Description

Technical Field

[0001] This utility model relates to the field of bottle preform molding technology, and in particular to a high-precision molding cavity. Background Technology

[0002] In the production of plastic bottles, the bottle body needs to be shaped using a blow molding die. Molded plastic is poured into the die, and then the bottle is formed using a molding cavity. The molding cavity is typically mounted on a machine to work with the die. Most existing molding cavities consist of a molding body, a molding positioning cap, and a molding positioning base plate. The molding body is fixed to the machine by sequentially mounting the molding positioning cap and base plate onto it. This process is cumbersome, and the molding positioning cap and base plate are locked to the molding body using screws. Because this locking process uses a layered locking mechanism, there is a high probability of significant accuracy errors. Therefore, improvements are needed. Utility Model Content

[0004] To achieve the above objectives, this utility model proposes a high-precision molding cavity, including a molding body and a molding positioning cover. The lower end of the molding body is provided with a positioning base plate, and the molding positioning cover is cylindrical. A connecting hole is provided in the middle of the molding positioning cover, and a positioning hole is provided on the outer side of the molding positioning cover. The molding positioning cover is connected to the molding body through the connecting hole, and the molding positioning cover is locked to the molding body by external fixing screws cooperating with the positioning hole.

[0005] Specifically, the positioning base plate is integrally formed with the shaping body, the positioning base plate is provided with a number of fixing holes, the lower end of the shaping body is provided with a connection port, the positioning base plate is located above the connection port, and the shaping body is connected to the external machine through the fixing holes provided on the positioning plate.

[0006] Specifically, the positioning cover includes a main positioning cover and an auxiliary positioning cover, which are integrally formed. The auxiliary positioning cover is located inside the main positioning cover, and both the main positioning cover and the auxiliary positioning cover are provided with the positioning hole.

[0007] Specifically, the positioning hole includes a main hole and an auxiliary hole, with the main hole located on the main positioning cover and the auxiliary hole located on the auxiliary positioning cover.

[0008] Specifically, the lower end of the shaping and positioning cover is provided with a clearance groove.

[0009] Specifically, the shaping body is made of stainless steel.

[0010] This utility model's technical solution involves setting a positioning base on the shaping body to facilitate the connection between the shaping body and the machine. Simultaneously, a connecting hole is provided on the shaping positioning cover to allow it to be fitted onto the shaping body. Furthermore, a locking screw, located in the positioning hole on the shaping positioning cover, ensures precise locking between the shaping positioning cover and the shaping body, thereby improving the processing accuracy of the shaping body during use.
