Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a bending forming mold with an arc-shaped guide groove. Background Technology

[0002] In the Christmas crafts manufacturing industry, the quality and efficiency of forming Christmas branches and leaves have a significant impact on the overall quality and market competitiveness of the products. With the continuous growth in market demand for Christmas crafts and consumers' increasingly higher requirements for product appearance and quality, the technical level of Christmas branch and leaf forming molds urgently needs improvement. In recent years, mold manufacturing technology has continuously developed, providing a technological foundation for the innovation of Christmas branch and leaf forming molds. Existing Christmas branch and leaf forming molds have some obvious defects in structure and function. Structurally, most molds lack a reasonable guide groove design, leading to inaccurate positioning of branches and leaves during the forming process, making them prone to displacement and affecting forming accuracy. Functionally, the pressure application devices of existing molds are not stable and precise enough, resulting in inconsistent bending and shaping effects of branches and leaves, and inconsistent product quality. Utility Model Content

[0003] The purpose of this invention is to provide a bending forming mold with an arc-shaped guide groove, so as to solve the problem mentioned in the background art that the existing Christmas tree branch forming mold lacks a reasonable guide groove design.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A bending forming mold with an arc-shaped guide groove includes a bending forming mold table for shaping Christmas branches and leaves, wherein a movable top seat is embedded at the center of the top surface of the bending forming mold table, and a hydraulic cylinder is installed in the middle of one side of the bending forming mold table.

[0006] The top surfaces of the movable top seat and the bending forming mold table are provided with several sets of uniformly and equidistantly arranged first arc-shaped guide grooves. The top surface of the bending forming mold table is provided with a lifting slide groove that is adapted to the cross-sectional size of the movable top seat and is slidably fitted. The two sides of the lifting slide groove are provided with second arc-shaped guide grooves that are the same number as the first arc-shaped guide grooves and are corresponding in position.

[0007] A pressure boosting top seat is vertically mounted on the top of the piston rod of the hydraulic cylinder, and a pressure boosting movable seat that is adapted to and plugged into the cross-sectional dimensions of the lifting slide is mounted on the bottom of the pressure boosting top seat.

[0008] The bottom of the movable top seat is vertically connected to a guide seat, and the bottom of the guide seat is equipped with several sets of plug rods. A return spring is wound around the outer wall of the plug rod.

[0009] Preferably, the first and second arc-shaped guide grooves have the same cross-sectional size and depth, ensuring more uniform stress distribution when the Christmas branches and leaves are bent and formed in the mold. Because guide grooves of the same specifications guarantee consistent bending conditions at all positions, they prevent excessive or insufficient localized stress caused by differences in guide groove design, thereby improving the consistency and quality stability of the branch and leaf forming process and resulting in a more regular appearance of the produced Christmas branches and leaves.

[0010] Preferably, the lifting slide has an inverted T-shaped cross-section, which enhances its stability and strength. During mold operation, the movable top seat slides within the lifting slide. This structure effectively prevents slide deformation, ensures smooth and accurate sliding of the movable top seat, and thus improves the overall working performance and service life of the mold.

[0011] Preferably, the movable top seat and the guide seat are integrally formed with an inverted T-shaped cross-section, which makes the movement of the movable top seat in the groove more precise, while enhancing the load-bearing capacity of the movable top seat and the guide seat, ensuring that they can withstand greater pressure without damage during the bending and forming process.

[0012] Preferably, the bottom of the lifting slide has insertion slots that are the same number and have the same cross-sectional dimensions as the insertion rods, and are designed for precise insertion. This precise fit between the insertion slots and the insertion rods ensures the accuracy of the movable top seat during the reset process. After the mold completes the bending and forming operation, the insertion rods can accurately insert into the insertion slots, allowing the movable top seat to quickly and accurately return to its initial position, improving the mold's working efficiency and ensuring consistency in each forming operation.

[0013] Preferably, the width and height of the pressure-boosting seat are the same, enabling the application of pressure evenly. This ensures that the pressure on each part of the Christmas tree branches and leaves is balanced during the bending and shaping process, avoiding inconsistent deformation caused by uneven pressure and further improving the shaping quality of the branches and leaves.

[0014] Preferably, the connection section between the guide seat and the plug-in rod is T-shaped, which enhances the connection strength between the guide seat and the plug-in rod. During mold operation, the plug-in rod needs to withstand a certain force to drive the guide seat and the movable top seat to reset. This connection structure effectively prevents the plug-in rod from separating from the guide seat, ensuring the reliability of the reset mechanism and enabling the mold to work stably and efficiently.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: In this bending forming mold with arc-shaped guide groove, the bending forming mold platform and its top surface first arc-shaped guide groove, together with the movable top seat and its first arc-shaped guide groove and the second arc-shaped guide groove on the lifting slide, can simultaneously shape and bend Christmas branches and leaves at multiple positions; by driving the piston rod of the hydraulic cylinder to press down the pressure boosting top seat and the pressure boosting movable seat, the branches and leaves can be further pressurized and shaped to ensure the shaping effect; through the guide seat, plug-in rod and return spring at the bottom of the movable top seat, the movable top seat can be automatically reset after shaping, which is convenient for the next shaping operation. The overall structure is reasonable and improves the bending forming efficiency and quality of Christmas branches and leaves. Attached Figure Description

[0026] Bending forming mold with curved guide groove, such as Figures 1-3 As shown, the device includes a bending forming mold platform 10 for shaping Christmas tree branches and leaves. A movable top seat 30 is embedded in the center of the top surface of the bending forming mold platform 10. A hydraulic cylinder 20 is installed in the middle of one side of the bending forming mold platform 10. The top surfaces of both the movable top seat 30 and the bending forming mold platform 10 are provided with several sets of uniformly spaced first arc-shaped guide grooves 11. A lifting slide groove 12, which is adapted to the cross-sectional dimensions of the movable top seat 30 and is slidably fitted, is installed in the middle of the top surface of the bending forming mold platform 10. The two sides of the lifting slide groove 12 are provided with second arc-shaped guide grooves 13, which are the same number and corresponding in position as the first arc-shaped guide grooves 11. A pressure boosting top seat 22 is vertically installed on the top of the piston rod 21 of the hydraulic cylinder 20. A pressure boosting movable seat 23, which is adapted to the cross-sectional dimensions of the lifting slide groove 12 and is plugged into the bottom of the pressure boosting top seat 22, is installed. The bottom of the movable top seat 30 is vertically... A guide seat 31 is directly connected to the bottom of the guide seat 31, and several sets of plug-in rods 32 are installed at the bottom of the guide seat 31. A return spring 33 is wound around the outer wall of the plug-in rod 32. Through the set bending forming mold table 10 and the first arc-shaped guide groove 11 on its top surface, in conjunction with the movable top seat 30 and the first arc-shaped guide groove 11 on it and the second arc-shaped guide groove 13 on the lifting slide 12, the Christmas tree branches and leaves can be bent and shaped in multiple positions at the same time. The piston rod 21 of the hydraulic cylinder 20 drives the pressure boosting top seat 22 and the pressure boosting movable seat 23 to press down, which can further pressurize and shape the branches and leaves to ensure the shaping effect. Through the guide seat 31, plug-in rods 32 and return spring 33 at the bottom of the movable top seat 30, the movable top seat 30 can be automatically reset after shaping, which is convenient for the next shaping operation. The overall structure is reasonable and improves the bending and shaping efficiency and quality of Christmas tree branches and leaves.

[0027] It is worth noting that the first arc-shaped guide groove 11 and the second arc-shaped guide groove 13 have the same cross-sectional size and depth, which makes the Christmas tree branches and leaves more evenly stressed and more consistent in shaping during the bending process, thus ensuring the stability of product quality.

[0028] Furthermore, the lifting slide 12 has an inverted T-shaped cross section, and the movable top seat 30 and the guide seat 31 are integrally formed with an inverted T-shaped cross section, which makes the sliding of the movable top seat 30 in the lifting slide 12 more stable, enhances the overall structural strength of the mold, and improves the service life of the mold.

[0029] Specifically, the bottom of the lifting slide 12 is provided with insertion slots 14, which are the same number as the insertion rods 32, have the same cross-sectional size, and are inserted into each other. This allows the insertion rods 32 to be accurately inserted into the insertion slots 14, ensuring the accuracy of the movable top seat 30 during the reset process and improving the working efficiency of the mold.

[0030] The pressure-boosting movable seat 23 and the movable top seat 30 have the same width and height, which allows the pressure-boosting movable seat 23 to fit tightly with the movable top seat 30 during the pressing process, applying uniform pressure to the Christmas tree branches and leaves, and further improving the shaping effect.

[0031] In addition, the connection section between the guide seat 31 and the plug rod 32 is T-shaped, which enhances the connection strength between the guide seat 31 and the plug rod 32, so that the plug rod 32 can better drive the guide seat 31 and the movable top seat 30 to reset when under force, thus ensuring the normal operation of the mold.

[0032] The working principle of this bending forming die with arc-shaped guide groove:

[0033] First, place the Christmas tree branches and leaves that need to be bent into shape in the first arc-shaped guide groove 11 on the top surface of the bending mold table 10 and the second arc-shaped guide groove 13 on the lifting slide 12 to ensure that the branches and leaves are in the correct position.

[0034] Next, the hydraulic cylinder 20 is activated, and the piston rod 21 of the hydraulic cylinder 20 extends downward, driving the pressure boosting top seat 22 and the pressure boosting movable seat 23 to move downward; the pressure boosting movable seat 23 is inserted into the lifting slide 12 and contacts the movable top seat 30, continuing to press down to bend and shape the branches and leaves;

[0035] After the shape is finalized, the piston rod 21 of the hydraulic cylinder 20 is retracted upward, driving the pressure boosting top seat 22 and the pressure boosting movable seat 23 to rise; at this time, the insertion rod 32 on the guide seat 31 at the bottom of the movable top seat 30 moves upward along the insertion groove 14 under the elastic force of the return spring 33, so that the movable top seat 30 is reset.

[0036] Finally, the operator removes the shaped Christmas tree branches from the first arc-shaped guide groove 11 and the second arc-shaped guide groove 13, completing one bending and shaping operation; by repeating this process, the Christmas tree branches can be bent and shaped efficiently and precisely.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
