Abstract
Description
Technical Field
[0001] This utility model relates to the field of ejector support technology, and in particular to a molding machine that facilitates the removal of the molding grinding wheel. Background Technology
[0002] A molding machine that facilitates the removal of molding grinding wheels refers to a specialized piece of equipment that optimizes the grinding wheel demolding process, reduces manual intervention, improves operational efficiency, and ensures product quality through specific structural or functional designs.
[0003] For example, publication number CN221495668U discloses a forming machine for easy removal of formed grinding wheels. The machine includes a worktable with two symmetrically distributed door panels on its front side, each with a handle. A mounting frame is mounted on the upper surface of the worktable, with sliding columns on both sides of the mounting frame. A sliding plate is slidably mounted between the outer arc surfaces of the two sliding columns. An upper mold is mounted on the lower surface of the sliding plate. A forming platform is mounted on the upper surface of the worktable, with a lower mold on its upper surface. A pushing module for pushing materials is also mounted on the forming platform. An electric drive module for moving the sliding plate is also located between the mounting frame and the sliding plate. With this forming machine, the formed grinding wheel is quickly ejected by the pushing module after forming, facilitating its removal.
[0004] In the aforementioned patent, the motor operation is controlled via a control panel, causing the bidirectional lead screw to drive the adjusting sliders on both sides to move in opposite directions within the guide groove. This causes the adjusting sliders to rotate via a connecting rod, which in turn drives the drive plate to rise via a dovetail slider. The drive plate then drives the top support column to rise. However, the bidirectional lead screw and adjusting slider are prone to wear after long-term operation, resulting in transmission gaps. This can cause the top support column to lag or deviate in movement, posing a risk of transmission gaps or jamming, and affecting demolding accuracy. Therefore, a molding machine that facilitates the removal of the molding grinding wheel is needed to enable quick removal of the molding grinding wheel. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing molding machines that facilitate the removal of the molding grinding wheel. These machines rely on a two-way lead screw and an adjusting slider, which are prone to wear after long-term operation, resulting in transmission gaps and causing lag or displacement deviation in the movement of the top support column. Therefore, this invention proposes a molding machine that facilitates the removal of the molding grinding wheel.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a forming machine that facilitates the removal of forming grinding wheels, comprising a control body, a hydraulic cylinder, and an upper mold.

A top plate is fixedly connected to the top end of the connecting plate, and a central shaft is fixedly connected to the top end of the top plate. The arc surface of the top plate is slidably connected to the lower mold.

[0009] The effect achieved by the above components is that the cylinder is fixed on the support base.
[0010] Preferably, the cylinder has four round rods slidably connected inside, and one end of each of the four round rods is fixedly connected to the top plate.
[0011] The effect achieved by the above components is that the movement of the top plate causes the round rod to slide inside the cylinder.
[0012] Preferably, one end of each of the four round rods is fixedly connected to a connecting ring.
[0013] The effect achieved by the above components is that the connecting ring is fixed on the round rod.
[0014] Preferably, the arc surface of the round rod is fitted with a spring, and the two ends of the four springs are respectively fixedly connected to the connecting ring and the support base.
[0015] The effect achieved by the above components is that the movement of the round rod drives the adjustment of the position of the connecting ring, causing the spring to contract or stretch.
[0016] Preferably, the control unit is provided with a heat dissipation device on its exterior. The heat dissipation device includes an L-shaped plate, one end of which is fixedly connected to the control unit, and a cooling fan is fixedly connected to one side of the L-shaped plate.

[0020] Preferably, the short arm end of the L-shaped plate is fixedly connected to a stabilizing frame.
[0021] The effect achieved by the above components is to securely fix the frame to the L-shaped plate.
[0022] Preferably, a stabilizing plate is fixedly connected to one side of the stabilizing frame, and one side of the stabilizing plate is fixedly connected to the control body.

[0024] In summary, the beneficial effects of this utility model are as follows:
[0025] In this invention, when the forming grinding wheel needs to be removed, the cylinder is activated by the ejection device. The cylinder output pushes the connecting plate to move, causing the top plate to slide in the lower mold and eject the forming grinding wheel from the lower mold. The ejection device solves the problem that traditional forming machines that facilitate the removal of forming grinding wheels rely on bidirectional lead screws and adjusting sliders, which are prone to wear after long-term operation, forming transmission gaps and causing the top support column to move lag or have displacement deviation.
[0026] In this invention, a cooling fan is activated when the removed forming grinding wheel needs to be cooled, and the generated cold airflow is output through the port to cool the forming grinding wheel placed on the L-shaped plate. The cooling device solves the problem that traditional forming machines, which are easy to remove, are not convenient for cooling the forming grinding wheel. The grinding wheel is at a high temperature after forming, and if it is not cooled in time, residual stress is easily generated inside due to thermal expansion and contraction, which can lead to cracking and deformation of the grinding wheel.

[0034] The specific setup and function of its ejector device 2 and heat dissipation device 3 will be explained below.
[0035] Reference Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment: the ejection device 2 includes a circular plate 201, the bottom end of which is fixedly connected to the control body 1, and a support base 212 fixedly connected to the top end of the circular plate 201. A flange hole 204 is provided at the top end of the support base 212, and a lower mold 207 is fixedly connected to the top end of the support base 212. A cylinder 202 is fixedly connected to the top end of the circular plate 201, and a connecting plate 203 is fixedly connected to the output end of the cylinder 202. A top plate 205 is fixedly connected to the top end of the connecting plate 203, and a central shaft 206 is fixedly connected to the top end of the top plate 205. The arc surface of the top plate 205 is slidably connected to the lower mold 207. This achieves the effect of the cylinder 202 starting, driving the connecting plate 203 to move, thus adjusting the position of the top plate 205 within the lower mold 207. Four cylinders 208 are fixedly connected to the top end of the support base 212, achieving the effect of the cylinders 208 being fixed on the support base 212. Inside the cylinder 208, four round rods 209 are slidably connected, with one end of each rod fixedly connected to the top plate 205. This achieves the effect of the top plate 205 moving to slide the round rods 209 within the cylinder 208. One end of each of the four round rods 209 is fixedly connected to a connecting ring 211, ensuring the connecting ring 211 is fixed to the round rod 209. Springs 210 are fitted onto the arcuate surface of each round rod 209, with both ends of the four springs 210 fixedly connected to the connecting ring 211 and the support base 212, respectively. This achieves the effect of the round rods 209 moving to adjust the position of the connecting ring 211, causing the springs 210 to contract or extend.
[0036] Reference Figure 4As shown in this embodiment: the heat dissipation device 3 includes an L-shaped plate 31, one end of which is fixedly connected to the control body 1, and a cooling fan 32 is fixedly connected to one side of the L-shaped plate 31. This achieves the effect of the cooling fan 32 being fixed to the L-shaped plate 31, and the L-shaped plate 31 being fixed to the control body 1. A limiting plate 33 is fixedly connected to one end of the L-shaped plate 31, and four openings 36 are provided on the long arm end of the limiting plate 33. This achieves the effect of the limiting plate 33 being fixed to the L-shaped plate 31, and the openings 36 being provided on the L-shaped plate 31. A stabilizing frame 35 is fixedly connected to the short arm end of the L-shaped plate 31. This achieves the effect of the stabilizing frame 35 being fixed to the L-shaped plate 31. A stabilizing plate 34 is fixedly connected to one side of the stabilizing frame 35, and one side of the stabilizing plate 34 is fixedly connected to the control body 1. This achieves the effect of the stabilizing frame 35 being fixed to the stabilizing plate 34, and the stabilizing plate 34 being fixed to the control body 1.
[0037] Working Principle: When the formed grinding wheel needs to be removed via the ejector device 2, the operator first adds the raw material for producing the grinding wheel into the lower mold 207. The output of the hydraulic cylinder 4 is adjusted by the control body 1 to drive the upper mold 5 to move towards the lower mold 207. The upper mold 5 and the lower mold 207 cooperate to press and form the grinding wheel. After forming, the output of the hydraulic cylinder 4 is adjusted to retract, releasing the upper mold 5 from its restriction on the lower mold 207, creating operating space for removing the formed grinding wheel. The control body 1 then activates the cylinder 202, whose output pushes the connecting plate 203 to move, causing the top plate 205 to slide within the lower mold 207, thus removing the grinding wheel. The forming grinding wheel is ejected from the lower mold 207. During this process, the movement of the top plate 205 causes the round rod 209 to slide inside the cylinder 208. The connecting ring 211 synchronously drives the spring 210 to contract and store energy. After the forming grinding wheel is removed, the output end of the cylinder 202 retracts. At this time, the spring 210 releases its elastic potential energy, assisting the top support column to quickly reset, reducing the reset resistance of the pneumatic system and reducing energy consumption. Through the ejection device 2, the problem of traditional forming machines that facilitate the removal of forming grinding wheels, which rely on bidirectional lead screws and adjusting sliders, are prone to wear after long-term operation, forming transmission gaps, resulting in lag or displacement deviation of the top support column.
[0038] With the heat dissipation device 3, when it is necessary to cool down the removed forming grinding wheel, the operator first controls the cooling fan 32 to start by controlling the machine body 1. The cold air generated by the fan is output through the port 36, and the forming grinding wheel is placed on the L-shaped plate 31. This ensures that the cold air is continuously blown onto the surface of the grinding wheel through the port 36 on the L-shaped plate 31, thereby achieving continuous cooling of the forming grinding wheel. The heat dissipation device 3 solves the problem that traditional forming machines, which are easy to remove, are not convenient for cooling the forming grinding wheel. After the grinding wheel is formed, the temperature is high. If it is not cooled in time, residual stress is easily generated inside due to thermal expansion and contraction, which can lead to cracking and deformation of the grinding wheel.
