A split quick-detachable hardware mold structure

Abstract

The utility model discloses a split quick-detachable hardware mold structure, which belongs to the technical field of hardware molds, and comprises an upper mold plate and a lower mold plate which are arranged relatively one above and one below. A hardware mold upper body and a hardware mold lower body are movably arranged below the upper mold plate and above the lower mold plate, respectively, and the hardware mold upper body and the hardware mold lower body are used in coordination with each other. By arranging the upper mold plate, the lower mold plate, the hardware mold upper body, the hardware mold lower body and a movable L-shaped slot for coordinated use, a traditional integral hardware mold is divided into several parts, and the weight is distributed, so that a single person can operate and use it, thereby avoiding the problem that the traditional hardware mold is too heavy and requires multiple people to lift it for installation, and the safety is improved. The movable L-shaped slot can be adjusted in position and locked, and the size can be changed by disassembling the movable L-shaped slot for different products. When opening the mold, only the upper and lower bodies of the hardware mold need to be opened, thereby effectively reducing the production cost.

Description

Technical Field

[0001] The utility model belongs to the technical field of hardware molds, and in particular relates to a split quick-detachable hardware mold structure. Background Art

[0002] When processing a product, if the product requires a CPK greater than 1.33, a flat knife is used and an ordinary etching mold cannot punch holes, resulting in the CPK not being met. The mold needs to be made using a hardware mold. The positioning holes punched by the hardware mold are fully broken holes without extrusion, making the positioning more accurate, thereby ensuring that the CPK is greater than 1.33. Hardware molds are especially preferred as the main molds during mass production. However, the existing hardware molds are large in size and heavy in weight. They are an integrated design that cannot be carried by personnel. Multiple people are required for installation and disassembly, posing a greater safety hazard. In addition, the overall design cost of the mold is high, and the mold cannot be reused after it is scrapped. Utility Model Content

[0014] As a preferred embodiment, a limiting slide bar is fixed on the surface of one of the two blocking plates at the same horizontal position, and a limiting slide groove for sliding the limiting slide bar is provided on the side of the other blocking plate.

[0015] By adopting the above solution, the limiting slide bar and the limiting slide groove are used together to support the blocking plate and prevent the blocking plate from shaking.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The split quick-detachable hardware mold structure is used in conjunction with an upper mold plate, a lower mold plate, an upper main body of the hardware mold, a lower main body of the hardware mold and a movable L-shaped slot, which divides the traditional integral hardware mold into several parts, distributes the weight, and can be operated and used by a single person, thereby avoiding the problem that the traditional hardware mold is too heavy and requires multiple people to lift it for installation, and the safety is improved. The movable L-shaped slot can be adjusted and locked in position, and the size can be changed for different products by disassembling the movable L-shaped slot. When opening the mold, only the upper and lower main bodies of the hardware mold need to be opened, effectively reducing production costs. BRIEF DESCRIPTION OF THE DRAWINGS
