Description

Technical Field

[0001] The present application relates to the technical field of two-color injection molds, and in particular to a mold with a front mold opening structure. Background Art

[0002] In previous mold designs, the front mold slide relies on the front mold floating plate to drive the mold opening. After the mold is opened, the hot runner is lower than the front mold parting surface, and it is impossible to perform air injection to clean the residual glue in the hot runner. These rubber materials have been degraded to a certain extent. If there is glue overflow from the hot nozzle when injected into the mold, it is easy to cause mold sticking problems. In addition, after the mold is opened, if the hot runner automatically overflows glue, it will also cause problems such as mold compression and mold cracking.

[0003] With respect to the above-mentioned related technologies, the inventors believe that there are defects in that the mold is prone to glue overflow and mold cracking when the mold is opened. Utility Model Content

[0004] The present application provides a mold with a front mold behavior mold opening structure to solve the defects of traditional hot runner injection molds that easily cause glue overflow and mold cracking during mold opening.

[0005] In order to solve the above technical problems, a technical solution adopted in the present application is: providing a mold with a front mold acting as a mold opening structure, the mold with the front mold acting as a mold opening structure includes a sliding locking mechanism, and the sliding locking mechanism includes:

[0006] A locking slider, wherein a sliding groove is disposed on the first surface of the locking slider, a sliding connecting plate is disposed in the sliding groove, and the sliding groove is open at one end on the locking slider, and the length of the sliding connecting plate is greater than the length of the sliding groove;

[0007] A fixing platform, arranged on a side of the first surface of the locking slider away from the opening end, and a connecting column is further arranged on the fixing platform;

[0008] The first connecting block is arranged on the first surface of the locking sliding block.

[0009] Preferably, the sliding locking mechanism further comprises a limit stopper, which is arranged on a side of the locking slider close to the opening end, and when the first connecting block slides to the side of the opening end of the locking slider, the first connecting block is restricted from sliding by the limit stopper.

[0010] Preferably, the sliding locking mechanism also includes a floating block, which is arranged on one side of the sliding connecting plate within the sliding groove, and is used to lift the first connecting block to float when the sliding connecting plate slides to the position of the first connecting block, so that the first connecting block floats over the limit stop block.

[0011] Preferably, the thickness of the floating block is greater than the thickness of the limit stopper, so that when the floating block lifts the first connecting block, the first connecting block has appropriate space to pass over the limit stopper.

[0012] Preferably, the sliding locking mechanism further comprises a second connecting block, and the second connecting block is arranged on a side of the sliding connecting plate outside the sliding groove.

[0013] Preferably, the mold with a front mold behavior mold opening structure also includes a rear mold floating plate, and first assembly grooves are arranged on the outer sides of both ends of the rear mold floating plate. The first assembly groove is fixedly connected to the second connecting block by bolts. When opening the mold, the rear mold floating plate drives the sliding connecting plate to move first.

[0014] Preferably, the mold with a front mold behavior mold opening structure also includes a rear mold plate, the rear mold plate is assembled on the rear mold floating plate, second assembly grooves are arranged on both sides of the rear mold plate corresponding to the positions of the first assembly grooves, the second assembly grooves are fixedly assembled with the first connecting block, and when the first connecting block floats over the limit block, the first connecting block and the rear mold plate are disengaged from the sliding locking mechanism.

[0015] Preferably, the mold with a front mold behavior mold opening structure also includes a front template, and third assembly grooves are arranged on both sides of the front template corresponding to the first assembly groove and the second assembly groove. The third assembly groove is fixedly connected to the fixed platform through the connecting column. When the rear mold floating plate is retreated first, the sliding connecting plate slides in the sliding groove. During this process, the front template and the rear template are locked and motionless until the floating block on the sliding connecting plate lifts the first connection block to pass over the limit block, so that the front template and the rear template are unlocked and separated from the mold.

[0016] Preferably, the mold with a front mold behavior mold opening structure further includes:

[0017] A rear mold shovel machine is arranged on the rear mold floating plate, a fourth assembly groove is arranged on the rear mold floating plate, and the rear mold shovel machine is assembled in the fourth assembly groove;

[0018] An inclined guide column, fixedly connected to the rear die shovel machine;

[0019] A slider block is arranged on the front template near the fourth assembly groove. When the front template, the rear template and the rear template floating plate are assembled together, the slider block is sleeved on the inclined guide column, and the side of the shovel machine away from the rear template floating plate is also clamped in the front template;

[0021] Preferably, the floating block is a trapezoidal structural block, and both sides of the floating block in the direction of the sliding groove are inclined structures rising from outside to inside, which are used to lift the first connecting block so that the first connecting block floats over obstacles.

[0022] The beneficial effect of the present application is that by arranging a shovel and an inclined guide column on the rear mold floating plate, the rear mold floating plate is first separated from the rear mold template from the rear mold floating plate when opening the mold. Since the sliding locking mechanism first locks the front template and the rear template when the rear mold floating plate is withdrawn from the mold, until the rear mold floating plate is withdrawn to a certain distance, the sliding locking mechanism lifts the first connecting block through the sliding connecting plate to float over the obstacle, thereby releasing the lock, unlocking the front template and the rear template to separate the molds, completing the segmented mold separation, and improving the safety of the mold when opening the mold.

[0033] See also Figure 1-Figure 5 As shown, the present application provides a mold with a front mold acting as a mold opening structure, wherein the mold with a front mold acting as a mold opening structure includes a sliding locking mechanism 10, and the sliding locking mechanism 10 includes a locking slider 11, a sliding connecting plate 12, a fixed platform 13, a connecting column 14, and a first connecting block 15.

[0034] A sliding groove is provided on the first surface of the locking slider 11, a sliding connecting plate 12 is provided in the sliding groove, and the sliding groove is open at one end of the locking slider 11, the length of the sliding connecting plate 12 is greater than the length of the sliding groove, a fixed platform 13 is provided on the side of the first surface of the locking slider 11 away from the open end, a connecting column 14 is further provided on the fixed platform 13, a first connecting block 15 is provided on the first surface of the locking slider 11, the first connecting block 15 is connected to the rear template 30, and the fixed platform 13 is connected to the front template 40 through the connecting column 14.

[0035] See also Figure 1 , Figure 3 , Figure 4 As shown, the sliding locking mechanism 10 also includes a limit stopper 16, which is arranged on the side of the locking slide block 11 close to the opening end. When the first connecting block 15 slides to the side of the opening end of the locking slide block 11, it is restricted from sliding by the limit stopper 16. One end of the sliding connecting plate 12 is fixedly connected to the rear mold floating plate 20. When the mold is opened, the rear mold floating plate 20 first retreats backward. At this time, the first connecting block 15 is blocked by the limit stopper 16 and cannot retreat backward, so that the front mold plate 40 and the rear mold plate 30 are locked and cannot be separated, thereby making the rear mold The floating plate 20 and the rear mold plate 30 are separated before the rear mold plate 30 and the front mold plate 40, until the rear mold floating plate 20 retreats to a certain distance, driving the sliding connecting plate 12 to slide backward in the sliding groove, lifting the first connecting block 15 to float over the limit stopper 16, and the rear mold plate 30 and the first connecting block 15 are disengaged from the sliding locking mechanism 10, thereby unlocking the front mold plate 40 and the rear mold plate 30, and then the front mold plate 40 and the rear mold plate 30 can be unlocked and separated only after the rear mold floating plate 20 retreats a certain distance.

[0036] See also Figure 1 , Figure 4As shown, the sliding locking mechanism 10 also includes a floating block 17, which is arranged on the sliding connecting plate 12 and located on one side of the sliding groove, and is used to lift the first connecting block 15 and float it when the sliding connecting plate 12 slides to the position where the first connecting block 15 is located, so that the first connecting block 15 floats over the limit stopper 16. The thickness of the floating block 17 is greater than the thickness of the limit stopper 16, so that when the floating block 17 lifts the first connecting block 15, the first connecting block 15 has a suitable space to pass over the limit stopper 16. The floating block 17 is a trapezoidal structural block, and the two sides of the floating block 17 in the direction of the sliding groove are inclined structures rising from the outside to the inside, which are used to lift the first connecting block 15 and make the first connecting block 15 float over obstacles. One end of the sliding connecting plate 12 is connected to the rear mold floating The plate 20 has a floating block 17 on the other end. The floating block 17 is used when the sliding connecting plate 12 slides a certain distance, that is, when the rear mold floating plate 20 withdraws a certain distance, the floating block 17 arrives at the position of the first connecting block 15. Since the first connecting block 15 is blocked by the limit stopper 16 at this time, the front template 40 and the rear template 30 are locked and cannot be separated. The floating block 17 lifts the first connecting block 15 through the inclined wall set on the side. Since the height of the floating block 17 is greater than the height of the limit stopper 16, the first connecting block 15 has a suitable space to avoid the limit stopper 16. At this time, the rear mold floating plate 20 retreats, and the rear template 30 is unlocked from the front template 40, so that the rear template 30 is driven by the rear mold floating plate 20 to separate from the front template 40.

[0037] See also Figure 1-Figure 5 As shown, the sliding locking mechanism 10 also includes a second connecting block 18, and the second connecting block 18 is arranged on the sliding connecting plate 12 and is located on the side outside the sliding groove. The mold with a front mold behavior mold opening structure also includes a rear mold floating plate 20, and the outer sides of both ends of the rear mold floating plate 20 are provided with first assembly grooves 21. The first assembly groove 21 is fixedly connected to the second connecting block 18 by bolts. When opening the mold, the rear mold floating plate 20 drives the sliding connecting plate 12 to move first.

[0038] The mold with a front mold behavior mold opening structure also includes a rear mold plate 30, which is assembled on the rear mold floating plate 20. Second assembly grooves 31 are arranged on both sides of the rear mold plate 30 corresponding to the positions of the first assembly grooves 21. The second assembly grooves 31 are fixedly assembled with the first connecting block 15. When the first connecting block 15 floats over the limit stop block 16, the first connecting block 15 and the rear mold plate 30 are disengaged from the sliding locking mechanism 10, thereby completing the unlocking of the front mold plate 40 and the rear mold plate 30.

[0039] The mold with a front mold behavior mold opening structure also includes a front template 40. Third assembly grooves 41 are arranged on both sides of the front template 40 at positions corresponding to the first assembly grooves 21 and the second assembly grooves 31. The third assembly grooves 41 are fixedly connected to the fixed platform 13 through connecting columns 14. When the rear mold floating plate 20 is retreated first, the sliding connecting plate 12 slides in the sliding groove. During this process, the front template 40 and the rear template 30 are locked and motionless until the floating block 17 on the sliding connecting plate 12 lifts the first connecting block 15 to pass over the limit block 16, so that the front template 40 and the rear template 30 are unlocked and molded.

[0040] The mold with a front mold behavior mold opening structure further includes a rear mold scraper 22 , an inclined guide column 24 , and a slide block 50 .

[0041] The rear mold shovel machine 22 is arranged on the rear mold floating plate 20, and a fourth assembly groove 23 is arranged on the rear mold floating plate 20. The rear mold shovel machine 22 is assembled in the fourth assembly groove 23. The inclined guide column 24 is fixedly connected to the rear mold shovel machine 22. The slider block 50 is arranged on the front template 40 near the fourth assembly groove 23. When the front template 40, the rear template 30 and the rear mold floating plate 20 are assembled together, the slider block 50 is sleeved on the inclined guide column 24, and the side of the shovel machine away from the rear mold floating plate 20 is also clamped in the front template 40. The rear mold shovel machine 22, the inclined guide column 24, and the slider block 50 are used to improve the stability of the front template 40, the rear template 30, and the rear mold floating plate 20 when the mold is closed. In the prior art, most of them set the floating plate on the front template 40 and set it as the front mold floating plate. In the front mold floating plate, the front mold slide is driven by the front mold floating plate to drive the mold opening. After the mold is opened, the hot runner is lower than the front mold parting surface, and it is impossible to perform air injection to clean the residual glue in the hot runner. These glues have been degraded to a certain extent. If there is glue overflow from the hot nozzle when injected into the mold, it is easy to cause mold sticking problems. In addition, after the mold is opened, if the hot runner automatically overflows glue, it will also cause problems such as mold pressing and mold cracking. Therefore, a rear mold floating plate 20 is provided, and a shovel machine and an inclined guide column 24 are provided on the rear mold floating plate 20. The rear mold floating plate 20 and the rear mold plate 30 are separated from the front mold plate 40 and the rear mold plate 30 before the front mold plate 40 and the rear mold plate 30. The segmented mold separation improves the safety of the mold separation process, and avoids the problem of mold pressing caused by the front mold floating plate, the hot runner being lower than the parting surface after the mold is opened, and the glue cannot be cleaned or the hot runner overflows glue.

[0042] 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.
