Description

Technical Field

[0001] The invention relates to the technical field of engraving dies, in particular to an engraving die with an anti-dislocation limiting structure. Background Art

[0002] In today's engraving industry, the quality and precision of engraving molds are key factors affecting the quality of engraved products. With the continuous development of science and technology and the increasing market requirements for high-precision and high-quality engraving products, traditional engraving molds have exposed many problems in practical applications, which provides a background for improvement and innovation for the engraving mold with an anti-dislocation limit structure of the present invention. In the mold closing operation of traditional engraving molds, the misalignment problem between the upper and lower molds is a difficult problem that needs to be solved urgently. During the frequent opening and closing of the mold, due to the influence of mechanical vibration, installation errors, mold wear and other factors, the upper and lower molds are prone to relative position deviation when closing the mold. This misalignment phenomenon will directly lead to deviations in the pattern or shape on the engraving work surface. For example, in a fine relief engraving mold, even a slight misalignment may cause the engraved pattern lines to be distorted and the contours to be blurred, seriously damaging the artistic beauty and precision of the engraving work. Moreover, long-term misalignment will not only make the engraved finished product The mold will be defective or waste, which will increase production costs and damage the mold structure itself. The key matching parts of the mold may accelerate wear due to abnormal force caused by misalignment, shorten the service life of the mold, and increase the frequency and cost of mold replacement. At the same time, the precise control of the relative position of the upper and lower molds during mold closing is also one of the challenges faced by traditional engraving molds. Traditional positioning methods are often difficult to meet the requirements of high-precision positioning when facing complex processing environments and constantly changing processing parameters. During the mold closing process, due to the lack of effective precise positioning and guiding mechanisms, the upper and lower molds cannot be accurately aligned according to the design requirements. Especially in batch engraving production that requires high repeatability, this problem of insufficient position accuracy will lead to large individual differences between engraved products and cannot guarantee the stability of product quality. This is unacceptable in some industrial engraving fields with extremely high precision requirements, such as engraving molds for aircraft engine blades and high-end jewelry molds. In addition, traditional engraving molds lack an effective position detection mechanism. During the mold closing process, the operator cannot obtain the information on the relative displacement of the upper and lower molds in time. Without accurate position detection, on the one hand, it is impossible to monitor the status of the mold during the closing process in real time, and it is difficult to detect potential misalignment problems in time. On the other hand, it is impossible to determine whether other related mechanisms in the mold are working normally. For example, if the limit mechanism fails for some reason and cannot be detected in time, the mold may accumulate a large number of errors in continuous operation, eventually leading to serious engraving quality problems. Moreover, after a mold fails, due to the lack of previous position detection data, it is difficult for maintenance personnel to accurately determine the cause and location of the failure, which increases the difficulty and time cost of maintenance.

[0023] Compared with the prior art, the invention has the following beneficial effects: the engraving die with anti-dislocation limiting structure: 1. By setting a contact limit mechanism, the driving force generated by the dislocation when the lower mold and the upper mold are closed is used to limit the dislocated upper mold. When there is a trend of dislocation, the toothed ring rod on the lower surface of the upper mold will interact with the driving gear inside the side surface of the lower mold. Due to the special design of the toothed ring rod, the toothed ring rod can accurately match the driving gear when the position is offset. This design makes it possible for the driving gear to drive the displacement rod under the action of the toothed ring rod during the mold closing process, and then push the limit baffle through the support rod to effectively support the upper mold that may be dislocated, thereby ensuring that the upper mold and the lower mold cannot be closed when they are dislocated, and avoiding damage to the upper mold and the lower mold due to dislocation; 2. The pressure guiding mechanism provides precise position adjustment for mold closing. The support columns, piston rods and positioning blocks arranged on the lower end surfaces of the four corners of the lower mold work together with the piston block and the connecting pipe on the upper surface of the lower mold. When the mold is closed, the pressure between the upper and lower molds is transmitted to the piston rod through the piston block under the action of the connecting pipe. Since the support columns and the piston rod are connected by sliding friction, and the piston block and the lower mold are connected by sliding friction and spring, this structure can adjust the position of the upper mold according to the mold closing pressure when the mold is closed, so that the upper and lower molds can be accurately positioned and guided during the mold closing process, effectively eliminating the position deviation caused by installation errors, mold deformation and other factors, ensuring that the relative position of the mold is always kept within a high-precision range during the entire processing process, which is conducive to improving the quality stability and consistency of the engraved products; 3. Through the cooperation of components such as the sliding groove, positioning block, sliding rod, functional gear rod, detection gear, reset plate, mounting plate, push switch and detection rod, during the mold closing process, the effectiveness of the push switch is monitored by utilizing the pressure rotation of the detection rod. After the lower mold and the upper mold are closed, the position accuracy of the lower mold and the upper mold is detected by whether the detection rod is rotated and disengaged and the press switch is triggered, thereby ensuring that long-term misalignment processing will not be caused by undetected detection failure.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 8 The present invention provides a technical solution: a carving mold with an anti-dislocation limiting structure.

[0028] Embodiment 1: This embodiment discloses a lower mold 1, an upper mold 2 is arranged above the lower mold 1, and a contact limiting mechanism is arranged below the upper mold 2, and the driving force generated by the dislocation when the lower mold 1 and the upper mold 2 are closed is used to limit the dislocated upper mold 2; The contact limiting mechanism comprises: a gear ring rod 3, which is fixedly arranged on the lower surface of the upper mold 2, a rotating driving gear 4 is installed inside the side surface of the lower mold 1, and one end of the rotating shaft of the driving gear 4 is fixedly connected with a displacement rod 5, a sliding support rod 6 is installed inside the outer surface of the lower mold 1, one end of the support rod 6 penetrates the outer surface of the lower mold 1, and a support plate 7 is fixedly arranged on the outer surface of the end of the lower mold 1 penetrated by the support rod 6, and a rotating limiting baffle 8 is installed on the outer surface of the lower mold 1 above the support plate 7; Both ends of the longitudinal section of the gear ring rod 3 are isosceles trapezoids, and the cross section of the gear ring rod 3 is a hexagonal design, and the vertical projection of the gear ring rod 3 does not overlap with the vertical projection of the driving gear 4; The driving gear 4 and the displacement rod 5 are concentrically arranged, and the displacement rod 5 and the support rod 6 are threadedly connected, and one end of the support rod 6 that passes through the outer surface of the lower mold 1 is directly opposite to the lower end of the limit baffle 8; When the relative position between the lower mold 1 and the upper mold 2 is offset during the mold closing process, the gear ring rod 3 is meshed with the driving gear 4 due to the offset. The gear ring rod 3 drives the driving gear 4 to rotate as the upper mold 2 moves downward. The driving gear 4 drives the support rod 6 to slide to the outside of the lower mold 1 through the threaded connection between the displacement rod 5 and the support rod 6. The support rod 6 slides out of the lower mold 1 and squeezes the lower end of the limit baffle 8 to rotate the limit baffle 8. The upper end of the limit baffle 8 turns to between the lower mold 1 and the upper mold 2 until the lower end of the limit baffle 8 rotates and fits with the upper end of the support plate 7. At this time, the lower end of the upper mold 2 contacts the upper end of the limit baffle 8. The limit baffle 8 supports the upper mold 2 through the upper end under the support of the support plate 7, so that the dislocated upper mold 2 cannot be closed with the lower mold 1.

[0029] Embodiment 2: Based on Embodiment 1, this embodiment discloses that the outer surfaces of the lower mold 1 and the upper mold 2 are provided with a pressure guiding mechanism, and the relative position between the lower mold 1 and the upper mold 2 is accurately positioned and guided by the pressure when the lower mold 1 and the upper mold 2 are closed; The pressure guiding mechanism comprises: a support column 9, which is fixedly arranged on the lower end surface of the four corners of the lower die 1, and a sliding piston rod 10 is installed on the upper end of the support column 9, and a positioning block 11 is fixedly arranged on the upper end of the piston rod 10, and a sliding piston block 12 is installed on the upper surface of the lower die 1, and a connecting pipe 13 is provided between the cavity of the lower die 1 where the piston block 12 is located and the cavity of the lower die 1 where the piston rod 10 is located; The support column 9 and the piston rod 10 are connected by sliding friction, the piston block 12 and the lower die 1 are connected by sliding friction, and a spring is connected between the piston block 12 and the lower die 1; When the lower mold 1 and the upper mold 2 are closed, the four corners of the upper mold 2 are in contact with the four positioning blocks 11 respectively, and the positioning blocks 11 are pressed downward until the lower surface of the upper mold 2 squeezes the piston block 12. The piston block 12 applies pressure to the piston rod 10 at the upper end of the support column 9 through the connecting pipe 13, so that the piston rod 10 drives the positioning block 11 to apply a lateral thrust to the upper mold 2, so that the upper mold 2 can be positioned and supported with the support of the positioning block 11 when lateral displacement occurs.

[0030] Embodiment 3: Based on Embodiment 1 and Embodiment 2, this embodiment discloses that the outer surfaces of the lower mold 1 and the upper mold 2 are provided with a position detection mechanism, and the relative displacement during the clamping process of the lower mold 1 and the upper mold 2 is respectively used to detect the effectiveness of the position detection mechanism itself and the relative position of the lower mold 1 and the upper mold 2; The position detection mechanism includes: a sliding groove 14, the sliding groove 14 is opened on the outer surface of the upper end of the lower mold 1, and a stopper 15 is fixedly arranged on the upper surface of the lower mold 1, a sliding sliding rod 16 is installed on the upper surface of the lower mold 1, and one end of the sliding rod 16 is fixedly connected to a functional gear rod 17, and an electric push rod 18 is installed on the side surface of one end of the functional gear rod 17, a rotating detection gear 19 is installed on the side surface of the upper mold 2, and a reset plate 20 is fixedly arranged on the outer surface of the detection gear 19, a mounting plate 21 is fixedly arranged on the side surface of the detection gear 19, and a press switch 22 is fixedly arranged on the lower end side surface of the mounting plate 21, a rotating detection rod 23 is installed on the outer surface of the detection gear 19, and the detection rod 23 is inclined toward the mounting plate 21, and a warning light 24 is fixedly installed on the upper surface of the upper mold 2; The sliding groove 14 is designed to be arc-shaped, and the upper end of the sliding groove 14 passes through the upper surface of the lower mold 1; The outer surface of the functional gear rod 17 facing the detection gear 19 is evenly provided with gear blocks, and the outer surface of the lower end of the functional gear rod 17 is in contact with the outer surface of the stopper 15, and the electric push rod 18 is threadedly connected to the lower mold 1; A spring is connected between the reset plate 20 and the lower die 1, and the reset plate 20 and the functional gear rod 17 are respectively located on both sides of the detection gear 19; The push switch 22 is arranged on the side of the mounting plate 21 facing the detection rod 23, and a spring is connected between the detection rod 23 and the mounting plate 21. The lower end of the detection rod 23 is L-shaped, and the lower end of the detection rod 23 is located inside the sliding groove 14. When the lower mold 1 and the upper mold 2 are finished being molded together, when the lower mold 1 and the upper mold 2 are molded together accurately, the detection gear 19 and the sliding groove 14 move to a concentric state, and the lower end of the detection rod 23 is opposite to the upper end of the sliding groove 14. During the process, the detection gear 19 rotates under the action of meshing with the functional gear rod 17. During the movement, the detection rod 23 first fits the upper surface of the lower mold 1 and rotates relative to the detection gear 19. When the lower mold 1 and the upper mold 2 are molded in place, the pressing switch 22 is triggered. When the lower mold 1 and the upper mold 2 are molded in place and there is no position deviation, the lower end of the detection rod 23 rotates and slides into the sliding groove 14 under the support of the spring between the mounting plate 21 to release the triggering of the pressing switch 22. The user judges whether the lower mold 1 and the upper mold 2 are molded accurately by observing whether the warning light 24 is off. When the relative positions of the lower mold 1 and the upper mold 2 are wrong, the lower end of the detection rod 23 cannot face the upper end of the sliding groove 14 due to the misalignment, so that the detection rod 23 cannot rotate. At this time, the detection rod 23 keeps triggering the press switch 22 so that the warning light 24 is continuously lit to remind the staff; When the die-cutting is completed, the electric push rod 18 drives the functional gear rod 17 to slide relative to the lower die 1 through the sliding rod 16 to disengage from the meshing with the detection gear 19 and the fit of the stop block 15, so that the detection gear 19 rotates and resets under the pull of the spring between the reset plate 20 and the upper die 2. At this time, the detection rod 23 rotates away from the sliding groove 14.
