二次抽芯机构及模具

Abstract

一种二次抽芯机构及模具，上模板设有第一导向件和第二导向件；第一芯块和第二芯块均可滑动地设置于下模板上，第一芯块与第一导向件滑动连接，第二芯块与第二导向件滑动连接；当上模板与下模板相互靠近时，在第一导向件驱动第一芯块沿第二方向滑动后，第二导向件驱动第二芯块沿第三方向滑动，以使第二芯块抵接于第一芯块上；当上模板与下模板相互远离时，在第二导向件驱动第二芯块沿第三方向滑动后，第一导向件驱动第一芯块沿第二方向滑动，以使第一芯块与第二芯块脱离。本申请中，通过第一芯块与第二芯块的二次抽芯，第一芯块和第二芯块沿预定方向进行滑动，使第一芯块和第二芯块不相干涉，便于第一芯块和第二芯块与产品脱模，提高了产品质量。

Claims

1. A secondary core-drawing mechanism, characterized by, include: Download template; An upper template is stacked on top of the lower template in a first direction, and the upper template is provided with a first guide and a second guide. Both the first core block and the second core block are slidably disposed on the lower template. The first core block is slidably connected to the first guide member, and the second core block is slidably connected to the second guide member. When the upper template and the lower template approach each other, after the first guide drives the first core block to slide along the second direction, the second guide drives the second core block to slide along the third direction, so that the second core block abuts against the first core block. When the upper template and the lower template move away from each other, after the second guide drives the second core block to slide along a third direction, the first guide drives the first core block to slide along a second direction, so that the first core block is separated from the second core block; The first direction, the second direction, and the third direction intersect each other.

2. The secondary core-drawing mechanism according to claim 1, characterized in that The first guide member includes a first guide post and a second guide post, the first guide post extending along the first direction, the second guide post being inclined relative to the first direction, and the second guide member being inclined relative to the first direction; The first direction is perpendicular to the second direction, and in the orthographic projection of the second direction, the second guide post is located below the second guide member.

3. The mechanism according to claim 2, wherein The secondary core-pulling mechanism further includes a first slider and a second slider. The lower template is provided with a first slide rail and a second slide rail. The first slider and the second slider are slidably disposed on the first slide rail and the second slide rail, respectively. The first slider has a first through hole, and the first guide is inserted into the first through hole. The second slider has a second through hole, and the second guide is inserted into the second through hole.

4. The mechanism of claim 3, wherein When the first guide post is inserted into the first through hole, the second guide member is inserted into the second through hole; When the second guide post is inserted into the first through hole, the second guide member separates from the second slider.

5. The mechanism of claim 3, wherein The first slide rail extends along the second direction, and the extension direction of the second slide rail is inclined relative to the first direction and the second direction.

6. The mechanism of claim 3, wherein In the second direction, one end of the first core block is connected to the first slider, one end of the second core block is connected to the second slider, and the other ends of the first core block and the other ends of the second core block together form the first parting surface.

7. The mechanism of claim 6, wherein In a direction perpendicular to the first direction and the second direction, a groove is provided on one side of the first core block, and a protrusion is provided on one side of the second core block, with the protrusion disposed in the groove.

8. The mechanism of claim 7, wherein The protrusion is provided with a first guide wall, and the groove is provided with a second guide wall. In the second direction, both the first guide wall and the second guide wall are inclined from top to bottom, and the first guide wall abuts against the second guide wall. When the upper template and the lower template approach each other, the first guide wall slides along the second guide wall, so that one end of the first core block and one end of the second core block form the first parting surface; When the upper template and the lower template move away from each other, the first guide wall slides along the second guide wall, so that the first core block and the second core block have a gap in the first direction.

9. The mechanism of claim 1, wherein The second core block is provided with a second parting surface, which is inclined relative to the first direction and the second direction.

10. A mold characterized in that, Includes the secondary core-pulling mechanism according to any one of claims 1-9.
