The mold part 280 may include an upper mold 290 and a lower mold 270. A first molding portion 291 for molding an upper surface of the object to be molded may be formed on one surface of the upper mold 290. A second molding portion 271 for molding the lower surface of the object may be formed on one surface of the lower mold 270.

The stopper portion 250 may determine a lower limit of the upper block 300. The lower limit may be a distance or a position at which the upper block 300 can be maximally approached in order to mold the object to be molded into a set shape.

Referring to fig. 4, 5(a) and 5(b), the detaching unit 310 may include a pushing part 310 moving together with the upper block 300 and an elastic part 350 pressurizing the pushing part 310.

The push part 310 may be opposite to the upper portion of the mold unit 200, specifically, the upper mold 290. The push portion 310 may push the mold unit 200 from the upper block 300. The pushing part 310 may include an elastic part 350 such as a spring providing an elastic force, a pneumatic cylinder providing pneumatic pressure, a motor providing electric power, and the like.

When the upper block 300 is closely attached to the mold unit 200, the pushing part 310 may be retracted into the upper block 300. If the upper block 300 is separated from the mold unit 200, the push portion 310 may protrude from the inside of the upper block 300 to push out the mold unit 200.

A groove-shaped insertion portion 309 into which the push portion 310 is inserted may be formed at one surface of the upper block 300 facing the mold unit 200. The elastic part 350 may provide an elastic force to protrude the push part 310 from the insertion part 309 of the upper block 300.

A first time point at which the push part 310 is brought into contact interference with the mold unit 200 during the approach of the upper block 300 toward the mold unit 200 may be defined. A second point in time may be defined at which the push part 310 is released from the mold unit 200 during the process of the upper block 300 moving away from the mold unit 200.

The pushing part 310 receives an elastic force, and maintains the state of being in close contact with the mold unit 200 from the first time point to the second time point, regardless of whether or not the pushing part 310 is inserted into the upper block 300.

When the mold unit 200 is pressurized by the upper block 300, the push part 310 may be inserted into the insertion part 309 of the upper block 300 by a pressurizing force of the upper block 300 greater than an elastic force of the elastic part 350. The pushing portion 310 inserted into the insertion portion 309 can maintain a state of being closely attached to the mold unit 200 by an elastic force as shown in fig. 5 (a).

As shown in fig. 5(b), when the upper block 300 is separated from the mold unit 200, the pushing portion 310 may protrude from the insertion portion 309 while being kept in close contact with the mold unit 200 by an elastic force, and push out the mold unit 200. According to the present embodiment, the push portion 310 can remove the mold unit 200 from the upper block 300 without damaging the pushability of the object to be molded.

The pushing part 310 may be formed in a strip shape traversing one surface of the upper block 300 facing the mold unit 200. At this time, the push portion 310 may extend in the second direction. Therefore, the present invention can be applied to mold units 200 of various sizes and mold units 200 of various numbers.

For example, when the upper block 300 presses the mold part 280, a first pushing part 311 contacting the mold part 280 on the first virtual line i1, a second pushing part 312 contacting the mold part 280 on the second virtual line i2, and a third pushing part 313 contacting the mold part 280 on the third virtual line i3 may be provided. The plurality of pushing parts 310 may be formed in parallel with each other. More than the number of the pushing parts 310 corresponding to the virtual lines i1, i2, i3, etc. traversing the plurality of mold parts 280 may be formed.

According to the present embodiment, the push part 310 may continuously extend from one side end of the upper block 300 to the other side end of the upper block 300. Similarly, the insertion portion 309 may be formed with a groove (trench) continuously extending from one end of the upper block 300 to the other end of the upper block 300 corresponding to the pushing portion 310.

Wing portions 370 protruding to both sides, respectively, may be provided at the upper block 300 to support the respective push portions 310. The wing 370 may be disposed on the upper or side of the upper block 300.

The elastic part 350 may connect the end of the push part 310 and the wing part 370 and elastically pressurize the end of the push part 310 with the wing part 370 as a supporting point. A connection part 330 connecting the elastic part 350 and the push part 310 may be interposed between the elastic part 350 and the push part 310. The insertion portion 309 or the connection portion 330 may guide the push portion 310 to move in the third direction.

A door 9 that can be opened and closed may be provided on one side of the main chamber 3. The interior of the main chamber 3 can be exposed by the door 9, and the maintenance of the components inside the main chamber 3 can be facilitated.

In a state where one side of the main chamber 3 is opened by the door 9, it is preferable that the view is not blocked by the elastic portion 350, the pushing portion 310, or the like. A bent portion 319 for bending a part of the pushing portion 310 may be provided at the door 9 side end portion of the pushing portion 310. The curved portion 319 may be opposite the door 9. The bent portion 319 may be bent from the mold unit 200 in a direction toward the upper block 300. The bent portion 319 may be bent from a surface of the upper block 300 opposite to the mold unit 200 toward the wing portion 370.

Referring to fig. 6(a), 6(b) and 7, a groove-shaped detaching portion 320 is illustrated as another embodiment of the detaching unit 310.

The detachment unit 310 may include a detachment part 320 formed in a groove shape of the upper block 300. When the force with which the mold unit 200 adheres to the upper block 300 is small, the release portion 320 may be positively utilized instead of the push portion 310.

The escape portion 320 may include a groove (trench) or a groove formed at one surface of the upper block 300 opposite to the mold unit 200. A plurality of escape portions 320 having a groove (trench) or groove shape may be formed at equal intervals.

As an example, as shown in fig. 6(a), the escape portion 320 may be formed with a groove (trench) extending in the second direction. As an example, as shown in fig. 6(b), the detachment portion 320 may be formed with a lattice-shaped groove intersecting the first direction and the second direction.

The width of the release portion 320 is preferably greater than or equal to 1/3, which is the diameter of the mold unit 200 or the mold portion 280 that is in contact with the upper block 300.

According to the escape part 320, the area of the mold unit 200 contacting the upper block 300 can be reduced. After the contact area is reduced, accordingly, the force with which the mold unit 200 adheres to the upper block 300 may be weakened. As a result, the mold unit 200 and the upper block 300 can be easily separated.
