Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a high-efficiency injection mold for displays that is easy to demold. Background Technology

[0002] Injection molds are tools used in injection molding processes, primarily for manufacturing various plastic products. High-efficiency injection molds for displays refer to injection molds specifically designed for producing display-related components (such as display shells and frames), which can significantly improve production efficiency and reduce production costs while ensuring product quality.

[0003] During product manufacturing, sol particles enter the mold through the injection port. After cooling inside the mold, the sol particles can be transformed into the desired product shape. After the ejector pin pushes the product out, the worker will manually enter the mold to remove the product.

[0004] The existing technology has the following drawbacks: In some existing equipment, after the ejector pin pushes the product out, the operator needs to enter the mold with their hands to retrieve the product. If the operator makes a mistake or the equipment malfunctions, it may cause injury to the operator. The device has poor safety. Moreover, when changing the mold plate, multiple bolt tightening operations are required, which is cumbersome, time-consuming and labor-intensive. Therefore, a high-efficiency injection mold for displays that is easy to demold is proposed to solve the above problems. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figures 1-3This utility model provides an embodiment of a high-efficiency injection mold for displays that facilitates demolding. The mold includes a base 1, which supports the entire device. A worktable 2 is fixedly connected to the top of the base 1. The worktable 2 has an opening, preventing obstruction of the trapezoidal block 5 when the ejector pin 4 moves upward with it. A mold frame 6 is fixedly connected to the top of the worktable 2. An upper mold corresponding to a mold plate 7 is mounted on the worktable 2. The mold plate 7 is detachably mounted on the inner wall of the mold frame 6. A hydraulic rod 3 is provided on the upper surface of the base 1. The hydraulic rod 3 is a mechanical device that uses hydraulic principles to achieve functions such as support, buffering, braking, height adjustment, and angle adjustment. Ejector pins 4 are fixedly connected to the top of the hydraulic rod 3. Multiple sets of ejector pins 4 are provided. Ejector pins 4 are parts in the mold used to eject the molded product. The above is the current... The technology is technically sound and will not be elaborated upon further. A trapezoidal block 5 is fixedly connected to the upper outer wall of the ejector pin 4. A telescopic rod 8 is installed at the top of the worktable 2 via a bracket. The electric telescopic rod 8 is driven by a motor to convert the rotational motion of the motor into the linear extension and retraction motion of the rod. A push plate 9 is fixedly connected to the movable end of the telescopic rod 8. The push plate 9 is L-shaped and can push the product out from above the mold plate 7. A movable mechanism is provided on the inner wall of the worktable 2. A disassembly assembly is provided on the inner wall of the mold frame 6. The movable mechanism includes a moving plate 10. A rectangular block 12 is elastically connected to the right side wall of the moving plate 10 via a movable spring 11. The moving plate 10 passes through and slides on the inner wall of the worktable 2. Two sets of moving plates 10 are provided. The worktable 2 has slots corresponding to the moving plates 10 to facilitate the left and right movement of the moving plates 10.

[0036] Reference Figures 4-6 The disassembly assembly includes a stop block 13. A plug block 15 is elastically connected to the inner wall of the left end of the stop block 13 via a movable spring 14. The stop block 13 passes through and is slidably connected to the inner wall of the mold frame 6. The mold frame 6 has a slot corresponding to the stop block 13 to facilitate its back-and-forth movement. The inner wall of the left end of the stop block 13 is fixedly connected to one end of the movable spring 14, and the other end of the movable spring 14 is fixedly connected to the left side wall of the plug block 15. When the plug block 15 moves to the left, the movable spring 14 is compressed. During reset, the spring force of the movable spring 14 is used to reset the insert 15. The insert 15 is slidably connected to the inner wall of the stop block 13. The stop block 13 has a slot corresponding to the insert 15 to facilitate the left and right movement of the insert 15. The insert 15 is inserted into the top of the mold frame 6. The mold frame 6 has a slot corresponding to the insert 15. In the initial state, the insert 15 is inserted into the first slot. The bottom end of the stop block 13 is in contact with the top end of the mold plate 7. The stop block 13 forms a blocking and limiting effect on the mold plate 7.

[0037] Reference Figure 2 , Figure 3 and Figure 7Ejector pin 4 is slidably connected to the inner wall of mold frame 6. Mold frame 6 has a slot corresponding to ejector pin 4, allowing ejector pin 4 to move vertically. Ejector pin 4 is inserted into the inner wall of mold plate 7, which also has a slot corresponding to ejector pin 4 for vertical movement. The right sidewall of movable plate 10 is fixedly connected to one end of movable spring 11, and the other end of movable spring 11 is fixedly connected to the left sidewall of rectangular block 12. When movable plate 10 moves to the right, movable spring 11 is... During compression and reset, the elastic force of the movable spring 11 is used to reset the moving plate 10. The rectangular block 12 is fixedly connected to the top of the worktable 2. The push plate 9 is slidably connected to the top of the moving plate 10. The moving plate 10 has a slot corresponding to the push plate 9 to facilitate the left and right movement of the push plate 9. The right side wall of the trapezoidal block 5 contacts the left end of the moving plate 10. The trapezoidal block 5 contacts and squeezes the moving plate 10, causing the moving plate 10 to move to the right. The inner side wall of the moving plate 10 contacts the top of the mold frame 6.

[0038] Working principle: When the product is finished, the externally controlled hydraulic rod 3 moves the ejector pin 4 and trapezoidal block 5 upward. As the trapezoidal block 5 stops pressing the moving plate 10, it moves the moving plate 10 to the left under the elastic force of the movable spring 11. At this time, the ejector pin 4 pushes the product out, and the upper surface of the moving plate 10 contacts the bottom of the product and supports it. Then, the externally controlled telescopic rod 8 moves the push plate 9 to the left, pushing the product to the left for easy picking up by the staff. After the staff has picked up the product, the hydraulic rod 3 moves the ejector pin 4 and trapezoidal block 5 downward. The trapezoidal block 5 presses the moving plate 10, causing the moving plate 10 to move to the right and press the movable spring 11. The movable spring 11 is in a compressed state. When the product is finished again, the ejector pin 4 repeats the above trajectory movement.

[0039] When it is necessary to replace the mold plate 7, the operator can move the insert block 15 to the left. The insert block 15 will compress the moving spring 14. When the insert block 15 separates from the first set of slots on the mold frame 6, the operator moves the insert block 15 backward. The insert block 15 will move the stop block 13 backward. When the stop block 13 no longer blocks the mold plate 7, the insert block 15 coincides with the second slot on the mold frame 6. The operator releases the insert block 15 and uses the elasticity of the moving spring 14 to insert the insert block 15 into the slot of the mold frame 6, thus limiting the stop block 13. Then, the operator can align the new mold plate 7 and insert it into the slot of the mold frame 6. The operator presses the insert block 15 and moves the stop block 13 forward. When the stop block 13 blocks and limits the mold plate 7, the operator releases the insert block 15 and lets it insert into the slot, thus limiting the blocking of the mold plate 7. If it is necessary to replace the mold plate 7 again, simply repeat the above steps.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
