Description

Technical Field

[0001] This utility model relates to the technical field of mold positioning devices, and in particular to a positioning structure for a cylinder end cap mold insert. Background Technology

[0002] As the core sealing and connecting component of the cylinder, the cylinder end cap needs to be injection molded. In order to meet assembly requirements, metal inserts need to be embedded during the molding process. The positioning accuracy of the inserts directly determines the assembly accuracy and sealing performance of the cylinder end cap. As pneumatic components develop towards "miniaturization and high precision", the traditional insert positioning structure is no longer suitable for production needs.

[0003] In existing technologies, traditional cylinder end cap mold insert positioning devices rely heavily on manual visual alignment or simple snap-fit ​​structures for insert positioning. Manual alignment is susceptible to the influence of operator experience and ambient lighting, while simple snap-fit ​​structures suffer from large clearances, both leading to insert positioning deviations. These deviations directly result in the insert and cylinder barrel exhibiting coaxiality exceeding industry standards during cylinder end cap assembly, severely impacting cylinder sealing performance and assembly quality, and increasing the risk of product scrap. Utility Model Content

The outer wall of the threaded rod is threadedly connected to the inner wall of the mold placement box. A connecting block is rotatably connected to the end of the threaded rod away from the rotating groove. A first limiting rod is fixedly connected to the inner wall of the connecting block, and a second limiting rod is fixedly connected to the inner wall of the clamping connecting block.

An operating handle is fixedly connected to the end of the threaded rod away from the rotating groove.

[0007] As a further improvement to the above solution, the outer wall of the first limiting rod is slidably connected to the inner wall of the mold placement box, the outer wall of the second limiting rod is slidably connected to the inner wall of the mold placement box, two T-shaped connecting grooves are provided, and three rotating grooves are provided.

[0008] As a further improvement to the above solution, the connecting component includes a T-shaped connecting block, a mold clamping block is fixedly connected to the surface of the T-shaped connecting block, the outer wall of the T-shaped connecting block is slidably connected to the inner wall of the T-shaped connecting groove, and the outer wall of the mold clamping block is in contact with the surface of the clamping connecting block.

[0009] With the above technical solution, the operator rotates the operating handle fixed at the end of the threaded rod away from the rotating groove, causing the threaded rod to rotate synchronously; the outer wall of the threaded rod is threadedly connected to the inner wall of the mold placement box, and its end near the rotating groove is rotatably connected to the rotating groove in the inner wall of the clamping connecting block. The rotating threaded rod, with the help of the threaded engagement, converts the rotational motion into the horizontal movement force of the clamping connecting block.

[0010] As a further improvement to the above solution, a positioning hole is provided on the top of the clamping connecting block, a positioning rod is slidably connected to the inner wall of the positioning hole, a fixing block is fixedly connected to the top of the positioning rod, and a limit groove is provided on the top of the clamping connecting block.

[0011] As a further improvement to the above solution, a reset spring is fixedly connected to the bottom of the inner wall of the limiting slide, a reset plate is fixedly connected to the top of the reset spring, a limiting groove is opened at the top of the limiting slide, and the outer wall of the reset plate is slidably connected to the inner wall of the limiting groove.

[0012] As a further improvement to the above solution, a guide groove is provided at the top of the limiting groove, a connecting rod is slidably connected to the inner wall of the guide groove, the outer wall of the connecting rod is slidably connected to the inner wall of the limiting groove, and the bottom of the connecting rod is in contact with the top of the reset plate.

[0013] As a further improvement to the above solution, the top of the connecting rod penetrates through the inner wall of the fixing block and extends therein. A slot is provided on the surface of the fixing block, and a plastic cap is engaged with the inner wall of the slot. The outer wall of the plastic cap contacts the surface of the connecting rod. An unlocking slot is provided on the top of the fixing block.

[0014] The above technical solution aligns the mold clamping block fixed on the surface of the T-shaped connecting block with the clamping connecting block, so that the outer wall of the T-shaped connecting block slides along the inner wall of the T-shaped connecting groove on the surface of the clamping connecting block. During the sliding process, the outer wall of the mold clamping block always fits against the surface of the clamping connecting block. With the help of the anti-detachment characteristics of the T-shaped structure, the initial positioning of the connecting component and the clamping component is quickly completed.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention allows the operator to rotate the threaded rod by turning the handle fixed at the end away from the rotating groove, causing the threaded rod to rotate synchronously. The outer wall of the threaded rod is threadedly connected to the inner wall of the mold placement box, and its end near the rotating groove is rotatably connected to the rotating groove in the inner wall of the clamping connecting block. The rotating threaded rod, through the threaded engagement, converts the rotational motion into a horizontal moving force for the clamping connecting block. Limiting rod one and limiting rod two, fixed to the inner wall of the connecting block, have their outer walls at the ends away from the connecting block fixed to the inner wall of the clamping connecting block, and both outer walls are slidably connected to the inner wall of the mold placement box. When the clamping connecting block moves... When the threaded rod moves, limit rod one and limit rod two slide synchronously along the inner wall of the mold placement box, restricting the rotational freedom of the clamping connecting block and preventing it from shifting or tilting due to the rotation of the threaded rod. The two T-shaped connecting grooves on the surface of the clamping connecting block provide an installation interface for the subsequent clamping block. Thus, by rotating the connecting block, the connecting block rotates the threaded rod, and the threaded rod drives the clamping connecting block to slide under the threaded connection with the mold placement box. This allows it to be used with molds of different sizes, meet the requirements of high-precision assembly, improve the product assembly qualification rate, and reduce scrap losses caused by positioning deviations.

[0017] This invention aligns a mold clamping block fixed to the surface of a T-shaped connecting block with the clamping connecting block, allowing the outer wall of the T-shaped connecting block to slide along the inner wall of the T-shaped connecting groove on the surface of the clamping connecting block. During the sliding process, the outer wall of the mold clamping block remains in contact with the surface of the clamping connecting block. Utilizing the anti-detachment characteristic of the T-shaped structure, the initial positioning of the connecting component and the clamping component is quickly completed. Pressing the fixing block causes the positioning rod fixed at its bottom to slide and insert along the inner wall of the positioning hole at the top of the clamping connecting block. During the insertion of the positioning rod, the fixing block moves downwards synchronously. Then, by pushing the connecting rod downwards, it slides down along the inner wall of the guide groove and the limiting groove, squeezing the reset plate. After being squeezed by the connecting rod, it slides downward along the inner wall of the limiting groove, compressing the return spring fixed at the bottom of the inner wall of the limiting groove. Then, when the bottom of the connecting rod reaches the inner wall of the limiting groove and the top surface contacts the surface of the fixed block, the connecting rod is rotated to make it slide along the surface of the return plate and the inner wall of the limiting groove. Then, the plastic cap is engaged with the inner wall of the slot, and the outer wall of the plastic cap is in contact with the surface of the connecting rod, restricting the rotation of the connecting rod. At the same time, the limiting groove restricts the vertical sliding of the connecting rod, thereby completing the connection between the fixed block and the connecting block through the connecting rod, preventing the T-shaped connecting block from detaching from the T-shaped connecting groove, and completing the limiting and connection of the mold clamping block.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] Example:

A connecting block 205 is rotatably connected to the end of the threaded rod 204 away from the rotating groove 203. A first limiting rod 206 and a second limiting rod 207 are fixedly connected to the inner wall of the connecting block 205. The outer wall of the first limiting rod 206 away from the connecting block 205 is fixedly connected to the inner wall of the clamping connecting block 201. The outer wall of the second limiting rod 207 away from the connecting block 205 is fixedly connected to the inner wall of the clamping connecting block 201. An operating handle 208 is fixedly connected to the end of the threaded rod 204 away from the rotating groove 203.

[0034] Limiting rod 1 206 is slidably connected to the inner wall of mold placement box 1, and limiting rod 2 207 is slidably connected to the inner wall of mold placement box 1. There are two T-shaped connecting grooves 202 and three rotating grooves 203. When clamping connecting block 201 moves with threaded rod 204, limiting rod 1 206 and limiting rod 2 207 slide synchronously along the inner wall of mold placement box 1, limiting the rotational freedom of clamping connecting block 201 and preventing it from shifting or tilting due to the rotation of threaded rod 204. The two T-shaped connecting grooves 202 on the surface of clamping connecting block 201 provide an installation interface for subsequent clamping blocks.

[0035] The connecting component 3 includes a T-shaped connecting block 301, a mold clamping block 302 is fixedly connected to the surface of the T-shaped connecting block 301, the outer wall of the T-shaped connecting block 301 is slidably connected to the inner wall of the T-shaped connecting groove 202, and the outer wall of the mold clamping block 302 is in contact with the surface of the clamping connecting block 201.

[0036] The clamping connecting block 201 has a positioning hole 303 on its top. A positioning rod 304 is slidably connected to the inner wall of the positioning hole 303. A fixing block 305 is fixedly connected to the top of the positioning rod 304. A limit groove 306 is provided on the top of the clamping connecting block 201.

[0037] A reset spring 307 is fixedly connected to the bottom of the inner wall of the limiting slide 306, and a reset plate 308 is fixedly connected to the top of the reset spring 307. A limiting groove 309 is opened at the top of the limiting slide 306, and the outer wall of the reset plate 308 is slidably connected to the inner wall of the limiting groove 309.

[0038] The top of the limiting groove 309 is provided with a guide groove 310, and a connecting rod 311 is slidably connected to the inner wall of the guide groove 310. The outer wall of the connecting rod 311 is slidably connected to the inner wall of the limiting groove 309, and the bottom of the connecting rod 311 is in contact with the top of the reset plate 308.

[0039] The top of the connecting rod 311 penetrates the inner wall of the fixing block 305 and extends thereto. A slot 312 is provided on the surface of the fixing block 305. A plastic cap 313 is engaged with the inner wall of the slot 312. The outer wall of the plastic cap 313 contacts the surface of the connecting rod 311. An unlocking groove 314 is provided on the top of the fixing block 305. By pushing the connecting rod 311 downward, it slides down along the inner wall of the guide groove 310 and the limiting groove 309, squeezing the reset plate 308. After being squeezed by the connecting rod 311, the reset plate 308 slides down along the inner wall of the limiting groove 309, compressing the reset spring 307 fixed at the bottom of the inner wall of the limiting slide groove 306. Then, when the bottom of the connecting rod 311 reaches the inner wall of the limiting groove 309 and the top surface contacts the surface of the fixing block 305, the connecting rod 311 is rotated to make it rotate and slide along the surface of the reset plate 308 and the inner wall of the limiting groove 309.

[0040] The implementation principle of the cylinder end cap mold insert positioning structure in this application embodiment is as follows: the operator rotates the operating handle 208 fixed at the end of the threaded rod 204 away from the rotating groove 203, causing the threaded rod 204 to rotate synchronously; the outer wall of the threaded rod 204 is threadedly connected to the inner wall of the mold placement box 1, and its end near the rotating groove 203 is rotatably connected to the rotating groove 203 in the inner wall of the clamping connecting block 201. The rotating threaded rod 204 converts the rotational motion into the horizontal moving force of the clamping connecting block 201 through the threaded engagement. The limiting rod 1 206 and limiting rod 207 fixed on the inner wall of the connecting block 205 have their outer walls at the ends away from the connecting block 205 fixed to the inner wall of the clamping connecting block 201, and both outer walls are slidably connected to the mold. The mold placement box 1 has an inner wall; when the clamping connecting block 201 moves with the threaded rod 204, the first limiting rod 206 and the second limiting rod 207 slide synchronously along the inner wall of the mold placement box 1, restricting the rotational freedom of the clamping connecting block 201 and preventing it from shifting or tilting due to the rotation of the threaded rod 204. The two T-shaped connecting grooves 202 opened on the surface of the clamping connecting block 201 provide an installation interface for subsequent clamping blocks. Thus, by rotating the connecting block 205, the connecting block 205 rotates the threaded rod 204. The threaded rod 204 drives the clamping connecting block 201 to slide under the threaded connection with the mold placement box 1. This allows it to be used with molds of different sizes, meet the requirements of high-precision assembly, improve the product assembly qualification rate, and reduce scrap losses caused by positioning deviations.Then, the mold clamping block 302 fixed on the surface of the T-shaped connecting block 301 is aligned with the clamping connecting block 201, so that the outer wall of the T-shaped connecting block 301 slides along the inner wall of the T-shaped connecting groove 202 on the surface of the clamping connecting block 201. During the sliding process, the outer wall of the mold clamping block 302 always fits against the surface of the clamping connecting block 201. With the anti-dislodgement characteristics of the T-shaped structure, the initial positioning of the connecting component 3 and the clamping component 2 is quickly completed. Pressing the fixing block 305 causes the positioning rod 304 fixed at its bottom to slide into the inner wall of the positioning hole 303 at the top of the clamping connecting block 201. During the insertion of the positioning rod 304, the fixing block 305 moves downward synchronously. Then, by pushing the connecting rod 311 downward, it slides down along the inner wall of the guide groove 310 and the limiting groove 309, squeezing the reset plate 308. After being squeezed by the connecting rod 311, the reset plate 308 slides down along the inner wall of the limiting groove 309, compressing... A return spring 307 is fixed to the bottom of the inner wall of the limiting groove 306. When the bottom of the connecting rod 311 reaches the inner wall of the limiting groove 309 and the top surface contacts the surface of the fixing block 305, the connecting rod 311 is rotated to slide along the surface of the reset plate 308 and the inner wall of the limiting groove 309. Then, the plastic cap 313 is snapped into the inner wall of the slot 312. The outer wall of the plastic cap 313 is in contact with the surface of the connecting rod 311, restricting the rotation of the connecting rod 311. At the same time, the limiting groove 309 restricts the up and down sliding of the connecting rod 311. Thus, the connection between the fixing block 305 and the connecting block 201 is completed through the connecting rod 311, preventing the T-shaped connecting block 301 from detaching from the T-shaped connecting groove 202. The limiting and connection of the mold clamping block 302 is completed. The plastic cap 313 can be unlocked through the unlocking slot 314 to perform the subsequent disassembly operation of the connecting rod 311.
