Through reasonable design and use of insert pins, the performance and efficiency of die-casting molds can be significantly improved. Since insert pins are more important in the use of molds, it is necessary to optimize the replacement of insert pins.

[0003] For example, a Chinese utility model patent with announcement number CN210755071 U discloses a die-casting mold for a converter housing for new energy vehicles. Although the above-mentioned prior art uses front and rear molds to die-cast the converter housing in one step, which not only has high surface accuracy and good product quality, but also improves production efficiency, when replacing the internal pins of the mold, the bottom plate must be removed first, and then the ejector plate and the ejector back plate must be removed to see the pins to be replaced. After finding them, the super-cold joint must be removed first, and then the screw sleeve and the support rod must be removed, and finally the pins must be taken out. The process is complicated, time-consuming, and labor-intensive. Such a one-time replacement will waste a lot of production time. Therefore, it is necessary to design a new energy vehicle mold that is easy to replace the pins. Utility Model Content

[0004] In order to solve the technical problem that the replacement of the insert pins of some die-casting molds is troublesome and affects production, the utility model provides a new energy vehicle mold with easy replacement of the insert pins.

[0006] Through the above technical solution, the pin assembly is installed on the shape assembly, and the pins in the pin assembly are easy to replace.

[0007] As a further improvement of the above scheme, a plurality of fixing grooves are opened on one side of the base plate, and the pin insertion assembly includes a pressing block arranged inside the fixing groove, a super-cold joint fixedly installed on the pressing block, and a pin insertion arranged on one side of the super-cold joint.

[0008] By using the above technical solution, the super-cold joint, the pressing block and the insert pin are combined together, so that the insert pin can be quickly replaced.

[0009] As a further improvement of the above solution, one end of the super-cold joint passes through the pressing block, the bottom plate, the ejector back plate and the ejector plate in sequence.

[0010] Through the above technical solution, the insert pin can be replaced by taking out the super-cold joint and the pressing block.

[0011] As a further improvement of the above solution, a support rod is sleeved on the outer surface of each of the super-cold joints.

[0012] Through the above technical solution, the support rod can protect the super-cold joint.

[0013] As a further improvement of the above solution, a limit plate is fixedly installed inside the mold shell, and a limit ring is sleeved on the outer surface of each support rod. The limit plate is fixedly sleeved with multiple limit rings.

[0014] Through the above technical solution, the limiting plate and the limiting ring can prevent the super-cold joint from deviating.

[0015] As a further improvement of the above solution, the outer surface of each of the inlay pins is covered with a protective sleeve with one end connected to the adjacent support rod.

[0016] Through the above technical solution, the protective cover can protect the inlay pin.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a shape component and a pin inserting component, and installs the pin inserting component on the shape component. When the pin inserting needs to be replaced, only the pressing block, the super-cold joint and the support rod of the pin inserting component need to be removed to replace the pin. This arrangement can avoid the need to remove the bottom plate, and then remove the ejector plate and the ejector back plate to see the pin to be replaced when replacing the pin in an ordinary mold. After finding the pin, first remove the super-cold joint, then remove the screw sleeve, the support rod, and finally take out the pin. The improvement saves replacement time and improves the production and processing efficiency of the mold. BRIEF DESCRIPTION OF THE DRAWINGS
