Problems solved by technology

[0005] The purpose of the present invention is to overcome that in the prior art, when forming and manufacturing thin parts, it is necessary to cut the nozzle material of the product after demoulding, which may easily cause deformation or cracks of the product during cutting, thereby increasing the reject rate, and provides a The mold structure with built-in cylinder can remove the nozzle material before the product is demoulded. Since the structure of the product is limited by the molding cavity before the product is demoulded, no deformation will occur during the removal

Embodiment 1

[0023] Example one, as Figure 1-4As shown, a mold structure with a built-in cylinder is used for forming annular sheet parts, including a mold base 1, an upper mold 2 and a lower mold 3, and a first ejector mechanism 4 and a lower mold are installed between the mold base and the lower mold. The second ejector seat 5 is located above the first ejector mechanism; the mold seat is provided with a horizontally movable moving block 6 and a driving cylinder 7 for controlling the movement of the moving block, and a lower part of the mold seat is provided with Main ejector rod 8; the moving block includes a vertical moving block 61 and a horizontal moving block 62 that are fitted with each other, the front and rear sides of the vertical moving block are provided with vertical moving grooves, and the horizontal moving block is There is a clamping part adapted to be clamped in the moving groove, the vertical moving block is facing up and down with the main ejector rod, the horizontal m...

Embodiment 2

[0025] Example two, as Figure 5 As shown, the difference between this embodiment and the first embodiment lies in the structure of the moving block. In this embodiment, the moving block includes an outer moving block 63, and the gas rod of the air cylinder is connected to the outer moving block. The middle of the outer moving block is provided with a perforation that penetrates up and down, and the inner moving block 64 is fitted and installed in the through hole.

Abstract

The invention discloses a mold structure with a built-in cylinder, belonging to a precision part mold, comprising a mold base, an upper mold and a lower mold, a first ejector mechanism and a second ejector mechanism; the first ejector mechanism includes a first ejector mechanism. The ejector seat, the nozzle cutter is fixedly installed on the first ejector seat, the product ejector rod is fixedly installed on the second ejector seat, and the first ejector seat is provided with a vertical ejection hole , a moving block and a driving cylinder that can move horizontally are arranged in the die base, a main ejector rod is arranged below the mold base, and the main ejector rod is arranged coaxially with the ejection hole; when the moving block When the ejector hole is blocked, the nozzle cutter installed on the first ejector seat can cut the nozzle material; and when the moving block is moved away, the main ejector rod can pass through the ejector hole to complete the process. The demoulding of the product solves the problem that the product is easily deformed when the nozzle material is cut in the prior art.

Description

technical field [0001] The invention relates to a mold for precision parts, in particular to a mold structure with a built-in cylinder. Background technique [0002] In the process of forming parts through the mold, it is necessary to inject liquid material into the molding cavity of the mold through the nozzle. When the molding is completed, the nozzle material with the same shape as the nozzle will be formed on the product. The nozzle material does not belong to the product itself. structure, so the nozzle material needs to be removed from the product. [0003] In the old technology, the nozzle material is generally removed after the part is demolded, which increases the number of stations in the assembly line, resulting in increased production and transportation costs. In addition, after the part is demolded, its structure loses its support. In the process of nozzle material, it is easy to cause deformation of the part itself, or cracks on the surface of the part, especi...
