Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a magnetic mold locking mechanism. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, molds are tools used to create shaped objects. These tools are composed of various parts, and different molds are composed of different parts. They mainly achieve the processing of the shape of the object by changing the physical state of the material being molded. In the opening and closing process of existing molds, in order to obtain a better mold matching structure, mold locking buckles are often required to achieve precise matching of the templates when closing the mold and good separation of the templates when opening the mold.

[0003] Existing magnetic mold locking technology uses magnets on the upper and lower fixed blocks. After the two magnets attract each other, they can only be separated with difficulty by a large external force. During the separation process, the excessive pulling force can easily cause the parts to loosen or detach, making it impossible to achieve a good separation between the moving and fixed mold plates in the mold. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a magnetic mold-locking mechanism for the rapid locking and separation of the moving and fixed mold plates in a mold. The purpose is to solve the problem that in existing magnetic mold-locking buckles, magnets are set on the upper and lower fixed blocks respectively. After the two magnets attract each other, they can only be separated with difficulty under the action of a large external force. Moreover, during the separation process, the excessive pulling force can easily cause the parts to loosen or detach.

[0005] To achieve the above objectives, this magnetic mold-locking mechanism is implemented through the following technical solution:

[0006] A magnetic mold-locking mechanism includes a mold-locking body and a suction plate. The suction plate is disposed above the mold-locking body. A core is disposed inside the mold-locking body. A magnet is disposed between the core and the mold-locking body. A magnet cover plate is disposed at the top of the magnet. The top edge of the core is pressed against the magnet cover plate to fix the magnet inside the mold-locking body. The core is fixed inside the mold-locking body by setting a locking fastener. In the mold-closed state, the suction plate forms an adsorption connection with the mold-locking body through the magnetic force of the magnet.

[0007] Furthermore, a magnet tray is provided at the bottom of the magnet, the inner diameter of which matches the outer diameter of the core, and the magnet tray is fixed together with the core inside the mold body by fasteners.

[0008] Furthermore, the outer edge of the top of the core is provided with an outwardly extending pressing part, and the inner edge of the top of the magnet cover is provided with a downwardly recessed step. The pressing part matches the step, and the bottom surface of the pressing part and the top surface of the step form a planar pressing structure.

[0009] Furthermore, the magnet is a cylindrical structure or a semi-circular arc structure with two halves.

[0010] Furthermore, the transverse surfaces of the mold-locking body and the suction plate are provided with connecting holes and screws, which are used to connect the mold-locking body to the fixed template and the suction plate to the moving template.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] A magnetic mold-locking mechanism is provided, including a mold-locking body and a suction plate. The mold-locking body has a core inside, and a magnet is placed between the core and the mold-locking body. This magnetic mold-locking mechanism only has one magnet inside the mold-locking body. When the mold is closed, the suction plate forms an attractive connection with the mold-locking body through the magnetic force of the magnet, thus achieving the mold-locking function through the attraction of the magnet. When the mold is opened, the suction plate can be easily separated from the mold-locking body by the mold opening pull force. By optimizing the magnet fixing structure and magnetic force distribution, low external force and high efficiency separation are achieved. This solves the problem of existing magnetic mold-locking buckles, which have magnets on the upper and lower fixing blocks respectively. After the two magnets attract each other, they require a large external force to separate them, and the excessive pulling force during the separation process can easily cause the parts to loosen or detach.

[0021] 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.

[0022] See Figure 1-7 As shown, this utility model provides a technical solution: a magnetic mold locking mechanism, including a mold locking body 1 and a suction plate 2. The suction plate 2 is disposed above the mold locking body 1. A core 3 is disposed inside the mold locking body 1. A magnet 4 is disposed between the core 3 and the mold locking body 1. A magnet cover plate 5 is disposed at the top of the magnet 4. The top edge of the core 3 is pressed against the magnet cover plate 5, so that the magnet 4 is fixed inside the mold locking body 1. The core 3 is fixed inside the mold locking body 1 by setting a locking fastener 6 (i.e., a screw). In the mold-closed state, the suction plate 2 forms an adsorption connection with the mold locking body 1 through the magnetic force of the magnet 4. This magnetic mold-locking mechanism achieves efficient separation with low external force by optimizing the magnet fixing structure and magnetic force distribution. It can achieve the mold-locking function through the attraction of magnet 4, and can also use the mold opening pull force to smoothly separate the suction plate 2 from the mold-locking body 1. This solves the problem of existing magnetic mold-locking buckles with magnets set on the upper and lower fixing blocks respectively. After the two magnets attract each other, they can only be separated with a large external force. Moreover, the excessive pulling force during the separation process can easily cause the parts to loosen or detach.

[0023] See Figure 1 As shown, a magnet tray 7 is provided at the bottom of the magnet 4. The inner diameter of the magnet tray 7 matches the outer diameter of the core 3. The magnet tray 7 is fixed together with the core 3 inside the mold body 1 by the locking fastener 6.

[0024] See Figure 2 As shown, the top edge of the core 3 has an outwardly extending pressing part 31, and the top edge of the magnet cover plate 5 has a downwardly recessed step 51. The pressing part 31 matches the step 51, and the bottom surface of the pressing part 31 and the top surface of the step 51 form a planar pressing structure, ensuring that the magnet is firmly fixed and the force is evenly distributed. Through the matching structure of the pressing part 31 and the step 51 of the core 3 and the magnet cover plate 5, combined with the fastening effect of the fastener 6, the displacement or falling off of the magnet 4 is effectively prevented, the service life is extended, and the structural stability is improved.

[0025] See Figure 1 As shown, magnet 4 is a cylindrical structure or a semi-circular structure with half of it set. The magnet structure can be selected as cylindrical or semi-circular arc according to actual needs to adapt to different mold sizes and magnetic strength requirements.

[0026] See Figure 6-7 As shown, the mold-locking body 1 and the suction plate 2 are provided with connecting holes 8 on their transverse surfaces and screws 9 are provided. The mold-locking body 1 is connected to the fixed template 10 and the suction plate 2 is connected to the moving template 11 by the screws 9.

[0027] Working principle: It needs to be explained that Figure 6 and Figure 7 The diagram shown illustrates the simplified usage of this magnetic mold-locking mechanism. The incomplete display of the specific structures of the fixed and moving mold units should not affect the normal operation of the mechanism. The mold-locking body 1 is fixed to the fixed mold plate 10 using screws 9, and the suction plate 2 is fixed to the moving mold plate 11. When the mold closes, the magnet 4 attracts the suction plate 2, locking the mold plates. After the product injection molding is complete, when the mold opens, a vertical external force is applied. The mold opening pull then smoothly separates the moving mold plate 11 and the suction plate 2 from the fixed mold plate 10 and the mold-locking body 1. This magnetic mold-locking mechanism achieves its locking function through the attractive force of the magnet 4, and also utilizes the mold opening pull to smoothly separate the suction plate 2 from the mold-locking body 1. By optimizing the magnet fixing structure and magnetic force distribution, low-force, high-efficiency separation is achieved.
