Description

Technical Field

[0001] The present application relates to the field of glass product production, and in particular to a lifting mechanism for removing glass products. Background Art

[0002] Glass molds are special tools used to make glass products. They are usually made of high-temperature resistant materials and can withstand the high temperatures when the glass is melted. The shape and design of the mold depends on the shape and size of the glass product to be produced.

[0003] The related art discloses a glass mold for making wine bottles, which includes two movable molds that can move relative to each other, and the opposite sides of the two movable molds are provided with molding cavities for forming the wine bottles. When the wine is solidified and formed, the two movable molds move away from each other, so that the wine bottle is separated from the molding cavity.

[0004] When demolding, the wine bottle usually leaves two molding cavities at the same time. When it is about to be completely separated, if the worker does not grab the wine bottle in time, the bottom of the wine bottle will collide with the base on which the mold is placed, or even fall over and break, so there is an obvious deficiency. Utility Model Content

[0005] In order to improve the problem that glass products may be damaged when two movable molds are separated, the present application provides a lifting mechanism for removing glass products.

[0006] The present application provides a lifting mechanism for removing glass products using the following technical solution:

[0007] A lifting mechanism for removing glass products comprises two supporting rods hinged in a base, the two supporting rods are symmetrically arranged about the close contact surface of two movable molds after being assembled, one end of the supporting rod extends to the bottom of the glass product and is provided with a lifting block, and the other end extends to the upper surface of the base. When the two movable molds are assembled, the supporting rod is inclined upward in a direction away from the molding cavity.

[0008] By adopting the above technical solution, when the molds are separated, the two movable molds move away from each other, the movable mold contacts the rod body of the support rod protruding from the upper surface of the base and pushes it to rotate, and the support rod drives the lifting block to rotate to the bottom of the supporting glass product. Even if the glass product is completely separated from the molding cavity, the glass product can stay stably on the lifting block, thereby reducing the possibility of glass products being damaged due to impact or tipping during the stripping process.

[0009] Optionally, an air pump electrically connected to the control system is also arranged in the base, and air holes are passed through the lifting block and the supporting rod. One end of the air hole is connected to the bottom of the glass product, and the other end is connected to the air outlet of the air pump through a hose. The supporting rod is also provided with a side air inlet hole that connects the air hole to the outside world.

[0010] By adopting the above technical solution, the vacuum pump draws out the air in the vacuum hole through the hose. When the air intake volume per unit time of the side air inlet hole is small and the vacuum pump draws a large amount of air for a long time, negative pressure will be formed in the vacuum hole, thereby generating adsorption force on the glass products on the lifting block, reducing the possibility of the glass products being unstable and tipping over during the demoulding process.

[0011] Optionally, a regulating valve electrically connected to a control system is provided at the position of the air inlet hole on the opposite side of the support rod.

[0012] By adopting the above technical solution, workers adjust the opening and closing size of the regulating valve through the control system, thereby regulating the air intake rate, thereby adjusting the size of the negative pressure adsorption force on the glass products.

[0013] Optionally, the lifting block is detachably connected to the supporting rod.

[0014] By adopting the above technical solution, when used for lifting glass products of different types and models, workers can replace suitable lifting blocks, thereby improving the lifting effect of the glass products.

[0015] Optionally, an elastic rubber pad is arranged on the side wall of the lifting block for lifting the bottom of the glass product, and the air extraction hole is pressed onto the elastic rubber pad.

[0016] By adopting the above technical solution, the elastic rubber pad plays a protective role on the supporting part of the bottom of the glass product.

[0017] Optionally, a plurality of plug-in slots are spaced apart on the base in a direction away from the molding cavity, and the plug-in slots are plugged with plug-in blocks, a rotating shaft is arranged on the plug-in block, and the support rod is rotatably sleeved on the rotating shaft.

[0018] By adopting the above technical solution, workers insert the plug-in blocks into different plug-in slots to adjust the position of the rotation center of the support rod, and then adjust the lifting timing of different glass products.

[0019] Optionally, a magnetic block for magnetic attraction with the base is arranged on the plug-in block.

[0020] By adopting the above technical solution, the magnetic block and the base are magnetically attracted to each other, thereby reducing the possibility of the plug-in block accidentally detaching from the plug-in slot.

[0021] Optionally, an inclined platform is circumferentially provided at the edge of the bottom of the plug-in block, and the diameter of the inclined platform gradually decreases from top to bottom.

[0022] By adopting the above technical solution, the arrangement of the inclined platform facilitates the insertion of the plug-in block into the plug-in slot.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When the mold is separated, the two movable molds move away from each other, and the movable mold contacts the rod body of the support rod protruding from the upper surface of the base and pushes it to rotate. The support rod drives the lifting block to rotate to the bottom of the supporting glass product. Even if the glass product is completely out of the molding cavity, the glass product can stay steadily on the lifting block, thereby reducing the possibility of glass products being damaged due to impact or tipping during the stripping process;

[0025] 2. The vacuum pump draws out the air in the vacuum hole through the hose. When the air intake volume per unit time of the side air inlet is small and the vacuum pump draws a large amount of air, negative pressure will be formed in the vacuum hole, thereby generating adsorption force on the glass products on the lifting block, reducing the possibility of the glass products being unstable and falling during demoulding;

[0026] 3. Workers insert the plug-in blocks into different plug-in slots to adjust the position of the rotation center of the support rod, and then adjust the lifting timing of different glass products. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following is combined with Figure 1-2 This application is described in further detail.

[0031] The embodiment of the present application discloses a lifting mechanism for removing glass products.

[0032] Reference Figure 1 The lifting mechanism for removing the glass product includes two supporting rods 3 hinged in the base 1, and the two supporting rods 3 are symmetrically arranged about the close contact surface of the two movable molds 2 after being assembled. One end of the supporting rod 3 extends to the bottom of the glass product and is bolted with a lifting block 4, and the other end extends to the upper surface of the base 1.

[0033] Reference Figure 1 Two movable molds 2 are slidably arranged on a base 1 and powered by a driving member, which directly adopts existing technology, such as a cylinder, a hydraulic cylinder, etc.

[0034] Reference Figure 1When the two movable molds 2 are in the mold closing state, the supporting rod 3 tilts upward in the direction away from the molding cavity 201. When the two movable molds 2 move away from each other to realize mold separation, the movable mold 2 contacts the rod body of the corresponding supporting rod 3 protruding from the upper surface of the base 1 and drives it to rotate.

[0035] The supporting rod 3 drives the corresponding supporting block 4 to rotate, so that the supporting block 4 gradually approaches the bottom of the glass product. When the glass product is completely out of the molding cavity 201, the bottom of the glass product is just placed on the supporting block 4.

[0036] In the above manner, the glass products can be supported and lifted during the demoulding process, reducing the possibility of glass products being damaged due to impact or tipping, and making it easier for workers to retrieve the materials later.

[0037] Reference Figure 1 The lifting block 4 is used to lift the bottom of the glass product and has an elastic rubber pad (not shown in the figure) bonded to its side wall. The elastic rubber pad protects the lifting part of the glass product and reduces the possibility of damage to the glass product.

[0038] Reference Figure 1 An air pump (not shown in the figure) electrically connected to the control system is also arranged in the base 1, and an air hole 301 is passed through the lifting block 4 and the supporting rod 3. One end of the air hole 301 extends to the elastic rubber pad and is connected to the bottom of the glass product, and the other end is connected to the air outlet end of the air pump through the hose 11.

[0039] Reference Figure 1 The support rod 3 is also provided with a side air inlet hole (not shown in the figure) for connecting the air extraction hole 301 with the outside world, and a regulating valve 5 electrically connected to the control system is threadedly connected at the position of the support rod 3 opposite to the side air inlet hole.

[0040] Reference Figure 1 During the mold separation process, the control system starts the vacuum pump, and the vacuum pump extracts the air in the vacuum hole 301 through the hose 11. Since the vacuum pump has a large vacuum rate and the air intake rate of the control valve is small, a negative pressure is formed in the vacuum hole 301, thereby causing the vacuum hole 301 to generate a negative pressure adsorption force on the glass product.

[0041] The negative pressure can firmly adsorb the glass product on the lifting block 4, thereby reducing the possibility of the glass product falling due to unstable force during the mold separation process.

[0042] The worker adjusts the opening size of the regulating valve 5 through the control system, so that the air intake rate of the regulating valve 5 changes accordingly, and then the size of the adsorption force on the glass products can be adjusted, further improving the applicability of the present application.

[0043] Reference Figure 1 and Figure 2A plurality of plug-in slots 101 are provided on the base 1 at intervals along a direction away from the molding cavity 201 . The plug-in slots 101 are plugged with plug-in blocks 7 . The plug-in blocks 7 are threadedly connected with a rotating shaft 8 . The support rod 3 is rotatably sleeved on the rotating shaft 8 .

[0044] The worker plugs the plug-in block 7 into different plug-in slots 101 to match them, thereby adjusting the position of the rotation center of the support rod 3, and further adjusting the lifting timing of the lifting block 4 for different glass products.

[0045] Reference Figure 1 and Figure 2 A ramp 10 is circumferentially provided at the edge of the bottom of the plug-in block 7, and the diameter of the ramp 10 gradually decreases from top to bottom. A magnetic block 9 for magnetically attracting the base 1 is embedded at the bottom of the plug-in block 7. The magnetic block 9 is magnetically attracted to the base 1, thereby reducing the possibility of the plug-in block 7 accidentally detaching from the plug-in slot 101.

[0046] The implementation principle of a lifting mechanism for removing glass products in the embodiment of the present application is as follows:

[0047] When the two movable molds 2 move away from each other to realize mold separation, the movable mold 2 contacts the rod body of the corresponding supporting rod 3 protruding from the upper surface of the base 1 and drives it to rotate. The supporting rod 3 drives the corresponding lifting block 4 to rotate, so that the lifting block 4 gradually approaches the bottom of the glass product. When the glass product completely leaves the molding cavity 201, the bottom of the glass product is just placed on the lifting block 4.

[0048] During the demolding process, the control system starts the vacuum pump, which extracts the air in the vacuum hole 301 through the hose 11. Since the vacuum pump has a high vacuum rate and the air intake rate of the control valve is low, negative pressure is formed in the vacuum hole 301, which causes the vacuum hole 301 to generate negative pressure adsorption force on the glass product, thereby reducing the possibility of the glass product tipping over.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
