Description

For the mold cavity of leather and plastic cement adhesive bond
Technical field
The utility model relates to industrial processing equipment technical field, be specifically related to a kind of for leather and plastic cement adhesive bond device.
Background technology
Leather is for consumption electronic product, and dimension precision requirement is higher, the combination of leather and plastic cement in conventional art, usually adopts the technique that glue is bonding.Due to the uncertainty of material, technique, cause the fraction defective of finished product high, dimensional accuracy is low, poor reliability, and production efficiency is low.Specifically, the supplied materials thickness of leather itself can directly affect dimensional uniformity during flange bound edge, the leather tolerance of such as 0.5 is ± 0.1. this can cause gap or extension limit to the assembling cooperation of high-quality requirement.The inhomogeneities of the thickness of leather own also can be displayed after viscose glue, even if all thick leather of supplied materials may occur rough phenomenon equally after viscose glue.The poor reliability of viscose glue, even if strictly control technique, under the condition of high humidity, leather occurs that the possibility of bubble is very high.And glue complex process, often need to adopt at leather and plastic cement is two-sided carries out silk-screen glue, then fit, heat bound edge again, trivial operations, efficiency is low.In addition, the general inadequate environmental protection of glue, smell is obvious, can affect workman healthy, and bonding after need place certain hour could use, have impact to production waiting, cause production efficiency low.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of reasonable in design, production efficiency are high, the mold cavity for leather and plastic cement adhesive bond of the good product quality produced.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of mold cavity for leather and plastic cement adhesive bond, it is characterized in that: comprise for the shaping front mould of leather and the rear mold for plastic rubber shaping, front mould have indent for placing die cavity (beer mold cavity) before leather, front mould medial surface is provided with the main locating slot for locating with rear mold, and main locating slot is positioned at front die cavity side; Rear mold has the shaping boss matched with front mold cavity shapes, and have in the middle of shaping boss and hold material die cavity, rear mold medial surface is provided with the main positioning table that position and size and main locating slot match; There is between leather and the shaping boss of rear mold under front mould and rear mold matched moulds state the die cavity for plastic rubber shaping; Charging aperture is between front mould and rear mold, and diving mouth is positioned at rear mold.
Further, described front mould inner cavity surface has erosion leather lines.
Further, also comprise and expect that die cavity matches with appearance and also can be contained in the support of expecting in die cavity.
Further, described front mould medial surface is provided with the some sides locating slot for auxiliary positioning, and rear mold medial surface is provided with the side positioning table that position and size and side locating slot match.
Technological process: the first step, tiled by leather, cut into rectangle with cutter, size exceeds front die cavity edges 15-20mm;
Second step, puts into front die cavity location by leather, then matched moulds locking, and the pressing amount of leather must not damage leather;
3rd step, injects ABS plastic, sizing shaped, cooling;
4th step, mold pickup;
5th step, the shaping rear bound edge of cover beer, cutting tool trimming.
The utility model, by leather being put into the mold cavity of intended size, is moulded in process at beer, and leather fits to mold cavity under injection pressure effect; Shaping size and outward appearance are determined by die cavity, do not affect by supplied materials, fundamentally can solve size instability and the irregular problem of outward appearance; Plastic cement is combined with leather closely, and beer is moulded in process can not have air trapping, and through environmental testing and high humility test (100%RH, 6H), leather there will not be bubble; Man-hour reduces to 22 stations from 32 stations of artificial lagging, saves artificial 1/3rd.Because beer moulds size accurately, control stable and uniform with miscellaneous part fit clearance, production efficiency significantly improves.Decrease to the requirement of supplied materials leather thicknesses, leather yields rises, and reduces cost.
