DETAILED DESCRIPTION

[0047] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0048] See also Figure 1 to Figure 10 In the embodiment of the present invention, the synchronous drive mold for maintaining the balance of glue feeding includes: a mold body 1, a pressurizing structure, an extrusion assembly, a trigger 18 and a staggered assembly, so that when the heated glue is extruded into the cover box plate 2, the four groups of sealing plugs 10 can act synchronously, so that the glue can enter the cover box plate 2 synchronously, so as to enter the discharge port 101 synchronously, and ensure that the amount of glue filled in the four groups of discharge ports 101 and the filling speed are consistent, which can ensure the injection molding effect on the one hand, and prevent the amount of material in a certain group of discharge ports 101 from being too little or too much on the other hand, as follows:

[0049] The mold body 1 is provided with a plurality of discharge ports 101;

[0050] The pressurizing structure is provided with multiple groups and is arranged inside the mold body 1. The pressurizing structure can pressurize the discharge port 101. It should be noted that in this embodiment, four groups of discharge ports 101 are provided, and each group of discharge ports 101 is arranged in two rows and six columns. In actual production, the number of groups and arrangement of the discharge ports 101 can be formulated according to actual needs.

[0051] The pressurizing structure comprises a cover box plate 2 which is sealed and fitted with the inner wall of the mold body 1, a pressurizing plate 3 is installed in the cover box plate 2 in a sealing and sliding manner, and a blocking portion 301 which is sealed and fitted with the inner wall of the mold body 1 is formed on the pressurizing plate 3, and the blocking portion 301 can make one group of the discharge ports 101 conductive or blocked when it moves to the end of the stroke;

[0052] It is worth noting that a conducting hole is formed on the side of the cover box plate 2 away from the boost plate 3. When the pressure in the cover box plate 2 increases and the boost plate 3 moves, the conducting hole can discharge the air on the other side of the boost plate 3 to achieve air pressure balance.

[0053] The boosting structure also includes an energy storage kit connected to the boosting plate 3, and the energy storage kit is used to drive the sealing part 301 to seal the discharge port 101. The energy storage kit includes a transverse axis 4 fixedly installed in the covering box plate 2, and the transverse axis 4 is sealingly and slidably connected to the boosting plate 3, and a first cylindrical spring 5 is sleeved on the transverse axis 4, one end of the first cylindrical spring 5 is connected to the side wall of the covering box plate 2, and the other end is connected to the boosting plate 3.

[0054] In the initial state, the first cylindrical spring 5 is in a compressed state, at which time the booster plate 3 abuts against the inner wall of one side of the cover box plate 2 , and in this state, the blocking portion 301 can block the group of discharge ports 101 .

[0055] When the extrusion assembly extrude the heated colloid into the covering box plate 2, the pressure on the side of the booster plate 3 away from the conducting hole will increase, and under the action of the pressure, the booster plate 3 will move toward the conducting hole until one of the rows of discharge ports 101 is connected, at which time the heated colloid can enter the inside of the discharge port 101, and due to the presence of the first cylindrical spring 5, the heated colloid has a pressurized effect, so that it enters the discharge port 101 faster, and when one of the rows of discharge ports 101 is completely filled, when the heated colloid continues to enter the covering box plate 2, the pressure in the covering box plate 2 will continue to increase, and the booster plate 3 will continue to move, until when the booster plate 3 moves to the end of the stroke, another row of discharge ports 101 is connected, at which time the heated colloid will enter the discharge ports 101 in that row again, thereby completing the material injection of this group of discharge ports 101.

[0056] The cover box plate 2 is provided with an electromagnetic conduction valve 6 that can be conducted thereto, and the electromagnetic conduction valve 6 is electrically connected to a trigger switch 22 connected to the staggered assembly;

[0057] When the trigger member 18 moves to the end of the stroke, the clutch assembly can turn on the trigger switch 22 and the electromagnetic conducting valve 6 .

[0058] It should be noted that when the injection of the material is completed, the trigger member 18 just moves to the end of the stroke. At this time, the staggered assembly can trigger the trigger switch 22 to be turned on, so that under the control of the trigger switch 22, the electromagnetic conduction valve 6 is turned on. At this time, the first cylindrical spring 5 can release elastic potential energy, and drive the booster plate 3 to move in the opposite direction, and compress the excess colloid in the cover box plate 2, so that the colloid can flow out to the outside of the cover box plate 2 through the electromagnetic conduction valve 6, thereby avoiding the colloid in the cover box plate 2 solidifying due to cooling in the gap of the injection molding action, and causing the cover box plate 2 to be blocked.

[0059] Based on the above arrangement, on the one hand, when the heated colloid is injected into the cover box plate 2, the two rows of discharge ports 101 can be connected in succession, and the colloid can quickly enter the discharge port 101 under the action of the boost, ensuring that the heated colloid can completely fill the discharge port 101; on the other hand, after the injection molding is completed, the electromagnetic conduction valve 6 is turned on, and when the boost plate 3 moves in the reverse direction, the excess colloid in the cover box plate 2 can be squeezed out, thereby preventing the colloid in the cover box plate 2 from solidifying due to cooling in the gap of the injection molding action, and causing the cover box plate 2 to be blocked.

[0060] It should be emphasized that since the amount of colloid injected into the cover box plate 2 each time is greater than the amount of colloid that the discharge port 101 can accommodate, each discharge port 101 can be filled, thereby avoiding the problem of excessive or insufficient colloid in a certain discharge port 101.

[0061] See also Figure 6~Figure 7 The extrusion assembly is connected to the cover box plate 2, and the extrusion assembly can extrude the externally heated colloid into the pressurized structure;

[0062] The extrusion assembly includes a sealed cylinder 8 disposed in the mold body 1, and two one-way valves are disposed on the sealed cylinder 8, one of which is connected to the cover box plate 2 through a conduit 7. Specifically, the two one-way valves have different conduction directions, one of which is from the outside to the inside of the sealed cylinder 8, and the other is from the inside of the sealed cylinder 8 to the outside;

[0063] The extrusion assembly further comprises a telescopic structure which is sealingly and slidably disposed in the sealing cylinder 8, a connecting plate 12 is disposed at the end of the telescopic structure, and the first convex shaft 13 is rotatably connected to the connecting plate 12;

[0064] The telescopic structure comprises a sealing plug 10 which is sealingly and slidably mounted in the sealing cylinder 8, a telescopic shaft 9 which is perpendicular to the sealing plug 10 is mounted on the sealing plug 10, an end of the telescopic shaft 9 which is away from the sealing plug 10 penetrates the sealing cylinder 8 and is slidably arranged, and the telescopic shaft 9 is detachably connected to the connecting plate 12;

[0065] The telescopic shaft 9 is also sleeved with a second cylindrical spring 11 , one end of the second cylindrical spring 11 is connected to the sealing plug 10 , and the other end is connected to the inner wall of the sealing cylinder 8 .

[0066] In this embodiment, a total of four extrusion components are provided, and the four extrusion components are respectively connected to four boosting structures, and the two extrusion components on the same side are connected by a connecting plate 12. This enables the two extrusion components to move synchronously when the connecting plate 12 is actuated, so that two of the discharge ports 101 are synchronously filled with materials, so that the filling speed of the colloid is consistent.

[0067] When the trigger member 18 is actuated, the trigger member 18 acts on the first convex shafts 13 on both sides thereof, so that the first convex shafts 13 on both sides can move away from each other. At this time, the four groups of extrusion components can be ensured to act synchronously, and the filling speeds of the four groups of discharge ports 101 can be the same.

[0068] When the first convex shaft 13 moves away from each other, the sealing plug 10 can move away from the second cylindrical spring 11 driven by the telescopic shaft 9. At this time, the colloid in the sealing cylinder body 8 can be squeezed and transported to the covering box plate 2 and finally enter the discharge port 101. When the trigger member 18 is separated from the first convex shaft 13, the second cylindrical spring 11 will release its elastic potential energy to reset the sealing plug 10. At this time, negative pressure is generated in the sealing cylinder body 8, thereby drawing the colloid after external heating into the sealing cylinder body 8.

[0069] Through the above arrangement, when the heated colloid is extruded into the cover box plate 2, the four groups of sealing plugs 10 can move synchronously, so that the colloid can synchronously enter the cover box plate 2 and enter the discharge port 101, ensuring that the amount of colloid filled in the four groups of discharge ports 101 and the filling speed are consistent. On the one hand, it can ensure the injection molding effect, and on the other hand, it can prevent the amount of material in a certain group of discharge ports 101 from being too little or too much.

[0070] See also Figure 8~Figure 10The trigger member 18 is arranged in the mold body 1, and the trigger member 18 cooperates with the first convex shaft 13 connected to the extrusion assembly to drive the extrusion assembly to move. Two inclined guide surfaces 1801 are symmetrically arranged on the trigger member 18, and the inclined guide surfaces 1801 cooperate with the first convex shaft 13 to drive the telescopic shaft 9 to move toward the inside of the sealing cylinder 8. Since the two inclined guide surfaces 1801 are symmetrically arranged, the two groups of first convex shafts 13 can move synchronously when being extruded;

[0071] The trigger member 18 is also provided with a slide groove 1802, and the slide groove 1802 is slidably connected with the staggered assembly;

[0072] The staggered assembly is installed in the mold body 1 and connected to the trigger member 18. The staggered assembly can be dislocated with the first convex shaft 13 when the trigger member 18 is reset. The staggered assembly includes a guide plate 14 fixedly installed in the mold body 1, an electric telescopic rod 15 is fixedly installed on the guide plate 14, and a sliding sleeve 16 is slidably installed on the guide plate 14, and the sliding sleeve 16 is connected to the action end of the electric telescopic rod 15;

[0073] The sliding sleeve 16 is also provided with a sliding connection block 17, and the sliding connection block 17 is slidably connected with the slide groove 1802. It should also be noted that a connecting spring (not shown in the figure) is provided between the sliding connection block 17 and the trigger member 18, and the connecting spring drives the sliding connection block 17 to move away from the trigger member 18;

[0074] The staggered assembly further includes a second convex shaft 19 rotatably mounted on the trigger member 18, and the switching plate assembly disposed in the mold body 1 is in rolling cooperation with the second convex shaft 19;

[0075] The switching plate group includes a side plate 20 symmetrically arranged in the mold body 1, and a vertical trough 2001, a first horizontal trough 2002, an inclined trough 2004 and a second horizontal trough 2005 are arranged on the side plate 20, and the vertical trough 2001, the first horizontal trough 2002, the inclined trough 2004 and the second horizontal trough 2005 are connected end to end;

[0076] An extension slot 2003 is disposed at one end of the first horizontal slot 2002 away from the vertical slot 2001, and the extension slot 2003 is colinear with the first horizontal slot 2002;

[0077] A reversing member 21 is rotatably mounted on one end of the inclined slot body 2004 away from the second horizontal slot body 2005 , and a torsion spring is disposed on the rotating shaft of the reversing member 21 .

[0078] In the initial state, the second convex shaft 19 is at one end of the second horizontal groove body 2005 away from the inclined groove body 2004. At this time, when the action end of the electric telescopic rod 15 moves, it can drive the sliding sleeve 16 to move along the length direction of the guide plate 14, thereby causing the trigger member 18 to move. During this process, the second convex shaft 19 always moves along the length direction of the second horizontal groove body 2005, and when the inclined guide surface 1801 on the trigger member 18 abuts against the first convex shaft 13, the inclined guide surface 1801 can drive the two groups of first convex shafts 13 to move away from each other. After the trigger member 18 is separated from the first convex shaft 13, the first convex shaft 13 can be reset. At this time, the trigger member 18 will continue to move, causing the second convex shaft 19 to move along the inclined groove body 2004. At this time, the trigger member 18 will move toward the guide The guide plate 14 moves and is misaligned with the first cam 13. When the second cam 19 moves to the end of the inclined slot 2004, the second cam 19 abuts against the switching member 21 and deflects the switching member 21. Then, the second cam 19 continues to move along the extension slot 2003. After the second cam 19 is separated from the switching member 21, the switching member 21 can be reset. Then, the action end of the electric telescopic rod 15 moves in the opposite direction. At this time, the second cam 19 can move along the first horizontal slot 2002, so that during the resetting process of the trigger member 18, it can not interfere with the first cam 13. When the second cam 19 moves to the end of the stroke, the trigger member 18 is reset under the action of the connecting spring, so that the above action can be repeated when the electric telescopic rod 15 moves next time.

[0079] Through the above arrangement, the trigger member 18 can switch to a position state different from the first convex shaft 13 when in action, ensuring that the two first convex shafts 13 can be driven away from each other while avoiding interference with the first convex shaft 13 when resetting, so that the device can operate in a cycle.
