Problems solved by technology
[0002] The pads required for epoxy dry-type transformers are generally molded parts (DMC). Since there are many non-standard products in the transformer, in actual production, the pads often cannot achieve universality, that is, it is necessary to re-build the mold to meet the product requirements. requirements, thereby increasing the manufacturing cost of the product
At the same time, since the transformer coil needs to be casted with epoxy resin insulating material, there are more or less residual materials after the coil is cast. When these residual materials cannot be used for other products, it will cause waste; The impact on the environment can increase the cost of materials

Embodiment
[0018] Such as figure 1 As shown, a cushion block pouring mold includes a bottom plate (1). The bottom plate (1) is provided with surrounding panels. The surrounding panels are divided into left and right panels (2) and front and rear panels (3). The first fastener ( 7) The bolts pass through the bottom plate (1) and are fixed to the left and right side panels (2), the left and right side panels (2) are fixed, and then the second fasteners (8) are bolted to the front and rear side panels (3). The left and right side panels ( 2) A catch ring (8) is also provided at both ends. The slots provided on the enclosure are inserted into the partitions (4). After the partitions (4) are installed, they should be knocked flat with a wooden hammer. The partitions (4) must be in contact with the bottom plate of the mold to prevent the spacers from being poured. Form a local connection. After the partition (4) is installed, install the chamfered plate (5) according to the slot arranged on th...

The invention discloses a heel block casting mold. The mold comprises a base plate. A surrounding plate is arranged around the base plate, and is divided into the left and right surrounding plates, and the front and rear surrounding plates. Isolation plates are inserted in the sockets on the surrounding plates. Angle plates are placed on the sockets of the isolation plates. The base plate is provided with welded positioning pins, which are located either in the mold cavity formed by the surrounding plate and the isolation plate or in the mold cavity formed by the surrounding plate, isolation plates and the angle plates. The mold can effectively use the epoxy resin leftover from the casting of transformer coil. The cast product can meet the requirement of the heel blocks for one transformer without the necessity of repeated replacement. At the same time the adjustment can be made based on the sizes of the heel blocks. The heel block casting mold applies the assembly structure with simple structure and convenient and flexible operation, thus further increasing the product types and the use rate of the mold, and effectively reducing the cost.
Description
Technical field [0001] The invention relates to auxiliary accessories of epoxy dry-type transformers, in particular to a cushion block pouring mold used on epoxy dry-type transformers. Background technique [0002] The spacers required for epoxy dry-type transformers are generally molded parts (DMC). Since there are many non-standard products in the transformer, in actual production, the spacers often cannot achieve versatility, that is, the mold needs to be rebuilt to meet the product Requirements, thereby increasing the manufacturing cost of the product. At the same time, because the transformer coil needs to be molded with epoxy resin insulation material, there is more or less residual material after the coil is cast. When the residual material cannot be used for other products, it will cause waste; the wasted resin residual material is not only given to The impact of the environment can increase the cost of materials. In order to further reduce costs and increase efficiency...
