An adjustment structure, including a support plate, is provided on the lower surface of the base. The upper surface of the support plate is fixedly connected to the base, and a cylinder is fixedly connected to one side of the support plate.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figure 1 and Figure 2 The present invention provides a stabilizing and locking device for injection molds, comprising: a base 1, a lower mold 2 fixedly connected to the upper surface of the base 1, a plurality of columns 5 fixedly connected to the upper surface of the base 1, a top plate 6 fixedly connected to the upper end of the columns 5, a cylinder 7 fixedly connected to the upper surface of the top plate 6, an installation plate 8 fixedly connected to the output end of the cylinder 7, the installation plate 8 being slidably connected to the columns 5, an upper mold 9 fixedly connected to the lower surface of the installation plate 8, an injection hole 10 being provided on one side of the upper mold 9, two locking mechanisms 3 being provided on the upper surface of the base 1, and a sealing mechanism 4 being provided on the upper surface of the top plate 6.

[0033] In the embodiments of this utility model, please refer to Figure 3 and Figure 4The locking mechanism 3 includes a connecting cylinder 301. The lower end of the connecting cylinder 301 is fixedly connected to the upper surface of the base 1. The upper end of the connecting cylinder 301 is fixedly connected to the mounting cylinder 302. A connecting block 303 is slidably inserted inside the connecting cylinder 301. The connecting block 303 is configured as a frustum-shaped structure. A connecting rod 304 is fixedly connected to the upper surface of the connecting block 303. The upper end of the connecting rod 304 is fixedly connected to the lower surface of the mounting plate 8. Two rectangular holes 305 are opened in the inner wall of the mounting cylinder 302. A locking block 306 is slidably connected to the inner wall of the rectangular hole 305. The cross section of the locking block 306 is a right trapezoid. Two sliding rods 307 are slidably inserted through the outer wall of the mounting cylinder 302. One end of the sliding rod 307 is fixedly connected to the locking block 306. A spring 308 is sleeved on the arc surface of the sliding rod 307. The two ends of the spring 308 are fixedly connected to the locking block 306 and one side of the inner wall of the rectangular hole 305, respectively. By setting a locking mechanism 3, the upper mold 9 and lower mold 2 can be automatically locked after mold closing, which can prevent the mold from loosening due to factors such as equipment vibration, pressure fluctuation or operation error after mold closing, thereby improving the product molding accuracy and the working efficiency of the mold. The inclined waist side of the locking block 306 is rotatably connected to a pulley 315. When the connecting block 303 is inserted into the inner wall of the mounting cylinder 302, the pulley 315 can convert the sliding friction between the inclined waist side of the locking block 306 and the connecting block 303 into rolling friction, thereby making the process of the connecting block 303 being inserted into the connecting cylinder 301 smoother. The locking mechanism 3 also includes an annular hole 310 and an adjusting ring 312. The annular hole 310 is opened on the outer wall of the mounting cylinder 302. Several sliders 311 are slidably connected to the inner wall of the annular hole 310. The sliders 311 are fixedly connected to the inner wall of the adjusting ring 312. Two arc-shaped holes 313 are opened on the surface of the adjusting ring 312. A limit rod 309 is slidably connected to the inner wall of the arc-shaped hole 313. The lower end of the limit rod 309 is fixedly connected to the arc surface of the slide rod 307. When it is necessary to control the two sliding rods 307 to move simultaneously away from each other, the operator first rotates the adjusting ring 312. As the adjusting ring 312 rotates, the slider 311 fixed on it slides along the inner wall of the annular hole 310, thus providing support for the rotation of the adjusting ring 312. Simultaneously, the rotation of the adjusting ring 312 drives two limiting rods 309 via two arc-shaped holes 313. The limiting rods 309 then drive the sliding rods 307, enabling the two sliding rods 307 to move simultaneously away from each other. This structure achieves the effect of simultaneously controlling the movement of the two sliding rods 307. A handle 314 is fixedly connected to the upper surface of the adjusting ring 312. The arc surface of the handle 314 is evenly provided with several anti-slip textures. The operator can grip the handle 314 to rotate the adjusting ring 312, achieving convenient control of its rotation.

[0034] In the embodiments of this utility model, please refer to Figure 5The sealing mechanism 4 includes a lead screw 43, which is rotatably connected to the upper surface of the top plate 6. An ear plate 42 is threaded onto the arc surface of the lead screw 43. A sealing cover 41 is fixedly connected to one side of the ear plate 42, and the inner wall of the sealing cover 41 is in contact with the top plate 6. By setting the sealing mechanism 4, when the injection mold is not in use, the sealing cover 41 can be adjusted to seal the upper mold 9 and the lower mold 2, thereby preventing dust and other dirt from adhering to the lower mold 2 and the upper mold 9 and affecting the quality of the injection molded product. A driven gear 44 is fixedly connected to the arc surface of the lead screw 43. A motor base 45 is fixedly connected to the upper surface of the top plate 6. A servo motor 46 is fixedly connected to the inner wall of the motor base 45. A driving gear 47 is fixedly connected to the output end of the servo motor 46, and the driving gear 47 meshes with the driven gear 44. When it is necessary to control the rotation of the lead screw 43, the servo motor 46 is started to drive the drive gear 47 to rotate. The drive gear 47 drives the driven gear 44 to rotate, and the driven gear 44 drives the lead screw 43 to rotate. By setting the above structure, the effect of automatically controlling the rotation of the lead screw 43 is achieved. A sealing ring 48 is fixedly connected to the lower surface of the sealing cover 41. The size of the sealing ring 48 is adapted to the lower surface of the sealing cover 41. When the sealing cover 41 covers the mold, the sealing ring 48 can block the tiny gap between the sealing cover 41 and the base 1, thereby improving the sealing performance at the connection between the sealing cover 41 and the base 1.

[0035] The working principle of the injection mold stabilizing and locking device provided by this utility model is as follows: When the injection mold needs to be used, the cylinder 7 is first started to drive the mounting plate 8, so that the mounting plate 8 moves along the arc surface of the column 5. The mounting plate 8 drives the upper mold 9, so that the upper mold 9 abuts against the lower mold 2. After the upper mold 9 abuts against the lower mold 2, the operation of the cylinder 7 can be stopped. Then, the injection molding machine injects the raw material into the mold cavity formed by the upper mold 9 and the lower mold 2 through the injection hole 10. After injection molding, the cylinder 7 is started to drive the upper mold 9 to separate from the lower mold 2. Finally, the demolding operation is performed. The upper mold 9 can be locked by setting a locking component. Specifically... The steps are as follows: During the movement of the upper mold 9 to the lower mold 2, the mounting plate 8 will drive the connecting rod 304, which in turn drives the connecting block 303 to insert into the mounting cylinder 302. After the connecting block 303 enters the mounting cylinder 301, it will press against the inclined sides of the two locking blocks 306 inside the mounting cylinder 302, thereby squeezing the locking blocks 306 into the rectangular hole 305. At the same time as the upper mold 9 and the lower mold 2 abut against each other, the connecting block 303 will be inserted into the mounting cylinder 301. At this time, the spring 308 will drive the locking blocks 306, causing the two locking blocks 306 to move in opposite directions towards each other simultaneously. When the locking blocks 306... After the lower surface of 06 is attached to the upper surface of the connecting block 303, the locking operation of the connecting block 303 can be completed, thereby locking the mounting plate 8 and the upper mold 9. When the upper mold 9 needs to be unlocked after the injection molding operation is completed, the operator first holds the handle 314 and rotates the adjusting ring 312. When the adjusting ring 312 rotates, the slider 311 fixed on the adjusting ring 312 will slide along the inner wall of the annular hole 310, thereby providing support for the rotation of the adjusting ring 312. At the same time, the adjusting ring 312 will drive the two limit rods 309 through the two arc holes 313. The limit rods 309 drive... The slide bar 307 allows two slide bars 307 to move simultaneously in a direction away from each other. The slide bar 307 drives the locking block 306 into the rectangular hole 305. When the locking block 306 separates from the connecting block 303, the locking of the connecting block 303, the mounting plate 8 and the upper mold 9 can be released. At this time, the cylinder 7 can drive the upper mold 9 back to its original position. When the connecting block 303 is inserted into the inner wall of the mounting cylinder 302, the pulley 315 can change the sliding friction between the inclined side of the locking block 306 and the connecting block 303 into rolling friction, so that the process of the connecting block 303 being inserted into the connecting cylinder 301 is smoother.

[0036] When the injection mold is not in use and needs to be covered and sealed, first start the servo motor 46 to drive the drive gear 47 to rotate. The drive gear 47 drives the driven gear 44 to rotate, and the driven gear 44 drives the lead screw 43 to rotate. When the lead screw 43 rotates, it drives the ear plate 42, causing the ear plate 42 to move downward along the arc surface of the lead screw 43. The ear plate 42 drives the sealing cover 41 to move downward. When the sealing cover 41 and the sealing ring 48 are in contact with the upper surface of the base 1, the operation of the servo motor 46 can be stopped. At this time, the sealing cover 41 will cover the upper mold 9 and the lower mold 2 in the mold, thereby preventing external dust and other dirt from entering. Attached to the interior of the upper mold 9 and the lower mold 2, when the sealing cover 41 needs to be opened, the servo motor 46 is started to drive the drive gear 47 to rotate in the opposite direction. The drive gear 47 drives the driven gear 44 to rotate in the opposite direction. The driven gear 44 drives the lead screw 43 to rotate in the opposite direction. The lead screw 43 drives the ear plate 42, causing the ear plate 42 to move the sealing cover 41 upward. When the sealing cover 41 is fully opened, the operation of the servo motor 46 can be stopped. When the sealing cover 41 covers the mold, the sealing ring 48 can block the tiny gap between the sealing cover 41 and the base 1, thereby improving the sealing performance at the connection between the sealing cover 41 and the base 1.
