Description

TECHNICAL FIELD

[0001] The utility model relates to latex pillow production technical field, and specifically is a latex setting device. BACKGROUND

[0002] The setting process of latex pillow produced by the Trelat method includes the following key steps: firstly, uniformly mixing natural rubber emulsion and additives; injecting the mixed emulsion into a specially-made aluminum mold; after the mold is closed, cooling and vacuum treatment are carried out; the cooled mold freezes the foam to about -30 DEG C to help the solidification of the latex foam; carbon dioxide gas is used to flow through the frozen block to make the foam "solidified" or "gelled"; after the gelling is completed, the mold is heated to 110 DEG C for several minutes to cause the rubber to "harden" or "vulcanize"; the vulcanized latex pillow is taken out of the mold and washed; finally, the latex pillow is dried or baked to remove excess moisture.

[0003] The current Trelat method for producing latex pillows involves two temperature treatment steps of freezing and heating. Most of the temperature treatment methods directly place the mold in a suitable temperature environment created by a freezer or heating equipment. The external temperature environment needs to pass through the mold first and then be transferred to the surface layer of the latex pillow, and finally gradually transferred to the inside of the latex pillow. The heat conduction efficiency has room for improvement, and the temperature treatment is seriously layered inside the latex pillow, affecting the quality of the latex pillow. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0044] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0045] Please refer to Figures 1-5 In the embodiments of the utility model, a latex shaping device comprises a shaping bottom mold 1, a shaping upper mold 2, a locking structure 3 and a heat source structure 4. The shaping bottom mold 1 comprises a bottom mold main body 101. The shaping upper mold 2 comprises an upper mold main body 201. The rear side edge of the upper mold main body 201 is hingedly connected with the rear side edge of the bottom mold main body 101. The upper mold main body 201 is provided with a heat source clamping groove 205 on the upper surface. The bottom side of the upper mold main body 201 is fixedly provided with a plurality of heat conduction needle covers 204 which are in communication with the heat source clamping groove 205. The front side edges of the bottom mold main body 101 and the upper mold main body 201 are locked with each other by the locking structure 3. The heat source structure 4 comprises a heat conduction plate 401. The bottom side of the heat conduction plate 401 is clamped with the heat source clamping groove 205. The heat conduction plate 401 is internally provided with a heat medium flow cavity 404. The bottom side of the heat conduction plate 401 is fixedly provided with a plurality of heat conduction needle bodies 403 which are in communication with the heat medium flow cavity 404. The heat conduction needle bodies 403 are sleeved with the heat conduction needle covers 204.

[0046] Specifically, latex is injected into the mold body 101 and the upper mold body 201, which together form the mold assembly. The lower mold body 101 and the upper mold body 201 are locked together by a locking structure 3 and a hinge. Heat-conducting plates 401 are installed in the freezer and heating equipment by bolts, and the liquid heat-conducting medium flow channel and the heat medium flow cavity 404 inside the freezer and heating equipment are interconnected. When the mold assembly moves into the freezer and heating equipment, the heat-conducting plates 401 are snapped into the heat source receiving groove 205, and the heat-conducting pins 403 and heat-conducting pin sleeves 204 are interlocked. Each heat-conducting pin sleeve 204 is directly inserted into the latex. When the heat-conducting medium flows into the heat medium flow cavity 404, it flows into each heat-conducting pin 403, and the low or high temperature it carries is directly transferred to the interior of the latex through the heat-conducting pins 403 and heat-conducting pin sleeves 204. Temperature effects are applied simultaneously from the inside and outside of the latex, effectively improving the freezing and heating effects.

[0049] In this embodiment, when the bottom mold body 101 and the upper mold body 201 are closed together, a complete molding cavity is formed by the lower mold cavity 104 and the upper mold cavity 203. Foaming latex is injected from the latex injection port 206, and the air in the cavity is squeezed out from the exhaust port 207. The base 102 and the snap-fit ​​groove 103 are snapped together with the mold limiting structure to achieve a relatively fixed position. When it is necessary to open or close the upper mold body 201, force is applied to the handle 202 to open the upper mold body 201.

[0050] like Figure 1 , 5As shown, in this embodiment, the heat source structure 4 further includes a seal 402, a liquid inlet 405, and a liquid outlet 406. The seal 402 is fixedly installed on the middle of the bottom side of the heat-conducting plate 401, and the seal 402 is interlocked with the latex injection port 206.

The liquid outlet 406 is opened on the other edge of the upper surface of the heat-conducting plate 401 and is connected to the heat medium flow cavity 404.

[0051] In specific implementation, when the heat source locking groove 205 and the heat conduction plate 401 are locked together, the sealing port 402 is inserted into the latex injection port 206 to seal the latex injection port 206. At the same time, the liquid inlet port 405 and the liquid outlet port 406 are connected to the heat conduction medium flow channel inside the refrigerator and heating equipment.

[0052] Example 2

[0053] Based on Embodiment 1, in order to supplement the specific method of locking by locking structure 3 when the bottom mold body 101 and the upper mold body 201 are closed together, which was not mentioned in Embodiment 1.
