Description

Technical Field

[0001] The utility model relates to the technical field of door leaf production equipment, and particularly relates to a compression mold for producing door leaves. Background Art

[0002] During the production of compression-molded door leaves, embedded bolts need to be added on one side of the door leaf for subsequent installation operations. During compression molding, the embedded bolts need to be fixed. The existing operation method is to insert a mandrel into the embedded bolt to prevent the embedded bolt from skewing or moving during compression molding. After the door leaf is processed, the mandrel needs to be withdrawn for recycling.

[0003] In the existing core-pulling operation, most of them use a telescopic electric cylinder to pull the mandrel to complete the pulling operation of the mandrel, and then realize the extraction operation of the mandrel. During installation, the telescopic electric cylinder is mostly perpendicular to one side of the mold, occupying a large area. Enough avoidance space needs to be reserved on the side wall of the mold, resulting in an increase in the occupied space of the entire equipment. Moreover, a guiding member for the mandrel needs to be added during the pulling of the telescopic electric cylinder, further increasing the space occupied by the equipment and making installation and maintenance inconvenient. Summary of the Utility Model

[0004] In order to solve the above problems, the embodiment of the utility model provides a compression mold for producing door leaves with a simple structure and capable of effectively reducing the length of the equipment.

[0005] The embodiment of the utility model specifically adopts the following technical solutions to achieve the above purpose: A compression mold for door leaf production, including an upper mold and a lower mold. A molding cavity for producing door leaves is formed between the upper mold and the lower mold. One side of the molding cavity is provided with a mandrel for fixing the embedded bolt, and an external part of the upper mold is provided with a core-pulling structure for extracting the mandrel.

[0006] As a further improvement of the above technical solution:

[0007] The core-pulling structure includes a protective shell arranged on the outer side wall of the upper mold. A guiding block is slidably installed in the protective shell. A guiding slope is arranged on the upper part of the guiding block. A slider connected to the mandrel is arranged on the guiding slope. One end of the protective shell is provided with a driving source for driving the guiding block to move.

[0008] Guiding ridges are arranged on both sides of the guiding block, and guiding grooves corresponding to the positions of the guiding ridges are arranged on the inner side wall of the protective shell.

[0009] A T-shaped groove is arranged on the guiding slope, and a positioning block that cooperates with the T-shaped groove is arranged on the lower part of the slider.

[0010] An insert for positioning the position of the door leaf is provided inside the upper mold, and a guiding channel corresponding to the position of the core shaft is provided on the insert.

[0011] Both the core-pulling structure and the insert are detachably connected to the upper mold.

[0012] The beneficial effects of the embodiment of the present utility model are as follows: The die pressing mold for door leaf production includes an upper mold and a lower mold. A forming cavity for manufacturing the door leaf is formed between the upper mold and the lower mold. A core shaft for fixing the embedded bolt is provided on one side of the forming cavity. An external core-pulling structure for extracting the core shaft is provided on the upper mold. Compared with the existing vertically installed core-pulling equipment, the telescopic end of the core-pulling structure in this new type is designed to be parallel to the long side of the door leaf. The telescopic operation of the core shaft is achieved through the design of the guiding slope, and the transmission is more stable, reducing the damage to the core shaft during the core-pulling process. Moreover, the telescopic direction of the electric push rod is changed through the guiding slope, reducing the width of the die pressing mold after the core-pulling structure is installed, and thus reducing the area occupied by the entire equipment.

[0021] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0022] As Figure 1-7 shown, the compression molding die for producing door leaves in this embodiment includes an upper die 1 and a lower die 2. A molding cavity 3 for manufacturing door leaves is formed between the upper die 1 and the lower die 2. A mandrel 4 for fixing the embedded bolt is provided on one side of the molding cavity 3. An ejection structure 5 for extracting the mandrel 4 is arranged outside the upper die 1. The design of the ejection structure 5 can extract the mandrel 4 after the door leaf is manufactured, and the extracted mandrel 4 can be reused. Using the ejection structure 5 can quickly complete the ejection operation. Compared with the traditional method of using an electric push rod for pulling, this ejection device is more stable during operation, will not damage the mandrel 4, and the horizontally installed ejection device can make the floor area of the device smaller.

[0023] The ejection structure 5 includes a protective housing 6 installed on the outer side wall of the upper die 1. A guiding block 7 is slidably installed inside the protective housing 6. The guiding block 7 slides along the length direction of the door leaf. A guiding slope 8 is provided on the upper part of the guiding block 7. A slider 9 connected to the mandrel 4 is arranged on the guiding slope 8. A driving source 10 for driving the guiding block 7 to move is provided at one end of the protective housing 6. The driving source 10 uses an electric push rod. The telescopic movement of the electric push rod drives the guiding block 7 to slide. By cooperating the guiding slope 7 with the slider 9, the height of the slider 9 inside the protective housing 6 is changed during the sliding process to complete the extraction and pulling of the mandrel 4.

[0024] Guiding ridges 11 are provided on both sides of the guiding block 7. Guiding grooves 12 corresponding to the positions of the guiding ridges 11 are provided on the inner side wall of the protective housing 6. The cooperation of the guiding ridges 11 and the guiding grooves 12 can improve the stability of the guiding block 7 during sliding.

[0025] A T-shaped groove 13 is provided on the guiding slope 8. A positioning block that cooperates with the T-shaped groove 13 is arranged at the lower part of the slider 9. The slider 13 slides along the guiding slope 8, and the mandrel 4 is extracted when it slides to the lowest end of the guiding slope 8.

[0026] An insert 14 for positioning the position of the door leaf is provided inside the upper die 1. A guiding channel 15 corresponding to the position of the mandrel 4 is provided on the insert 14. The insert 14 is located on the inner side wall of the upper die 1, which plays a role in protection and guiding when the mandrel 4 is extracted, avoiding the skewing of the mandrel 4 during extraction.

[0027] The core-pulling structure 5 and the insert 14 are both detachably connected to the upper die 1 by bolts. When machining the left door leaf, the core-pulling structure 5 and the insert 14 are installed on the left side of the upper die 1. When producing the right door leaf, they are disassembled and installed on the right side of the upper die 1. The structure is simple and convenient to disassemble, and can also complete the machining of the left and right door leaves, reducing the investment cost of production equipment.
