Angle pin mechanism

Abstract

The invention discloses an angle pin mechanism. The angle pin mechanism can be utilized for production of a mold. The mold comprises a mother plate, a core plate, an upper liftout plate, a lower liftout plate and a fixing plate. The angle pin mechanism comprises an angle pin arranged in the core plate, wherein an end surface of the angle pin is patched with a cavity of the mother plate and a side of the angle pin is provided with a chute, an ejector pin, wherein one end of the ejector pin is arranged in the upper liftout plate and the other end of the ejector pin is arranged in the core plate and contacts with the other end surface of the angle pin, and a stop pin, wherein the stop pin is located in the core plate and an end of the stop pin is arranged in the chute of the angle pin. The angle pin mechanism occupies a small use space in the mold, has simple processes and high strength, and is convenient for assembling, installation and dismounting of the mold.

Description

【Technical field】 [0001] The invention relates to an oblique pin mechanism, in particular to an oblique pin mechanism capable of enhancing the strength of the oblique pin and facilitating mold repair and design. 【Background technique】 [0002] In the existing mold production, some products are often formed by slanting pins, and when encountering some structures with a small mold space, the slanting pins used are often small in section and long in length, which will lead to Slanted pins are not strong enough in mold production and are easy to break, which brings a lot of trouble and inconvenience to mold production. In addition, there is another kind of slanted pin mechanism consisting of slanted pins and thimbles. Specifically, the existing existing oblique pin mechanism is as follows: [0003] figure 1 A structural schematic diagram of the first existing oblique pin mechanism is shown. [0004] refer to figure 1 As shown, the existing oblique pin mechanism is used in th...

Problems solved by technology

[0008] In the above-mentioned oblique pin mechanism, the first hook 201 and the second hook 211 are needed when the oblique pin 20 and the thimble 21 are required. The strength of the junction of the two hooks is poor and easy to break. At the same time, if the gap is too large, glue will be added to the finished product or the oblique pin will not be able to withdraw. The processing accuracy is very high, and the countersunk head 212 needs a pin edge to prevent rotation, which will increase the mold processing process and increase the cost. In addition, in mold repair In the design and transformation, there are often oblique pins to be reprocessed, and the oblique pins need to be removed from the formwork. In this way, the fixing plate needs to be removed and the plate is ejected, which takes a lot of manpower and time.
