Embodiment
[0031] Example: such as Figure 1-5 As shown, the present invention provides a technical solution, a side cavity core-pulling device of an injection mold for a battery shell, comprising a lower mold 1. Both ends of the lower mold 1 are equipped with core-pulling blocks 2, and the top of the core-pulling block 2 is provided Guide hole 3, upper mold 4 is installed at the top of lower mold 1 through guide posts, and guide rods 5 are installed at both ends of the top surface of upper mold 4;
[0032] A lubrication assembly 6 is installed inside the guide rod 5, and the lubrication assembly 6 includes a receiving cavity 601, an oil outlet 602, a ball 603, a flexible plastic tube 604, a rubber plug 605, a deformation groove 606, a sealing plate 607 and a stud 608;
[0033] The accommodating cavity 601 is opened inside the guide rod 5. The accommodating cavity 601 is filled with lubricating oil to facilitate lubrication by the lubricating assembly 6. The inner wall of the accommodating ca...

The invention discloses a side concave hole core pulling device for a storage battery shell injection molding die. Core pulling blocks are installed at the two ends of a lower die. A lubricating assembly is installed in each guide rod. Oil outlet holes are evenly formed in the inner wall of each containing cavity. A flexible plastic pipe is placed at the bottom end of the interior of each containing cavity, and a deformation groove is formed in the top end of each rubber stopper. A cooling assembly is installed in each core pulling rod. A heat conduction pillar is installed in each cooling cavity. Water inlet holes are formed in the two side faces of each core pulling block. Before the side concave hole core pulling device is used, lubricating oil is injected into the containing cavities,when the guide rods enter guide holes to push the core pulling blocks to move, protruding balls on the outer sides of the guide rods are extruded, the lubricating oil can seep out from the oil outletholes at the moment, the contact positions of the guide holes and the guide rods are lubricated and are prevented from being abraded, the moving accuracy of the core pulling blocks is ensured, cold water is injected into the cooling cavities, the core pulling rods are cooled, and due to the fact that the contraction rate of the metal core pulling rods is smaller than that of injection molding products after the metal core pulling rods are heated and expands, the core pulling rods can be pulled out conveniently.
Description
Technical field [0001] The invention relates to the technical field of molds, in particular to a side recessed hole core-pulling device of an injection mold of a battery shell. Background technique [0002] Injection molding is a method of stirring the completely melted plastic material through a screw at a certain temperature and injecting it into the mold cavity with high pressure. After cooling and solidifying, the molded product is obtained. The core pulling mechanism is a common mechanism in injection molds, and the core pulling mechanism is mostly followed The upper mold moves together, and a positioning or guiding mechanism such as a guide block is used to ensure the accuracy of core pulling. In order to simplify the mold structure and reduce the mold space. [0003] The patent application number 201620398612.5 mentions "a side recessed hole core-pulling device for the battery shell injection mold". The patent directly forms the mold on the mold and adds a hole-pulling mecha...
