Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1-4, an injection mold for secondary ejection in a pitched roof movement comprises a front mold plate 1, a rear mold plate 2 and a pitched roof structure 3, wherein the rear mold plate 2 is arranged below the front mold plate 1, a front mold core 4 is arranged in the middle of the lower end of the front mold plate 1, and a rear mold core 5 is arranged in the middle of the upper end of the rear mold plate 2. When the front template 1 and the rear template 2 are matched, the front mold core 4 and the rear mold core 5 are mutually attached, a molding cavity 6 is formed in the gap part of the front mold core 4 and the rear mold core 5, and the shape and the size of the molding cavity 6 are the same as those of a product to be manufactured. The rear die plate 2 and the rear die core 5 are internally and jointly formed with a chute 7, and the pitched roof structure 3 is installed in the chute 7. Specifically, the pitched roof structure 3 comprises a large pitched roof 31, a roof block 32, a pitched roof guide block 33 and a pitched roof base 34. The large inclined top 31 is arranged in the chute 7, the top block 32 is arranged in the large inclined top 31 and is close to the upper end face of the large inclined top 31, the top block 32 is horizontally limited in the large inclined top 31, the top block 32 is connected with the large inclined top 31 through a spring 35, the top block 32 can horizontally move relative to the large inclined top 31, one end of the top block 32 is a top end 321, the top end 321 is used for ejecting the product in a back-off mode, the other end of the top block 32 is in contact with the rear mold core 5, when the large inclined top 31 slides along the chute 7, the top block 32 is subjected to the acting force of the spring 35 and the rear mold core 5, so that the top block 32 vertically moves relative to the rear mold core 5, and the top block 32 horizontally moves relative to the large inclined top 31; the large pitched roof 31 is obliquely connected with a pitched roof guide block 33, the inclination angle of the large pitched roof 31 is consistent with that of the chute 7, the pitched roof guide block 33 is fixed in the rear template 2, and the large pitched roof 31 can obliquely slide along the pitched roof guide block 33 and the chute 7; the inclined top base 34 is connected to the lower end of the large inclined top 31, the inclined top base 34 and the large inclined top 31 are connected through a transverse sliding chute structure 36, and when the large inclined top 31 slides along the inclined chute 7 in an inclined mode, the inclined top base 34 moves synchronously with the large inclined top 31 in the vertical direction and slides relatively in the horizontal direction. An ejector plate is arranged in the rear template 2, the lower end of the inclined ejector base 34 is fixedly connected with the ejector plate, the injection mold exerts acting force on the ejector plate to drive the inclined ejector base 34 to move up and down, the ejector plate comprises an ejector pin panel 8 and an ejector pin base plate 9, and the ejector pin panel 8 is arranged on the ejector pin base plate 9.

Wherein, still be equipped with back mould position 10 and the position mold insert 11 of going of back mould between front template 1 and the back template 2, the position mold insert 11 of going of back mould is connected to back mould position 10 of going, and the position mold insert 11 of going of back mould 10 and the cooperation of the position mold insert 11 of going of back mould front mould benevolence 4 and the forming cavity 6 of back mould benevolence 5 form for form the hole site structure of product during injection moulding.

Wherein, be connected with spacing post 12 at the up end of thimble board, spacing post 12 restriction thimble board rebound's distance avoids the excessive ejecting of oblique top structure 3.

As shown in fig. 3, after the injection mold completes injection molding, the mold needs to be opened to eject the product, and at this time, the ejection end 321 of the ejector block 32 is located inside the large lifter 31 and is not ejected outwards. The rear mould slide 10 and the rear mould slide insert 11 in the injection mould are firstly withdrawn outwards, then the ejector plate drives the pitched roof base 34 to move upwards, and the large pitched roof 31 is acted by the pitched roof base 34 to slide upwards along the inclined directions of the pitched roof guide block 33 and the inclined groove 7. When the top block 32 slides upwards along with the large inclined top 31, the top block 32 is supported by the spring 35 and the rear mold core 5, moves vertically upwards, and finally moves to the state shown in fig. 4, the ejection end 321 of the top block 32 moves outwards to eject the reverse buckle of the product, and demolding of the product with the reverse buckle is completed smoothly. When returning from fig. 4 to the state of fig. 3, the top block 32 keeps moving vertically downward under the reaction force of the compressed spring 35, and the ejection end 321 of the top block 32 retracts into the large pitched roof 31, completing the reverse movement of the pitched roof structure 3.

The above embodiments are merely illustrative and not restrictive, and all equivalent changes and modifications made by the methods described in the claims are intended to be included within the scope of the present invention.
