Description
Technical Field
The utility model relates to a mould production technical field especially relates to a supplementary oblique top guiding mechanism of synchronous liftout formula.
Background
When a product is processed by a mold, due to the special shape of the product or the requirement in mass production, if the product is still in a mold cavity or cannot fall off by itself after one-time ejection, one-time ejection action needs to be added, and the design of the ejection action is called secondary ejection. The mold used for the special structure of the bumper or the deflector is usually a two-shot design. The general structure of the die is that a large cap presses a large inclined top, and the large cap is provided with a small inclined top, the small inclined tops on the large cap synchronously move with the large cap when the die is ejected for the first time, cannot be released from the large cap, and independently move to release from the large cap when the die is ejected for the second time. The link rod of the small pitched roof is obliquely arranged, and the ejection of the die is vertical movement, so that enough clearance space must be reserved on the plate B penetrating the link rod of the small pitched roof to ensure the running path of the link rod, and further ensure the smooth movement of the whole device. On one hand, the clearance causes poor support stability of the small pitched roof, and on the other hand, the clearance can not be used for installing and fixing a guide block (the guide block can limit the operation of a connecting rod), so that the guidance performance of the small pitched roof is weakened. Along with the gradual increase of the ejection height of the small pitched roof, the suspension length of the connecting rod is increased, the longer the suspension length is, the worse the stability is, the resetting is not smooth, or the resetting cannot be performed to the bottom, even the small pitched roof is stuck and broken, and particularly when the angle of the pitched roof is too large (the inclination degree of the connecting rod of the small pitched roof is large), the situation is particularly serious. Although the conventional method adopts a small pitched roof connecting rod with a small pitched roof angle and a large diameter, the problem of unsmooth pitched roof ejection and resetting can be caused, so that the top block print of a product is caused, the appearance of the product is seriously influenced, particularly, the quality of the pitched roof is increased along with the increase of a thickened connecting rod, and the stress stability of the pitched roof is poorer.

Further, the second ejector plate 3 is fixedly connected with an inclined ejector seat 31, the first ejector plate 2 is provided with an accommodating groove 21 matched with the inclined ejector seat 31, the inclined ejector seat 31 is located in the accommodating groove 21, an empty-avoiding chute 32 is arranged in the inclined ejector seat 31, and the second end 92 of the inclined ejector connecting rod 9 is connected in the empty-avoiding chute 32 in a sliding manner.
Further, the ejector pin mechanism further comprises a large cap link 71, and the large cap 7 is fixedly connected with the first ejector plate 2 through the large cap link 71.
Further, the B plate 4 is provided with a clearance area 41a for clearance of the pitched roof link rod 9.
Further, the pitched roof connecting rod 9 comprises two supporting rods which are arranged in parallel, the supporting rods are of hollow structures with openings at two ends, a through groove is formed in the small pitched roof 8, and the hollow structures are communicated with the through groove to form a water flow channel. The utility model provides a pentroof link 9 is including two links that set up side by side, every link is both ends open-ended hollow structure, because the mould production goods individual in-process needs cool off the mould, therefore, can follow the opening part input cooling water of one of them link second end 92 department, cooling water loops through link hollow structure and through the logical groove in the little pentroof 8 of opening circulation of first end 91, then the opening of another link first end 91, another link hollow structure of circulation exports through second end 92 opening, thereby form a cooling cycle, reach the result to the mould cooling.
Further, a first inserting channel 72 is arranged in the large cap 7, a first guide sleeve 721 is arranged in the first inserting channel 72, a second inserting channel 44 is arranged in the sliding guide block 42, a second guide sleeve 441 is arranged in the second inserting channel 44, and the first guide sleeve 721 and the second guide sleeve 441 are sequentially inserted into the link rod.
