[0002] Molds are essential industrial production tools that form raw materials into specific shapes and sizes by applying pressure, injecting materials, or other molding methods. For example, in an injection mold, plastic pellets are heated and melted before being injected into the mold cavity. After cooling and solidification, the plastic product is formed into the shape of the mold cavity.

[0003] Many steps in mold production require the assistance of fixtures to ensure stable mold positioning and improve processing accuracy. Currently, most fixtures used in mold production use screws as the driving parts for clamping. However, the impulse speed of the screw is slow, which often takes a long time to adjust large strokes. For example, after clamping a smaller product, a longer upper stroke is required to clamp a larger product. The slow clamping speed easily affects processing efficiency. Therefore, those skilled in the art provide a quick clamping tooling structure for mold production to solve the problems raised in the above background technology. Utility Model Content

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Please see the attached Figures 1 to 5 As shown, a quick clamping tooling structure for mold production in an embodiment of the present invention includes a base 1, a fixed seat 2 is fixed on one side of the upper end surface of the base 1, and a movable seat 4 is slidably connected to the other side of the upper end surface of the base 1. A clamping component 5 is provided on the upper side of the movable seat 4, and the clamping component 5 can be independently adjusted for clamping. A locking component 6 is provided on the lower side of the movable seat 4. The movable seat 4 adopts a sliding connection method. When clamping the mold, the movable seat 4 can quickly adjust the distance from the fixed seat 2 by sliding. After adjusting to the appropriate distance, the clamping component 5 is used for clamping, which directly reduces the distance that needs to be slowly adjusted during the stroke, so that the clamping speed is faster during the adjustment of long strokes, which can effectively improve the processing efficiency. Among them, the locking component 6 is used to lock the movable seat 4 during clamping, thereby ensuring a stable clamping effect.

[0028] Specifically, the locking assembly 6 includes a through slot 61 formed on the lower side of the movable seat 4. Slide rods 66 are fixed to both sides of the through slot 61. A connecting plate 65 is slidably sleeved between the two slide rods 66. A positioning plate 63 extending from the movable seat 4 is fixedly connected to the middle of the lower end surface of the connecting plate 65. A plurality of locking posts 64 are fixed to the lower end surface of the positioning plate 63.

[0029] A groove 7 is provided in the middle of the upper end surface of the base 1, and a plurality of positioning strips 8 are fixed inside the groove 7. A plurality of positioning holes 11 are spaced apart on the upper end surface of the positioning strip 8. The lower end of the positioning plate 63 extends into the interior of the groove 7, and the locking column 64 is plugged into the positioning holes 11 one by one; through the above arrangement, pulling up the connecting plate 65 can drive the locking column 64 to move upward, separate from the positioning hole 11, and complete the unlocking. When clamping the mold, the movable seat 4 can first be moved to the edge of the mold by sliding, and then the locking column 64 is aligned with the positioning hole 11 closest to this position, and the locking column 64 is plugged into the positioning hole 11, thereby completing the locking positioning of the movable seat 4.

[0030] It should be noted that multiple positioning strips 8 are arranged parallel to the direction of the groove 7, and an oblique angle is set at the opening edge of the positioning hole 11. The arrangement of multiple positioning strips 8 can disperse the force and prevent the positioning strips 8 from deforming, and the oblique angle set on the positioning hole 11 facilitates the insertion of the locking column 64.

[0031] In addition, for ease of use, both ends of the connecting plate 65 extend out of the through slot 61 and are fixedly connected to a handle 62. The outer end of the slide rod 66 is sleeved with a spring 67. The upper and lower ends of the spring 67 respectively abut against the top of the through slot 61 and the connecting plate 65. Through the setting of the handle 62, it is convenient for people to pull up and press down the connecting plate 65 to unlock and lock. The movable seat 4 can also be directly pushed and pulled through the handles 62 on both sides. When operated by personnel, the actions of unlocking, locking, and pushing and pulling the movable seat 4 can all be completed by operating one component, which is convenient and quick to use and conforms to conventional usage habits. The set spring 67 can maintain the locked state through elastic force. When vibration occurs, the locking column 64 is not easy to disengage from the positioning hole 11.

[0032] In order to further prevent the connecting plate 65 from deflecting and ensure the stability of the connecting plate 65 during operation, guide grooves 68 are provided on both sides of the through groove 61, and guide columns 69 are fixedly connected on both sides of the connecting plate 65. The guide columns 69 and the guide grooves 68 are slidably connected in a one-to-one correspondence. The connecting plate 65 is further limited by the guide columns 69 and the guide grooves 68 to ensure its stable state during operation.

[0033] See also Figure 1As shown, as an embodiment of the present invention, the clamping assembly 5 includes an adjusting splint 52, which is arranged at the end face of the movable seat 4 close to the fixed seat 2, and a screw 51 is rotatably connected to the middle part of the adjusting splint 52, which is sleeved on the movable seat 4 and fixedly connected to the turning handle 54, and guide rods 53 are fixedly connected on both sides of the adjusting splint 52, which are slidably sleeved on the movable seat 4. When the clamping assembly 5 is in use, the screw 51 is rotated to change the position of the adjusting splint 52, and it is tightened against the mold to complete the clamping and fixing, wherein the guide rod 53 is provided to ensure that the angle of the adjusting splint 52 will not be deflected, so that the clamping is sufficient.

[0034] See also Figure 1 and Figure 2 As shown, as an embodiment of the present invention, slide rails 9 are fixedly connected to both sides of the base 1, and sliders 10 are fixedly connected to both sides of the lower end of the movable seat 4. The sliders 10 are slidably connected to the slide rails 9, and the movable seat 4 is slidably connected to the slide rails 9 fixed on both sides of the base 1 through the sliders 10. While the slide rails 9 play a supporting and guiding role, it also ensures that the movable seat 4 can move smoothly. Among them, arranging the slide rails 9 on both sides of the base 1 can maintain the area of ​​the surface of the base 1 that can be used for clamping, thereby improving the scope of application.

[0035] Please refer again Figure 1 As shown, as an embodiment of the present invention, a fixed splint 3 is provided on the end face of the fixed seat 2 close to the movable seat 4, and the fixed splint 3 is fixedly connected to the fixed seat 2 by bolts. The fixed splint 3 fixed by bolts is detachable and can be replaced after wear, thereby extending the service life of the tooling and reducing the replacement cost. The connecting hole of the bolt adopts a countersunk hole. After the bolt is installed, its end will be hidden in the countersunk hole and will not contact the mold when clamping, thereby preventing damage to the mold or the bolt.

[0036] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
