Detailed Description
In order to further describe the technical means and effects adopted by the present invention for achieving the intended purpose, the following detailed description of the specific embodiments of the present invention is given with reference to the accompanying drawings and preferred embodiments.
Referring to fig. 1 to 5, an embodiment of the present invention provides a lower mold structure with a product ejection function, which includes a substrate 1, and a plurality of cores 2 penetrating through the substrate 1, wherein a first ejection opening module 3 and a second ejection opening module 4 are disposed on the substrate 1 and located at the periphery of the cores 2, and the first ejection opening module 3 and the second ejection opening module 4 have the same structure. Taking the first jack-up mold opening assembly 3 as an example for details, the first jack-up mold opening assembly 3 includes a jack-up mold opening driving structure 31 slidably disposed on the substrate 1, and a jack-up slide seat 32 disposed on the jack-up mold opening driving structure 31 and located outside the mold core 2, specifically, the jack-up mold opening driving structure 31 mainly includes a delay guide seat 311, and a driving seat 312 slidably disposed on the substrate 1 and surrounding the periphery of the delay guide seat 311, and the jack-up slide seat 32 is fixedly connected with the driving seat 312, i.e. the jack-up slide seat 32 moves along with the driving seat 312.
Meanwhile, as shown in fig. 3, a plurality of side clamping grooves 321 for clamping the core 2 are formed on one side of the jacking sliding seat 32 close to the core 2, after the jacking sliding seat 32 of the first jacking mold opening assembly 3 and the jacking sliding seat 32 of the second jacking mold opening assembly 4 are combined, the side clamping grooves 321 on the two jacking sliding seats 32 are combined to form a ring groove 320 surrounding the periphery of the core 2, as shown in fig. 4; a cavity 5 for molding the lower end of the product 10 is reserved between the side clamping groove 321 and the core 2, and the product 10 is molded in the cavity 5 and is coated on the periphery of the core 2; meanwhile, the outer side of the product 10 is supported on the upper edge of the side clamping groove 321, specifically, the integrally formed step 101 on the outer side of the product 10 is located on the upper edge of the side clamping groove 321, that is, the step 101 on the outer side of the product 10 is supported by the upper edge of the side clamping groove 321, as shown in fig. 5.
Meanwhile, as shown in fig. 3, the large water gap 30 and the glue inlet channel 40 are disposed on the jack-up slide 32, and the large water gap 30 extends to the inner wall of the side clamping groove 321 to complete the glue dispensing process.
In order to achieve the purpose of ejecting and opening the product 10, the upper die drives the substrate 1 to move upwards for two sections of strokes, in the first section of strokes of the upward movement, the core 2 and the delay guide seat 311 are stationary, and the substrate 1 drives the driving seat 312 of the first ejection opening module 3 and the second ejection opening module 4 to move upwards synchronously with the ejection slide seat 32, then the ejection slide seat 32 applies upward acting force to the product 10 (specifically, the step 101 on the outer side edge of the product 10), the product 10 is ejected, and the product 10 and the core 2 are released, so that the purpose of completely and accurately ejecting the product 10 is achieved. In the second upward movement stroke, the substrate 1 applies an upward acting force to the driving seat 312, and simultaneously, under the guiding action of the delay guide seat 311, the driving seats 312 on the first jacking mold opening assembly 3 and the second jacking mold opening assembly 4 respectively drive the jacking sliding seat 32 to move along the direction away from the product 10, that is, the jacking sliding seats 32 on the first jacking mold opening assembly 3 and the second jacking mold opening assembly 4 are away from the product 10 and are separated from each other, so that the purpose of quick and accurate mold opening is realized.
As shown in fig. 6 to 8, in the combination manner of the delay guide seat 311 and the driving seat 312, in this embodiment, a movable through hole 3121 through which the delay guide seat 311 passes is formed on the driving seat 312, at least one inner guiding inclined plane 3111 is formed on the outer wall of the delay guide seat 311, an outer guiding inclined plane 31211 matching with the inner guiding inclined plane 3111 is formed on the inner wall of the movable through hole 3121 facing the inner guiding inclined plane 3111, and a delay gap 313 is reserved between the inner guiding inclined plane 3111 and the outer guiding inclined plane 31211. Specifically, the inner guide inclined surface 3111 and the outer guide inclined surface 31211 are inclined in order from bottom to top in a direction away from the core 2.
In the first stroke of the upper die driving the substrate 1 to move upwards, no interaction force is generated between the driving seat 312 and the delay guide seat 311 because a delay gap 313 is reserved between the two; when the upward travel is completed, the delay gap 313 between the driving seat 312 and the delay guide seat 311 just disappears.
In the second stroke of the upper mold driving the substrate 1 to move upwards, because the delay gap 313 between the driving seat 312 and the delay guide seat 311 is eliminated, the outer guide inclined surface 31211 on the inner wall of the driving seat 312 moves upwards along the inner guide inclined surface 3111 on the outer wall of the delay guide seat 311 under the pushing of the substrate 1, so that the driving seats 312 on the first jack-up mold opening assembly 3 and the second jack-up mold opening assembly 4 respectively drive the jack-up sliding seat 32 to move along the direction away from the product 10.
As can be seen from the above, the delay guide seat 311 does not function in the first stroke, but functions in the second stroke, i.e. functions as delay guide. After the first stroke is completed (i.e., after the first stroke is delayed), the delay guide seat 311 plays a guiding role to guide the two jack-up slides 32 to mutually realize the purpose of die opening.
Meanwhile, an inner yielding inclined plane 3112 is formed on the outer wall of the delay guide seat 311 facing the core 2, and an outer yielding inclined plane 31211 matching the inner yielding inclined plane 3112 is formed on the inner wall of the movable through hole 3121 facing the inner yielding inclined plane 3112. Specifically, the inner relief inclined surface 3112 and the outer relief inclined surface 31211 are inclined in order from bottom to top in a direction away from the core 2. The inner yielding inclined surface 3112 is matched with the outer yielding inclined surface 31211, so that the delay guide seat 311 better provides a guiding function for the driving seat 312 to drive the jacking sliding seat 32 to move along the direction away from the product 10.
In order to separate the delay guide seat 311 from the substrate 1, when the substrate 1 drives the driving seat 312 to move upwards, the delay guide seat 311 does not move upwards, but is stationary, and in this embodiment, the lower part of the delay guide seat 311 passes through the substrate 1, i.e. the substrate 1 can move up and down along the delay guide seat 311. Specifically, the lower end of the delay guide seat 311 penetrates through the driving seat 312 and the substrate 1 respectively, and is fixed on the base 20 below the lower die structure, as shown in fig. 9.
In this embodiment, in order to match the molding of the product 10, as shown in fig. 3 to 5, an arc surface 322 is formed on the upper portion of the side edge of the jack-up slider 32 near the core 2. The curvature of the arcuate surface 322 matches the curvature of the step 101 on the outside edge of the product 10, thereby facilitating the step 101 on the outside edge of the product 10 to be formed exactly on the arcuate surface 322 on the outside edge of the side detent 321.
As shown in fig. 2, 7 and 8, in the combination manner of the driving seat 312 and the jack-up sliding seat 32, a connection boss 3122 is provided on a side of the driving seat 312 close to the jack-up sliding seat 32, and the jack-up sliding seat 32 is fixedly disposed on the connection boss 3122. Specifically, the jack-up slider 32 is fixed to the connection boss 3122 by a plurality of screws so that the jack-up slider 32 moves along with the driving seat 312.
In order to realize that the driving seat 312 can slide on the substrate 1, in this embodiment, a plurality of sliders 6 are disposed on the substrate 1, and the driving seat 312 is slidably disposed on the sliders 6.
The embodiment of the invention also provides a product ejection and die opening method based on the lower die structure, which comprises the following steps:
(1) The upper die drives the base plate 1 to move upwards for a stroke m, and the base plate 1 drives the driving seat 312 of the first jacking die opening assembly 3 and the second jacking die opening assembly 4 to move upwards synchronously with the jacking sliding seat 32 for the stroke m, in the process, the core 2 and the time delay guide seat 311 are stationary, the jacking sliding seat 32 applies upward acting force to the product 10 to jack the product 10, so that the product 10 and the core 2 are loosened;
(2) The upper die continues to drive the base plate 1 to move upwards for a period of travel n, and the base plate 1 applies upward acting force to the driving seat 312, meanwhile, under the guiding action of the delay guide seat 311, the driving seats 312 on the first jacking and opening assembly 3 and the second jacking and opening assembly 4 respectively drive the jacking sliding seat 32 to move along the direction away from the product 10, namely the jacking sliding seats 32 on the first jacking and opening assemblies 3 and the second jacking and opening assembly 4 are away from the product 10 and separated from each other;
(3) The product 10 is gripped by the robot.
Specifically, in the step (1), in the process that the substrate 1 drives the driving seat 312 and the jack-up sliding seat 32 to move upwards synchronously, no interaction force occurs between the driving seat 312 and the delay guide seat 311 due to the existence of the delay gap 313 therebetween; after the synchronous up-shift m, the delay gap 313 between the driving seat 312 and the delay guide seat 311 disappears.
For a specific value of the stroke m, the stroke m may be set according to a specific requirement, and in practical application, the size of the stroke m corresponds to that of the delay slit 313, that is, after the driving seat 312 moves up the stroke m, the outer guide inclined surface 31211 just contacts with the inner guide inclined surface 3111, that is, the delay slit 313 disappears. Specifically, the stroke m may be set to 20 mm, 30 mm, or the like.
Specifically, in the step (2), since the delay gap 313 between the driving seat 312 and the delay guide seat 311 has disappeared, the outer guide inclined surface 31211 on the inner wall of the driving seat 312 moves up along the inner guide inclined surface 3111 on the outer wall of the delay guide seat 311 under the pushing of the substrate 1, so that the driving seats 312 on the first jack-up mold opening assembly 3 and the second jack-up mold opening assembly 4 respectively drive the jack-up sliding seat 32 to move along the direction away from the product 10.
The specific value of the stroke n can be set according to specific needs, and in practical application, after the stroke n is completed, the distance separating the two jacking sliding seats 32 on the first jacking mold opening assembly 3 and the second jacking mold opening assembly 4 can enable the manipulator to stretch into and clamp the product 10. Specifically, the stroke n may be set to 20 mm, 30 mm, or the like.
By setting two sections of upward moving strokes, in the first section of upward moving stroke, upward acting force is applied to the product by the upward moving of the jacking sliding seat, the product is jacked up, and the product and the mold core are loosened, so that the purpose of quick and accurate ejection of the product is realized. In the second section of upward movement travel, under the guiding action of the delay guide seat, the driving seat drives the jacking sliding seat to move along the direction away from the product, namely the jacking sliding seat is away from the product and separated from each other, so that the purpose of quick and accurate die opening is realized. Therefore, the continuous and orderly execution of the product ejection step and the die opening step is realized, and the rapid processing and forming of the product are facilitated.
When the embodiment is specifically applied, the upper die in the die is required to be matched for use, the upper die plays a role in assisting in driving the substrate 1 to move upwards, and the upper die can be detachably arranged on the substrate 1.
The foregoing is merely a preferred embodiment of the present invention, and the technical scope of the present invention is not limited to the above embodiments, so that other structures using the same or similar technical features as those of the above embodiments of the present invention are all within the scope of the present invention.
