Description

Technical Field

[0001] This utility model belongs to the field of washing machine glass production equipment, specifically relating to a connecting structure for a concave mold bending handle in washing machine glass production. Background Technology

[0002] In the production of glass observation windows, the melting and forming of glass need to be carried out in a high-temperature environment, with temperatures near the furnace reaching thousands of degrees Celsius. The instantaneous temperature of the mold when in contact with the molten material exceeds 1,000 degrees Celsius, the average working temperature of the mold is around 500 degrees Celsius, and the average weight of the mold is around 100 kilograms.

[0003] The production process requires four M12*20MM (12.9) screws connected to a T-shaped handle to place the die on the press jaws for four-position rotary pressing. The die needs to be preheated to 600-800℃ before use, exceeding the annealing temperature of the 12.9 grade screws, causing a sharp decrease in their tensile strength. Furthermore, during production, the screws connecting the T-shaped handle and the die can loosen or even break due to the die's lifting and vibration. If any one screw breaks, it can cause the die to collide with the press turntable, leading to a shutdown and production stoppage. In severe cases, it can damage both the press and the die, resulting in prolonged downtime for repairs or even die failure.

[0004] If you choose ultra-high temperature resistant screws, they will not have enough tensile strength, will be easy to loosen, have a short lifespan, and be expensive and not cost-effective. Utility Model Content

[0005] In order to solve the problems existing in the prior art, this utility model provides a connecting structure for the concave mold of washing machine glass production, which can reduce the stress on the first screw and effectively reduce its breakage risk. Even if the first screw breaks, it can still effectively avoid collision between the concave mold and the press turntable, and long-term downtime caused by damage to the mold and the press.

[0006] The specific technical solution adopted in this utility model is as follows:

[0007] A connecting structure for a curved handle of a glass production die for a washing machine includes a connecting plate and a horizontal shaft. The connecting plate is vertical and connected to an ear plate by means of a first screw. The horizontal shaft is connected to a press claw. The key feature is that a support plate extends from the lower end of the connecting plate. The support plate is located below the ear plate and is fixedly connected to the ear plate. The support plate supports the ear plate.

[0008] The tray is connected to the ear plate by means of a second screw. The axis of the first screw is parallel to the axis of the horizontal axis, and the axis of the second screw is perpendicular to the axis of the horizontal axis.

[0009] The connecting plate is provided with screw through holes and first heat dissipation holes. The screw through holes are countersunk holes on one side of the lead screw of the first screw. The screw through holes and the lead screw of the first screw form an annular heat dissipation seam. The first heat dissipation holes are parallel to and spaced apart from the screw through holes. The first heat dissipation holes and the heat dissipation seam are connected.

[0010] The heat dissipation seam is also provided with a limiting sleeve that surrounds the lead screw of the first screw.

[0011] The head of the first screw is higher than the surface of the connecting plate.

[0012] The connecting plate is provided with a second heat dissipation hole, the axis of which is perpendicular to the axis of the first heat dissipation hole, and the inner end of the second heat dissipation hole is connected to the heat dissipation seam.

[0013] Shock-absorbing and heat-insulating pads are respectively provided between the connecting plate and the ear plate, and between the support plate and the ear plate.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model adopts the addition of a support plate on the connecting plate. The support plate lifts the ear plate upward, increasing the support area of ​​the ear plate. In the event of the first screw breaking, it can also prevent the die from falling and causing damage to the die and press. The machine can be restarted by replacing the first screw, shortening the maintenance time and avoiding the serious impact of long-term downtime on production efficiency.

[0016] 2. The support plate is connected to the ear plate by a vertically set second screw. The first screw and the second screw fix the ear plate from different directions, so that the force on the first screw and the second screw is more balanced, the connection temperature is reduced, the first screw and the second screw are delayed from loosening, and the screw is reduced from breaking due to excessive local stress.

[0017] 3. The heat dissipation seam, first heat dissipation hole and second heat dissipation hole added to the connecting plate form an air circulation path, so that the heat around the first screw can be dissipated in time, avoiding the accumulation of heat at the first screw, which helps to prevent the first screw from reaching the annealing temperature.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0027] Specific implementation examples Figure 1-6 As shown, this utility model relates to a connecting structure for a curved handle of a glass production die for a washing machine. It includes a connecting plate 1 and a horizontal shaft 2. The connecting plate 1 is vertical and connected to an ear plate 4 via a first screw 6, and is connected to the ear plate 4 of the die 3. The horizontal shaft 2 is connected to the press claw. Crucially, a support plate 5 extends from the lower end of the connecting plate 1. The support plate 5 is located below the ear plate 4 and fixedly connected to it, providing support for the ear plate 4. The vertical force on the die 3 is changed from being borne solely by the first screw 6 to being shared by the first screw 6 and the support plate 5, thereby reducing the stress on the first screw 6 and effectively lowering its breakage risk. Furthermore, even if the first screw 6 breaks, the support plate 5 can still support the ear plate 4, effectively preventing the die 3 from colliding with the press turntable due to the breakage of the first screw 6, and avoiding prolonged downtime caused by damage to the die and press.

[0028] On the other hand, the support plate 5 is connected to the ear plate 4 by means of the second screw 7. The axis of the first screw 6 is set parallel to the axis of the horizontal axis 2, and the axis of the second screw 7 is set perpendicular to the axis of the horizontal axis 2. The first screw 6 and the second screw 7 fix the ear plate 4 in different directions, so that the force on the first screw 6 and the second screw 7 is more balanced, reducing the risk of the first screw 6 breaking due to excessive local force.

[0029] The placement of the support plate 5 and the second screw 7 improves the integrity and connection stability of the ear plate 4 and the connecting structure. The first screw 6 and the second screw 7 restrict the relative displacement between the ear plate 4 and the connecting plate 1, reducing the relative displacement between the ear plate 4 and the connecting plate 1 during operation. This helps to maintain the tightness of the first screw 6 and the second screw 7 on the ear plate 4, slowing down the loosening of the ear plate 4 caused by the screws 6 and the second screw 7. It also prevents the ear plate 4 from breaking due to uneven stress after the first screw 6 and the second screw 7 loosen. Furthermore, it helps to reduce the frequency of maintenance and downtime, and contributes to improving production efficiency.

[0030] like Figure 1 , Figure 4 As shown, the connecting plate 1 is provided with a screw through hole 8 and a first heat dissipation hole 9. The screw through hole 8 is a countersunk hole structure on the lead screw side of the first screw 6, that is, the large diameter hole of the screw through hole 8 is located close to the ear plate 4. The screw through hole 8 and the lead screw of the first screw 6 form an annular heat dissipation seam 12. The first heat dissipation hole 9 is parallel to the screw through hole 8 and spaced apart, and the first heat dissipation hole 9 is connected to the heat dissipation seam 12. The setting of the heat dissipation seam 12 and the first heat dissipation hole 9 not only reduces the contact area between the connecting plate 1 and the ear plate 4, but also forms an air circulation path, so that the heat around the first screw 6 can be dissipated in time, avoiding the accumulation of heat at the first screw 6, effectively reducing the ambient temperature around the first screw 6, and helping to prevent the first screw 6 from reaching the annealing temperature.

[0031] A limiting sleeve 13 is also provided inside the heat dissipation gap 12, surrounding the lead screw of the first screw 6. The limiting sleeve 13 is made of heat-insulating material, such as ceramic fiber. The outer diameter of the limiting sleeve 13 is smaller than the diameter of the large diameter hole of the screw through hole 8. The first heat dissipation hole 9 is located between the large diameter hole of the screw through hole 8 and the limiting sleeve 13, and communicates with the heat dissipation gap 12. The limiting sleeve 13 supports the lead screw of the first screw 6 and blocks the heat of the die 3, reducing the heat transferred from the die 3 to the connecting plate 1.

[0032] The head of the first screw 6 is higher than the surface of the connecting plate 1, which increases the contact area between the first screw 6 and the outside air, helps to dissipate the heat on the first screw 6, and further reduces the risk of the first screw 6 reaching the annealing temperature.

[0033] like Figure 5 As shown, second heat dissipation holes 10 are provided on the side walls of the left and right sides of the connecting plate 1. The axial direction of the second heat dissipation holes 10 is perpendicular to the axial direction of the first heat dissipation holes 9. The inner end of the second heat dissipation holes 10 is connected to the heat dissipation seam 12. Specifically, the axial direction of the first heat dissipation holes 9 is horizontal, and the axial direction of the second heat dissipation holes 10 is vertical. The setting of the second heat dissipation holes 10 further accelerates the circulation of hot air in the heat dissipation seam 12 with the outside air, and improves the heat dissipation speed around the first screw 6.

[0034] like Figure 7 As shown, shock-absorbing and heat-insulating pads 11 are respectively provided between the connecting plate 1 and the ear plate 4, and between the support plate 5 and the ear plate 4. The shock-absorbing and heat-insulating pads 11 are respectively provided with holes for the first screw 6 and the second screw 7 to pass through. Preferably, the material of the shock-absorbing and heat-insulating pads 11 is ceramic fiber. The shock-absorbing and heat-insulating pads 11 can not only buffer the vibration generated during the operation of the press and reduce the impact force borne by the first screw 6 and the second screw 7, but also insulate the connection plate 1 and the ear plate 4, and the support plate 5 and the ear plate 4, reducing the heat transferred from the die 3 to the connection plate 1 and the support plate 5, thereby cooling the area around the first screw 6 and the second screw 7 on the connection plate 1 and the support plate 5, which helps to prevent the first screw 6 and the second screw 7 from annealing.
