Description

Technical Field

The lower molding surface 6 composed of the fixed insert 4 and the inclined top insert 5 can be used for injection molding of the lens body. After the injection molding of the lens product is completed, the composite inclined top demolding component 7 can drive the inclined top insert 5 to move obliquely to the inner side of the lower template when the mold is opened, so that the parting surface on the inclined top insert 5 and the lens product can be separated to prevent the parting surface from being damaged by excessive pulling force when the product is ejected.

[0028] Specifically, the composite sloping ejection assembly 7 includes a sloping driving block 8 horizontally arranged at the lower side of the fixed insert 4, the sloping driving block 8 is connected to the inner end of the sloping insert 5 through a push-pull slider structure 9, and a No. 1 driving rod mounting groove 10 is obliquely arranged on the sloping driving block 8. A No. 1 driving rod that can be inserted into the No. 1 driving rod mounting groove is obliquely fixed on the upper template. When the mold is opened, the upward movement of the upper template can drive the sloping driving block to move horizontally through the No. 1 driving rod, thereby driving the sloping insert 5 to move obliquely toward the inner side of the lower template, so that the parting surface on the sloping insert 5 and the photometric mirror product are separated.

[0029] Specifically, the push-pull slider structure 9 includes push-pull slots 11 arranged on both sides of the inner end of the inclined top insert 5, and the inclined top driving block 8 is provided with two push-pull sliders 12 inserted into the push-pull slots 11. The movement of the inclined top driving block 8 can drive the push-pull sliders to move, and the movement of the push-pull sliders in conjunction with the push-pull slots can drive the inclined top insert 5 to move obliquely toward the inner side of the lower template.

[0030] Preferably, the push-pull slider 12 is connected to the tilting driving block 8 by a plurality of screws for easy disassembly.

[0031] Preferably, horizontal pressing plates 13 are provided on both sides of the inclined top driving block 8, and inclined pressing plates 14 are provided on both sides of the inclined top insert block 5. The horizontal pressing plates 13 can limit the inclined top driving block, and the inclined pressing plates can limit the inclined top insert block.

[0032] Specifically, two horizontal core pulling assemblies 15 are arranged on the side of the No. 1 color molding mechanism 3 away from the No. 1 color molding insert 2, and the two horizontal core pulling assemblies 15 are respectively against the fixed insert 4 and the inclined top insert 5, and the lower mold plate 1 is also provided with a side core pulling assembly 16 against the inclined top insert 5.

A second driving rod that can be inserted into the second driving rod slot is obliquely fixed on the upper mold plate, and when the upper mold plate moves upward, the second driving rod can drive the translation seat to translate away from the lower molding surface, thereby separating the horizontal core block from the product.

[0034] Specifically, the side core pulling assembly 16 includes a core pulling seat 20 and a linear drive 21 capable of driving the core pulling seat 20 to reciprocate in a straight line, and the core pulling seat 20 is fixedly connected with a side core block 22. The linear drive can drive the core pulling seat to move linearly away from the lower molding surface so as to separate the side core block from the product.

[0035] Those skilled in the art should understand that the linear drive may be an oil cylinder, an air cylinder or a linear motor, etc.

[0036] Specifically, a top plate 24 driven by two lifting drivers 23 is provided at the lower side of the lower template 1, and a plurality of straight ejector rods 25 are fixedly connected to the top plate 24, wherein some of the straight ejector rods 25 are fixedly connected to the top plate with straight ejector blocks 26, and a plurality of connecting slide grooves 27 corresponding to the straight ejector rods 25 are also provided on the inclined ejector drive block 8 and the inclined ejector insert block 5.

[0037] Those skilled in the art should understand that the lifting drive may be an oil cylinder, an air cylinder or a linear motor, etc.

[0038] The working principle of the utility model is as follows: the first color molding mechanism 3 can form a single-color lens body by injection molding, and the second color can be injected after the lens body is placed on the second color molding insert. The lower molding surface 6 composed of the fixed insert 4 and the inclined top insert 5 can be used for injection molding of the lens body. After the injection molding of the lens product is completed, the composite inclined top demoulding component 7 can drive the inclined top insert 5 to move obliquely to the inner side of the lower template when the mold is opened, so that the parting surface on the inclined top insert 5 and the lens product can be separated to prevent the parting surface from being damaged due to excessive pulling force when the product is ejected;

[0039] A No. 1 driving rod which can be inserted into the No. 1 driving rod installation groove is fixed obliquely on the upper template. When the mold is opened, the upper template moves upward and can drive the inclined top driving block to move horizontally through the No. 1 driving rod, thereby driving the inclined top insert 5 to move obliquely toward the inner side of the lower template, so that the parting surface on the inclined top insert 5 and the photometric mirror product are separated. The movement of the inclined top driving block 8 can drive the push-pull slider to move. The movement of the push-pull slider and the push-pull slide groove can drive the inclined top insert 5 to move obliquely toward the inner side of the lower template. The horizontal pressing plate 13 can limit the inclined top driving block, and the inclined pressing plate can limit the inclined top insert.

[0040] After the product is injection molded, the side core pulling assembly 16 can perform automatic core pulling. When the mold is opened, the two horizontal core pulling assemblies 15 can perform automatic core pulling. A No. 2 driving rod that can be inserted into the No. 2 driving rod slide groove is fixed on the upper template. When the upper template moves upward, the No. 2 driving rod can drive the translation seat to translate in the direction away from the lower molding surface, thereby separating the horizontal core block and the product. The linear drive can drive the core pulling seat to move linearly in the direction away from the lower molding surface, thereby separating the side core block and the product. The two lifting drives can act synchronously to drive the top plate to move vertically upward. The vertical upward movement of the top plate can drive the straight ejector rod to move upward. The straight ejector rod cooperates with the straight ejector block on the straight ejector rod to eject the product from the lower template.
