Description

Technical Field

[0001] This utility model relates to the field of glove manufacturing technology, and in particular to an auxiliary device for changing metal hand molds. Background Technology

[0002] In the production of PVC gloves, metal hand molds play an indispensable role as a key component. Their main function is to provide molding support for the PVC gloves, ensuring that the gloves achieve precise shape and size during processes such as impregnation and curing. However, due to the complexity of the production environment and the special nature of the processes, metal hand molds need to be replaced periodically.

[0003] The disassembly of widely used metal hand molds presents numerous challenges. Conventional disassembly methods either rely on manual loosening of connecting bolts or the use of specific disassembly tools, both of which require manual operation. However, manual disassembly is not only time-consuming and labor-intensive, but also demands a high level of skill from the operator, making it difficult to disassemble. Improper operation may also damage other components, further increasing maintenance costs and production risks. Therefore, we propose an auxiliary device for replacing metal hand molds to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for changing metal hand molds, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for changing a metal hand mold, comprising a connecting seat and a rotating seat installed in the middle of the connecting seat, a connecting rod installed at the top of the rotating seat, a mounting seat fixed at the top of the connecting rod, a metal hand mold disposed at the top of the mounting seat, a positioning seat fixed to the outer wall of the bottom end of the metal hand mold, a collar disposed on the outside of the connecting rod, positioning rods installed at the top of both sides of the collar, a grip sleeve installed at the bottom end of the collar, a first return spring wound around the outside of the connecting rod, through holes opened on both sides of the mounting seat, positioning holes opened on both sides of the positioning seat, and two sets of positioning rods passing through the two sets of through holes on the mounting seat and the two sets of positioning holes on the positioning seat.

[0006] As an improved technical solution, the mounting base has sleeves fixed on both sides of its bottom end, guide rods fixed at opposite ends of the two sets of sleeves, stop rods provided inside the two sets of sleeves, sliding sleeves fixed at the bottom ends of the two sets of stop rods, sliding sleeves sleeved on the outside of the guide rods, pull handles fixed at opposite ends of the two sets of stop rods, and second return springs wound around the outside of the two sets of guide rods.

[0007] As an improved technical solution, the inner wall of the collar is fully fitted with the outer wall of the connecting rod, and the collar and the connecting rod are slidably connected.

[0008] As an improved technical solution, the first return spring is connected at both ends to the outer wall of the top of the rotating seat and the outer wall of the bottom of the collar, respectively, and the collar is elastically connected to the rotating seat through the first return spring.

[0009] As an improved technical solution, multiple sets of anti-slip rubber strips are installed at equal intervals on the outer wall of the grip sleeve.

[0010] As an improved technical solution, the diameters of the two sets of positioning rods are the same as the inner diameters of the two sets of positioning holes on the positioning seat, and both sets of positioning rods can be inserted into the two sets of sleeves on the positioning seat.

[0011] As an improved technical solution, the outer walls of both sets of stop bars are polished.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are:

[0013] I. This utility model involves installing an mounting base on a connecting seat and then installing a positioning seat on the bottom of a metal hand mold. The grip sleeve moves the collar and two sets of positioning rods on the collar downwards along the surface of the connecting rod, allowing the two sets of positioning rods to quickly disengage from the two sets of positioning holes on the positioning seat. This allows the two sets of positioning rods to quickly release the lock on the positioning seat. By pushing the metal hand mold laterally, the metal hand mold pulls the positioning seat out of the mounting base. The positioning seat on the replacement metal hand mold is then inserted into the mounting base, allowing the first return spring on the outside of the connecting rod to release its elasticity and push the collar upwards vertically along the connecting rod. This allows the two sets of positioning rods on the collar to quickly insert into the two sets of positioning holes on the positioning seat, locking the positioning seat in place. This allows for quick replacement of the metal hand mold without the need for specific tools, reducing disassembly difficulty and improving the ease of use of the device.

[0014] II. This utility model features horizontally movable stop bars installed on both sides of the bottom of the mounting base. When the two sets of stop bars are completely disengaged from the two sets of through holes on the mounting base, the sliding sleeves outside the two sets of stop bars can move in opposite directions under the elastic force of the two sets of second return springs, allowing one end of the two sets of stop bars to move directly below the two sets of through holes. This forms a blockage at the bottom of the two sets of through holes, preventing the two sets of positioning rods on the collar from entering the two sets of through holes. This frees up a hand to replace the metal hand mold without the need for continuous manual pulling of the grip sleeve, thus further improving the convenience of using the device.

[0028] Figures 1 to 7 As shown, this embodiment provides an auxiliary device for changing a metal hand mold, including a connecting seat 1 for mounting the device as a whole on an external transport machine and a rotating seat 2 installed in the middle of the connecting seat 1. A connecting rod 3 is installed at the top of the rotating seat 2, and a mounting seat 4 is fixed at the top of the connecting rod 3. A metal hand mold 5 is provided at the top of the mounting seat 4, and a positioning seat 6 is fixed to the outer wall of the bottom end of the metal hand mold 5. A collar 7 is provided on the outside of the connecting rod 3, and positioning rods 8 are installed at the top of both sides of the collar 7. A grip 9 is installed at the bottom end of the collar 7. A first return spring 10 is wound around the outside of the connecting rod 3. Through holes 11 are opened on both sides of the mounting seat 4, and positioning holes 12 are opened on both sides of the positioning seat 6. The two sets of positioning rods 8 pass through the two sets of through holes 11 on the mounting seat 4 and the two sets of positioning holes 12 on the positioning seat 6.

[0029] When the metal hand mold 5 needs to be replaced, the grip sleeve 9 can be pushed downwards, causing the grip sleeve 9 to move the collar 7 and the two sets of positioning rods 8 on the collar 7 downwards along the surface of the connecting rod 3. This allows the two sets of positioning rods 8 to quickly leave the two sets of positioning holes 12 on the positioning seat 6, thus quickly releasing the lock on the positioning seat 6. Then, by pushing the metal hand mold 5 laterally, the metal hand mold 5 can pull the positioning seat 6 out of the mounting base 4. The positioning seat 6 on the replacement metal hand mold 5 can then be inserted into the mounting base 4. Afterwards, the force on the grip sleeve 9 is released, allowing the first return spring 10 outside the connecting rod 3 to release its elasticity and push the collar 7 to move vertically upwards along the connecting rod 3. This allows the two sets of positioning rods 8 on the collar 7 to quickly insert into the two sets of positioning holes 12 on the positioning seat 6, completing the lock on the positioning seat 6. This allows the metal hand mold 5 to be replaced quickly without the need for specific tools, improving the convenience of using the device.

[0030] In other embodiments, sleeves 13 are fixed on both sides of the bottom end of the mounting base 4, guide rods 14 are fixed on opposite ends of the two sets of sleeves 13, stop rods 15 are provided inside the two sets of sleeves 13, sliding sleeves 16 are fixed at the bottom end of the two sets of stop rods 15, the two sets of sliding sleeves 16 are sleeved on the outside of the guide rods 14, pull handles 17 are fixed on opposite ends of the two sets of stop rods 15, and a second return spring 18 is wound around the outside of the two sets of guide rods 14.

[0031] When the grip 9 is pushed upwards, causing the collar 7 to move the two sets of grips 9 away from the two sets of positioning holes 12 on the positioning seat 6, and then continues to move downwards, the two sets of stop rods 15 are completely disengaged from the two sets of through holes 11 on the mounting seat 4. The sliding sleeves 16 outside the two sets of stop rods 15 can then move in opposite directions under the elastic force of the two sets of second return springs 18, causing one end of the two sets of stop rods 15 to move directly below the two sets of through holes 11. This forms a blockage at the bottom of the two sets of through holes 11, preventing the two sets of positioning rods 8 on the collar 7 from entering. Inside the two sets of through holes 11, the metal hand mold 5 can be replaced without having to continuously pull the grip sleeve 9. When the metal hand mold 5 drives the positioning seat 6 into the mounting base 4, the handle 17 on the outside of the two sets of stop rods 15 can be pulled to move the two sets of stop rods 15 away from directly below the two sets of through holes 11. This allows the collar 7 to drive the two sets of positioning rods 8 to quickly insert into the two sets of through holes 11 on the mounting base 4 and through the two sets of positioning holes 12 on the positioning seat 6, thereby further improving the convenience of using the device.

[0032] In other embodiments, the inner wall of the collar 7 is fully fitted with the outer wall of the connecting rod 3, and the collar 7 and the connecting rod 3 are slidably connected.

[0033] With this design, when the collar 7 moves vertically along the surface of the connecting rod 3, it can effectively ensure that the collar 7 can drive the two sets of positioning rods 8 to move smoothly vertically, so that the two sets of positioning rods 8 can quickly leave or enter the two sets of through holes 11 on the mounting base 4.

[0034] In other embodiments, the first return spring 10 is connected at both ends to the outer wall of the top end of the rotating base 2 and the outer wall of the bottom end of the collar 7, respectively, and the collar 7 is elastically connected to the rotating base 2 through the first return spring 10;

[0035] This design allows the first return spring 10 to continuously apply an upward elastic force to the collar 7, enabling the two sets of positioning rods 8 on the positioning rod 8 to be quickly inserted into the two sets of through holes 11 on the mounting base 4.

[0036] In other embodiments, multiple sets of anti-slip rubber strips are installed at equal intervals on the outer wall of the grip sleeve 9;

[0037] This design effectively increases the friction between the grip 9 and the user's hand when the hand holds the grip 9, making it easier to pull the positioning rod 8 with less effort.

[0038] In other embodiments, the diameters of the two sets of positioning rods 8 are the same as the inner diameters of the two sets of positioning holes 12 on the positioning seat 6, and both sets of positioning rods 8 can be inserted into the two sets of sleeves 13 on the positioning seat 6.

[0039] With this design, when the two sets of positioning rods 8 are inserted into the two sets of positioning holes 12 on the positioning seat 6, the two sets of positioning rods 8 can be effectively prevented from shaking in the sleeve 13, so that the two sets of positioning rods 8 can form a stable moving limit effect on the positioning seat 6, thereby ensuring the stability of the positioning seat 6 during use.

[0040] In other embodiments, the outer walls of both sets of stop bars 15 are polished;

[0041] This design effectively reduces the friction between the stop bar 15 and the outside environment, thereby preventing the two sets of stop bars 15 from causing significant wear on the outer walls of the collar 7 and the positioning rod 8, and extending the service life of the device.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
