Abstract
The invention discloses an application of sleeving and stretching molding technology in shoe molding or injection production. The application comprises steps that, (1), the upper sleeving molding technology is applied to molding or glue injection; (2), alignment and lock stitch for insole periphery and upper bottom edges are carried out, sleeving molding in a shoe is carried out, front tip lasting molding is carried out, and de-molding is carried out to realize bonding of the upper and the shoe sole; and (3), the technology flow comprises lock stitch, upper sleeving, toe lasting, fluffing, sand covering, processing agent brushing, glue brushing, drying and injection molding and mold unloading. Through the application, upper margins are only 5-6mm, and raw materials are greatly saved.
Description
Technical field
The invention belongs to technical field of shoe making, relate in particular to a kind of cover, the application of moulding process in mold pressing or injection shoes are produced of stretching tight.
Background technology
Tradition stretches tight the technological process of shoe last or hat block moulding pressing (injection) footwear: machine stretch tight point ~ dropping place ~ thorn limit ~ brush flank glue ~ craft stretch tight waist ~ machine stretch tight with ~ fluffing ~ multiple sand ~ brush inorganic agent ~ brush waist side glue, oven dry ~ mold pressing (injection) shaping ~ depanning ~ modification.Its side pin pressure inner bottom width 12 ~ 15mm, waste raw material.
Summary of the invention
The object of the invention is to overcome that above-mentioned deficiency provides a kind of cover, the application of moulding process in mold pressing or injection shoes are produced of stretching tight.Step is that (1) upper of a shoe cover side moulding process is applied at mold pressing (injecting glue) footwear.(2) this patented technology is middle bottom perimeter and upper of a shoe base contraposition eyelet, and shoe lining cover side is shaping, and the paracone shoe last or hat block that stretches tight is shaping, then just goes mold pressing (injection) to complete the bonding helped at the end.(3) this kind of patent technology flow process: eyelet ~ cover side ~ machine stretch tight point ~ fluffing ~ multiple sand ~ brush inorganic agent ~ brush coating, oven dry ~ mold pressing (injection) shaping ~ depanning.The present invention helps pin nargin to only have 5 ~ 6mm, greatly saves raw material.
For achieving the above object, the present invention is by the following technical solutions:
Cover, the application of moulding process in mold pressing or injection shoes are produced of stretching tight, comprise the following steps:
A eyelet: in the middle end and toe lasting, rear side (face, inner) end mouth mark slits contraposition, and apart from limit 4 ~ 5mm, eyelet pin code size is 7 ± 1 pins/20mm, should evenly put in place.Inaccurate off-line, broken string etc., play non-return seam 3-4 pin.
B overlaps shoe last or hat block: shoe tree side number conforms to, and be inserted in upper of a shoe cover, front and back put in place, and the symbol that just stretches tight of stretching tight stretches tight flat, meets the requirements.
C brush dress toe box: front upper is opened, and brush coating pastes toe box, should put in place, rectify, paste symbol.
D machine stretches tight point: the paracone upper toe laster symbol that stretches tight just stretches tight, and side pin cements, sticky flat, and semi-finished product length meets the requirements.
E thermal finalization: enter the large case of heat and dry.Temperature 120 ~ 135 DEG C, 15 ~ 20 minutes time, till parching.
F fluffing, multiple sand: according to mold pressing (note pressure) position fluffing, multiple sand, lint pull-up, the degree of depth is no more than the 1/4-1/3 of leather thicknesses.
G brush inorganic agent: side pin brush inorganic agent is also dried, temperature 45 ~ 55 DEG C, 4 ~ 6 minutes time.
H brush coating, oven dry: brush coating two road is also dried, temperature 55 ~ 65 DEG C, 5 ~ 8 minutes time.
I mold pressing (injection): temperature 155 ± 5 DEG C, 15 ± 2 minutes time, pressure 7 ~ 12bra.Inaccurate deficient sulphur, over cure, bloom etc.
J depanning: in required time, temperature, pressure, completes the side shaping rear depanning in the end.
Adopt technique scheme, the present invention has following advantage:
The invention discloses (1) upper of a shoe cover side moulding process to apply at mold pressing (injecting glue) footwear.(2) this patented technology is middle bottom perimeter and upper of a shoe base contraposition eyelet, and shoe lining cover side is shaping, and the paracone shoe last or hat block that stretches tight is shaping, then just goes mold pressing (injection) to complete the bonding helped at the end.(3) this kind of patent technology flow process: eyelet ~ cover side ~ machine stretch tight point ~ fluffing ~ multiple sand ~ brush inorganic agent ~ brush coating, oven dry ~ mold pressing (injection) shaping ~ depanning.Tradition side pin pressure inner bottom width 12 ~ 15mm, and this patent technological requirement side pin nargin only has 5 ~ 6mm, greatly saves raw material.
