Description

Technical Field

[0001] The utility model relates to the technical field of valve processing molds, in particular to a valve processing mold. Background Art

[0002] Valves are control components in fluid delivery systems, with functions such as cutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief, and are widely used in modern production and life. With the development of society and the advancement of science and technology, the frequency of use of valves has gradually increased, and the requirements for valve precision have become higher and higher. Therefore, the technical development of valve processing molds is crucial to improving the quality and production efficiency of valve products.

[0003] The utility model patent application document with the publication number of "CN214082672U" discloses a processing mold for precision valves, which relates to the technical field of valve processing molds, and is designed to solve the problem that the existing processing molds for precision valves have low cooling efficiency and cannot adapt to continuous production and processing. A lower mold base is installed on the upper surface of the processing table, and a lower cooling coil is installed on the outer wall of the lower mold base. A support top plate is arranged above the processing table, and the support top plate is fixedly connected to the processing table through a support rod. An upper mold base is installed on the lower surface of the support top plate, and an upper cooling coil is arranged on the outer wall of the upper mold base. The upper mold base and the lower mold base are both provided with mold cavities inside, and a main flow channel is provided at the upper end of the upper mold base, which extends to the outside of the support top plate and is connected to the mold cavity in the upper mold base. A condenser is installed on one side of the processing table, and a support leg is installed below the processing table, and four support legs are arranged, and a bearing plate is installed between the four support legs.

[0004] The processing mold for precision valves disclosed in the above document has the following defects: during injection molding, this technical solution can only mold valves of one size, and cannot mold valves of multiple models, and its flexibility of use is relatively low.

[0005] It can be seen from this that the existing precision valve processing mold does not have a structure that is convenient for replacing different molds. It is necessary to improve the existing deficiencies and provide a valve processing mold. Utility Model Content

[0006] The purpose of the utility model is to provide a valve processing mold to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model relates to a valve processing die, which comprises a machine base. Four groups of support rods are fixedly installed on the upper surface of the machine base. One end of each support rod is fixedly installed with a top plate. Mounting seats are installed on the outer surfaces of both the machine base and the top plate. An upper die is installed inside one group of mounting seats, and a lower die is installed inside the other group of mounting seats. A driving component is installed on the lower surface of the machine base. Two groups of positioning holes are formed on both sides of the upper die and the lower die. A feeding pipe is fixedly installed on the inner wall of the top plate. A through groove is formed in the inner wall of the upper die, and the through groove is communicated with the feeding pipe. Clamping components are installed on both sides of the two groups of mounting seats.

[0009] Further, the clamping component comprises a fixed sleeve. Two groups of sliding plates are slidably connected to the inner wall of the fixed sleeve. One side of each of the two sliding plates is fixedly installed with a connecting rod. The connecting rod is slidably connected to the inner wall of the fixed sleeve and extends to the outer surface of the fixed sleeve.

[0010] Further, one end of each connecting rod is fixedly installed with a connecting plate. One end of the connecting plate is fixedly installed with a plugging rod, and the plugging rod is clamped with the positioning hole.

[0011] Further, extension plates are fixedly installed on the outer surfaces of the sliding plates. The extension plates are slidably connected to the inner wall of the fixed sleeve. Two groups of vertical plates are fixedly installed on the outer surface of the fixed sleeve.

[0012] Further, a bidirectional screw rod is slidably connected to the inner walls of the two groups of vertical plates. The left - hand and right - hand threads of the bidirectional screw rod are respectively slidably connected to the two groups of extension plates. One end of the bidirectional screw rod is fixedly installed with a handle part.

[0013] Further, the driving component comprises a frame and a cylinder. The frame is fixedly installed on the lower surface of the machine base. The cylinder is fixedly installed on the inner wall of the frame. The output end of the cylinder is connected to one group of mounting seats.

[0014] Further, a guiding slide bar is slidably connected to the inner wall of the machine base. The guiding slide bar is connected to the mounting seat.

[0015] The utility model has the following beneficial effects:

[0016] (1) By rotating the handle part of the utility model, the bidirectional screw rod is driven to rotate. Due to the design of the left - hand and right - hand threads of the bidirectional screw rod, two groups of sliding plates can be simultaneously pushed to slide towards or away from each other. The plugging rod is driven to move through the connecting rod and the connecting plate, so that the plugging rod is clamped with or disengaged from the positioning holes on the upper die and the lower die, and thus the replacement of the upper die and the lower die can be completed. The replacement is convenient and fast, which enables the processing of valves of different models and improves the use flexibility.

[0017] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Please refer to Figure 1 - Figure 4As shown in the figure, the utility model is a valve processing die, which includes a machine base 1. Four groups of support rods 2 are fixedly installed on the upper surface of the machine base 1. One end of each support rod 2 is fixedly installed with a top plate 3. Mounting seats 4 are installed on the outer surfaces of both the machine base 1 and the top plate 3. An upper die 6 is installed inside one group of mounting seats 4, and a lower die 7 is installed inside the other group of mounting seats 4. A driving component is installed on the lower surface of the machine base 1. Two groups of positioning holes 11 are formed on both sides of the upper die 6 and the lower die 7. A feeding pipe 12 is fixedly installed on the inner wall of the top plate 3. A through groove 601 is formed on the inner wall of the upper die 6, and the through groove 601 is communicated with the feeding pipe 12. Clamping components 5 are installed on both sides of the two groups of mounting seats 4;

[0027] The clamping component 5 includes a fixed sleeve 501. Two groups of sliding plates 502 are slidably connected to the inner wall of the fixed sleeve 501. One side of each of the two sliding plates 502 is fixedly installed with a connecting rod 503. The connecting rod 503 is slidably connected to the inner wall of the fixed sleeve 501 and extends to the outer surface of the fixed sleeve 501;

[0028] One end of each connecting rod 503 is fixedly installed with a connecting plate 504. One end of the connecting plate 504 is fixedly installed with a plugging rod 505, and the plugging rod 505 is clamped with the positioning hole 11;

[0029] Extension plates 506 are fixedly installed on the outer surfaces of the sliding plates 502. The extension plates 506 are slidably connected to the inner wall of the fixed sleeve 501. Two groups of vertical plates 507 are fixedly installed on the outer surface of the fixed sleeve 501;

[0030] Two groups of vertical plates 507 are slidably connected with a bidirectional screw rod 508 on their inner walls. The left - hand and right - hand threads of the bidirectional screw rod 508 are respectively slidably connected with the two groups of extension plates 506. One end of the bidirectional screw rod 508 is fixedly installed with a grip part 509;

[0031] By rotating the grip part 509, the bidirectional screw rod 508 is driven to rotate. Due to the design of the left - hand and right - hand threads of the bidirectional screw rod 508, the two groups of sliding plates 502 can be simultaneously pushed to slide towards or away from each other. The plugging rod 505 is driven to move through the connecting rod 503 and the connecting plate 504, realizing the clamping or separation of the plugging rod 505 from the positioning holes 11 on the upper die 6 and the lower die 7, thus completing the replacement of the upper die 6 and the lower die 7.

[0033] A guiding slide bar 10 is slidably connected to the inner wall of the machine base 1, and the guiding slide bar 10 is connected to the mounting seat 4.

[0034] In use, first, the starting cylinder 9 drives the mounting seat 4 for mounting the lower mold 7 to move upward. At the same time, the guiding slide rod 10 slides on the inner wall of the machine base 1 to ensure the stability of the movement. When the lower mold 7 is closed with the upper mold 6, the feeding pipe 12 injects the material into the mold through the through groove 601 to form a preliminary shape of the valve. After the molding is completed, by operating the above structure in reverse, demolding can be completed. When processing valves of different models, by rotating the grip part 509, the bidirectional screw 508 is driven to rotate. Due to the left and right hand thread design of the bidirectional screw 508, two groups of sliding plates 502 can be simultaneously pushed to slide towards or away from each other. The insertion rod 505 is driven to move through the connecting rod 503 and the connecting plate 504, so that the insertion rod 505 is clamped or disengaged from the positioning holes 11 on the upper mold 6 and the lower mold 7, and thus the replacement of the upper mold 6 and the lower mold 7 can be completed. The replacement is convenient and fast, enabling the processing of valves of different models and improving the flexibility of use.
