Description

Technical Field

[0001] This utility model relates to the field of engine underbody protection plate production technology, specifically to an engine underbody protection plate forming device that enables automatic demolding. Background Technology

[0002] Existing car chassis typically have underbody protection plates installed to protect the engine. These plates are usually made of fiberglass, which is lightweight and has high strength. The production process of engine underbody protection plates requires stamping equipment and molds. However, based on existing molds, the underbody protection plates cannot be quickly ejected after stamping, resulting in inefficient removal and low work efficiency.

[0003] For example, Chinese patent CN202122697346.X discloses a mold for easy ejection in the production of engine underbody plates. It uses a rotating shaft to drive a cam to rotate, and the cam presses against a push rod, causing the push rod to rise and eject the underbody plate, thus enabling timely removal of the underbody plate. However, in this device, the ejection of the underbody plate is carried out manually through the rotating shaft, which is easily affected by human factors and still suffers from problems such as inability to remove it in a timely manner and low efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model proposes an engine underbody protection plate forming device that enables automatic demolding.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0006] An engine underbody protection plate forming device for automatic demolding includes a base, a top seat located above the base, a power mechanism disposed on the top seat, a connecting plate disposed at the bottom of the top seat and connected to the power mechanism, a lower template disposed on the base, and an upper template fixedly installed at the bottom of the connecting plate. A demolding lifting mechanism is disposed on the base and at the bottom of the lower template. Two sets of locking assemblies are disposed on the left and right sides of the demolding lifting mechanism. Two lifting rods are disposed on the bottom sides of the connecting plate, and the two lifting rods are located directly above the two sets of locking assemblies.

[0007] After the two lifting rods descend with the connecting plate, they are locked into the two sets of locking assemblies. When the mechanism is raised and reset, the two sets of locking assemblies drive the demolding lifting mechanism to lift out the engine bottom guard plate in the lower mold. After the demolding lifting mechanism reaches the lifting limit position, the two lifting rods disengage from the two sets of locking assemblies, and the demolding lifting mechanism resets.

[0008] The beneficial effects of this utility model are:

[0009] This utility model provides an engine underbody protection plate forming device for automatic demolding. Through the setting of a lifting rod, a locking assembly, and a demolding lifting mechanism, the lifting rod is engaged with the locking assembly after the connecting plate descends. When rising and resetting, the locking assembly drives the demolding lifting mechanism to lift the engine underbody protection plate out of the lower mold. The automatic demolding is achieved by using the return force after stamping as the driving source, and the removal is timely, which greatly improves the work efficiency. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figures 1 to 4As shown, an engine underbody protection plate forming device for automatic demolding includes a base 1, a top seat 2 located above the base 1, a power mechanism 3 mounted on the top seat 2, a connecting plate 4 located at the bottom of the top seat 2 and connected to the power mechanism 3, a lower template 5 mounted on the base 1, and an upper template 6 fixedly mounted at the bottom of the connecting plate 4. A demolding lifting mechanism is provided on the base 1 at the bottom of the lower template 5. Two sets of locking assemblies are provided on the left and right sides of the demolding lifting mechanism. Two lifting rods 17 are provided on the bottom sides of the connecting plate 4, and the two lifting rods 17 are located directly above the two sets of locking assemblies.

[0020] Through the above-described structure, this utility model utilizes two lifting rods 17 that, after descending with the connecting plate 4, are correspondingly engaged in two sets of locking assemblies. During the upward reset, the two sets of locking assemblies drive the demolding lifting mechanism to perform a lifting action, pushing out the engine bottom guard plate inside the lower template 5. After the demolding lifting mechanism reaches the lifting limit position, the two lifting rods 17 disengage from the two sets of locking assemblies, and the demolding lifting mechanism resets.

[0021] Specifically, as a further improvement of this embodiment, five demolding lifting through holes 7 are provided around the bottom and center of the lower template 5.

[0022] As a further improvement to this embodiment, the demolding lifting mechanism includes a demolding template 8, five demolding lifting rods 9 disposed on the demolding template 8, and guide slide columns 10 disposed at the bottom of the demolding template 8. The top ends of the five demolding lifting rods 9 are located within five demolding lifting through holes 7, and the guide slide columns 10 are vertically slidably mounted on the base 1. A return spring 11 is sleeved on the guide slide column 10, and the two ends of the return spring 11 are respectively connected to the bottom of the demolding template 8 and the base 1. When the two lifting rods 17 disengage from the two sets of locking assemblies, the return spring 11 ensures that the demolding template 8 automatically resets.

[0023] Furthermore, both sets of locking assemblies include a mounting plate 12 fixedly installed on one side of the release template 8 and arranged longitudinally, and two locking blocks 13 symmetrically arranged and rotatably connected to the mounting plate 12. Each locking block 13 is coaxially connected to a torsion spring, which ensures that the locking block 13 returns to its set state after being subjected to force. The two locking blocks 13 have an L-shaped structure, arranged with one end horizontal and the other end vertically downward. A limiting transverse rod 14 is connected to the bottom of each locking block 13, and the two limiting transverse rods 14 slide in contact with the mounting plate 12. The gap between the two locking blocks 13 is the locking gap, which is located on the descent trajectory of the lifting rod 17. Specifically, in this embodiment, the bottom of the lifting rod 17 is symmetrically provided with two horizontally protruding locking protrusions 18, which can correspondingly engage with the bottom of the horizontal ends of the two locking blocks 13.

[0024] Furthermore, the mounting plate 12 is provided with two arc-shaped trajectory through slots 15. The two arc-shaped trajectory through slots 15 are symmetrically arranged with the rotation points of the two locking blocks 13 as the center. The middle position of the two arc-shaped trajectory through slots 15 is located directly below the rotation points of the two locking blocks 13. The two limiting transverse rods 14 pass through the two arc-shaped trajectory through slots 15 respectively.

[0025] As a further improvement to this embodiment, a side baffle 16 is provided on the side wall of the base 1, and two limiting transverse rods 14 abut against the longitudinal side walls of the side baffle 16. The longitudinal width of the side baffle 16 is the same as the distance between the two arc-shaped trajectory slots 15 at their midpoints, the height of the side baffle 16 is the same as the lifting stroke distance of the demolding lifting mechanism, and the bottom height of the side baffle 16 is flush with the bottom height of the arc-shaped trajectory slots 15.

[0026] Working principle and usage process of this utility model:

[0027] In use, the power mechanism 3 drives the upper template 6 to press down through the connecting plate 4. When the connecting plate 4 contacts the upper end face of the lower template 5, the upper template 6 presses the blank inside the lower template 5 into shape. During this process, the locking protrusion 18 at the bottom of the lifting lever 17 first abuts against the upper side of the horizontal end of the two locking blocks 13, causing them to rotate downwards around their respective rotation points, so that the locking protrusion 18 passes through the two locking blocks 13. The two locking blocks 13 then reset under the action of the torsion spring. After the upper template 6 is stamped and formed, the connecting plate 4 rises and resets, and the lifting lever 17 rises accordingly. The locking protrusion 18 abuts against the bottom of the horizontal end of the two locking blocks 13. At this time, the state is as follows: Figure 5 As shown, in this state, the limiting transverse rod 14 is restricted from rotating by the side baffle 16, such as... Figure 6As shown, the horizontal ends of the two locking blocks 13 remain horizontal, allowing the lifting rod 17 to drive the demolding template 8 to lift through the locking protrusion 18 and the locking blocks 13. The demolding lifting rod 9 on the demolding template 8 extends from the demolding lifting through hole 7, pushing the formed engine underbody plate out of the lower template 5. Since the side baffle 16 is fixedly installed on the base 1, the side baffle 16 remains stationary when the locking assembly rises with the demolding template 8. When the limiting transverse rod 14 disengages from the side of the side baffle 16, the limiting transverse rod 14 loses the lateral limiting force of the side baffle 16. The upward pulling force of the lifting rod 17 will cause the two locking blocks 13 to rotate upward, causing the locking protrusion 18 to pass through the two locking blocks 13, thus disengaging the lifting rod 17 from the locking assembly. At the same time, the demolding template 8 is reset by the return spring 11 at the bottom.

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 the principles of this 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 claims.
