[ Detailed description ] of the invention
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1 to 8, an injection mold structure with an ejector pin comprises a mold core 1 and a row seat 2, wherein a row seat 3 which can be opened and closed relative to the mold core 1 is fixedly connected to the row seat 2, the ejector pin 4 which can slide in the row seat 3 is arranged in the row seat 3, a clearance groove 31 is also arranged in the row seat 3, a stop block 5 which can slide in the clearance groove 31 and is fixedly connected with the ejector pin 4 is arranged in the clearance groove 31, the width of the clearance groove 31 is larger than the thickness of the stop block 5, when the row seat 3 is matched with the mold core 1, the stop block 5 is abutted against the mold core 1, a yielding gap 311 is formed between the stop block 5 and the groove wall of the clearance groove 31, and a spring 6 which can push the ejector pin 4 to slide relative to the row seat when the row seat 2 is separated from the mold core 1 is arranged between the row seat 2 and the stop block 5, so that a product is separated from the row seat 3. When the line position is matched with the die core, because a yielding gap is formed between the stop block and the wall of the void-avoiding groove, the distance of the yielding gap is 4mm, and when the line position moves 4mm away from the die core, the spring pushes the stop block, the ejector pin stretches out from the line position, and the ejector pin pushes the product, so that the product is separated from the line position; when the moving distance of the row position is equal to 4mm, the stop block is attached to the wall of the clearance groove, and at the moment, the row position drives the stop block and the ejector pin to move together, and the product is taken out. Because the row position moves first and the thimble moves later, the product can be smoothly separated from the row position.
The invention has simple structure, can improve the stability of the product quality, prevent the product from being bad due to the sticking of the product, favorably ensure the smooth performance of the core pulling work of the product, has simple and reliable structure, improves the quality and the production efficiency of the product, and is suitable for popularization.
