Description

Technical Field

[0001] The invention relates to the technical field of molds, in particular to a split-type inclined top core-pulling block for an injection mold. Background Art

[0002] Mold core pulling is used to deal with the position on the parting surface of the product that cannot be demolded. It belongs to the "underhook processing system" and is a structure of the mold. The definition of core pulling is: a mechanism that ensures the smooth demolding of the product, also called a slider. For example, if there is a hole on the side of the product, after the mold is opened, if the core of this hole is not pulled out, the product cannot be ejected. At this time, the mold structure must adopt a slider structure, and the core in the hole is made movable. The inclined guide column is used to cooperate with the fixed mold. The slider moves with the mold opening or closing. This movement is called core pulling. In the inclined top core pulling, it is generally divided into two categories: integral inclined top and non-integral inclined top. The non-integral inclined top can also be called combined inclined top or split inclined top;

[0003] The split inclined top core pulling block of the injection mold is a device used in the injection mold. When the injection mold is in use, the interior is not a single solid injection. When it is necessary to inject a part with a hollow surface or a penetrating interior, the part can be molded out by inserting the core pulling block in the mold.

[0004] In order to solve the problem of reduced mold precision caused by repeated disassembly of the inclined top core pulling block in the prior art, the number of times the inclined top core pulling block is processed is reduced by cooperating among the core, the straight tube core block and the inclined top core pulling block. In addition, the split inclined top core pulling block of the injection mold in the prior art is not convenient for making the inclined top core pulling block. The traditional core pulling blocks are all positive core pulling blocks, and the beveled grooves cannot be made inside the mold, making it impossible to adjust the angle of the inclined top body when the inclined top core pulling block is used, resulting in the need to design the angle when installing the inclined top body, which delays work efficiency.

The inner surface of the snap-fit ​​groove 256 is provided with a matching block 254, and one end of the block 254 extends to the inside of the slide groove 1 251 and is fixedly connected to the slider 1 253. The snap-fit ​​groove 256 is designed as an annular structure and matches the block 254. There are several blocks 254. The blocks 254 are made of metal material. The auxiliary fixing component 26 includes teeth 261, a fixing rod 262, a slide groove 263, a slider 264, and a reset spring 265. The outer surface of the third disc 14 is fixedly connected with teeth 261 at equal distances in an annular manner. The upper end surface of the push rod 1 is symmetrically provided with a fixing rod 262 at a position corresponding to the third disc 14.The upper end surface of the push rod 1 is symmetrically provided with a second slide groove 263 at a position corresponding to the fixed rod 262. The inner surface of the second slide groove 263 is slidably connected with a second slider 264 that matches each other, and the upper end surface of the slider 264 is fixedly connected with the lower end of the fixed rod 262.

The upper end of the fixed rod 262 is engaged with the tooth 261 on the outer surface of the third disk 14 through the tooth.

[0039] By adopting the above technical solution, based on the above embodiment, when the user wants to adjust the angle of the inclined top body 11, the user must first turn off the power of the annular structure electromagnet 24 located inside the third disk 14 and embedded in the corresponding positions of the engaging mechanism 25 on the first disk 21 and the second disk 22. The electromagnet 24 loses its magnetic force, and at the same time, the force stored in the return spring 252 located inside the slide groove 251 in the stretched state will pull the block 254 back into the annular groove 255. At this time, the block 254 is separated from the engaging groove 256, and the free end of the block 254 is located in the annular groove 255. The guide groove 1 257 cooperates with the slider 1 253 to ensure that the block 254 is stably horizontally displaced into the annular groove 255. At this time, the fixed rod 262 will also pull the slider 264 to displace in the opposite direction inside the slide groove 263 when the return spring 265 is in a stretched state, so that the upper end teeth of the fixed rod 262 fixedly connected to the slider 264 are separated from the teeth 261 on the outer surface of the third disk 14. Then the user can rotate the third disk 14 to a suitable angle and turn on the power of the electromagnet 24. The electromagnet 24 will generate magnetic force, thereby adsorbing the metal material. The card block 254 enters the corresponding card slot 256 from the annular groove 255. At this time, the reset spring 1 252 will be in a stretched state again, waiting for the next use. At the same time, the electromagnet 24 conducts electricity to generate magnetic force, which will also attract the fixing rod 262 which is also made of metal material, and the fixing rod 262 will move toward the third disk 14 through the matching slider 263 and the slide groove 264 until the teeth at the upper end of the fixing rod 262 are engaged between the teeth 261 on the outer surface of the third disk 14, and the upper end surface of the top rod 1 The symmetrically fixed pad 13 on the third disk 1 The teeth 261 on the outer surface are separated from the push rod 1, thereby avoiding friction between the teeth 261 and the push rod 1. The design of the device structure can not only generate magnetic force by turning on and off the electromagnet 24 to drive the engaging mechanism 25 to operate and further limit the angle of the hollow tube 12 and the inclined top body 11 passing through the angle adjustment mechanism 2, but also drive the auxiliary fixing component 26 to assist in supporting the third disk 14 at the main force point, share the impact force of the inclined top body 11 on the third disk 14 during subsequent use, thereby reducing the probability of damage to the engaging mechanism 25 and ensuring the service life of the angle adjustment mechanism 2.

[0040] As an embodiment of the present invention, Figure 5 and Figure 6As shown, the disassembly mechanism 3 includes an inner shaft 31, a metal rope 32, a guide tube 33, a guide block 34, a metal spring 35, a second guide groove 36, and a connector 111. The inner shaft 31 is arranged inside the outer shaft 23, and the two ends of the inner shaft 31 are fixedly connected to the first disc 21 and the second disc 22. The upper end of the hollow tube 12 is integrally connected with the metal spring 35. The outer surface of the hollow tube 12 is fixedly connected with the guide tube 33 at a position corresponding to the metal spring 35. The guide tube 33 is provided with a second guide groove 36 inside, and the inner surface of the second guide groove 36 is slidably connected with the corresponding guide groove 36. The guide blocks 34 are matched with each other, and the outer surface of the inner shaft 31 is fixedly connected with a metal rope 32, and one end of the metal rope 32 extends to the upper end of the third disc 14 through a channel opened inside the third disc 14 and is fixedly connected to the lower end surface of the guide block 34. The connector 111 is threadedly connected to the hollow tube 12 and the metal spring 35. The guide blocks 34 and the metal spring 35 are each in three groups, and they are distributed in a ring shape at equal distances on the outer surface of the hollow tube 12. The metal rope 32 is made of ductile metal material, and the upper end of the metal rope 32 is divided into three strands and fixedly connected to the lower end surfaces of the three groups of guide blocks 34 respectively.

[0041] By adopting the above technical solution and based on the above embodiments, different inclined top bodies 11 are needed for different products. If the inclined top body 11 needs to be disassembled and replaced, the user must first pull out the guide block 34 from the guide groove 36. During the pulling out process, the extrusion force of the metal spring piece 35 integrally connected to the upper end of the hollow tube 12 on the plug-in connector 111 will gradually decrease until it is zero. Because the plug-in connector 111 is threadedly connected to the hollow tube 12 and the metal spring piece 35, and is integrally connected to the upper end of the hollow tube 12, after the extrusion force of the metal spring piece 35 on the hollow tube 12 is zero, the plug-in connector 111 can be screwed out in the opposite direction and replaced with a suitable inclined top body. After the angle adjustment mechanism 2 is adjusted, the metal rope 32 fixedly connected to the inner shaft 31 will be wound around the outer surface of the inner shaft 31, thereby forcing the metal rope 32 to pull the guide block 34 located inside the guide groove 36 downward, and by increasing the squeezing force of the guide block 34 on the metal spring piece 35, the metal spring piece 35 cooperates with the threaded connection part at the upper end of the hollow tube 12 to firmly lock and fix the connector 111, thereby fixing the inclined top body 11, and preventing the inclined top body 11 from falling off and loosening due to force after the angle adjustment.

[0042] Working principle: When the user wants to adjust the angle of the inclined top body 11, the user must first turn off the power of the annular structure electromagnet 24 located inside the third disk 14 and embedded in the corresponding positions of the engaging mechanisms 25 on the first disk 21 and the second disk 22. The electromagnet 24 loses its magnetic force, and at the same time, the force stored in the return spring 1 252 located inside the slide groove 1 251 in the stretched state will pull the block 254 back to the annular groove 255. At this time, the block 254 is separated from the engaging groove 256, and the guide groove 1 257 cooperates with the slider 1 253 to ensure that the block 254 is stably horizontally displaced into the annular groove 255. At this time, the fixing rod 262 will also pull the slider 264 in the slide groove 263 when the return spring 265 is in the stretched state. The inner part is displaced in the opposite direction, so that the upper end teeth of the fixing rod 262 fixedly connected to the slider 264 are separated from the outer surface of the third disk 14. Then the user can rotate the third disk 14. After turning it to a suitable angle, turn on the power of the electromagnet 24. The electromagnet 24 will generate magnetic force, and then absorb the card block 254 made of metal material, and enter the corresponding card groove 256 from the annular groove 255. At this time, the reset spring 1 252 will be in a stretched state again, waiting for the next use. At the same time, the electromagnet 24 conducts electricity to generate magnetic force, which will also attract the fixing rod 262 which is also made of metal material, and the fixing rod 262 will move toward the third disk 14 through the matching slider 263 and the slide groove 264 until the fixing rod 262 is on The teeth at the end are engaged between the teeth 261 on the outer surface of the third disk 14, and the pad 13 symmetrically fixed on the upper end surface of the push rod 1 will separate the teeth 261 on the outer surface of the third disk 14 from the push rod 1, avoiding friction between the teeth 261 and the push rod 1. The design of the device structure can not only generate magnetic force through the on-off power of the electromagnet 24 to drive the engaging mechanism 25 to operate to further limit the angle of the hollow tube 12 and the inclined top body 11 passing through the angle adjustment mechanism 2, but also drive the auxiliary fixing component 26 to assist in supporting the third disk 14 at the main force point, share the impact force of the inclined top body 11 on the third disk 14 during subsequent use, and thereby reduce the probability of damage to the engaging mechanism 25. The device needs to be used for different products. Different inclined top bodies 11 need to be disassembled and replaced, so the user must first pull out the guide block 34 from the second guide groove 36. During the pulling out process, the extrusion force of the metal spring 35 integrally connected to the upper end of the hollow tube 12 on the plug-in connector 111 will gradually decrease until it is zero. Because the plug-in connector 111 is threadedly connected to the hollow tube 12 and the metal spring 35, and is integrally connected to the upper end of the hollow tube 12, after the extrusion force of the metal spring 35 on the hollow tube 12 is zero, the plug-in connector 111 can be unscrewed in the opposite direction, and after replacing the appropriate inclined top body 11, the plug-in connector 111 can be screwed back, and then the guide block 34 can be pressed back into the matching guide groove 36 until it can no longer be pressed in.The metal rope 32 fixedly connected to the inner shaft 31 will be wound around the outer surface of the inner shaft 31 when the angle adjustment mechanism 2 adjusts the angle, increasing the squeezing force of the guide block 34 on the metal spring 35, thereby forcing the metal rope 32 to pull the guide block 34 located inside the second guide groove 36 downward. By increasing the squeezing force of the guide block 34 on the metal spring 35, the metal spring 35 cooperates with the threaded connection part at the upper end of the hollow tube 12 to firmly lock the fixed connector 111, thereby fixing the inclined top body 11, and preventing the inclined top body 11 from falling off and loosening due to force after the angle adjustment.
