Description

Technical Field

[0001] The invention relates to a mold structure, in particular to an ejector-free rocker-rod ejector core-pulling mold mechanism. Background Art

[0002] Handheld temperature guns are mostly used to measure the surface temperature of people or objects, and their measurement method is mostly non-contact measurement.

[0003] The housing of the temperature measuring gun is an injection molded part and needs to be molded using an injection mold. Based on the principle of ergonomics, the measuring part and data display part of the temperature measuring gun are designed to be tilted relative to the handle, so the injection mold needs to be designed with core pulling mechanisms in multiple directions.

[0004] It is precisely because the inner cavity of the measuring part of the molded temperature measuring gun shell requires an oblique core pulling mechanism. After the parting surface is determined, this oblique core pulling mechanism is located at the lower part of the temperature measuring gun shell product. Therefore, it will interfere with the ejector pin often used in mold ejection, resulting in the inability to insert the ejector pin, and thus the ejection and blanking operation cannot be performed after molding and mold opening. Summary of the invention

[0005] The objects of the present invention are:

[0006] A pinless rocker ejector core-pulling mold mechanism is designed to realize the injection molding of the temperature measuring gun shell. When the ejector cannot be installed, the ejection of the temperature measuring gun shell product is realized through an alternative solution to ensure smooth mold opening and blanking.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] A pinless rocker arm ejection core-pulling mold mechanism, characterized in that it comprises a rocker arm, a side core-pulling top block, a lower insert block, an upper insert block, a side slide block and a side insert block, wherein the rocker arm, the side core-pulling top block, the lower insert block, the side slide block and the side insert block are all located in the lower mold core, a rocker arm seat is provided at the bottom end of the rocker arm, the side core-pulling top block is located at the top end of the rocker arm, a forming groove and a protrusion are provided on the side surface of the side core-pulling top block, and the rocker arm and the side core-pulling top block are arranged in a left-right symmetrical shape relative to the lower insert block; the lower insert block is located on the lower connecting block, and the lower connecting block is movably connected to the lower slide block seat; the upper insert block is located on the upper slide block seat, and the upper insert block is coaxially arranged with the lower insert block; the side insert block is located on the side slide block, and the side slide block is movably connected to the side slide block seat, and the side insert block and the side slide block correspond to the positions of the upper insert block and the lower insert block.

[0009] Furthermore, the swing rod is arranged vertically and a slanted wall and a bull's eye bearing are arranged on the side of the swing rod; the slanted wall is located on the side of the swing rod facing the lower insert, and the bull's eye bearing is distributed on the side of the swing rod facing away from the lower insert.

[0010] Furthermore, the bottom end of the rocker arm is hinged to a rocker arm seat, and the rocker arm seat is located on the ejector bottom plate.

[0011] Furthermore, the side core-pulling top block is arranged horizontally, the forming groove is specifically a groove and is located on the side of the side core-pulling top block facing the lower insert block, and the protrusions are located at both ends of the forming groove in the length direction.

[0012] Furthermore, the lower slider seat is located on the lower pad, the T-shaped slide groove on the lower connecting block is movably connected to the T-shaped bar on the lower slider seat, and the lower connecting block and the lower insert are both inclined.

[0033] The working principle of the present invention is: after the injection molding and cooling are completed, the mold opening and blanking operation begins;

[0034] Under the driving action of the injection molding machine, the upper mold part of the mold is separated from the lower mold part, and the upper mold part drives the upper slider seat 12 to move. Under the linkage action of the inclined T-shaped slide groove and the T-shaped bar, the upper insert 13 is separated from the lower insert 11, so that the core pulling on one side of the measuring part of the temperature measuring gun housing product part 17 is realized, and the upper core pulling is completed;

[0035] Under the driving action of the injection molding machine, the lower template and the lower pad are relatively separated to a specific gap, and under the linkage action of the inclined T-shaped slide groove and the T-shaped strip between the lower connecting block 10 and the lower slider seat 9, the lower insert 11 withdraws from the other side of the measuring part of the temperature measuring gun housing product 17 to realize the lower core pulling;

[0036] Under the linkage action of the inclined T-shaped slot and the T-shaped bar between the side slider 15 and the side slider seat 14, the side insert 16 and the side slider 15 move laterally, disengaging from the outer wall of the measuring part of the temperature measuring gun housing product 17, and realizing lateral core pulling;

[0037] The injection molding machine drives the ejector panel 3 and the ejector base plate 4 to lift upward, and the rocker seat 5 and the rocker 6 move upward together, thereby driving the side core-pulling ejector block 8 to lift the temperature measuring gun housing product 17 upward, so that the temperature measuring gun housing product 17 is separated from the lower mold core and various inserts and inserts; during the movement of the rocker 6, the bull's eye bearing 7 can reduce the friction force, and the inclined wall 61 can make the rocker 6 flip in the direction away from the temperature measuring gun housing product 17, so that the molding groove 81 and the protrusion 82 on the side core-pulling ejector block 8 are separated from the temperature measuring gun housing product 17, realizing side core pulling, and thus realizing the ejection of the temperature measuring gun housing product 17 without an ejector, ensuring smooth blanking.
