Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Figure 1 The mold injection molding device of a downlight shown comprises a base 1 , two brackets 101 are symmetrically fixed on both sides of the lower end surface of the base 1 , and the bottom of the bracket 101 extends horizontally and is provided with a plurality of fixing holes 102 .

[0024] An injection molding lower mold cylinder 2 is fixed to the middle of the upper end surface of the base 1, and a top seat 5 is provided above the base 1, and an injection molding upper mold column 6 is fixed to the middle of the lower end surface of the top seat 5. The diameter of the injection molding upper mold column 6 is smaller than the inner diameter of the injection molding lower mold cylinder 2, so that a gap is left after the injection molding upper mold column 6 and the injection molding lower mold cylinder 2 are connected. Therefore, the injection molding upper mold column 6 and the injection molding lower mold cylinder 2 are connected to form a mold cavity for injection molding of the downlight shell, and the gap between the injection molding upper mold column 6 and the injection molding lower mold cylinder 2 is the thickness of the downlight shell after injection molding.

[0025] Among them, in this embodiment, with Figure 2 and Figure 3 As shown, the bottom of the lower injection mold barrel 2 is equipped with an adjusting member 8, and the adjusting member 8 includes a fixed plate 802, and the fixed plate 802 is slidably installed on the bottom of the lower injection mold barrel 2, and the upper end surface of the fixed plate 802 is fixed with a downlight top mold 804 for forming the top of the downlight. Specifically, the lower end surface of the fixed plate 802 is fixed with a vertical screw 801, and the lower end thread of the screw 801 passes through the lower end surface of the base 1 and is located between the two brackets 101, so that the fixed plate 802 can be controlled to move up and down at the bottom of the lower injection mold barrel 2 by rotating the screw 801.

[0026] An embedding groove is provided around the edge of the upper end surface of the fixing plate 802, in which a sealing rubber ring 803 is fixed, and a screw hole is provided in the middle of the upper end surface of the fixing plate 802. A stud with a thread inserted into the screw hole in the middle of the fixing plate 802 is fixed on the lower end surface of the downlight top mold 804, so that the downlight top mold 804 can be detachably fixed on the fixing plate 802 for easy replacement.

[0027] Cooperate Figure 4 As shown, a fixable support plate 4 is sleeved on the injection lower mold cylinder 2, and support rods 7 for abutting against the upper end surface of the support plate 4 are symmetrically fixed on both sides of the lower end surface of the top seat 5, so that the support plate 4 can support the top seat 5 through the support rods 7 to adjust the depth of the injection upper mold column 6 driven by the top seat 5 to extend into the injection lower mold cylinder 2.

[0028] Specifically, a plurality of guide pillars 3 are fixed around the upper end surface of the base 1, and sliding holes 402 for the guide pillars 3 to pass through are correspondingly opened around the support plate 4, and guide holes 501 for the guide pillars 3 to pass through are correspondingly opened around the top seat 5, so that the support plate 4 can stably slide up and down on the injection lower mold cylinder 2.

The fastening bolts 404 abut against the outer edge surface of the injection molding lower mold barrel 2, so that the position of the support plate 4 can be fixed by abutting the fastening bolts 404. In specific implementation, the side of the injection molding lower mold barrel 2 can be frosted to increase the friction force, or a row of vertically arranged slots can be set on the side of the injection molding lower mold barrel 2 to be plugged in with the end of the fastening bolts 404 to ensure the fixing effect of the fastening bolts 404 on the support plate 4.

[0030] Working principle of the utility model: when the model injection molding device of the downlight is in use, the height of the sealing rubber ring 803 at the bottom of the injection lower mold barrel 2 can be adjusted by rotating the screw 801, that is, the height of the downlight top mold 804 at the bottom of the injection lower mold barrel 2 can be adjusted to adjust the depth in the injection lower mold barrel 2. At the same time, by sliding the support plate 4 along the outer edge surface of the injection lower mold barrel 2, and then screwing the fastening bolts 404 to abut the outer edge surface of the injection lower mold barrel 2 for fixation, the support plate 4 can support the top seat 5 at different heights above the injection lower mold barrel 2 through the support rod 7, and even the depth of the injection upper mold column 6 and even the injection lower mold barrel 2 can be adjusted, so that the injection lower mold barrel 2 with internal depth adjustment and the injection upper mold column 6 with adjustable insertion depth can cooperate to form downlight mold cavities of various specifications, which is not only conducive to the rapid production of downlight shells of various specifications, but also flexible and convenient to use.
