Description of the Invention: [Technical Field] The present invention relates to a manufacturing method of a blow-molded product having a handle, and particularly to a manufacturing method of a blow-molded product having a handle. [Prior Art] The manufacturing method of a general plastic carcass is divided into two methods, namely, blow molding and injection molding. Blow molding is mainly carried out by directly blowing a plastic into a bottle after an injection molding machine is used to eject the plastic. Injection molding mainly uses a blown blow molding machine to sequentially inject molten PET raw material into a preform. After heating and holding the preform, the preform is blow molded to form a bottle of body reference. Figure 1, Figure 2 A blow molding having a handle is manufactured by the blow molding method. π %, mainly in a cavity 1丨 of a mold ,, a module 2 is preset. Thereby, after the plastic is injected into the cavity u, the plastic can be blown, so that the plastic follows the cavity u, and the gap 21 between the module 2 and the cavity U to form a predetermined shape. And has a blow of 31, the finished product 3. However, due to the blow molding method, the blow molded product 3 - the bottom surface 32 forms a relatively obvious butt line μ ' according to the mating surface of the mold i, and the finished product 3 is easy to follow. There are cases where there is a match. The blow-molded blow-molded product is blow-molded from the injection-molded preform, so the remaining line of the 'appearance' is less obvious and is not easy to break: 'The quality of the finished product is higher than that of the blow molding. Finished products, and more competitive products. ' 'The method of blow molding into a mold by a preform can not be put into the module because of 1282758. Therefore, the method of manufacturing a handle with a handle must be cleaned in the mold for the preform to be placed. The manufacturing method of molding has no finished product, and there is a lack of use. SUMMARY OF THE INVENTION Therefore, the object (5) of the present invention is to provide a manufacturing method of a blow-molded product having a handle for a blow-molded product-body-handle.

Step 3: The semi-finished product is placed in a full-shaped acupoint of a pair of blow molds. Step 4: The two modules are relatively protruded into the full-shaped cavity, and the portions of the semi-finished product adjacent to an edge are clamped to each other to form a hollow portion, and the semi-finished product is formed with respect to the portion of the module. The edge of the adjacent side and the portion of the hollow portion form a grip portion. Step 5: Blowing a 5 liter of preform, the semi-finished product is finished with a predetermined shape according to the space defined by the cavity and the module, and the hollow portion and the grip portion constitute a handle for damage. Step 6: Take out the finished product with the handle. The above and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. 3, 4, and 5, a preferred embodiment of the blow molding machine of the present invention comprises: a pair of injection molds 4, a pair of pre-blowing molds 5, a pair of blow molds, a mold 6, and a mold release device. 7 and number module 8. The pair of injection molds 4 and the pair, 6 1282758 lines are arranged in a reverse-circular β-pair blown film holder 6, and the mold-releasing device 7 is arranged in a wrap-around manner. Wherein, the pair of injections 4 and the retreat are substantially the same for the pair of two-mode structures, and the details are not described herein. The following is a detailed description of the portion of the pair of blow molds 6 and the modules 8 51. The blow molds 5 are contiguous with each other and have a pair of face cutters respectively opposite to each other - the center line L is formed with a left half chamber 521 盥 a right half chamber 522, and the width of the left half chamber 52 是 is slightly larger than the right Half chamber 522. The pair of blow molds 6 respectively have a mating surface 61, a full shape on the pair of Q faces 61, and a hole turn with the full mold cavity W. The modules 8 are respectively placed in the hole position of the pair of blow molds 6 and can be respectively positioned in the first position of the hole 63 (such as Item 5), and are located in the full-shaped cavity of the large extension person. The second position within 62 and opposite each other (see Figure 6). The modules 8 respectively have a guiding portion 81 with respect to the molding surface 4i, a convex portion 82 with respect to the full-shaped cavity 62, and a space between the guiding portion 81 and the protruding portion 82. a recessed portion 83, when the modules 8 are respectively located at the second position, the guide portions 81 and the raised portions 82 are flush with the mating face 61 of the pair of blow molding cookers 6 . > Fig. 3, Fig. 7 'The manufacturing method of the finished product with the handle, comprising the following steps: =, step - injection molding a preform 91 with the preform injection mold 4, when the injection molding tool 4 is opened 'By the bit (4) pair of injection mold 4 and the pair of pre-1282758 blowing wedges 5, the pair of blown film sets, a turntable above the mold-releasing device 7 (not shown) and a bottleneck mold 90 clip thereon Holding the preform 91 out of the injection molding apparatus 4: Refer to FIG. 3, FIG. 7, and the rotation of the turntable (not shown) for about 9:, after the opposite of the pair of pre-blowing molds 5, the test specimen 91 is placed. And entering the semi-molded cavity 52 in the pair of pre-eight eight, and pre-blowing the preform 91, so that the preform 91 follows the semi-molded cavity 52 to form a semi-finished product 92, as shown in Fig. 8, Fig. 9, two A half-92 疋 corresponds to the left and right half chambers 521, 522 forming a left half (2), and a right half 922 having a width slightly smaller than the left half of the yang. > Figure 3 w. After the mold is opened to the pre-blowing mold 5, the semi-finished product 92 is detached from the pre-blowing mold 5 by the neck mold 9 on the turntable (not shown). ^三·'Refer to Fig. 3, Fig. 7, Fig. 9', so that the modules 8 are respectively located in the position of the younger brother in the 筮Am 士力丄 of the meat of the tunnel 63.
