[0023] like Figure 1-2 As shown, a demoulding mechanism of a straw forming mold is provided, wherein the forming mold is provided with a movable mold, and the movable mold is provided with a movable platen 10, a movable mold core 20 and a plurality of push rods 30, and the movable mold core 20 is provided with one or more cavities 21 adapted to the straw product 100; and further includes a side core pulling assembly 40 provided on the movable mold plate 10 and located beside the movable mold core 20, wherein:
[0024] Each cavity 21 is a semicircular groove arranged horizontally;
[0025] The side core pulling assembly 40 includes a horizontally arranged slide 50 extending in the same direction as the groove. The slide 50 is arranged above a plurality of push rods 30 and can leave the movable mold plate 10 in a vertical direction under the push of the push rods 30. A driving device 60 and a baffle 53 are arranged on the slide 50. The driving device 60 is transmission-connected to a slide seat 80 arranged on the slide 50 and can drive it to slide along the slide 50. The slide seat 80 is provided with more than one core 90 extending in the same direction as the groove. Each core 90 can pass through the baffle 53 and extend into or exit from a cavity 21 under the drive of the slide seat 80. The baffle 53 is arranged at the end of the slide 50 close to the cavity 21 and can prevent the straw product 100 from moving horizontally when each core 90 exits.
[0026] In this embodiment, a plurality of parallel grooves are provided on the side wall at one end of the straw product 100, and protrusions adapted to these grooves are formed on the inner wall of the cavity 21 of the movable mold core 20; when the mold is opened, these protrusions will pull the straw product 100 against the cavity of the movable mold core 20.
[0027] During demolding, the movable mold moves away from the fixed mold, and the straw product 100 is embedded in the cavity 21; the push rod 30 moves toward the movable mold plate 10 under the push of the driving mechanism on the movable mold and lifts the slide 50 to separate from the movable mold plate 10, and the slide 50 drives the slide 80, the core 90 and the driving device 60 to leave the movable mold plate 10 together, and the core 90 drives the straw product 100 sleeved on its periphery to separate from the movable mold core 20; the driving device 60 drives the slide 80 to slide on the slide 50 and drives the core 90 to retreat, and the straw product 100 is blocked by the retaining ring 70 and cannot move horizontally, and the core 90 escapes from it; the straw product 100 loses support and falls down to complete demolding.
[0028] Specifically, Figure 2 As shown, the baffle plate 53 is provided with a plurality of first through holes 54 which are matched one by one with the core 90 and extend horizontally. The end of the baffle plate 53 facing the movable mold core 20 is also provided with a coaxial baffle ring 70 on the periphery of each first through hole 54. The other end of each baffle ring 70 extends to the end of a cavity 21 respectively.
[0029] In this embodiment, a positioning boss is formed on the side wall of the other end of the straw product 100, and one end of the retaining ring 70 extends into the end of the cavity 21, so that the boss structure can be formed in cooperation with the cavity 21 during molding, and can also support the straw product 100 to prevent it from moving when the core 90 is withdrawn.
[0030] Specifically, Figure 2 As shown, a positioning hole groove 12 and a plurality of second through holes 11 are set on the movable template 10, the positioning hole groove 12 matches the slideway 50, each second through hole 11 is adapted to the push rod 30 and penetrates the movable template 10 in the vertical direction; a guide sleeve 13 is coaxially provided on the outer periphery of each second through hole 11 at the bottom end of the movable template 10.
[0031] It can be understood that the positioning hole groove 12 facilitates the rapid and accurate assembly of the slideway 50 on the movable platen 10, and the guide sleeve 13 can protect the guide rod 30 and correct its moving direction.
[0032] Specifically, the driving device is a linear motion driving device.
[0033] Specifically, Figure 2-3 As shown, each core 90 is further provided with a blind hole 91, and each blind hole 91 is connected to a water cooling pipeline 1 provided on the slide 80, and the water cooling pipeline 1 is filled with circulating coolant; the water cooling pipeline 1 includes water holes 2 provided on the slide 80 and interconnected, a plurality of water holes 2 are connected to the cores 90 one by one and are sealed, and a plurality of water holes 2 are connected to the external water pipes 3 and are sealed; a mounting plate 81 is installed at the end of the slide 80 close to the movable mold core 20, and a plurality of cores 90 are installed on the mounting plate 81, and one end of each core 90 is sealed and connected to a water hole 2.
[0034] It is understandable that after the injection molding is completed, the temperature of the straw product 100 is relatively high and has not been completely solidified. During the core pulling, it is easy to adhere to the core 90 and be torn. The setting of the water cooling pipeline 1 can quickly cool the core 90 before the core pulling action after the injection molding is completed, thereby reducing the adhesion between the core 90 and the outer straw product 100, making it easier to perform the subsequent core pulling operation without damaging the straw product 100.
[0035] The utility model provides a slideway 50 which can be transmission-connected to the push rod 30 beside the movable mold core 20, and a slide seat 80 is slidably installed on the slideway 50, and a core 90 which can extend into the cavity 21 is provided on the slide seat 80. After the mold is opened, the straw product 100 can be firstly taken away from the cavity 21 by the core 90, and then the core 90 can be pulled out of the straw product 100. The demoulding efficiency is high, and no demoulding mark will be left on the straw product 100, thereby ensuring the quality of the straw product 100. By providing a blind hole 91 in the core 90 and connecting it to the water-cooling pipeline 1, the core 90 can be condensed before core pulling, thereby reducing the adhesion between the core 90 and the peripheral straw product 100, avoiding or slowing down the pulling of the straw product 100 during the core pulling operation, thereby ensuring the product quality.
[0036] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
