Hereinafter, a two-color mold will be described by taking a product having soft rubber on both sides of a hard rubber formed by injection molding using the two-color mold as an example.
Referring to fig. 1 to 4, the dual-color mold includes a front mold assembly 100 and a rear mold assembly 200. The front mold assembly 100 includes a front mold plate 110, and a first front mold cavity 111 and a second front mold cavity 112 are formed on the front mold plate 110. The rear mold assembly 200 includes a rear mold plate 210, a rear mold core 220, a first rear mold insert 230 and a second rear mold insert 240, the rear mold core 220 is disposed on the rear mold plate 210, the first rear mold insert 230 is disposed in the rear mold core 220 to form a first rear mold cavity 211, the second rear mold insert 240 is disposed in the rear mold core 220 to form a second rear mold cavity 212, and the rear mold plate 210 can drive the rear mold core 220 to act, so that the engagement between the rear mold core 220 and the first rear mold insert 230 and the second rear mold insert 240 is switched. The first front mold cavity 111 forms a first cavity for one shot injection when joined with the first rear mold cavity 211 and the second front mold cavity 112 forms a second cavity for two shot injection when joined with the second rear mold cavity 212.
The front mould of the double-colored mould has two different front mould die cavities, and the back mould has back mould benevolence 220 and two different back mould inserts, thereby forms different back mould die cavities through the back mould insert in the back mould benevolence 220 of switching, switches the front mould die cavity relative with back mould benevolence 220 to can realize when the secondary is moulded plastics, front mould die cavity and back mould cavity all change, form the secondary double-sided injection moulding.
The process of injection molding the product by the bicolor mold in the embodiment is as follows: when the front mold plate 110 and the rear mold plate 210 are closed for the first time, the first front mold cavity 111 and the first rear mold cavity 211 are combined to form a first cavity, and casting materials are introduced into the first cavity to form a primary product. Then, the back mold plate 210 drives the back mold core 220 and the primary product to act together by driving the back mold plate 210, so that the back mold core 220 is jointed with the second back mold insert 240 to form the second back mold cavity 212. And then the rear mold plate 210 and the front mold plate 110 are assembled, the second front mold cavity 112 and the second rear mold cavity 212 are combined to form a second cavity, and the primary products arranged in the second front mold cavity 112 and the second rear mold cavity 212 are used as secondary pouring cores, specifically, cavities for secondary injection are respectively formed between the first front mold cavity 111 and the primary products and between the second rear mold cavity 212 and the secondary products, so that after casting materials are filled into the cavities, the double-sided stacking of the primary products can be completed.
The first rear mold insert 230 is disposed corresponding to the first front mold cavity 111 such that the first rear mold cavity 211 can be opposed to the first front mold cavity 111, and the second rear mold insert 240 is disposed corresponding to the second rear mold cavity 212 such that the second rear mold cavity 212 can be opposed to the second front mold cavity 112. The rear mold plate 210 may be lifted up with respect to the first and second rear mold inserts 230 and 240 so that the rear mold insert 220 is separated from the rear mold insert, and then the rear mold insert and the front mold cavity with respect to the rear mold insert 220 may be replaced by rotation or translation, and the rear mold plate 210 is moved down so that the rear mold insert 220 and the rear mold insert are re-engaged to complete the switching of the rear mold cavity.
The rear mold insert 220 may be directly formed on the rear mold plate 210, or may be a component assembled separately from the rear mold plate 210, and the cavity on the rear mold insert 220 is a partially formed structure of the rear mold cavity, and is joined to the rear mold insert to form a complete rear mold cavity.
In this embodiment, two rear mold inserts 220 are centrally and symmetrically disposed on the rear mold plate 210, a first rear mold insert 230 and a second rear mold insert 240 are disposed in the two rear mold inserts 220, respectively, and the rear mold plate 210 can drive the two rear mold inserts 220 to rotate so that the first rear mold insert 230 and the second rear mold insert 240 are interchanged in the two rear mold inserts 220. This enables the first and second cavities with the product to be interchanged by rotating the rear mold plate 210. The product in the original first cavity is switched to the second cavity along with the rotation of the rear mold plate 210 and the rear mold insert 220. The rear mold assembly 200 of this structure can ensure that the appearance of the rear mold assembly 200 remains unchanged and the structure of the rear mold assembly 200 remains unchanged when the rear mold cavity is changed.
The positions of the first rear mold cavity 211 and the second rear mold cavity 212 on the rear mold plate 210 are unchanged relative to the front mold assembly 100 when the rear mold plate 210 drives the rear mold insert 220 to rotate, the first rear mold cavity 211 is always opposite to the first front mold cavity 111, the second rear mold cavity 212 is always opposite to the second front mold cavity 112, and the rotation of the rear mold plate 210 is actually equivalent to transferring the product injection molded from the first cavity to the second cavity, so that the cavity where the product formed at one time is located is changed.
The structure of the rear mold assembly 200 described above also enables the two-color mold to simultaneously mold two products at the time of injection molding. When the first injection molding is performed, the first cavity and the second cavity are cavities, casting materials are introduced into the first cavity to perform injection molding to form a primary product, then the rear mold plate 210 is rotated to drive the rear mold insert 220 and the primary product, and the first cavity is switched to the second cavity in the cavity where the primary product is located. At this time, the first cavity is a cavity, the second cavity is filled with a primary product, casting materials are introduced into the first cavity and the second cavity, primary injection molding and secondary injection molding are respectively completed, and when the rear template 210 is separated from the front template 110, the secondary molded product is ejected, and then the cavity-shaped first cavity is formed again, so that the process is repeated. Except for the first injection, the two cavities of the bicolor mold are both two cavities for injection molding simultaneously, so that the injection molding efficiency can be effectively improved.
The rear mold assembly 200 further includes a driving shaft 250 for driving the rear mold plate 210 to move and rotate.
