[0002] Molds are key process equipment used in industrial production to manufacture products with specific shapes, sizes and surface qualities. They are widely used in many fields such as machinery, electronics, automobiles, home appliances, medical devices, and daily necessities. By injecting, pressing or extruding molten materials (such as metals, plastics, etc.) or plastic materials (such as rubber, ceramics, etc.) into the mold cavity, the desired product can be obtained after cooling, solidification or molding.

[0003] A cover is a component in a product or equipment used to cover, protect, or enclose internal parts. It is widely used in machinery, electronics, home appliances, automobiles, medical devices, and other fields. The manufacture of a cover requires the use of molds. During the manufacturing process of the cover, the upper and lower molds may become misaligned or offset during multiple mold closing collisions. This makes the positioning of the upper and lower molds inaccurate and the fastening unstable. It can easily cause the molded cover to be too thick or too thin in some areas, affecting strength and weight control. In some cases, the screw hole positions may be inaccurate, leading to difficulties in subsequent assembly.

[0004] Therefore, there is an urgent need to improve the processing mold used for manufacturing the top cover in order to solve the above-mentioned problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-6 As shown in the figure, this embodiment provides a processing mold for manufacturing a top cover.

[0018] A processing mold for manufacturing a top cover includes a lower mold 1 and an upper mold 2. The lower mold 1 is provided with a positioning calibration mechanism 3. The positioning calibration mechanism 3 includes a first fixing frame 4 symmetrically fixedly installed on both sides of the lower mold 1. A first hydraulic rod 5 is fixedly installed on both sides of the first fixing frame 4. Two positioning frames 6 symmetrically arranged inside the first fixing frame 4 and fixedly connected to the first hydraulic rod 5 are provided. A fixing plate 7 is fixedly installed on both sides of the upper mold 2. A positioning rod 8 is fixedly installed at the bottom of the fixing plate 7. The positioning calibration mechanism 3 enables the positioning calibration of the lower mold 1 and upper mold 2 after multiple mold closing operations. After the upper mold 2 is fastened onto the lower mold 1, the positioning rods 8 on both sides of the upper mold 2 are inserted into the first fixed frame 4. Then, multiple first hydraulic rods 5 are simultaneously activated to drive the two positioning frames 6 to move closer to each other, so that the two positioning frames 6 cover and clamp the positioning rods 8. After the two positioning rods 8 are clamped and positioned by the positioning frames 6, the lower mold 1 and upper mold 2 after mold closing can be calibrated, so that the lower mold 1 and upper mold 2 do not misalign or shift after mold closing, and the stability of the lower mold 1 and upper mold 2 fastening is improved. This effectively avoids the situation of the upper cover molded product being too thick or too thin in some places, while improving the strength of the upper cover molded product and avoiding assembly difficulties caused by inaccurate screw hole positions.

[0019] In this embodiment, as Figures 1-6 As shown, the shape of the inner wall of the positioning frame 6 is adapted to the shape of the outer wall of the positioning rod 8, and the inner diameter of the positioning frame 6 is equal to the outer diameter of the positioning rod 8. Multiple first support frames 9 are fixedly installed on the surface of the lower mold 1. A fixing block 10 is provided on the first support frame 9. A second fixing frame 11 is fixedly installed on the top of the fixing block 10. A pressure plate 12 is movably installed inside the second fixing frame 11. Multiple springs 13 are fixedly installed between the pressure plate 12 and the second fixing frame 11. Multiple pressure blocks 14 are fixedly installed on the surface of the upper mold 2. Multiple bolts 15 are installed at the bottom of the first support frame 9. Multiple threaded grooves 16 are opened at the bottom of the fixing block 10. By matching the inner wall shape of the positioning frame 6 with the outer wall shape of the positioning rod 8, and setting the inner diameter of the positioning frame 6 to be equal to the outer diameter of the positioning rod 8, the two positioning frames 6 fit more tightly against the positioning rod 8 for clamping, thus improving positioning accuracy. The arrangement of the first support frame 9, fixing block 10, second fixing frame 11, pressure plate 12, spring 13, and pressure block 14 provides a buffering effect during the engagement of the lower mold 1 and the upper mold 2. When the upper mold 2 falls, the pressure blocks 14 on both sides contact the pressure plate 12 in the second fixing frame 11, and... As the upper mold 2 continues to descend, the multiple springs 13 at the bottom of the pressure plate 12 can reduce the impact force of the upper mold 2 falling, thereby reducing the collision between the lower mold 1 and the upper mold 2 and preventing damage to the lower mold 1 and the upper mold 2. Through the setting of bolts 15 and threaded grooves 16, the fixing block 10 is installed on the first support frame 9 by connecting multiple bolts 15 and threaded grooves 16, so that the fixing block 10 can be removed from the first support frame 9. This allows the multiple springs 13 at the bottom of the pressure plate 12 to be removed and replaced when they break, thereby avoiding affecting the use.

[0020] In this embodiment, as Figures 1-6As shown, multiple second support frames 17 are symmetrically fixedly installed on the bottom of the lower mold 1. A second hydraulic rod 18 is fixedly installed inside the second support frame 17. A moving wheel 19 is fixedly installed at the output end of the second hydraulic rod 18. A rubber pad 20 is fixedly installed at the bottom of the second support frame 17. A slot is opened in the center of the rubber pad 20. An installation frame 21 is fixedly installed on the lower mold 1. An operation panel 22 is fixedly installed inside the installation frame 21. With the second support frame 17, the second hydraulic rod 18, and the moving wheels 19, multiple second hydraulic rods 18 are activated simultaneously to drive the moving wheels 19 to extend from the bottom of the second support frame 17 to contact the ground and support the lower mold 1 as a whole. Then, the lower mold 1 can be moved in position easily. After the movement is completed, the multiple moving wheels 19 can be retracted to allow the lower mold 1 to fall and be placed stably. With the rubber pad 20, the lower mold 1 can play a shock absorption role when it falls and contacts the ground, reducing damage to the bottom of the lower mold 1. With the installation frame 21 and the operation panel 22, the operation panel 22 is electrically connected to the first hydraulic rod 5 and the second hydraulic rod 18, so that the operation panel 22 can centrally operate the first hydraulic rod 5 and the second hydraulic rod 18, which is convenient for the staff to use.

[0021] In this embodiment, as Figures 1-6 As shown in the figure, the working process of a processing mold for manufacturing a top cover provided in this embodiment is as follows: After the upper mold 2 is fastened onto the lower mold 1, the positioning rods 8 on both sides of the upper mold 2 are inserted into the first fixed frame 4. Then, multiple first hydraulic rods 5 are activated simultaneously to drive the two positioning frames 6 to move closer to each other, so that the two positioning frames 6 cover and clamp the positioning rods 8. After the two positioning rods 8 clamp and position the positioning frames 6, the lower mold 1 and the upper mold 2 after mold closing can be calibrated, so that the lower mold 1 and the upper mold 2 do not misalign or shift after mold closing, and the stability of the fastening of the lower mold 1 and the upper mold 2 is improved. This effectively avoids the situation of the upper cover being too thick or too thin in some places, improves the strength of the upper cover, and avoids the situation of assembly difficulties caused by inaccurate screw hole positions.
