Description

Technical Field

[0001] The utility model belongs to the technical field of thermocouple production, and particularly relates to a casting frame for a spliced thermocouple temperature measuring couple head. Background Technique

[0002] A thermocouple is a commonly used temperature measuring element in temperature measuring instruments. It directly measures temperature, converts the temperature signal into a thermal electromotive force signal, and converts it into the temperature of the measured medium through an electrical instrument (secondary instrument). The outer shapes of various thermocouples are often very different due to needs, but their basic structures are roughly the same, mainly including a temperature measuring couple head and an insulating paper tube, and the main body part of the temperature measuring couple head is formed by alloy casting.

[0003] At present, the casting of the main body part of the thermocouple temperature measuring couple head is usually to directly cast alloy melt in a mold and form it after cooling. Since the volume of the couple head is not large and the demand quantity is large, during the casting process, the action process has a high degree of repetition and is very frequent. Therefore, a device that can assist in completing the casting work of the main body part of the temperature measuring couple head of a batch of thermocouples is needed to improve production efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a casting frame for a spliced thermocouple temperature measuring couple head, aiming to solve the problem of low production efficiency in the rapid casting of thermocouple temperature measuring couple heads in the prior art.

[0005] To solve the above problems, the utility model adopts the following technical solutions:

[0006] A casting frame for a spliced thermocouple temperature measuring couple head, the cross-section of the casting mold of the thermocouple temperature measuring couple head is in a frustum shape, and the diameter of the bottom frustum section is smaller than that of the open-end frustum section. It includes a base and a plurality of mold placement frames that can be spliced on the base in sequence from bottom to top. Each mold placement frame includes a beam body, a plurality of strip-shaped shelf plates, and a plurality of diagonal braces. The lower end face of the beam body has positioning protrusions, and the upper end face of the beam body and the upper end face of the base have positioning grooves corresponding to the splicing of the positioning protrusions; the beam body is the same length as the base, and the plurality of shelf plates are arranged at intervals along the length direction of the beam body and one end is detachably connected to the side surface of the beam body; the plurality of diagonal braces correspond to the number of the shelf plates one by one and one end is detachably connected to the end of the lower end face of the shelf plate away from the beam body, and the other end is detachably connected to the side surface of the beam body to support the shelf plate; between any two adjacent shelf plates, a plurality of casting molds of thermocouple temperature measuring couple heads can be placed along the length direction of the shelf plate.

[0007] The beneficial effects of the present utility model are as follows: A casting rack for the casting production of a spliced thermocouple temperature-measuring couple head is provided. It adopts a design with multiple mold placement racks forming a multi-layer structure, which are sequentially spliced on the base from bottom to top. Each mold placement rack has multiple shelf boards. The gap between two adjacent shelf boards can fit the frustum section below the casting mold for the production of thermocouple temperature-measuring couple heads, and the upper frustum section can abut against the plate surfaces of the two shelf boards. A whole column can be placed along the length direction of the shelf board. A column of casting molds for the production of thermocouple temperature-measuring couple heads can be placed in this way between any two adjacent shelf boards, greatly improving the casting efficiency. After all the thermocouple temperature-measuring couple heads on the first layer are cast, the second layer is directly spliced on the mold placement rack to continue casting, and so on. Finally, the casting work of multiple layers and multiple columns of thermocouple temperature-measuring couple heads is completed on one casting rack. The completely cast molds can be directly placed between the shelf boards to wait for cooling, without affecting the casting of new thermocouple temperature-measuring couple heads. In addition to improving the casting efficiency, it also greatly saves space.

[0008] Further, it further includes a fan mounting rack. The fan mounting rack is located below the shelf board, and one side of it is aligned with the side surface of the base and is detachably connected. A cooling fan is installed in the fan mounting rack, and the air outlet end of the cooling fan is arranged towards the upper shelf board.

[0009] A further beneficial effect of the present utility model is that by arranging a fan mounting rack and a fan below the shelf board, the cooling speed after the casting of the thermocouple temperature-measuring couple head is further accelerated, the production efficiency is improved. At the same time, the frame at the bottom can balance the problem of too high center of gravity formed by the sequential stacking of multiple-layer mold placement racks. The fan mounting rack can effectively avoid the situation of the device tipping over due to the increasing height through its own area and mass.

[0010] Further, it further includes multiple support rods and multiple support platforms. The multiple support rods are arranged at intervals corresponding to the number of shelf boards on the mold placement rack and are aligned with the shelf board intervals on the side of the fan mounting rack away from the base, and the lower ends are fixedly connected to the fan mounting rack; the multiple support platforms are respectively arranged along the length direction of each support rod corresponding to the shelf boards of each layer of the mold placement rack, and the lower end surfaces of each layer of shelf boards can abut against the upper end surfaces of the support platforms.

[0011] A further beneficial effect of the present utility model is that it further improves the support structure of the shelf board. Multiple vertical support rods are arranged on the side away from the shelf board, and support sleeves are arranged at intervals on the support rods for the end of the shelf board away from the beam body to lap. This prevents the situation that the end away from the connection point bends and deflects downward due to gravity because the shelf board is relatively long.

[0012] Further, in the middle of one end of the shelf board away from the beam body, there is a slot for setting the diameter of the support rod. The slots of each shelf board are inserted on the rod body of the corresponding support rod, and the lower end surface of the shelf board abuts against the upper end surface of the support platform.

[0013] A further beneficial effect of the present utility model is that: the support structure of the shelf board is further improved. An insertion slot is opened at one end of the shelf board close to the support rod to help the shelf board quickly position with the support rod. And due to the existence of the insertion slot, the part of the shelf board close to the support rod that can coincide with the support platform on the support rod becomes more, which is more conducive to the abutting effect of the support platform on the lower end surface of the shelf board.

[0014] Further, it further includes a counterweight mounting frame. The counterweight mounting frame is located on one side of the base away from the fan mounting frame and is detachably connected to the side surface of the base. The counterweight mounting frame can be assembled with counterweights of different weights to lower the center of gravity of the device.

[0015] A further beneficial effect of the present utility model is that: by setting the counterweight, the device is further prevented from tipping over, and the counterweight is arranged on the side away from the orientation of the shelf board and can balance with a large number of shelf boards, playing the role of lowering the center of gravity again.

[0016] Further, one end of the shelf board close to the beam body has a right-angle bending part. The right-angle bending part of the shelf board fits against the beam body and is bolted to it. One end of the diagonal brace passes through the right-angle bending part and is bolted to the beam body.

[0017] A further beneficial effect of the present utility model is that: by designing the right-angle bending here, it can assist in installing the shelf board on the beam body, giving a larger contact area between the shelf board and the beam body, and using multiple bolts for fixation. At the same time, one end of the diagonal brace is bolted to the lower end surface of the shelf board, and the other end passes through the right-angle bending part and is bolted to the beam body to assist in supporting the inclination angle of the shelf board.

[0018] Further, the mold placement rack further includes a plurality of strip-shaped positioning blocks. The number of the plurality of positioning blocks corresponds to the number of the shelf boards one by one. Along the length direction of the middle of the surface of each shelf board, there are a plurality of card slots. The lower end surface of the positioning block is provided with a hook adapted to be snap-fitted with the card slot. The width of the positioning block is smaller than the width of the shelf board. The side surfaces of the casting molds are abutted between any two adjacent positioning blocks to position the casting molds.

[0019] A further beneficial effect of the present utility model is that: by setting the positioning blocks, it can help the casting module of the thermocouple temperature measuring probe quickly position between two shelf boards, and slide in turn along the gap formed by the side edges of the two shelf boards, and finally quickly form a row of molds hanging on the mold placement rack.

[0020] Further, a traction part is provided on a side surface of the beam body away from the shelf board, and the traction part can be connected to a handling device.

[0021] A further beneficial effect of the present utility model is that the construction of the multi-layer mold placement rack is completed through the cooperation of the traction part and the handling device. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] As Figures 1-4 described, the present utility model provides a casting rack for a spliced thermocouple temperature measuring couple head, which is used for casting the main body part of the temperature measuring couple head of a fast thermocouple. The cross-section of a single temperature measuring couple head casting mold is in a frustum shape and consists of two frustum sections with different diameters. The casting rack provided by the present utility model is used to place multiple such molds, so as to carry out batch casting production operations of thermocouple temperature measuring couple heads.

[0031] Specifically, the casting rack for the spliced thermocouple temperature measuring couple head provided by the present utility model mainly includes a base 1 and a plurality of mold placement racks 2 that can be spliced on the base 1 in sequence from bottom to top. Each mold placement rack 2 includes a beam body 210, a plurality of strip-shaped rack plates 220, and a plurality of diagonal braces 230. The beam body 210 is a rectangular thick plate. The surfaces defined by the length and height of the beam body 210 are defined as the upper and lower end faces. The surface defined by the length and width is used to install the rack plates 220. There are positioning protrusions on the lower end face of the beam body 210, and there are positioning grooves corresponding to the positioning protrusions on the upper end face of the beam body 210 and the upper end face of the base 1. The beam body 210 is of the same length as the base 1. When splicing, it starts directly from the upper end face of the base 1. The shapes of the positioning protrusions and positioning grooves are not limited, as long as they can be spliced upward in sequence based on the base 1. In this embodiment, the shape of the positioning protrusion is a flat and long regular "convex" shape, and the shape of the positioning groove is adapted to it. When splicing, according to the actual specifications of the mold placement rack 2, it is necessary to align the positioning protrusions and positioning grooves of two mold placement racks 2 with the help of manpower or handling equipment, and then slowly push them in to complete the splicing. The plurality of rack plates 220 are arranged horizontally and at intervals along the length direction of the beam body 210, and one end is detachably connected to the installation surface of the beam body 210. The plurality of diagonal braces 230 correspond to the number of the rack plates 220 one by one, and one end is detachably connected to the end of the lower end face of the rack plate 220 away from the beam body 210, and the other end is detachably connected to the installation surface of the beam body 210 to support the rack plate 220 obliquely. After the rack plates 220 are installed, there is a gap between any two adjacent rack plates 220. The single molds for casting a plurality of thermocouple temperature measuring couple heads can be placed in the gap in sequence. The small-diameter frustum section is located in the middle of the gap, and the large-diameter frustum section is placed on the plate surfaces of the two rack plates 220 to complete the placement.

[0032] The present utility model adopts the design of forming a multi-layer structure with a plurality of mold placement racks 2, which are spliced on the base 1 in sequence from bottom to top. And each mold placement rack 2 has a plurality of rack plates 220. The gap between two adjacent rack plates 220 can be adapted to the frustum section below the casting mold for the thermocouple temperature measuring couple head, and the upper frustum section can be abutted against the plate surfaces of the two rack plates 220, and a whole row can be placed along the length direction of the rack plates 220. A row of casting molds for the thermocouple temperature measuring couple head can be placed in this way between any two adjacent rack plates 220, which greatly improves the casting efficiency. After all the thermocouple temperature measuring couple heads in the first layer are cast, the second layer can be directly spliced on the basis of the original mold placement rack 2 to continue casting, and so on. Finally, the casting work of multiple layers and multiple rows of thermocouple temperature measuring couple heads can be completed on one casting rack. The cast molds can be directly placed between the rack plates 220 to wait for cooling, which does not affect the casting of new thermocouple temperature measuring couple heads. And in addition to improving the casting efficiency, it also greatly saves space.

[0033] To further improve the technical solution, it further includes a fan mounting bracket 3. The top view of the fan mounting bracket 3 is a rectangular frame, where one set of side edges is as long as the base 1 and the beam body 210, and the other set of side edges is approximately as long as the shelf board 220. The fan mounting bracket 3 is arranged below the shelf board 220, and the side equal in length to the base 1 is bolted to the base 1. A cooling fan 4 is installed in the fan mounting bracket 3, and the air outlet end of the cooling fan is arranged towards the upper shelf board 220 to blow air on the numerous molds on the mold placement rack 2. Through the above technical solution, the utility model can further accelerate the cooling speed of the thermocouple temperature measuring tip after casting, improve production efficiency. At the same time, the fan mounting bracket 3 at the bottom can balance the problem of the excessively high center of gravity formed by the successive stacking of multiple layers of mold placement racks 2. The fan mounting bracket 3 can effectively avoid the situation of the device tipping over due to the increasing height through its own area and mass.

[0034] To further improve the technical solution, it further includes multiple support rods 5 and multiple support platforms 6. The multiple support rods 5 are successively installed on the side of the fan mounting bracket 3 away from the beam body 210, and the quantity corresponds to that of each layer of shelf board 220. The multiple support platforms 6 are respectively installed on the support rods 5 along the height direction of each support rod 5, and the quantity corresponds to the number of layers of the mold placement rack 2, ensuring that the lower end surface of each shelf board 220 of each layer can abut against the upper end surface of the support platform 6. Through the above technical solution, the utility model can prevent the situation that the shelf board 220 bends and deflects downward due to gravity at the point away from its connection point with the beam body 210 because the shelf board 220 is relatively long.

[0035] To further improve the technical solution, a slot 221 with a diameter equal to that of the support rod 5 is provided in the middle of the end of the shelf board 220 away from the beam body 210. The slot 221 of each shelf board 220 is inserted into the rod body of the corresponding support rod 5, and the lower end surface of the shelf board 220 abuts against the upper end surface of the support platform 6. By providing a plug-in slot at the end of the shelf board 220 close to the support rod 5, the utility model can help the shelf board 220 to be quickly positioned with the support rod 5. And due to the existence of the slot 221, the part where the end of the shelf board 220 close to the support rod 5 can coincide with the support platform 6 on the support rod 5 becomes larger, which is more conducive to the abutting effect of the support platform 6 on the lower end surface of the shelf board 220.

[0036] To further improve the technical solution, it further includes a counterweight mounting bracket 7. The counterweight mounting bracket 7 is located on the side of the base 1 away from the fan mounting bracket 3 and is bolted to the side surface of the base 1. The counterweight mounting bracket 7 can be assembled with counterweights of different weights to lower the center of gravity of the device. Specifically, the form and weight of the counterweights are not limited. By setting the counterweights, the device is further prevented from tipping over, and the counterweights set on the side away from the direction of the shelf board 220 can balance a large number of shelf boards 220, playing the role of lowering the center of gravity again.

[0037] To further improve the technical solution, the shelf plate 220 is specifically a right-angled bent plate. One end of the shelf plate 220 close to the beam body 210 has a right-angled bending part. The right-angled bending part of the shelf plate 220 fits against the beam body 210 and is connected to the beam body 210 by bolts. One end of the diagonal brace 230 is bolted to the lower end face of the shelf plate 220, and the other end passes through the right-angled bending part and is bolted to the beam body 210. By designing the right-angled bending at this place, it can assist in installing the shelf plate 220 on the beam body 210, giving a larger contact area between the shelf plate 220 and the beam body 210, and using multiple bolts to complete the fixation. At the same time, one end of the diagonal brace 230 is bolted to the lower end face of the shelf plate 220, and the other end passes through the right-angled bending part and is bolted to the beam body 210. Through the above technical solution, the utility model uses the diagonal brace 230 and the shelf plate 220 to form a stable triangular support, further improving the stability of the device.

[0038] To further improve the technical solution, each shelf plate 220 is provided with a positioning block 240. Specifically, a plurality of card slots 222 are provided along the length direction in the middle of the plate surface of each shelf plate 220. The lower end face of the positioning block 240 is provided with a hook 241 adapted to be snap-fitted with the card slot 222. The positioning block 240 is snap-fitted to the upper end face of the shelf plate 220 through the hook 241, and the width of the positioning block 240 is smaller than the width of the shelf plate 220. Any two adjacent positioning blocks 240 abut against the side surface of the casting mold to position the casting mold. By providing the positioning block 240, it can help the casting module of the thermocouple temperature measuring probe to be quickly positioned between the two shelf plates 220, and slide in turn along the gap formed by the sides of the two shelf plates 220, and finally quickly form a row of molds hanging on the mold placement rack 2. Specifically, the cross-section of the positioning block 240 is triangular, and the width of the bottom surface of the triangle can be adjusted and replaced while ensuring that it is smaller than the width of the shelf plate 220 to adapt to casting molds of different sizes.

[0039] To further improve the technical solution, a traction part is provided on the side surface of the beam body 210 away from the shelf plate 220. The traction part can be connected to handling equipment, and the construction of the multi-layer mold placement rack 2 is completed through the cooperation of the traction part and the handling equipment.

[0040] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and purpose of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
