Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a hot pressing mold for an insulating cover plate. Background Art

[0002] The insulating cover is an important component of lithium batteries. It is mainly used to prevent the single cell from leaking or being damaged, causing short circuit or insulation problems on the metal conductive material of the entire battery. Traditional insulating covers are formed by negative pressure suction molding. This process is complicated and requires multiple steps to form. Making small batches of products will cause serious waste of cost and manpower. In order to reduce costs, hot pressing process is used for one-time molding, so a hot pressing mold is designed to solve this problem. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a hot pressing mold for an insulating cover plate, which has a reasonable structural design, low cost, adopts a hot pressing process for one-time molding, and is highly practical.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: an insulating cover plate hot pressing mold, including a hot pressing upper mold, a hot pressing lower mold, guide holes, product limiting columns, product pressing blocks and guide columns. The hot pressing upper mold and the hot pressing lower mold cooperate to form a mold cavity for placing the hot pressing product. The four corners of the hot pressing upper mold are provided with guide holes, which cooperate with the guide columns on the hot pressing lower mold. The three sides of the mold cavity of the hot pressing lower mold are provided with product limiting columns, which cooperate with the limiting holes on the hot pressing upper mold, and the product pressing blocks are arranged on the mold core of the hot pressing lower mold.

[0005] Preferably, the product pressing block matches the pressing block hole on the hot pressing upper die.

[0006] Preferably, the hot-pressed product is made of PC material.

[0007] Preferably, the hot pressing upper die and the hot pressing lower die are made of 45# steel.

[0008] Beneficial effects of the utility model: the plastic blister mold of the utility model is mainly composed of an upper mold and a lower mold, and the mold cavities of the upper mold and the lower mold are consistent with the final product. The mold structure is reasonably designed, the cost is low, the hot pressing process is used for one-time molding, and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0014] Reference Figure 1-3 , this specific implementation adopts the following technical scheme: an insulating cover plate hot pressing mold, including a hot pressing upper mold 1, a hot pressing lower mold 2, a guide hole 3, a product limiting column 4, a product pressing block 5 and a guide column 6. The hot pressing upper mold 1 and the hot pressing lower mold 2 cooperate to form a mold cavity for placing a hot pressing product 7. The four corners of the hot pressing upper mold 1 are provided with guide holes 3, and the guide holes 3 cooperate with the guide columns 6 on the hot pressing lower mold 2. The three sides of the mold cavity of the hot pressing lower mold 2 are provided with product limiting columns 4, and the product limiting columns 4 cooperate with the limiting holes 8 on the hot pressing upper mold 1. The product pressing block 5 is arranged on the mold core of the hot pressing lower mold 2.

[0015] It is worth noting that the product pressing block 5 is consistent with the pressing block hole 9 on the hot pressing upper mold 1.

[0016] It is worth noting that the hot-pressed product 7 is made of PC material.

[0017] In addition, the hot pressing upper die 1 and the hot pressing lower die 2 are made of 45# steel.

[0018] The hot pressing upper die of the hot pressing mold of this specific embodiment is provided with a guide hole, the hot pressing lower die is provided with a guide column and a limit column, and the lower die core is provided with a product pressing block, which is mainly used to prevent the product from warping after hot pressing (before hot pressing, the product's unfolded image is placed in the die cavity of the lower die, and one side of the product is inserted into the lower die pressing block to prevent it from slipping). The material of the hot pressing product is PC material with good physical properties, which meets the standards of the automotive industry, and the mold material is 45# steel.

[0019] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
