Embodiment Construction
[0037] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0038] Such as figure 1 As shown, the ejection mechanism is the prior art, wherein one end of the push tube 212 is nested in the male mold 130, and the end of the push tube 212 is exposed outside the male mold 130, and the other end of the push tube 212 is connected to the top plate 221 connected, through the up and down movement of the top plate 221, the up and down movement of the push tube 212 is realized, that is, the stroke of the top plate 221 is equal to the stroke of the push tube 212, and the stroke is relatively long, generally around 28mm, so that the manufacturing cost of the ejector mechanism , manufacturing difficulty increases; slide block 320 is slid on one side of male mold 130 by spring, when clamping mol...

The invention provides an anti-interference ejection mechanism which comprises a bracket, an ejection assembly and a sliding assembly, wherein one end of the ejection assembly is embedded into the bracket, and the other end of the ejection assembly is connected with the bracket; and one end of the sliding assembly is connected to one side of the bracket in a sliding manner, and the other end of the sliding assembly is a free end. According to the anti-interference ejection mechanism provided by the invention, at a die assembling or opening state, the ejection assembly nested at one end of the bracket is always located in the bracket without being exposed out of the bracket, so that the condition that when the sliding assembly moves, the free end of the sliding assembly collides with the ejection assembly is avoided, and further the safety of the ejection mechanism is improved; and furthermore, damage to a die is prevented, and the service life of the ejection mechanism is prolonged.
Description
technical field [0001] The invention belongs to the technical field of machinery, and relates to an ejection mechanism, in particular to an anti-interference ejection mechanism. Background technique [0002] Traditional hot-melt column ejection mechanism, such as figure 1 As shown, the ejection stroke of the push tube in this mechanism is relatively large, and the larger stroke means that the size of the matching section between the push tube, the inner needle of the push tube and the male die is longer, so that the manufacturing and installation accuracy of the push tube requires High, and the push tube is prone to jamming during the ejection process, causing damage to the push tube, which not only increases the manufacturing cost of the ejector mechanism, but also increases the difficulty of manufacturing the ejector mechanism. In addition, there is a slide on the side of the push tube Block assembly, when the mold is closed, the slider will move towards the direction of ...
