Description

Technical Field

[0001] The utility model relates to the technical field of plastic bottle embryo injection molding equipment, in particular to a plastic product injection molding device. Background Art

[0002] Injection molding is a method for producing industrial products. Products are usually produced by rubber injection molding and plastic injection molding. In the existing plastic preform injection molding device, when the preform is placed between two sets of templates, it is blown and molded by a blowing mechanism.

[0003] In the related art, a Chinese patent document with application number CN216443036U proposes a plastic bottle embryo injection molding device, which introduces cooling water into the water holes on the surfaces of the No. 1 template and the No. 2 template. The telescopic rod moves to make the No. 1 template and the No. 2 template approach each other, so that the sleeve rod squeezes and pushes the sealing plate to move, and the spring is stretched to seal the water hole. The cooling water is stored in the No. 1 template and the No. 2 template. The plastic bottle embryo is placed on the top of the cavity, and the blowing is achieved by using a blowing mechanism. The plastic bottle is formed in the cavity, and the telescopic rod moves to separate the No. 1 template and the No. 2 template, and the plastic bottle falls. When the plastic bottle is broken in the cavity due to quality problems, the threaded rod is rotated so that the threaded rod pushes the top of the bottom fragments of the plastic bottle upward.

[0004] With respect to the above-mentioned related technologies, the inventors believe that there are the following defects: the mold in the method is fixed, and during the long injection molding process, the inside of the mold will be contaminated with many impurities and need to be cleaned. Due to its fixed method, it is inconvenient for operators to disassemble and clean the inside of the mold, which increases the difficulty of cleaning and reduces the subsequent production quality of plastic bottles. In view of this, a plastic product injection molding device is proposed to solve the above problems. Utility Model Content

[0023] The mounting mechanism 5 includes a limiting groove 511, an insertion rod 502 and a clamping groove 510. A limiting groove 511 is provided on one side of the mold 3 and at the lower part thereof. A fixed box 501 is fixed in the U-shaped plate 7. The fixed box 501 is located in the limiting groove 511. Insertion rods 502 are provided at both ends of the fixed box 501. One end of the insertion rod 502 passes through the fixed box 501 and is slidably connected to the fixed box 501 to facilitate the staff to rotate the rotating shaft 506. A clamping groove 510 that is clamped with the insertion rod 502 is provided on the mold 3, and the clamping groove 510 is communicated with the limiting groove 511.

[0024] The device aligns the limiting groove 511 on the mold 3 with the fixing box 501 so that the fixing box 501 is located in the limiting groove 511, and then the mold 3 is limited and fixed by engaging the insert rod 502 with the clamping groove 510.

[0025] The mounting mechanism 5 further comprises a rotating shaft 506 , and the rotating shaft 506 is rotatably mounted in the fixed box 501 . One end of the insertion rod 502 penetrates through the U-shaped plate 7 and is slidably connected thereto.

[0026] A turntable 507 is fixed on the rotating shaft 506, and ropes 508 are wound around both sides of the turntable 507. Two fixed plates 505 are fixed in the fixed box 501, and two slide plates 503 are slidably installed in the fixed box 501.

[0028] By rotating the rotating shaft 506, the rotating shaft 506 drives the rotating disk 507 to rotate, the rotating disk 507 pulls the ropes 508 on both sides to move, and then the slide plate 503 is pulled by the ropes 508, the slide plate 503 squeezes the spring 504, and then the slide plate 503 drives the insertion rod 502 to move into the fixed box 501, and then the mold 3 can be disassembled.

[0031] On the contrary, the spring 504 can be used to extend and retract to drive the insert rod 502 to move into the slot 510 to limit and fix the mold 3.

[0032] When the mold 3 needs to be blow-molded, the two cylinders 4 are started to drive the U-shaped plate 7 on the movable plate 2 to move, and then the U-shaped plate 7 drives the mold 3 above it to move relatively. After the molds 3 on both sides are tightly fitted, the blowing mechanism 6 then blows the plastic bottle into shape.
