Subsurface type feeding mold cavity plate

Abstract

The invention discloses a subsurface type feeding mold cavity plate which comprises a cuboid mold cavity plate body. A transverse runner is arranged in the middle of the upper end face of the mold cavity plate body. Two insert cavities in bilateral symmetry are formed in the mold cavity plate body and located in the left side and the right side of the transverse runner. Two subsurface type feeding openings in bilateral symmetry are further formed in the mold cavity plate body and enable the insert cavities in the left side and the right side to communicate with the transverse runner correspondingly. A plurality of locating pin holes are further formed in the mold cavity plate body. According to the subsurface type feeding mold cavity plate, the insert cavities in the middle are designed to be crescent and matched with crescent inserts, and therefore the bumping probability of the inserts during assembly can be lowered to the maximum extent, and mounting and demounting can be facilitated; and slow wire cutting machining is adopted for the insert cavities in the middle of the mold cavity plate, and the mold cavity plate, a front mold core plate and a rear mold core plate are subjected to slow wire cutting machining in place at the same time after being located by locating pins, wherein the front mold core plate and the rear mold core plate are matched with the mold cavity plate; and assembly errors are effectively avoided, and the precision of the mold cavity plate can be improved remarkably.

Description

technical field [0001] The invention relates to the structural technical field of plastic product molds, in particular to latent feeding cavity plates. Background technique [0002] With the continuous improvement of technology and the rapid development of the plastic product industry, the diversified structure of various plastic parts is becoming more and more complex, the quality requirements are becoming more and more stringent, the requirements for the plastic product industry are getting higher and higher, and the competition is also increasing. The more intense it is, how to ensure that there are no abnormalities in the production process of similar plastic products, and to maximize the effective and stable production cycle of product processing. The core combination of the existing mold generally includes the front core plate, the cavity plate and the rear core plate arranged in sequence from bottom to bottom, and the product model cavity is formed after the insert is...
