Embodiment Construction

[0014] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0015] The technical scheme of concrete implementation of the present invention is:

[0016] Such as figure 1 and figure 2 As shown, a two-color mold to prevent product from falling off includes a one-shot module and a two-shot module located on one side of the one-shot module. The one-shot module and the two-shot module are respectively provided with a rear mold, two The back mold structure is the same, and the back mold includes a lower template 1 and a lower mold core 2 arranged on the top of the lower template 1; The front mold includes an upper mold plate and an upper mold core located at the bottom of the upper mold plate, the upper mold core and ...

Abstract

The invention discloses a double-color mold capable of preventing products from falling off. The double-color mold comprises two rear mold bodies which are the same in structure; each rear mold body comprises a lower mold plate and a lower mold core; the formed first-color products are left in the lower mold cores; two sliding blocks are arranged on each lower mold plate, and the sliding blocks are slidably connected to the tops of the lower mold plates through guide sliding straight grooves; mounting holes are formed in the groove bottoms of the guide sliding straight grooves, and the mounting holes are located in the sides, away from the lower mold cores, of the sliding blocks; vertical oil cylinders with upward output shafts are mounted in the mounting holes, and lifting blocks are connected to the output shafts of the oil cylinders; first bevel faces are arranged at the upper ends of the lifting blocks and incline in the direction of the lower mold cores from top to bottom, and thesides, away from the lower mold cores, of the sliding blocks are provided with second bevel faces corresponding to the first bevel faces; and reset springs and pressing blocks are connected to the sides, close to the lower mold cores, of the sliding blocks, the reset springs are fixed into the guide sliding straight grooves, and the pressing blocks are located above the guide sliding straight grooves. According to the double-color mold capable of preventing the products from falling off, the problem that the first-color products are prone to falling off when rotating along with the rear moldbodies is solved effectively.

Description

technical field [0001] The invention relates to a two-color mold for preventing product falling off. Background technique [0002] The design principle of the general two-color mold is that after the first-color product is injected, the product remains in the back mold, and the second-color product is injected after the back mold rotates to obtain a complete two-color product. However, the two-color mold often has the phenomenon that the first-color product loosens or falls off when the subsequent mold is rotated, resulting in defective second-color products or mold crushing. Therefore, it is necessary to design a two-color mold that can effectively prevent the product from falling off. Contents of the invention [0003] The object of the present invention is to provide a two-color mold that prevents the product from falling off. Its structure is reasonable, which effectively solves the problem that the one-shot product is easy to fall off when the mold rotates, thereby i...
