Description

Technical Field

[0001] This utility model relates to the field of die-casting mold technology, specifically to an integrated die-casting mold for the front cover of a new energy vehicle motor. Background Technology

[0002] Die casting molds are the core equipment in die casting production. They are used to rapidly inject molten metal (such as aluminum alloys, zinc alloys, magnesium alloys, etc.) into the mold cavity under high pressure, and after cooling and solidification, form castings of the required shape and size. They consist of precision components such as a fixed mold, moving mold, core, slide block, gating system, and overflow system. Their complex structure must withstand the harsh conditions of high temperature, high pressure, and thermal fatigue. Die casting molds are widely used in the automotive, 3C electronics, and aerospace industries, featuring high production efficiency, good dimensional accuracy, and excellent surface quality. They are a key tool for modern manufacturing to achieve efficient, low-cost mass production.

[0003] Chinese patent CN214392288U discloses a side-pulling die-casting mold, including a fixed template, a fixed core, a moving template, a moving core, a sliding block, a first side-pulling component, a second side-pulling component, a first side-driving mechanism, a second side-driving mechanism, a feed nozzle, a top plate, and multiple ejector pins. The ejector pins sequentially pass through the moving template and the moving core. The fixed core, the moving core, the first side-pulling component, and the second side-pulling component form a die-casting cavity. One end of a connecting component is connected to the output end of the first side-driving mechanism, and the other end of the connecting component has an inclined guide groove. The first side-pulling component is inclined and slidably connected to the inclined guide groove. The second side-pulling component is connected to the second side-driving mechanism. This die-casting mold drives the first side-pulling component to move obliquely through the inclined guide groove, enabling the first side-pulling component to pull the core obliquely to the side. The first side-pulling component is less likely to shift or retract during mold closing or die-casting, allowing the mold to produce stably and continuously.

[0004] The die-casting mold described in the aforementioned patent document uses drive mechanisms on both sides of the moving mold. These two drive mechanisms then drive side core pullers via guide members, forming a complete mold cavity with the fixed mold core and the moving mold core. However, since the side core pullers are driven by two separate drive mechanisms, they cannot achieve synchronization. Therefore, a die-casting mold for an integrated front cover of a new energy vehicle motor is proposed. Utility Model Content

[0005] To address the aforementioned issues, a die-casting mold for an integrated front cover of a new energy vehicle motor is provided. This mold utilizes an inclined guide rod and an inclined hole to drive a moving base. As the moving base moves, it causes the side core-pulling component to slide along a pull-out groove, allowing it to enter the groove. When the fixed mold base and the moving mold base are fully closed, the inclined guide rod, in conjunction with the inclined hole, drives the moving base, which then delivers the side core-pulling component into the working area. This solves the problem of the side core-pulling component not being able to move synchronously with the fixed and moving mold bases.

[0006] To address the existing technical problems, this application provides an integrated die-casting mold for the front cover of a new energy vehicle motor, including a fixed mold base, a concave mold on the fixed mold base, a movable mold base disposed on one side of the fixed mold base, a punch disposed on the movable mold base, and a clamping mechanism disposed on both sides of the movable mold base, wherein the punch is symmetrically provided with pull-out grooves; The clamping mechanism includes a fixed frame fixed on two corresponding side walls of the moving mold base, a movable seat installed inside the fixed frame, an inclined hole opened on the movable seat, and a side core puller that can move along the pull groove fixed at one end of the movable seat. One side of the fixed mold base is fixed with an outwardly inclined guide rod, which is inserted into an inclined hole.

[0007] As a technical solution of this application, the fixed frame is provided with limiting grooves on both sides for limiting the movement of the movable seat; The movable seat has limit blocks fixed on both sides that can slide along the limit groove.

[0008] As one technical solution of this application, a trapezoidal seat is fixed on the side of the movable seat near the side core-pulling component; The fixed mold base has a trapezoidal groove on one side that can be adapted to the trapezoidal base.

[0009] As one technical solution of this application, overflow grooves that can communicate with the mold cavity are provided on both sides of the punch; The moving mold base is fixed with a pre-collection device on both sides. The pre-collection device includes a first fixed base and a collection cavity is opened in the first fixed base. The collection device is expected to include a second fixed seat that can close the first fixed seat, the second fixed seat being fixed to both sides of the mold base.

[0010] As one technical solution of this application, a plurality of limiting guide rods are symmetrically fixed on one side of the fixed mold base; A limiting sleeve is installed inside one side of the moving mold base, and a limiting guide rod can be installed inside the limiting sleeve.

[0011] As one technical solution of this application, the fixed mold base is equipped with a casting pipe that can communicate with the mold cavity.

[0012] The advantages of this utility model compared to the prior art are: 1. This application utilizes an inclined guide rod and an inclined hole to drive the moving seat. As the moving seat moves, it causes the side core-pulling component to slide along the pull-out groove, thus allowing the side core-pulling component to enter the pull-out groove. When the fixed mold base and the moving mold base are fully closed, the inclined guide rod, in conjunction with the inclined hole, drives the moving seat, which then sends the side core-pulling component into the working area, solving the problem that the side core-pulling component cannot move synchronously with the fixed mold base and the moving mold base.

[0013] 2. This application utilizes a collection cavity opened in the first fixed seat, which is connected to the mold cavity through an overflow groove. When the motor front cover is poured, excess pouring liquid in the mold cavity will flow into the collection cavity through the overflow groove, effectively preventing excess pouring liquid remaining in the mold cavity from not being cleaned in time, which could lead to defects on the surface of the casting or incomplete internal structure, affecting product performance.

Detailed Implementation

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. See Figures 1-7 As shown, a die-casting mold for an integrated front cover of a new energy vehicle motor includes a fixed mold base 1, a concave mold 15 on the fixed mold base 1, a movable mold base 2 disposed on one side of the fixed mold base 1, a punch 22 disposed on the movable mold base 2, and a clamping mechanism 4 disposed on both sides of the movable mold base 2. The punch 22 is symmetrically provided with pull-out grooves 24. The clamping mechanism 4 includes a fixed frame 41 fixed on two corresponding side walls of the moving mold base 2. A movable seat 42 is installed inside the fixed frame 41. An inclined hole 422 is opened on the movable seat 42. A side core puller 5 that can move along the pull groove 24 is fixed at one end of the movable seat 42. An outwardly inclined guide rod 12 is fixed on one side of the fixed mold base 1, and the inclined guide rod 12 is inserted into the inclined hole 422.

[0023] During the closing process of the moving mold base 2 and the fixed mold base 1, the moving mold base 2 will drive the clamping mechanism 4 to gradually approach the fixed mold base 1. The inclined guide rod 12 fixed on the fixed mold base 1 will move along the central axis of the inclined hole 422. At this time, the inclined guide rod 12 and the inclined hole 422 cooperate to drive the moving seat 42 to move. While the moving seat 42 moves, it will drive the side core puller 5 to slide along the pull groove 24, thereby allowing the side core puller 5 to enter the pull groove 24. When the fixed mold base 1 and the moving mold base 2 are completely closed, the inclined guide rod 12 drives the moving seat 42 through cooperation with the inclined hole 422, and then the moving seat 42 sends the side core puller 5 into the working area, which solves the problem that the side core puller 5 cannot move synchronously with the fixed mold base 1 and the moving mold base 2.

[0024] See Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown, the fixed frame 41 has limiting grooves 411 on both sides for limiting the movement of the movable seat 42. The movable seat 42 has limit blocks 421 fixed on both sides, which can slide along the limit groove 411.

[0025] To ensure the stability of the movable seat 42, limiting blocks 421 are symmetrically fixed on both sides of the movable seat 42. When the movable seat 42 moves, it will slide along the limiting groove 411 through the limiting blocks 421. The limiting blocks 421 and the limiting groove 411 slide together to limit the movable seat 42, thereby ensuring the stability of the movable seat 42.

[0026] See Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, a trapezoidal seat 43 is fixed on the side of the movable seat 42 near the side core puller 5; A trapezoidal groove 14 that can be adapted to the trapezoidal seat 43 is provided on one side of the fixed mold base 1.

[0027] To ensure the stability of the side core-pulling component 5, a trapezoidal seat 43 is fixed to one side of the movable seat 42, and a trapezoidal groove 14 is formed on one side of the fixed mold base 1. When the movable mold base 2 drives the clamping mechanism 4 to approach the fixed mold base 1, the trapezoidal seat 43 slides along the inner wall of the trapezoidal groove 14. The trapezoidal seat 43 and the trapezoidal groove 14 limit the movable seat 42, effectively preventing the movable seat 42 from causing the side core-pulling component 5 to shift. This ensures the stability of the side core-pulling component 5.

[0028] See Figure 3 , Figure 5 and Figure 6 As shown, overflow grooves 23 that can communicate with the mold cavity are provided on both sides of the punch 22; The moving mold base 2 is fixed with a pre-collection device 3 on both sides. The pre-collection device 3 includes a first fixed base 31, and a collection cavity 311 is opened in the first fixed base 31. The expected collection device 3 also includes a second fixed seat 32 that can close the first fixed seat 31, and the second fixed seat 32 is fixed on both sides of the fixed mold seat 1.

[0029] When the fixed mold base 1 and the moving mold base 2 are closed, the second fixed base 32 fixed on the fixed mold base 1 and the residual material collection device 3 fixed on the moving mold base 2 will be completely closed. At this time, the collection cavity 311 opened in the first fixed base 31 will be connected to the mold cavity through the overflow groove 23. When pouring the motor front cover, the excess pouring liquid in the mold cavity will flow into the collection cavity 311 through the overflow groove 23, effectively avoiding the inability to clean the excess pouring liquid remaining in the mold cavity in time, which would cause defects on the surface of the casting or incomplete internal structure, affecting the product performance.

[0030] See Figure 4 and Figure 5 As shown, a plurality of limiting guide rods 13 are symmetrically fixed on one side of the fixed mold base 1; A limiting sleeve 21 is installed inside one side of the moving mold base 2, and the limiting guide rod 13 can be installed inside the limiting sleeve 21.

[0031] To ensure precise closure of the fixed mold base 1 and the moving mold base 2, a gating pipe 11 is installed on one side of the fixed mold base 1, and a limiting sleeve 21 is installed on one side of the moving mold base 2. When the moving mold base 2 approaches the fixed mold base 1, the moving mold base 2 will drive the limiting sleeve 21 to move synchronously. At this time, the limiting guide rod 13 is inserted into the limiting sleeve 21. The limiting sleeve 21 and the limiting guide rod 13 work together to limit the fixed mold base 1 and the moving mold base 2, thereby ensuring precise closure of the fixed mold base 1 and the moving mold base 2.

[0032] See Figure 1 , Figure 2 and Figure 5 As shown, a gating pipe 11 that can communicate with the mold cavity is installed on the fixed mold base 1.

[0033] The gating pipe 11 is fixed on the fixed mold base 1. During pouring, the pouring liquid is delivered to the mold cavity through the gating pipe 11.

[0034] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
