Description

Technical Field

[0001] This utility model relates to the field of mold core pulling technology, and in particular to a cross-directional slide core pulling mechanism. Background Technology

[0002] Injection molds are tools used to produce plastic products and have a wide range of applications. In the injection molding of plastic products, some plastic products have holes or grooves in three directions inside, which require core pulling in three directions. Traditional core pulling mechanisms are difficult to meet the requirements, so this type of core pulling mechanism is designed.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this utility model is to provide a cross-directional core-pulling mechanism that is simple in structure, has high production efficiency, good core-pulling effect, good product quality, and strong practicality, so as to overcome the shortcomings of the prior art.

[0005] A cross-directional core-pulling mechanism designed for this purpose is characterized by comprising an inclined pulling block, a slider, an inclined pulling mating block, a driving block, a movable block, and an inclined guide post. The inclined pulling mating block is fixed on the moving template, and the inclined pulling block and the inclined pulling mating block are slidably connected. The slider is slidably disposed on the inclined pulling block. The movable block is mounted on the driving block, and the inclined guide post is mounted on the movable block, with the inclined guide post passing through the slider. When the core-pulling mechanism pulls the core, the driving block drives the inclined guide post to move in a first direction through the movable block. The inclined guide post drives the slider to move in a second direction. When the slider moves to the corresponding position, the moving template drives the inclined pulling mating block to move in the second direction, and the inclined pulling mating block drives the inclined pulling block and the slider to move in a third direction, thereby realizing the workpiece disengagement.

[0006] The bottom of the inclined pull block is provided with a T-shaped block, and the inclined pull mating block is provided with a T-shaped groove. The T-shaped block is slidably mounted on the T-shaped groove. The inclined pull mating block drives the inclined pull block and the slider to move in a third direction through the cooperation of the T-shaped groove and the T-shaped block.

[0007] A limit block is provided on the inclined block, and the slider is limited on the limit block when it moves to the corresponding position in the second direction.

[0008] The inclined block has a movable cavity, the slider is slidably mounted on the movable cavity, and the limit block is located at the bottom of the movable cavity.

[0009] The movable block is provided with mounting angled holes, and one end of the angled guide post is fixed to the mounting angled holes.

[0010] The slider has an obliquely oriented through hole, and the other end of the oblique guide post passes through the through hole.

[0011] A limit head is provided at one end of the inclined guide post, a first limit surface is provided on the inclined mounting hole, and a second limit surface is provided on the drive block. The limit head is positioned between the first limit surface and the second limit surface.

[0012] The drive block is installed on the driver.

[0013] The bottom of the drive block is provided with a post that passes through the movable cavity. The bottom of the slider is provided with a first guide slope and one end of the post is provided with a second guide slope. When the drive block drives the post to move in the first direction, the slider moves in the second direction with the cooperation of the first guide slope and the second guide slope.

[0014] The T-blocks and T-slots are set at an angle.

[0015] The cross-directional sliding core-pulling mechanism of this utility model utilizes a driving block to drive an inclined guide post to move in the first direction (to the right) via a movable block. This causes the inclined guide post to drive a slider to move in the second direction (downward). When the slider moves to the corresponding position, the moving template drives the inclined core-pulling mating block to move in the second direction. This causes the inclined core-pulling mating block to drive the inclined core-pulling block and the slider to move in the third direction (downward to the right), thereby realizing core-pulling of the workpiece in three different directions. This structure uses a sliding mechanism with a sliding mechanism, which has a good core-pulling effect and meets product requirements. Attached Figure Description
