Problems solved by technology
[0002] Due to the defects in the design of the existing puncture structure, it is easy to produce burrs at the puncture position of the hole during injection molding of the mold
After the product is injection molded, personnel must be arranged to remove the burrs, which will increase the labor cost accordingly. Manual processing cannot guarantee the diameter of the hole.
The existing front mold pins and back mold pins cannot be effectively pressed after being penetrated, and they will deviate during the production process, resulting in burrs in the holes

Embodiment Construction
[0016] The present invention will be further described below in conjunction with accompanying drawing description and specific embodiment:
[0017] Such as Figures 1 to 2 A kind of small hole puncture position structure for the mold is shown, including the back mold insert 2 arranged in the back mold 1 and the front mold insert 4 arranged on the front mold 3, in the said back mold insert Part 2 is provided with a rear mold insert 5, and one end of the rear mold insert 5 is provided with a puncture position 6, and a front mold insert 7 is provided in the front mold insert 4, and a front mold insert 7 is arranged on the front mold insert 4. One end of the insert 4 is provided with a compression mechanism 8 that can make the end of the front mold insert pin 7 be compressed in the puncture position 6 when the front mold 3 and the rear mold 1 are closed.
[0018] The penetration position 6 in the present invention can be an outer convex groove, and the end of the front mold inser...

The invention discloses a small-bore collision penetrating structure for a mould. The small-bore collision penetrating structure is characterized by comprising a rear mould insert which is arranged in a rear mould and a front mould insert which is arranged on a front mould, wherein a rear mould insert needle is arranged in the rear mould insert; a collision penetrating position is formed in one end of the rear mould insert needle; a front mould insert needle is arranged in the front mould insert; a pressing mechanism which is used for pressing the end part of the front mould insert needle into the collision penetrating position when the front mould and the rear mould are closed is arranged at one end of the front mould insert. In order to overcome the defects in the prior art, the invention provides the small-bore collision penetrating structure for the mould, which is simple in structure, convenient to mount, capable of effectively pressing the front mould insert needle and the rear mould insert needle after collision penetrating and capable of effectively avoiding formation of in-pore burrs.
Description
technical field [0001] The invention relates to a small hole puncture position structure for a mould. Background technique [0002] Due to defects in the design of the existing puncture structure, burrs are easily generated at the puncture position of the hole during injection molding of the mold. After the product is injection molded, personnel must be arranged to remove the burrs, which increases labor costs accordingly, and manual processing cannot guarantee the diameter of the hole. The existing front-mold insert pins and back-mold insert pins cannot be effectively pressed after being pierced, and will deviate during the production process, resulting in burrs in the holes. [0003] Therefore, the existing pinhole structure for the mold needs to be further improved. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a simple structure, easy installation, the front mold insert pin and the...
