Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a processing mold with an ejection mechanism. Background Technology

[0002] In industrial production, molds are various molds and tools used to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, and stamping. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the processing of the shape of the object by changing the physical state of the material being molded. It is known as the "mother of industry". Since the raw material is formed in the mold, the raw material will stick tightly to the inner wall of the mold and is difficult to discharge. Therefore, an ejector mechanism is needed to complete the discharge operation.

[0003] Existing mold ejection structures typically eject raw materials directly from the bottom of the mold during use. However, these structures lack any mechanism to detect whether the raw materials have fully cooled. This means that if the raw materials are not fully cooled and stick to the inner wall of the mold, forcibly ejecting them can cause them to break inside the mold, directly affecting the molding quality. There is room for improvement in this regard. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a processing mold with an ejection mechanism.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A processing mold with an ejection mechanism includes a processing table, an industrial control host fixedly connected to the front of the processing table, a lower mold fixedly connected to the upper surface of the processing table, a support plate slidably connected to the inner wall of the lower mold, and an ejection assembly fixedly connected to the inner bottom wall of the processing table. The ejection assembly includes an electric push rod, a strip plate fixedly connected to the output end of the electric push rod, a positioning block fixedly connected to the upper surface of the strip plate, a pressure sensor fixedly connected to the upper surface of the positioning block, four sleeves fixedly connected to the upper surface of the strip plate, buffer springs fixedly connected to the inner bottom walls of the four sleeves, a movable plate slidably connected to the inner wall of the sleeves, a push rod fixedly connected to the upper surface of the movable plate, and a contact plate fixedly connected to the top end of the push rod.

[0007] A positioning plate is fixedly connected to the left side of the processing table by mounting bolts. A fan is fixedly connected to the left side of the positioning plate. An air inlet pipe is connected to the input end of the fan, and a connecting pipe is connected to the output end of the fan. An air inlet is connected to the left side of the lower mold. A cooling cavity is opened inside the lower mold. A heat-conducting plate is fixedly connected to the inner wall of the cooling cavity. Several heat dissipation holes are opened on the upper surface of the lower mold.

[0008] Preferably, the upper surface of the processing table is provided with a strip-shaped hole adapted to the strip plate, and the position of the strip plate corresponds to the position of the support plate.

[0009] Preferably, the four sleeves are evenly distributed on the upper surface of the strip plate, and the upper surfaces of the four contact plates are fixedly connected to the lower surface of the pallet. The four contact plates can be evenly distributed below the pallet, so there will be no problem of center of gravity shift when the pallet is lifted upward.

[0010] Preferably, the end of the buffer spring away from the inner bottom wall of the sleeve is fixedly connected to the lower surface of the movable plate, and the top end of the sleeve is provided with a circular hole that matches the push rod. The movable plate can move downward and compress the spring to cause it to deform.

[0011] Preferably, the end of the connecting pipe away from the fan is connected to the inner wall of the air inlet, so that the cold air blown out by the fan can be blown into the cooling chamber through the connecting pipe and the air inlet.

[0012] Preferably, the position of the heat dissipation hole corresponds to the position of the cooling cavity. After the cold air blows into the cooling cavity, it can drive the heat in the cooling cavity to be discharged through the heat dissipation hole.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By setting the ejection component, the pallet can be pre-ejected. The buffer spring and pressure sensor automatically detect whether the raw material has been completely cooled in the lower mold. When the raw material has not been completely cooled, the pallet can generate resistance and press down on the pressure sensor. When the pressure sensor generates pressure data and reaches the preset threshold, the industrial control host can automatically shut off the electric push rod to avoid the problem of raw material breakage caused by forced ejection, thus providing good protection for the raw material.

[0015] 2. Through the configuration of the fan, connecting pipe, air inlet, cooling chamber, heat conduction plate and heat dissipation holes, cold air can be blown directly into the cooling chamber during use. The heat conduction plate can absorb the heat in the lower mold and dissipate it quickly by blowing cold air onto the surface of the heat conduction plate, thereby improving the cooling efficiency of the raw materials.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1, referring to Figure 1 , Figure 2 and Figure 3 A processing mold with an ejection mechanism includes a processing table 1, an industrial control host 2 fixedly connected to the front of the processing table 1, a lower mold 3 fixedly connected to the upper surface of the processing table 1, a support plate 4 slidably connected to the inner wall of the lower mold 3, an ejection assembly fixedly connected to the inner bottom wall of the processing table 1, the ejection assembly including an electric push rod 5, a strip plate 6 fixedly connected to the output end of the electric push rod 5, a strip hole adapted to the strip plate 6 opened on the upper surface of the processing table 1, and the position of the strip plate 6 corresponds to the position of the support plate 4, a positioning block 7 fixedly connected to the upper surface of the strip plate 6, and a pressure sensor 8 fixedly connected to the upper surface of the positioning block 7;

[0023] Four sleeves 9 are fixedly connected to the upper surface of the strip plate 6. The four sleeves 9 are evenly distributed on the upper surface of the strip plate 6. A buffer spring 10 is fixedly connected to the inner bottom wall of each of the four sleeves 9. A movable plate 11 is slidably connected to the inner wall of the sleeve 9. The end of the buffer spring 10 away from the inner bottom wall of the sleeve 9 is fixedly connected to the lower surface of the movable plate 11. A top rod 12 is fixedly connected to the upper surface of the movable plate 11. A circular hole adapted to the top rod 12 is opened at the top of the sleeve 9. A contact plate 13 is fixedly connected to the top of the top rod 12, and the upper surfaces of the four contact plates 13 are fixedly connected to the lower surface of the support plate 4.

[0024] After the raw material is formed in the lower mold 3, the electric push rod 5 is activated by the industrial control host 2. The electric push rod 5 can drive the strip plate 6 to rise. The strip plate 6 can drive the push rod 12 and the contact plate 13 to rise through the sleeve 9. The four contact plates 13 are evenly distributed under the support plate 4, so the support plate 4 can rise vertically without causing the center of gravity to shift. When the contact plates 13 lift the support plate 4, the buffer spring 10 will be under pressure and deform to a certain extent. When the raw material is completely cooled, it will not stick to the lower mold 3. Therefore, the deformation amplitude of the buffer spring 10 is small and will not drive the support plate 4 to rise vertically. Pressure sensor 8 generates pressure data, which can directly push the raw material out. When the raw material is not completely cooled, the resistance of the contact plate 13 in lifting the support plate 4 is relatively large. At this time, the movable plate 11 presses the buffer spring 10 downward to increase the deformation amplitude, which will cause the support plate 4 to contact the pressure sensor 8 and press the pressure sensor 8 downward to generate pressure data. When the pressure data on the pressure sensor 8 exceeds the preset threshold, the industrial control host 2 automatically determines that the raw material is not completely cooled and shuts off the electric push rod 5 to avoid the raw material from being broken by direct ejection, thus providing better protection for the raw material.

[0025] Example 2: Refer to Figure 1 and Figure 4 A positioning plate 15 is fixedly connected to the left side of the processing table 1 by mounting bolts 14. A fan 16 is fixedly connected to the left side of the positioning plate 15. An air inlet pipe 17 is connected to the input end of the fan 16, and a connecting pipe 18 is connected to the output end of the fan 16. An air inlet 19 is connected to the left side of the lower mold 3. The end of the connecting pipe 18 away from the fan 16 is connected to the inner wall of the air inlet 19. A cooling cavity 20 is opened inside the lower mold 3. A heat-conducting plate 21 is fixedly connected to the inner wall of the cooling cavity 20. Several heat dissipation holes 22 are opened on the upper surface of the lower mold 3. The positions of the heat dissipation holes 22 correspond to the positions of the cooling cavity 20.

[0026] The fan 16 can blow cold air into the cooling chamber 20 through the connecting pipe 18 and the air inlet 19. Since the heat-conducting plate 21 is in contact with the inner wall of the cooling chamber 20, the heat in the lower mold 3 will accumulate on the heat-conducting plate 21. The cold air blows directly onto the surface of the heat-conducting plate 21 in the cooling chamber 20, which can quickly dissipate the heat through the heat dissipation hole 22, thereby quickly reducing the temperature inside the lower mold 3, allowing the raw material to be quickly formed and separated from the inner wall of the lower mold 3, thus avoiding the situation where the raw material sticks to the lower mold 3 and breaks.

[0027] Working principle: After the raw material is formed in the lower mold 3, the electric push rod 5 is opened by the industrial control host 2. The electric push rod 5 drives the strip plate 6 to rise. The strip plate 6 then drives the ejector rod 12 and the contact plate 13 to rise through the sleeve 9, thereby driving the support plate 4 to rise. When the raw material is completely formed and cooled in the lower mold 3, the buffer spring 10 does not need to undergo a large deformation to drive the support plate 4 to rise, thus ejecting the raw material. When the raw material is not completely cooled and sticks to the inner wall of the lower mold 3, the ejector rod 12 encounters greater resistance during the upward movement of the contact plate 13, which will cause the buffer spring 10 to undergo a large deformation. When the support plate 4 drives the pressure sensor 8 to generate... When the pressure data reaches the preset threshold, the pressure sensor 8 automatically transmits an electrical signal to the industrial control host 2. The industrial control host 2 automatically shuts off the electric push rod 5 and simultaneously turns on the fan 16, causing the fan 16 to blow air into the cooling chamber 20 through the connecting pipe 18 and the air inlet 19. The heat from the inner wall of the lower mold 3 is transferred to the heat-conducting plate 21. The air in the cooling chamber 20 directly dissipates heat from the heat-conducting plate 21 and quickly exhausts the heat through the heat dissipation holes 22, thereby accelerating the cooling speed in the lower mold 3. This ensures that the material is completely cooled before the ejection operation is performed again, thus ensuring the protection of the material and making it more practical.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
