Problems solved by technology

At the same time, the torque deviation between the screw teeth is within 50gf.cm. Such an error accuracy requirement is already a high-end requirement. In addition to the complexity of the product's structure, the existing injection mold is difficult to meet such production accuracy requirements.

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as figure 1 , figure 2 In the shown embodiment, a side gate vertical runner and a plastic mold for side gates include a static mold 3 and a movable mold 1 located below the static mold 3, and a side of the movable mold 1 near the parting surface is provided with Die kernel 2, mold kernel 2 is provided with slide block 9, and slide block comprises first slide block 9a, second slide block 9b and the 3rd slide block 9c, static mold 3 is provided with the first slide block 9a, the second slide block The block 9b and the third slider 9c independently correspond to the inclined guide pillar 8 that drives the first slider 9a, the second slider 9b and the third slider 9c to slide outward when the movable mold 1 is away from the static mold 3 . The movable mold 1 is provided with a thimble 11 corresponding to the cavity 9d. The movable mo...

Abstract

The invention discloses an injection mold for side gate vertical runners and side gates. The injection mold comprises a static mold and a moving mold located below the static mold; a mold core is arranged on one side, close to the parting surface, of the moving mold; first sliding blocks, second sliding blocks and third sliding blocks which are arranged in T-shapes are arranged on the mold core; cavities are formed in the centers of combined positions of the first sliding blocks, the second sliding blocks and the third sliding blocks; the three side gate vertical runners and the side gates forcommunicating the side gate vertical runners with the waists of the cavities are formed among the adjacent surfaces of the first sliding blocks, the second sliding blocks and the third sliding blocks; and the static mold is provided with inclined guiding columns which correspond to the first sliding blocks, the second sliding blocks and the third sliding blocks independently and drive the first sliding blocks, the second sliding blocks and the third sliding blocks to slide towards the outer sides when the moving mold gets far away from the static mold. The invention aims to provide the injection mold which is used for the side gate vertical runners and the side gates, is used for filling lens cones evenly and guarantees the precision of the lens cones.

Description

technical field [0001] The invention belongs to the field of injection molds, in particular to a side gate vertical runner and a plastic mold for the side gate. Background technique [0002] With the popularity of 4K video, more and more 4K high-definition cameras are equipped on various devices. The core component of the 4K high-definition camera - the lens barrel, is the carrier for installing the lens. Due to the high space requirements on portable devices, the volume of 4K high-definition cameras is usually small, which puts forward high requirements for the design and production of lens barrels. Usually, the lens barrel of 4K high-definition camera products requires that the inner diameter error is within 0.0015mm, the roundness error is within 0.005mm, and the high axis is within 0.005mm. At the same time, the torque deviation between the screw teeth is within 50gf.cm. Such an error accuracy requirement is already a high-end requirement. In addition to the complexity...
