Abstract
Description
Technical Field
[0001] This utility model relates to the field of production equipment technology, and in particular to a door opening and closing structure for a bathtub forming equipment and the bathtub forming equipment itself. Background Technology
[0002] Existing bathtub molding equipment sometimes uses acrylic heating and softening to form the bathtub. During production, acrylic sheets are placed on a worktable and softened by a heating device. The worktable has an opening, and a mold is placed below the opening. After the sheet softens, air is blown into it through the opening, causing it to bulge. The mold is then moved to the opening on the worktable, and vacuum suction is used to press the sheet against the mold. After cooling and solidification, the bathtub blank is demolded and removed. It then undergoes cutting and polishing to obtain the finished product. For this type of bathtub molding equipment, the worktable is typically a box-shaped structure. To facilitate mold replacement within the cavity, an auxiliary opening is provided on the side of the worktable box, and a movable or rotating door is connected to this opening. The door is usually locked to the worktable box by a lock on the free end of the door. This structure is relatively simple but has poor reliability. When air is blown or vacuum suction is applied to the worktable cavity, gaps easily appear around the door, leading to air leakage and affecting the bathtub molding process. Utility Model Content

[0033] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 A door opening and closing structure for a bathtub molding device includes a worktable 100 and a door 200. The worktable 100 has a box-like structure and an auxiliary opening 101 on its side. The door 200 is connected to the worktable 100 and is positioned corresponding to the auxiliary opening 101. The door 200 can rotate relative to the worktable 100 to cover or open the auxiliary opening 101. The back of the door 200 is provided with a driver 210 and a locking member 220. Multiple locking members 220 are movably connected to the door 200 and are respectively positioned on both sides of the door 200 along the height direction and / or on both sides along the width direction. The driver 210 is kinetically connected to the locking member 220 and can drive the locking member 220 to move. When the door 200 is in the state of covering the auxiliary opening 101, the locking member 220 can move relative to the edge of the door 200 so that the edge wall of the auxiliary opening 101 is clamped and fixed between the edge portion of the door 200 and the locking member 220.
[0034] Understandably, such as Figure 1 , Figure 2 and Figure 4 As shown, Figure 1 The bathtub molding equipment has two worktables 100, one on the left and one on the right. An auxiliary opening 101 is located on the left side of the right worktable 100, and a door 200 is correspondingly located on the left side of this worktable 100. Figure 2 and Figure 4Taking the door 200 as an example, its back side is the right side shown in the figure, that is, the side facing the inner cavity of the workbench 100 when the door 200 is in the closed state. The back side of the door 200 is equipped with a driver 210 and multiple locking elements 220. In use, the door 200 is moved relative to the workbench 100 to either cover or open the auxiliary opening 101 of the workbench 100, thus closing and opening the door 200. By providing multiple movable locking elements 220 on the back side of the door 200, when the door 200 is in the state of covering the auxiliary opening 101, refer to... Figure 4 and Figure 5 The driver 210 drives the locking member 220 to move relative to the edge of the door body 200, so that the edge wall of the auxiliary opening 101 is clamped and fixed between the edge part of the door body 200 and the locking member 220, thereby achieving a more stable and reliable locking effect, reducing the possibility of air leakage caused by gaps around the door body 200, and making it easier to use.
[0035] In practical applications, the specific structure of the locking element 220 and the specific connection structure between the workbench 100 and the door 200 can be set according to the actual needs of use. They will not be described in detail here, but will be explained in detail below.
[0036] In some embodiments, a connecting component 300 is provided between the door body 200 and the workbench 100 and is connected by the connecting component 300. The door body 200 can rotate relative to the workbench 100 and move in a direction perpendicular to the auxiliary opening 101 through the connecting component 300.
[0037] Understandably, such as Figure 2 and Figure 3 As shown, the connecting component 300 is located on the front side of the door 200. The door 200 is connected to the workbench 100 via the connecting component 300. When switching from the open state to the closed state, the door 200 can first rotate relative to the workbench 100 to the left side parallel to the workbench 100 via the connecting component 300, and then move towards the auxiliary opening 101 in a direction perpendicular to the auxiliary opening 101, so that the door 200 moves to press against the left side of the workbench 100, thereby closing the door 200. The rotation and movement design of the door 200 allows it to fit well against the side of the workbench 100, further reducing the possibility of air leakage due to gaps around the door 200 and facilitating use. In practical applications, the specific structure of the connecting component 300 can be set according to actual usage needs, and will not be described in detail here, but will be explained in detail below.
[0038] In some embodiments, the connecting assembly 300 includes a first connector 310, a second connector 320, and a connecting seat 330. The connecting seat 330 is fixedly disposed on the workbench 100. The first connector 310 is fixedly connected to the door body 200. The second connector 320 is movably connected to the connecting seat 330 and can move in the direction of moving closer to or away from the auxiliary opening 101. The first connector 310 and the second connector 320 are hinged together.
[0039] Understandably, such as Figure 2 and Figure 3 As shown, the connecting seat 330 is fixedly mounted on the workbench 100. The first connecting member 310 is fixedly connected to the door body 200, and the second connecting member 320 is movably connected to the connecting seat 330 and can move in the left and right directions to move closer to or further away from the auxiliary opening 101. The first connecting member 310 and the second connecting member 320 are hinged together, thereby enabling relative rotation and movement between the door body 200 and the workbench 100. The structure is simple and easy to use. In practical applications, in addition to the above structure, the first connecting member 310 and the second connecting member 320 can be made relatively movable, and the second connecting member 320 and the connecting seat 330 can be made relatively rotatable. Alternatively, a linkage mechanism can be used to connect the door body 200 and the workbench 100, allowing them to move and rotate. The specific configuration can be changed according to actual usage needs.
[0040] In some embodiments, a limiting structure (not shown in the figure) is provided between the second connector 320 and the connector 330, the limiting structure being used to limit the travel of the second connector 320 relative to the connector 330.
[0041] Understandably, by setting a limiting structure to restrict the travel of the second connector 320 relative to the connecting seat 330, the second connector 320 can be prevented from moving away from the connecting seat 330, ensuring the reliability of the connection structure. In practical applications, the limiting structure can be a stop block set on the movement path of the second connector 320 to block the movement of the second connector 320, thereby achieving the effect of limiting its travel. Alternatively, the limiting structure can be a long, narrow limiting groove, with part of the second connector 320 set in the limiting groove, using the limiting groove to limit the travel of the second connector 320. The specific structural form of the limiting structure can be set according to the actual usage requirements.
[0042] In some embodiments, the rotation axis of the door body 200 relative to the workbench 100 is parallel to the height direction of the door body 200, and a plurality of locking members 220 are respectively disposed on both sides of the door body 200 along the height direction to form two rows of locking groups, and the plurality of locking members 220 in each row of locking groups are distributed at intervals along the width direction of the door body 200.
[0043] Understandably, such as Figure 2 and Figure 4 As shown, the height of the door 200 is parallel to the vertical direction, the width of the door 200 is parallel to the front-back direction, and the rotation axis of the door 200 relative to the worktable 100 is parallel to the vertical direction. Eight locking elements 220 are provided and respectively located on the upper and lower sides of the door 200, forming two rows of locking groups. Each row of locking groups contains four locking elements 220, which are spaced apart along the front-back direction. This locks the door 200 when it is closed. The structure is simple, the locking effect is stable and reliable, and it is easy to use. In practical applications, in addition to the above arrangement, multiple locking elements 220 can be respectively located on both sides of the door 200 along the width direction to form two rows of locking groups. Alternatively, corresponding locking elements 220 can be provided on all sides of the door 200. The number of locking elements 220 can be four, six, or more, depending on the actual needs of use.
[0044] In some embodiments, the driving end of the driver 210 is connected to a moving member 230 and can drive the moving member 230 to move horizontally. The upper and lower sides of the moving member 230 are provided with connecting rods 240. Multiple connecting rods 240 are provided corresponding to the locking member 220. The two ends of each connecting rod 240 are rotatably connected to the moving member 230 and the locking member 220 respectively. The moving member 230 can drive the locking member 220 to move up and down through the connecting rods 240.
[0045] Understandably, such as Figure 4 As shown, there are two actuators 210. Each actuator 210 has a moving member 230 connected to its driving end. The upper and lower sides of the moving member 230 are rotatably connected to one end of a connecting rod 240. The other end of the connecting rod 240 is rotatably connected to a locking member 220, thus forming a double-slider mechanism. The actuator 210 drives the moving member 230 to move horizontally, and the connecting rod 240 drives the locking member 220 to move vertically, thereby achieving the movement of the upper and lower locking members 220. The structure is simple, which helps reduce the number of actuators 210 and lowers production costs. In practical applications, in addition to the above structure, multiple actuators 210 can be set, each actuator 210 driving the corresponding locking member 220 to move, thus achieving the movement of multiple locking members 220. The specific configuration can be adjusted according to actual usage needs.
[0046] In some embodiments, a guide sleeve 250 is provided on the back side of the door body 200, and multiple guide sleeves 250 are provided corresponding to locking members 220, with the locking members 220 movably passing through the corresponding guide sleeves 250.
[0047] Understandably, such as Figure 4 and Figure 5As shown, the guide sleeve 250 has multiple corresponding locking elements 220. By movably inserting the locking element 220 into the corresponding guide sleeve 250, a movable connection between the locking element 220 and the door body 200 is achieved, and the movement direction of the locking element 220 can be effectively restricted. Its structure is simple and easy to use. In practical applications, in addition to the above structure, the locking element 220 can also be connected to the back side of the door body 200 through a slide rail slider structure, which can be set according to actual usage needs.
[0048] In some embodiments, the end of the locking member 220 is provided with a pressing slope 221. When the locking member 220 moves toward the edge wall of the auxiliary opening 101, the locking member 220 can push against the edge wall of the auxiliary opening 101 through the pressing slope 221 and cooperate with the door body 200.
[0049] Understandably, such as Figure 4 and Figure 5 As shown, the locking member 220 has a pressing bevel 221 at its end. When the locking member 220 moves closer to the edge wall of the auxiliary opening 101, the pressing bevel 221 abuts against the edge wall of the auxiliary opening 101. As the locking member 220 continues to move, it can push against the edge wall of the auxiliary opening 101 through the pressing bevel 221 to cooperate with the door body 200, so that the locking member 220 and the door body 200 achieve a relatively stable and reliable clamping effect on the edge wall of the auxiliary opening 101, further reducing the possibility of air leakage caused by gaps around the door body 200. In practical applications, the pressing bevel 221 can be set according to actual usage needs.
[0050] In some embodiments, a sealing ring 110 is provided at the edge of the auxiliary opening 101. When the door body 200 is in the state of covering the auxiliary opening 101, the door body 200 abuts against the sealing ring 110. Alternatively, a sealing ring 110 is provided on the back edge of the door body 200. When the door body 200 is in the state of covering the auxiliary opening 101, the edge wall of the auxiliary opening 101 abuts against the sealing ring 110.
[0051] Understandably, such as Figure 2 , Figure 3 and Figure 5 As shown, a sealing ring 110 is provided on the back edge of the door body 200. When the door body 200 is in the state of covering the auxiliary opening 101, the door body 200 abuts against the edge wall of the auxiliary opening 101 through the sealing ring 110, thereby improving the sealing performance between the door body 200 and the edge wall of the auxiliary opening 101, and further reducing the possibility of air leakage due to gaps around the door body 200. In practical applications, the sealing ring 110 can also be set at the edge of the auxiliary opening 101, which can be changed according to actual usage needs.
[0052] According to a second aspect embodiment of the present invention, a bathtub molding apparatus, such as Figure 1 As shown, it includes a door opening and closing structure for a bathtub molding apparatus according to the first aspect embodiment of the present invention.
[0053] According to the bathtub molding equipment of this utility model embodiment, by adopting the opening and closing door structure of the bathtub molding equipment described above, the edge wall of the auxiliary opening 101 can be clamped and fixed between the edge part of the door 200 and the locking member 220 when the door 200 is in the closed state, thereby achieving a more stable and reliable locking effect, reducing the possibility of air leakage caused by gaps around the door 200, and facilitating use.
[0054] Since other components of the bathtub molding equipment of this utility model embodiment are known to those skilled in the art, they will not be described in detail here.
[0055] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings.
