[0002] Car floor mats are interior structural elements installed on the bottom of a car's interior, serving to decorate, prevent slipping, absorb water, and protect equipment.

[0003] In existing automotive floor mat injection molding technology, there is a defect that the floor mats cannot be automatically demolded.

[0004] For example, CN208826873U, a molding die for car floor mats; CN216423139U, a mold for car floor mats; and CN219445935U, an injection mold for car floor mats. All of these patents suffer from the problem of requiring workers to manually remove the molded floor mats, which is time-consuming and labor-intensive, and they cannot automatically demold, thus reducing production efficiency.

[0005] Therefore, it is necessary to develop a car floor mat mold to address the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide a car floor mat mold that can automatically demold the floor mat after it is formed.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] This utility model discloses a car floor mat mold, comprising an upper mold and a lower concave mold. The upper mold is located directly above the lower concave mold and includes a support. The upper mold is fixed to the lower surface of the top plate of the support. A guide rod assembly is fixed on the top plate, penetrating the upper mold and slidably penetrating the lower concave mold and fixedly connected to a fixing plate. A telescopic rod is fixed to the lower surface of the fixing plate, and the telescopic end of the telescopic rod slidably penetrates the fixing plate and is fixedly connected to the bottom surface of the lower concave mold. The lower concave mold has a cavity, and the top wall of the cavity has multiple sliding holes that communicate with the forming cavity of the lower concave mold. Each sliding hole is slidably connected to a lifting rod for demolding the floor mat, and the bottom end of the lifting rod slidably penetrates the bottom surface of the lower concave mold. A limit block is fixed on the lifting rod, and the limit block is supported on the bottom wall of the cavity.

[0009] Optionally, a compression spring is also included, with each of the lifting rods fitted with a compression spring, the top end of the compression spring abutting against the top wall of the cavity, and the bottom end of the compression spring abutting against the limiting block.

[0010] Optionally, the guide rod assembly includes four slide rods, which are arranged one-to-one with the four corners of the lower die. The slide rods slide through the lower die and the upper die and are fixedly connected to the top plate. The fixing plate is fixedly connected to the bottom end of the slide rod.

[0011] Optionally, the top end of the slide rod is threaded and threadedly connected to the top plate, and the top end of the slide rod passes through the top plate and is threadedly connected to a locking nut.

[0012] Optionally, the upper mold includes a fixing module and a pattern template. The fixing module is fixedly connected to the top plate by bolts. The bottom surface of the fixing module is provided with a receiving groove, and the top of the pattern template is detachably connected to the receiving groove.

[0014] Optionally, the telescopic rod can be a pneumatic telescopic cylinder, an electric telescopic cylinder, or a hydraulic cylinder.

[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0016] This utility model discloses a car floor mat mold. After the floor mat is formed, the telescopic end of the telescopic rod drives the lower die to descend and move away from the upper die. Then, the lifting rod and the floor mat descend synchronously. When the bottom end of the lifting rod contacts the fixed plate, the telescopic end of the telescopic rod continues to drive the lower die to descend. Then, the top end of the lifting rod enters the forming cavity. The floor mat in the forming cavity is held in place by the lifting rod and cannot descend with the lower die. When the top surface of the lower die is lower than the top surface of the lifting rod, the telescopic rod stops working. At this time, the floor mat is automatically demolded, saving manpower and material resources and improving production efficiency. Attached Figure Description

[0022] The core of this utility model is to provide a car floor mat mold that can automatically demold after the floor mat is formed.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In some embodiments, the system includes an upper mold 1 and a lower mold 2, with the upper mold 1 located directly above the lower mold 2. The system further includes a support 3. The upper mold 1 is fixed to the lower surface of a top plate of the support 3. A guide rod assembly is fixed to the top plate, penetrating the upper mold 1 and slidingly penetrating the lower mold 2. A fixed plate 4 is fixedly connected to the guide rod assembly. A telescopic rod 5 is fixed to the lower surface of the fixed plate 4, with its telescopic end slidingly penetrating the fixed plate 4 and fixedly connected to the bottom surface of the lower mold 2. The lower mold 2 has a cavity 201, with multiple sliding holes on its top wall. These sliding holes communicate with the forming cavity 202 of the lower mold 2. Each sliding hole is slidably connected to a lifting rod 6 for demolding the foot pad 11, with the bottom end of the lifting rod 6 slidingly penetrating the bottom surface of the lower mold 2. A limiting block 7 is fixed to the lifting rod 6, and the limiting block 7 rests on the bottom wall of the cavity 201.

[0026] Specifically, after the foot pad 11 is formed, the telescopic end of the telescopic rod 5 drives the lower die 2 to descend and move away from the upper die 1. Then the lifting rod 6 and the foot pad 11 descend synchronously. When the bottom end of the lifting rod 6 contacts the fixed plate 4, the telescopic end of the telescopic rod 5 continues to drive the lower die 2 to descend. Then the top end of the lifting rod 6 enters the forming cavity 202. The foot pad 11 in the forming cavity 202 is held by the lifting rod 6 and cannot descend with the lower die 2. When the top surface of the lower die 2 is lower than the top surface of the lifting rod 6, the telescopic rod 5 stops working. At this time, the foot pad 11 completes automatic demolding.

[0027] In addition, the cooling system for cooling the upper mold 1 and the lower mold 2, the injection port for casting, the vent, and other related auxiliary structures are existing technologies and can be manufactured according to customer requirements in actual applications, so they will not be described in detail here. This utility model can be used even without these auxiliary structures. For example, the molten raw material can be directly poured into the molding cavity 202, then the mold can be closed, and the mold can be opened after the foot pad 11 has cooled and solidified naturally.

[0028] The top of the lifting rod 6 can be flush with or 1 to 2 millimeters below the top of the sliding hole.

[0029] In some embodiments, a compression spring 8 is also included, with each lifting rod 6 fitted with a compression spring 8, the top end of the compression spring 8 abutting against the top wall of the cavity 201, and the bottom end of the compression spring 8 abutting against the limiting block 7.

[0030] Specifically, after the worker removes the foot pad 11 on the lifting rod 6, the telescopic rod 5 drives the lower die 2 to rise, eventually causing the lower die 2 to close with the upper die 1. Before the bottom wall of the cavity 201 contacts the limiting block 7, the bottom end of the lifting rod 6 is always in contact with the fixed plate 4 because the compression spring 8 exerts a pushing force on the limiting block 7. As the lower die 2 rises, the top end of the lifting rod 6 re-enters the sliding hole, and the lifting rod 6 resets. If the compression spring 8 is not provided, the friction between the lifting rod 6 and the sliding hole may prevent the top end of the lifting rod 6 from re-entering the sliding hole. Therefore, the provision of the compression spring 8 can improve the automation level of the device.

[0031] In some embodiments, the guide rod assembly includes four slide rods 9, which are arranged one-to-one with the four corners of the lower die 2. The slide rods 9 slide through the lower die 2, slide through the upper die 1 and are fixedly connected to the top plate, and the fixing plate 4 is fixedly connected to the bottom end of the slide rods 9.

[0032] Specifically, the slide bar 9 guides the sliding direction of the lower die 2, making it easier for the lower die 2 and the upper die 1 to close accurately.

[0033] In some embodiments, the top end of the slide rod 9 is threaded and threadedly connected to the top plate, and the top end of the slide rod 9 passes through the top plate and is threadedly connected to a locking nut 10. This is a fixed connection method between the slide rod 9 and the top plate.

[0034] In some embodiments, the upper mold 1 includes a fixing module 101 and a pattern template 102. The fixing module 101 is fixedly connected to the top plate by bolts 103. The bottom surface of the fixing module 101 is provided with a receiving groove, and the top of the pattern template 102 is detachably connected to the receiving groove.

[0035] Specifically, the top of the pattern template 102 is detachably connected to the receiving groove, so the pattern template 102 can be replaced, thereby allowing the replacement of pattern templates 102 of different thicknesses, which can produce foot pads 11 of different thicknesses; and the replacement of pattern templates 102 with different patterns can produce foot pads 11 with different patterns, thus improving applicability.

[0036] In some embodiments, the outer surface of the fixing module 101 has multiple insertion holes into which screws 104 are inserted. The pattern template 102 has blind holes 105 on its side wall inside the receiving groove, which correspond one-to-one with the screws 104. The blind holes 105 are threadedly connected to the screws 104. This is a detachable connection method between the pattern template 102 and the receiving groove.

[0037] In some embodiments, the telescopic rod 5 is a pneumatic telescopic cylinder, an electric telescopic cylinder, or a hydraulic cylinder.

[0038] Working process and principle: After the foot pad 11 is formed, the telescopic end of the telescopic rod 5 drives the lower die 2 to descend and move away from the upper die 1. Then the lifting rod 6 and the foot pad 11 descend synchronously. When the bottom end of the lifting rod 6 contacts the fixed plate 4, the telescopic end of the telescopic rod 5 continues to drive the lower die 2 to descend. Then the top end of the lifting rod 6 enters the forming cavity 202. The foot pad 11 in the forming cavity 202 is held by the lifting rod 6 and cannot descend with the lower die 2. When the top surface of the lower die 2 is lower than the top surface of the lifting rod 6, the telescopic rod 5 stops working. At this time, the foot pad 11 completes automatic demolding.

[0039] After the staff removes the foot pad 11 on the lifting rod 6, the telescopic rod 5 drives the lower die 2 to rise, eventually causing the lower die 2 to close with the upper die 1. Before the bottom wall of the cavity 201 contacts the limiting block 7, the bottom end of the lifting rod 6 is always in contact with the fixed plate 4 because the compression spring 8 exerts a pushing force on the limiting block 7. As the lower die 2 rises, the top end of the lifting rod 6 re-enters the sliding hole, and the lifting rod 6 resets. After the lifting rod 6 resets, it rises with the lower die 2, and finally the lower die 2 and the upper die 1 complete the mold closing.
