Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing description and specific embodiment:

[0016] Such as figure 1 The illustrated anti-seize mechanism for the toss in the ejector plate includes a guide post 1 arranged on the ejector plate of the mold and a guide sleeve 2 arranged in the mold, and one side of the guide sleeve 2 is provided with a function to prevent the guide pin from The column 1 expands when heated and is stuck in the outer offset part 3 inside the guide sleeve 2 .

[0017] In the present invention, the distance between the inner wall of the outer offset part 3 and the outer wall of the guide post 1 is 0.2-0.5 mm.

[0018] In the present invention, the two end surfaces of the outer offset part 3 and the center of the enclosed guide post 1 form an included angle of 45°.

[0019] In the present invention, an elastic constant pressure column device 4 is provided inside the guide column 1 , and one end of the e...

Abstract

The invention discloses an anti-jamming mechanism for a shoulder guide bush in an ejector plate. The anti-jamming mechanism comprises a guiding column arranged on the ejecting plate of a mold and a guiding sleeve arranged in the mold. The anti-jamming mechanism is characterized in that an outer offset part capable of preventing the guiding column from being heated, expanded and accordingly jammed in the guiding sleeve is arranged on one side of the guiding sleeve. By the adoption of the anti-jamming mechanism, the defects in the prior art are overcome, and the anti-jamming mechanism for the shoulder guide bush in the ejector plate is simple in structure and capable of effectively preventing jamming.

Description

technical field [0001] The invention relates to an anti-jamming mechanism of a support in a thimble plate. Background technique [0002] The temperature of the mold will rise slowly during the production process, and the mold will thermally expand after the temperature rises. Due to the design defect of the supporting mechanism in the existing ejector plate, the situation of jamming often occurs. [0003] Therefore, the supporting mechanism in the existing ejector plate needs to be further improved. Contents of the invention [0004] The object of the present invention is to overcome the disadvantages of the prior art, and provide a simple structure, which can effectively prevent jamming of the thimble plate in the torso anti-jamming mechanism. [0005] In order to achieve the above object, the present invention adopts the following scheme: [0006] An anti-seize mechanism for the toss in the ejector plate, comprising a guide post arranged on the ejector plate of a mold ...
