Description

Technical Field

[0001] The utility model relates to the technical field of oil plug processing, in particular to an oil plug processing mould. Background Art

[0002] The oil plug is a fastener. The generally produced internal and external hexagonal screw plugs, pins, live bolts, welding screws, nuts, ring groove rivets, etc. are provided for the aerospace, aviation, navigation departments and automobile, locomotive and motorcycle manufacturers. With the continuous development of society, oil plugs have been widely used in various industries, and the corresponding processing molds are required in the production and processing of oil plugs.

[0003] After searching, the application with patent publication number CN209755935U discloses an oil plug processing mold, in which a bottom plate is provided at the center position of the top of the base, a top plate is provided above the bottom plate, a lower template is provided above the top plate, support blocks are provided on both sides of the bottom end of the lower template, a placement cavity is provided at the center position of the top of the lower template, a shaping cylinder is placed at the center position of the placement cavity, an upper template is provided above the lower template, and a plug column is provided at the center position of the bottom end of the upper template, which improves the accuracy of the mold when used and extends the service life of the mold.

[0004] However, due to the setting of the upper template and the lower template, after the oil plug is placed in the cavity and the molding cylinder for injection molding, the oil plug is parallel to the top surface of the upper template, which makes it inconvenient to remove the oil plug. It is easy to cause damage to the oil plug during removal. At the same time, since the upper template and the lower template can only produce one specification of oil plug, and the oil plug can be divided into hexagonal screw plug and hexagonal screw plug, the production has certain limitations and low practicality.

[0005] Therefore, we proposed an oil plug processing die. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides an oil plug processing die, which solves the problems that the prior device is inconvenient to remove the oil plug and has low practicality.

[0007] To achieve the above purpose, the utility model is implemented through the following technical solutions: an oil plug processing mold, comprising a base, four sets of electric telescopic rods are fixedly installed on the top surface of the base, and a top plate is fixedly installed on the top of the electric telescopic rod;

[0008] A lower mold is fixedly installed on the top surface of the base, an upper mold is fixedly installed on the bottom surface of the top plate, a lower mold cavity is opened on the top surface of the lower mold, an upper mold cavity is opened on the bottom surface of the upper mold, a cylinder is fixedly installed on the bottom of the lower mold cavity, a piston plate slidably connected to the lower mold cavity is sleeved on the output end of the cylinder, and a space formed between the top surface of the piston plate and the top surface of the upper mold cavity is an oil plug molding space;

[0009] The top surface of the piston plate is equipped with an external hexagonal stud, and a threaded hole A is opened on the top surface of the piston plate. A bolt A of matching specifications is fixedly installed on the bottom surface of the external hexagonal stud. The top surface of the upper mold cavity is equipped with an internal hexagonal stud in a relatively opposite position, and a bolt B is fixedly installed on the top surface of the internal hexagonal stud. The top surface of the upper mold cavity is opened with a threaded hole B of matching specifications.

[0010] Preferably, the top surface of the top plate is fixedly mounted with injection ports in opposite positions, and the top surface of the upper mold cavity is provided with four groups of injection holes in opposite positions and connected with the injection ports, which can improve the efficiency and uniformity of injection molding, thereby ensuring the quality of injection molding.

[0011] Preferably, the top surface of the lower mold and the bottom surface of the upper mold are equipped with sealing gaskets, which can improve the sealing between the lower mold and the upper mold.

[0012] Preferably, the sealing gasket is made of rubber material, so that the upper mold and the lower mold can be cushioned to prevent damage.

[0013] Preferably, the piston plate is made of high temperature resistant silicon carbide material, which can improve the high temperature resistance of the piston plate and prevent it from being deformed due to high temperature and affecting the effect of injection molding.

[0014] Preferably, the top surface of the piston plate is coated with an anti-adhesion layer, which makes it easier to remove the oil plug after injection molding.

[0015] 1. This oil plug processing mold is arranged by a cylinder, a piston plate and an electric telescopic rod. After the injection molding of the oil plug is completed, the electric telescopic rod first drives the upper mold to move upward, and then the cylinder drives the piston plate to move upward, thereby pushing the oil plug in the lower mold cavity upward, so that it is easy to take the oil plug out of the injection molding cavity, which is simple and convenient, and avoids damage to the oil plug when taking it out.

[0016] 2. At the same time, through the arrangement of the external hexagonal studs, internal hexagonal studs and bolts, according to the production needs, the external hexagonal studs and internal hexagonal studs can be freely installed on the top surface of the piston plate and the top surface of the upper mold cavity through the bolts and threaded holes, so that both external hexagonal stud-shaped oil plugs and internal hexagonal stud-shaped oil plugs can be produced, which is highly practical.
