Background technique
The design principle of general double-color mold, after the first color product is completed in injection molding, product stays in rear mold, after rear mold rotation
It is molded the second color product, can just obtain complete double-colored product.But double-color mold often will appear the first color product subsequent
There is a phenomenon where loosen or fall off, cause the second color product bad or mold is caused to weigh wounded when mould rotates.Therefore, it is necessary to design one
The double-color mold that kind can effectively prevent product to fall off.
Summary of the invention
The purpose of the present invention is to provide a kind of double-color mold for preventing product from falling off, structurally reasonable, effective solutions
One penetrates the problem of product is easy to fall off when rotating with rear mold, to improve product quality, reduces rejection rate.
To achieve the above object, the technical scheme is to design a kind of double-color molds for preventing product from falling off, including
One penetrates mould group and penetrates the two of mould group side positioned at one and penetrates mould group, and described one, which penetrates mould group and two, penetrates Mo Zu and be equipped with rear mold respectively, and two
A rear mode structure is identical, and the rear mold includes lower template and the lower mold core at the top of lower template；Described one penetrates mould group
Penetrate preceding mould equipped with corresponding with corresponding rear mold one, this one penetrate before mould include penetrating cope plate and penetrating cope plate bottom set on one
One penetrates upper mold core, and described one, which penetrates upper mold core and lower mold core, penetrates product with synthesis type one, this one is penetrated product and stay in lower mold core, described
Two, which penetrate mould group, penetrates preceding mould equipped with corresponding with corresponding rear mold two, this two penetrate before mould include two penetrating cope plate and penetrating upper mold set on two
The two of board bottom portion penetrate upper mold core, and described two, which penetrate upper mold core and lower mold core, penetrates product with synthesis type two, and the lower template is equipped with two
A sliding block, two sliding blocks are located at the two sides of lower mold core, and the sliding block is slidably connected to lower die by slide guide straight trough
The top of plate, direction of the slide guide straight trough for guide shoe towards or away from lower mold core are slided, the slot bottom of the slide guide straight trough
Equipped with mounting hole, which is located at side of the sliding block far from lower mold core, and output shaft upward perpendicular is equipped in the mounting hole
Oil cylinder is set, is connected with elevator on the output shaft of the oil cylinder, the inner wall of the elevator and mounting hole is slidably matched, and the elevator
Upper end be equipped with the first inclined-plane, first inclined-plane from top to bottom to lower mold core direction tilt, side of the sliding block far from lower mold core
Portion is equipped with the second inclined-plane corresponding with the first inclined-plane, and the inclined direction on second inclined-plane is consistent with the inclined direction on the first inclined-plane,
The sliding block is connected with reset spring and briquetting in the side close to lower mold core, and the reset spring is fixed in slide guide straight trough,
The briquetting is located at the top of slide guide straight trough, which penetrates product for pushing down one.
Preferably, the rotating mechanism that can be horizontally rotated is equipped between described two rear molds.
Preferably, the bottom of the sliding block is equipped with the wear-resistant block contacted with the slot bottom of slide guide straight trough.
Preferably, the bottom of the wear-resistant block is equipped with several lubricant holes, is filled with lubricant in each lubricant hole.
Preferably, the lubricant hole is vertically arranged, and the upper end of the lubricant hole is flaring structure, and the lubricant hole
