Anti-sticking die structure for large-sized sliding block

Abstract

The invention discloses an anti-sticking die structure for a large-sized sliding block. The anti-sticking die structure comprises a die plate and the sliding block. The sliding block is movably mounted in a sliding block groove formed in the die plate. Sliding devices are arranged inside the die plate, and comprise pressing blocks, bearing pedestals, elastic parts and bottom surface bearings. The bearing pedestals are positioned at the tops of the pressing blocks. The elastic parts are mounted between the pressing blocks and the bearing pedestals. The bottom surface bearings are mounted on the bearing pedestals, and are matched with the bottom of the sliding block in a sliding manner. The sliding block is jacked up to be suspended on the die plate under the action of the elastic parts. A gap is reserved between one of the step surfaces on two sides of each bearing pedestal and the die plate. Sliding block steps are respectively formed on the two sides of the sliding block. Slide wedges positioned in the sliding block groove are respectively formed on two sides of the sliding block. A gap is reserved between each slide wedge and the sliding block. The anti-sticking die structure can solve the problem that the large-sized sliding block is stuck in the die plate. Besides, side bearings and step surface bearings are arranged on the slide wedges, so that the friction coefficients are further reduced, and the sliding smoothness of the large-sized sliding block on the die plate is improved.

Description

technical field [0001] The invention relates to the technical field of plastic molds, and more specifically relates to a large-scale slider anti-seize mold structure. Background technique [0002] In traditional moulds, oil grooves are provided at the bottom of the large slider, and the friction between the bottom of the large slider and the entire large-area plane on the formwork is face-to-face. Due to the heavy weight of the large slider, it is easy Lubricating oil and other conditions are stuck, which leads to unsmooth mold production and requires frequent maintenance. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects in the prior art, and provide a large-scale slider anti-seize mold structure. [0004] In order to achieve the above object, the present invention provides a large-scale slider anti-seize mold structure, including a template and a slider, the slider is movably installed in the slider groove ...
