Description

Ethylene-vinyl acetate resin object beveled structure

The utility model relates to a kind of beveled structure that is applied in the object that ethylene-vinyl acetate resin material makes.

Ethylene-vinyl acetate resin (hereinafter to be referred as EVA) is an a kind of foam sponge body, because the moderate attribute of its soft durometer adds its color diversification, applied to the laying on the floor in recent years widely, except can promoting indoor abundant colors, also can be prevented when children from falling injured.EVA not only can be applicable to the laying on the floor, and stationery ornaments etc. all can be applied, and the utility model mainly are the beveled structure of the made object of EVA such as.

As shown in Figure 1, the knuckle position of traditional E VA object 10, be after tailoring two corresponding tablets 11 in advance, again after the end face of two tablets 11 is smeared viscose glue, contraposition is bonding in addition to assemble, but this kind beveled structure former separation of two respective material and be difficult for accurate contraposition combination in assembling process, production efficiency is very low; Moreover the gluing process also needs the corresponding position of two separation is distinguished gluing respectively once, and note even coating, what of also wayward glue amount, in case the glue amount is too much, the glue situation of overflowing will have a strong impact on the quality of production, if when gluing is not enough, it is bad to add contraposition again, cause seam crossing to form the space, make product uneven, the easier situation that is difficult to fit and comes off that causes.

For another shown in Figure 2, the beveled structure of another kind of EVA object 10, also tailor two corresponding tablets 11 in advance, corresponding tenon 12 and caulking groove 13 are set in the end of two tablets 11, giving joggle after tenon 12 and caulking groove 13 are smeared viscose glue is bonded, though it saves cost, but because outside the knuckle seam crossing of EVA object is easy to be revealed in, influence that it is attractive in appearance, and if the control of viscose glue applying amount not good, add owing to cut form to form extremely many angles bent angle, gluing very difficulty is slow, and extremely difficult control glue amount uniformity and popularization, cause the end product quality of EVA object 10 low, reduce its commodity competitiveness.

Owing to EVA produces expansion by calorifying mould in foaming process, controls such as the shape size of EVA semi-finished product raw material and material density are difficulty quite, it is quite expensive to add mould, thereby all cut sheet usually with the moulding of full wafer rectangular body, get again thereafter cut sheet desire ask size and thickness to cut type, gluing, applying supervisor separately, according to the design of individual product with need implement processing, this is the main cause of the above-mentioned traditional EVA object of restriction at beveled structure.As adopt the mould foaming integrally formed, then the mould expense certainly will improve whole cost.

The purpose of this utility model provide a kind of simple in structure, make product quality height, ethylene-vinyl acetate resin object beveled structure that cost is low.

For reaching above-mentioned purpose, the utility model by the following technical solutions:

The utility model is that the fluting that is a suitable angle is offered at the position of amounting in advance on the EVA object, behind the coating viscose glue, is amounted in fluting, and two adjacent surfaces of fluting are bonded as one.This kind EVA object beveled structure during fabrication, amount to face adjacent two, need not carry out contraposition, exist and there is no seam in appearance, and in the process of gluing coating, can accurately finish gluing work simply rapidly with smooth-going direction uniformly, except can improving working (machining) efficiency and structural strength, finished product also have aesthetic feeling in appearance, can strengthen commercial competitiveness.

The utility model will be further described below in conjunction with drawings and Examples:

10 for the EVA object, 11 for tablet, 12 for tenon, 13 for caulking groove, 14 for flakes, 15 for fluting, 16 be that first composition surface, 17 is second composition surface.

At first as shown in Figure 3, the utility model is to offer fluting 15 in the position that the tablet 11 of EVA object 10 is amounted in advance, fluting 15 is divided into two flakes 14 with this tablet 11 neighbours, this fluting 15 is made of two adjacent first composition surface 16 and second composition surfaces 17, two composition surfaces 16, has a suitable angle between 17, wherein composition surface 16 in fluting 15, after being coated with viscose glue on 17 or two composition surfaces, amounted to, can make two composition surfaces 16 of fluting 15,17 are bonded as one, make this tablet 14 amount to as shown in Figure 4 EVA object 10 finished products easily.

Cooperate shown in Figure 6 in addition by Fig. 5, when the utility model is applied to the manufacturing of EVA object,, can't utilizes fluting 15 to amount to fully and finish finished product if EVA object 10 has complicated external form, still can by the setting of tenon 12 and caulking groove 13 with cooperate, finish assembling; Have preferable aesthetic feeling for trying to achieve EVA object 10, the back side, rear or more unshowy part that the junction of tenon 12 and caulking groove 13 should be arranged at EVA object 10 are good.

The angle on two composition surfaces 16,17 of fluting 15 of the present utility model is to decide on the angle of EVA object 10 finished product knuckles, and the formula of its application is: the angle angle on EVA object finished product knuckle angle=180 degree-two composition surfaces; For example, the angle of EVA object 10 finished product knuckles is 90 degree, and then the angle of two joint fasteners 16,17 is 90 degree, and other supposes that the angle of EVA object 10 finished product knuckles is 120 degree, and then the angle on two composition surfaces 16,17 is 60 degree.

Fig. 4 and shown in Figure 6 for another example, the utility model finish amount to assembling after, there is no seam produces in the outer face of amounting to the position, and suitable fillet is slided in formation one naturally, can make the knuckle quality of EVA object 10 finished products improve, simultaneously outward appearance has more aesthetic feeling, and the structural strength height can improve the commodity competitiveness of EVA object 10.

In addition, offering of the utility model fluting 15, after only must milling by cutter, promptly plastic, its cost is quite cheap, and can be according to the specification and the type shape of EVA object 10, flexible utilization, and it offers the angle of fluting 15, the cutter that only need select suitable angle for use is convertible fluting angle, the clearance distance of fluting and length also can need according to the specification of product arbitrarily to adjust to change.

In addition as shown in Figures 7 and 8, the two sides angle is adjusted on equidistant plane, after knuckle, can be formed sliding cylinder along circular shape, smooth in appearance mellow and full, can not be out of shape.

Fig. 9 and shown in Figure 10 and for example, according to the applied mode of knuckle characteristic of the present utility model, can do a suitable correction according to product, the notepad shown in the figure, its knuckle position need not fixed, therefore, fluting in 15 first composition surface 16 and second composition surface 17 on do not need glue bond, utilize the characteristic of EVA high tenacity, can make this fluting 15 have function as hinge, this fluting 15 seems that through the outer face behind the knuckle very natural cunning is suitable.
