Description

Technical Field

[0001] This utility model belongs to the field of blow molding machine technology, specifically the optimized structure of cooling water channel for plastic bottle blow molding machine. Background Technology

[0002] A blow molding machine is a key piece of equipment used to manufacture hollow plastic products. It is widely used in packaging, chemical, pharmaceutical, food, and other industries. Using compressed air pressure, it inflates a heated and softened plastic preform and adheres it to the mold cavity wall. After cooling and solidification, the hollow product is obtained. As an important piece of equipment in the plastics processing field, the continuous technological advancement of blow molding machines has driven the development of various industries. From everyday consumer goods to industrial products, hollow plastic products produced by blow molding machines have permeated all aspects of people's lives. With changing market demands and technological innovation, blow molding machines will develop towards greater efficiency, intelligence, and environmental friendliness.

[0003] Meanwhile, a plastic bottle blow molding machine with announcement number CN219686537U is disclosed, including a machine body and a support frame, with the support frame installed at the top of the machine body; it also includes a moving device, a cooling device, a discharge pipe, an air blowing pipe, and two sets of molds. The discharge pipe is installed on the left side of the top of the support frame, and the air blowing pipe is installed on the right side of the top of the support frame. The two sets of molds are installed on the moving device in a front-to-back relative manner. The moving device is used to drive the two sets of molds to move back and forth relative to each other, and the moving device is also used to drive the two sets of molds to move left and right for adjustment. The cooling device is in contact with the two sets of molds and is used to cool the two sets of molds.

[0004] During the use of the aforementioned plastic bottle blow molding machine, the cooling device accumulates dirt and impurities over a long period of time. Because it is very difficult to clean the impurities inside the cooling device and the cooling device cannot be replaced, the cooling effect is affected, resulting in a decrease in work efficiency.

[0005] Therefore, an optimized structure for the cooling water channel of a plastic bottle blow molding machine is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background section, this invention provides an optimized cooling water channel structure for a plastic bottle blow molding machine, which has the advantages of making the cooling device easy to remove for cleaning and replacement, enabling precise heat dissipation and cooling, and increasing cooling efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an optimized cooling water channel structure for a plastic bottle blow molding machine, comprising a blow molding mold body, a square groove inside the blow molding mold body, a connecting plate fixedly installed inside the blow molding mold body, a second spring fixedly installed on the right side of the connecting plate, a limiting post fixedly installed on the right side of the second spring, a limiting groove opened above the limiting post, a limiting frame slidably installed inside the limiting post, and a fixing post fixedly installed on the right side of the limiting frame.

[0008] Preferably, a fixing block is fixedly provided below the fixing column, a spring is fixedly provided below the fixing block, a connecting column is fixedly provided below the fixing block, and a connecting column 2 is slidably provided inside the connecting column 1.

[0009] By adopting the above technical solution, spring one is set up. When the block is pressed down, spring one is compressed, causing connecting post one and connecting post two to descend. Spring one plays the role of buffering and resetting.

[0010] Preferably, a spring three is provided on the outside of the second connecting post, and the spring three is fixedly set with the first connecting post. An inclined ring is fixedly set on the outside of the second connecting post, and a limiting ring is slidably set on the outside of the second connecting post. A protective shell is fixedly set on the outside of the limiting ring, and the protective shell is fixedly set with the blow molding die body. The limiting post is slidably set inside the protective shell.

[0011] By adopting the above technical solution, a third spring is set up, which is fixedly connected to the inclined ring. When the block is pressed down, the second connecting post slides inside the first connecting post. The third spring acts as a connector. A protective shell is set up to protect the internal structure. A limiting ring is set up to determine the extension and retraction position of the second connecting post, and it stops when it touches the limiting ring.

[0012] Preferably, the inner spiral of the fixing column is provided with a threaded rod, and the threaded rod and the connecting column are arranged in a double spiral. The outer spiral of the threaded rod is provided with a fixing plate, and a block is fixed on the left side of the fixing plate.

[0013] By adopting the above technical solution, a threaded rod is set up to connect the fixing plate and the fixing column together, and then connect the block and the fixing column together. After the threaded rod is removed, the block pops out of the square groove for the replacement and cleaning of the cooling device.

[0014] Preferably, a spiral cooling water channel is fixedly provided inside the block, a square plate is fixedly provided on the front side of the block, an electric slide rail is fixedly provided inside the square plate, a slider is slidably provided inside the electric slide rail, a heat dissipation plate is fixedly provided on the rear side of the slider, and a heat absorption plate is fixedly provided on the rear side of the heat dissipation plate.

[0015] By adopting the above technical solution, a spiral cooling water channel is set up to increase the contact area and flow length between the coolant and the mold, thereby improving the cooling efficiency. An electric slide rail is set up so that the slider can slide in the electric slide rail, causing the heat dissipation plate and heat absorption plate to move up and down. The position of the heat absorption plate and heat dissipation plate is adjusted according to the thickness of the blow-molded plastic bottle, strengthening the cooling of the thicker parts of the bottle and reducing the cooling of the thinner parts, so as to achieve precise heat dissipation and cooling efficiency.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model, by setting spring two, allows the fixing plate on the block to contact the fixing post during installation, causing connecting post two to slide within connecting post one. The inclined ring then presses against the limiting post, causing the limiting post to extend and retract to the left under the action of spring two, allowing the inclined ring to pass over the limiting post. Simultaneously, the limiting frame slides in the limiting groove to prevent the limiting post from shifting. Next, rotating the threaded rod connects the fixing plate, fixing post, and connecting post two for fixation, securing the block in the square groove. When the block needs to be removed, rotating the threaded rod separates the fixing plate, fixing post, and connecting post two. The rebound of springs one and three causes the inclined ring to contact the inclined surface on the limiting post, restoring it to its original position, thus ejecting the block. This design makes the cooling device easy to remove for cleaning and replacement.

[0018] 2. This utility model improves cooling efficiency by setting up a spiral cooling water channel to increase the contact area and flow length between the coolant and the mold. It also features an electric slide rail, which allows the slider to slide and the heat dissipation plate and heat absorption plate to move up and down. The position of the heat absorption plate and heat dissipation plate is adjusted according to the thickness of the blow-molded plastic bottle, strengthening cooling in thicker areas and reducing cooling in thinner areas, thus achieving precise heat dissipation and increasing cooling efficiency.

The limiting is achieved by compression and limiting through the inclined ring 19. The column 13 extends to the left under the action of the second spring 12, causing the inclined ring 19 to pass over the column 13.

Then, the threaded rod 3 is rotated to connect the fixing plate 6, the fixing column 7, and the second connecting column 17 for fixation, fixing the block 4 in the square groove 2. When it is necessary to remove the block 4, the threaded rod 3 is rotated to separate the fixing plate 6, the fixing column 7, and the second connecting column 17. Through the rebound of the first spring 9 and the third spring 18, the inclined ring 19 contacts the inclined surface on the limiting column 13, restoring it to its original position, and then the block 4 is ejected. This design makes it easy to remove the cooling device for cleaning and replacement.

A spring 3 18 is provided on the outside of the connecting column 2 17, and the spring 3 18 is fixedly installed with the connecting column 16.

[0028] Working principle and process of optimized cooling water channel structure for plastic bottle blow molding machine:

[0029] When using the optimized cooling water channel structure of the plastic bottle blow molding machine, during the installation of block 4, the fixing plate 6 on block 4 contacts the fixing post 7, causing the connecting post 17 to slide in the connecting post 16. The inclined ring 19 presses against the limiting post 13, causing the limiting post 13 to extend and retract to the left under the action of the spring 12, allowing the inclined ring 19 to pass over the limiting post 13 and stop when it touches the limiting ring 20. Simultaneously, the limiting bracket 14 slides in the limiting groove 15 to prevent the limiting post 13 from shifting. Next, the threaded rod 3 is rotated to connect the fixing plate 6, the fixing post 7, and the connecting post 17 for fixation, thus fixing block 4 in the square groove 2. After installation, a spiral cooling water channel is set up for cooling. 5. To increase the contact area and flow length between the coolant and the mold, thereby improving cooling efficiency, an electric slide rail 22 is installed, allowing the slider 21 to slide within the electric slide rail 22, causing the heat dissipation plate 23 and the heat absorption plate 24 to move up and down. The positions of the heat absorption plate 24 and the heat dissipation plate 23 are adjusted according to the thickness of the blow-molded plastic bottle, strengthening cooling in thicker areas of the bottle and reducing cooling in thinner areas, thus achieving precise heat dissipation and increasing cooling efficiency. When it is necessary to remove the block 4, the threaded rod 3 is rotated to separate the fixing plate 6, the fixing post 7, and the connecting post 17. Through the rebound of the spring 1 9 and the spring 3 18, the inclined ring 19 contacts the inclined surface on the limiting post 13, restoring it to its original position, and then the block 4 is ejected.
