Description

Technical Field

[0001] This application relates to the field of mold technology, and in particular to a mold for processing fire extinguisher heads. Background Technology

[0002] A fire extinguisher is a portable fire-fighting tool. With increasing awareness of fire prevention, the demand for fire extinguishers is growing. The fire extinguisher cylinder consists of three parts: the upper end cap, the cylinder body, and the lower end cap. The end cap of a fire extinguisher is generally manufactured using a stamping process.

[0003] A search revealed that Chinese Patent CN212144222U discloses a mold device suitable for precise positioning. This device, through a structure of a triangular positioning bar, a triangular groove, a second positioning rod, a positioning slot, and a first positioning rod, can effectively position the vertical displacement of the first and second mold plates. However, this device does not consider the impact of dust on the mold closing accuracy. The presence of dust easily accelerates the wear of the triangular positioning bar, the first positioning rod, and the second positioning rod, affecting its accuracy. Therefore, a fire extinguisher head processing mold is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a mold for processing fire extinguisher heads, so as to solve the problems mentioned in the background art.

[0005] The embodiments of this application adopt the following technical solutions:

[0006] A fire extinguisher head processing mold includes an upper mold and a lower mold. A guide rod is fixedly connected to the upper surface of the lower mold. An installation hole is opened on the upper surface of the upper mold, and a sliding sleeve is fixedly connected to the inner wall of the installation hole. The sliding sleeve is slidably connected to the surface of the guide rod. Rubber rings are provided at the top and bottom of the sliding sleeve, and the inner ring surface of the rubber ring is in close contact with the surface of the guide rod.

[0007] Preferably, the rubber ring includes a first semicircular body and a second semicircular body, and the ends of the first semicircular body and the second semicircular body are connected to form a rubber ring.

[0010] Preferably, the top and bottom of the sliding sleeve surface are provided with threads, and the guide rod surface is coaxially fitted with a positioning sleeve. The positioning sleeve is fixedly connected to the sliding sleeve by threads. The positioning sleeve applies radial compression force to the rubber ring, causing the rubber ring to produce elastic deformation toward the axis of the guide rod, thereby increasing the contact pressure between the inner ring surface of the rubber ring and the outer surface of the guide rod.

[0011] Preferably, a limit block is fixedly connected to the top of the guide rod.

[0012] Preferably, the upper module includes a top plate, and an upper module is fixedly connected to the lower surface of the top plate; the lower module includes a bottom plate, and a lower module is fixedly connected to the upper surface of the bottom plate; the upper surface of the lower module is provided with a cavity.

[0013] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects:

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-5 This utility model provides a fire extinguisher head processing mold for processing and forming the head during fire extinguisher production. It reduces guide rod wear and ensures mold closing accuracy. Technical solution:

[0025] A fire extinguisher head processing mold includes an upper module 1 and a lower module 2. A guide rod 3 is fixedly connected to the upper surface of the lower module 2. An installation hole is opened on the upper surface of the upper module 1, and a sliding sleeve 4 is fixedly connected to the inner wall of the installation hole. The sliding sleeve 4 is slidably connected to the surface of the guide rod 3. Rubber rings 5 ​​are provided at the top and bottom of the sliding sleeve 4, and the inner ring surface of the rubber ring 5 is in close contact with the surface of the guide rod 3.

[0026] Specifically, by setting a rubber ring 5 that is in close contact with the surface of the guide rod 3, the dust attached to the surface of the guide rod 3 can be removed when the sliding sleeve 4 moves, avoiding the increased wear of the guide rod 3 due to the presence of dust. At the same time, the presence of the rubber ring 5 can prevent dust from entering the interior of the sliding sleeve 4 when the sliding sleeve 4 is stationary, reducing the wear of the guide rod 3, improving its service life, and ensuring the accuracy of mold closing. The upper mold assembly 1 is driven up and down by an external drive.

[0027] The rubber ring 5 includes a first semicircular body 51 and a second semicircular body 52. ​​The ends of the first semicircular body 51 and the second semicircular body 52 are connected to form the rubber ring 5. By setting the first semicircular body 51 and the second semicircular body 52, it is convenient to disassemble and replace the rubber ring 5 when it is severely worn.

[0028] The first semicircular body 51 has a slot 53 at its end, and the second semicircular body 52 has a connector 54 at its end. The slot 53 and the connector 54 are compatible. By setting the connector 54 and the slot 53, it is easy to connect the first semicircular body 51 and the second semicircular body 52.

[0029] The snap connector 54 includes a strip-shaped rod 541 extending outward from the end of the second semicircular body 52. ​​The end of the rod 541 is formed with a semicircular end 542. By providing the end 542, the stability of the connection between the first semicircular body 51 and the second semicircular body 52 is improved.

[0030] The top and bottom of the sliding sleeve 4 are provided with threads 41. The guide rod 3 is coaxially fitted with a positioning sleeve 6. The positioning sleeve 6 is fixedly connected to the sliding sleeve 4 through the threads 41. The positioning sleeve 6 applies radial compression force to the rubber ring 5, causing the rubber ring 5 to undergo elastic deformation toward the axis of the guide rod 3, increasing the contact pressure between the inner ring surface of the rubber ring 5 and the outer surface of the guide rod 3. The inner wall of the positioning sleeve 6 is provided with an internal thread 41 that mates with the threads 41. The positioning sleeve 6 is used to position the rubber ring 5, fixing it at the top and bottom of the sliding sleeve 4. At the same time, the positioning sleeve 6 applies pressure to the rubber ring 5, causing the rubber ring 5 to deform toward the axis of the guide rod 3, increasing the contact pressure between the inner ring surface of the rubber ring 5 and the guide rod 3, and improving the dust removal and dust prevention effect of the rubber ring 5.

[0031] A limit block 7 is fixedly connected to the top of the guide rod 3. The upper module 1 is limited by the limit block 7 to prevent it from detaching from the guide rod 3.

[0032] The upper module 1 includes a top plate 11, and an upper module 12 is fixedly connected to the lower surface of the top plate 11. The lower module 2 includes a bottom plate 21, and a lower module 22 is fixedly connected to the upper surface of the bottom plate 21. A cavity 23 is provided on the upper surface of the lower module 22.

[0033] Working principle: When the fire extinguisher head processing mold is used, the user first places the material on the top of the lower module 22, corresponding to the upper module 12. When the upper module 12 and the lower module 22 are closed, the material is stamped and formed. During this process, the sliding sleeve 4 will move along the surface of the guide rod 3. The rubber ring 5 can remove the dust attached to the surface of the guide rod 3 when the sliding sleeve 4 moves, avoiding the aggravation of the wear of the guide rod 3 due to the presence of dust. At the same time, the presence of the rubber ring 5 can prevent dust from entering the interior of the sliding sleeve 4 when the sliding sleeve 4 is stationary, reducing the wear of the guide rod 3, improving its service life, and ensuring the accuracy of mold closing.
