In particular, it is possible to manufacture a polyurethane foam sheet for an automobile having excellent sound absorption performance by manufacturing a conventional polyurethane foam sheet and adding only carbon nanotubes to the undiluted solution without significantly changing the process, a method of manufacturing an insulation, and an insulation to provide.

However, the mold for manufacturing such an insulation has the following problems with reference to FIG. 2.

(1) In a typical mold, a sheet material S having a single layer or a multilayer structure constituting an insulation is placed between a lower mold 10 and an upper mold 20 as shown in Fig. 2 (a) 20) is assembled as shown in FIG. 2 (b), and then the sheet S 'is produced. At this time, as the lower mold 10 and the upper mold 20 are joined together, the sheet raw material S is pulled into the mold so that it should be prevented.

Since the surface of the sheet S 'is formed in a complicated shape rather than a plate shape, the cavities 11 and 21 are formed on the facing surfaces of the lower mold 10 and the upper mold 20, . Thus, the sheet raw material S is pushed into the concave and convex portions as the molds are combined due to the concavo-convex shape.

(3) This necessitates the use of the sheet raw material S which is larger than the size of the sheet S ', which unnecessarily raises the material cost. Particularly, the portion that is pulled into the mold causes wrinkles and the like, leading to quality defects.

(4) Thus, as shown in Fig. 2, the clamp 12 is mounted on the lower mold 10 so that the clamp 12 fixes the sheet stock S and is pulled into the mold so as not to enter. However, the conventional clamp 12 has the following problems.

(5) As shown in Fig. 2, a plurality of clamps 12 are provided on the lower mold 10 at predetermined intervals. At this time, the lever 12 'is mounted so that each clamp 12 operates at one time to fix or release the sheet stock S. However, since the lever 12 'has to be operated by a worker, the productivity is deteriorated and there is a risk of a safety accident.

(6) The conventional lever 12 'has to be manually operated by the operator, and the sheet material S is pulled into the mold as it enters the mold as the mold is pinched without operating the lever 12' It may lead to product failure.

(7) In addition, since the operator must operate the lever 12 'every time the mold is assembled, it may lead to a safety accident due to repetition of a simple operation, which requires improvement.

Prior to this, terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary meanings, and the inventor shall appropriately define the concept of the term in order to best describe its own design It should be construed as meaning and concept consistent with the technical idea of this invention.

Therefore, the embodiments shown in the drawings and the drawings are only exemplary embodiments of the present invention and are not intended to represent all of the technical ideas of the present invention. Therefore, various equivalents And variations may be present.

(Configuration)

As shown in FIGS. 3 and 4, the automotive insulation mold according to the present invention includes a lower mold 100 and a lower mold 100, which are placed on both sides of a base material P and sandwiched therebetween, And includes a mold 200.

In particular, the lower mold 100 is configured such that the clamp 110, which is pulled into the mold when the base stock P is formed and is fixed so as not to enter the mold, is automatically formed as the mold is poured and released. 110 are not required to be operated, so that a malfunction can be caused so that a quality defect and a safety accident that is injured by the operator can be prevented in advance.

Hereinafter, this configuration will be described in more detail. Here, the reference numeral "P" is a base material for forming the insulation, and it is composed of one layer or several layers. "P" " represents an insulation base material formed by inserting such a base material into a mold.

The lower mold 100 and the upper mold 200 are configured to face each other as shown in Figs. 3 and 4. At this time, the base material P is placed therebetween, and the lower mold 100 supports the base material P from below.

The lower mold 100 and the upper mold 200 are provided with cavities 130 and 210 for molding the shape of the insulation base S 'on the surfaces facing each other as shown in FIGS. 3 and 4, .

Particularly, when the lower mold 100 and the upper mold 200 are assembled together, the lower mold 100 may be formed of the base material P because of the cavities 130 and 210, as shown in FIGS. 3 and 4, A plurality of clamps 110 are mounted at predetermined intervals so as to fix the edge of the base stock P so that the edge of the base stock P is not pulled into the mold.

Here, the clamp 110 can be used as long as it can fix the edge of the base material P. For example, the clamp 110 may be formed in a pin shape so as to be fixedly attached to the base material P, or may be configured such that the adhesive plate formed in a plate shape is pressed and fixed to the base material P by pressing. In addition, it will be readily apparent to a person skilled in the art that any structure can be used if it is configured so that the edge of the base material P is pushed or penetrated so as not to be pulled into the mold.

At this time, the clamp 110 may be rotated or linearly moved in various manners to fix the base material P, and the pneumatic or hydraulic cylinder 111 may be fixed as shown in FIGS. 3 and 4 Is preferably used. It will be readily apparent to a person skilled in the art that a structure can be constructed between the clamp 110 and the pneumatic or hydraulic cylinder 111 so as to eliminate the interference which may occur when the link structure is added and operated .

The plurality of clamps 110 are configured to be able to operate simultaneously by receiving air or oil pressure at the same time through one control valve 112 as shown in FIG. 3 and FIG.

Meanwhile, the control valve 112 controls the sensing unit 120 to move in the mold so that the lower mold 100 and the upper mold 200 are operated as they are assembled and released, as shown in FIGS. 3 and 4 .

The sensing means 120 may be a micro or electronic sensor. However, it is preferable to configure the sensing means 120 so as to be able to easily recognize the merging state and the releasing state by using a switch 122 capable of sensing the operation of the metal mold Do. That is, as shown in FIGS. 3 and 4, the sensing means 120 includes a protrusion 121 mounted on the upper mold 200, and a lower mold (not shown) 100, respectively. The switch 122 causes the clamp 110 to automatically operate by causing the protrusion 121 to be turned on or off so that the control valve 112 is opened or closed so that the air or the hydraulic pressure is applied to or discharged from the cylinder 111.

In a preferred embodiment of the present invention, the control valve 112 preferably employs a mechanical valve. A mechanical valve is a valve made by a conventional technique that turns on and off with a mechanical structure. Since such a mechanical valve operates mechanically, it can be configured to operate through a mechanical operation through merging and demolding without separately configuring the sensing means 120 for detecting the merging and releasing of the mold.

As described above, according to the present invention, since the clamp for fixing the edge of the base material is automatically operated so that the base material can not be pulled into the mold as the mold is assembled, the operator does not need to manually operate the clamp, It is possible to solve in advance the problem of the defect of the product which may occur as the edge of the base material is not fixed because the clamp is not operated.

In addition, since the operator does not have to check the clamping operation every time the operator performs the assembling, it is possible to expect an effect of preventing the safety accident by improving the working environment while increasing the concentration.
