Description

Technical Field

[0001] The utility model relates to the technical field of molding machines, in particular to multi-station injection-blowing hollow molding equipment. Background Art

[0002] Multi-station injection blow molding equipment is a highly efficient automated production equipment, mainly used to produce hollow plastic products, such as beverage bottles, detergent bottles, oil bottles, etc. This equipment integrates multiple stations and can complete the injection, stretching, blow molding and demoulding of plastic bottles in a continuous production process, greatly improving production efficiency and product quality.

[0003] In order to enhance the aesthetics of existing bottles, a mold with a specific shape of bumps or other structures may be set in the mold cavity. These designs can provide bottles with unique textures, patterns or shapes to meet the market demand for product appearance. However, during the blow molding process, these designs also bring some problems. In order to reduce the sticking phenomenon, it is usually necessary to spray a release agent on the mold surface. Since the bumps and other structures inside the mold increase the concavity of the inner wall of the mold, the release agent cannot be effectively applied evenly, which may cause some areas to still be prone to sticking. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-station injection blow molding device to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A multi-station injection blow molding device comprises a multi-station injection blow molding mechanism, wherein the multi-station injection blow molding mechanism comprises a chassis, and an anti-sticking mold mechanism is fixedly connected to a bottom wall of the chassis near one side;

[0007] The anti-sticking mold mechanism includes two mold units, hydraulic rod 2 and two smearing units.

The outer wall of the module one is slidably plugged into the outer wall of the T-shaped frame. The inner bottom wall of the chassis is located on the other two sides of the two mold units and is fixedly connected to a fixed seat. A hydraulic rod 1 is fixedly connected between the outer wall of the fixed seat and the mold unit.

[0008] Furthermore, the inner wall of the mold unit is provided with a plurality of arc grooves at equal intervals, the inner wall of the mold unit is provided with two square grooves at equal angles around the axis thereof at the arc grooves, and an arc frame is slidably inserted inside the square grooves or the arc grooves.

[0009] Preferably, a square hole is provided inside the module 1 on the inner wall of one side of the square groove, a slide rail 2 is slidably inserted inside the square hole, and an outer wall of the slide rail 2 is slidably inserted into the arc frame.

[0010] Preferably, the outer wall of the second hydraulic rod is fixedly connected to the inner wall of the chassis, the outer wall of one end of the second hydraulic rod is fixedly connected to the first slide rail, the outer wall of the first slide rail is slidably connected to two square plates, and the outer wall of the square plate is fixedly connected to the outer wall of the second slide rail.

[0011] Preferably, four modules 2 are fixedly connected at equal intervals near the center of the outer wall of the slide rail 1.

[0015] 1. Through the sliding connection between the two modules and the T-shaped frame, when the module is pushed, the two modules can be stably docked and closed. The stable sliding mold can ensure that it slides to the precise position on the fixed frame each time, ensuring the consistency of the processing process and the processing accuracy of the product, reducing product defects and improving product quality.

[0016] 2. By sliding and plugging the arc frame inside the square groove or arc groove, the position of the arc frame can be quickly adjusted according to work requirements.
