Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an automatic mold splitting and part discharging tooling for a rubber shock pad mold. Background Art

[0002] A rubber shock pad needs to be arranged between an elevator car and an external frame to ensure the stable operation of the elevator car. To ensure a certain stiffness of the rubber shock pad and its service life, rigid plates need to be added to the upper and lower surfaces of the rubber elastomer respectively. This product injects vulcanized rubber in a molten state into a mold, applies rubber to the surfaces of the upper and lower rigid plates, and is pressure-cured into shape. Currently, manual mold opening is used for rubber coating of rubber blocks with skeletons. The reason is that the middle-layer mold is usually composed of multiple mold segments, and when using an oil cylinder to split, only the two outermost mold segments can be split, and the mold segments in the middle part cannot be split. Manual mold opening not only has a large labor intensity, but also the force application during the process of splitting and combining the molds is not stable, resulting in a reduction in mold accuracy, a large batch error rate of products, and a large impact and wear on the mold itself, reducing the service life of the mold. Content of the Utility Model

[0003] In view of the above problems, the utility model provides an automatic mold splitting and part discharging tooling for a rubber shock pad mold, which can realize automatic splitting of the mold by using the kinetic energy provided by an equipment oil cylinder.

[0004] To achieve the above purposes, the following technical solutions are adopted: an automatic mold splitting and part discharging tooling for a rubber shock pad mold, including an upper-layer mold, a middle-layer mold, and a bottom-layer mold.

[0005] The middle-layer mold is an integral mold formed by docking five mold segments. The upper and lower end faces of the middle-layer mold are respectively docked with the upper-layer mold and the bottom-layer mold. The five mold segments include a fixed segment and two mold splitting segment groups. The mold splitting segment group includes a first mold splitting segment and a second mold splitting segment. A mold cavity and a two-stage injection runner are formed at the docking part of the mold segments. The two-stage injection runner is communicated with the mold cavity. Fixed plates are arranged on both sides of the fixed segment. First sliding plates are arranged on both sides of the two first mold splitting segments. First mold splitting plates are arranged on the mold splitting direction sides of the two second mold splitting segments. Second sliding plates are arranged on both sides of the two second mold splitting segments. The adjacent first mold splitting segment and second mold splitting segment are connected with a sliding rod through the first sliding plates and second sliding plates on both sides. The first sliding plates and second sliding plates are installed on the sliding rod to ensure that when the second mold splitting segment is pulled by an external force, the second sliding plate slides on the sliding rod and when it slides to the maximum displacement, the sliding rod is linked with the first sliding plate.

[0006] On the upper mold, there is a first injection runner corresponding to the second-stage injection runner. Each first injection runner and the corresponding second-stage injection runner form a complete injection runner. On the upper surface of the upper mold, there is a material distribution runner, which is connected to each first injection runner. On two corresponding frames of the upper mold, there are second sub-molds respectively;

[0007] On the bottom mold, there is a mold cavity base corresponding to the mold cavity of the middle mold. On two corresponding frames of the bottom mold, there are third sub-molds respectively.

[0008] Furthermore, first and second limit blocks are respectively arranged at both ends of the sliding rod. The first limit block is located on one side of the first sliding plate, and the second limit block is located on one side of the second sliding plate.

[0009] Furthermore, the length of the sliding rod is greater than 2.1 times the width of the mold cavity, ensuring the demolding of the products in the mold cavity formed by the first and second split mold petals and the mold cavity formed by the first split mold petal and the fixed petal.

[0010] Furthermore, the first sub-mold, the second sub-mold, the third sub-mold, and the fixed plate are provided with mounting holes for docking with the equipment.

[0011] Furthermore, on the lower surface of the upper mold, there is a first groove adapted to the upper end surface of the middle mold. On the upper surface of the bottom mold, there is a second groove adapted to the lower end surface of the middle mold. The upper and lower end surfaces of the middle mold are respectively docked with the first and second grooves, and the docking surfaces are in inclined surface fit.

[0012] Advantages of the present utility model: In the present novel, sub-molds connected to the equipment are provided on the upper mold, the middle mold, and the bottom mold, which can utilize the oil cylinder of the equipment to provide kinetic energy to split the three-layer mold. The middle mold is designed as an integral mold formed by five mold petals docking with each other. A fixed plate is arranged on the fixed petal. Sliding plates that can be docked on the tracks of the equipment are arranged on the first and second split mold petals, and the sliding plates between the two are connected by a sufficiently long sliding rod, so that when the first split mold petal is forced to slide and separate by a certain distance, it drives the second split mold petal to separate, and finally the five mold petals are separated. The present novel can be applied to the equipment. Through the linkage of the first and second split mold petals, the middle mold is split, saving the labor of manual mold opening, ensuring the position accuracy of the mold during the splitting and combination processes, and reducing errors.

The cylinder mechanism of the equipment is activated, and the second sub-mold 10 and the third sub-mold 30 of the upper mold 1 and the bottom mold 3 are subjected to force in the vertical direction, so that the upper, middle and bottom three-layer molds are in the vertical direction. Separation in the vertical direction, the middle mold 2 is subjected to force in the horizontal direction, first, the first mold plate 26 on the second mold flap 22 is subjected to pulling force, so that the second mold flap 22 is separated and displaced along the slide bar 27, during this process, the second mold flap 22 and the first mold flap 21 are separated, when the second sliding plate 25 slides to the position of the second limit block 29, the second mold flap 22 drives the slide bar 27 to operate in conjunction, since the first sliding plate 24 is subjected to the force of the first limit block 28, the first sliding plate 24 is separated and displaced in conjunction with the slide bar 27, at this time, the first mold flap 21 and the fixed flap 20 are separated, when the first mold flap 21 and the second mold flap 22 and the first mold flap 21 and the fixed flap 20 completely complete the separation action, the product is demoulded.
