Abstract

The invention discloses processes and products of double-material injected or thermally-welded hooks, and discloses four different double-material injection or thermal welding methods as follows: a double color mould method, two kinds of package plastic mould methods and a thermal welding method. The products prepared by the four methods are mainly composed of a suction pad and a hook support, the suction pad and the hook support are not in UV glued connection, but are connected integrally firmly by the four processes, the hook support comprises a pressing strip, hook holes and a reinforcing rib hole; the reinforcing rib hole comprises a plurality of countersunk head interlaced holes, criss-cross rib grooves, a plurality of small holes, and the like, and by the role of the pressing strip, the hook hole and the reinforcing rib hole, the suction pad and the hook support are integrally connected much firmly. Two ends of the hook penetrate the hook holes, when an object is hung up, the pressing strip is pressed, the pressing strip bears part of gravity component and presses (namely, seals) the suction pad, so that, when a heavy object is hung up, the persistence of the hook is improved greatly.

Description

The technique of double-material injection-molding or heat seal welding hook and product

Technical field

The present invention relates to the technical field of commodity hook product, refer in particular to technique and the product of a kind of double-material injection-molding or heat seal welding hook.

Background technology

At present, market there is a kind of Traceless hook, use UV glue, through Ultraviolet radiation, sticker (inhale and paste) and hook bearing are bonded together, all good than traditional hook with sucker in anti-slip and heavy burden, but, UV glue and the sticker price eighteenth of the twenty expensive, directly cause the sharply rising of this Traceless hook cost, present invention uses different manufacturing process to obtain the hook of this cheapness.Moreover UV glue Traceless hook is hung the weight time and has been grown, and can cause aging coming off.Process of the present invention, sticker and hook bearing are close to body and are connected (such as: sticker soft pvc, hook bearing hard PVC, the connection of same material body), and the steadiness of long-term load-bearing is improved greatly.

Summary of the invention

The hook with sucker Technical comparing that the present invention is close with another: traditional movable hook is arranged on supercharging and covers, after using a period of time, the supercharging portion of covering slowly departs to inhale pastes, lose inhaling " supercharging " effect of pasting, and produce a kind of with inhale veneer harmful power of pullling at angle and pull to inhale and paste, make air easily invade to cause and come off.Linking up with optimal Impact direction is press close to and be parallel to suction veneer, and the present invention stressedly to conceive according to hook is optimal.Traditional hook with sucker, together with hook bearing to be included in sucker by 6 of periphery or 8 intertexture holes, hook bearing and sucker be do not glue dead, in other words, if without intertexture hole, hook bearing can rotate in sucker, can also firmly take out from sucker, just look like that hook bearing connects the class that threaded rod is metal, can not bond together, Here it is usually said " false double-colored " mould, sucker is disk-like structure mostly, these traditional structures, are doomed to hang weight for a long time.Suction of the present invention is pasted and is recommended by plane structure, and it is extremely be connected the one of a piece as sticky with UV glue that hook bearing and inhaling pastes, or even the body connection of the different same material double-material injection-molding of use soft or hard, Here it is usually said " very double-colored " mould.

The object of the invention is to overcome the weak point of current UV glue Traceless hook and the technological deficiency of conventional suction cups hook, provide a kind of structure simple, the product technology scheme of handling ease.

I has done following test with nearly year on common smooth ceramic tile:

Test 1, uses diameter 70mm, and film commodity hook inhaled by the UV glue that heavy 4Kg is hung in nominal, hangs up the weight of 2.5Kg, less than 2 months, inhales that film is wrinkling to come off.

Test 2, uses the PVC film of the thick 90mm pros of 0.4mm, and hook rest base coats UV glue, is bonded on transparent PVC cushion compound, with low-power UV light irradiation 15 minutes, after one day, hang up 3Kg chopping block, after 4 months, inhale film and slowly start wrinkling, after 6 months, chopping block drops.Visible by test 1,2, inhaling film hook can not hang weight.

Test 3, use the PVC film of the thick 90mm pros of 1.5mm, hook bearing (hard PVC material) bottom and this film heat seal weld together, and hang up the weight of 5.3Kg, till being suspended to writing this description from last Nov 10, although there is free gas cut to enter, but also do not come off, show the extension Beijing South Maxpower Technology Co. Ltd power that this hook is superpower, if hang the weight of 1 or 2Kg, perhaps can hang 2 to 3 years, foot is in the needs of the most daily living article of satisfied extension; If the air bag that it is 201320031211.2 again with the patent No. combines, the air invaded is gulped down to air bag, the time of hanging weight can be extended again greatly.

According to test above, present invention employs following four kinds of double-material injection-moldings or heat seal welding procedure design:

First kind of way, with double-color mold, on a double coloured plastic injection machine, shaping at twice, but a depanning, a set of double color mould comprises two cover injection molds, two molds share a set of clamping apparatus, and the dynamic model of this two mold is the same, and cover half is then not identical, first inject hook bearing with hard material, only eject running channel, hook bearing is then retained in dynamic model, dynamic model revolves turnback, close die, carries out second time injection moulding and inhales subsides, die sinking afterwards, ejects or takes out finished product; Injection is inhaled the temperature of pasting and is advisable than low 60 degree of the temperature of injection hook bearing.

The second way, with encapsulation die, hook bearing and suction are pasted and are not necessarily completed on an injection machine, and shaping at twice, have two molds, first set first injects hook bearing, then it is put into the second cover die, inject together with pasting with suction; The temperature (such as low 20 degree than the fusing point of hook bearing) of pasting is inhaled in adjustment injection, and just make and link up with bearing composition surface and melt, if desired, the hook bearing first injected carries out preheating, can be melt together and be advisable both adjusting to.

The third mode, with encapsulation die, first set first injects to inhale and to paste or punching goes out signature and moulds to inhale and paste, then it is put into the rear mold of the second cover die, injects together with hook bearing; The temperature of adjustment injection hook bearing, just makes to paste composition surface and melt with inhaling, if desired, first cooling is pasted in suction, or the fortune water strengthening mould reduces the rear mold temperature of inhaling and pasting side, both adjusting to, composition surfaces can be melt together and be advisable, and this is that (Normal practice is that first injection moulding is expected firmly to a kind of anti-convention way, the soft material of rear injection moulding), but, as pasted with giving as security the suction of moulding, smooth not warpage, this is to the vital performance of hook, and it is slightly inferior that subsides are inhaled in injection moulding.

Second and third kind of mode, note the fusing point of bi-material, if first time injection moulding or to give as security plastics fusing points too high, namely the material temperature degree injected for the second time is on the low side, so, this material of twice can not molten adhere well, and faying face intensity will be had a greatly reduced quality or cannot be welded together at all.If first time injection moulding or to give as security plastics fusing points too low, i.e. the material temperature drift that injects of second time, so, primary material will be melted away, can not be welded together, so, the temperature of the material that second time injects will want close or identical with the fusing point of primary material, could molten adhere.

4th kind of mode, uses heat seal welding procedure, inhales and pastes and hook bearing, welded together by heat seal bonding machine (such as using high frequency heat-sealing machine) heat seal.This mode also will notice that the fusing point of bi-material wants identical or close.

Double-material injection-molding or heat seal welding will note the blending (as selecting hard PVC and soft pvc, hard ABS and soft pvc, hard ABS and soft TPE, hard ABS and soft TPR) of these two kinds of soft or hard materials, not all material can affinity fusion together.

The double-material injection-molding produced according to four kinds of double-material injection-moldings above or heat seal welding procedure design or heat seal welding hook product paste primarily of suction and hook bearing composition, hook bearing pastes with suction the one side bonded and is distributed with reinforcement hole, and both use double-material injection-molding or heat seal welding procedure to carry out one connection.

Described hook bearing comprises compression bar, hook hole and reinforcement hole; Reinforcement hole comprises several countersunk head intertexture hole, muscle groove and several apertures etc., hook bearing pastes with suction the one side bonded and comprises crisscross muscle groove, is distributed with several countersunk head intertexture hole and several aperture in hook bearing, and their effect is connected for pasting more firmly one at the bottom of hook bearing with suction; Hook two ends penetrate hook hole, when it hangs up object, push down compression bar, and compression bar is born the component of a part of gravity and compressed suction subsides, in order to increase the sealing effectiveness inhaled and paste.

Use such scheme, technique is simple, with low cost, manufacture craft does not use expensive UV glue and sticker, produces good benefit, and the persistence that hook hangs weight is improved greatly.
