BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a mold for manufacturing a mat, and more particularly, to a mold technique in which the concept of gravity is introduced into an injection molding so that a fusion-

Generally, mats are used in playrooms or homes to prevent children from getting hurt or interlayer noise. Such a mat is mainly composed of an internal filler made of a synthetic resin foamed molded body and a sheet member which is wrapped around the upper and lower surfaces of the filler.

The inner filling material uses a member having a cushioning function, and the sheet member is made of a structure in which the inner and outer portions are attached as a film. At this time, since the inner filling material has a size slightly smaller than that of the outer sheet member, a mat is formed in such a manner that the inner filling material is hermetically accommodated between the upper and lower sheet members. Here, the term " sealing " refers to a structure in which the sheet member on the upper surface and the sheet member on the lower surface are adhered to each other and the internal filler is received inside the edge portion.

In recent years, such a mat has also been demanded to be eco-friendly, so that it is being replaced with a synthetic resin foam molding method by a heat fusion method in a manufacturing method using a conventional adhesive. As a result of manufacturing by a press mold method, Lt; / RTI >

When the upper and lower surfaces of the respective members are simultaneously heated and fused to produce the upper and lower press molds, the physical properties of the entire mat member are disadvantageously reduced. As a result, when the product is pulled out from the horizontal mold and solidified, There is a problem that arises.

In order to solve this problem, for example, if the upper surface is first heated and fused, then turned over again and the lower surface is heated, the same operation is required to be carried out twice, resulting in remarkable decrease in productivity and simultaneous heating There is a problem that the quality of fusion bonding is lowered.

Also, in the conventional press mold, air is easily left between the inner filler and the sheet member, which is the outer shell, during the fusing process. Therefore, a process such as an air discharge pump is added to prevent this. However, in practice, there is a problem that it is difficult to completely discharge the air.

Therefore, there is a need to study a mold as a new mat manufacturing method.

1 to 3 are views showing a fusion mold for a mat using gravity according to a first embodiment of the present invention.

That is, the present invention provides a mat (1000) comprising an inner filler (1) having no cushioning property and a first sheet member (10) and a second sheet member (20) each wrapping the upper and lower surfaces of the inner filler ). ≪ / RTI >

1 to 3, a mat 1000 is manufactured with a pair of first outer circumferential surfaces 101 and a second outer circumferential surface 201 being in contact with each other while being perpendicular to the ground surface. To this end, the metal mold for matting includes a first rotatable mold body 100 and a second rotatable mold body 200, which rotate the first outer circumferential surface 101 and the second outer circumferential surface 201 in opposing directions, The first outer circumferential surface 101 is an outer circumferential surface of the first rotatable mold body 100 and the second outer circumferential surface 201 is an outer circumferential surface of the second rotatable mold body 200.

The first mat form frame 102 is formed on the first outer circumferential surface 101 and the second mat form mold 202 is formed on the second outer circumferential surface 201. The mat form frame 102 on the upper face part rotates in the forward direction while receiving the first sheet member 10 and the mat form frame 202 on the lower face part rotates in the opposite direction while receiving the second sheet member 20, The first filler member 1, the first sheet member 10 and the second sheet member 20 are combined while heating the internal filler 1 between the first filler member 10 and the second filler member 20, (1000) is generated. At this time, the above-described operation, that is, the mold generating operation is controlled through the mold control unit 300.

In other words, the mold control unit 300 includes an interlocking structure in which each member is fused and coupled to the mat 1000 under the control of the mold control unit 300 so as to solidify the mat 1000 in a downward direction perpendicular to the ground plane. In other words, the mat molds 102 and 202 are disposed in a plurality of pairs on the first outer circumferential surface 101 and the second outer circumferential surface 201, and the mold control unit 300 includes the first rotatable mold body 100 and the second mold The rotating mold body 200 rotates in synchronization with each other, and the rotation is controlled by using a gear or a servo motor. At this time, it is possible to automatically correct the synchronization error caused by the temperature, and to control the speed according to the type of the product. The first sheet member 10 and the second sheet member 20 are fused together through the fusing heating unit 300a and the first sheet member 10 and the second sheet member 20 The inner filler 1 is placed in the edge portion 30 which is in contact with and fused with each other to produce a mat 1000 that is coupled. At this time, the fusing heating section 300a is a high-frequency to far-infrared heating mechanism for heating the member about the inner filler 1 immediately before being received in the metal mold.

For the configuration in which the first sheet member 10, the second sheet member 20 and the inner filler 1 are accommodated, the fusion metal mold for a mat includes a first sheet member 10, a second sheet member 20, And member feed rollers 11 and 21 for feeding the mold 1 to the first mold body 100 and the second mold body 200. The mold control unit 300 includes the above- As a sequence. That is, in order to allow the first sheet member 10, the second sheet member 20 and the inner filler 1 to be injected from the top of the first rotatable mold body 100 and the second rotatable mold body 200 And the mat welding metal mold has a guide 1a and member feed rollers 11 and 21 and is provided with a first rotatable mold body 100 and a mat 1000 disposed at a lower portion of the second rotatable mold body 200 And accelerate the solidification through the cooling means 400. [0054]

More specifically, the respective components will be described as follows.

The internal filler 1 is a main material constituting the mat 1000, for example, a cushioning material. The first sheet member 10 is applied to the upper surface portion of the inner filler 1 and the second sheet member 20 is applied to the lower surface portion thereof. At this time, the inner filler 1 may be smaller in size than the first sheet member 10 and the second sheet member 20. Therefore, the edge portion 30, which is the edge portion, is fused with the first sheet member 10 and the second sheet member 20 in close contact with each other without the inner filler 1. [ That is, the mat 1000 is formed in a state in which the inner filler 1 is sealed in the edge portion 30, and the inner filler 1, the first sheet member 10, and the second sheet 10, Is formed by fusing the member (20).

That is, the present invention relates to a mold for manufacturing a mat (1000), which comprises a first rotating mold body (100) and a second rotating mold (100) centered on roller shafts (110, 210) horizontally installed on a ground base The mold body 200 rotates. That is, the pair of first outer circumferential surfaces 101 and the second outer circumferential surfaces 201 are opposed to each other and rotate in opposite directions. In other words, the outer circumferential surfaces 101 and 201 are engaged with each other so as to face each other so as to face each other. Thus, the inner filler 1, the first sheet member 10 and the second sheet member 10 are separated and inserted before being engaged with each other, The inner filler 1 is combined with the first sheet member 10 and the second sheet member 20 and drawn out to the mat 1000.

On the other hand, a plurality of the first mat form mold 102 and the second mat form mold 202 may be provided. That is, a plurality of first mat formers 102 may be formed on the first outer circumferential surface 101, and a plurality of second mat formers 202 may be formed on the second outer circumferential surface 201. Accordingly, the mats 1000 can be produced several times while the mold bodies 100 and 200 rotate one turn.

The mold control unit 300 rotates in the forward direction while the upper side of the mat form frame 102 receives the first sheet member 10 and the lower side of the mat form frame 202 is rotated by the second sheet member 20, And the sheet members 10 and 20 are fused at portions where the mat members 102 and 202 contact each other. That is, when the fusing heating part 300a is heated between the first sheet member 10 and the second sheet member 20 and the internal filler 1 is received, The mats 1000 to which the first sheet member 10 and the second sheet member 20 are combined are pulled out.

For this, the mold control unit 300 controls the first rotating mold body 100 and the second rotating mold body 200 to rotate in synchronism with each other. Furthermore, in order to more reliably control such a synchronous rotation, the mold control unit 300 can control the automatic correction of the synchronous switching state by a temperature sensor (not shown). The above-described synchronous control can be performed by using one power as the same gear ratio or by controlling each of the motors by using a servo motor. Particularly, when the rotational power of the mold bodies 100 and 200 is driven by a separate servomotor, by controlling the synchronous sensor and the temperature sensor to interlock with each other to correct a constant rotational speed and difference between them, It is possible to follow the phenomenon in which the mold is deformed, so that a precise product can be produced.

Also, the mold control unit 300 can arbitrarily set the rotational speed through the power control of the first rotatable mold body 100 and the second rotatable mold body 200. In this case, various products can be freely produced in accordance with the thickness, size, shape, partition structure, etc. of the member used, and versatility is secured.

The first sheet member 10, the second sheet member 20 and the inner filler 1 are continuously supplied at the upper end of the rotatable mold bodies 100 and 200 for efficient production of the mat 1000 For this purpose, it is necessary for the mold control unit 300 to control cutting to one product unit in the middle of the molding operation by continuously feeding the members. For example, the inner filler 1 is preferably introduced through a guide 1a in a unit of a predetermined interval, which is a unit prepared in advance, and the first sheet member 10 and the second sheet member 20 The mat 1000 is cut through the cutter 500 at the edge portion 30 between the one mat 1000 and the other mat 1000 in the lower portion of the mold body after being joined so that one product unit So that it is preferable to produce it. Of course, the guide 1a and the cutter 500 are not necessarily located at a specific place, but may be appropriately positioned according to design, and may be selected in various shapes. To this end, at least one roller 11, 21 and a cutter 500 are provided, and the mold control unit 300 controls at least one roller 11, 21 and the cutter 500 in sequence. At this time, the rollers 11 and 21 are members used to continuously feed the sheet member.

Meanwhile, through the above operation, the present invention has an advantage that deformation does not occur in the solidification process of the mat (1000). That is, when the upper and lower sheet members are simultaneously heated in a press die which presses in the vertical direction, the physical properties of the fused mat are disadvantageously degraded. When the sheet material is solidified in a horizontal plane, There was a problem that was easy to happen. However, in the case of the present invention, this problem is solved in principle while heating the upper and lower sheet members 10 and 20 at the same time.

That is, in the present invention, the mat 1000 drawn out from below the mold bodies 100 and 200 is vertically stretched and suspended by using gravity in reverse, so that the mat 1000 is straightened straight and straightened by the action of gravity . At this time, the solidification of the mat 1000 can be rapidly achieved through the cooling means 400 in order to further stabilize the molding operation and further increase the productivity of the product. In other words, the present invention can prevent the shape deformation after the respective members are joined by fusing to form the mat (1000), and can perform the natural solid or the cooled solid through the cooling means (400). Particularly, even in the case of forced cooling, cooling the mat 1000 vertically drained from the left and right can quickly and effectively perform cooling solidification without deforming the shape.

4 to 12 are views showing a fusion mold for a mat using gravity according to a second embodiment of the present invention.

The second embodiment of the present invention differs from the first embodiment of the present invention in that the principle of using gravity while taking a press-type mold structure is applied.

That is, similar to the first embodiment of the present invention, the second embodiment of the present invention comprises an inner filler 1, which is a member of no cushioning property, and a first sheet member 1, (10) and a second sheet member (20). However, unlike the first embodiment of the present invention, the second embodiment of the present invention applies the principle of using gravity while taking the press-type mold structure.

Referring to Figs. 4 to 8, the inner filler 1 and the first sheet member 10 and the second sheet member 20 engage with each other by a shape internally engraved, perpendicular to the ground surface. At this time, while the respective sheet members 10 and 20 are heated, the mat form frame on the upper face portion and the mat form frame on the lower face portion are engaged. To this end, the mat welding mold includes a first press mold body 100a and a second press mold body 200a.

The holding roller 600 passes the mat 1000 injection-molded from the first press mold body 100a and the second press mold body 200a and passes through one mat 1000, And holds the edge portion 30 of the display device 1000.

The mold control unit 300 controls the fusing heating unit 300a, the first press mold body 100a, the second press mold body 200a, and the holding roller 600. That is, while heating the inner filler 1 and the sheet members 10 and 20, the mold control unit 300 controls the molds of the upper face mold portion and the lower face portion of the second press mold body 200a in the first press mold body 100a, So that the gap between the holding rollers 600 is adjusted. The mats 1000 to which the sheet members 10 and 20 are fusion-bonded are taken out in a downward direction perpendicular to the ground surface by sequence control of the mold control unit 300 to be solidified.

In the above description, the mat form frame, that is, the first mat form frame of the upper face portion is formed by pressing the first press mold body 100a (100a) so that the first sheet member 10 on the upper face portion of the inner filler 1 is shaped to fuse the mat 1000 And the second mat form frame is formed in the inside of the second press mold body 200a so as to have the shape of the second sheet member 20 on the lower surface thereof it means.

4, the inner filler 1, the first sheet member 10 and the second sheet member 20 are disposed between the first press mold body 100a and the second press mold body 200a The members 1, 10 and 20 are heated in the fusing heating unit 300a and positioned between the first press mold body 100a and the second press mold body 200a. In this case, the holding roller 600 functions to narrow and hold the left and right gaps in order to determine the vertical limit position of the members 1, 10 and 20. Referring to FIGS. 7 and 8, The roller 600 serves to pull down the member while holding and opening. Accordingly, the members (1, 10, 20) stored in the first press-mold body (100a) and the second press-mold body (200a) via the fusing heating section (300a) It can be seen that it is completed. At this time, the fusing heating section 300a can be configured to heat the inner filler 1 while moving up and down.

5 shows a state in which the first press-mold body 100a and the second press-mold body 200a start to be engaged with each other. Referring to FIG. 5, the mold bodies 100a and 200a are engaged first and then the upper portions are engaged. In other words, the coupling process can be engaged in a castanet shape. As a matter of course, it is possible to perform fusion bonding directly as shown in Fig. 6, omitting the operation of engaging with the conical shape. However, in order to discharge the air remaining between the members 1, 10 and 20, .

That is, in order to minimize the residual air in the inner filler 1, the first sheet member 10, and the second sheet member 20, the second embodiment of the present invention has a mat- The upper and lower portions are brought into contact with each other in a vertical posture with respect to the ground surface, and then the lower portion is first contacted and then the upper portion is contacted.

FIG. 6 shows a state in which the mat molds on the upper surface portion and the mat molds on the lower surface portion are completely engaged with each other through a process of sequentially fitting them in a conical shape. The members (1, 10, 20), which are heated through the fusing heating unit (300a) in the coupled state and accommodated in the mold, have the shape of the mat (1000)

7 shows a state in which the mat 1000 is pulled out of the separated first press mold body 100a and the second press mold body 200a after a certain time has elapsed from a state where the mat 1000 is separated from the first press mold body 100a and the second press mold body 200a, And is drawn out to the lower portion of the mold as it passes through between the opened holding rollers 600. That is, when the mat 1000 is pulled out to the lower portion perpendicular to the ground surface, the grafted mats 1000 maintain a flat state because they do not violate gravity.

When the mat 1000 is pulled out to the lower portion, the operation in which the members 1, 10, 20 are heated while being accommodated continues in the upper portion. In order to explain such an operation, FIG. 8 shows that two processes are continuously performed. 7, when the mat 1000 reaches the edge portion 30 while passing through the holding roller 600, the holding roller 600 performs an operation of narrowing and holding the gap. Such a hold operation can be performed by automatically controlling the mold control unit 300 using a sensor for measuring light such as infrared rays, a microswitch, a capacitance, and the like.

4, the lower end of the holding roller 600 is a vertically suspended process in which the fused and bonded mat 1000 is vertically suspended, and the upper end of the holding roller 600 It is to be understood that the process of FIG. 8 is shown in FIG. In the following description, the upper end action of the holding roller 600 is the same as that of FIGS. 5 and 6, so that the description of the lower end action of the holding roller 600 will be omitted.

Referring to FIG. 8, the upper end of the holding roller 600 is housed inside the mold bodies 100 and 200, as shown in FIG. 4, in which the heated members 1, 10, The mat 1000 that has been fused in the working process of FIGS. 4 to 7 is vertically suspended by the holding action of the holding roller 600. FIG. That is, the mold control unit 300 controls the pressing force of the first sheet member 10, the second sheet member 20 and the inner filler 1 at the upper portions of the first press mold body 100a and the second press mold body 200a . The mold control unit 300 continuously controls the first and second press mold bodies 100a and 200a so that the combined mats 1000 are pulled out and suspended vertically. At this time, it is preferable to control the cooling means 400 for cooling in an air-cooling type, a spray type, or a water-cooling type in order to promote the solidification of the hanging mat 1000. On the other hand, in some cases, the cooling means may be excluded and solidified under natural conditions.

Through such a process, the mat 1000 having a physical property immediately after fusion is solidified to a flat state conforming to gravity, so that the solidification can be achieved without deforming the shape in principle, and furthermore, It is possible to perform molding as a sequence control in which residual air is minimized inside.

Referring to FIG. 11, when sufficient solidification has been achieved, the finished mat 1000 is cut by the cutter 500 and placed on the conveyor belt as a finished product. At this time, it is preferable to select the edge portion 30 to be fused between the first step and the second step, for example.

That is, a sequence control configuration in which the fusing heating unit 300a, the first press mold body 100a, the second press mold body 200a, and the holding roller 600 are interlocked and fused in units of one mat 1000 It is preferable to cut the edge portion 30, which is a unit of one mat (1000), as a cutter while the mold control unit 300 repeatedly performs. Here, the plurality of edge portions 30 may be set in one mat (1000). That is, the cutter 500 can be operated once for the plurality of edge portions 30, which can be adopted when forming the wrinkles inside the mat 1000 to fold the mat 100.

12 is a configuration in which the sliding rollers 700 are disposed at the upper ends of the mold bodies 100a and 200a to discharge air remaining in the respective members 1, 10 and 20 in FIG. When the sliding roller 700 slides upward from the bottom, the air remaining in the first sheet member 10, the second sheet member 20, and the inner filler 1 is discharged while heating and the mold bodies 100a And 200a can be achieved in order. Therefore, the air remaining in each of the members 1, 10, 20 can be minimized by the sliding roller 700. Particularly, the sliding roller 700 of FIG. 12 can achieve the desired air discharge purpose even if the above-mentioned "sequential control function of the first and second mold bodies 100a and 200a contact first from the lower end first " . Therefore, in FIG. 12, when the sliding roller 700 is used, it is preferable to perform sequence control so that the metal bodies 100a and 200a are directly engaged with each other.

As can be seen from the above description, the first press-mold body 100a and the second press-mold body 200a have a state perpendicular to the ground surface. This is for solidifying the fusion state in which the physical properties are weakened while passing through the fusing heating unit 300a through the interlocking of the holding roller 600 and the mold control unit 300, using the gravity.

Therefore, in order to set the time for optimizing the solid action or to match the material and shape of the mat 1000 to be molded, a fusing heating part 300a, a pair of first press die bodies 100a and 100b, It is preferable that the structure is such that the means for setting the sequence speed is provided in the structure in which the press mold body 200a and the holding roller 600 are integrally synchronized and operated in sequence.

13 and 15 are views showing a fusion mold for a mat using gravity according to a third embodiment of the present invention.

That is, similar to the first and second embodiments of the present invention, the third embodiment of the present invention is characterized in that the inner filler 1, which is a component of the cushioning property, and the upper and lower portions of the inner filler 1, To a mold for manufacturing a mat (1000) comprising a first sheet member (10) and a second sheet member (20) wrapping the first sheet member (10) and the second sheet member (20).

13 and 14, the mat 1000 is manufactured with the pair of first outer circumferential surfaces 101 and the pair of second outer circumferential surfaces 201 being in contact with each other while being perpendicular to the ground surface. To this end, the mat welding mold is composed of a first rotatable mold body 100 and a second rotatable mold body 100, which rotate a pair of first outer circumferential surfaces 101 and second outer circumferential surfaces 201 to face each other in opposite directions so as to form a mold, And includes a typical mold body 200.

The mat welding mold includes a mat form frame 102 on the upper face portion formed on the first outer peripheral surface 101 and a mat form frame 202 on the lower face portion formed on the second outer peripheral face 201. The fusion metal mold for mat is a fusion type mold for heating before the first sheet member 10, the inner filler 1, and the first sheet member 20 are accommodated in the mold 102 on the upper surface portion and the mold 202 on the lower surface portion. And a heating unit 300a.

The mat form frame 102 on the upper face portion rotates in a forward direction while receiving the first sheet member 10 and the lower face portion mat form frame 202 rotates in the reverse direction while receiving the second sheet member 2, And the internal filler 1 is accommodated between the sheet member 10 and the second sheet member 20. The inner filler 1 and the first sheet member 10 and the second sheet member 20 are interlocked and controlled so as to be heated 300a and welded to the mat 1000 to which the inner sheet 1 and the second sheet member 20 are joined. This can be controlled by the mold control unit 300. Under the control of the mold control unit 300, the mat 1000 to which the members 1, 10, and 20 are fusion-bonded is pulled out in a downward direction perpendicular to the ground surface to solidify.

13 and Fig. 14 differ from each other in that there is no guide roller 800 and sliding roller 700, which will be described below together with Fig. 15. Fig.

15, in place of the first rotatable mold body 100 and the second rotatable mold body 200, FIG. 15 shows a case in which a mat form mold of the upper face portion and a first mold form And a press mold body 100a and a second press mold body 200a.

13 and 14, a plurality of pairs of molds 102 and 202 can be disposed on the first and second outer circumferential surfaces of the rotatable mold bodies 100 and 200, A gear or a servo motor may be used so that the body 100 and the second rotatable mold body 200 rotate synchronously with each other.

The fusing heating unit 300a may heat only the internal filler 1 or heat the entire sheet members 10 and 20 and may control the guide roller 800 and the sliding roller 700 to be interlocked with each other. In the configuration in which the internal filler 1 is heated, the members 1, 10 and 20 are spaced apart from each other by a predetermined spaced interval, and then the internal filler 1 is heated first and then the sheet members 10 and 20 are gradually A sequence control method can be adopted. That is, the fusing heating unit 300a may include a fixed type or a slide type movable type.

Since the first press mold body 100a and the second press mold body 200a are described in FIGS. 4 and 11, detailed description thereof will be omitted.

Hereinafter, the above-mentioned description will be omitted and only different portions will be described.

In the first and second embodiments, the members 1, 10 and 20 are heated at the entrance of the mold. In contrast, in the third embodiment (Figs. 13, 14 and 15) The edge of the mold, the wrinkles and the like are welded together and solidified as the overall shape of the mat at the same time while completing the shape of the mat 1000 in the mold. That is, the gravitational force is applied vertically to the fusing process in the first embodiment and the second embodiment but in the heating process in the third embodiment.

At this time, the fusing heating unit 300a first heats the inner filler 1 in a state where the members 1, 10, and 20 are spaced apart from each other by a predetermined distance, (See Figs. 14 and 15). Further, the fusing heating unit 300a may be fixedly or slidably movable by being interlocked with the guide roller 800 and the sliding roller 700. FIG.

Particularly, in this configuration, the guide roller 800 and the sliding roller 700 do not depend on the arrangement positions of the respective member rollers 11 and 21, but widen and narrow the gap between the members 10 and 20 So that heat is conducted from the heating portion 300a to the internal filler 1. [ At this time, the sliding roller 700 separates the members 10 and 20 before heating, and after heating, the rolling roller 700 rolls by pressing to positively remove air remaining in the members 10 and 20 And discharging it. Therefore, from now on, regardless of whether the rotary mold bodies 100, 200 or the press-formed mold bodies 100a, 200a are fusion-bonded in a state in which no air remains.

In addition, in the third embodiment of the present invention, since solidification is achieved by cooling while being fusion-bonded, it is preferable that heat is radiated as cooling water inside the mold body at this time.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood that the present invention can be embodied in other specific forms without changing the shape of the synthetic resin foamed body.
