Description

Technical Field

[0001] The invention relates to the field of plastic blister moulds, in particular to an automatic connection and locking device for a vacuum water channel of a plastic blister mould. Background Art

[0002] Blister molds are widely used in the manufacture of plastic packaging, daily necessities, product shells and other fields. They can be used to produce various plastic products such as shells, trays, blister boxes, etc.

[0003] Compared with other types of molds such as injection molds, the cost of blister molds is relatively low, especially for some large and complex-shaped plastic products, blister molds can significantly reduce the investment cost of molds. In addition, blister molds have a short cycle for manufacturing plastic products and can be completed quickly, meeting the company's demand for a short product development cycle.

[0004] However, in general, the parts of blister molds are relatively large. Due to their short production cycle, mold changes are relatively frequent, and the water channels, vacuum, and temperature controllers on the molds need to be manually connected, which will lead to high labor intensity for employees, low mold change efficiency, and time-consuming and labor-intensive. Summary of the invention

[0005] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and to provide an automatic connection and locking device for the vacuum water channel of a blister mold.

[0006] According to one aspect of the present invention, there is provided an automatic connection and locking device for a vacuum waterway of a blister mold, comprising a mold fixing plate for carrying the blister mold, a water inlet and a vacuum connection port being provided on the mold fixing plate, and further comprising:

[0007] A bearing plate, on which a plug adapted to the water inlet and a vacuum connection plug adapted to the vacuum connection port are provided;

[0008] A positioning column for abutting the mold fixing plate, the positioning column is inserted in the bearing plate and can move up and down in the bearing plate, and a positioning hole adapted to the positioning column is provided on the mold fixing plate;

[0009] A first driving device, the first driving device drives the positioning column to move up and down;

[0010] A locking piece, wherein the mold fixing plate is provided with a locking hole, and the locking piece is inserted into the locking hole; and

[0011] The second driving device drives the locking member to rotate so as to be locked on the periphery of the end of the lock hole.

[0012] The automatic connection and locking device of the vacuum waterway of the blister mold of the present invention, when changing the mold, firstly, the first driving device drives the positioning column to move upward so that the positioning column is ejected from the bearing plate, and the mold fixing plate carrying the blister mold is placed on the positioning column by a forklift and the top of the positioning column is inserted into the positioning hole on the mold fixing plate, and then the first driving device drives the positioning column to move downward, and the mold fixing plate carrying the blister mold descends, under the guiding action of the positioning column, the plug on the bearing plate is inserted into the water inlet of the mold fixing plate, and the vacuum connection plug on the bearing plate is inserted into the vacuum connection port on the mold fixing plate, and at the same time, the locking member is inserted into the lock hole, and then under the driving action of the second driving device, the locking member rotates and buckles on the periphery of the end of the lock hole, and the locking member locks the mold fixing plate carrying the blister mold, and the automatic connection and installation of the vacuum and waterway of the blister mold are completed at this time, so that the blister mold can be realized in the process of changing the mold, and the vacuum and waterway of the blister mold can be quickly and automatically installed in place in one step, which effectively improves the production efficiency of mold changing and mold installation, reduces the labor intensity of employees, and realizes rapid mold change.

[0013] Furthermore, the second driving device includes a cylinder, a transmission rod and a positioning ring. The cylinder and the positioning ring are both arranged at the bottom of the supporting plate. The locking piece is inserted into the positioning ring and can rotate in the positioning ring. One end of the transmission rod is hinged to the first end of the cylinder, and the other end of the transmission rod is fixed to the first end of the locking piece. The second end of the locking piece can extend from the lock hole. The cylinder can drive the locking piece to rotate so that the second end of the locking piece is buckled on the periphery of the end of the lock hole.

[0014] Therefore, when the second end of the locking piece extends from the locking hole and the mold fixing plate needs to be locked, the piston rod (the first end of the second driving device) of the cylinder (the second driving device) extends or retracts, and the transmission rod can drive the locking piece to rotate so that the second end of the locking piece is buckled on the periphery of the end of the locking hole. At this time, the locking piece completes the operation of locking the mold fixing plate. When the mold needs to be changed, the piston rod (the first end of the second driving device) of the cylinder (the second driving device) retracts or extends, and the transmission rod drives the locking piece to rotate in the opposite direction, and the second end of the locking piece is separated from the periphery of the end of the locking hole. At this time, the locking piece completes the unlocking operation, and the positioning ring can ensure that the locking piece rotates smoothly on the supporting plate and in the locking hole to achieve locking and unlocking actions.

[0015] Furthermore, the number of the locking holes, the locking fasteners and the second driving device are all four, the four locking holes are distributed at the four corners of the mold fixing plate, and the four locking fasteners can be inserted into the four locking holes respectively.

[0016] A cylinder can drive a lock member to rotate so that the second end of the lock member is buckled on the periphery of an end of a lock hole.

[0017] Therefore, the four locking parts can lock the mold fixing plate and the carrier plate together in a balanced and stable manner, ensuring that the plug on the carrier plate is accurately inserted into the water outlet on the mold fixing plate, and the vacuum connection plug on the carrier plate is accurately inserted into the vacuum connection port on the mold fixing plate.

[0018] Furthermore, it also includes two connecting rods, wherein:

[0019] One end of a connecting rod is arranged on the first end of the first cylinder, and the other end of the connecting rod is arranged on the first end of the second cylinder.

[0020] One end of another connecting rod is arranged on the first end of the third cylinder, and the other end of the connecting rod is arranged on the first end of the fourth cylinder.

[0021] Therefore, one connecting rod can connect two cylinders together. When locking action is required, the cylinder at one end of the connecting rod extends, and at the same time, the cylinder at the other end of the connecting rod retracts. The two cylinders can drive the two lock fasteners to rotate synchronously to achieve locking operation, ensuring that the two lock fasteners are locked synchronously and smoothly. When unlocking action is required, the cylinder at one end of the connecting rod retracts, and at the same time, the cylinder at the other end of the connecting rod extends. The two cylinders can drive the two lock fasteners to rotate synchronously in opposite directions to achieve unlocking operation, ensuring that the two lock fasteners are unlocked synchronously and smoothly. A connecting rod can connect the other two cylinders together. When locking action is required, the cylinder at one end of the connecting rod extends, and at the same time, the cylinder at the other end of the connecting rod retracts. The two cylinders can drive the other two locking parts to rotate synchronously to achieve locking operation, ensuring that the two locking parts are locked synchronously and smoothly. When unlocking action is required, the cylinder at one end of the connecting rod retracts, and at the same time, the cylinder at the other end of the connecting rod extends. The two cylinders can drive the two locking parts to rotate synchronously in opposite directions to achieve unlocking operation, ensuring that the two locking parts are unlocked synchronously and smoothly.

[0022] Furthermore, the lock hole is in an oblong shape, and a convex edge is provided on the second end of the locking member, and the length of the convex edge is greater than the width of the lock hole.

[0023] Therefore, when locking action is required, under the driving action of the second driving device, the locking member rotates a certain angle (such as 90 degrees) so that the length of the protruding edge is perpendicular to the length direction of the locking hole, ensuring that the protruding edge can be firmly buckled on the periphery of the end of the locking hole.

[0024] Furthermore, inclined portions are respectively provided on opposite sides of the end surface of the protruding edge close to the bearing plate.

[0025] Therefore, during the mold changing process, when the positioning column drops to the lowest position, through parameter and size design, the edge of the top opening of the lock hole is just flush with the highest point of the inclined portion. At this time, when the lock piece rotates, the inclined portion on the convex edge will gradually press down the periphery of the end of the lock hole, that is, gradually press down the mold fixing plate. When the lock piece rotates a certain angle (such as 90 degrees), the convex edge on the lock piece can firmly lock the mold fixing plate and the carrier plate together.

[0026] Further, the water inlet includes a water inlet and a water outlet, the plug includes a water inlet plug adapted to the water inlet and a water outlet plug adapted to the water outlet, the inner walls of the water inlet and the water outlet are both provided with a first sealing ring, and the inner wall of the vacuum connection port is provided with a second sealing ring.

[0027] A thermostat connector is arranged on the mold fixing plate, and a thermostat plug adapted to the thermostat connector is arranged on the bearing plate.

[0028] Therefore, when the locking piece locks the mold fixing plate and the loading plate together, the water inlet plug on the loading plate is inserted into the water inlet on the mold fixing plate, the water outlet plug on the loading plate is inserted into the water outlet on the mold fixing plate, the vacuum connection plug on the loading plate is inserted into the vacuum connection port on the mold fixing plate, and the thermostat plug on the loading plate is plugged together with the thermostat connector on the mold fixing plate. Cooling water can enter the blister mold through the water inlet plug and the water inlet to cool the product. The cooled water can be discharged through the water outlet and the water outlet plug. The external control device can obtain the temperature signal detected by the thermostat in the blister mold in real time through the thermostat plug and the thermostat connector and perform effective control.

[0029] Furthermore, the top of the positioning column is in a conical shape, and the edge of the port of the positioning hole is in a rounded shape.

[0030] Therefore, in this way, the top of the positioning column can be inserted into the positioning hole very quickly. During the positioning process, even if the positioning hole deviates slightly from the positioning column, the positioning column can also be quickly inserted into the positioning hole due to the conical design of the top of the positioning column and the chamfered design of the edge of the positioning hole port.

[0031] Furthermore, it also includes a connecting plate, the first driving device is a cylinder and there are two of them, one end of the connecting plate is fixed to the driving rod of one first driving device, and the other end of the connecting plate is fixed to the driving rod of another first driving device, there are two positioning columns, the bottom of the positioning column is arranged on the connecting plate, and the top of the positioning column extends from the upper surface of the supporting plate.

[0032] Therefore, due to the heavy weight of the blister mold, the driving force to drive the positioning column to move up and down is large, so the two cylinders are used to jointly drive the connecting plate to move up and down, and the connecting plate drives the two positioning columns to move up and down synchronously. In this way, sufficient driving force can be ensured and the two positioning columns can move up and down synchronously, thereby ensuring the precise positioning of the mold fixing plate and the load-bearing plate.

[0033] Furthermore, it also includes a bearing column, which is inserted into the bearing plate and can move up and down in the bearing plate, the bottom of the bearing column is arranged on the connecting plate, and the top of the bearing column extends out from the upper surface of the bearing plate.

[0034] Therefore, the bearing column and the positioning column move up and down synchronously. During the mold changing process, when the mold fixing plate carrying the blister mold descends, the bearing column can assist the positioning column in bearing the weight of the blister mold. When the locking piece locks the mold fixing plate, the bottom of the mold fixing plate is pushed upward by the bearing column and the positioning column, and the top of the mold fixing plate is pressed downward by the locking piece, ensuring that the mold fixing plate and the bearing plate are firmly locked together, ensuring that the plug is firmly inserted into the water outlet, and the vacuum connection plug is firmly inserted into the vacuum connection port.

[0055] See also Figure 5 A positioning hole 105 is formed on the mold fixing plate 100. The position of the positioning hole 105 is adapted to the position of the positioning column 2. The edge of the port of the positioning hole 105 is chamfered. In this embodiment, the number of the positioning holes 105 is two, and the two positioning holes 105 are respectively located at two diagonal positions on the mold fixing plate 100.

[0056] See also Figure 3 , Figure 4 , Figures 10 to 12The positioning column 2 is inserted into the carrier plate 1 and can move up and down in the carrier plate 1. The positioning column 2 is used to abut the mold fixing plate 100. Specifically, a first through hole (not shown) for the positioning column 2 to pass through is formed on the carrier plate 1. The positioning column 2 is inserted into the first through hole. The inner diameter of the first through hole is slightly larger than the outer diameter of the positioning column 2, ensuring that the positioning column 2 can move up and down smoothly in the first through hole. The top of the positioning column 2 is conical, so that the top of the positioning column 2 can be inserted into the positioning hole 105 very quickly. During the positioning process, even if the positioning hole 105 deviates slightly from the positioning column 2, due to the conical design of the top of the positioning column 2 and the rounded design of the edge of the port of the positioning hole 105, the positioning column 2 can also be quickly inserted into the positioning hole 105.

[0057] See also Fig.14 In this embodiment, a boss 21 is integrally formed on the locating column 2 along the circumferential direction, the inner diameter of the locating hole 105 is larger than the outer diameter of the locating column 2, and the inner diameter of the locating hole 105 is smaller than the outer diameter of the boss 21. The locating hole 105 is a through hole style. In this case, when the top of the locating column 2 is inserted into the locating hole 105, the mold fixing plate 100 presses down on the boss 21 of the locating column 2. In other embodiments, the locating hole 105 may also be a blind hole style, and the boss 21 may not be provided on the locating column 2. In this case, when the top of the locating column 2 is inserted into the locating hole 105, the mold fixing plate 100 presses down on the top of the locating column 2. In other embodiments, the positioning hole 105 can be a through hole style, the inner diameter of the positioning hole 105 is smaller than the outer diameter of the positioning column 2, and the boss 21 may not be provided on the positioning column 2. In this case, when the top of the positioning column 2 is inserted into the positioning hole 105, the periphery of the port of the positioning hole 105 is pressed on the conical surface of the top of the positioning column 2, and the mold fixing plate 100 is pressed downward on the conical surface of the top of the positioning column 2.

[0058] The first driving device 3 can drive the positioning column 2 to move up and down in the first through hole on the supporting plate 1.

The two first driving devices 3 can synchronously drive the connecting plate 7 to move up and down ( Figure 1 As shown), the bottom of the positioning column 2 is fixed on the connecting plate 7, and the top of the positioning column 2 passes through the first through hole on the supporting plate 1 and then extends out from the upper surface of the supporting plate 1 ( Figure 4 and Fig.10As shown, a second through hole (not shown) is formed on the bearing plate 1 for the bearing column 8 to pass through, and the bearing column 8 is inserted in the second through hole. The inner diameter of the second through hole is slightly larger than the outer diameter of the bearing column 8, ensuring that the bearing column 8 can move up and down smoothly in the second through hole. The bottom of the bearing column 8 is fixed on the connecting plate 7, and the top of the bearing column 8 passes through the second through hole on the bearing plate 1 and then extends out from the upper surface of the bearing plate 1 ( Figure 4 and Fig.10 As shown in the figure, since the weight of the blister mold is heavy, the driving force for driving the positioning column 2 and the bearing column 8 to move up and down is large, so the two cylinders are used to jointly drive the connecting plate 7 to move up and down, and the connecting plate 7 drives the two positioning columns 2 and the two bearing columns 8 to move up and down synchronously. In this way, sufficient driving force can be ensured and the two positioning columns 2 and the two bearing columns 8 can move up and down synchronously, thereby ensuring the precise positioning of the mold fixing plate 100 and the bearing plate 1. Moreover, since the bearing column 8 and the positioning column 2 move up and down synchronously, during the mold changing process, when the mold fixing plate 100 carrying the blister mold descends, the bearing column 8 can assist the positioning column 2 in jointly bearing the weight of the blister mold. When the locking member 4 locks the mold fixing plate 100, the bottom of the mold fixing plate 100 is held upward by the bearing column 8 and the positioning column 2 ( Figure 1 and Figure 3 As shown), the top of the mold fixing plate 100 is pressed down by the locking member 4, ensuring that the mold fixing plate 100 and the carrier plate 1 are firmly locked together, ensuring that the plug is firmly inserted into the water inlet, the vacuum connection plug 13 is firmly inserted into the vacuum connection port 103, and the thermostat plug 14 is firmly plugged into the thermostat connector 104.

[0059] During the mold changing process, in order to ensure that the top of the positioning column 2 first cooperates with the positioning hole 105 on the mold fixing plate 100, the height of the positioning column 2 is slightly higher than the height of the supporting column 8, and the height of the boss 21 on the positioning column 2 is equivalent to the height of the supporting column 8. Moreover, in order to increase the bearing area of ​​the supporting column 8, the longitudinal section along the axis of the top of the supporting column 8 is T-shaped.

[0060] See also Figure 3 , Figure 4 , Figures 11 to 13 In this embodiment, there are two positioning columns 2 and two bearing columns 8, and the two positioning columns 2 and the two bearing columns 8 are arranged in a square, and the two positioning columns 2 and the two bearing columns 8 are arranged diagonally, so as to ensure that the weight of the mold fixing plate 100 and the blister mold 200 can be stably carried. In other embodiments, the number of positioning columns 2, the number of bearing columns 8 and the distribution positions can be adjusted according to the load-bearing requirements.

[0061] See also Figure 6, the locking member 4 can be inserted into the locking hole 106, and the second driving device can drive the locking member 4 to rotate to buckle on the periphery of the end of the locking hole 106, so as to lock the mold fixing plate 100 and the carrying plate 1 together.

The cylinder 51 and the positioning ring 53 are fixed to the bottom of the bearing plate 1. The locking member 4 is inserted into the positioning ring 53 and can rotate in the positioning ring 53. In order to ensure that the locking member 4 does not fall out of the positioning ring 53, a concave cavity can be formed on the positioning ring 53. A limiting platform 42 ( Figure 7 As shown), the locking member 4 is inserted into the positioning ring 53 and the limit platform 42 is accommodated in the concave cavity on the positioning ring 53, one end of the transmission rod 52 is hinged on the first end 511 of the cylinder, and the other end of the transmission rod 52 is fixed on the first end 401 of the locking member, and the second end 402 of the locking member can extend from the locking hole 106 on the mold fixing plate 100 after passing through the supporting plate 1, and a third through hole (not shown) for the locking member 4 to pass through is formed on the supporting plate 1, and the second end 402 of the locking member can extend from the locking hole 106 after passing through the third through hole on the supporting plate 1, and a cylinder 51 can drive a locking member 4 to rotate through the transmission rod 52 so that the second end 402 of the locking member is buckled on the periphery of the end of the locking hole 106.

When a locking action is required, the cylinder 51 at one end of the connecting rod 6 extends, and at the same time, the cylinder 51 at the other end of the connecting rod 6 retracts. The connecting rod 6 moves in the A direction. The two cylinders 51 can drive the two locking parts 4 to rotate synchronously in the C direction to achieve the locking operation, and it can be ensured that the two locking parts 4 are locked synchronously and smoothly. Another connecting rod 6 can also connect the other two cylinders 51 together. When a locking action is required, the cylinder 51 at one end of the connecting rod 6 extends, and at the same time, the cylinder 51 at the other end of the connecting rod 6 retracts.
