Abstract
The utility model discloses the shaping switching mechanism of a kind of shell mould, the drive unit comprising underframe and be arranged on underframe and bearing, rollover stand to be arranged on bearing and to be connected with drive unit by rotating shaft, shell mould is provided with above rollover stand, electric heating tube is provided with bottom shell mould, oil cylinder installing plate is fixedly connected with by stud in the below of rollover stand, hydraulic jack is installed with in the below of oil cylinder installing plate, the push rod of hydraulic jack is connected with supporting plate through oil cylinder installing plate, supporting plate is provided with the push rod slided up and down for promoting ejector pin of die set fixed head, ejector pin of die set fixed head is fixed with one group of ejector pin of die set inserted in shell mould die cavity.When adopting the utility model shell, whole type process processed is without the need to human contact's shell, and avoid the generation of scald accident, and shell dimensional accuracy easily controls, molding sand consumption is few, and mold cavity surface is smooth, greatly reduces hand labor intensity.
Description
Technical field
The utility model relates to the shaping switching mechanism of a kind of shell mould, belongs to Shell Casting Technology field.
Background technology
Shell Casting Technology be with the molding sand (sand in coating phenolic resin) that a kind of heat is hardened cover be heated to 180 ~ 280 DEG C metal form on, it is made to be hardened to shell (shell thickness is generally 6 ~ 12 millimeters), heating cure shell again, it is made to reach enough strength and stiffness, then by upper and lower two panels shell fixture clamping or after cementing with resin, can form casting mold without sandbox, therefore shell moulded casting is specially adapted to the foundry goods that production lot is comparatively large, dimension precision requirement is high, wall is thin and complex-shaped.But, self-hardening resin sand is often adopted to make die cavity by hand in prior art, because die cavity needs heating to make, scald accident is easily produced when therefore making by hand, and home built cavity dimension precision is difficult to control, molding sand consumption is large, and mold cavity surface is of low quality, and operative's labour intensity is large.
Summary of the invention
The purpose of this utility model is, provides the shaping switching mechanism of semi-automatic shell mould that simple, easy to operate, the processed type efficiency of a kind of structure is high, to overcome prior art deficiency.
The technical solution of the utility model: the shaping switching mechanism of a kind of shell mould, the drive unit comprising underframe and be arranged on underframe and bearing, rollover stand to be arranged on bearing and to be connected with drive unit by rotating shaft, shell mould is provided with above rollover stand, electric heating tube is provided with bottom shell mould, oil cylinder installing plate is fixedly connected with by stud in the below of rollover stand, hydraulic jack is installed with in the below of oil cylinder installing plate, the push rod of hydraulic jack is connected with supporting plate through oil cylinder installing plate, supporting plate is provided with the push rod slided up and down for promoting ejector pin of die set fixed head, ejector pin of die set fixed head is fixed with one group of ejector pin of die set inserted in shell mould die cavity.
Aforesaid supporting plate can slide up and down along lead.
Aforesaid drive unit is made up of motor and decelerator, and decelerator is connected with rotating shaft by shaft coupling.
Owing to adopting technique scheme, the utility model has the advantage of: the utility model can be done being controlled by drive unit rollover stand 180 ° and overturns back and forth, after the shell in shell mould is made, it is ejected from shell mould by ejector pin of die set after overturning 180 ° downwards by rollover stand, therefore, whole type process processed is without the need to human contact's shell, avoid the generation of scald accident, and shell dimensional accuracy easily controls, molding sand consumption is few, mold cavity surface is smooth, greatly reduces hand labor intensity.
