Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold for processing latex pillows. Background Technology

[0002] Latex pillows are sleep products made from natural latex. They have excellent elasticity and resilience, effectively supporting the head and neck, reducing pressure on the body, and improving sleep quality. In addition, latex pillows offer excellent breathability and mite-repellent properties, effectively avoiding the problems of bacteria and allergens that traditional pillows easily harbor.

[0003] The manufacture of latex pillows requires the use of molds for foaming and molding. To ensure that the latex fully fills the entire mold cavity, a relatively large amount of latex is injected during processing. This method increases the chance of latex overflow during the foaming process, necessitating the removal of excess latex adhering to the outer periphery of the latex pillow after foaming and molding. This removal operation requires four steps: sequentially cutting away the excess latex from each of the four outer periphery of the latex pillow. This results in a large workload and reduces the processing efficiency of latex pillows to some extent. Utility Model Content

[0004] The purpose of this invention is to provide a mold for processing latex pillows. Products processed by this mold can make the subsequent removal of excess latex more convenient, thereby reducing the workload of the removal operation and improving the processing efficiency of latex pillows.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a mold for processing latex pillows, including an upper mold, a lower mold, and a pillow mold cavity formed between the upper mold and the lower mold. The upper mold is provided with an edge sealing member that presses the lower mold at the position corresponding to the outer edge of the pillow mold cavity. An overflow structure that communicates with the pillow mold cavity is formed between the upper mold and the lower mold. The overflow structure, together with the edge sealing member, constitutes a surrounding arrangement around the outer periphery of the pillow mold cavity.

[0006] By adopting the above technical solution, the upper and lower molds are combined to form a pillow cavity for containing latex. Then, a sealing component is used to partially seal the outer edge of the pillow cavity, preventing latex from entering the gap between the upper and lower molds during the foaming process, thus avoiding latex overflow at that location. Excess latex formed during foaming enters a specially designed overflow structure, ensuring that the latex fully fills the entire mold cavity. In the subsequent cutting process, workers only need to cut away the overflowing latex on one side of the overflow structure, making the operation more convenient, reducing the workload of cutting operations, and improving the processing efficiency of latex pillows.

[0007] Further configured as: the edge sealing member includes an installation cavity formed in the upper mold, a connection channel connecting the installation cavity and the pillow mold cavity, an edge sealing frame disposed in the installation cavity and extending into the pillow mold cavity through the connection channel, and a control component for controlling the reciprocating movement of the edge sealing frame towards the lower mold.

[0008] By adopting the above technical solution, when the upper mold covers the lower mold, the control component is used to control the edge sealing frame to move towards the lower mold and abut against the lower mold, so as to block the mold closing gap formed between the pillow mold cavity and the upper and lower molds, avoid latex from entering the mold closing gap, and further achieve the edge sealing effect.

[0009] Further configured as: the shape of the edge sealing frame is a U-shaped, and the overflow structure is a long strip shape. The overflow structure and the edge sealing frame cooperate to form a square surrounding the outer periphery of the pillow mold cavity.

[0010] By adopting the above technical solution, the U-shaped edge sealing frame can solve the problem of latex overflow on three sides of the pillow mold cavity, thereby reducing the workload of the later latex overflow cutting operation to the greatest extent and improving the processing efficiency of the pillow. And by setting the overflow structure as a long strip shape, it is convenient for the cutting and cleaning operation of the overflow.

[0011] Further configured as: the overflow structure is an overflow gap formed between the upper mold and the lower mold and communicating the pillow mold cavity with the outside.

[0012] By adopting the above technical solution, the overflow gap is provided for the discharge of excess colloid.

[0013] Further configured as: the control component includes a return spring for driving the edge sealing frame to move away from the lower mold and a tightening bolt threadedly connected to the upper mold and used for driving the edge sealing frame to move towards the lower mold.

[0014] By adopting the above technical solution, the return spring and the tightening bolt cooperate to control the reciprocating movement of the edge sealing frame towards the lower mold, with a simple structure and low production cost.

[0015] Further configured as: the edge sealing frame is in sealed sliding fit with the connection channel.

[0016] By adopting the above technical solution, the colloid is prevented from entering the connection channel by means of sealed sliding fit.

[0017] Further configured as: a slot for inserting the edge sealing frame is formed at the position of the lower mold corresponding to the edge sealing frame.

[0018] By adopting the above technical solution, the slot is provided to better cooperate with the designed edge sealing frame structure to form a more even-edge pillow mold cavity structure.

[0019] Further configured as: the upper mold and the lower mold are hinged.

[0020] By adopting the above technical solution, the mold opening and closing operation is facilitated.

[0021] In summary, the utility model has the following beneficial effects: The product processed by the utility model can make the later glue overflow cutting operation more convenient, so as to reduce the workload of the cutting operation and improve the processing efficiency of the latex pillow.
