Embodiment Construction

[0013] refer to figure 2 , which is a cross-sectional view of the invention in the mold clamping state, the oblique pin return mechanism of the female mold includes a thimble 222 that can pass through the male mold 22 and enter the female mold 21, and one end of the thimble 222 is accommodated in the male mold. In the groove 221 of the second spring 26, the other end pushes a slanted pin 23, which is arranged on the side of the cavity 211 of the female die 21, and includes a thimble pin 222 pushed in the cavity. The force receiving part 231 that moves in 211, and the opposite side of the force receiving part 231 and the thimble 222 interferes with the first spring 25, and one end of the force receiving part 231 is bent into a continuous line according to the shape of the product 24 (including its barb 241). Moving part 232.

[0014] When opening the mold, please refer to figure 2 , image 3 , the male mold 22 moves down, the first spring 25 releases the pressure, the incl...

Abstract

The invention discloses a female mold inclined pin return mechanism, comprising an ejector pin which can pass through a male mold to a female mold. One end of the ejector pin is held in a groove formed by depression of the surface of the male mold and interferes with a second spring, the other end of the ejector pin pushes an inclined pin that is arranged at the side of the cavity of the female mold, the inclined pin comprises a force-bearing part that is pushed by the ejector pin to move in the cavity, the surface of the force-bearing part reverse to the ejector pin interferes with a first spring, and one end of the force-bearing part is bent into an interlocking part according to the shape of a product. On the basis of an original female mold inclined pin, the ejector pin is added on the surface of the male mold, and the inclined pin is returned earlier than the male mold owning to the elasticity of the spring when matching molds, thus avoiding the damage to the mold caused by the collision between the inclined pin and the male mold. The mechanism also has the advantages of simple structure, high reliability, low cost and easy processing.

Description

【Technical field】 [0001] The present invention relates to a tilt pin return mechanism of a master mold, in particular to a tilt pin return mechanism of a master mold for plastic products when the mask of the mold has barbs and no large broken surface. 【Background technique】 [0002] The traditional oblique pin return structure of the master mold, such as figure 1 As shown, when the mold is opened, the male mold core 14 moves downward, the spring 11 releases the pressure and pushes the thimble pin 12, and then the inclined pin 13 moves downward, forcing the product 15 to leave the female mold core 16; when the mold is closed, the male mold core 14 will be inclined Pin 13 is pressed back and moves up. [0003] For the return structure of the oblique pin of the above-mentioned female mold, because it must correspond to the direction of the oblique pin 13, select the corresponding spring 11, and set the through hole on the female template for the movement of the spring 11, and ...
