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.

[0021] See also Figure 1-3 The utility model provides a technical solution: a feeding device for injection molding of a lamp bracket, comprising a feeding component 1 and a shaping component 2, the feeding component 1 and the shaping component 2 are used in conjunction with each other, the feeding component 1 comprises a first square base 101, a hollow cylindrical sleeve 102 is fixed on the first square base 101, the upper end of the sleeve 102 is an open structure, a hollow cylindrical heat-conducting barrel 103 is installed inside the sleeve 102, the upper end of the heat-conducting barrel 103 is an open structure, the sleeve 102 and the heat-conducting barrel 103 are connected to each other, and the heat-conducting barrel 103 is connected to the sleeve 102. A heating ring 104 is installed between the hot barrel 103. The heating ring 104 is a hollow structure, and the inner wall of the heating ring 104 fits the outer wall of the heat-conducting barrel 103, so as to improve the heating efficiency. A barrel cover 105 rotatably connected by a hinge shaft 106 is provided above the sleeve 102. The diameter of the barrel cover 105 is equal to the outer diameter of the sleeve 102, so as to facilitate the barrel cover 105 to be properly clamped on the opening of the sleeve 102. The sleeve 102 is a heat-insulating sleeve to prevent the sleeve 102 from overheating and causing burns to the operator;

[0022] By adding the design of the heat-conducting barrel 103 and the heating ring 104, the sleeve 102 and the heat-conducting barrel 103 cooperate to form a double-layer structure. The heating ring 104 is arranged between the sleeve 102 and the heat-conducting barrel 103, so that the temperature of the material can be maintained within the set temperature at all times, making it less likely that the injection molding process will not result in an unsatisfactory injection molding effect due to the drop in the temperature of the material in the heat-conducting barrel 103.

[0023] The barrel cover 105 is an insulated barrel cover to prevent the barrel cover 105 from overheating and causing burns to the operator. A lock buckle 110 is installed on the outer wall of the barrel cover 105 on the side away from the hinge shaft 106. One end of the lock buckle 110 is used in conjunction with a groove opened at the upper end of the outer wall of the sleeve 102, so that the barrel cover 105 can be pushed open due to the reaction force when the first electric push rod 107 is working.

[0024] A first electric push rod 107 is installed on the upper surface of the barrel cover 105, and the base of the first electric push rod 107 is fixed on the barrel cover 105. The output shaft of the first electric push rod 107 passes through the barrel cover 105 and is connected to a circular push plate 109. The diameter of the circular push plate 109 is equal to the inner diameter of the heat-conducting barrel 103.

When loading materials, the circular push plate 109 presses down the material in the heat-conducting barrel 103, forcing the material to flow out of the discharge port 112 through the feed pipe 111. A second electric push rod 113 is installed on the lower surface of the first square base 101, and a circular chassis 108 is installed on the output end of the second electric push rod 113, which is convenient for adjusting the height of the sleeve 102 and facilitating the staff to put the material into the heat-conducting barrel 103.

[0026] The shaping component 2 includes a second square base 201, on which a fixing module 203 is installed, and above the fixing module 203 a pressing module 204 is arranged. The fixing module 203 and the pressing module 204 are used together. During injection molding, the pressing module 204 is used to press down and fit the fixing module 203, and a lamp bracket is formed by injecting molding into the space reserved between the two.

[0027] A column 202 is also installed on the second square base 201, and a first connecting block 205 is fixed to the lower end of the outer wall of the column 202. One end of the first connecting block 205 is fixed to the outer wall of the fixed module 203, which is convenient for fixing the column 202 and the fixed module 203 together to prevent the movement between the two from causing unsatisfactory injection molding effect.

[0028] A slide groove 206 is provided on the column 202, and a slider 207 is installed in the slide groove 206. A third electric push rod 209 is installed on the top of the column 202. The output end of the third electric push rod 209 passes through the top of the column 202 and is connected to the slider 207. A second connecting block 208 is fixed on the slider 207. One end of the second connecting block 208 is fixed to the outer wall of the pressing module 204, so that the pressing module 204 can be controlled to move up and down, which is convenient for injection molding and removing the finished parts.
