Description

Technical Field

[0001] The utility model relates to the technical field of mold improvement mechanisms, and particularly relates to a mold improvement mechanism for improving product quality and reducing waste. Background Art

[0002] The mold improvement mechanism is designed to improve product quality and reduce waste. In injection molding production, there are many products that require the gate feeding form of a three-plate mold. Especially for small products with large production volumes and high appearance requirements, using a three-plate mold structure will generate gate waste several times the weight of the product, resulting in a great waste of costs. For general products, a conventional hot runner system can achieve gate-free, but there are also many cases where a full hot runner system cannot be realized due to the shape and appearance quality requirements of the product itself. Considering the above factors, a system improvement form that combines the three-plate mold gate and the hot runner system is now introduced to achieve a mold structure form that can both reduce waste and ensure quality.

[0003] The use operation of the traditional three-plate mold improvement mechanism in the gate feeding form includes: First, install and align the mold on the injection molding machine to ensure its firmness. Second, check and adjust the gate feeding system to ensure the smoothness of the gate and the runner, and optimize the gate size and position to reduce pressure loss. Then, set and adjust the mold temperature control system to ensure uniform temperature distribution and avoid quality problems caused by temperature differences. Finally, conduct trial mold adjustment, and through multiple injection molding tests, optimize the injection parameters to ensure that the product quality and production efficiency meet the expected standards.

[0004] The traditional three-plate mold can meet the forming requirements of most products, but for three-plate molds with large production volumes and many pickups, the proportion of gate waste is very large, which not only wastes raw materials but also increases the forming processing cost. Due to the special nature of the product structure, when a full hot runner forming system cannot be used, the resin material waste is saved by developing and improving the feeding system of the mold, and only the gate part of the product is retained, thus saving the waste of resin materials without affecting the appearance and quality of the product. Summary of the Utility Model

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Referring to Figure 1 - Figure 3 , an embodiment provided by the present invention: a mold improvement mechanism for improving production quality and reducing waste, including a base plate 1.

The outer wall of the pipe 10 is fixedly connected inside the hot runner system 5. Both ends of the pipe 10 are fixedly connected with a nozzle 9. The outer wall of the nozzle 9 is fixedly connected inside the nozzle protection block 6;

[0024] Specifically, first, on the basis of a conventional three-plate mold, a hot runner manifold 2 is introduced and firmly connected to the base plate 1. In this way, the hot runner system 5 becomes an integral part of the three-plate mold fixing plate. In order to minimize waste as much as possible, the nozzle protection block 6 is designed to be convex, closely attached to the back of the fixed side core 8, and at the same time connected and fixed to the stripper plate 3. The nozzle 9 in the hot runner system 5 is embedded therein. During the mold opening process, the nozzle 9 will slide with a small distance from the side wall of the nozzle protection block 6 during the mold opening action, so as to disconnect from the waste. Finally, the waste is taken out by a manipulator, optimizing the traditional gate 7 waste problem. The main gate waste of the gate 7 before improvement is eliminated after improvement, making the state of the gate 7 more streamlined and achieving the effect of reducing waste.

[0025] Referring to Figure 1 and Figure 3The outer wall of the seat plate 1 is fixedly connected with a slide bar 16, the outer wall of the hot runner manifold plate 2 is slidably connected with four slide bars 2 17, the outer wall of the discharge plate 3 is fixedly connected with a slide bar 3 18, the outer wall of the slide bar 16 is slidably connected with a limit plate 19, wherein the outer walls of two slide bars 2 17 are slidably connected to the inside of the limit plate 19, and the outer walls of the other two slide bars 2 17 are slidably connected to the limit plate 2 20, the inside of the limit plate 20 is slidably connected to the outer wall of the slide bar 3 18, the upper surface of the seat plate 1 is fixedly connected with a positioning ring 11, and the lower surface of the positioning ring 11 is fixedly connected with a gate sleeve 12 and a gate sleeve The outer wall of 12 is fixedly connected to the inside of the seat plate 1, the other end of the gate sleeve 12 is fixedly connected to the inside of the hot runner system 5, the inside of the seat plate 1 is fixedly connected with a reset rod 13, the middle part of the outer wall of the reset rod 13 is arranged in the inside of the hot runner manifold 2 and the stripper plate 3 in sequence, the bottom of the outer wall of the reset rod 13 is arranged in the inside of the fixed side template 4, the inside of the fixed side template 4 is fixedly connected with a guide column seat 14, the inside of the guide column seat 14 is slidably connected with a guide column 15, the outer wall of the guide column 15 is fixedly connected to the lower surface of the hot runner manifold 2, and the outer wall of the guide column 15 is slidably connected to the inside of the stripper plate 3;

[0026] Specifically, when the mold is in use, the slide bar 16 on the outer wall of the seat plate 1 and the slide bar 2 17 on the outer wall of the hot runner manifold plate 2 slide on the inner wall of the limit plate 19, thereby achieving precise limiting of the seat plate 1 and the hot runner manifold plate 2. At the same time, the other two slide bars 17 on the outer wall of the hot runner manifold plate 2 and the slide bar 3 18 on the outer wall of the discharge plate 3 slide together inside the limit plate 20, thereby completing the limiting of the hot runner manifold plate 2 and the discharge plate 3. During the movement of the hot runner manifold plate 2, the guide column 15 will slide inside the guide column seat 14, and the reset rod 13 will accurately control the guidance between the seat plate 1, the hot runner manifold plate 2, the discharge plate 3 and the fixed side template 4, thereby achieving the purpose of improving production quality.

[0027] Working principle: When it is necessary to use a mold improvement mechanism that improves production quality and reduces waste, first, on the basis of the structure of a conventional three-plate mold, add a hot runner manifold plate 2 connected to the seat plate 1, so that the hot runner system 5 is part of the three-plate mold fixed plate. In order to reduce waste as much as possible, the hot nozzle protection block 6 is raised to the back of the fixed side core 8 and fixed to the unloading plate 3. The hot nozzle 9 of the hot runner system 5 is embedded in the hot runner system 5. When the mold is opened, it slides a small distance with the side wall of the hot nozzle protection block 6 with the mold opening action to disconnect from the waste, and finally the waste is taken out by the robot. This improved mechanism simplifies the traditional front sprue 7 to the state of the improved sprue 7 after eliminating the waste of the main glue inlet of the sprue 7. The saving of waste from the sprue 7 is obvious to the naked eye;

[0028] In addition, when using the mold, the slide bar one 16 on the outer wall of the seat plate 1 slides on the inner wall of the limit plate one 19 with the slide bar two 17 on the outer wall of the hot runner manifold plate 2, so as to realize the limit between the seat plate 1 and the hot runner manifold plate 2. At the same time, the other two slide bars two 17 on the outer wall of the hot runner manifold plate 2 and the slide bar three 18 on the outer wall of the unloading plate 3 slide together inside the limit plate two 20, so as to realize the limit between the hot runner manifold plate 2 and the unloading plate 3. Finally, when the hot runner manifold plate 2 moves, it drives the guide pillar 15 to slide inside the guide pillar seat 14, and at the same time cooperates with the reset rod 13 to guide between the seat plate 1, the hot runner manifold plate 2, the unloading plate 3 and the fixed side template 4.
