Description

Technical Field

[0001] The utility model relates to the technical field of cam production, in particular to a cam production device. Background Art

[0002] A cam production device is a device used to manufacture cams. A cam is a rotating component with a non-circular profile, which is often used to control mechanical movement. In the prior art, cams are generally produced by CNC machine tool processing and mold casting, among which mold casting has low production cost and higher efficiency.

[0003] A quick mold for cam production disclosed in Chinese patent announcement number (CN213134974U) includes a base plate, a first vertical plate and a second vertical plate are fixedly connected on both sides of the top of the base plate, a first mounting plate is fixedly connected between the bottom of the first vertical plate and the bottom of the second vertical plate, a lower mold base is fixedly connected to the middle of the top of the first mounting plate, and fixing holes are provided at the four corners of the top of the lower mold base. The utility model is a quick mold for cam production, which tightly fixes the upper mold base and the lower mold base through the engagement of the limit block with the slot and the engagement of the pin with the fixing hole, so as to avoid the loosening of the mold during the production process and cause poor product quality. The elastic force of the reset spring is used to accelerate the mold opening speed and reduce the product molding cycle. While ensuring the mold closing accuracy of the upper mold base and the lower mold base, the working efficiency of the mold is improved. The position of the upper mold base is limited by the engagement and fixation of the push handle and the I-shaped slot, which can facilitate production operation.

[0004] However, as in the above patent, there is still a problem of low efficiency in mold casting and demolding for cam production. For example, in the above patent, the position of the upper mold seat is limited by the clamping and fixing of the push handle and the I-shaped groove, which can facilitate production operations and facilitate the casting of the upper and lower molds. However, in this method, it is necessary to use auxiliary tools to remove the cam from the mold after the upper and lower molds are separated. The low mold removal efficiency of this method affects the cam processing efficiency. Utility Model Content
