[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] Reference Figure 1~Figure 5 , Figure 7 , Figure 8 , Fig.10 and Fig.11 The filter bottle injection mold comprises an ejector plate 1, an ejector 2, a front mold circular insert pin 3, a rear mold circular insert pin 4, a cooling pipe 5, and a panel 6, a nozzle plate 7, a front mold plate 8, a rear mold plate 9, a support plate 10, a square iron block 20 and a bottom plate 30 which are arranged in sequence from top to bottom.

[0039] A front mold core 40 is fixed below the front template 8, and a rear mold core 50 is fixed above the rear template 9. The front mold core 40 and the rear mold core 50 are arranged opposite to each other to form a cavity. In the actual injection molding process, the filter bottle is injection molded in the cavity.

[0040] The front mold core 40 is fixed with a front mold circular inlay pin 3, one end of the rear mold circular inlay pin 4 is fixed on the carrier plate 10, and the other end penetrates the rear mold plate 9 and the rear mold core 50 and then extends into the mold cavity, and cooperates with the front mold circular inlay pin 3. Among them, the rear mold circular inlay pin 4 is conical, and the outer diameter of the top end is smaller than the outer diameter of the bottom end. When the filter bottle injection mold is closed, the top end of the rear mold circular inlay pin 4 extends into the front mold core 40 and abuts and cooperates with the bottom end of the front mold circular inlay pin 3; the bottom end of the front mold core 40 cooperates with the top end of the rear mold core 50, which is convenient for the product to be injection molded in the corresponding space to obtain the corresponding product.

[0041] The ejector plate 1 is arranged on the inner side of the square iron block 20, one end of the ejector 2 is fixed on the ejector plate 1, and the other end can penetrate the rear mold circular inlay pin 4 and then extend out; therefore, after the product injection molding is completed, the ejector plate 1 can drive the ejector 2 to push it upward, thereby ejecting the product, separating the product from the rear mold circular inlay pin 4, and realizing product demolding.

[0042] The rear mold circular inlay pin 4 is a hollow structure, the cooling pipe 5 is located inside the rear mold circular inlay pin 4, and a water inlet 101 and a water outlet 102 are provided on the support plate 10. The water inlet 101 is connected to the water inlet end of the cooling pipe 5, and the water outlet 102 is connected to the water outlet end of the cooling pipe 5.

[0043] The cooling pipe 5 extends from the bottom of the rear mold circular pin 4 to the top of the rear mold circular pin 4. The cooling pipe 5 includes a water inlet pipe 51, a water outlet pipe 52 and a connecting pipe 53. The connecting pipe 53 is circular and located at the top of the water inlet pipe 51 and the water outlet pipe 52. The water inlet pipe 51 is connected to the water inlet 101 and spirals upward to the connecting pipe 53. The water outlet pipe 52 spirals downward from the connecting pipe 53 to the water outlet 102. Therefore, through the circular connecting pipe 53, it is convenient for water entering the water inlet pipe 51 to be connected to the water outlet pipe 52 through the connecting pipe 53, and flow to the water outlet 102 through the water outlet pipe 52.

[0044] In actual use, a water pipe is inserted at the water inlet 101 and connected to the bottom of the water inlet pipe 51; a water pipe is inserted at the water outlet 102 and connected to the bottom of the water outlet pipe 52, so as to facilitate the connection between the water inlet 101 and the water outlet 102 and the external structure. When the product needs to be cooled and shaped after injection molding, cooling water is introduced through the water inlet 101, and the cooling water flows upward from the bottom of the water inlet pipe 51 in a spiral; after flowing to the connecting pipe 53, it flows to the water outlet pipe 52, flows downward from the water outlet pipe 52 in a spiral, and finally flows out from the water outlet 102. Therefore, through the flow of cooling water in the cooling pipe 5, heat exchange can be carried out in the rear mold circular pin 4, and the heat in the rear mold circular pin 4 can be quickly taken away, which is convenient for the rapid cooling and shaping of the product injected on the rear mold circular pin 4; through the spiral flow of cooling water, the inner wall of the entire rear mold circular pin 4 can be easily dissipated evenly, which is convenient for uniform cooling of the product and prevents large differences in local cooling speed of the product, thereby ensuring the injection molding quality of the product and improving the product yield.

[0045] like Figure 1~Figure 5 and Fig. 9 As shown, an exhaust channel 501 is provided on the rear mold core 50, one end of the exhaust channel 501 is connected to the mold cavity, and the other end can penetrate the rear mold core 50, and the depth of the exhaust channel 501 is 0.5 mm. Therefore, the depth of the exhaust channel 501 is 0.5 mm, which can facilitate the discharge of air, and the injection molded colloid will not be squeezed out from the exhaust channel 501. The air in the mold cavity can be guided to the outside through the exhaust channel 501 to prevent the air from being squeezed into the product during injection molding. Specifically, when the product is injection molded in the mold cavity, the injection molded colloid is injected into the mold cavity, and the air in the mold cavity is discharged from the exhaust channel 501 at the bottom, thereby preventing the air from remaining in the product, avoiding the formation of bubbles on the product, and ensuring the injection molding quality of the product.

[0046] like Figure 3 and Figure 6 As shown, the filter bottle injection mold of the present invention also includes a slider assembly 60, which is located on both sides of the cavity. The slider assembly 60 includes a slider 601, a slider seat 602 and a shovel 603. One end of the shovel 603 is fixed to the panel 6, and the slider seat 602 cooperates with the shovel 603. One end of the slider 601 is fixed to the slider seat 602, and the other end penetrates the front mold core 40 and cooperates with the cavity. When the mold is closed, the slider 601 extends into the cavity and cooperates with the cavity, which facilitates the molding of the groove structure on the side of the filter bottle and meets the injection molding requirements of the product.

[0047] A cavity 81 is provided below the front template 8, the front mold core 40 is located in the cavity 81, the slider seat 602 is located in the cavity 81 and abuts against the top of the cavity 81, and a guide block 604 is provided at one end of the shovel 603, the guide block 604 is tilted, and the guide block 604 matches the slider seat 602. The guide block 604 and the shovel 603 are an integrally formed structure; the slider seat 602 is provided with a guide hole that matches the guide block 604.

[0048] An inclined surface 605 is provided on one side of the shovel 603. The inclined surface 605 is located above the guide block 604. The inclined direction of the inclined surface 605 is opposite to the inclined direction of the guide block 604. The guide block 604 has an inclined angle of 20°. The guide block 604 can act on the slider seat 602 to drive the slider seat 602 to move, thereby meeting the moving distance requirement of the slider 601. The inclined angle of the inclined surface 605 is 5°. Therefore, by providing the inclined surface 605, the shovel 603 can be better inserted into the front template 8 to play a guiding role.

[0049] Specifically, when the filter bottle injection mold of the present invention is in mold closing, the panel 6 drives the shovel 603 to move downward, the guide block 604 acts on the slider seat 602, pushes the slider seat 602 to move toward one side of the cavity, and the slider seat 602 drives the slider 601 to move toward one side of the cavity, so that the other end of the slider 601 passes through the front mold core 40 and cooperates with the cavity, thereby achieving mold closing of the slider 601. Conversely, when the mold is in mold opening, the panel 6 drives the shovel 603 to move upward, the guide block 604 is pulled upward, and the guide block 604 pulls the slider seat 602 to move away from the cavity, thereby driving the slider 601 to gradually separate from the cavity, that is, the slider 601 is separated from the product after injection molding, and the slider 601 is demolded.

[0050] By opening a cavity 81 below the front template 8, space can be provided for the installation of the slider seat 602 and the slider 601, and sufficient space can be provided for the movement of the two; at the same time, by opening the cavity 81, the weight of the entire front template 8 can be reduced, the material used in the front template 8 can be reduced, and it is beneficial to reduce the production cost of the mold.

[0051] In actual use, there may be multiple cavities, and therefore, there are multiple sliders 601 corresponding to the cavities, so as to improve the injection molding efficiency of the product.

[0052] like Figure 1 , Figure 3 and Figure 4 As shown, the filter bottle injection mold of the present invention further includes a push rod 70, one end of which is fixed on the ejector plate 1, and the other end of which can penetrate the carrier plate 10 and abut against the rear template 9. When the mold is in a mold-closing state, the lower end surface of the rear template 9 abuts against the upper end surface of the carrier plate 10, and at this time, the top end of the push rod 70 is flush with the upper end surface of the carrier plate 10.

[0053] The filter bottle injection mold of the present invention further includes a first spring 80, which is sleeved on the push rod 70, one end of which abuts against the support plate 10, and the other end of which abuts against the ejector plate 1. In order to facilitate the abutment and cooperation between the first spring 80 and the support plate 10, a corresponding spring installation groove is provided at the bottom end of the support plate 10, and the top end of the first spring 80 is installed in the spring installation groove, so as to facilitate the installation and positioning of the first spring 80.

[0054] When the ejector plate 1 moves upward, the ejector plate 1 drives the push rod 70 to move upward synchronously. At this time, the upper end surface of the push rod 70 extends out of the top of the carrier plate 10, and the push rod 70 pushes the rear template 9 to move upward. When the rear template 9 moves upward, the rear mold core 50 moves upward together with the rear template 9. Since the bottom end of the rear mold circular inlay pin 4 is fixed on the carrier plate 10, when the rear mold core 50 moves upward, the rear mold core 50 can push the product upward, so that the product is separated from the rear mold circular inlay pin 4, which is convenient for demoulding of the product.

[0055] When the ejector plate 1 moves upward, the first spring 80 is compressed; when the product is ejected, the first spring 80 rebounds, and under the action of the rebound force of the first spring 80, the ejector plate 1 can be pushed to move downward, thereby realizing the reset of the ejector plate 1.

[0056] like Figure 1~Figure 5As shown, the filter bottle injection mold of the present invention also includes a second spring 11, a first tie rod 12, a second tie rod 13, a sleeve 14 and a gasket 15. One end of the first tie rod 12 is fixed on the carrier plate 10, and the second tie rod 13 is T-shaped. The bottom end of the front template 8 is provided with a matching hole 82. The large end of the second tie rod 13 is located above the rear template 9 and can extend into the matching hole 82. The small end of the second tie rod 13 is fixed to the other end of the first tie rod 12. The rear template 9 is provided with a first mounting groove 91. The sleeve 14 is sleeved on the outside of the second tie rod 13. The second spring 11 is sleeved on the outside of the sleeve 14. The gasket 15 is sleeved on the small end of the second tie rod 13. One end of the second spring 11 abuts against the bottom end of the first mounting groove 91, and the other end abuts against the gasket 15. The sleeve 14 is provided to facilitate the sleeve of the second spring 11; the outer diameter of the gasket 15 is larger than the outer diameter of the second spring 11, so that the external force acts on the second spring 11 through the gasket 15.

[0057] In the actual installation process, the first tie rod 12 and the second tie rod 13 are both screw rods. In order to facilitate the fixation of the first tie rod 12 and the second tie rod 13, a groove is provided at the bottom end of the rear template 9, and a nut 17 is fixed in the groove. The first tie rod 12 and the second tie rod 13 are both fixed to the nut 17 by threaded connection, which facilitates the connection of the first tie rod 12 and the second tie rod 13. The large end of the first tie rod 12 is fixed on the carrier plate 10, and the small end is connected to the nut 17.

[0058] The gasket 15 is sleeved on the small end of the second pull rod 13 . Therefore, when the gasket 15 moves upward, the gasket 15 can be limited by the large end of the second pull rod 13 , thereby achieving the limitation of the second spring 11 .

[0059] When the rear template 9 moves upward under the pushing action of the push rod 70, the sleeve 14, the second spring 11 and the gasket 15 move upward, and when the gasket 15 moves to the large end of the second pull rod 13, the large end of the second pull rod 13 abuts against the gasket 15. At this time, the large end of the second pull rod 13 limits the gasket 15 and the second spring 11, and as the rear template 9 gradually rises, the second spring 11 is compressed under the joint action of the large end of the second pull rod 13 and the rear template 9. When the force of the push rod 70 on the rear template 9 is cancelled, the second spring 11 rebounds, and under the action of the rebound force of the second spring 11, the rear template 9 is pushed downward to move downward, so that the rear template 9 gradually approaches the carrier plate 10.

[0060] By providing the second spring 11, when the product is demoulded, the front mold core 40 and the rear mold core 50 can be separated by the rebound force of the second spring 11, which is convenient for demoulding the product later.

[0061] The filter bottle injection mold of the present invention further includes a third spring 16. A second mounting groove 83 is provided at the top of the front template 8. The third spring 16 is located in the second mounting groove 83. The top of the third spring 16 abuts against the nozzle plate 7. Therefore, after the product is injection molded in the cavity, the nozzle plate 7 can be bounced upward by the rebound force of the third spring 16, so that the nozzle plate 7 is separated from the front template 8, thereby realizing the separation of the nozzle from the front template 8.

[0062] The specific opening and closing process of the filter bottle injection mold of the present invention is as follows:

[0063] When closing the mold, the panel 6, the nozzle plate 7 and the front template 8 move toward the side of the rear template 9, so that the front mold core 40 matches with the rear mold core 50, and the rear template 9 is pressed against the carrier plate 10. At this time, the front mold circular insert pin 3 matches with the rear mold circular insert pin 4. When the panel 6, the nozzle plate 7 and the front template 8 move toward the side of the rear template 9, the panel 6 drives the shovel 603 to move downward, and under the action of the guide block 604, the slider seat 602 and the slider 601 are pushed toward the side of the cavity, so that the slider 601 matches with the cavity to achieve closing the mold.

[0064] When the mold is closed, the external injection colloid is injected into the mold cavity. When the injection colloid is injected, the gas in the mold cavity is squeezed out through the exhaust channel 501. After the injection of the injection colloid is completed, cooling water is injected from the water inlet 101, and the cooling water flows into the cooling pipe 5. The cooling water in the cooling pipe 5 performs heat exchange in the rear mold circular insert pin 4, so that the rear mold circular insert pin 4 can be quickly and evenly cooled, so that the product on the rear mold circular insert pin 4 can be quickly fixed, and the desired injection molded filter bottle (such as Fig.12 as shown).

[0065] After the injection molding of the filter bottle is completed, the product needs to be demoulded. Specifically, when the mold is opened, the external clamping force is removed, and the gate plate 7 is separated from the front template 8 under the rebound force of the third spring 16, so that the gate is separated from the injection molded product. Subsequently, the panel 6 and the gate plate 7 continue to move upward (i.e., away from the rear template 9). During the upward movement of the panel 6, the shovel 603 moves upward, so that the shovel 603 drives the slider 601 to separate from the cavity, so that the slider 601 is demoulded. Subsequently, the front template 8 moves upward, so that the front template 8 is separated from the rear template 9, so that the front mold round inlay 3 is separated from the product. After the front template 8 moves upward to its position, the ejector plate 1 moves upward. When the ejector plate 1 moves upward, it drives the ejector 2 and the push rod 70 to move upward. Under the action of the push rod 70, the rear template 9 is pushed upward. When the rear template 9 moves upward, it drives the rear mold core 50 to move upward together, so that the rear mold core 50 pushes the molded product upward, so that the product is gradually separated from the rear mold circular inlay pin 4, and combined with the ejector pin, the product is separated from the rear mold circular inlay pin 4, and the product is ejected to achieve product demolding.

[0066] When the ejector plate 1 moves upward, the first spring 80 is compressed; when the product is ejected, the ejector plate 1 is pushed back to its original position under the rebound force of the first spring 80 .

[0067] The above are only preferred embodiments of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
