Description

Technical Field

[0001] The utility model relates to the technical field of mold processing jigs, in particular to a molding die jig. Background Art

[0002] Compression molds are various molds and tools used in industrial production to produce desired products through methods such as injection molding, blow molding, die casting, forging, smelting, and stamping. Compression mold jigs, on the other hand, are auxiliary tools used to secure molds and components during the mold processing and manufacturing process, facilitating various processing, assembly, and testing tasks. Their function is to help precisely secure the mold and reduce mold errors and deformation during polishing, thereby improving processing quality and increasing production efficiency.

[0003] In the actual polishing process of molds, most of the existing mold pressing tools can only perform relative positioning of the mold. However, the mold needs to be processed and polished on more than one surface. Therefore, when the side of the mold needs to be polished, the mold needs to be removed and re-clamped and positioned. In some cases, other jigs may also need to be replaced. In addition, the mold is usually heavy. These combined factors make the operation cumbersome, time-consuming and labor-intensive, which not only reduces production efficiency but also increases labor costs. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0019] Next, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, cross-sectional views of device structures may be partially enlarged and not to scale when describing the embodiments of the present invention. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0021] Figure 1-Figure 3 Shown is a schematic diagram of the entire structure of a mold tool of the utility model, please refer to Figure 1-Figure 3, a molding die processing tool of the present embodiment includes a base 100, a disc-shaped processing table 200 is horizontally rotatably installed in the center of the upper part of the base 100, and a rotation drive device 300 is provided inside the base 100 for driving the processing table 200 to rotate horizontally, and opposite side clamps 400 and a first cylinder 410 for driving the side clamps 400 on both sides to move relative to or opposite to each other are provided on the upper end of the base 100 and located on both sides of the processing table 200, a movable frame 500 is horizontally slidably installed along the length direction of the rear part of the base 100, and a reciprocating drive device 600 for driving the movable frame 500 to move left and right, a pressure plate 510 is provided on the inner top of the upper end of the movable frame 500 and is located above the processing table 200, and a second cylinder 520 for driving the pressure plate 510 to move up and down.

[0022] The rotary drive device 300 includes a spindle 310 vertically fixed at the center of the bottom circle of the processing table 200, a bevel gear 1 320 fixed to the outer periphery of the spindle 310, a servo motor 1 330 mounted within the base 100, and a bevel gear 2 340 disposed at the output end of the servo motor 1 330 and meshing with the bevel gear 1 320. During operation, the servo motor 1 330 drives the bevel gear 1 320 to rotate via the bevel gear 2 340, which in turn drives the spindle 310 and the processing table 200 to rotate synchronously, causing the mold to be processed on the processing table 200 to rotate accordingly, thereby achieving the purpose of changing different sides and automatically switching the mold's processing surface to the polishing surface. The reciprocating drive device 600 includes a slide 610 fixed to the lower rear end of the mobile frame 500, a chute 620 provided at the rear of the base 100 and slidably matched with the slide 610, a lead screw 630 rotatably mounted on the inner side of the chute 620 at both ends and threadedly connected to the slide 610 via a ball nut, and a servo motor 2 640 provided on the base 100 with its output end connected to one end of the lead screw 630. When it is necessary to tighten and stabilize the mold on the upper portion of the processing table 200, the lead screw 630 is rotated by the servo motor 2 640, and the slide 610 and the mobile frame 500 are driven to move toward the middle position of the base 100 with the cooperation of the chute 620 and the like, so that the pressing plate 510 is above the mold. Subsequently, the second cylinder 520 pushes the pressing plate 510 downward and tightens and stabilizes the mold to prevent the mold from shifting during the grinding and polishing process. Specifically, in this embodiment, the mold is placed on the processing table 200 and the mold is clamped at a certain temperature by using the cylinders on both sides and the side clamps 400. In this way, the upper part and part of the side of the mold can be polished and ground conveniently. When the angle needs to be switched, the mold processing table 200 is driven to rotate by the rotary drive device 300 and the mold is also clamped firmly by using the side clamps 400. When it is necessary to grind the sides of irregular molds such as arcs, the side clamps 400 on both sides will be separated from the mold. At this time, the upper pressure plate 510 will press the mold firmly under the action of the cylinder, and cooperate with the rotatable processing table 200 to flexibly adjust and position the angle of the mold. In summary, the mold pressing tool effectively improves the positioning efficiency of the mold, greatly reduces the probability of needing to replace the fixture, is simple to operate, saves time and effort, and further optimizes the use cost and processing efficiency.

[0023] It should be noted that the facades of the molded molds on the market are not all regular rectangular structures, but also circular, elliptical or other irregular shapes. Therefore, when it is necessary to grind a certain lateral arc angle, the pressing plate 510 can be used in the vertical direction and cooperate with the rotating processing table 200 to position the mold at any angle, which is flexible and convenient and has good practicality.

[0024] The clamping surfaces of the side clamping plates 400 and the clamping surfaces of the pressure plate 510 are both provided with anti-slip pads 700. A positioning seat for fixing the first cylinder 410 is also provided on the upper portion of the base 100. It is understood that the anti-slip pads 700 prevent the side clamping plates 400 and the pressure plate 510 from excessively squeezing the mold and causing surface damage, while also increasing friction and preventing slipping.

[0025] Furthermore, the base 100 further includes an annular support platform 120, coaxial with the processing table 200 and used to support the bottom of the processing table 200. A bearing ring 130 is located between the top of the annular support platform 120 and the processing table 200. Furthermore, the base 100 also has an escape groove 110 corresponding to the processing table 200 on the upper portion. The cooperation between the annular support platform 120 and the bearing ring 130 makes the processing table 200 more stable during horizontal rotation, ensuring the polishing accuracy of the mold.

[0026] Furthermore, the jig assembly's master control unit, controller H, is located outside the base 100. The bottom of the processing table 200 also has an angle sensor connected to the controller H. As can be appreciated, the mold's rotation and the angle to be polished require strict control. Therefore, the angle sensor accurately detects the rotation angle of the processing table 200 and the mold. Controller H uses this feedback to control the output stroke of servo motor 1 330, ensuring precise processing and stable positioning of the mold.

[0027] In summary, the present embodiment is a mold pressing tool. When polishing, the mold is placed on the processing table 200 and the mold is clamped at a temperature by using the cylinders on both sides and the side clamps 400. In this way, the upper part and part of the side of the mold can be polished and polished conveniently. When the angle needs to be switched, the mold processing table 200 is driven to rotate by the rotary drive device 300 and the mold is also clamped firmly by using the side clamps 400. When the side of an irregular mold such as an arc needs to be polished, the side clamps 400 on both sides will be separated from the mold. At this time, the upper pressure plate 510 will press the mold firmly under the action of the cylinder, and cooperate with the rotatable processing table 200 to flexibly adjust and position the angle of the mold. In summary, the mold pressing tool effectively improves the positioning efficiency of the mold, greatly reduces the probability of needing to replace the fixture, is simple to operate, and saves time and effort.

In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation.
