Description

Technical Field

[0001] The utility model relates to the field of latex product production, in particular to a demoulding device for latex product production. Background Art

[0002] Latex pillows are made from the sap of rubber trees through a full physical process. Latex is a very environmentally friendly material, so its application range is also very wide. Due to the unique frankincense smell of rubber sap, the latex pillow made has the effect of anti-mite and antibacterial. At the same time, due to the production process, latex pillows often have a honeycomb air vent design. Compared with other pillows, latex pillows are more breathable and can discharge the sweat and heat generated by the human body during sleep through natural circulation. The production of latex pillows is to inject the pre-treated latex into the mold, steam it in a high-temperature steamer, and finally take out the formed latex pillow from the mold.

[0003] The existing molds for latex pillows are mostly opened and demolded manually during the production process. The mold adopts a structure in which the upper mold and the lower mold are separated. The latex pillow is easy to stick to the inside of the mold base, and demolding is very difficult, which brings great trouble to the staff. After the latex pillow is demolded, the upper mold and the lower mold need to be repositioned, making the overall steps cumbersome and labor-intensive. Utility Model Content

[0023] like Figures 1 to 5 As shown, the utility model provides a demoulding device for latex product production, including a lower mold base 1 and an upper mold base 2, the lower mold base 1 is provided with a stepped slot 4 with a bottom opening inside, a demoulding assembly 5 is movably installed at the bottom of the lower mold base 1, and the demoulding assembly 5 includes a bidirectional screw 52 rotatably connected to the inner side of the bottom of the lower mold base 1, and the left and right sides of the outside of the bidirectional screw 52 are both threadedly connected with sliding blocks 53, the top of the sliding block 53 is movably hinged with a connecting rod 54, and the other end of the connecting rod 54 is movably hinged with a connecting block 55 on the outside, the top of the connecting block 55 is fixedly connected with a lifting base 56 clamped in the stepped slot 4, and the docking surface of the lower mold base 1 and the upper mold base 2 is provided with a positioning assembly 6.

[0024] By means of a demoulding assembly 5 disposed at the bottom of the lower mold base 1, the sliding blocks 53 on both sides thereof are driven to push the connecting rod 54 inward by rotating the bidirectional screw 52, ​​and the jacking base 56 connected to the connecting block 55 is pushed upward along the stepped slot 4 by the connecting rod 54, so that the latex pillow stuck in the lower mold base 1 is pushed upward and ejected to avoid it from sticking to the inside of the lower mold base 1, which is convenient for demoulding. At the same time, by means of a positioning assembly 6 disposed at the interface between the lower mold base 1 and the upper mold base 2, the sleeve rod 64 at the bottom of the upper mold base 2 is chamfered with the buffer spring 63 in the positioning groove 61, so that the sleeve rod 64 is conveniently inserted into the positioning groove 61 and the positioning column 62 is inserted into the sleeve rod 64, so that the lower mold base 1 and the upper mold base 2 are conveniently docked and positioned, and the buffer spring 63 is provided to provide buffering during docking.

[0025] like Figure 3 As shown, the bottom of the lower die base 1 is fixedly connected to a fixing frame 51 , and the sliding block 53 is attached to the top of the fixing frame 51 .

[0026] The fixing frame 51 is provided to provide support for the bidirectional screw 52 to ensure stability, and the sliding block 53 is attached to the top of the fixing frame 51 , and the fixing frame 51 provides a limit for the sliding block 53 .

[0027] like Figure 3As shown, one side of the bidirectional screw 52 is fixedly connected to an operating hand wheel 57 located on the outer side of the lower die base 1 .

[0028] By rotating the operating hand wheel 57, the bidirectional screw rod 52 is driven to rotate forward and reversely, thereby controlling the lifting base 56 to perform lifting operations.

[0029] like Figure 2 and Figure 3 As shown, a sealing strip 58 adapted to the stepped slot 4 is movably engaged with the outer edge of the bottom of the lifting base 56 .

[0030] The sealing strip 58 is located at the bottom of the lifting base 56 and is pressed against the bottom of the stepped slot 4 along with the lifting base 56 to ensure sealing.

[0031] like Figure 4 and Figure 5 As shown, the alignment component 6 includes an alignment groove 61 opened at the four corners of the top of the lower mold base 1, an alignment column 62 is fixedly installed inside the alignment groove 61, and a buffer spring 63 is movably sleeved outside the alignment column 62. The four corners of the bottom of the upper mold base 2 are fixedly connected with a hollow sleeve rod 64, and the sleeve rod 64 is movably clamped in the interior of the alignment groove 61.

[0032] By arranging the sleeve rod 64 at the bottom of the upper die base 2 to correspond to the alignment groove 61 at the top of the lower die base 1, and since the bottom of the sleeve rod 64 is chamfered inward, it is convenient to insert the sleeve rod 64 into the interior of the alignment groove 61, and the sleeve rod 64 is moved downward along the alignment groove 61 to allow the alignment column 62 to be inserted into the interior of the sleeve rod 64, thereby facilitating the positioning and docking of the lower die base 1 and the upper die base 2, and the buffer spring 63 is squeezed by the sleeve rod 64 to provide a buffer, thereby avoiding rigid contact between the lower die base 1 and the upper die base 2.

[0033] like Figure 4 and Figure 5 As shown, the sleeve rod 64 is sleeved on the outside of the alignment post 62, and the bottom of the sleeve rod 64 and the top of the alignment post 62 are both chamfered.

[0034] The alignment groove 61, the alignment column 62 and the sleeve rod 64 are all coaxially arranged.

[0035] The chamfered joints of the alignment post 62 and the sleeve rod 64 facilitate alignment connection so that the sleeve rod 64 is inserted into the alignment groove 61 and the alignment post 62 is inserted into the sleeve rod 64 to facilitate positioning and docking of the lower die base 1 and the upper die base 2.

[0036] like Figure 1 As shown, ear plates are provided on both the front and rear sides of the lower die base 1 and the upper die base 2, and locking bolts 3 are movably connected inside the ear plates.

[0038] The working principle of the demoulding device for latex product production will be described in detail below.

[0039] like Figures 1 to 5 As shown, by making the sleeve rod 64 at the bottom of the upper mold base 2 correspond to the alignment groove 61 at the top of the lower mold base 1, since the bottom of the sleeve rod 64 is chamfered inward, it is convenient to insert the sleeve rod 64 into the interior of the alignment groove 61, and the sleeve rod 64 moves down along the alignment groove 61 to make the alignment column 62 insert into the interior of the sleeve rod 64, and when the lower mold base 1 and the upper mold base 2 are connected, the sleeve rod 64 squeezes the buffer spring 63 to provide buffering to avoid rigid contact between the lower mold base 1 and the upper mold base 2, thereby facilitating the positioning of the lower mold base 1 and the upper mold base 2, and after the lower mold base 1 and the upper mold base 2 are closed, the locking bolts 3 are used to pass through the ear plates on the front and rear sides of the lower mold base 1 and the upper mold base 2 to connect and fix them, and latex is injected into the mold cavities in the lower mold base 1 and the upper mold base 2 through the glue injection port set on the upper mold base 2. After molding, the upper mold base 2 is opened and By rotating the operating handwheel 57 located at the lower outer side of the lower mold base 1, the bidirectional screw 52 located at the bottom of the lower mold base 1 is driven to rotate through the operating handwheel 57, and the sliding blocks 53 on both sides are driven to slide inward through the rotation of the bidirectional screw 52. The sliding blocks 53 slide inward along the fixed frame 51 to push the connecting rod 54 inward, and the connecting block 55 hinged at its end is pushed by the connecting rod 54 to push the jacking base 56 located in the step slot 4 to move upward, and the molded latex pillow located inside the lower mold base 1 is pushed upward by the jacking base 56, so as to facilitate demolding and removal, and the sliding block 53 drives the jacking base 56 to move downward through the reverse operation 67, and the bidirectional screw 52 has a self-locking property so that the sealing strip 58 at the bottom of the jacking base 56 is pressed against the inner side of the step slot 4 to ensure sealing.
