Description

Technical Field

[0001] This application relates to the field of die molds, and in particular, to a new type of PVC material die mold. Background Technique

[0002] Polyvinyl chloride plastic is polymerized from vinyl chloride monomers and is one of the commonly used thermoplastic plastics. Its trade name is simply referred to as "chloroplastics", and its English abbreviation is PVC.

[0003] Common sponge blocks made of PVC often need to be stamped and cut by a die mold with a predetermined shape to meet the requirements of the design pattern. However, for relatively thick sponge blocks, after the die mold is embedded in it, the friction generated is relatively large, which easily causes the cut sponge and the surrounding sponge to rise together with the die mold after cutting, and then workers are required to separate it from the die mold, adding processing steps and reducing processing efficiency.

[0004] The above information disclosed in this background technique is only used to increase the understanding of the background of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Content of the Utility Model

[0005] In order to solve the problem that for relatively thick sponge blocks, after the die mold is embedded in it, it is easy for the cut sponge and the surrounding sponge to rise together with the die mold after cutting, and subsequent manual separation is required, this application provides a new type of PVC material die mold. The new type of PVC material die mold provided by this application adopts the following technical solutions:

[0006] A new type of PVC material die mold, including a support table and a stamping mechanism. A bottom plate is installed on the upper surface of the support table. Support columns are fixed at the four corners of the upper surface of the bottom plate. A top plate is fixed between the tops of the four support columns. A limiting mechanism for limiting the sponge block is installed between the top plate and the bottom plate;

[0007] Connecting rods are fixedly connected to both sides of the lower surface of the top plate. A fixing plate is installed between the bottoms of the two connecting rods on both sides. Ejector rods are installed on both sides of the lower surface of the fixing plate, and the bottoms of the ejector rods are wrapped with rubber contact heads.

[0008] Preferably, the limiting mechanism includes four rectangular adjusting sleeves, four rectangular adjusting rods, four fastening nuts, and a limiting fence. The four rectangular adjusting sleeves are respectively fixed on both sides of the lower surface of the top plate. The four rectangular adjusting rods are sequentially sleeved inside the corresponding rectangular adjusting sleeves. The four fastening nuts are screwed on the bottoms of the four rectangular adjusting sleeves. The limiting fence is installed between the bottoms of the four rectangular adjusting rods.

[0009] Preferably, the stamping mechanism includes a hydraulic cylinder, a lower pressing frame, and a die body. The hydraulic cylinder is installed on the lower surface of the top plate, the lower pressing frame is installed at the bottom of the hydraulic cylinder, and the die body is installed below the lower pressing frame.

[0010] Preferably, guide plates are fixed on both sides of the upper surface of the die body, and the outside of the guide plates sequentially penetrates through the inside of the fixing plate and the top plate from bottom to top.

[0011] Preferably, a rectangular notch is formed inside the fixing plate, so that the lower pressing frame can move within the notch.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] By adjusting the position heights of the rectangular adjusting rod and the limiting fence, the distance between the limiting fence and the bottom plate is adapted to the sponge block to be stamped and cut, so that the outer part of the sponge block can be limited. Cooperating with the four ejector rods and the rubber contact heads, the sponge block cut and stuck inside the die body can be ejected and separated. The whole process does not require the staff to manually separate the sponge stuck outside the die body, saving operation steps and improving processing efficiency. Description of the Drawings

Detailed Embodiment

[0018] The following further describes the present application in detail Figures 1 - 3 with reference to the attached

[0019] The embodiment of the present application discloses a new type of PVC material die mold. Refer to Figure 1 and Figure 2 and Figure 3, a new type of PVC material die mold, including a support table 13 and a stamping mechanism. A bottom plate 12 is installed on the upper surface of the support table 13. The sponge block placed on the upper surface of the bottom plate 12 can be processed by the stamping mechanism. At the same time, support columns 10 are fixed at the four corners of the upper surface of the bottom plate 12. A top plate 1 is fixed between the tops of the four support columns 10. A limiting mechanism for limiting the sponge block is installed between the top plate 1 and the bottom plate 12. The peripheral part of the sponge block can be limited by the limiting mechanism to prevent it from moving up with the stamping mechanism;

[0020] At the same time, connecting rods 16 are fixedly connected to both sides of the lower surface of the top plate 1. A fixing plate 7 is installed between the bottoms of the two connecting rods 16. Ejector rods 15 are installed on both sides of the lower surface of the fixing plate 7, and rubber contact heads 14 are wrapped around the bottoms of the ejector rods 15. By cooperating with the four ejector rods 15 and the rubber contact heads 14, the sponge block cut and stuck inside the stamping mechanism can be ejected.

[0021] Refer to Figure 1 and Figure 2 , the limiting mechanism includes four rectangular adjusting sleeves 2, four rectangular adjusting rods 3, four fastening nuts 11 and a limiting fence 4. The four rectangular adjusting sleeves 2 are respectively fixed on both sides of the lower surface of the top plate 1. The four rectangular adjusting rods 3 are sequentially sleeved inside the corresponding rectangular adjusting sleeves 2. The four fastening nuts 11 are screwed onto the bottoms of the four rectangular adjusting sleeves 2. The limiting fence 4 is installed between the bottoms of the four rectangular adjusting rods 3. The rectangular adjusting rod 3 can move inside the rectangular adjusting sleeve 2 to change the position height of the limiting fence 4, which is convenient for adapting to sponge blocks of different specifications and thicknesses. At the same time, by screwing the fastening nut 11 into the rectangular adjusting sleeve 2 and the fastening nut 11 abuts against the outer surface of the rectangular adjusting rod 3, it is convenient to limit the rectangular adjusting rod 3 to ensure the stability of the limiting fence 4 after adjustment.

[0022] Refer to Figure 1 and Figure 2 , the stamping mechanism includes a hydraulic cylinder 8, a lower pressing frame 6 and a die body 5. The hydraulic cylinder 8 is installed on the lower surface of the top plate 1. The lower pressing frame 6 is installed at the bottom of the hydraulic cylinder 8. The die body 5 is installed below the lower pressing frame 6. By starting the hydraulic cylinder 8, the bottom of the hydraulic cylinder 8 can push the lower pressing frame 6 downward, and then the lower pressing frame 6 pushes the die body 5 downward to realize the stamping and cutting of the sponge block.

[0023] Refer to Figure 1 and Figure 2 , guide plates 9 are fixed on both sides of the upper surface of the die body 5, and the guide plates 9 penetrate through the fixing plate 7 and the inside of the top plate 1 from bottom to top in sequence, which is convenient for limiting both sides of the die body 5 and improving the stability of the trajectory when the die body 5 moves up and down.

[0024] Refer to Figure 1 and Figure 2 andFigure 3 , a rectangular notch is formed inside the fixing plate 7, so that the lower pressing frame 6 can move within the notch, avoiding affecting the up and down movement of the die body 5 and facilitating the processing of the sponge block by the die body 5.

[0025] The implementation principle of a new type of PVC material die mold in the embodiment of the present application is as follows:

[0026] During use, first loosen the four fastening nuts 11 in sequence, adjust the position height of the rectangular adjusting rod 3 and the limiting fence 4, so that the distance between the limiting fence 4 and the bottom plate 12 is adapted to the sponge block to be punched and cut. Then place the sponge block to be processed on the upper surface of the bottom plate 12, start the hydraulic cylinder 8, so that the bottom of the hydraulic cylinder 8 can push the lower pressing frame 6 downward, and then the lower pressing frame 6 pushes the die body 5 downward to realize the punching and cutting of the sponge block;

[0027] When the cutting is completed, start the hydraulic cylinder 8 again to drive the die body 5 to move upward. At this time, the limiting fence 4 can limit the sponge block on the periphery of the cut to prevent it from moving upward synchronously with the die body 5. At the same time, by cooperating with the four ejector rods 15 and the rubber contact heads 14, the sponge block cut and stuck inside the die body 5 can be ejected and separated. The whole process does not require the staff to manually separate the sponge stuck outside the die body 5, saving operation steps and improving processing efficiency.
