Problems solved by technology
[0003] The electromagnetic relay is a kind of relay, and the electromagnetic relay includes an electromagnetic coil. In the manufacturing process of the electromagnetic coil, the coil frame needs to be manufactured first, and then the wire is wound on the outside of the coil frame. Due to the complex shape and structure of the coil frame, the prior art Zhongda first uses molds to manufacture the main body model of the coil bobbin, and then uses an external lathe to perform operations such as drilling and cutting the main body model until a complete coil bobbin is obtained; the manufacturing process of the coil bobbin in the prior art is complicated. Low manufacturing efficiency and high processing costs

Embodiment Construction
[0031] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention.
[0032] see Figure 1 to Figure 3 As shown, a relay coil frame injection mold of the present invention includes a first template 1, a second template 2 detachably connected to the first template 1, and a second template 2 slidingly arranged between the first template 1 and the second template 2. The three templates 3 and the fourth template 4, the sliding direction of the third template 3 and the sliding direction of the fourth template 4 are collinearly arranged, the third template 3 and the fourth template 4 slide towards each other or in the direction of moving away from each other, the third template 3. The sides of the fourth template 4 that are close to each other are used to i...

The invention relates to the technical field of molds and particularly discloses a relay coil skeleton injection mold. The relay coil skeleton injection mold comprises a first template, a second template detachably connected to the first template, and third and fourth templates sliding between the first template and the second template. The third and fourth templates can slide toward each other oraway from each other. The first, second, third and fourth templates form a mold cavity. The third and fourth templates are respectively connected to first and second mold sheets extending into the mold cavity. The first or second template is provided with two architrave needles extending into the mold cavity. The two architrave needles respectively press against the first and second mold sheets.Through one-step injection molding, the coil skeleton is prepared without an injection molding coil skeleton and the coil skeleton is drilled through a tool so that the manufacturing efficiency of thecoil skeleton is improved and the processing cost of the coil skeleton is reduced.
Description
technical field [0001] The invention relates to the technical field of molds, and in particular discloses an injection mold for a relay coil skeleton. Background technique [0002] Relay (English name: relay) is an electrical control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity (excitation quantity) meets the specified requirements. The relay is actually a kind of "automatic switch" that uses a small current to control the operation of a large current, so it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit. [0003] The electromagnetic relay is a kind of relay, and the electromagnetic relay includes an electromagnetic coil. In the manufacturing process of the electromagnetic coil, the coil frame needs to be manufactured first, and then the wire is wound on the outside of the coil frame. D...
