Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose, the following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings and preferred embodiments.

Referring to fig. 1 and 2, an embodiment of the present invention provides a product ejection and demolding device, including a substrate 1, at least one core 2 disposed on the substrate 1, two sets of insert pulling mechanisms 3 disposed on the substrate 1 and disposed at the periphery of the core 2, and an ejection mechanism 4 disposed below the substrate 1.

Specifically, as shown in fig. 3, the insertion and extraction mechanism 3 includes at least one sliding guide seat 31, a driving seat 32 slidably disposed on the substrate 1 and surrounding the sliding guide seat 31, and an extraction slide 33 disposed on the driving seat 32 and located outside the upper portion of the core 2. The inlaid portion 20 on the side of the product 10 is located on the pull-out slide 33, as shown in fig. 2, 4 and 6, the inlaid portion 20 on the side of the product 10 is embedded in the pull-out slide 33, and the end of the inlaid portion 20 extends to the side of the product 10 and is embedded in the side of the product 10, so that the inverted structure 101 is formed on the product 10. After the product 10 is molded, the insert portion 20 needs to be pulled out from the product 10 when the mold is released.

In the present embodiment, specifically, the number of the sliding guide seats 31 is two. The sliding guide seat 31 is used for guiding the moving direction of the moving seat 32, so that the moving seats 32 on the two sets of embedding and pulling-out mechanisms 3 drive the pulling-out sliding seats 33 to move in opposite directions, and the embedding parts 20 on the pulling-out sliding seats 33 can be driven to be pulled out from the products 10.

Specifically, as shown in fig. 1 and 10, the ejecting mechanism 4 includes a base 41 disposed below the substrate 1, an upper supporting base 42 disposed below the base 41, and at least one upper supporting linkage assembly 43 respectively connected to the upper supporting base 42 and the base 41, and specifically, a distance is reserved between the upper supporting base 42 and the base 41. Specifically, the number of the top linkage assemblies 43 is two, and the two top linkage assemblies are oppositely arranged at two ends of the top base 42. In this embodiment, the top linkage assembly 43 includes a top linkage block 431 connected to the top base 42 and a top guide block 432 connected to the base 41, and the top linkage block 431 is surrounded on two sides of the top guide block 432, so that when the top base 42 is acted by an upward force, the top base 42 simultaneously exerts the upward force on the top linkage block 431, and the top linkage block 431 vertically moves up along the top guide block 432, thereby improving the stability of the top guide block 432 moving up.

Meanwhile, a limit slider 11 positioned above the upper linking block 431 is convexly arranged at the end of the substrate 1 in a sliding manner, and a pushing bump 4321 for pushing the limit slider 11 is convexly arranged at one side of the upper top guide block 432 close to the substrate 1. In the initial state, a distance is provided between the top trace 431 and the position-limiting slider 11, and the portion of the position-limiting slider 11 protruding outside the substrate 1 is located below the pushing projection 4321 of the top guide block 432, as shown in fig. 10. Therefore, when the upper top linkage block 431 moves upwards to the upper end to contact with the limit slide block 11, the first stroke is obtained; the upper jacking linkage block 431 continuously moves upwards to push the limiting slide block 11 to synchronously move upwards until the limiting slide block 11 is pushed into the substrate 1 by the pushing lug 4321, so that the limiting slide block 11 is separated from the upper jacking linkage block 431, and the second section of stroke is realized; the top linkage block 431 continues to move upwards as a third stroke.

As shown in fig. 2, a nozzle pin 5 sequentially penetrating through the substrate 1 and the base 41 is arranged below a glue inlet channel 40 connected with a nozzle 30 (stub bar) on the side of the product 10, and the nozzle pin 5 is connected with an upper top base 42; at least one product push rod 6 is arranged at the side of the core 2 and is positioned at the lower end of the product 10 and sequentially penetrates through the substrate 1 and the base 41, and the product push rod 6 is connected with the upper push base 42.

Meanwhile, as shown in fig. 14, a plurality of movable cavities 420 are formed in the upper base 42, a boss 61 is formed at the lower portion of the product push rod 6, and the lower end of the product push rod 6 is inserted into the movable cavities 420 and is clamped in the movable cavities 420 by the boss 61.

In the first stroke, the upward movement of the upper ejection base 42 applies an upward acting force to the nozzle ejector rod 5, so that the nozzle ejector rod 5 ejects the nozzle 30 and the glue inlet flow channel 40 together, and the nozzle 30 is separated from the product 10. In the process, due to the existence of the movable cavity 420 in the upper top base 42, after the upper top base 42 moves upwards for the first stroke, the boss 61 at the lower part of the product push rod 6 just contacts with the lower side of the movable cavity 420, so in the process, no force is applied to the product push rod 6 by the upper top base 42, and the product push rod 6 does not move upwards.

In the second stroke, when the limiting slide block 11 moves upwards synchronously, the limiting slide block 11 applies an upward acting force to the substrate 1, so that the substrate 1 moves upwards synchronously, in the process, under the guiding action of the sliding guide seat 31, the driving seats 32 on the two sets of embedding and pulling-out mechanisms 3 respectively drive the pulling-out slide seat 33 to move along the direction away from the product 10, the pulling-out slide seat 33 is away from the product 10 and is separated from each other, and then the embedding part 20 on the pulling-out slide seat 33 is pulled out from the product 10. In the process, the upper ejection base 42 drives the product ejector rod 6 to move upwards, and the substrate 1 drives the mold core 2 to move upwards, so that the product ejector rod 6, the mold core 2 and the sliding guide seat 31 move upwards synchronously.

In the third stroke, the upward movement of the upper ejection base 42 applies an upward acting force to the product ejector rod 6, so that the product ejector rod 6 ejects the product 10 upward, and the product 10 is demolded. In this process, the substrate 1 is stationary, the core 2 provided on the substrate 1 is also stationary, and the product lift pins 6 move upward relative to the core 2 to lift the product 10 on the core 2 upward.

Therefore, through three strokes, the water ejecting port 30, the drawing-off embedding part 20 and the product 10 can be ejected in sequence, and the demoulding operation is completed.

In the process of moving up the limit slider 11, in order to enable the limit slider 11 to move to the side of the pushing projection 4321, so that the pushed projection 4321 can be smoothly pushed into the substrate 1, as shown in fig. 10 and 11, in this embodiment, an upper guiding inclined plane 111 is formed at the end of the limit slider 11, and a lower guiding inclined plane 43211 matched with the upper guiding inclined plane 111 is formed at the lower end of the pushing projection 4321. The upper guiding inclined plane 111 and the lower guiding inclined plane 43211 are combined to provide a guiding function for the movement process of the limit slider 11 to withdraw the substrate 1. Therefore, in the process of moving up the limiting slider 11, the pushing bump 4321 pushes the limiting slider to move laterally until the limiting slider is completely retracted into the substrate 1, so as to provide a yielding space for the continuous upward movement (third stroke) of the top-pushing linkage block 431. Therefore, the special structure of the pushing projection 4321 on the top guide block 432 can provide a guiding and pushing effect for the substrate 1 retracting process of the limit slider 11.

As shown in fig. 10, a U-shaped groove 4311 is formed at the upper end of the upper pushing block 431, and the U-shaped groove 4311 surrounds the periphery of the upper pushing guide block 432, i.e. the lower portion of the upper pushing guide block 432 is inserted into the U-shaped groove 4311. When the upper lifting linkage block 431 is forced to move upwards, the inner wall of the U-shaped groove 4311 can vertically move upwards along the outer wall of the upper lifting guide block 432, so that the stability of the upper lifting guide block 432 moving upwards is improved. Therefore, the top guide block 432 is provided to guide the vertical upward movement of the top linkage block 431.

For the installation of the limiting slide block 11, as shown in fig. 11 to 13, in this embodiment, a sliding groove 12 for the limiting slide block 11 to be embedded and slide is formed on the end portion of the substrate 1 close to the top guide block 432, at least one spring limiting groove 112 is formed in the limiting slide block 11, specifically, the number of the spring limiting grooves 112 may be two, a telescopic return spring 113 is disposed in the spring limiting groove 112, and the outer end of the telescopic return spring 113 abuts against the inner wall of the sliding groove 12. When the limit slider 11 is pushed by the pushing projection 4321 to return into the sliding groove 12, the retractable return spring 113 is compressed, and after the limit slider 11 is separated from the pushing projection 4321, the limit slider 11 is returned by the elastic restoring force of the retractable return spring 113, and the end part of the limit slider extends out of the sliding groove 12.

In order to improve the stability provided by the limit slider 11, a strip-shaped guide groove 114 is formed at the upper end of the limit slider 11, a guide shaft 13 extending into the strip-shaped guide groove 114 is arranged on the inner wall of the sliding groove 12 in a downward extending manner, and in two processes of extending the limit slider 11 out of the substrate 1 and retracting the limit slider back into the substrate 1, the guide shaft 13 and the strip-shaped guide groove 114 are combined to provide a guiding effect, so that the limit slider 11 generates linear transverse displacement, and the stability of transverse movement of the limit slider 11 is improved. Meanwhile, two inner side edges opposite to the sliding groove 12 are respectively provided with a limiting slide rail 14, the limiting slide block 11 extends and retracts along the limiting slide rail 14 in a sliding mode, the limiting slide rail 14 is arranged to provide a guiding effect for the extending and retracting action processes of the limiting slide block 11, and the stability of the transverse movement of the limiting slide block 11 is further improved. The strip-shaped guide groove 114 on the limiting slide block 11, the guide shaft 13 on the sliding groove 12 and the limiting slide rail 14 in the sliding groove 12 are combined to provide double guiding functions for the moving direction of the limiting slide block 11, so that the accuracy and the stability of the moving action of the limiting slide block 11 are improved.

Meanwhile, as shown in fig. 13, the lower portion of the sliding guide seat 31 passes through the substrate 1 and is limited on the base 41, so that the sliding guide seat 31 is separated from the substrate 1, and when the substrate 1 drives the driving seat 32 to move upwards, the sliding guide seat 31 does not move upwards, but is stationary, so as to provide a guiding effect on the moving direction of the driving seat 32.

In the second stroke, the substrate 1 moves upward to apply an upward acting force to the moving seat 32, and since the sliding guide seat 31 penetrates through the substrate 1 and is stationary, the outer guide inclined surface 3211 on the inner wall of the moving seat 32 moves upward along the inner guide inclined surface 311 on the outer wall of the sliding guide seat 31, and since the inner guide inclined surface 311 and the outer guide inclined surface 3211 are sequentially inclined from bottom to top toward the direction away from the core 2, the moving seats 32 on the two sets of inlay take-off mechanisms 3 respectively drive the take-off slide 33 to move along the direction away from the product 10, the take-off slide 33 is away from the product 10 and is separated from each other, and the inlay part 20 on the take-off slide 33 is taken away from the product 10.
