Description

Technical Field

[0001] This utility model belongs to the field of template locking technology, and more specifically, it relates to an adjustable hollow locking device. Background Technology

[0002] In molding processes such as injection molding and die casting, the mold clamping device is a key component ensuring the normal operation of the mold. With the increasing demands for mold adaptability in the manufacturing industry, an adjustable hollow mold clamping device has emerged. Existing adjustable hollow mold clamping devices mainly consist of a tail plate, head plate, second plate, hydraulic mechanism, adjustment mechanism, and mechanical hinge mechanism. The tail plate, as a basic component, is used to install and fix the hydraulic mechanism, adjustment mechanism, and Green Column. A pair of molds are fixed between the head plate and the second plate respectively. The mechanical hinge mechanism, driven by the hydraulic mechanism, extends, moving the second plate to complete the mold clamping. The Green Column provides guidance for the movement of the second plate. The adjustment mechanism, through the coordinated operation of a servo motor and a lead screw and nut pair, can control the displacement of the second plate along the axial direction of the Green Column, achieving stepless adjustment of the distance between the head plate and the second plate, adapting to molds of different thicknesses. Furthermore, the head plate adopts a hollow design, facilitating connection with the high-pressure injection mechanism.

[0003] This utility model, with application number CN201820532292.7, provides a mold-locking mechanism, relating to the field of injection molding machines. The mold-locking mechanism includes: a head plate; multiple tie rods, with the head plate fixedly mounted at one end of the tie rods; a movable plate, with the tie rods passing through and slidably connected to the movable plate, defining a space for clamping the mold between the movable plate and the head plate; a tail plate, fixedly mounted at the other end of the tie rods; a mechanical hinge assembly, hinged to the tail plate; and a hydraulic cylinder, fixedly mounted at the end of the tail plate away from the movable plate, with the piston rod of the hydraulic cylinder passing through the tail plate and connected to the mechanical hinge assembly, the hydraulic cylinder driving the movable plate closer to or away from the head plate. This mold-locking mechanism has a reasonable structure, strong practicality, convenient mold clamping, and long service life.

[0004] Based on the above, most existing adjustable hollow mold clamping devices achieve limiting and fixing through the cooperation of the clamping block on the back of the mold and the clamping grooves of the head plate and second plate. After long-term use, problems such as wear of the clamping grooves and accumulation of impurities may cause the clamping block to not fully fit the bottom of the groove. When there is a gap between the clamping block and the groove, the two halves of the mold are prone to misalignment during the locking process, affecting the molding accuracy of the product. In addition, under high-pressure melt injection process, the mold and the head plate and second plate will experience a sudden temperature rise due to heat accumulation. If the exposed high-temperature components do not have effective protection, they can easily cause safety accidents such as burns to operators. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an adjustable hollow mold-locking device. This addresses the issue that most existing adjustable hollow mold-locking devices achieve positioning and fixation through the cooperation of a locking block on the back of the mold with the slots on the head plate and second plate. However, after prolonged use, wear and tear on the slots and accumulation of impurities can prevent the locking block from fully engaging with the bottom of the slots. When a gap exists between the locking block and the slot, misalignment can easily occur between the two halves of the mold during locking, affecting the product molding accuracy. Furthermore, under high-pressure melt injection molding, the mold, head plate, and second plate experience a rapid temperature rise due to heat accumulation. If these exposed high-temperature components lack effective protection, they can easily cause burns and other safety accidents for operators.

[0006] The purpose and effect of this adjustable hollow mold-locking device are achieved by the following specific technical means:

[0007] An adjustable hollow mold-locking device includes a mounting plate, a tail plate, a hydraulic drive mechanism, a mechanical hinge mechanism, a Grinding post, an adjustment mechanism, a head plate, a second plate, a protective shell, a warning component, and a protective component. The tail plate is fixedly mounted on the upper part of the mounting plate; the hydraulic drive mechanism is mounted on one side of the tail plate; the mechanical hinge mechanism is mounted on one end of the hydraulic drive mechanism; the Grinding post is mounted on one side of the tail plate; the adjustment mechanism is located on one side of the tail plate; the head plate is bolted to the upper part of the mounting plate; the second plate is slidably connected to the outside of the Grinding post and hinged to one end of the mechanical hinge mechanism; the protective shell is slidably connected to the outside of the head plate; the warning component is located inside the head plate and the second plate; and the protective component is located on the upper part of the mounting plate.

[0008] Furthermore, the prompting component includes: a forming template, a snap-fit ​​block, and a snap-fit ​​groove. The forming template is provided in a pair, which are snap-fitted into the inner sides of the head plate and the second plate, respectively. The snap-fit ​​block is provided in two pairs, which are fixedly connected to the outer sides of the pair of forming templates, respectively. The snap-fit ​​groove is provided in two pairs, which are opened into the inner sides of the head plate and the second plate, respectively.

[0009] Furthermore, the prompting component also includes: a trigger switch, wherein two pairs of trigger switches are provided, and the two pairs of trigger switches are respectively fixedly installed at the bottom of two pairs of card slots.

[0010] Furthermore, the indicator component also includes: a first indicator light and a second indicator light, the first indicator light being fixedly installed on the front side of the protective housing; the second indicator light being fixedly installed on the front side of the protective housing, and the first indicator light, the second indicator light, the trigger switch, and the microcontroller mechanism disposed inside the mounting plate being connected together by a wiring harness to form a switching circuit.

[0011] Furthermore, the protective assembly includes: a driven gear and a drive rack. The driven gear is provided in two sets, which are rotatably connected to the left and right sides of the head plate. The drive rack is provided in two sets, which are fixedly connected to one side of the second plate and slidably connected to the left and right sides of the head plate. The drive rack and the driven gear mesh with each other.

[0012] Furthermore, the protective assembly also includes a driven rack, wherein two sets of driven racks are provided, the two sets of driven racks are fixedly installed on both sides inside the protective housing, the two sets of driven racks slide inside the head plate and the second plate, and the driven racks and driven gears mesh with each other.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] Firstly, this invention features a prompting component. Through the coordinated design of the locking block, locking slot, trigger switch, and indicator light, a dual detection and intelligent early warning mechanism for mold installation status is established. Compared to traditional mold-locking devices that rely on manual visual inspection of mold installation, this invention can accurately identify whether the locking block is fully engaged in the bottom of the locking slot, avoiding the risk of mold misalignment due to improper installation. When the mold is installed correctly, a green light illuminates and unlocks the mold-locking operation; conversely, if a potential installation hazard is detected, a red light alarms and a forced power cut-off occurs, significantly reducing the probability of production accidents caused by human negligence and greatly improving the accuracy of mold installation and the safety of equipment operation.

[0015] Secondly, this invention features a protective component. Through the meshing transmission of a drive rack and pinion, driven gear, and driven rack, the protective shell and mold-locking action are automated and coordinated. Unlike existing devices that require manual operation of the protective components or lack a protective structure, this device can simultaneously drive the protective shell to automatically slide to the periphery of the molding template during the second platen movement and mold-locking process, forming a physical isolation barrier. This design effectively prevents operators from contacting the high-temperature mold and the surfaces of the head plate and second platen, while reducing the possibility of foreign objects entering the mold's working area. This ensures personnel safety, reduces the product defect rate caused by external interference, and improves the safety and stability of the production process.

[0016] This utility model has advantages such as installation status detection, safety protection, and ease of use, which greatly improves the accuracy of mold installation and the safety of equipment operation, and also enhances the safety and stability of the production process.

Detailed Implementation

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] Example 1:

[0026] As attached Figure 1 To be continued Figure 5 As shown:

[0027] This utility model provides an adjustable hollow mold-locking device, including a mounting plate 1, a tail plate 2, a hydraulic drive mechanism 3, a mechanical hinge mechanism 4, a Green column 5, an adjustment mechanism 6, a head plate 7, a second plate 8, a protective shell 9, and a warning component. The tail plate 2 is fixedly mounted on the upper part of the mounting plate 1; the hydraulic drive mechanism 3 is mounted on one side of the tail plate 2; the mechanical hinge mechanism 4 is mounted on one end of the hydraulic drive mechanism 3; the Green column 5 is mounted on one side of the tail plate 2; the adjustment mechanism 6 is located on one side of the tail plate 2; the head plate 7 is bolted to the upper part of the mounting plate 1; the second plate 8 is slidably connected to the outside of the Green column 5 and hinged to one end of the mechanical hinge mechanism 4; the protective shell 9 is slidably connected to the outside of the head plate 7; and the warning component is located inside the head plate 7 and the second plate 8.

[0028] The prompting component includes: a forming template 10, a snap-fit ​​block 1001, and a snap-fit ​​groove 11. A pair of forming templates 10 are provided, and the pair of forming templates 10 are snap-fitted into the inner sides of the head plate 7 and the second plate 8, respectively. Two pairs of snap-fit ​​blocks 1001 are provided, and the two pairs of snap-fit ​​blocks 1001 are fixedly connected to the outer sides of the pair of forming templates 10, respectively. Two pairs of snap-fit ​​grooves 11 are provided, and the two pairs of snap-fit ​​grooves 11 are respectively opened into the inner sides of the head plate 7 and the second plate 8.

[0029] The prompting component also includes: a trigger switch 12, of which two pairs of trigger switches 12 are provided, and the two pairs of trigger switches 12 are respectively fixedly installed at the bottom of the two pairs of card slots 11.

[0030] The prompting component also includes: a first prompt light 901 and a second prompt light 902. The first prompt light 901 is fixedly installed on the front side of the protective housing 9; the second prompt light 902 is fixedly installed on the front side of the protective housing 9. The first prompt light 901, the second prompt light 902, the trigger switch 12, and the microcontroller set inside the mounting plate 1 are connected together by a wiring harness to form a switching circuit.

[0031] The specific usage and function of this embodiment are as follows:

[0032] During the mold installation phase, the operator inserts a pair of molding templates 10 into the corresponding snap-fit ​​grooves 11 on the inner sides of the head plate 7 and the second plate 8 via the snap-fit ​​blocks 1001 on their outer sides, achieving rapid positioning and installation. This snap-fit ​​structure, in conjunction with the trigger switch 12, forms a dual detection mechanism: when the snap-fit ​​block 1001 is completely inserted into the bottom of the snap-fit ​​groove 11, the trigger switch 12 embedded in the bottom of the groove is triggered. At this time, the first indicator light 901 and the second indicator light 902 on the front side of the protective housing 9 simultaneously light up green, providing the operator with direct feedback on the mold installation being in place. Simultaneously, this signal is transmitted via wiring harness to the microcontroller mechanism within the mounting plate 1, unlocking the hydraulic drive mechanism 3's activation permission and allowing the device to perform the mold locking operation.

[0033] If the locking block 1001 fails to fully engage with the bottom of the locking slot 11 due to wear, impurity buildup, or improper installation, the corresponding trigger switch 12 will remain off, and the associated first indicator light 901 or second indicator light 902 will illuminate red. At this time, the microcontroller will immediately cut off the power to the device, forcibly terminating the subsequent mold-locking process, and will use the illuminated lights to prompt the operator to check and adjust the mold installation at the corresponding position.

[0034] In this embodiment, the micro-control mechanism controls the switching circuit, which is existing technology and will not be described in detail here.

[0035] Example 2:

[0036] Based on Example 1, such as Figures 1 to 5 As shown, it also includes: a protective component, which is disposed on the upper part of the mounting plate 1.

[0037] The protective components include: driven gears 701 and drive racks 801. Two sets of driven gears 701 are provided, and the two sets of driven gears 701 are rotatably connected to the left and right sides of the head plate 7. Two sets of drive racks 801 are provided, and the two sets of drive racks 801 are fixedly connected to one side of the second plate 8 and slidably connected to the left and right sides of the head plate 7. The drive racks 801 and driven gears 701 mesh with each other.

[0038] The protective assembly also includes a driven rack 903, which is provided in two sets. The two sets of driven racks 903 are fixedly installed on both sides inside the protective housing 9. The two sets of driven racks 903 slide inside the head plate 7 and the second plate 8. The driven racks 903 and the driven gear 701 mesh with each other.

[0039] The specific usage and function of this embodiment are as follows:

[0040] When the hydraulic drive mechanism 3 drives the hinge mechanism 4, causing the second platen 8 to move and perform mold locking, the movement of the second platen 8 causes the drive rack 801 to slide inside the head platen 7. The movement of the drive rack 801 causes the driven gear 701 to rotate, which in turn causes the driven rack 903 to move. The movement of the driven rack 903 causes the protective shell 9 to move. When the second platen 8 completes the mold locking action, the protective shell 9 precisely covers the periphery of the forming template 10, forming a physical isolation barrier. This effectively prevents operators from accidentally touching the high-temperature head platen 7, second platen 8, and forming template 10 during equipment operation.
