[0008] S3: Injection molding: The injection molding machine is closed and the product is injected;

[0009] S4: Take out the product: take the product out of the injection mold after the product is formed;

[0010] S5: Taking out the insert: After the product has cooled down, the combined insert is taken out from the product by using a jig and applying pressure manually;

[0011] S6: Collecting the inserts: Collect the inserts taken out in sequence and can be used for the next product molding.

[0012] Preferably, the insert can be designed according to the internal contour of the product and can be a combination of two or more inserts that are shaped like the internal contour of the product.

[0013] Preferably, the jig can be configured with a desired number of jigs conforming to the configured combination.

[0014] Preferably, the insert and the fixture can both be made of stainless steel.

[0015] In addition, the present invention also provides a product, which is a product formed by the above-mentioned combined molding method.

[0016] The beneficial effect of the present invention is that the present invention adopts a molding method of a combined insert, which adopts a combined insert to mold a product. After the product is molded, the combined insert can be taken out separately with the assistance of a jig and manual pressure, so that the complex undercut product can be demolded, thereby realizing the molding of the complex undercut product.

[0026] To further illustrate the technical means and effects of the present invention, the following is a detailed description in conjunction with the embodiments of the present invention and the accompanying drawings.

[0027] The present invention provides a method for forming a combined insert, which comprises the following steps:

[0028] S1: Designing the insert 100: Designing the combined insert 100 in accordance with the internal contour of the product 120 and designing a jig (111, 112) in accordance with the internal contour of the combined insert 100. The jig (111, 112) is used to assist in taking out the combined insert 100. In this embodiment, Figures 4-5 As shown, the first inlet 101, the second inlet 102, the third inlet 103, and the fourth inlet 104 can be designed to conform to the interior of the product 120, and the first fixture 111 conforms to one end of the first inlet 101 and the second fixture 112 conforms to one end of the second inlet 102;

[0029] S2: Assembling the insert 100: Assembling the insert 100 according to the design structure, and placing the assembled insert 100 into a mold;

[0030] S3: Injection molding: The injection molding machine is molded and the product is injected and molded 120;

[0031] S4: taking out the product 120: after the product 120 is formed, taking the product 120 out of the injection mold;

[0032] S5: Taking out the insert 100: After the product 120 is cooled, the assembly insert 100 is taken out from the product 120 in sequence by using the jigs (111, 112) and manually applying pressure. In this embodiment, Figure 6 As shown, firstly, the first fixture 111 is inserted into the first slot 105 of the first insert 101, and the first insert 101 is pulled out, as shown in FIG. Figure 7 As shown, the second fixture 112 is inserted into the second slot 106 of the second insert 102, and the second insert 102 is pulled out, as shown in FIG. Figure 8 As shown, the third insert 103 can be removed by manually applying pressure to the end of the third insert 103 to avoid the air gap. Fig. 9 As shown, the fourth insert 104 can be removed by manually applying pressure to the end that avoids the air gap;

[0033] S6: Collecting the inserts 100: Collecting the first insert 101, the second insert 102, the third insert 103, and the fourth insert 104 taken out in sequence, and can be used for molding the next product 120.
