Embodiment Construction

[0016] see figure 2 As shown, it depicts a schematic diagram of the mold clamping state of the two-stage oblique pin of the present invention. The two-stage oblique pin of the present invention is applied in a mold, and the two-stage oblique pin includes:

[0017] Slanted pin seat 400, which is located in the upper ejection plate 40 of the above-mentioned mould;

[0018] The first section of the oblique pin 300 has one end set on the above-mentioned oblique pin seat 400, and the other end is provided with a groove 310. In this embodiment, the groove 310 is a dovetail groove;

[0019] The second section of oblique pin 200, which is arranged on the above-mentioned first section of oblique pin 300, the second section of oblique pin 200 is provided with a stop pin 210, and one end of the stop pin 210 is arranged in the above-mentioned groove 310, and placed on the mold When the mold is closed, the stop pin 210 is in contact with one side of the groove 310 , and the second secti...

Abstract

The invention relates to a two-section angle pin that is applied to a mold. The two-section angle pin comprises: an angle pin seat, which is disposed in an upper ejector plate of the mold; a first section angle pin, one end of which is arranged on the angle pin seat and the other end of which is provided with a groove; a second section angle pin, which is mounted on the first section angle pin and provided with a stop pin, with one end of the stop pin located in the groove. For the two-section angle pin of the invention, when producing a product having an undercut at an inverse hook in the angle pin exit direction, the first section angle pin makes tilt movement to exit from the inverse hook of the product, and the second section angle pin makes vertical movement so as to make the two-section angle pin exit smoothly, thus finishing a demolding action.

Description

【Technical field】 [0001] The invention relates to an oblique pin, in particular to a two-stage oblique pin. 【Background technique】 [0002] In the production of plastic products, the barbs on the inner side of the plastic products and the barbs with smaller shapes are generally withdrawn by oblique pins. It is widely used in molds. [0003] However, in the production of plastic products, sometimes due to the limitation of the structure of the plastic product, there will be an undercut in the exit direction of the oblique pin at the undercut of the product. Please refer to figure 1 , which shows a schematic diagram of a product with an undercut in the exit direction of the oblique pin. Because the product 10 is provided with an undercut 12 in the exit direction of the oblique pin at the undercut 11, the oblique pin cannot be withdrawn, and the product cannot be removed from the mold, causing troubles in mold design. [0004] In view of this, it is necessary to develop a ne...
