Description

Technical Field

[0001] The present application relates to the field of mold frame technology, and in particular to a motor housing mold frame. Background Art

[0002] The motor housing mold frame is the basic structure of the mold used to manufacture the motor housing. The mold frame is usually composed of top plate, bottom plate, guide pillar, guide sleeve, ejector plate, reset rod and other parts. The function of these parts is to fix the various parts of the mold and ensure the stability and accuracy of the mold during the processing.

[0003] At present, there are many new energy motor housing die-casting mold frames on the market, but the general new energy motor housing die-casting mold frames, when the device is used to fix the mold, the device cannot effectively buffer and release the impact force of the die-casting machine on the mold, resulting in the top of the mold frame being impacted and fed back by the impact force, causing serious damage to the device and greatly reducing the service life of the mold frame.

[0004] In response to the above technical problems, the patent with patent number CN214517510U discloses a die-casting mold frame for a new energy motor housing, which specifically relates to the field of mold frames, including a frame body, a groove is opened in the middle of the top of the frame body, the tops of the outer ring walls of the two guide rods are sleeved and connected with springs, the outer ring walls of the two guide rods are sleeved and connected with bottom plates, the tops of the two bottom plates are fixedly connected to one end of the corresponding springs, and the bottom ends of the two bottom plates are fixedly connected to the bottom ends of the inner walls of the corresponding grooves. The utility model is provided with a circular plate, a spring, a guide rod, and a circular groove, which is conducive to the circular plate to push the guide rod downward together with the impact force received, so that the circular plate squeezes the spring, and the spring contracts to release the impact force. The guide rod is subjected to external force and is sleeved and connected with the two circular grooves at the bottom ends of the corresponding grooves, which further buffers the impact force, thereby greatly reducing the impact force received by the device itself and effectively improving the service life of the device.

[0005] However, the above technical solution has the following defects:

[0006] (1) During the pressing process of the motor housing, the mold only has longitudinal pressure and lacks lateral pressure, which affects the quality of its pressing;

[0007] (2) During the pressing process of the motor housing, the mold lacks heat assistance, which reduces the efficiency of its deformation;

[0008] (3) During the pressing process of the motor housing, the mold is mostly single-point limited pressing, and multi-point limit pressing is not possible. During the long pressing process, it is easy to cause offset between the mold frames. Utility Model Content

[0009] One object of the present application is to provide lateral pressure during the pressing process, thereby improving the pressing quality.

[0010] In order to achieve the above purpose, the technical solution adopted by the present application is: a motor housing mold frame, including a mold, a protective inverted cone cover is movably connected to the top of the mold, an inner pressure mold is fixedly connected to the bottom of the protective inverted cone cover, a buffer pressing component is provided at the bottom of the inner pressure mold, a heat conducting component is provided above the inner wall of the inner pressure mold, and a multi-point auxiliary component is fixedly connected to the top of the protective inverted cone cover;

[0011] The buffer pressing assembly includes a positioning ring fixedly installed in the middle of the protective inverted cone cover, a connecting rod is movably connected inside the positioning ring, the lower end of the connecting rod passes through the protective inverted cone cover and is fixedly connected to a fixing plate, a surface of the fixing plate is movably connected to a plurality of auxiliary rods evenly distributed in a circumference, the other end of the auxiliary rod is movably connected to an auxiliary rotating frame, and the other end of the auxiliary rotating frame is movably connected to a heat conducting plate;

[0012] The heat conduction component comprises a protective plate fixedly installed below the connecting rod, a spiral heat conduction pipe is fixedly connected above the protective plate, a heat insulation plate is fixedly connected above the spiral heat conduction pipe, and the heat insulation plate is fixedly connected to the connecting rod;

[0013] The multi-point auxiliary component includes a hydraulic telescopic rod fixedly installed above the connecting rod, a positioning plate fixedly connected above the hydraulic telescopic rod, two first rotating frames symmetrically and evenly distributed and fixedly connected below the positioning plate, the other end of the first rotating frame is movably connected to a first rod, the other end of the first rod is movably connected to a relay rod, the other end of the relay rod is movably connected to a second rod, the other end of the second rod is movably connected to a second rotating frame, and the other end of the second rotating frame is movably installed above the protective inverted cone cover.

[0014] Further preferably, a spring telescopic rod is fixedly connected below the fixing plate, and the other end of the spring telescopic rod is fixedly mounted on the inner wall of the inner die.

[0015] Further preferably, an auxiliary plate is fixedly connected above the inner die, a plurality of limiting grooves are evenly distributed on the surface of the auxiliary plate in a circumferential manner, and the limiting grooves are movably connected to the heat conducting plate.

[0016] Further preferably, both sides of the positioning plate are symmetrically and evenly distributed and movably connected with a positioning rotating frame, and the other end of the positioning rotating frame is movably connected with a fixing rod.

[0017] Further preferably, the other end of the fixing rod is movably connected to an internally threaded frame plate, and outer walls of two adjacent internally threaded frame plates are movably connected to a sliding groove.

[0018] Further preferably, a bidirectional threaded rod is movably connected to the inner wall of the slide groove, the bidirectional threaded rod is movably connected to the internal threaded frame plate, and one end of the bidirectional threaded rod passes through the slide groove and is fixedly connected to a knob.

[0019] Further preferably, a bottom plate is fixedly connected below the two slide grooves, a plurality of positioning cylinders are fixedly connected in a rectangular and evenly distributed manner below the bottom plate, an elastic telescopic rod is fixedly connected above the inner wall of the positioning cylinder, and a buffer pad is fixedly connected below the elastic telescopic rod.

[0020] Compared with the prior art, the beneficial effects of this application are:

[0021] (1) The fixed plate continues to move downward through the continuous downward pressure of the hydraulic telescopic rod. With the cooperation of the auxiliary rod and the auxiliary rotating frame, the heat conducting plate is pushed to move toward the inner wall of the inner die, thereby providing lateral force for the pressing process of the motor housing. During the pressing process, the fixed plate moves downward and the spring telescopic rod is compressed. After the downward pressure of the hydraulic telescopic rod is lost, the fixed plate is driven upward by the spring telescopic rod that has lost pressure and returns to its original state, thereby providing lateral pressure during the pressing process, thereby improving the pressing quality.

[0022] (2) The heat conducting plate surrounding the fixed rod is heated to a certain degree by the spiral heating tube. Then, under the traction of the auxiliary rod, the heat conducting plate contacts the inner wall of the inner die to conduct heat rapidly. In this way, heat is conducted during the lateral pressing process, providing a certain amount of heat for the deformation of the motor shell during the pressing process, thereby improving the efficiency of the motor shell pressing process. In addition, during the lateral conversion pressing process, heat is simultaneously conducted to the inner die to ensure the efficiency of the motor shell pressing.

[0023] (3) As the hydraulic telescopic rod moves downward, it drives the fixed rod to move downward, so that the protective inverted cone cover moves downward with it. With the assistance of the first rotating frame and the second rotating frame, the angle between the first rod and the second rod gradually decreases, thereby cooperating with the downward movement of the protective inverted cone cover, driving the inner die to move downward and enter the mold, thereby enabling multi-point restrictions to be performed during the pressing process, preventing the mold frames from shifting due to long-term pressing operations, thereby affecting the quality of the pressing process.

[0043] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, a spring telescopic rod 32 is fixedly connected to the lower portion of the fixed plate 28, and the other end of the spring telescopic rod 32 is fixedly mounted on the inner wall of the inner die 14;

[0044] Specifically, the fixed plate 28 continues to move downward through the continuous downward pressure of the hydraulic telescopic rod 5, and with the cooperation of the auxiliary rod 27 and the auxiliary rotating frame 26, the heat conducting plate 25 is pushed to move toward the inner wall of the inner die 14, thereby providing lateral force for the pressing process of the motor housing. During the pressing process, the fixed plate 28 moves downward and the spring telescopic rod 32 is compressed. After the downward pressure of the hydraulic telescopic rod 5 is lost, the fixed plate 28 is driven upward by the spring telescopic rod 32 that has lost pressure and returns to its original state, thereby providing lateral pressure during the pressing process, thereby improving the quality of its pressing.

[0045] like Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, an auxiliary plate 23 is fixedly connected above the inner die 14, and a plurality of limiting grooves 24 are evenly distributed on the surface of the auxiliary plate 23 in a circumferential manner, and the limiting grooves 24 are movably connected to the heat conducting plate 25;

[0046] Specifically, after the heat conducting plate 25 surrounding the fixed rod 8 is heated to a certain degree by the spiral heating tube, the heat conducting plate 25 contacts the inner wall of the inner die 14 under the traction of the auxiliary rod 27 to quickly conduct heat, thereby conducting heat during the lateral pressing process, providing a certain amount of heat for the deformation of the motor shell during the pressing process, thereby being able to provide a certain amount of heat for the deformation of the motor shell during the pressing process, thereby improving the efficiency of the motor shell pressing process.

[0048] The other end of the fixing rod 8 is movably connected to an internal threaded frame plate 10, the outer walls of two adjacent internal threaded frame plates 10 are movably connected to a slide groove 9, the inner walls of which are movably connected to a bidirectional threaded rod 11, the bidirectional threaded rod 11 is movably connected to the internal threaded frame plate 10, and one end of the bidirectional threaded rod 11 passes through the slide groove 9 and is fixedly connected to a knob 12;

An elastic telescopic rod 21 is fixedly connected above the inner wall of the positioning cylinder 20, and a buffer pad 22 is fixedly connected below the elastic telescopic rod 21;

[0050] Specifically, during the downward movement of the hydraulic telescopic rod 5, the fixed rod 8 is driven to move downward, so that the protective inverted cone cover 2 follows the downward movement. With the assistance of the first rotating frame 15 and the second rotating frame 19, the angle between the first rod 16 and the second rod 18 is gradually reduced, thereby cooperating with the downward movement of the protective inverted cone cover 2 to drive the inner die 14 to move downward and enter the mold 1, so that multi-point restrictions can be performed during the pressing process to prevent the mold frames from shifting due to long-term pressing operations, thereby affecting the quality of the pressing process.
