Specific embodiment
It is described in detail below in conjunction with embodiment of the attached drawing to technical solution of the present invention.Following embodiment is only used for
Clearly illustrate technical solution of the present invention, therefore be only used as example, and cannot be used as a limitation and limit protection model of the invention
It encloses.
As shown in Figures 1 to 4, vacuum absorption holes straight forming device 100 provided in this embodiment, including：It is arranged preceding
Several groups adsorption hole shaping mechanism 20 in template 10, every group of adsorption hole shaping mechanism 20 include：Sleeve 21, the hand-manipulating of needle 23, sliding block
Seat 25 and oil cylinder 26.
Referring to Fig. 1, for individual one group of adsorption hole shaping mechanism 20, sleeve 21 is provided with several in front template 10
A, the front end of sleeve 21 is exposed to the forming surface of 10 die cavity of front template and corresponding with 201 position of the adsorption hole of moulding 200, often
Multiple adsorption holes 201 in a region, multiple groups adsorption hole shaping mechanism 20 on the corresponding moulding 200 of group adsorption hole shaping mechanism 20
The different location of moulding 200 is set to cover all adsorption holes 201 on moulding 200；The butt of sleeve 21 extends to
In the shaping mechanism installation cavity 11 opened up on front template 10, shaping mechanism installation cavity is fixed to especially by the press fitting of sleeve pressing plate 22
11；The step-like axis hole of setting in sleeve 21, the diameter of the axis hole of front end is 1.4mm, radially suitable with the hole with adsorption hole 201
It answers, it is specially 8mm in the present embodiment that the diameter of the axis hole of butt, which is greater than 1.4mm, larger greatly in outer dimension to meet depth drill
Mold on minimum process aperture.
The hand-manipulating of needle 23 and sleeve 21 are plugged in correspondingly in the axis hole of sleeve 21, and suitable in the axis hole sliding in sleeve 21
The front end of the step shaft-like matched, the hand-manipulating of needle 23 is adapted with the axis hole of 21 point diameter 1.4mm of sleeve, so that it can be in axis hole inner shaft
The front end for protruding from sleeve 21 to sliding enters in die cavity, to carry out the forming operation of adsorption hole 201 to moulding 200.Row
The butt fixation of needle 23 is connected on take-up housing 25, specifically, the length of the hand-manipulating of needle 23 is longer than sleeve 21, the butt of the hand-manipulating of needle 23 passes through set
It is abutted on take-up housing 25 after the hand-manipulating of needle hole being arranged on cylinder pressing plate 22, take-up housing 25 is set to the shaping mechanism on front template 10
In installation cavity 11, a hand-manipulating of needle pressing plate 24, the hand-manipulating of needle 23 is arranged in the one side of the bottom towards shaping mechanism installation cavity 11 of take-up housing 25
It is fixed on take-up housing 25 by the press fitting of hand-manipulating of needle pressing plate 24.A mounting plate 27, oil is arranged in the open end of shaping mechanism installation cavity 11
Cylinder 26 is installed on mounting plate 27, and the piston rod of oil cylinder 26 is connect by connecting rod 28 with take-up housing 25, to drive sliding block along row
Needle 23 slides axially.
It because the point diameter of the hand-manipulating of needle 23 only has minimum 1.4mm, easily damages, disassembling, assembling and replacing and molding die sinking in mold
During, stores the retraction of the hand-manipulating of needle 23 in sleeve 21 by the contraction of oil cylinder 26, avoid touching in it and along bad；After molding
When injecting molten plastic into die cavity, then by the ejection hand-manipulating of needle 23 of oil cylinder 26, to carry out vacuum suction to the moulding 200 in die cavity
The molding in attached hole 201, the safety of the whole process protection hand-manipulating of needle 23 and entire adsorption hole shaping mechanism 20, improves the service life of mold.
Vacuum absorption holes straight forming device 100 by adopting the above technical scheme passes through sleeve 21 plus the suit of the hand-manipulating of needle 23
Composite structure, the hand-manipulating of needle 23 and depth drill processingHole solves the processing of aperture on mold by 21 transition fit of sleeve
Problem enables the device of moulding 200 (coating member) and 201 single injection-molded of vacuum absorption holes thereon, make product table as
Unified, stabilized product quality reduces after-processing technology, shortens the process flow of production, improving production efficiency；It is not necessarily to simultaneously
Secondary operation avoids reducing cost because of fraction defective caused by carrying, processing fault in post-processing.
It should be noted that preferred embodiment above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent
Present invention has been described in detail with reference to the aforementioned embodiments for pipe, those skilled in the art should understand that：It is still
Can modify to technical solution documented by previous embodiment, or some or all of the technical features are carried out etc.
With replacement；And these are modified or replaceed, technical solution of the embodiment of the present invention that it does not separate the essence of the corresponding technical solution
Range should all cover within the scope of the claims and the description of the invention.
