Embodiment 1

[0023] A mold clamp used in conjunction with a split-type exothermic welding mold, including a movable fixed shaft (1), an upper mold (9), and a lower mold (11); the fixed shaft (1) is sleeved with two and the The fixed frame (2) that the fixed shaft (1) slides, the two fixed frames (2) are used to fix the upper mold (9) and the lower mold (11) respectively, and the two fixed frames (2) The upper fixed shaft (1) is also sleeved with a cover frame (4) that slides with the fixed shaft (1), and the two fixed frames (2) and the cover frame (4) are connected by bolts and the The fixed shaft (1) is fixedly connected, and at least two horizontal insertion pins (5) are provided on the two fixed frames (2), and the upper mold (9) and the lower mold (11) are provided with There are insertion holes (12) corresponding to at least two horizontal insertion pins (5), the upper mold (9) is spliced ​​by two components (13) that match each other, and the upper mold The insertion hole (12) of (...

Embodiment 2

[0025] On the basis of Embodiment 1, a cover plate (10) is fixedly connected to the cover frame (4), and the cover plate (10) is used to cover the upper surface of the upper mold (9). There is a reaction chamber for welding reaction on the upper surface of the upper mold (9). When the cover plate (10) is connected to the upper surface of the upper mold (9), the cover plate (10) covers the reaction chamber. When the reaction chamber reacts When it is violent, it avoids the ejection of the substance in the reaction chamber, thereby avoiding the safety accident in the welding process.

Embodiment 3

[0027] On the basis of Examples 1-2, the components ( 13 ) and lower mold ( 11 ) that are spliced ​​to form the upper mold ( 9 ) are made of carbonaceous refractory materials. The heat transfer coefficient of carbonaceous refractories is large, which is conducive to the firm connection of the interface of the welded workpiece, and when the exothermic welding mold is produced with carbonaceous refractories, the production cost is low, and usually constitutes the upper mold of the exothermic welding mold ( 9) The component (13) and the lower mold (11) are both pressure-formed in different molds, which can be mass-produced.

Abstract

The invention discloses a mould clamp matched with a split exothermic welding mould. The mould clamp comprises a fixed shaft, an upper mould and a lower mould; two fixing brackets which are connectedwith the fixed shaft in a sliding manner are connected with the fixed shaft in a sleeving manner; the two fixing brackets are respectively used for fixing the upper mould and the lower mould; the part, above the two fixing brackets, of the fixed shaft is also connected with a cover plate frame which is connected with the fixed shaft in a sliding manner in a sleeving manner; the two fixing bracketsand the cover plate frame are fixedly connected with the fixed shaft through bolts; at least two transverse plug pins are arranged on each of the two fixing brackets; plugging holes corresponding tothe at least two transverse plug pins are formed in each of the upper mould and the lower mould; the upper mould is formed by splicing two assemblies which are matched with each other; the plugging holes of the upper mould penetrate through the two assemblies which are matched with each other. The exothermic welding mould disclosed by the invention is convenient to clamp and operate; an operationcan be completed by only one person in a process; the labour cost is reduced.

Description

technical field [0001] The invention relates to the technical field of clamping equipment for exothermic welding molds, in particular to a mold clamp used in conjunction with split exothermic welding molds. Background technique [0002] Exothermic welding is a simple, high-efficiency, high-quality metal connection process. It uses the chemical reaction heat of metal compounds as a heat source, and through the overheated molten metal, directly or indirectly heats the work to form a certain amount in the cavity of a special mold. Fusion welded joints in shape, size, and engineering requirements. At present, exothermic welding has generally replaced the previous mechanical connection method between metals. [0003] Currently known mold clamps for exothermic welding are used in actual use, especially when it is necessary to fasten the mold clamps after being put into the workpiece, the operator must use both hands together to achieve this, and this often results in The welding...
