Description

Technical Field

[0001] The invention relates to the technical field of explosive tool production equipment, in particular to an explosive tool core mold oiling machine. Background Art

[0002] Detonators, also known as booster charges, are used to detonate low-sensitivity explosives such as ammonium nitrate oil, slurry explosives, and emulsion explosives, as well as other explosives without detonator sensitivity. The detonator's initiation principle is that a detonator or detonating cord inserted into the detonator triggers the detonator, which then detonates the low-sensitivity explosive. The detonator amplifies the detonation wave.

[0003] In the process of producing detonators, detonator core molds are used. Figure 1 The figure shows a core mold for an explosive device, which includes a core mold base plate 100 and multiple core mold assemblies 200 disposed on the core mold base plate 100. The core mold assemblies 200 include a core mold base 2001 fixedly connected to the core mold base plate 100, a sheet 2002 that is liftably mounted on the core mold base 2001, and multiple core shafts 2003 disposed on the core mold base 2001. The core mold base plate 100 is provided with positioning holes 1001. After the explosive device is manufactured, the finished explosive device needs to be separated from the core mold. During the separation process, the core shafts are in close contact with the explosive agent in the explosive device, making it difficult to separate the core shafts. Summary of the Invention

[0004] The technical problem solved by the present invention is to provide a detonator core mold oiling machine which can make the detonator core mold easily demoulded.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a blasting tool core mold oiling machine, comprising:

[0006] frame;

[0007] A lifting assembly, the lifting assembly comprising a first lifting drive member, a lifting frame, a second lifting drive member, a lifting plate, a clamping and fixing mechanism, and a pressing plate, the first lifting drive member connecting the lifting frame and the frame, the second lifting drive member connecting the lifting frame and the lifting plate, the clamping and fixing mechanism being fixed on the lifting plate and clamping and fixing the pressing plate, the pressing plate being located below the lifting plate, elastic blocks being provided at both ends of the pressing plate, an unlocking mechanism cooperating with the elastic blocks being provided on the lifting frame, and a first avoidance hole being provided on the pressing plate;

[0008] A flip assembly, comprising a flip driver and a flip platform, wherein the flip driver connects the lifting frame and the flip platform, the flip platform is provided with a locking through hole for cooperating with the elastic block, and the flip platform is located below the pressure plate;

[0009] An oil tank is used to load demoulding oil. The oil tank is arranged on the frame and below the turning table. The top of the oil tank has an opening for inserting the core shaft of the detonator core mold.

[0010] The beneficial effect of the present invention is that the detonator core mold oiling machine can apply demolding oil to the core shaft of the detonator core mold, so that the core shaft of the detonator core mold can be more smoothly removed from the detonator finished product in the subsequent demolding process, which is beneficial to ensure the smoothness of the production of the detonator and guarantee the production efficiency and production yield of the detonator.
