Description

&Lt; Desc / Clms Page number 1 > A mold unit having a clamp and a regulating device,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a mold unit, and more particularly, to a mold unit in which a clamp and a regulating device are provided in a mold used for forming an automobile interior material.

In general, the built-in trim is produced by injection molding using plastic. Up to now, a single piece (door upper trim, door lower trim, door center trim, door inside handle garnish, etc.) , And a method of completing the manufacture of the built-in trim by mutually assembling (thermally fusing or screwing) each manufactured product.

Usually, the built-in trim is injected separately from the first and second injection articles, and then joined using a method such as tapping or fusing. At this time, the first and second injection articles are door trim of a single article, a door-inside garnish, and the like, and recently, each component is integrally injection molded in consideration of productivity and design. In this case, when the individual parts constituting each built-in trim are formed in different colors, a separate injection machine is required to manufacture the individual parts of the respective parts, so that the facility investment cost is raised and the manufacturing cost Can rise.

However, if the molded trim is molded as described above, it is difficult to prevent wrinkling and rupture by adjusting the tension and the amount of the material, and since it is necessary to adjust it according to the molding conditions, the productivity may be low and defects may be increased.

Korean Registered Patent No. 10-1282787 (Registered on July 1, 2013)

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and provides a mold unit having a clamp and a control device improved in structure of an automotive interior material molding die.

The first and second clamps may further include first and second fixing units formed at positions corresponding to each other.

The first and second clamps may seal the connection portions of the first and second molds.

Further comprising first and second fixing portions provided at mutually corresponding positions of the first and second dies for fixing the first and second dies, wherein the first and second fixing portions are formed by a complementary coupling Can be fixed.

The adjusting device may have a height adjusting part formed therein with a tapping function, and the height adjusting part may be changed in accordance with the material to be introduced.

According to the present embodiment as described above, it is possible to more easily adjust the tension and the input amount of the workpiece, thereby preventing wrinkles and breakage. Further, since it is easy to adjust according to molding conditions, productivity can be improved and defects can be reduced.

In addition, it is possible to reduce the number of workers and the input cost, thereby reducing manufacturing costs.

2 is a view showing a second mold of the mold unit having the clamp and adjustment device according to the present embodiment,
Fig. 3 is a view showing a combined state of the first and second dies.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains. The present invention may be embodied in many different forms and is not limited to the embodiments described herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same reference numerals are assigned to the same or similar components throughout the specification.

FIG. 1 is a view showing a first mold of a mold unit having a clamp and a regulating device according to the present embodiment, FIG. 2 is a view showing a second mold of a mold unit having a clamp and regulating device according to the present embodiment, 3 is a view showing a state of engagement of the first and second dies.

As shown in FIGS. 1 to 3, the mold unit having the clamp and adjusting device according to the present embodiment includes a first mold 10, a second mold 20, a first clamp 110, a second clamp 120 And an adjusting device 200. [0033]

The first mold 10 forms a first injection molding, and a built-in trim for a vehicle can be injection-molded using the first molding material.

The second mold 20 may be coupled to the first mold 10 to form a second injection material of the same material or the same material as the first injection material. At this time, the first and second dies 10 and 20 may be formed in different shapes, or they may be combined with each other in a complementary shape so that the door trim or the interior material may be injection-molded into a thin thickness.

Meanwhile, the first and second molds can be detachably coupled by the first and second fixing portions 11 and 21. At this time, the first and second fixing parts 11 and 21 may be provided in a complementary shape. If the first and second fixing parts 11 and 21 have a bolt structure, the other side may be provided with a nut structure. According to the present embodiment, the first fixing portion 11 may be provided with a bolt, and the second fixing portion 21 may be provided with a nut.

The first clamp 110 may be disposed on a circumferential surface of the first mold 10 which abuts the second mold 20. According to the present embodiment, the first clamp 110 is configured to surround the side surface of the contact surface of the first and second molds 10 and 20, It is possible to prevent the ash from leaking.

The second clamp 120 may be disposed on a circumferential surface of the second mold 20 which abuts the first mold 10. According to the present embodiment, the second clamp 120 is configured to surround the side surface of the contact surface of the first and second molds 10 and 20, It is possible to prevent the ash from leaking.

The adjustment device 200 adjusts the positions of the first and second clamps 110 and 120 so that at least one or more pluralities of the clamps 110 and 120 are disposed on the circumferential side of the first and second clamps 110 and 120 at regular intervals .

The first and second clamps 110 and 120 may further include first and second fixing units 111 and 121 formed at positions corresponding to each other. The first and second fixing units 111 and 121 may fix and seal the positions of the first and second clamps 110 and 120.

The adjusting device 200 is formed with a height adjusting part formed therein with a tapping function, and can be moved according to the material to be introduced. A plurality of regulating devices 200 may be disposed on the circumferential surfaces of the first and second clamps 110 and 120 as shown in FIG. The adjustment device 200 adjusts the close contact position of the first and second clamps 110 and 120 so that the degree of contact between the first and second molds 10 and 20 is reduced , So that additional material can be introduced through the gap.

According to the above-described configuration, the material corresponding to the fabric is primarily clamped by the first and second clamps 110 and 120, and secondarily, the fabric is once again held by the regulating device 200 You can give. Therefore, since the adjusting device 200 can be operated up and down, the position can be adjusted according to the shape and the material.

Accordingly, it is possible to reduce the input rate of the worker during the product manufacturing process, reduce the product defect rate, maintain the quality of the finished product at the time of work, and simplify the structure, so that the productivity of the product can be improved.

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, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
