Description

Technical Field

[0001] The utility model belongs to the technical field of injection molds, in particular to a manifold injection mold based on an injection mold for injection molding. Background Art

[0002] A manifold injection mold is a mold used in injection molding. It is mainly used to divert molten plastic material into different cavities during the injection molding process so as to produce multiple identical or different parts at the same time. This manifold injection mold can effectively improve production efficiency, reduce production costs, and ensure the quality and consistency of injection molded parts. Manifold injection molds are usually used to produce large quantities of injection molded parts, especially parts with high symmetry or complex shapes. By setting multiple diversion channels in the mold, the molten plastic material can be evenly diverted into different cavities, thereby ensuring that the size and quality of each injection molded part are basically consistent. In addition, the manifold injection mold can also be used to produce injection molded parts of various colors or materials. By setting different diversion channels in the mold, plastic materials of different colors or materials can be injected into different cavities respectively, thereby realizing one-time injection molding of parts of multiple colors or materials.

[0003] For example, a diverter plate injection mold based on an injection mold for injection molding is proposed with publication number CN216506601U. The water in the water tank enters the first groove through the telescopic tube and is diverted to both sides. It passes through the baffle and the heat dissipation fins, gives a thrust to the check valve, and then enters the groove in the fixed seat, flushes the inner frame, takes away the heat, enters the S-shaped pipe through the circulating water tank, and then returns to the water tank, so that the water forms a large circulation, greatly improving the heat dissipation efficiency and making the heat dissipation more uniform, thereby solving the problem that the cooling effect of the injection mold for the diverter plate at this stage is poor and the diverter plate is easily wrinkled during pressing; at the same time, the pipes and grooves passed through are all closed or the connections are closed, which can reduce water loss and save energy and protect the environment.

[0004] When the above device is in use, the water inside the water tank enters the first groove through the telescopic tube, and gives a thrust to the check valve to the inner groove of the fixed seat and flush the inner frame, and uses the S tube to form an overall circulation to prevent waste of water resources. It solves the problem that the cooling effect of the injection mold used for the diverter plate at this stage is poor, and the diverter plate is easily wrinkled during pressing. However, the device only focuses on the cooling effect of the mold, and ignores the fact that the mold needs to be picked up by the staff after the injection molding is completed. Usually, this process is more troublesome and reduces the overall work efficiency. Utility Model Content

[0005] In order to solve the problems raised in the above-mentioned background technology, the utility model provides a diverter plate injection mold based on the injection mold for injection molding, which drives the movable plate and the movable column to move downward as a whole through the lifting plate, and uses the inertia of the strong spring to restore the movable plate and the movable column to their original state, so that the injection-molded mold can protrude smoothly from the interior of the mold frame, thereby solving the trouble of the staff in the taking process and improving work efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a diverter plate injection mold based on an injection mold for injection molding, comprising a mold body, a lifting assembly installed inside the mold body, the lifting assembly comprising a fixed cylinder, a movable column, a strong spring and a movable plate, the interior of the fixed cylinder is in a cavity state, the outer surface of the movable column is movably connected to the inner wall of the fixed cylinder, the top surface of the strong spring is fixedly connected to the bottom surface of the movable column, the bottom surface of the strong spring is fixedly connected to the inner bottom wall of the fixed cylinder, and the bottom surface of the movable plate is fixedly connected to the top surface of the movable column.

[0011] Preferably, a lifting plate is fixedly mounted on the bottom surface of the movable plate, one end of the lifting plate extends to the inside of the groove, and both sides of the lifting plate are slidably connected to the inner wall of the A slide groove.

[0012] Preferably, a B slide groove is provided on one side of the fixed plate, and a limit plate is slidably mounted on the inner wall of the B slide groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model uses the arrangement of a movable plate, a lifting plate, a movable column and a strong spring, and uses the lifting plate to move the movable plate as a whole downward, so that the bottom surface of the movable plate contacts the inner bottom wall of the mold frame, and pushes the limit plate.

At the same time, it will drive the mold completed by injection molding inside the mold frame to move upward as a whole, so that the staff can quickly take the mold.

[0021] 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.

[0022] like Figures 1 to 5As shown, the utility model provides a diverter plate injection mold based on an injection mold for injection molding, including a mold body 1, a lifting assembly 2 is installed inside the mold body 1, the lifting assembly 2 includes a fixed cylinder 21, a movable column 22, a strong spring 23 and a movable plate 24, the interior of the fixed cylinder 21 is in a cavity state, the outer surface of the movable column 22 is movably connected to the inner wall of the fixed cylinder 21, the top surface of the strong spring 23 is fixedly connected to the bottom surface of the movable column 22, the bottom surface of the strong spring 23 is fixedly connected to the inner bottom wall of the fixed cylinder 21, and the bottom surface of the movable plate 24 is fixedly connected to the top surface of the movable column 22.

[0023] The above scheme is adopted: by setting the fixed cylinder 21, the stability of the movable column 22 is improved when it rises or falls, and by setting the strong spring 23, when the injection molding of the mold frame 12 is completed, the movable plate 24 can be restored to its original height by utilizing its own inertia, so that the mold after injection molding can be smoothly protruded from the interior of the mold frame 12, thereby facilitating the staff to take it.

[0024] like Figure 1 to Figure 2 As shown, the mold body 1 includes a fixed plate 11, a mold frame 12, a mold plate 13 and an injection molding cylinder 14. A groove is opened at the center of the top surface of the fixed plate 11, the bottom surface of the fixed cylinder 21 is fixedly connected to the inner wall of the groove, and the bottom surface of the mold frame 12 is fixedly connected to the top surface of the fixed plate 11, one end of the groove passes through the interior of the mold frame 12, the outer surface of the movable plate 24 is movably connected to the inner wall of the mold frame 12, and the two are closely connected, the bottom surface of the mold plate 13 and the inner wall of the mold frame 12 are adapted to each other, and the top surface of the mold plate 13 is fixedly connected to the output end of the injection molding cylinder 14.

[0025] The above scheme is adopted: by setting the groove, a space for the lifting plate 241 to move is provided, and by setting the A slide groove, the lifting plate 241 is made more stable during the movement. By setting the injection molding cylinder 14, starting the injection molding cylinder 14 can drive the mold plate 13 to move downward as a whole, so that the bottom surface of the mold plate 13 contacts the material inside the mold frame 12, and the pressure brought by the injection molding cylinder 14 is used to achieve the injection molding effect.

[0026] like Figures 3 to 5 As shown, a lifting plate 241 is fixedly installed on the bottom surface of the movable plate 24, one end of the lifting plate 241 extends to the inside of the groove, and both sides of the lifting plate 241 are slidably connected to the inner wall of the A slide groove, and a B slide groove is opened on one side of the fixed plate 11, and a limiting plate 111 is slidably installed on the inner wall of the B slide groove.

[0027] The above scheme is adopted: through the setting of the B slide groove, the limit plate 111 can be moved smoothly. Through the setting of the limit plate 111, the limit plate 111 is pushed to fix the position of the lifting plate 241 after movement, preventing the strong spring 23 from restoring the movable column 22 and the movable plate 24 to their original state due to its own inertia.

[0028] The working principle and use process of the utility model are as follows: first, the staff presses the lifting plate 241 downward, so that the movable plate 24 and the movable column 22 move downward as a whole under the drive of the lifting plate 241. At this time, the strong spring 23 continuously contracts under the movement of the movable column 22. When the bottom surface of the movable plate 24 contacts the inner bottom wall of the mold frame 12, the B slide groove is used to push the limit plate 111 to the left, so that the bottom surface of the limit plate 111 contacts the top surface of the lifting plate 241, thereby fixing the position of the lifting plate 241 and the movable plate 24.

[0029] Then, start the injection molding cylinder 14 and use the output end of the injection molding cylinder 14 to drive the mold plate 13 to move downward as a whole, and contact with the material inside the mold frame 12, so as to perform injection molding. When the injection molding is completed, use the B slide groove to push the limit plate 111 to the terminal, so that the lifting plate 241 is separated from the fixation of the limit plate 111. At this time, after losing the pressure of the limit plate 111, the strong spring 23 uses its own inertia to move the movable column 22 and the movable plate 24 to their original positions, so that the mold inside the mold frame 12 is driven by the movable plate 24. The top surface can smoothly protrude from the inside of the mold frame 12, thereby facilitating the staff to better take it. At this point, the overall operation process is completed.
