Description

Technical Field

[0001] The utility model relates to the field of blow molding machine molds, and particularly relates to a blow molding machine mold with rapid positioning. Background Art

[0002] Blow molding machines are increasingly widely used. The most common blow molding machine is a bottle blowing machine. The principle of the blow molding machine is to soften plastic particles into a liquid, and through a prepared mold such as a bottle blank, blow it into a bottle by means of a process. By inflating the softened thermoplastic parison, it is made to closely adhere to the cooling surface of the closed mold, and the inflated parison solidifies to form a hollow plastic product. However, in actual use, the mold will heat up due to heat conduction after continuous use, which makes the solidification rate of the parison after blow molding gradually slow down, thus reducing the production speed and being unfavorable for the mass production of production enterprises. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a blow molding machine mold with rapid positioning, which can effectively solve the problems in the background art.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A blow molding machine mold with rapid positioning includes a blow molding mold. The blow molding mold includes a first half mold and a second half mold. A cooling frame is arranged outside between the first half mold and the second half mold. At the middle of the ends of the second half mold away from each other, hydraulic rods are fixedly connected. The other ends of the hydraulic rods are fixedly connected with fixed frames, and the fixed frames are fixedly connected to both sides of the top of the workbench. At the corners of the ends of the first half mold and the second half mold away from each other, guide rods are fixedly connected. The other ends of the guide rods penetrate through and are slidably connected with the fixed frames. On the sides close to each other of the first half mold and the second half mold, a plurality of mold cavities are arranged. Inside the mold cavities, plastic bottles are arranged. At the tops of the plastic bottles, blow molding ports are connected. The blow molding ports are fixedly connected to the middle of the top of the hollow frame. At the corners of one side of the first half mold and the second half mold away from the hydraulic rods, positioning columns are fixedly connected. At the corners of the other side of the first half mold and the second half mold away from the hydraulic rods, positioning holes are opened, and the ends of the positioning columns are clamped inside the positioning holes.

[0006] Preferably, the cooling frame includes a hollow frame. At the front and rear parts inside the hollow frame, a plurality of air inlets are fixedly connected. The air inlets are all clamped inside the connection ports. On the sides close to each other of the connection ports, air inlet channels are opened. The other ends of the air inlet channels are all communicated with cooling cavities. At the bottoms of the cooling cavities, air outlet channels are opened. Inside the air outlet channels, air outlets are clamped, and the air outlets are fixedly connected to the bottom inside the hollow frame. At the middle of the connection between the first half mold and the second half mold, a communication channel is opened.

[0007] Preferably, the connection ports are all opened in the middle parts of the front and rear sides of the connection between the first half-mold and the second half-mold.

[0008] Preferably, the cooling cavities are all arranged outside the mold cavity.

[0009] Preferably, a plurality of air inlet pipes are fixedly connected to the rear end of the hollow frame.

[0010] Preferably, the cooling cavities on the front and rear sides are connected through a communication channel.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] After the plastic bottle is shaped, people can inject cooling gas into the hollow frame through the upper air inlet pipe. The cooling gas will enter the air inlet channel through the air inlet on the inner side of the hollow frame, and then can flow into the cooling cavity through the air inlet channel. The communication between the cooling cavities can be maintained through the communication channel, so that the cooling gas can fill the cooling cavity more evenly. The cooling gas in the cooling cavity can cool the mold cavity, thus effectively improving the curing speed of the plastic bottle in the mold cavity, improving the production efficiency of the plastic bottle. At the same time, due to thermal expansion and contraction, the mold cavity and the plastic bottle will shrink. Due to the different shrinkage ratios of different materials, gaps will appear between the mold cavity and the plastic bottle, and the two will separate, which is conducive to the subsequent mold opening and material taking operations and is beneficial to actual use. The cooling gas will be discharged from the cooling cavity through the air outlet channel and the air outlet, and discharged from the hollow frame through the lower air inlet pipe, realizing the recycling of the cooling gas.

[0019] As Figures 1-4 shown, a blow molding machine die with quick positioning includes a blow molding die 1. The blow molding die 1 includes a first half die 101 and a second half die 104. A cooling frame 2 is externally arranged between the first half die 101 and the second half die 104. Hydraulic rods 103 are fixedly connected to the middle parts of the ends of the second half die 104 away from each other. The other ends of the hydraulic rods 103 are fixedly connected to fixed frames 105. The fixed frames 105 are fixedly connected to both sides of the top end of the workbench 107. Guide rods 102 are fixedly connected to the corners of the ends of the first half die 101 and the second half die 104 away from each other. The other ends of the guide rods 102 penetrate and are slidably connected to the fixed frames 105. A plurality of mold cavities 108 are arranged on the sides of the first half die 101 and the second half die 104 close to each other. Plastic bottles 109 are arranged inside the mold cavities 108. Blowing ports 111 are connected to the tops of the plastic bottles 109. The blowing ports 111 are fixedly connected to the middle parts of the tops of the hollow frames 201. Positioning columns 106 are fixedly connected to the corners of the ends of one side of the first half die 101 and the second half die 104 away from the hydraulic rods 103. Positioning holes 110 are formed in the corners of the ends of the other side of the first half die 101 and the second half die 104 away from the hydraulic rods 103. The ends of the positioning columns 106 are engaged inside the positioning holes 110.

[0020] In this embodiment, the blow molding die 1 includes a second half die 104. A cooling frame 2 is disposed outside between the second half dies 104. At the middle of the ends of the second half dies 104 away from each other, hydraulic rods 103 are fixedly connected. The other ends of the hydraulic rods 103 are fixedly connected with fixing frames 105. The fixing frames 105 are fixedly connected to both sides of the top of the workbench 107. At the corners of the ends of the first half die 101 and the second half die 104 away from each other, guide rods 102 are fixedly connected. The other ends of the guide rods 102 penetrate through and are slidably connected with the fixing frames 105. On the sides of the first half die 101 and the second half die 104 close to each other, a plurality of mold cavities 108 are provided. Inside the mold cavities 108, plastic bottles 109 are provided. At the tops of the plastic bottles 109, blow molding ports 111 are connected. The blow molding ports 111 are fixedly connected to the middle of the top of the hollow frame 201. At the corners of the ends of one side of the first half die 101 and the second half die 104 away from the hydraulic rods 103, positioning columns 106 are fixedly connected. At the corners of the ends of the other side of the first half die 101 and the second half die 104 away from the hydraulic rods 103, positioning holes 110 are provided. The ends of the positioning columns 106 are engaged inside the positioning holes 110.

[0021] Specifically, when manufacturing a beverage bottle, people can first close the first half die 101 and the second half die 104 through the hydraulic rods 103, and place the manufactured plastic bottle blank 109 into the mold cavity 108. When opening and closing the mold, the guide rods 102 can guide the movement of the first half die 101 and the second half die 104, making the process of opening and closing the first half die 101 and the second half die 104 smoother. At the same time, the positioning columns 106 on the first half die 101 can correspond to the positioning holes 110 on the second half die 104 to position the first half die 101 and the second half die 104, so as to ensure that the mold cavities 108 on the first half die 101 and the second half die 104 can be more tightly sealed after closing the mold, which is beneficial to the subsequent blow molding work. When the first half die 101 and the second half die 104 are completely closed, people can start the blow molding machine. Through the blow molding ports 111, air can be blown into the plastic bottle blank 109. Through the mold cavities 108, the expansion range of the plastic bottle blank 109 can be restricted to realize the shaping work of the plastic bottle blank 109.

[0022] In this embodiment, the cooling frame 2 includes a hollow frame 201. A plurality of air inlets 202 are fixedly connected to the front and rear parts inside the hollow frame 201. The air inlets 202 are all engaged inside the connection ports 206. The connection ports 206 are all opened in the middle of the front and rear sides of the connection between the first half mold 101 and the second half mold 104. Air inlet channels 205 are opened on one side where the connection ports 206 are close to each other. The other ends of the air inlet channels 205 communicate with cooling cavities 209. The cooling cavities 209 are all arranged outside the mold cavity 108. Air outlet channels 208 are opened at the bottoms of the cooling cavities 209. Air outlets 204 are all engaged inside the air outlet channels 208. The air outlets 204 are all fixedly connected to the bottom inside the hollow frame 201. A plurality of air inlet pipes 203 are fixedly connected to the rear end of the hollow frame 201. A communication channel 207 is opened in the middle of the connection between the first half mold 101 and the second half mold 104. The front and rear cooling cavities 209 are connected through the communication channel 207.

[0023] Specifically, after the plastic bottle 109 is shaped, people can inject cooling gas into the inside of the hollow frame 201 through the upper air inlet pipe 203. The cooling gas will enter the air inlet channels 205 through the air inlets 202 inside the hollow frame 201, and thus can flow into the cooling cavities 209 through the air inlet channels 205. The communication between the cooling cavities 209 can be maintained through the communication channel 207, so that the cooling gas can fill the inside of the cooling cavities 209 more evenly. The cooling gas inside the cooling cavities 209 can cool the mold cavity 108, thereby effectively improving the curing speed of the plastic bottle 109 inside the mold cavity 108, and thus improving the production efficiency of the plastic bottle 109. At the same time, due to thermal expansion and contraction, the mold cavity 108 and the plastic bottle 109 will shrink. Due to the different shrinkage ratios of different materials, gaps will appear between the mold cavity 108 and the plastic bottle 109, and the two will separate, which is conducive to the subsequent mold opening, mold closing and material taking operations and is beneficial to actual use. The cooling gas will be discharged from the inside of the cooling cavities 209 through the air outlet channels 208 and the air outlets 204, and discharged from the hollow frame 201 through the lower air inlet pipe 203, realizing the recycling of the cooling gas.

[0024] Working principle:

[0025] People can first close the half mold one 101 and the half mold two 104 through the hydraulic rod 103, and place the fabricated plastic bottle preform 109 into the mold cavity 108. When opening and closing the mold, the guide rod 102 can guide the movement of the half mold one 101 and the half mold two 104, making the process of opening and closing the half mold one 101 and the half mold two 104 smoother. At the same time, the positioning posts 106 on the half mold one 101 can correspond to the positioning holes 110 on the half mold two 104 to achieve the positioning of the half mold one 101 and the half mold two 104, so as to ensure that the mold cavities 108 on the half mold one 101 and the half mold two 104 can be more tightly sealed after mold closing, which is beneficial to the subsequent blow molding work. When the half mold one 101 and the half mold two 104 are completely closed, people can start the blow molding machine, and blow air into the plastic bottle preform 109 through the blow molding port 111. The mold cavity 108 can limit the expansion range of the plastic bottle preform 109 to achieve the shaping work of the plastic bottle preform 109. At the same time, when the plastic bottle 109 is shaped, people can inject cooling gas into the hollow frame 201 through the upper intake pipe 203. The cooling gas will enter the intake hole channel 205 through the intake port 202 on the inner side of the hollow frame 201, and thus can flow into the cooling cavity 209 through the intake hole channel 205. The communication hole channel 207 can maintain the connection between the cooling cavities 209, making the cooling gas more evenly fill the inside of the cooling cavity 209. The cooling gas inside the cooling cavity 209 can cool the mold cavity 108, thereby effectively improving the curing speed of the plastic bottle 109 inside the mold cavity 108, and thus improving the production efficiency of the plastic bottle 109. At the same time, due to thermal expansion and contraction, the mold cavity 108 and the plastic bottle 109 will contract. Due to the different shrinkage ratios of different materials, gaps will appear between the mold cavity 108 and the plastic bottle 109, and the two will separate, which is beneficial to the subsequent mold opening and closing and material taking work and is beneficial to practical use.
