Description

Technical Field

[0001] This utility model relates to the field of oil injection machine technology, and in particular to an external mold oil injection machine. Background Technology

[0002] Oiling the outer mold is a crucial step in mold lubrication, primarily used to reduce mold wear, prevent adhesion, improve product surface quality, and extend mold life. Existing oiling machines are large, complex in structure, and cumbersome to operate. Utility Model Content

[0003] This invention solves the problems in related technologies and proposes an external mold oil injection machine that simplifies the structure, reduces the volume, and enables oil injection into external molds.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: an external mold oil injection machine, comprising a cylinder, an oil injection barrel, an oil storage barrel, and an oil tank. The piston rod of the cylinder extends into the oil injection barrel and is connected to the piston in the oil injection barrel. The oil injection barrel and the oil storage barrel are connected through an oil supply pipe. A tee is installed on the oil supply pipe, and the tee is also connected to an oil outlet pipe. A first check valve is installed on the oil supply pipe between the tee and the oil injection barrel. The oil injection barrel is fixed to the oil tank and connected to the oil tank through an oil inlet pipe. A second check valve is installed on the oil inlet pipe.

[0005] As a preferred embodiment, a cover plate is also included, and the cylinder and the oil storage tank are fixed to the cover plate.

[0006] As a preferred embodiment, the oil filling barrel is mounted on the oil tank via a bracket.

[0007] As a preferred embodiment, the cylinder and the oil filling tank are connected by a connecting seat.

[0008] As a preferred embodiment, the top of the oil tank is provided with a protective cover, and both the cylinder and the oil storage tank are placed inside the protective cover.

[0009] Compared with existing technologies, the advantages of this invention are as follows: This invention uses a cylinder to draw oil from the oil tank into the oil filling tank, and then the oil is pushed down by the piston rod into the oil outlet pipe and the oil storage tank. Oil is then injected into the outer mold through the oil outlet pipe, while the oil in the storage tank can also be used to inject oil into the outer mold during the cylinder's oil extraction process, thus achieving uninterrupted oil injection. This invention simplifies the structure, reduces the overall size, and is easy to operate. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0014] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0015] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0016] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0017] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0018] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0019] like Figure 1As shown, an external mold oil injection machine includes a cylinder 1, an oil injection tank 2, an oil storage tank 3, and an oil tank 4. The piston rod of the cylinder 1 extends into the oil injection tank 2 and is connected to the piston 12 inside the oil injection tank 2. The oil injection tank 2 and the oil storage tank 3 are connected by an oil delivery pipeline, which includes a first oil delivery pipeline 801 and a second oil delivery pipeline 802. A tee 9 is installed between the first oil delivery pipeline 801 and the second oil delivery pipeline 802. Port C of the tee 9 is connected to the oil outlet pipe, port A of the tee 9 is connected to the first oil delivery pipeline 801, and port B of the tee 9 is connected to the second oil delivery pipeline 802. A first check valve is installed on the first oil delivery pipeline 801. The oil injection tank 2 is fixed to the oil tank 4 and is connected to the oil tank 4 through an oil inlet pipeline 11. A second check valve is installed on the oil inlet pipeline 11. When injecting oil, the second check valve is opened first. Furthermore, ports A, B, and C of the tee 9 are all open. When cylinder 1 operates, the piston rod of cylinder 1 pulls upward, causing piston 12 to move upward, thereby drawing oil from oil tank 4 into oil filling tank 2. Then, the first check valve opens and the second check valve closes. The piston rod of cylinder 1 pushes the piston downward, transporting the oil in oil filling tank 2 through the first oil delivery pipe 801 and ports A and C of tee 9 to the oil outlet pipe. Excess oil continues to be transported through port A of tee 9 and the second delivery pipe 802 to the oil storage tank 3 for storage. When the piston rod of cylinder 1 pulls upward, oil can be injected through the oil storage tank 3. At this time, the first check valve is closed, port A of tee 9 is closed, and ports B and C are open. Under the action of gravity, the oil in the oil storage tank 3 is transported through the second oil delivery pipe 802 to the oil outlet pipe, thereby achieving uninterrupted oil injection.

[0020] In one embodiment, in order to improve the stability of the oil storage tank 3, a cover plate 5 is also included, and both the cylinder 1 and the oil storage tank 3 are fixed to the cover plate 5 by bolts.

[0021] In one embodiment, the oil filling barrel 2 is mounted on the top of the oil tank 4 by a bracket 6. Specifically, the oil filling barrel 2 has mounting flanges at both the top and bottom. The bracket 6 is a cylindrical structure with mounting flanges at both the top and bottom. The bracket 6 is fitted around the outside of the oil filling barrel 2. The mounting flange at the bottom of the bracket 6 is fixed to the top of the oil tank 4 by bolts. The mounting flange at the top of the bracket 6 is fixed to the mounting flange at the bottom of the oil filling barrel 2 by bolts.

[0022] In one embodiment, the cylinder 1 and the oil filling tank 2 are connected by a connecting seat 10. The connecting seat 10 has mounting flanges at both the top and bottom. The upper mounting flange is fixedly connected to the cylinder 1 by bolts, and the lower mounting flange is fixed to the upper mounting flange of the oil filling tank 2 by bolts.

[0023] In one embodiment, a protective cover 7 is provided on the top of the oil tank 4, and the cylinder 1 and the oil storage tank 3 are both placed inside the protective cover 7 to protect the cylinder 1 and the oil storage tank 3 inside.

[0024] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
