Description

A movable insert mechanism for inserting and forming hardware parts Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a movable insert mechanism for a hardware part insertion molding mold. Background Technology

[0002] In the field of metal part insertion injection molding technology, traditional production methods have many drawbacks, seriously hindering the industry's efficient development. Currently, most metal part insertion molding operations rely on manual operation, and the insertion positions are not movable insert structures. This situation has led to a series of problems that urgently need to be solved.

[0003] Manually inserting hardware into the mold is extremely difficult. Due to the lack of precise guidance from movable inserts, workers cannot ensure that the hardware is placed accurately in the target position on the mold every time. This difficulty is particularly pronounced for molds with complex structures and high precision requirements. Inaccurate placement of the hardware can easily lead to mold-closing accidents during the mold closing process, causing mold damage. Mold repair costs are high, including not only the cost of replacing damaged parts but also the production capacity loss caused by production line downtime during repairs.

[0004] The process of manually placing hardware components is extremely time-consuming. Workers need to pick up each component one by one, carefully align it with the mold position, and then insert it, which significantly lengthens the product's molding cycle. In large-scale production, the increased time cost directly leads to low production efficiency. In addition, during manual operation, workers are in a state of high tension for extended periods, needing to constantly monitor the placement of the hardware components, resulting in immense labor intensity.

[0005] Due to the inefficiency of manual operation, plastic material remains in the molding machine barrel for too long. Prolonged exposure to high temperatures makes the material highly susceptible to scorching. This scorched material produces defects such as black spots and bubbles, which can contaminate the finished product, increasing the amount of dirt and foreign matter. Furthermore, improper placement of metal parts can lead to collisions with the mold during injection molding, scratching the product and further reducing the yield rate, significantly increasing production costs.

[0006] To address these challenges, Chinese utility model patent CN222819421U discloses "An Embedded Molding Production Line for Hardware Parts." This design attempts to improve the ease of loading hardware parts by incorporating a base, a moving component, and a feeding assembly on the production line. The working principle involves installing the base on one side of the molding die. By adjusting the sliding of the moving component on the base, the feeding assembly transports the hardware parts above the molding die, where they then fall onto the die. This patented technology can reduce the time spent by workers placing hardware parts individually, theoretically improving production efficiency. However, in practical applications, this patented technology has limitations, such as poor adaptability. When companies need to produce different models of products or change hardware parts of different specifications, cumbersome adjustments are required to the clamping components and adjusting rods of the feeding assembly, and sometimes some tooling needs to be remade. After remaking, each part needs to be repositioned, aligned, and adjusted. This process is not only time-consuming and labor-intensive but also leads to prolonged production line downtime, severely impacting the continuity and efficiency of production.

[0007] In summary, existing technologies have serious shortcomings in terms of production efficiency, product quality, versatility for different specifications of hardware parts, and degree of automation in metal part insertion molding. This paper proposes to develop a novel movable insert mechanism for metal part insertion molding dies. By improving adaptability and automation, this mechanism aims to overcome the deficiencies of existing technologies and meet the urgent needs of the injection molding industry. Summary of the Invention

The hardware component is inserted into a pre-reserved position of the hardware component insert. The hardware component insert guide block is connected to the bottom of the hardware component insert via a pin. The hardware component insert and the hardware component insert guide block are embedded in the rear mold core. The hardware component insert ejector pin and the hardware component insert guide block ejector pin are fixed to the front and rear ejector plates. The base slider device is disposed in the rear mold plate, and the base slider is engaged with the hardware component insert guide block notch.

[0011] Furthermore, the hardware insert has an installation area adapted to the hardware, which is located on the surface of the hardware insert and has a shape that fits the hardware. The hardware insert and the hardware insert guide block are connected by a pin to ensure that the hardware insert and the hardware insert guide block are firmly connected and will not be relatively displaced during the mold operation.

[0012] Furthermore, the length of the hardware insert ejector pin and the hardware insert guide block ejector pin is shorter than that of the other ejector pins. The hardware insert ejector pins are distributed in a central position near the bottom of the hardware part where the hardware insert is installed, and the hardware insert guide block ejector pins are distributed in a central position near the bottom of the hardware insert guide block.

[0013] Furthermore, the base slider device also includes a base slider housing, a base slider hole, a base slider fixing bolt, a base slider spring, and a base slider device spring; the base slider housing has a rear cylindrical and front cuboid space near the mold core, and the base slider spring is installed in this space, wherein the cuboid space is used to place the base slider; the base slider spring is located behind the base slider, and the base slider housing has a cylindrical space on the side away from the mold core where the base slider device spring is installed.

[0014] Furthermore, the middle position of the base slider is provided with a through base slider hole. The shape of the base slider hole is a cylindrical through hole with semicircles on both sides (with a movable distance for sliding back and forth inside). The base slider fixing bolt passes through the base slider hole and fixes the base slider spring and the base slider in the space reserved for it in the base slider shell.

[0015] Furthermore, the base-locking slider device also includes a base-locking slider fixing block through hole, a base-locking slider fixing block through hole inclined surface, a base-locking slider fixing block, and a base-locking slider fixing block inclined surface; the base-locking slider fixing block through hole penetrates the base-locking slider housing, the upper section of the base-locking slider fixing block is located in the base-locking slider fixing block through hole, the bottom of the base-locking slider fixing block is fixed to the front and rear ejector plates, the base-locking slider fixing block through hole is provided with the base-locking slider fixing block through hole inclined surface, the upper section of the base-locking slider fixing block is provided with the base-locking slider fixing block inclined surface, and the base-locking slider fixing block through hole inclined surface and the base-locking slider fixing block inclined surface are matched and connected to each other.

[0016] Furthermore, the buckle base slider device achieves buckling by cooperating with the notch of the hardware insert guide block, thus tightly fastening and fixing the hardware insert guide block.

[0017] Furthermore, the rear mold core is provided with a mounting groove adapted to the hardware insert and the hardware insert guide block. The mounting groove is located on the cavity side of the rear mold core used for molding the product. The shape and size of the mounting groove match the shape of the hardware insert and the hardware insert guide block. After the hardware insert and the hardware insert guide block are installed in the mounting groove, their top surfaces are flush with the cavity surface of the rear mold core, ensuring that the plastic material can evenly wrap the hardware during injection molding.

[0018] Furthermore, the front end face of the latch base slider is an inclined surface.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1.

Through multifaceted structural design improvements, including improvements to the design and structure of each component, as well as improvements to the position and fit relationship, its adaptability is greatly improved. At the same time, it can also solve problems in existing technologies such as difficulty in inserting hardware parts, easy mold compression due to improper placement, long material feeding time, low safety factor, low product yield, and high cost.

[0021] 2. This utility model significantly shortens the molding cycle by setting up a movable insert mechanism. By reducing difficulties in inserting hardware and minimizing misplacement, it avoids mold compression and effectively improves the product yield.

[0022] 3. The structural design and coordination of the various parts of this utility model can support automated operation; through automated operation, labor costs are reduced and safety in the production process is improved.

[0023] 4. This utility model has a high degree of automation. During the operation, the hardware and inserts are assembled outside the mold. After the injection is completed, the ejector plate pushes the ejector pin to eject the product, and the short ejector pin ejects the insert with a delay. The base slider fixing part pushes open the base slider and releases its fastening to the insert guide block. The short ejector pin then ejects the insert and the guide block and separates from the rear mold core. The robot arm takes away the product and the old insert and inserts the new insert with the pre-installed hardware into the rear mold core. The base slider is re-fastened, realizing the cycle operation.

[0024] 5. The key feature of this utility model is that through various design improvements, it can realize the pre-assembly, ejection and automated part changing of movable inserts by robotic arms, shorten the molding cycle, improve product yield, and can be widely applied to the efficient insert molding of hardware and plastics.

[0045] Example

[0046] Referring to Figures 1-16, the movable insert mechanism for inserting metal parts into a molding die provided by this utility model is designed to improve its adaptability and enable it to be adapted for automated operation. It includes a metal part 1, a metal part insert 2, a metal part insert ejector pin 3, a metal part insert guide block 4, a metal part insert guide block notch 401, a metal part insert guide block ejector pin 5, a base slider device 6, a base slider 602, front and rear ejector plates 7, and a rear mold core 8. The metal part... 1. Insert the hardware insert 2 into the reserved position; the hardware insert guide block 4 is connected to the bottom of the hardware insert 2 by a pin; the hardware insert 2 and the hardware insert guide block 4 are embedded in the rear mold core 8; the hardware insert ejector pin 3 (bar-shaped, single strip) and the hardware insert guide block ejector pin 5 are fixed on the front and rear ejector plates 7; the base slider device 6 is set in the rear mold plate, and the base slider 602 is connected to the hardware insert guide block notch 401.

[0047] The hardware insert 2 has an installation area adapted to the hardware 1. The installation area is located on the surface of the hardware insert 2 and its shape fits (matches) the hardware 1. The hardware insert 2 and the hardware insert guide block 4 are connected by a pin to ensure that the connection between the hardware insert 2 and the hardware insert guide block 4 is stable and that no relative displacement occurs between them during the mold operation.

[0048] The lengths of the hardware insert ejector pin 3 and the hardware insert guide block ejector pin 5 (rod-shaped, single strip) are both shorter than the other ejector pins. The hardware insert ejector pin 3 is located in the center near the bottom of the part of the hardware insert 2 where the hardware 1 is installed, and the hardware insert guide block ejector pin 5 is located in the center near the bottom of the hardware insert guide block 4.

[0049] The base-locking slider device 6 also includes a base-locking slider housing 601, a base-locking slider hole 603, a base-locking slider fixing bolt 604, a base-locking slider spring 605, and a base-locking slider device spring 606; the base-locking slider housing 601 has a cylindrical rear section and a rectangular front section space (through groove) on the side near the mold core, in which the base-locking slider spring 605 is installed, and the rectangular space is used to place the base-locking slider 602; the base-locking slider spring 605 is located behind the base-locking slider 602, and the base-locking slider housing 601 has a cylindrical space on the side away from the mold core to house the base-locking slider device spring 606.

[0050] The base slider 602 has a through-hole 603 at its middle position. The shape of the base slider hole 603 is an elliptical cylindrical groove with two identical semi-circular arcs on both sides (with a certain range of movement in the middle to allow the base slider fixing bolt 604 to slide within it). The base slider housing 601 is also fixed with a base slider fixing bolt 604, which passes through the base slider hole 603 to fix the base slider spring 605 and the base slider 602 in the space reserved for them in the base slider housing 601.

[0051] The base-locking slider device 6 further includes: a base-locking slider fixing block through hole 607, a base-locking slider fixing block through hole inclined surface 608, a base-locking slider fixing block 609, and a base-locking slider fixing block inclined surface 610; the base-locking slider fixing block through hole 607 penetrates the base-locking slider housing 601, the upper section of the base-locking slider fixing block 609 is located in the base-locking slider fixing block through hole 607, the bottom of the base-locking slider fixing block 609 is fixed on the front and rear ejector plates 7, the base-locking slider fixing block through hole 607 is provided with a base-locking slider fixing block through hole inclined surface 608, the upper section of the base-locking slider fixing block 609 is provided with a base-locking slider fixing block inclined surface 610, and the base-locking slider fixing block through hole inclined surface 608 and the base-locking slider fixing block inclined surface 610 are matched and connected.

[0052] The base slider device 6 achieves fastening by engaging the base slider 602 with the notch 401 of the hardware insert guide block, thus tightly securing the hardware insert guide block 4.

[0053] The rear mold core 8 is provided with an installation groove that is adapted to the hardware insert 2 and the hardware insert guide block 4. The installation groove is located on the cavity side of the rear mold core 8 used for molding the product. The shape and size of the installation groove match the shape of the hardware insert 2 and the hardware insert guide block 4. When the hardware insert 2 and the hardware insert guide block 4 are installed in the installation groove, their top surfaces are flush with the cavity surface of the rear mold core 8 to ensure that the plastic material can evenly wrap the hardware 1 during injection molding. The front end face of the snap-on slider 602 is designed with a bevel.

[0054] The working principle and steps of this utility model are as follows:

[0055] 1. When preparing to manufacture a product, first insert the hardware part 1 and the hardware part guide block 4 into the hardware part insert 2 outside the molding machine and wait for the robot to take them away. Then, open the mold to separate the front and rear molds. At this time, the robot outside the molding machine puts the hardware part insert 2 containing the hardware part 1 and the hardware part guide block 4 into the reserved position of the rear mold core 8 outside the mold opening and closing movement area. Then, close the mold and perform injection molding to form the product.

[0056] 2. Then, the mold is split. The front and rear molds are opened, and the front and rear ejector plates 7 are pushed forward. The other ejector pins on the ejector plates begin to contact the product. At this time, the hardware insert ejector pins 3 and hardware insert guide block ejector pins 5 located on the front and rear ejector plates 7 do not simultaneously contact the bottom of the hardware insert 2 and the bottom of the hardware insert guide block 4 due to their slightly shorter design.

[0057] 3. When the front and rear ejector plates 7 further push and actuate the product, the hardware insert ejector pin 3 and the hardware insert guide block ejector pin 5 will contact the bottom of the hardware insert 2 and the bottom of the hardware insert guide block 4. Their position design ensures that they do not contact the hardware insert 2 and the hardware insert guide block 4 in the initial stage of ejection. When the front and rear ejector plates 7 push, other ejector pins contact and actuate the product first. After the front and rear ejector plates 7 have moved a certain distance, the hardware insert ejector pin 3 and the hardware insert guide block ejector pin 5 will start to actuate the hardware insert 2 and the hardware insert guide block 4.

[0058] At this time, the front and rear ejector plates 7 continue to push forward. Due to the design of the notch 401 of the hardware insert guide block 4, it cooperates with the snap-on slider 602 in the snap-on slider device 6 to achieve snap-on. When the front and rear ejector plates 7 are pushed to a specific position, the snap-on slider fixing block 609 fixed on the front and rear ejector plates 7 will move in the snap-on slider fixing block through hole 607 in the snap-on slider housing 601 due to the push of the front and rear ejector plates 7. At this time, the inclined surface 608 of the snap-on slider fixing block through hole will contact the inclined surface 610 of the snap-on slider fixing block. The two have a mutually cooperating inclined surface structure at the contact position. When the front and rear ejector plates 7 continue to push, the snap-on slider fixing block 609 pushes open the entire snap-on slider housing 601 through the inclined surface structure and compresses the snap-on slider device spring 606.

[0059] Because the base slider 602 has a base slider hole 603 with a certain range of movement (horizontal sliding stroke) in the middle, and the base slider fixing bolt 604, which is fixed to the base slider housing 601, passes through the base slider hole 603, when the entire base slider housing 601 moves, the base slider device spring 606 pushes against the bottom of the base slider 602. Since the base slider fixing bolt 604 is fixed to the base slider housing 601, the base slider fixing bolt 604 will be stuck on the bottom side of the base slider hole 603, thus driving the base slider. 602 disengages from the notch 401 of the hardware insert guide block, freeing the hardware insert guide block 4 from restriction. The hardware insert ejector pin 3 and the hardware insert guide block ejector pin 5 can also eject the hardware insert 2 and the hardware insert guide block 4, allowing the product, hardware insert 2, and hardware insert guide block 4 to detach from the rear mold core 8. Then, the robot arm will remove the product, hardware insert 2, and hardware insert guide block 4, and then place another set of hardware insert 2, which has been fitted with hardware 1 and hardware insert guide block 4, into the position of the rear mold core 8 for mold closing.

[0060] 4. When the front and rear ejector plate 7 retracts until the inclined surface 610 of the base slider fixing block no longer contacts the inclined surface 608 of the through hole of the base slider fixing block, the reset mechanism of the base slider device 6 will be activated. The spring 606 of the base slider device will push open the entire base slider device 6, allowing the base slider device 6 to return to its original position. The hardware insert guide block 4 also retracts accordingly. The top of the hardware insert guide block 4 contacts the base slider 602 first. Due to the inclined surface design of the front end of the base slider 602, the hardware insert guide block 4... During the movement of block 4, the base slider 602 will first move inward to compress the base slider spring 605. When it reaches the position of the hardware insert guide block notch 401, the base slider spring 605 will pop out the base slider 602, so that the base slider 602 will quickly return to the initial position of engaging the hardware insert guide block 4, ensuring the continuity of the mold action. At this time, the front and rear ejector plates 7 continue to retract to their original positions, the front and rear molds merge, the injection molding operation of this product ends, and the injection molding operation cycle of the next product begins.

[0061] The above-described embodiments of this utility model primarily improve its adaptability and automation. The assembly of hardware parts and inserts is completed outside the mold. After injection molding, the ejector plate pushes the ejector pins to move the product, and the short ejector pins eject the inserts with a delay. The retaining block pushes open the retaining block, releasing its engagement with the insert guide block. The short ejector pin then ejects the insert and the guide block, disengaging them from the rear mold core. A robotic arm removes the product and the old insert, inserts the new insert with pre-assembled hardware into the rear mold core, and the retaining block re-engages, completing the cyclic operation. Therefore, through various design improvements, this utility model can achieve pre-assembly, ejection, and automated part replacement by a robotic arm, shortening the molding cycle, improving product yield, and is widely applicable to the efficient insert molding of hardware and plastics.

[0062] The above are merely specific embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any substitutions and improvements made without departing from the concept of this utility model shall fall within the scope of protection of this utility model.
