Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an anti-sticking material mold structure. Background Technique

[0002] A stamping die is a special tool for metal processing and is widely used in the manufacturing industries such as automobile manufacturing, household appliance manufacturing, and electronic equipment manufacturing. Stamping processing is to place a metal sheet in a die and then apply pressure to cause plastic deformation or separation of the sheet, so as to obtain the required shape and size.

[0003] After the stamping part is stamped and formed by the lower die of the existing stamping die, the outer wall of the stamping part will fit with the inner wall of the lower die, and the friction between the two is relatively large. The stamping part is directly ejected by the ejection mechanism at the bottom of the lower die. When the friction between the two is relatively large, the ejection mechanism continuously ejects, which easily causes deformation of the lower part of the stamping part, resulting in a decrease in the finished product quality of the stamping part. At the same time, the production efficiency will also decrease due to the sticking of the stamping part. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-sticking material mold structure to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An anti-sticking material mold structure includes:

[0007] A lower die;

[0008] An ejection assembly, fixedly arranged inside the lower die. The ejection assembly includes a support plate fixedly installed on the inner surface of the lower die. A cylinder is fixedly installed on the upper surface of the support plate. The cylinder is movably sleeved with an ejection ring that slidably fits with the lower die;

[0009] A transmission assembly, fixedly installed on the lower surface of the lower die. The transmission assembly includes a cylinder fixedly installed on the lower surface of the lower die through a bracket. An air pump is fixedly installed on the outer surface of the bracket;

[0010] A lubrication assembly; arranged below the lower die.

[0011] Furthermore: The output end of the cylinder is fixedly installed with a U-shaped ejector rod. Symmetrical chutes are opened on one side surface of the support plate. The U-shaped ejector rod slidably penetrates through the chutes and is fixedly connected to the ejection ring.

[0012] Furthermore: An air groove penetrating through its inner wall is opened on the lower surface of the ejection ring. One end of the air groove is fixedly inserted with a first elastic tube. One end of the first elastic tube is fixedly communicated with the air outlet end of the air pump.

[0013] Furthermore, an activity groove is formed on the outer side surface of the ejecting ring, a sealing ring is slidably sleeved inside the activity groove, and a plurality of oil drainage grooves communicating with the activity groove are equiangularly formed on the outer side surface of the ejecting ring.

[0014] Preferably, an oil distribution groove is formed inside the ejecting ring, a plurality of oil outlets of the oil distribution groove communicate with the activity groove, and a penetration block is fixedly installed inside the oil outlet of the oil distribution groove.

[0015] Furthermore, the lubrication assembly includes:

[0016] an oil storage tank fixedly installed on the outer side surface of the bracket of the cylinder;

[0017] a piston plate slidably connected inside the oil storage tank;

[0018] a push rod slidably penetrating through one end surface of the oil storage tank and fixedly connected to the piston plate;

[0019] a motor fixedly installed on one end surface of the oil storage tank.

[0020] Preferably, an oil injection pipe is fixedly communicated with the upper end of the outer side surface of the oil storage tank, a rack is fixedly embedded on the outer side surface of the push rod, a gear meshing with the rack is fixedly installed at the output end of the motor, and a second elastic pipe fixedly communicated with the oil distribution groove is fixedly connected to the upper end of the oil storage tank.

[0021] Compared with the prior art, the beneficial effects of the present utility model are:

[0022] 1. By the extension of the cylinder, the ejecting ring moves upward between the cylinder and the lower die, exposing the air groove. The air pump operates to introduce external air between the ejecting ring and the cylinder, so that the gas continuously pushes the punching machine inside the lower die upward, reducing the direct contact between the ejecting ring and the punched part, thereby avoiding the deformation of the punched part caused by the continuous pushing of the ejecting ring in contact with the punched part, improving the finished product quality of the punched part, and at the same time avoiding the reduction of production efficiency caused by the stuck material of the punched part.

[0023] 2. When the ejecting ring moves upward, under the action of friction, the sealing ring moves from the upper part inside the activity groove to the lower part, exposing the oil outlet of the oil distribution groove. The lubricating oil inside the oil distribution groove penetrates into the space above the sealing ring through the penetration block. When the ejecting ring moves downward, the sealing ring resets, blocking the oil outlet of the oil distribution groove, and at the same time squeezing the lubricating oil to spread from the oil drainage groove to the outer wall above the ejecting ring, lubricating the inner wall of the lower die. Thus, when the ejecting assembly moves up and down, lubricating oil is applied to the inside of the lower die, reducing the friction between the punched part and the lower die, and increasing the sealing performance between the punched part and the lower die through the lubricating oil, reducing the gas leakage, and making it more convenient for the air to push the punched part out.

[0024] 3. The motor operates, driving the rack to drive the ejector rod to move, causing the piston plate to push the lubricating oil above it upward, giving the lubricating oil an upward force so that it can be continuously supplied into the oil distribution groove.

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Please refer to Figures 1 to 5, in the embodiment of the present utility model, a mold structure for preventing material jamming includes: a lower mold 1; an ejection assembly 2 fixedly arranged inside the lower mold 1. The ejection assembly 2 includes a support plate 201 fixedly installed on the inner surface of the lower mold 1. A cylinder 202 is fixedly installed on the upper surface of the support plate 201. An ejection ring 203 that slidably fits with the lower mold 1 is movably sleeved on the cylinder 202; a transmission assembly 3 fixedly installed on the lower surface of the lower mold 1. The transmission assembly 3 includes an air cylinder 301 fixedly installed on the lower surface of the lower mold 1 through a bracket, and an air pump 305 is fixedly installed on the outer surface of the bracket; a lubrication assembly 4 is arranged below the lower mold 1.

[0033] Specifically, the ejection assembly 2 is used to eject the stamping part. The air pump 305 pumps air, and the gas is used to push the stamping part out, reducing the contact between the ejection ring 203 and the stamping part. The lubrication assembly 4 continuously supplies lubricating oil to keep the inner wall of the lower mold 1 smooth.

[0034] Embodiment 1

[0035] As Figure 2 and Figure 3 shown, in this embodiment, a U-shaped ejector rod 302 is fixedly installed at the output end of the air cylinder 301. Symmetric sliding grooves 209 are formed on one side surface of the support plate 201. The U-shaped ejector rod 302 slidably penetrates through the sliding grooves 209 and is fixedly connected to the ejection ring 203; an air groove 304 penetrating through its inner wall is formed on the lower surface of the ejection ring 203. One end of the air groove 304 is fixedly inserted with a first elastic tube 303, and one end of the first elastic tube 303 is fixedly communicated with the air outlet end of the air pump 305.

[0036] In this embodiment, after stamping is completed, the air cylinder 301 extends, driving the U-shaped ejector rod 302 to move upward, so that the ejection ring 203 moves upward between the cylinder 202 and the lower mold 1, exposing the air groove 304. The air pump 305 operates to introduce external air between the ejection ring 203 and the cylinder 202, so that the gas continuously pushes the stamping machine inside the lower mold 1 to move upward, reducing the direct contact between the ejection ring 203 and the stamping part, thereby avoiding the deformation of the stamping part caused by the continuous pushing of the ejection ring 203 in contact with the stamping part, improving the finished product quality of the stamping part, and at the same time avoiding the reduction of production efficiency caused by material jamming of the stamping part.

[0037] As Figures 2 - 4 shown, in this embodiment, a movable groove 204 is formed on the outer surface of the ejection ring 203. A sealing ring 205 is slidably sleeved inside the movable groove 204. A plurality of oil discharge grooves 208 communicating with the movable groove 204 are equiangularly formed on the outer surface of the ejection ring 203. An oil distribution groove 206 is formed inside the ejection ring 203. A plurality of oil outlet ports of the oil distribution groove 206 are all communicated with the movable groove 204, and a penetration block 207 is fixedly installed inside the oil outlet port of the oil distribution groove 206.

[0038] During specific implementation, when the ejection ring 203 moves upward, under the action of friction, the sealing ring 205 moves from the upper part inside the movable groove 204 to the lower part, exposing the oil outlet of the oil distribution groove 206. The lubricating oil inside the oil distribution groove 206 penetrates into the space above the sealing ring 205 through the penetration block 207 and contacts the inner wall of the lower mold 1. When the ejection ring 203 moves downward, the sealing ring 205 resets, blocking the oil outlet of the oil distribution groove 206, and at the same time squeezing the lubricating oil to spread from the oil drain groove 208 to the outer wall above the ejection ring 203 to lubricate the inner wall of the lower mold 1. Thus, when the ejection assembly 2 moves up and down, lubricating oil is applied to the inside of the lower mold 1, reducing the friction between the stamping part and the lower mold 1, and increasing the sealing performance between the stamping part and the lower mold 1 through the lubricating oil, reducing gas leakage, and making it easier for the air to push the stamping part out.

[0042] During specific implementation, the motor 406 operates, driving the gear 408 to rotate, pushing the rack 407 to drive the push rod 404 to move, so that the piston plate 403 pushes the lubricating oil above it upward, giving the lubricating oil an upward force, enabling it to be continuously supplied to the inside of the oil distribution groove 206.
