Description

Technical Field

[0001] The utility model relates to a mould, in particular to a connector mould for agricultural equipment. Background Art

[0002] Figure 1 A connector for agricultural equipment is shown in FIG. 1 , comprising a main body 100 , wherein the main body 100 has two pipes 101 with an acute angle therebetween, and the pipes 101 have through holes 102 therein.

[0003] This product is very troublesome to demould due to the presence of two pipes. The conventional method is to set two plug rods on the mold and insert them into the pipes to form a through hole. When demoulding, the two plug rods also need to use a special driving mechanism to withdraw from the through hole. For this reason, a special driving mechanism is required for each plug rod, which makes the mold very complicated. Therefore, it is necessary to improve it. Summary of the invention

[0004] The utility model aims to provide a connector mould for agricultural equipment, and the mould structure is greatly simplified.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a connector mold for agricultural equipment, comprising an upper mold and a lower mold, a cavity formed by the upper mold and the lower mold after the mold is combined to form the outer wall of the connector, characterized in that: it also includes a guide mechanism, the guide mechanism includes a slider slidably connected to the lower mold, two plug rods are fixed on the slider, and a guide block is also fixed on the lower mold, one end of the plug rod passes through the guide block and then penetrates into the cavity to form a through hole in the pipeline, and also includes a guide rod, the top of the guide rod is connected to the upper mold, the bottom of the guide rod passes through the through hole on the slider and extends downward, and the upper part of the guide rod is inclined toward the center of the mold. When demolding, we pull the upper mold, and the upper mold moves upward, driving the guide rod to move upward. During the upward movement of the guide rod, since the upper part of the guide rod is inclined toward the center of the mold, the lower part of the guide rod is inclined toward the outside. Therefore, during the upward movement, the slider will be pulled outward, and the slider can drive the insertion rod to move outward and escape from the through hole to complete the demolding. During the process, the guide block plays a role in maintaining the movement direction of the insertion rod. This structure of the mold combines the outward movement of the guide rod with the opening action of the upper mold, reducing two mechanisms for driving the guide rod, greatly simplifying the mold structure, and also simplifying the mold opening process.

[0006] In the above technical solution, preferably, the mold forms two of the connecting parts at one time, and there are two guide mechanisms, which are arranged opposite to each other.

[0007] In the above technical solution, preferably, the upper mold includes a template and a fixed block fixed on the end surface of the template, and the upper part of the guide rod is arranged in the fixed block.

[0008] In the above technical solution, preferably, the fixed block is provided with a stepped hole, and the guide rod is divided into a first part with a larger diameter and a second part with a smaller diameter, the first part is arranged above the end with a larger diameter of the stepped hole, and the second part passes through the bottom of the end with a smaller diameter of the stepped hole. In this way, during the rising process of the upper mold, the guide rod will be blocked, driving the guide rod to move.

[0009] In the above technical solution, preferably, a pouring gate is provided on the upper mold.

[0010] The utility model has at least the following beneficial effects: the mold with this structure combines the outward movement of the guide rod into the upper mold opening action, reducing two mechanisms for driving the guide rod, greatly simplifying the mold structure, and also simplifying the mold opening process.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 2-5 A connector mold for agricultural equipment includes an upper mold 1 and a lower mold 2. The cavity formed by the upper mold 1 and the lower mold 2 after the mold is combined forms the outer wall of the connector 100. The mold molds two connectors 100 at one time.

[0018] The invention also comprises a guide mechanism 3, wherein there are two guide mechanisms, and the two guide mechanisms are arranged opposite to each other.

[0019] The guide mechanism 3 includes a slider 31 slidably connected to the lower mold 1, and two insertion rods 311 are fixed to the slider 31. A guide block 32 is also fixed to the lower mold 2, and one end of the insertion rod 311 passes through the guide block 32 and then penetrates into the mold cavity to form a through hole 102 in the pipeline 101.

[0020] It also includes a guide rod 33, the top of which is connected to the upper mold 1, and the bottom of the guide rod 33 passes through the through hole on the slider 31 and extends downward, and the upper part of the guide rod 33 is inclined toward the center of the mold.

[0021] The upper mold 1 includes a mold plate 11 and a fixing block 12 fixed on the end surface of the mold plate 11 , and the upper portion of the guide rod 33 is disposed in the fixing block 12 .

[0022] The fixed block 12 is provided with a stepped hole 121, and the guide rod 33 is divided into a first portion 331 with a larger diameter and a second portion 332 with a smaller diameter, wherein the first portion 331 is arranged above the end of the stepped hole with a larger diameter, and the second portion passes through the bottom of the end of the stepped hole with a smaller diameter. In this arrangement, the guide rod will be blocked during the ascending process of the upper die, driving the guide rod to move.

[0023] The upper mold 1 is provided with a pouring port 13 .

[0024] When demolding, we pull the upper mold, and the upper mold moves upward, driving the guide rod to move upward. During the upward movement of the guide rod, since the upper part of the guide rod is inclined toward the center of the mold, the lower part of the guide rod is inclined toward the outside. Therefore, during the upward movement, the slider will be pulled outward, and the slider can drive the insertion rod to move outward and escape from the through hole to complete the demolding. During the process, the guide block plays a role in maintaining the movement direction of the insertion rod. This structure of the mold combines the outward movement of the guide rod with the opening action of the upper mold, reducing two mechanisms for driving the guide rod, greatly simplifying the mold structure, and also simplifying the mold opening process.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
