Description

Technical Field

[0001] This utility model relates to the field of lampshade mold technology, specifically to an injection mold for a lampshade. Background Technology

[0002] Lampshade molds are specialized tools used to make lampshades. They have precise dimensions and specific shapes, and can mold various materials, such as plastic and glass, into a pre-designed pattern, ensuring that the produced lampshades are of uniform specifications and have a neat appearance. With the help of lampshade molds, lampshades of different styles and designs can be manufactured efficiently and in batches to meet the diverse needs of lighting products and improve production efficiency and product quality.

[0003] However, with traditional lampshade injection molds, after injection molding is completed, operators need to manually remove the finished lampshade from the mold. Since the finished product is hot, and the reserved edge on the outside of the finished lampshade for easy handling has many burrs, it is easy to burn the operator and cut their hands. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide an injection mold for lampshades, which can conveniently clamp and remove the finished lampshade, thereby reducing the damage to the operator's hands caused by the finished lampshade and reducing the risk of puncture wounds to the operator's hands from the pre-reserved edge of the finished lampshade.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an injection mold for a lampshade, comprising a stable base and a support frame. Four sets of first support rods are fixed to one side of the top of the stable base, and four sets of second support rods are fixed to the other side of the top of the stable base. A second top plate is provided on the top of the four sets of second support rods, and a support frame is fixed to the bottom of the second top plate. The support frame has a groove-shaped structure inside for two sets of sliders to slide, and a movable seat is fixed to the top of the two sets of sliders. An electric telescopic rod is provided on the top of the movable seat, and a sliding seat is provided at the output end of the electric telescopic rod. Both sides of the sliding seat are engaged and slide with the movable seat. A first clamping rod and a second clamping rod are rotatably mounted on the inner bottom of the sliding seat via a rotating shaft.

[0006] By adopting the above technical solution, the second support rod is used to provide stable support for the second top plate and its bottom support frame. The two sets of sliders drive the movable seat to slide through the two sets of groove-shaped mechanisms inside the support frame. The electric telescopic rod drives the sliding seat to move up and down in the movable seat. The first clamping rod and the second clamping rod are used to remove the completed lampshade body from the lower mold.

[0007] Furthermore, the top of the first support rods of the four sets is fixed to the first top plate, and the top of the first top plate is provided with a cylinder.

[0008] By adopting the above technical solution, firstly, the top of the first plate is fixed at the top of the four sets of first support rods, which further enhances the stability of the entire mold structure. A cylinder is set at the top of the first plate, which can drive the upper mold to accurately perform mold closing and opening actions.

[0009] Furthermore, an upper mold is installed at the output end of the cylinder, and the outer side of the upper mold is slidably limited by four sets of first support rods.

[0010] By adopting the above technical solution, the upper mold is installed at the cylinder output end to provide direct and precise drive to the upper mold. The outer side of the upper mold slides and limits with the four sets of first support rods, ensuring the stability of the upper mold during the up and down movement.

[0011] Furthermore, a lower mold is fixed to the top of the stabilizing base and directly below the upper mold, and a lampshade body is provided inside the lower mold.

[0012] By adopting the above technical solution, the bottom of the stable base is fixed directly below the upper mold, ensuring accurate alignment when the upper and lower molds are closed.

[0013] Furthermore, a lampshade edge is fixed to the top of the lampshade body, and a number of lampshade lifting rods are provided on the top of the lampshade edge.

[0014] By adopting the above technical solution, the lampshade can be easily removed from the lower mold without touching the lampshade body by using the lampshade removal rod on the rough edge of the lampshade on the top of the lampshade body.

[0015] Furthermore, the first clamping rod and the second clamping rod have several sets of groove-shaped structures at the ends near the lower mold, which correspond to and fit into several sets of lampshade picking rods.

[0016] By adopting the above technical solution, several sets of groove-like structures are opened at the end of the first and second clamping rods near the lower mold. This design enables the clamping rods to accurately align with the lampshade picking rod, improving the accuracy of the gripping.

[0017] In summary, the present invention has the following main advantages:

[0018] This invention utilizes a support frame, a movable seat, a slider, and a sliding base. When an operator holds the handles at the rear ends of the first and second clamping rods, the movable seat moves within the support frame via the bottom slider. The slots at the front ends of the first and second clamping rods then clamp the lampshade lifting rod located in the middle of the lampshade's rough edge at the top of the lampshade body. The control center then activates an electric telescopic rod, causing the sliding base to lift the first and second clamping rods within the movable base, thereby removing the lampshade body from the lower mold. This design reduces the risk of burns to the operator's hands from the lampshade's rough edge and the lampshade lifting rod, as well as injuries from the surface barbs. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] An injection mold for a lampshade, such as Figures 1-4As shown, it includes a stable base 1 and a support frame 12. Four sets of first support rods 2 are fixed on one side of the top of the stable base 1, and four sets of second support rods 10 are fixed on the other side of the top of the stable base 1. A second top plate 11 is provided on the top of the four sets of second support rods 10, and a support frame 12 is fixed on the bottom of the second top plate 11. The support frame 12 has a groove structure inside for two sets of sliders 14 to slide. A movable seat 13 is fixed on the top of the two sets of sliders 14. An electric telescopic rod 15 is provided on the top of the movable seat 13, and a sliding seat 16 is provided at the output end of the electric telescopic rod 15. Both sides of the sliding seat 16 are engaged and slide with the movable seat 13. A first clamping rod 17 and a second clamping rod 18 are rotatably mounted on the inner bottom of the sliding seat 16 via a rotating shaft.

[0026] The support frame 12 has a groove structure inside for the slider 14 to slide. The movable seat 13 can move flexibly and adjust its position to accurately clamp the lamp cover. The electric telescopic rod 15, together with the sliding seat 16, can drive the first clamping rod 17 and the second clamping rod 18 to rise and fall, realize the automatic removal of the lamp cover, improve production efficiency and reduce the risk of manual operation.

[0027] See Figure 1 and Figure 2 The top of the four sets of first support rods 2 is fixed to the first top plate 3, and the top of the first top plate 3 is provided with a cylinder 4.

[0028] The first support rods 2 are fixed to the top of the first top plate 3, providing a stable mounting platform for the cylinder 4 and ensuring the stability of the cylinder 4 during operation. The cylinder 4 is set on the top of the first top plate 3, which makes the injection molding process more automated and efficient, improves the production efficiency of the lampshade body 7, and ensures uniform mold closing force, which helps to improve the molding quality of the lampshade body 7.

[0029] See Figure 1 and Figure 2 The output end of cylinder 4 is equipped with an upper mold 5, and the outer side of the upper mold 5 is slidably limited by the four sets of first support rods 2.

[0030] Among them, cylinder 4 is used to accurately control the closing and opening of the upper mold 5, which improves the efficiency and accuracy of injection molding operation. The outer side of the upper mold 5 is slidably limited by four sets of first support rods 2 to prevent it from shifting or shaking, ensuring the shape accuracy and dimensional consistency of the lampshade body 7 during the injection molding process, thus improving product quality.

[0031] See Figure 1 , Figure 2 and Figure 3 A lower mold 6 is fixed on the top of the stable base 1 and directly below the upper mold 5, and a lampshade body 7 is provided inside the lower mold 6.

[0032] The stable base 1, located at the top and directly below the upper mold 5, fixes the lower mold 6, providing a stable and accurate molding space for the injection molding of the lampshade body 7, which helps to improve the molding quality of the lampshade.

[0033] See Figure 1 , Figure 2 and Figure 3 The top of the lampshade body 7 is fixed with a lampshade rough edge 8, and the top of the lampshade rough edge 8 is provided with several sets of lampshade lifting rods 9.

[0034] Among them, several sets of lampshade picking rods 9 are set on the top of the lampshade rough edge 8, which provides convenience for subsequent picking operations. Operators or picking devices can take the lampshade body 7 out of the mold by clamping the lampshade picking rods 9, avoiding the risk of burns caused by direct contact with the lampshade body 7 and the risk of being scratched by the barbs of the lampshade rough edge 8, thus improving the safety and convenience of production operations.

[0035] See Figure 1 , Figure 3 and Figure 4 The first clamping rod 17 and the second clamping rod 18 have several sets of groove-shaped structures at the ends near the lower mold 6, which correspond to and fit into several sets of lampshade picking rods 9.

[0036] The groove structure corresponds to and is matched with several sets of lampshade picking rods 9, ensuring the stability of the connection between the clamping rod and the lampshade picking rod 9. During the process of taking out the lampshade body 7 by driving the sliding seat 16 to rise through the electric telescopic rod 15, the lampshade body 7 can be prevented from slipping, ensuring the smooth progress of the picking operation and improving the stability and reliability of the entire production process.

[0037] The implementation principle of this embodiment is as follows: First, the stable base 1 is placed stably in the designated position. Then, the cylinder 4 is activated through the control center to allow the upper mold 5 and the lower mold 6 to close and perform injection molding. After the lower mold 6 is completed, the operator can move the movable seat 13 inside the support frame 12 by holding the handles at the rear ends of the first clamping rod 17 and the second clamping rod 18. Then, the slots at the front ends of the first clamping rod 17 and the second clamping rod 18 are used to clamp the lampshade lifting rod 9 in the middle of the lampshade rough edge 8 on the top of the lampshade body 7. Finally, the control center... Activate the electric telescopic rod 15 to allow the sliding seat 16 to drive the first clamping rod 17 and the second clamping rod 18 to rise inside the moving seat 13, thereby removing the lampshade body 7 from inside the lower mold 6. This reduces the risk of burns to the operator's hands from the lampshade burrs 8 on the top of the lampshade body 7 and the lampshade lifting rod 9, as well as the injury to the operator's hands from the barbs on its surface. Finally, by pulling the first clamping rod 17 and the second clamping rod 18, the moving seat 13 is slid inside the support frame 12 via the slider 14, and the lampshade body 7 is removed from the area between the upper mold 5 and the lower mold 6.
