Abstract
Description
Technical Field
[0001] The utility model specifically relates to a mold cavity temperature testing probe for a rotorless vulcanizer. Background Art
[0002] The rotorless vulcanizer is an analytical device that can be used to analyze the thermal vulcanization properties of vulcanized rubber. Its cavity structure makes the shear heat of the test process negligible. It also has a constant temperature characteristic and can test the thermal vulcanization properties of vulcanized rubber at a constant temperature. Therefore, it can also be used to analyze the thermal vulcanization properties of peroxide cross-linked polyethylene insulation materials.
[0003] However, the rotorless vulcanizer will have inaccurate mold cavity temperature after long-term use, which requires regular testing of the mold cavity temperature. The rotorless vulcanizer needs to tightly close the upper and lower mold cavities when working, and the sample is placed between the two mold cavities to ensure that the temperature does not dissipate. The traditional temperature measurement method is to open the upper and lower mold cavities and use patch thermocouple probes to stick to the center of the upper and lower mold cavities to measure the temperature.
[0004] However, after testing according to the existing scheme, it was found that the temperature measurement was not accurate. Because the mold cavity is always in a heat dissipation state when the equipment is open, the measured temperature is different from the real temperature, which will have a serious impact on more accurate quantitative tests. At the same time, the equipment cannot be tested in mold closing, because after the mold is closed, the upper and lower molds of the two mold cavities are tightly fitted, and the thermocouple probe wire will be clamped off. At the same time, the temperature detection error will be greater after the thermocouple wire is strongly squeezed. Utility Model Content
[0005] The utility model provides a mold cavity temperature test probe for a rotorless vulcanizer to solve the above-mentioned technical problems, and specifically adopts the following technical solutions:

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0031] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
[0032] like Figure 1 The figure shows a schematic diagram of a cavity structure of a rotorless vulcanizer, which includes an upper mold body 100 and a lower mold body 200. The opposite parts between the upper mold body 100 and the lower mold body 200 are respectively provided with a raised upper mold cavity edge 101 and a lower mold cavity edge 201. When the upper and lower mold bodies are molded together, the upper mold cavity edge 101 and the lower mold cavity edge 201 are in contact and form a cavity 300 between the upper mold body 100 and the lower mold body 200. In addition, in the cavity 300, a plurality of shear grooves (not shown) are provided on the opposite surfaces of the upper mold body 100 and the lower mold body 200.
[0033] like Figure 2 and 3 As shown, the present application provides a cavity temperature test probe for a rotorless vulcanizer, which is used to detect the temperature in a cavity 300. The cavity temperature test probe for a rotorless vulcanizer comprises: a thermocouple 10, a detection body 20, an elastic seal 30 and a plurality of interlocking parts 40. Specifically, the detection body 20 is made of copper. The thermocouple 10 is in the shape of an elongated needle, i.e., a thermocouple 10 probe. The detection body 20 is disc-shaped, and the detection body 20 is made of metal. In the present application, preferably, an elongated receiving hole 21 for inserting the thermocouple 10 and partially accommodating the thermocouple 10 is opened on the side of the detection body 20. The elastic seal 30 is arranged around the outer edge of the detection body 20. It is preferably made of high temperature resistant rubber. In addition, a through hole 35 for passing the thermocouple 10 is provided at a position of the elastic seal 30 corresponding to the receiving hole 21 of the detection body 20. The elastic seal 30 is used to be placed between the upper mold cavity edge 101 and the lower mold cavity edge 201 when the upper mold body 100 and the lower mold body 200 are molded. In this way, the thermocouple 10 can be prevented from being pinched off, and the sealing of the mold cavity 300 can be maintained at the same time.
[0034] The thermocouple 10 passes through the through hole 35 and the receiving hole 21 to be installed on the detection body 20, and the end of the thermocouple 10 away from the detection body 20 is connected to the detection device through a wire. A plurality of interlocking parts 40 are provided on the upper and lower surfaces of the detection body 20. The detection body 20 is matched with the mold cavity 300 of the rotorless vulcanizer in shape, and the plurality of interlocking parts 40 are adapted to the shear grooves in the upper and lower mold bodies of the rotorless vulcanizer.
[0035] In the embodiment of the present application, the fitting part 40 is radially arranged on the upper and lower surfaces of the detection body 20 with the center of the detection body 20 as the center. Furthermore, the fitting part 40 includes a first fitting part 41 and a second fitting part 42 having a width greater than that of the first fitting part 41 .
[0036] When the mold is opened, the mold cavity temperature test probe for the rotorless vulcanizer is placed in the lower mold body 200. After the mold is closed, the detection body 20 is located in the mold cavity 300, and the elastic sealing member 30 is used to seal the mold cavity 300.
[0037] In the embodiment of the present application, the detection body 20 is disc-shaped, and the elastic seal 30 is an annular sealing ring. The cross section of the elastic seal 30 is circular. Specifically, the inner ring of the elastic seal 30 is provided with an annular adapting groove 31 adapted to the outer ring of the detection body 20. In the present application, the outer ring of the detection body 20 is relatively sharp, so the cross section of the adapting groove 31 is a triangle that matches the sharp outer ring of the detection body 20.
[0038] As a preferred embodiment, the elastic seal 30 comprises an upper seal 32, a middle seal 33 and a lower seal 34. The upper seal 32, the middle seal 33 and the lower seal 34 are sequentially stacked in the up and down direction to form a complete elastic seal 30, the hardness of the upper seal 32 and the lower seal 34 is less than the hardness of the middle seal 33, and the through hole 35 is located on the middle seal 33.
[0039] It is understandable that, in order to protect the thermocouple 10 passing through the elastic seal 30 as much as possible, the elastic seal 30 is configured to have a middle portion with higher hardness and upper and lower portions with lower hardness, and the thermocouple 10 only passes through the middle portion. In this way, the support and protection of the thermocouple 10 in the elastic seal 30 are further strengthened on the basis that the elastic seal 30 as a whole maintains elastic support and elastic sealing. In the present application, the upper seal 32 and the lower seal 34 are made of the same material and have the same hardness.
[0040] As a preferred embodiment, the adapting groove 31 is located on the middle seal 33. The adapting groove 31 is arranged on the middle portion of the middle seal 33 with higher hardness, which further improves the matching stability between the elastic seal 30 and the detection body 20.
[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
