Description

Technical Field

[0001] The utility model relates to the technical field of die-casting molds, in particular to a die-casting mold for a motor end cover. Background Art

[0002] The die-casting forming principle of the motor end cover mainly involves using die-casting technology to produce the end cover. Die-casting is a metal casting process. In the prior art, when the die-casting mold for the motor end cover is in use, the product will be formed inside the mold after die-casting. At present, most molds do not have the function of automatic demoulding, and the product is easy to get stuck inside the mold, and it is difficult to demould after the product is formed in the mold. Currently, when demoulding, springs and ejector rods are usually installed at the bottom of the mold. After the mold closing is completed, the spring rod pushes the ejector rod to move upward to achieve demoulding. However, the spring has a fatigue strength, and after multiple pressings, it is easy to cause damage to the spring, affecting the ejection of the material. For this reason, we propose a die-casting mold for a motor end cover to facilitate the protection of the ejection spring when demoulding the formed motor end cover. Summary of the Utility Model

[0003] Aiming at the problems in the prior art, the utility model provides a die-casting mold for a motor end cover.

[0004] The technical solution adopted by the utility model to solve its technical problems is a die-casting mold for a motor end cover, which includes a bottom plate. An ejection mechanism is installed at the top of the bottom plate. The ejection mechanism is composed of a bottom mold, a damping spring, a vertical rod, a horizontal plate, a moving plate, an ejector rod, a spring sleeve and a positioning rod. The bottom mold is installed at the top of the bottom plate. A group of symmetric vertical rods are installed on the outer wall of the bottom mold. The group of vertical rods respectively penetrate through the damping spring and the horizontal plate. The wall of the horizontal plate and the wall of the moving plate are connected by two groups of spring sleeves. Two groups of symmetric positioning rods are installed at the top of the moving plate. The two groups of positioning rods penetrate through the two groups of spring sleeves. The ejector rod is welded at the top of the moving plate. The ejector rod penetrates through the bottom mold.

[0005] By adopting the above technical solution, when taking the formed motor end cover, since a blanking mechanism is installed at the top of the bottom plate, the blanking mechanism is composed of a bottom die, a damping spring, a vertical rod, a cross plate, a moving plate, a blanking rod, a spring sleeve and a positioning rod. When the top plate is driven by an external press to move downward, the top plate squeezes the cross plate, so that the cross plate squeezes the damping spring at the vertical rod. The damping spring is used to prevent damage when the top die and the bottom die are clamped when the pressure is too high. Since the cross plate and the moving plate are connected by a spring sleeve, and the positioning rod penetrates through the spring sleeve and the cross plate, the spring sleeve is limited by the positioning rod, so that the moving plate moves downward. When the top die and the bottom die are opened, the damping spring pushes the cross plate upward, so that the cross plate drives the moving plate, and the moving plate drives the blanking rod upward, so that the blanking rod pushes the formed motor end cover in the bottom die to be demolded. Through the damping and shock absorption of the damping spring, the protection of the spring sleeve is realized, and the fatigue damage caused by multiple squeezes of the spring sleeve is avoided, and the spring sleeve needs to be replaced many times.

[0006] Specifically, it further includes a support mechanism, and the support mechanism is installed at the bottom of the bottom plate.

[0007] By adopting the above technical solution, the bottom plate can be supported and connected through the support mechanism.

[0008] Specifically, the support mechanism is composed of a Z-shaped plate, a threaded hole, a transverse groove and a locking bolt. Threaded holes are provided in the wall of the bottom plate and the wall of the Z-shaped plate, and a locking bolt is threadedly connected in the threaded hole. A transverse groove is provided in the wall of the Z-shaped plate.

[0009] By adopting the above technical solution, when supporting and connecting the bottom plate, since a support mechanism is installed at the bottom of the bottom plate, and the support mechanism is composed of a Z-shaped plate, a threaded hole, a transverse groove and a locking bolt. Since threaded holes are provided in the wall of the Z-shaped plate and the wall of the bottom plate, after the locking bolt is threadedly connected to the threaded hole, the Z-shaped plate is fixed at the bottom of the bottom plate. Since a transverse groove is provided in the wall of the Z-shaped plate, an external bolt is passed through the transverse groove and connected to the outside, so as to realize the support connection of the bottom plate.

[0010] Specifically, a group of the vertical rods penetrate through the top plate.

[0011] By adopting the above technical solution, the top plate can be limited by the vertical rod.

[0012] Specifically, a top die is installed at the bottom of the top plate.

[0013] By adopting the above technical solution, it is convenient to clamp the top die and the bottom die to form the motor end cover.

[0015] (1) A die-casting mold for a motor end cover according to the present utility model. When taking out the formed motor end cover, since a blanking mechanism is installed at the top of the bottom plate, the blanking mechanism is composed of a bottom mold, a damping spring, a vertical rod, a cross plate, a moving plate, a blanking rod, a spring sleeve and a positioning rod. When the top plate is driven by an external press to move downward, the top plate squeezes the cross plate, so that the cross plate squeezes the damping spring at the vertical rod. The damping spring is used to prevent damage when the top mold and the bottom mold are closed when the pressure is too high. Since the cross plate and the moving plate are connected by a spring sleeve, and the positioning rod passes through the spring sleeve and the cross plate, the spring sleeve is limited by the positioning rod, so that the moving plate moves downward. When the top mold and the bottom mold are opened, the damping spring pushes the cross plate upward, so that the cross plate drives the moving plate, and the moving plate drives the blanking rod upward, so that the blanking rod pushes the formed motor end cover in the bottom mold to be demolded. Through the damping and shock absorption of the damping spring, the protection of the spring sleeve is realized, and the fatigue damage caused by multiple squeezes of the spring sleeve is avoided, and the spring sleeve needs to be replaced many times.
