Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold for a liquid crystal television base. Background Art

[0002] The LCD TV base is a crucial component supporting the TV, providing a secure support and ensuring stability and safety during use. The base is a built-in or attachable support frame for the TV, used to secure the TV in a stable position to prevent it from tipping over or becoming damaged. Existing LCD TV bases require injection molding, a tool that injects molten plastic material into a mold and forms the desired product shape through pressurization and cooling. The principle is to use high pressure to inject molten plastic into the mold cavity, solidify it after cooling, and finally remove the finished product from the mold. However, existing injection molds for LCD TV bases require a secondary ejection process after mold opening to release the molded material. This prevents the upper mold from moving in conjunction with the ejector pins to release the product, making demolding more complex. Utility Model Content

[0003] The purpose of the utility model is to provide an injection mold for an LCD TV base, so as to solve the problem in the prior art that, in order to demold the LCD TV base after molding, the existing injection mold for the LCD TV base needs to perform a secondary ejection of the molded material after the mold is opened. After the mold is opened, the movement of the upper mold can no longer be linked to the ejector pin for demolding, making demolding more troublesome.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The top of the sliding top plate 21 is symmetrically fixed with an ejector rod 13, which is slidably connected to the support base 1 and the lower mold body 2, and the top of the ejector rod 13 is fixedly connected to the ejector plate 3.

[0027] It can be understood that the present invention performs injection molding on the LCD TV base through the upper mold body 10 and the lower mold body 2. After the injection molding work is completed, the output end of the hydraulic cylinder 8 drives the movable slide 9 and the upper mold body 10 to move upward, and the upper mold body 10 and the lower mold body 2 are opened. When the movable slide 9 moves upward, it drives the connecting side blocks 20 on both sides to move synchronously. The connecting side blocks 20 drive the limiting slider 18 sliding inside the limiting slide 17 to move. When the limiting slider 18 is pushed to the uppermost position of the limiting slide 17, the output end of the hydraulic cylinder 8 drives the movable slide 9 and the upper mold body 10 to continue to move upward. The movable slide 9 drives the limiting slider 18 to move upward through the connecting side blocks 20, and the limiting slider 18 drives the pulling plate 16 through the limiting slide 17. When the pull plate 16 moves upward, it drives the sliding top plate 21 at the bottom to move upward. The sliding top plate 21 slides on the outside of the second limit rod 14. The sliding top plate 21 drives the ejector rod 13 to move upward. When the ejector rod 13 moves upward, it drives the ejection plate 3 to move upward. The ejection plate 3 drives the ejector pin 4 to move upward, and the molded LCD TV base in the lower mold body 2 is ejected by the ejector pin 4. When the ejection plate 3 moves upward, the spring 6 on the outside of the fixed rod 5 is pressed. After the molding material is taken out, the output end of the hydraulic cylinder 8 moves downward. At this time, the spring 6 will reset and drive the ejection plate 3 and the ejector pin 4 to move downward. The ejection plate 3 drives the ejector rod 13, the sliding top plate 21 and the pulling plate 16 to move downward and reset, thereby ensuring the next injection molding of the upper mold body 10 and the lower mold body 2.

[0028] See also Figures 1 to 3 , support frame 7, support frame 7 is fixed to the top of the support base 1, a hydraulic cylinder 8 is installed on the top of the support frame 7, the output end of the hydraulic cylinder 8 is fixed to the movable slide 9, the internal symmetrical sliding connection of the support frame 7 is connected to the limiting slide 15, the bottom end of the limiting slide 15 is fixed to the movable slide 9, and the pulling plate 16 is slidably connected to the support frame 7.

[0029] It can be understood that, in the present invention, the output end of the hydraulic cylinder 8 drives the movable slide 9 and the upper mold body 10 to move, thereby performing mold opening and mold closing operations.

[0030] See also Figures 1 to 3 A plurality of fixing rods 5 are symmetrically and slidably provided inside the ejection plate 3 , the fixing rods 5 are fixedly connected to the lower mold body 2 , and a spring 6 is sleeved on the outer side of the fixing rods 5 .

[0031] It is understandable that, in the present invention, when the ejection plate 3 moves upward, the ejection plate 3 and the internal fixed rod 5 slide in a limited manner, and the ejection plate 3 moving upward is reset by the spring 6 .

[0032] See also Figure 4One side of the connecting side block 20 is slidably connected to the pulling plate 16, and a limiting slide groove 17 is provided on the inner side of the pulling plate 16. A limiting slider 18 is provided for sliding inside the limiting slide groove 17. One side of the limiting slider 18 is fixedly connected to the connecting side block 20, and a No. 3 limiting rod 19 is provided for sliding inside the limiting slider 18. The No. 3 limiting rod 19 is fixedly connected to the limiting slide groove 17.

[0033] When the upper mold body 10 is pushed up to the uppermost position of the limit slide 17, the output end of the hydraulic cylinder 8 drives the moving slide 9 and the upper mold body 10 to continue to move upward, and the moving slide 9 drives the limit slide 18 to move upward through the connecting side blocks 20. The limit slide 18 drives the pulling plate 16 to move upward through the limit slide 17. When the pulling plate 16 moves upward, it drives the sliding top plate 21 at the bottom to move upward, and the sliding top plate 21 drives the ejector rod 13 to move upward. When the ejector rod 13 moves upward, it drives the ejection plate 3 to move upward, and the ejection plate 3 drives the ejector pin 4 to move upward, and the molded LCD TV base in the lower mold body 2 is ejected by the ejector pin 4. When the mold is opened, the molded material in the lower mold body 2 can be ejected, which is convenient for removal after molding.

[0034] See also Figure 3 A plurality of second limiting rods 14 are symmetrically and slidingly provided inside the sliding top plate 21 , and the second limiting rods 14 are fixedly connected to the support base 1 .

[0035] It is understandable that, in the present invention, when the height position of the sliding top plate 21 is adjusted, the adjustment position is limited by the second limiting rod 14 in the sliding top plate 21 , thereby improving stability.
