection, the inside of lower mould 2 is equipped with ejecting spring 4, ejecting spring 4's top is equipped with ejecting piece 6.

In this embodiment, the opposite surfaces of the two ejection blocks 6 are provided with chamfers so as to facilitate sliding between the two ejection blocks and the clamping block 8, and meanwhile, the opposite surfaces of the ejection blocks 6 are planes so as to increase the stability of sliding of the ejection blocks 6 through the horizontal plane. The surface of pressing from both sides tight piece 8 is carved with anti-skidding line to anti-skidding line prevents that core 10 from breaking away from pressing from both sides tight piece 8, and the tight stability of the tight piece 8 clamp of increase, and further, the opposite face of two tight pieces 8 of clamp all is equipped with the chamfer, and it is fixed firm with core 10 to press from both sides tight piece 8 more conveniently.

The scheme has the following working processes:

when an injection molding part of a mounting hole in a lamp holder is machined, plastic is injected into a mold, after the mold is cooled, after the injection molding part is molded, the clamping cylinder 5 is started, the clamping cylinder 5 drives the clamping block 8 to be drawn back, the clamping block 8 loosens the mold core 10, when the clamping block 8 is separated from the ejection block 6, the ejection spring 4 at the bottom of the ejection block 6 rebounds, the mold core 10 is ejected out by the ejection spring 4, the injection molding part in the mold core 10 is taken out, and the whole mold is unloaded.

According to the working process, the following steps are known:

when an injection molding part of a mounting hole in a lamp holder is machined, plastic is injected into a mold, after the mold is cooled, after the injection molding part is molded, the clamping cylinder 5 is started, the clamping cylinder 5 drives the clamping block 8 to be drawn back, the clamping block 8 loosens the mold core 10, when the clamping block 8 is separated from the ejection block 6, the ejection spring 4 at the bottom of the ejection block 6 rebounds, the mold core 10 is ejected out by the ejection spring 4, the injection molding part in the mold core 10 is taken out, and the whole mold is unloaded. The prior art adds man-hour to lamp stand mounting hole injection molding, injects the plastic inside the mould, uses the last mould 1 and the lower mould 2 of mould to press from both sides tightly, and when the mould was moulded plastics, stability was relatively poor, and led to the injection molding to appear processing badly easily, influenced the processing of injection molding, direct discharge when unloading moreover, it is not convenient enough to unload. This scheme uses two die clamping cylinder 5 to press from both sides tight mould core 10, guarantees the stability that the mould adds man-hour, and when die clamping cylinder 5 withdraws back, ejecting piece 6 is directly ejecting by ejecting spring 4, makes things convenient for unloading of core 10 more.

Further, the side of going up mould 1 all is equipped with the blotter 9 that thickness is 1cm, and every blotter 9 all with go up mould 1 fixed connection to this slows down the impact force between clamp splice 8 and the last mould 1 through blotter 9, and the protection is gone up mould 1.

Example 2:

the embodiment is different from the embodiment 1 only in that a gap is arranged between the output end of the clamping cylinder 5 and the upper die 1 in the embodiment, so that the cylinder is prevented from rubbing against the upper die 1, and the cylinder and the upper die 1 are protected; guide post 3 wears to be equipped with in the inside of ejecting spring 4, and guide post 3 and lower mould 2 fixed connection, accessible guide post 3 leads ejecting spring 4 from this, makes things convenient for ejecting of ejecting spring 4, and the surface cover of ejecting piece 6 is equipped with sealing ring 7 simultaneously, and sealing

ring

7 and 2 interference fit of lower mould for lower mould 2 is sealed firm with ejecting piece 6.

To sum up, the utility model discloses a mould adds man-hour in the mounting hole injection molding to the lamp stand, pour into the plastic into the mould, the area mould cools off the back, after the injection molding shaping, start die clamping cylinder, die clamping cylinder drives and presss from both sides tight piece and withdraws, press from both sides tight piece and loosen the core, when pressing from both sides tight piece and break away from ejecting piece, the ejecting spring of ejecting piece bottom kick-backs, ejecting spring is ejecting with the core, the injection molding in the core takes out, whole mould is unloaded and is accomplished, and simultaneously, this scheme uses two die clamping cylinder to press from both sides tight mould core, guarantee the stability that the mould adds man-hour, and when die clamping cylinder withdraws, ejecting piece is directly ejecting by ejecting spring, make things convenient for the unloading of.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
