Description

Technical Field

[0001] This utility model relates to the technical field of mold part fixing devices, specifically to a fixing device for mold part production. Background Technology

[0002] A mold is an industrial tool that shapes materials into a predetermined shape through a specific cavity structure. It is generally divided into four main parts: forming parts, ejection system, guiding parts, and auxiliary structures. The forming parts are further divided into mold cores, mold cavities, and front and rear mold cores, etc.

[0003] After the mold core is cast and formed, it is usually clamped and fixed on the machine tool by special fixtures for further processing. This means that different fixtures are often required when processing mold cores of different specifications and shapes. In addition, when installing the mold core, it is often necessary to place the mold core in a specific state, which reduces the fixing efficiency of the mold core. Utility Model Content

[0006] Several round rods are slidably inserted into corresponding storage slots at their bottoms. A piston plate is fixedly installed at the bottom end of each round rod, and the piston plate is arranged in a multi-faceted rod shape and contacts the inner wall of the corresponding storage slot.

[0007] The locking mechanism is located on the corresponding round rod and is used to lock the position of the mold core on the base plate.

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] See also Figure 1 - Figure 4 As shown, according to an embodiment of the present invention, a fixing device for producing mold parts is provided, including: a base plate 1, on which a plurality of storage slots 2 are provided at equal intervals on the top side; and an adjustment mechanism 3 is provided in the base plate 1 for adjusting the gas content in the storage slots 2.

[0031] Several round rods 4 are slidably inserted into the corresponding storage slots 2 at their bottoms. A piston plate 5 is fixedly installed at the bottom end of the round rods 4, and the piston plate 5 is arranged in a multi-faceted rod shape and contacts the inner wall of the corresponding storage slot 2.

[0032] The locking mechanism 7 is provided on the corresponding round rod 4 and is used to lock the position of the mold core on the base plate 1.

[0033] The monitoring mechanism 6 is located inside the base plate 1 and is used to monitor the position of the round rod 4 in the corresponding storage tank 2.

[0034] In this embodiment, when using the improved mold part production fixing device, the installation of the device can be completed by fixing the base plate 1 on the machine tool fixture mounting base with bolts;

[0035] Please refer to Figure 1 - Figure 3 As shown, when fixing the mold core, the operator directly places the mold core in the middle of the base plate 1. Due to the pressing of the mold core on the round rod 4, the round rod 4 at the corresponding position retracts into the storage groove 2. At this time, the monitoring mechanism 6 transmits the position information of the round rod 4 retracted into the storage groove 2 on the base plate 1 to the machine tool control host through the Internet of Things. Then, the internal program analyzes the point distribution of the round rod 4 retracted into the storage groove 2 on the base plate 1 to determine the position and orientation of the mold core on the base plate 1. When installing the mold core, it is not necessary to place the mold core in a specific state, which allows for a certain error and improves the fixing efficiency of the mold core.

[0036] Please refer to Figure 1 As shown, after the mold core is placed on the base plate 1, the round rod 4 located on the outer periphery of the mold core abuts against the mold core, and the mold core is multi-point limited by multiple positions on the outer periphery of the bottom of the mold core. Please refer to... Figure 1 - Figure 4 As shown, the gas content in the storage tank 2 is then increased by the adjustment mechanism 3, the locking mechanism 7 is activated, and the diameter of part of the round rod 4 is expanded. This allows for further mutual contact clamping at multiple points, locking the position of the mold core on the base plate 1. This prevents the mold core from being unable to form a tight mutual contact with the round rod 4 due to differences in size or shape, which would lead to unstable default fixation. This allows the device to adapt to the clamping and fixing of mold cores of different specifications and shapes, expanding the applicability of the mold core.

[0037] It should be noted that during the sliding process of the round rod 4 in the storage tank 2, the round rod 4 will not rotate due to the mutual contact between the piston plate 5 and the inner wall of the storage tank 2, which causes the locking mechanism 7 to undergo angular changes and affect the fixing effect of the mold core.

[0038] In a further preferred embodiment of this utility model, such as Figure 1 As shown, a magnetic plate 8 is fixedly installed on the top side of the base plate 1, and the magnetic plate 8 is located between several storage slots 2. The top side of the magnetic plate 8 is coplanar with the top side of the base plate 1.

[0039] In this embodiment, please refer to Figure 1 As shown, when the mold core is placed on the base plate 1 (at this time, the fixed mold core is made of a material that can generate attraction with the magnet), the magnetic plate 8 can be placed more stably on the base plate 1 due to the attraction of the mold core to the magnetic plate 8.

[0040] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the adjustment mechanism 3 includes a diversion channel 31, which is opened at the bottom of the base plate 1, and the bottom opening of the storage tank 2 communicates with the interior of the diversion channel 31.

[0041] An electrically controlled three-way valve 32 is fixedly installed on the side wall of the base plate 1, and one end of it near the base plate 1 is inserted into the diversion groove 31.

[0042] In this embodiment, please refer to Figure 1 - Figure 3 As shown, after the mold core is placed on the base plate 1, the electrically controlled three-way valve 32 is opened to allow external gas to be injected into the distribution groove 31 (the air inlet of the electrically controlled three-way valve 32 is connected to the exhaust port of the external gas injection device or the factory gas supply pipeline through a pipe), and the electrically controlled three-way valve 32 is closed after the gas content in the distribution groove 31 reaches the threshold (the control of the electrically controlled three-way valve 32 can be controlled by the machine tool host). As the gas flows into the distribution groove 31, some of the gas in the distribution groove 31 will flow into the storage tank 2, thereby achieving the purpose of synchronously adjusting the gas pressure in several storage tanks 2, so as to avoid the generation of pressure difference in several storage tanks 2, which would affect the fixing effect of the mold core;

[0043] After the machining of the machine tool mold core is completed, the electrically controlled three-way valve 32 is activated, which connects the inside of the diversion groove 31 with the outside. At this time, the excess air in the diversion groove 31 is discharged to the outside through the electrically controlled three-way valve 32, thereby releasing the fixed state between the base plate 1 and the mold core.

[0044] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 3As shown, the monitoring mechanism 6 includes several pressure sensors 61, which are respectively located below the corresponding piston plate 5 and fixedly connected to the inner bottom wall of the diversion groove 31, and the top of the pressure sensor 61 is fixedly connected to the corresponding piston plate 5 by a spring 62.

[0045] In this embodiment, please refer to Figure 2 and Figure 4 As shown, during the process of the round rod 4 retracting into the storage groove 2, a corresponding force can be applied to the pressure sensor 61 by the spring. At this time, the pressure change monitored by the pressure sensor 61 can be used to determine whether the round rod 4 is located at the bottom of the mold core.

[0046] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 As shown, the locking mechanism 7 includes a circular hole 71, which is opened at the axial position of the corresponding circular rod 4 and communicates with the interior of the diversion groove 31.

[0047] The outer peripheral wall of the round rod 4 has several storage slots 72 arranged in a circular array, and the interior of each storage slot 72 is connected to the interior of the corresponding round hole 71. A piston rod 73 is slidably installed in the storage slot 72, and the end of the piston rod 73 away from the corresponding round hole 71 is hemispherical.

[0048] In this embodiment, please refer to Figure 1 , Figure 2 As shown, as the pressure inside the storage tank 2 increases, since the storage tank 2 and the receiving tank 72 are connected by a circular hole 71, the gas inside the receiving tank 72 can apply a corresponding force to the piston rod 73, thereby causing part of the piston rod 73 to extend out of the receiving tank 72 and abut against the outer wall of the bottom of the mold core, further locking the position of the mold core on the base plate 1.

[0049] In a further preferred embodiment of this utility model, such as Figure 5 As shown, a second spring 74 is wound around the outer periphery of the piston rod 73, and the two ends of the second spring 74 are fixedly connected to the inner wall of the corresponding piston rod 73 and the corresponding storage groove 72, respectively.

[0050] In this embodiment, please refer to Figure 5 As shown, during the gas discharge process in the diversion groove 31, due to the push of the piston rod 73 by the spring 74, the piston rod 73 can be retracted into the receiving groove 72 in time, so as to avoid a part of the piston rod 73 always being outside the round rod 4 and affecting the subsequent installation of the mold core.

[0051] In a further preferred embodiment of this utility model, such as Figure 3 As shown, several positioning slots 75 are arranged in a circular array on the inner wall of the top opening of the storage tank 2, and each positioning slot 75 is shaped like an eighth of a sphere.

[0052] In this embodiment, please refer to Figure 3 As shown, as the air pressure in the storage tank 72 increases, the piston rod 73 located on the bottom side of the mold core is pushed by the gas, so that part of the hemispherical end of the piston rod 73 is inserted into the positioning groove 75, thereby increasing the friction between the piston rod 73 and the inner wall of the storage tank 2, so as to avoid the mold core being subjected to a large upward thrust, which would affect the fixation of the mold core.

[0053] Working principle: When fixing the mold core, the operator adjusts the orientation of the mold core and places it directly on the center position of the base plate 1. Due to the pressure of the mold core on the round rod 4, the round rod 4 at the corresponding position retracts into the storage groove 2. The spring 62 applies a pressure of corresponding intensity to the pressure sensor 61 at the corresponding position. At this time, the information is transmitted to the machine tool's control host. Subsequently, the internal program analyzes and forms the point distribution of the round rod 4 retracted into the storage groove 2 on the base plate 1, thereby determining the position and orientation of the mold core on the base plate 1.

[0054] After the mold core is placed on the base plate 1, the round rod 4 located on the outer periphery of the mold core abuts against the mold core. The mold core is multi-point limited by multiple positions on the outer periphery of the bottom of the mold core. At the same time, the electric three-way valve 32 is opened to allow external gas to be injected into the diversion groove 31. After the gas content in the diversion groove 31 reaches the threshold, the electric three-way valve 32 is closed. As the gas flows into the diversion groove 31, the gas pressure in the receiving groove 72 will rise synchronously. At this time, part of the piston rod 73 will slide out from the receiving groove 72 and abut against the bottom outer wall of the mold core, thereby locking the position of the mold core on the base plate 1. The fixing of the mold core is completed.

[0055] After the machine tool finishes processing the mold core, the electrically controlled three-way valve 32 is activated, which connects the inside of the diversion groove 31 with the outside. At this time, the excess air in the diversion groove 31 is discharged to the outside through the electrically controlled three-way valve 32. Due to the push of the piston rod 73 by the second spring 74, the piston rod 73 automatically retracts into the storage groove 72 to release the fixed state of the mold core. At this time, the mold core can be directly removed from the base plate 1. After the mold core is removed from the base plate 1, due to the push of the round rod 4 by the first spring 62, the round rod 4 retracted into the storage groove 2 automatically pops out.

[0056] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0057] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above are only preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
