본 발명에 따른 블록완구(10)의 제조방법에 대해 설명 하기전, 본 발명에 따른 블록완구(10)를 이루는 합성수지 원재료인 폴리프로필렌(이하, "PP"라 한다) 또는 폴리에틸렌 테레프타 레이트(이하, "PET"라 한다) 또는 폴리에틸렌(이하, "PE" 라 한다)중 어느 하나를 활용한 상태에서의 블로우 몰딩(Blow Molding) 성형시 그 가공성과 성형성을 설명한다.Before describing the method for manufacturing the block toy 10 according to the present invention, polypropylene (hereinafter referred to as "PP") or polyethylene terephthalate (hereinafter referred to as "PP") which is a raw material of the synthetic resin constituting the block toy 10 according to the present invention. , "PET") or polyethylene (hereinafter referred to as "PE") will be described the workability and formability in the case of blow molding (Blow Molding) molding.

상기한, 합성수지는 본 발명 뿐 아니라, 그 외의 일반적인 사출 성형에서도 적용이 되고, 아래와 같이 상술하는 조건을 만족하여 작업하는 것을 기본으로 한다.As described above, the synthetic resin is applied not only to the present invention but also to other general injection molding, and is based on the work satisfying the conditions described below.

일반적으로 상기한 합성수지는 결정성 수지의 성형으로 명명하고, 다른 비결정성 수지는 단지 온도에 의하여 연화하여 성형되는데 비하여 상기 결정성 수지는 결정융점에서 비결정성으로 변화하며, 더욱 가열하면 연화한 후 성형되기 때문에 다음과 같은 여러가지 변화가 발생함으로 인해 블로우 몰딩시 하기와 같은 조건을 만족시킬 필요가 있는 것이다.In general, the above-mentioned synthetic resin is called molding of crystalline resin, and other amorphous resins are formed by softening only by temperature, whereas the crystalline resins are changed from crystalline melting point to amorphous, and when heated, softened and molded Therefore, it is necessary to satisfy the following conditions during blow molding due to various changes as follows.

첫째, 결정을 융해시키기 위해서는 열이 필요하기 때문에 성형온도까지 수지온도를 높이는데 많은 열량이 필요함으로 가소화 능력이 큰 기계가 필요하다.First, since heat is required to melt the crystals, a large amount of heat is required to raise the resin temperature to the molding temperature, so a machine with large plasticization capacity is required.

둘째, 상기와 같은 이유와는 반대로 고화할 때는 발열이 크므로 금형의 냉각시간을 충분히 할 필요가 있다.Second, on the contrary to the above reason, when solidifying, the heat generation is large, and thus, it is necessary to sufficiently cool the mold.

셋째, 상기한 합성수지는 결정체이므로 냉각되어 굳은 상태에서의 비중은 용융되었을 때의 비결정상태의 비중과 큰 차이가 생긴다.Third, the above-mentioned synthetic resins are crystals, so the specific gravity in the cooled and hardened state is significantly different from the specific gravity in the amorphous state when melted.

다시 말해서, 이것은 성형 수축률이 크다는 것을 의미함으로 충분한 사출양을 고려하여야 하는 것이다.In other words, this means that the molding shrinkage ratio is large, so that a sufficient injection amount must be considered.

넷째, 금형의 냉각 속도에 따라서 결정부분 전체에 미치는 비율, 즉 결정화의 정도가 변화하여 결정화의 온도가 낮을수록 비중은 작고, 즉 성형수축률이 작아 지며, 투명성은 증가함으로 그 온도를 적절히 유지하여야 한다.Fourth, as the rate of crystallization, i.e., the degree of crystallization, changes to the entire crystal part according to the cooling rate of the mold, the specific gravity is smaller as the temperature of crystallization is lower, that is, the shrinkage rate is reduced, and the transparency is increased. .

상기한 바와 같이, 블로우 몰딩시 합성수지 원재료의 조건과 가공조건이 적절히 이루어지는 것을 본 발명에 따른 투명 합성수지재로 제조되는 블록완구(10)에 적용되는 것을 전제로 하여 본 발명을 설명한다.As described above, the present invention will be described on the premise that the conditions and processing conditions of the synthetic resin raw material are appropriately applied during the blow molding are applied to the block toy 10 made of the transparent synthetic resin material according to the present invention.

도 4를 참조하면, 본 발명에 따른 블록완구(10)의 제조방법(500)은 블로우몰딩단계(510)와 자석접착단계(530)문양부재접착단계(550)로 대별된다.Referring to FIG. 4, the method 500 for manufacturing the block toy 10 according to the present invention is roughly divided into a blow molding step 510 and a magnet bonding step 530.

블로우 몰딩단계(510)는 예비성형단계(511)와 예열단계(513)와 에어블로우단계(515)와 성형단계(517)와 취출단계(519)로 대별된다.The blow molding step 510 is roughly divided into a preforming step 511, a preheating step 513, an air blow step 515, a molding step 517, and a takeout step 519.

도 5의 가)에 도시한 바와 같이, 예비성형단계(511)는 상기한 바와 같은 합성수지 원재료를 성형하기 위하여 상기 합성수지를 가열하여 유동상태로 만든 후, 1차 성형을 하기 위하여 인젝션 블로우 몰딩머신(미도시)에 구비된 압출기(미도시)로 보낸다.As shown in (a) of FIG. 5, the preforming step 511 heats the synthetic resin to form a fluid state in order to mold the synthetic resin raw material as described above, and then uses an injection blow molding machine to perform primary molding. It is sent to an extruder (not shown) provided in (not shown).

그런 다음, 도시하지는 않았으나, 소정 형상을 가진 금형에 의하여 예비성형품인 프리폼(11)으로 성형시키는 것이다.Then, although not shown, the mold is molded into a preform 11 as a preform by a mold having a predetermined shape.

이 프리폼(11)은 상기 인젝션 블로우 몰딩머신(미도시)에 의하여 24초 이상 30초 이하의 간격으로 다음 공정으로 이송되는 것이다. This preform 11 is the injection Blow The molding machine (not shown) is transferred to the next process at intervals of 24 seconds or more and 30 seconds or less.

그러나, 상기 프리폼(11)은 상기 예비성형단계(511)을 거친 후, 곧바로 냉각을 하게 되고, 그 냉각된 상기 프리폼(11)을 재성형하기 위해서는 재가열및 재가열된 온도를 유지하기 위한 공정을 수행해야 하기 때문에 예열단계(513)를 거쳐야 한다.However, after the preform 11 passes through the preforming step 511, the preform 11 is cooled immediately. In order to reshape the cooled preform 11, a preheating process is performed to maintain the reheated and reheated temperatures. Because it must be a preheating step (513).

이리하여, 상기 예비성형단계(511)후 재가열을 하여 블로우 몰딩하기 적당한 온도로 만들기 위한 예열단계(513)로 이어진다.Thus, preheating step 511 is followed by a preheating step 513 for reheating to a suitable temperature for blow molding.

도 5의 나)를 참조하면, 예열단계(513)는 상기한 바와 같이, 예비성형단계(511)에서 형성된 프리폼(11)을 성형하기 적당한 온도로 예열하는 것으로서, 280℃도 이상 320℃의 온도로 상기한 상기한 프리폼(11)을 예열하게 된다. Referring to (b) of FIG. 5, as described above, the preheating step 513 preheats the preform 11 formed in the preforming step 511 to a suitable temperature for molding, and has a temperature of 280 ° C or higher and 320 ° C. The preform 11 described above is preheated by the temperature.

이와 같이, 성형되기 용이한 온도로 예열된 프리폼(11)은 블로우 인젝터(53) 단부에 장착되어, 본 발명에 따른 블록완구(10)의 외형을 이루는 한조의 캐비티(52) 중앙에 위치하게 된다.As such, the preform 11 preheated to a temperature that is easy to be molded is mounted at the end of the blow injector 53, and is positioned at the center of a set of cavities 52 forming the outer shape of the block toy 10 according to the present invention. .

이 캐비티(52)는 좌,우로 나뉘어 지나 상기 몰드베이스(51)의 양단에 장착된 유압실린더(미도시)에 의한 작동으로 좌,우가 합쳐지게 된다.The cavity 52 is divided into left and right, and left and right are joined by an operation by a hydraulic cylinder (not shown) mounted at both ends of the mold base 51.

도 6의 가)에 도시한 바와 같이, 몰드 베이스(51)와 캐비티(52)의 결합으로 밀폐된 그 내부에 위치한 상기 프리폼(11)에 상기한 블로우 인젝터(53)를 통해 공기를 불어 넣는 에어블로우 단계(515)가 이어진다.As shown in (a) of FIG. 6, air for blowing air through the blow injector 53 to the preform 11 located therein, which is sealed by the combination of the mold base 51 and the cavity 52.
