一种立式压铸机的下模移出机构

Abstract

本实用新型公开了一种立式压铸机的下模移出机构，包括有由下往上依次设置在一机架上的下座板、下模、上模、上座板和尾板，以及位于下座板一侧的平移驱动装置；下模安装在下座板上，上模安装在上座板上，在下模与上模之间可形成浇注腔；在尾板上还设置有可用于驱动上座板上下移动的开合模驱动装置；平移驱动装置安装在机架上且其输出端连接下座板；平移驱动装置可用于驱动下座板在机架上水平移动，且平移驱动装置驱动下座板向外移动后，可使下座板与上座板之间相互错位。本实用新型可以使工作人员在取出工件时不需要再将手伸入至下模与上模之间，从而让工作人员可安全且方便地在下模中取出工件。

Claims

1. A lower mold removal mechanism for a vertical die-casting machine, characterized in that: It includes a lower base plate, a lower mold, an upper mold, an upper base plate and a tail plate arranged sequentially from bottom to top on a frame, as well as a translation drive device located on one side of the lower base plate; The lower mold is mounted on the lower base plate, and the upper mold is mounted on the upper base plate, forming a casting cavity between the lower mold and the upper mold; The tail plate is also provided with an opening and closing mold driving device for driving the upper seat plate to move up and down; The translation drive device is mounted on the frame and its output end is connected to the lower base plate; The translation drive device can be used to drive the lower seat plate to move horizontally on the frame, and after the translation drive device drives the lower seat plate to move outward, the lower seat plate and the upper seat plate can be misaligned.

2. The lower mold removal mechanism of the vertical die-casting machine according to claim 1, characterized in that: It also includes top material components; The ejector assembly includes an ejector cylinder mounted on the frame, an ejector pin that can move up and down through the lower mold, a movable plate that can move up and down in the mounting cavity of the lower mold and is connected to the bottom of the ejector pin, and springs whose two ends are respectively connected to the upper side wall of the mounting cavity and the top surface of the movable plate. After the translation drive device drives the lower seat plate to move outward, the output shaft of the ejector cylinder extends and passes through the first top hole of the lower seat plate and the second top hole of the lower mold respectively, until it extends to the mounting cavity. Then, it pushes the movable plate upward to drive the ejector pin to move upward into the casting cavity. When the output shaft of the ejector cylinder retracts, the spring drives the movable plate and the ejector pin to return to their original position downward.

3. The lower mold removal mechanism of the vertical die-casting machine according to claim 2, characterized in that: A limiting protrusion extending along the moving direction of the lower base plate is provided on the frame; a limiting groove corresponding to the limiting protrusion is provided on the bottom surface of the lower base plate; the limiting protrusion is fitted into the limiting groove.

4. The lower mold removal mechanism of the vertical die-casting machine according to claim 3, characterized in that: Two limiting protrusions are provided, and the two limiting protrusions are respectively located on both sides of the frame. Correspondingly, two limiting grooves are provided on both sides of the lower base plate.

5. The lower mold removal mechanism of the vertical die-casting machine according to claim 1, characterized in that: Dust scrapers are provided at both ends of the lower base plate; the lower end of the dust scraper extends downward from the lower base plate and abuts against the top surface of the frame.

6. The lower mold removal mechanism of the vertical die-casting machine according to claim 5, characterized in that: At least two evenly distributed dust scrapers are provided on each end face of the lower seat plate.

7. The lower mold removal mechanism of the vertical die-casting machine according to claim 1, characterized in that: The mold opening and closing drive device includes a mold opening and closing cylinder mounted on the tail plate shaft and two elbow assemblies respectively connected to the tail plate and the upper seat plate; the output shaft of the mold opening and closing cylinder can be connected to the two elbow assemblies through a connecting plate.

8. The lower mold moving mechanism of the vertical die casting machine according to claim 1, characterized in that: Four vertical columns are further arranged on the frame; four corners of the upper seat plate and the tail plate are respectively sleeved on the four vertical columns.

9. The lower mold moving mechanism of the vertical die casting machine according to claim 1, characterized in that: The translation driving device is an oil cylinder.
