Description

Novel thimble assembly structure Technical Field The utility model relates to the technical field of thimble assembly structures, in particular to a novel thimble assembly structure. Background With the continuous development of the mechanical manufacturing and injection molding industries, injection molding technology is widely applied to the production of various precision parts, and advances towards high efficiency, high precision, high automation and intellectualization. The ejector pin assembly is taken as one of indispensable important parts in the injection mold, plays a key role in the demolding process of plastic products, and the quality and the production efficiency of the products are directly affected by the performance of the ejector pin assembly, so that the smooth operation of the whole production flow and the economic benefits of enterprises are related. However, the existing thimble assembly has limitations in original design, and the lack of a positioning structure between the thimble seat and the thimble cap leads to the fact that the thimble assembly is only suitable for single-needle operation and cannot meet the processing requirements of diversified chips. Accordingly, one skilled in the art would be able to provide a novel thimble assembly structure that solves the problems set forth in the background art discussed above. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides a novel thimble assembly structure, which solves the limitation of single needle use of a D510 thimble assembly and realizes accurate positioning and use of a plurality of thimbles by respectively adding positioning grooves and positioning pins on a thimble assembly base, a thimble seat and a thimble cap, thereby meeting the processing requirements of chips with various sizes, expanding the application range of Canon D510 core loading equipment and improving the universality of the equipment. In order to achieve the above purpose, the present utility model provides the following technical solutions: The novel thimble assembly structure comprises a base, a thimble seat and a thimble cap, wherein a base positioning pin is fixedly connected to one side of the outside of the base, a base positioning groove is formed in one side of the outside of the base, the thimble seat positioning pin is fixedly connected to one side of the outside of the thimble seat, and a plurality of thimble cap positioning grooves are formed in one side end face of the thimble cap; Through above-mentioned technical scheme, this structure has solved the limitation that D510 thimble subassembly single needle was used through increasing constant head tank and locating pin respectively on thimble subassembly base, thimble seat and thimble cap, has realized the accurate positioning and the use of many thimbles to satisfy the processing demand of multiple size chip, expanded the range of application of Canon D510 core feeding equipment, promoted the commonality of equipment. Further, one side of the outer part of the top needle seat is provided with a plurality of first through holes; Through above-mentioned technical scheme, can increase the heat radiating area of thimble seat, help the quick heat that the thimble produced in the high temperature operation in-process that looses, avoid the heat to gather and lead to thimble and subassembly damage around, improve thimble assembly's heat stability and life. Further, a plurality of second through holes are formed in the middle of one side end face of the thimble cap; through the technical scheme, the heat radiation performance of the thimble cap can be enhanced, a good ventilation and heat radiation channel is formed with the first through hole on the thimble seat, and the heat radiation effect of the whole thimble assembly is further optimized.
