Description

Technical Field

[0001] This utility model specifically relates to an injection blow mold with an improved air blowing mechanism, belonging to the field of injection blow mold technology. Background Technology

[0002] Injection blow molding is a molding process in the field of materials engineering for manufacturing hollow plastic products. The production of the product is completed through three stages: injection molding of the preform, blow molding, and cooling and demolding. It mainly uses three-station or four-station special equipment to achieve automated production. The process uses a mandrel transfer device to transfer the preform and uses a mold temperature control system to maintain the curing temperature of the preform.

[0003] According to application number 202122870899.0, which relates to the field of injection blow molding technology, specifically, it relates to an injection blow mold with an improved blowing mechanism, including a base plate, a hydraulic cylinder installed in a slot, a movable mold above the base plate, a first clamping plate inside the movable mold, the first clamping plate being connected to the movable mold via a first spring, a fixed mold near the right end of the upper surface of the base plate, a second clamping plate inside the fixed mold, the second clamping plate being connected to the fixed mold via a second spring, and an air injection pipe embedded on the upper surface of the fixed mold; in this injection blow mold with an improved blowing mechanism, the movable mold and the fixed mold are stably engaged by the insertion and cooperation of a fixed ring and an annular groove, enabling corresponding injection blow molding and mold closing. With the cooperation of the hydraulic cylinder, the movable mold is quickly and stably pushed; the first clamping plate, with the cooperation of the first spring, and the second clamping plate, with the cooperation of the second spring, facilitate rapid demolding; and with the cooperation of the air injection pipe, it is used for hollow blow molding.

[0004] The above-mentioned solution still has certain shortcomings in actual use; the spring of the above-mentioned device lacks the necessary limiting structure, which makes it significantly limited in injection molding. It can only support the production of specific mold models. When facing molds of different specifications, it is necessary to replace the whole machine to meet the requirements, which directly affects the stability and applicability of the device in actual application. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing an injection mold with an improved air blowing mechanism, comprising two sealing shells, an air blowing assembly installed between the two sealing shells, the air blowing assembly including a groove formed on the outer surface of the sealing shell, an installation frame installed between the two grooves, a bent pipe connected to the outer surface of the installation frame, and a connector installed at the other end of the bent pipe.

[0006] Furthermore, the air blowing assembly also includes a set of connecting seats respectively installed on the outer surface of the sealing shell, and bolts are threaded between the connecting seats, with a nut threaded onto the outer surface of each bolt.

[0007] Furthermore, the air blowing assembly also includes a screw barrel, which is rotatably connected to the outer surface of the sealing shell, and a screw is threadedly connected to the outer surface of the screw barrel.

[0008] Furthermore, each of the two screws has a movable plate fixedly connected to one end of each screw that is close to the other, and the movable plate is made of stainless steel.

[0009] Furthermore, a connecting ring is fixedly connected to the outer surface of each of the two screw cylinders, and a connecting rod is fixedly connected to the outer surface of each of the two connecting rings.

[0010] Furthermore, the air blowing assembly also includes a block mounted on the outer surface of the sealing shell, and a bell body is mounted on the bottom surface of the block.

[0011] Beneficial effects:

[0012] By combining the sealed housing with the air blowing assembly, the air blowing assembly can not only perform the injection blowing of raw materials, but also adjust the injection size according to the actual situation, thus eliminating the need to replace the entire machine and ensuring the stability and applicability of the device in actual use.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 As shown, an injection mold with an improved blowing mechanism includes two sealing shells 1. The two sealing shells 1 can store the raw materials, thereby facilitating subsequent processing operations by workers.

[0020] An air blowing assembly 2 is installed between the two sealing shells 1. The air blowing assembly 2 includes a groove 201 formed on the outer surface of the sealing shell 1. An installation frame 202 is installed between the two grooves 201. A bent pipe 203 is connected to the outer surface of the installation frame 202. A connector 204 is installed at the other end of the bent pipe 203. The installation frame 202 can be fixed by the connection between the installation frame 202 and the groove 201, thereby ensuring the performance of the bent pipe 203. At the same time, the connector 204 can be used to install with other structures, ensuring normal subsequent injection and blowing operations.

[0021] The air blowing assembly 2 further includes a set of connecting seats 205 respectively installed on the outer surface of the sealing shell 1, and bolts 206 are threadedly connected between the connecting seats 205. Each bolt 206 has a nut 207 threadedly connected to its outer surface. The air blowing assembly 2 also includes a screw barrel 208, which is rotatably connected to the outer surface of the sealing shell 1. A screw rod 209 is threadedly connected to the outer surface of the screw barrel 208. A movable plate 210 is fixedly connected to one end of each of the two screw rods 209 that are close to each other. The movable plate 210 is made of stainless steel. The outer surface of the cylinder 208 is fixedly connected with connecting rings 211, and the outer surface of the two connecting rings 211 is fixedly connected with connecting rods 212. The air blowing assembly 2 also includes a block 213 installed on the outer surface of the sealing shell 1. The bottom surface of the block 213 is equipped with a bell body 214. By rotating the cylinder 208, the screw 209 can be extended, thereby enabling the movement of the moving plate 210. During the movement, the connecting rod 212 will collide with the bell body 214, thereby enabling the counting of the movement distance of the moving plate 210.

[0022] As a technical optimization of this utility model, when using this device for processing, the raw material is first added between the two sealing shells 1, and then the sealing shells 1 are closed by bolts 206 and nuts 207. Then, the adjustment is made according to the actual situation. During the adjustment process, the distance between the moving plates 210 can be adjusted by rotating the screw cylinder 208. Then the connecting rod 212 will collide with the bell body 214, thereby enabling the counting of the moving distance of the moving plates 210 and ensuring consistent production quality.
