CN202824534U - Device used for replacing mold core - Google Patents

Abstract

The utility model discloses a device used for replacing a mold core. The device used for replacing the mold core comprises a screw and a T-shaped rod. The device used for replacing the mold core further comprises an iron tube, wherein the iron tube is arranged on a horizontal rod of the T-shaped rod in a sleeved mode. According to the device used for replacing the mold core, the iron tube is arranged on the horizontal rod of the T-shaped rod and used as a load-bearing block, and therefore stress is enabled to be uniform, the mold core can be pulled out quite easily, replacing time is saved, and therefore replacing efficiency of the mold core is further improved.

Description

Be used for changing the device of core

Technical field

The utility model relates to a kind of device, specifically a kind of device for changing core.

Background technology

Core is that when casting is in order to form the foundry goods internal structure, the core sand that often is made into by roughing sand and binding agent.In the core process, usually use T-shaped bar, leading portion welding screw behind the screw tightening core, knocks the montant of T-shaped bar with instruments such as hammers.This mode can not stressedly evenly between the lathe active and inactive mold, apart from little, be inconvenient to put to good use when special, and very bad taking-up core has reduced the efficient of changing.

Summary of the invention

For the problem that above-mentioned prior art exists, the utility model provides a kind of device for changing core, and is simple in structure,, further improve the quality of production of foundry goods.

To achieve these goals, the technical solution adopted in the utility model is: a kind of device for changing core, comprise screw and T-shaped bar, and also comprise iron pipe, iron pipe is enclosed within on the cross bar of T-shaped bar, can move around to change the position.

Further, the iron pipe outer surface arranges one deck rubber.

The utility model arranges iron pipe by the cross bar at T-shaped bar, uses iron pipe as force block, so that stressed even, be easy to core is extracted, save the replacing time, thereby further improved the efficient that core is changed.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Among the figure: 1, screw, 2, T-shaped bar, 3, iron pipe.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As shown in Figure 1: to achieve these goals, the technical solution adopted in the utility model is: a kind of device for changing core, comprise screw 1 and T-shaped bar 2, and also comprise iron pipe 3, iron pipe 3 is enclosed within on the cross bar of T-shaped bar 2, can move around to change the position.

In the course of the work, after screw 1 is tightened core, iron pipe 2 is set on the artificial cross bar by T-shaped bar 2 core is extracted.Because use iron pipe 3 as force block, so that stressed even, be easy to core is extracted, save the replacing time, thereby further improved the efficient that core is changed.Better operate for the handled easily personnel simultaneously, iron pipe 3 outer surfaces arrange one deck rubber.

Claims (2)

1. a device that is used for changing core comprises screw (1) and T-shaped bar (2), it is characterized in that also comprise iron pipe (3), described iron pipe (3) is enclosed within on the cross bar of T-shaped bar (2).

2. a kind of device for changing core according to claim 1 is characterized in that described iron pipe (3) outer surface arranges one deck rubber.
