Description

[0001] Apparatus for Ejecting Molded Product [0002]

More particularly, the present invention relates to an apparatus for taking out a molded article from an integrated core mold of a vacuum molding machine in a simple manner while simplifying the process as much as possible, And a molded core take-out apparatus provided with a single-piece core mold capable of producing the same.

In general, a vacuum molding machine is an apparatus for molding a product in a predetermined shape using a molding material such as rubber or silicone. In molding a molding material to be inserted into an upper mold and a lower mold, When external air is introduced into the mold, it is possible to prevent the occurrence of defects in the molded product due to bubbles, thereby obtaining high-quality molded products. In addition, a vacuum chamber is installed to separate and discharge odor and harmful gas generated during the molding operation .

Furthermore, in the case of molding a small projecting part of a molded product or a molded product having a complicated internal structure in a vacuum molding machine, it is difficult to manufacture a product by simply opening the basic mold structure (upper mold and lower mold). .

However, in the molding operation using the core mold, there is a problem that the overall mold size becomes large and the structure of the apparatus becomes complicated in order to constitute the structure for directly separating the formed molded article from the inside of the mold. Thus, in order to take out the molded article from the core mold There has been a problem in that the operation is difficult and long because the forced product is taken out by applying the forced force which is carried out based on the manual operation of the operator and the molded product is deformed.

As a conventional technique disclosed for solving the above problems, Korean Patent Registration No. 1215296 (Dec. 18, 2012) discloses a heat exchanger having a top plate in which a penetrating core inserting portion is formed at a center portion, An insert that directly contacts an insert core having one end mounted on the upper plate to prevent the insert core from being detached from the upper plate at the time of taking out the injection product, A slider that is in contact with the insert core fixing cam and separates the insert core fixing cam from the insert core in a direction away from the insert core after the insert is taken out by the die pin in the insert core, A through hole is formed and reciprocating along the through hole, And an inclined cam for slidably sliding the slider so that the slider can be easily taken out without damaging the molded article.

However, the above conventional take-out apparatus has a limitation in that it can only take out the spool bobbin formed for the purpose of winding electric wires, strings and the like from the molding machine, and can not take out other complicated shaped articles. That is, as shown in Fig. 1, there is a limit in that it is impossible to take out the bellows-shaped molded article A such as a cable housing which is one of the automobile parts.

Therefore, in order to take out the bellows-shaped molded article A such as the cable housing, air is injected between the molded article and the core mold to take out the molded article with the bellows being inflated like a balloon.

However, in the case of the mold and core mold of the molding machine, since the gap between the molded articles is formed so as to be able to produce the maximum amount of molded articles at a time in a limited working area, the space for the operator's hand is insufficient during the take- Further, during molding of the product, the molding material is pressed and held at a constant temperature for a certain period of time to maintain the molded article at a temperature (150 to 180 ° C) for a predetermined time so that the molded article can be completely formed, And the molded article itself is in a heated state at a high temperature, there is a problem that an image may be taken during the taking-out work of the molded article.

2, after separating the core metal mold 10 from the lower mold, the core metal mold 10 is divided into upper and lower parts again to form a molded product So that the work space of the operator for taking out the molded article can be ensured.

However, in the related art, since the core mold 10 is separated from the lower mold under the condition that the molded product is molded, the work for the core mold 10 is required to be separated and joined together. And the production efficiency of the product is lowered.

In addition, since the conventional arrangements such as guide means for guiding the core molds 10 to be separated from each other and a plurality of stoppers for supporting the separated core molds 10 are required, there is a problem in that the equipment cost of the take- there was.

Preferably, the mounting means 340 is inclined upward toward the upper side on the vacuum molding machine 100 to easily grasp or mount the air blow-out portion 300 from an operator.

When a molding material such as rubber or silicone is placed on the lower mold 125 of the lower frame 120 and the core member 210 of the core mold part 200, The lifting unit 150 is lowered and the core mold part 200 is engaged with the lower mold part 125 and the transfer plate 140 linearly moves backward to correspond to the upper mold part 115 of the upper frame 110 The lower mold 125 is positioned. The upper frame 110 and the lower frame 120 are vertically moved up and down so that the upper mold 115 and the lower mold 125 are coupled to each other and heat is applied in a vacuum state to mold the molded article A . The upper frame 110 is moved upward so that the upper mold 115 and the lower mold 125 can be separated from each other and the lower frame 120 moves downward, The mold 125 and the core mold part 200 are linearly moved forward. At this time, the lifting unit 150 moves up and down the core mold part 200 to move the core mold part 200 from the lower mold 125, so that the molded product A can be taken out from the worker in a state . The operator grips the air injector 320 of the air blowing unit 300 to position the blowing member 330 toward the molded product A formed on the core member 210 of the core mold unit 200 Air is injected from the air injector 320, so that the molded article A is taken out.

In other words, according to the molded product take-out apparatus having the integrated core die according to the present invention constructed as described above, since the core mold portion in which the plurality of core members are arranged and arranged by the number of molded products is vertically integrated, It is possible to simplify the work of the operator, reduce the time required for taking out the molded product, and improve the productivity of the product, as well as mass production.

In addition, since the foot is integrated with the air injector for high-pressure air injection and the take-out member for taking out the molded product, it is possible to easily operate the work by taking only one hand of the worker to take out the work, Do.

Although the preferred embodiments of the molded article take-out apparatus with the integral-type core mold according to the present invention have been described above, the present invention is not limited thereto, but may be variously modified and embodied within the scope of the claims, specification and accompanying drawings And is also within the scope of the present invention.
