Abstract

The invention relates to the technical field of molds, in particular to a mold frame of a mold. The mold frame comprises an upper mold body and a lower mold body. The middle of the upper mold body and the middle of the lower mold body are provided with opposite cavities correspondingly and both provided with positioning holes, and every two opposite positioning holes are internally provided with a positioning pin. Each positioning pin is of a hollow structure with an opening in one end, and a water groove is formed inside each positioning pin. The positioning pins include the water inlet positioning pins and the water outlet positioning pins. An upper opening and a lower opening are formed in the upper end and the lower end of the lateral surface of each positioning pin and communicate with the corresponding water groove. The upper mold body is provided with an upper water groove communicating with the upper openings of the water inlet positioning pins and the upper openings of the water outlet positioning pins. The lower mold body is provided with a lower water groove communicating with the lower openings of the water inlet positioning pins and the lower openings of the water outlet positioning pins. Each positioning pin is of the hollow structure with the opening in one end and communicates with the inner upper water groove and the inner lower water groove, so that a cooling system is effectively formed, and the cost is lowered.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a mold base of a mold. Background technique [0002] The mold is generally composed of a mold core and a mold frame. The mold frame includes an upper mold frame and a lower mold frame. The middle parts of the upper mold frame and the lower mold frame are respectively provided with recessed cavities. When the mold is working, sometimes it needs water cooling. , the current practice is to set up cooling tanks on the upper mold base and the lower mold base respectively. The design of the frame brings difficulty; and increases the manufacturing cost. Contents of the invention [0003] In order to solve the problem of difficult installation of the mold base cooling system in the prior art, the present invention provides a mold base which does not need to be additionally provided with water inlets and water outlets, thereby reducing its cost. [0004] The technical scheme adopted in ...
