Description

Technical Field

[0001] This utility model belongs to the field of explosives manufacturing technology, and relates to a propellant pressing mold, specifically an automatic mold disassembly mechanism. Background Technology

[0002] Ammunition (explosives) needs to be molded before use. The applicant has designed a mold comprising a lower mold, a middle mold, and an upper mold. The lower mold has a lower punch on its bottom surface and at least three guide posts distributed in different directions near its outer edge. The middle mold has at least one mold sleeve, into which the lower punch extends to form a sealed charging cavity. The upper mold has an upper punch matching the number of mold sleeves.

[0028] like Figures 1 to 3 As shown, this embodiment provides an automatic mold dismantling mechanism, which includes: a frame 1, a mold receiving seat 2, a positioning lifting plate 3, a sliding frame 4, a mold splitting receiving seat 5, and a clamping assembly 6;

[0029] The frame 1 has a short slide rail 101 at its bottom and a sliding block 401 at its bottom. The sliding block 401 is mounted on the short slide rail 101 and is slidably connected to it. It slides along the short slide rail under the action of the drive mechanism. The upper end of the frame 1 has multiple rollers 102 arranged side by side on the inner side of the two uprights. The lower mold 91 of the mold 9 is mounted on the rollers. The upper end of the frame 1 has a sliding drive assembly 7 on the two uprights. The sliding drive assembly 7 is used to drive the mold 9 on the rollers to move.

[0030] The mold receiving seat 2 is located near the end of the frame 1. The mold is conveyed in a direction perpendicular to the frame 1 and enters the mold receiving seat 2. The bottom of the mold receiving seat 2 is provided with a first lifting cylinder (not shown). The mold receiving seat 2 is raised or lowered by the first lifting cylinder. When the mold 9 enters the mold receiving seat 2, the mold receiving seat 2 lowers, so that the lower mold 91 of the mold contacts the roller 102, and the mold is driven to move towards the sliding frame 4 by the sliding drive assembly 7.

[0031] A positioning lifting plate 3 is provided at the initial position of the sliding frame 4. The positioning lifting plate 3 is located between opposite rollers 102. A lifting cylinder (unmarked) is provided at the bottom of the positioning lifting plate 3. The lifting cylinder lifts the mold so that the lower mold 91 and the middle mold 92 contact the lower positioning block 402 and the middle positioning block 403 set on the sliding frame 4. A mold splitting support 5 is provided away from the initial position of the sliding frame 4, that is, near the end of the short slide rail. The mold splitting support 5 is located between opposite rollers 102. A second lifting cylinder (unmarked) is provided at the bottom of the mold splitting support 5. The second lifting cylinder controls the mold splitting support 5 to rise or fall, receive the removed upper mold 93 or middle mold 92, and make the removed upper mold or middle mold contact the rollers 102. Then, the upper mold or middle mold is sent to the cleaning process position in sequence by the sliding drive assembly 7.

[0032] The top of the sliding frame 4 is provided with a clamping drive mechanism 8, which is used to drive the clamping assembly 6 to perform lifting and lowering actions.

[0033] The clamping assembly 6 is used to clamp the upper mold or the middle mold, and under the action of the clamping drive mechanism, the upper mold or the middle mold is removed from the guide post of the mold.

[0034] Furthermore, such as Figure 1 , Figure 2 As shown, in this embodiment, the sliding drive assembly 7 includes a long slide rail (not shown) fixed on the stand, a long slider 701 slidably connected to the long slide rail, a long profile 702 mounted on the long slider, a horizontal plate 703 for connecting two long profiles, a drive mechanism 704 fixed to the end of the frame 1 for driving the horizontal plate 703 to reciprocate, positioning clamps 705 spaced apart on the long profile 702, and a small cylinder 706 for driving the jaws of the positioning clamps. The distance between two adjacent positioning clamps 705 is adapted to the length of the mold. When the jaws 7051 of the positioning clamps 705 extend, the mold is located between two adjacent jaws 7051 and moves synchronously with the positioning clamps. When the jaws of the positioning clamps retract, the positioning clamps 705 and the mold can move relative to each other.

[0035] Furthermore, such as Figure 3As shown, in this embodiment, the clamping assembly 6 includes a base plate 601, two parallel slide rails 602 mounted on the base plate, a left slider 603 and a right slider 604 disposed at both ends of the slide rails, a left connecting plate 605 for connecting the two left sliders, a right connecting plate 606 for connecting the two right sliders, a bidirectional synchronous drive mechanism (not labeled) connected to the left and right connecting plates, an L-shaped left clamping block 607 mounted on the left connecting plate, an L-shaped right clamping block 608 mounted on the right connecting plate, a clamping plate 609 disposed between the L-shaped left and right clamping blocks, a movable plate 610 connected to the clamping plate, and a small lifting cylinder 611 mounted on the base plate for driving the movable plate; the clamping assembly 6 functions in clamping the drive mechanism 8. The L-shaped left and right clamping blocks move downwards, positioning the upper or middle mold between them. At this point, the bidirectional synchronous drive mechanism is activated, causing the L-shaped left and right clamping blocks to move towards each other, clamping the upper or middle mold. Then, the clamping drive mechanism controls the clamping assembly to move upwards, bringing the bottom surface of the upper or middle mold into contact with the bottom surfaces of the L-shaped left and right clamping blocks. Next, the small lifting cylinder is controlled to move, bringing the clamping plate into contact with the top surface of the upper or middle mold. Under the combined action of the L-shaped left and right clamping blocks and the clamping plate, the upper or middle mold is positioned and tightened. Then, the clamping assembly is controlled to move upwards again, disassembling the upper or middle mold. Finally, the sliding frame moves, transporting the disassembled upper or middle mold to the mold splitting support for resetting.

[0036] Furthermore, in this embodiment, the positioning lifting plate 3 is provided with a positioning pin (not shown) that cooperates with the positioning hole on the lower mold to achieve positioning.

[0037] Furthermore, in this embodiment, the sliding frame 4 is provided with a first guide rod 404, and the base plate 601 of the clamping assembly 6 is provided with a first guide sleeve 6011 adapted to the first guide rod.

[0038] Furthermore, in this embodiment, the substrate 601 is provided with a second guide rod 6012, the left connecting plate and the right connecting plate are provided with an elongated clearance hole (not shown) at a position opposite to the second guide rod, and the clamping plate 609 is provided with a second guide sleeve (not marked) adapted to the second guide rod.

[0039] Furthermore, in this embodiment, the clamping plate 609 is provided with a positioning pin (not shown) that cooperates with the positioning hole on the upper mold to achieve positioning.

[0040] Furthermore, in this embodiment, the mold splitting support 5 and the clamping plate 609 are provided with clearance holes (unmarked) at positions opposite to the mold sleeve of the middle mold. In the mold schematic diagram provided in this embodiment, the middle mold 92 is provided with a mold sleeve, which is only used for illustration. The specific number of mold sleeves on the mold can be adjusted according to the actual situation, for example, it can also be four.

[0041] Furthermore, in this embodiment, the middle positioning block 403 is a telescopic positioning block driven by a cylinder (not marked). When the upper mold is disassembled, the telescopic positioning block extends to limit the middle mold. When the middle mold is disassembled, the telescopic positioning block retracts and no longer limits the middle mold.

[0042] The above describes specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
