DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0017] Example: Figure 1-4As shown, the utility model provides a lighting lampshade molding device, including a base plate 1, an electric push rod 12 is fixedly installed in the middle of the top of the base plate 1, a placing table 2 is provided at the top of the electric push rod 12, the middle of the bottom end of the placing table 2 is fixedly installed on the driving end of the electric push rod 12, a fixed block 23 is fixedly installed at the top of the placing table 2, four lower mold slide blocks 21 are slidably provided at the top of the placing table 2, two symmetrically distributed limit blocks 211 are fixedly installed at the bottom ends of the four lower mold slide blocks 21, two symmetrically distributed springs 22 are fixedly installed at the lower parts of the four lower mold slide blocks 21, and the other ends of the multiple springs 22 are fixedly installed at the lower part of the fixed block 23, by arranging the springs 22, the reaction force of the springs 22 makes the four lower mold slide blocks 21 contact each other more closely, an upper mold cover 3 is provided at the top of the four lower mold slide blocks 21, the bottom end of the upper mold cover 3 is in contact with the top of the lower mold slide block 21, and four mirror-distributed second limit rods 32 are fixedly installed at the bottom end of the upper mold cover 3.

[0018] Two moving blocks 27 are provided on the opposite sides of the two lower mold slide blocks 21, and the two moving blocks 27 are slidably clamped in the lower part of the fixed block 23. The opposite ends of the two moving blocks 27 are fixedly installed on the lower part of the lower mold slide block 21. Two diagonally distributed sliding grooves 26 are opened in the middle of the opposite sides of the two moving blocks 27. A connecting rod 25 is slidably clamped in the middle of the two sliding grooves 26. A push handle 24 is fixedly installed on the top of the connecting rod 25. The upper part of the connecting rod 25 slides through the middle of the fixed block 23.

[0019] A glue injection hole 31 is provided in the middle of the upper mold cover 3 . By providing the glue injection hole 31 , the glue injection raw material can be injected into the molding groove 213 through the glue injection hole 31 .

[0020] The middle parts of the four lower mold slide blocks 21 are all provided with limiting holes 321, and the four second limiting rods 32 are all slidably clamped inside the limiting holes 321. By setting the limiting holes 321 and sliding the second limiting rods 32 inside the limiting holes 321, when the placing table 2 moves downward, the lower mold slide blocks 21 can be driven by the limiting of the second limiting rods 32 to spread to the surroundings, thereby away from the molded lighting lampshade.

[0021] A plurality of limit grooves 212 are provided on the upper part of the placing table 2, and a plurality of limit blocks 211 are slidably mounted inside the limit grooves 212. By setting the limit grooves 212 and by sliding the limit blocks 211 inside the limit grooves 212, the lower mold slider 21 is more stable when sliding on the top of the placing table 2.

[0022] Two symmetrically distributed mounting holes 111 are provided on both sides of the placement table 2. The mounting holes 111 are provided to install a device for limiting the upward and downward movement of the placement table 2, making it more stable.

[0023] The opposite sides of the four lower mold slide blocks 21 are all provided with molding grooves 213 , and the injection holes 31 are interconnected with the molding grooves 213 . By providing the molding grooves 213 , the raw materials for injection are cooled inside the molding grooves 213 to form the required lighting lampshades.

[0024] Four symmetrically distributed first limit rods 11 are fixedly installed on the top of the base plate 1. The four first limit rods 11 all slide through the mounting holes 111. The bottom end of the upper mold cover 3 is fixedly installed on the top of the first limit rod 11. By setting the first limit rod 11 and limiting the placement table 2 by the first limit rod 11, the stability of the placement table 2 is improved.

[0025] Working principle: In actual use, the electric push rod 12 drives the placement table 2 to move upward, so that the lower mold slide block 21 is in close contact with the bottom end of the upper mold cover 3, and the raw material is injected through the injection hole 31 to enter the interior of the molding groove 213. After molding, the electric push rod 12 drives the placement table 2 to move downward. When the placement table 2 moves downward, the second limiting rod 32 slides inside the limiting hole 321 of the lower mold slide block 21. When the placement table 2 moves downward, the second limiting rod 32 is limited, so that the four lower mold slide blocks 21 spread out to the surroundings, so that the four lower mold slide blocks 21 are away from the side wall of the lampshade formed by injection molding, so as to facilitate its removal;

[0026] When the lower mold slider 21 moves to both sides, it will drive the two moving blocks 27 to move to both sides respectively. Since the lower sliding part of the connecting rod 25 is slidingly clamped inside the slide groove 26, when the moving block 27 moves, it will drive the connecting rod 25 to move upward, so that the lampshade formed by injection molding can be lifted up through the push handle 24, making it convenient for the staff to remove the lampshade formed by injection molding.

[0027] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
