Embodiment Construction

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

[0016] Such as Figures 1 to 2 The anti-garbage structure of a plastic mold thimble plate is characterized in that it includes a movable mold bottom plate 1, an ejector pin bottom plate 2 is connected to the movable mold bottom plate 1, and the thimble bottom plate 1 is in contact with the movable mold bottom plate 1. One side is provided with a small block assembly 3 with the same height and can make the force between the ejector pin bottom plate 2 and the movable mold bottom plate 1 uniform, and the ejector pin bottom plate 2 and the movable mold bottom plate 1 between the small block assemblies 3 form a garbage trough 4.

[0017] The small block assembly 3 of the present invention includes edge small block groups 31 arranged at intervals along the length direction of the thimble bottom plate 2 on the left and right sides, and the edge...

Abstract

The invention discloses a thimble plate garbage-proof structure of a plastic mould, and the thimble plate garbage-proof structure is characterized by comprising a movable mould bottom plate, wherein the movable mould bottom plate is connected with a thimble bottom plate; one face, which is contacted with the movable mould bottom plate, of the thimble bottom plate is provided with a plurality of small square block assemblies which have the same height and enable the stress between the thimble bottom plate and the movable mould bottom plate to be uniform; and a garbage groove is formed between the thimble bottom plate and the movable mould bottom plate between the small square block assemblies. Aiming to overcome the defects of the prior art, the invention provides the thimble plate garbage-proof structure of the plastic mould, and the thimble plate garbage-proof structure is simple in structure and convenient to machine.

Description

technical field [0001] The invention relates to an anti-garbage structure of a plastic mold ejector plate. Background technique [0002] In the existing plastic molds, when it comes to the anti-garbage structure of the ejector plate of the mold, the method used is to add about 5mm round garbage nails between the ejector base plate and the movable mold base plate to separate the two plates and create a gap. Allow small debris to leave the mold from between the gaps. This method is cumbersome to process. It is necessary to process screw holes on the bottom plate of the movable mold, and to process garbage nails on a lathe, to process screw countersunk heads, and to grind the garbage nails to the same height. When arranging the garbage pins, it is also necessary to consider not to interfere with other parts, and the garbage pins must be evenly arranged, otherwise the ejector pin plate will be deformed. Contents of the invention [0003] The purpose of the present invention ...
