Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning compressors, in particular to a die-casting mold for producing the cylinder block of an air-conditioning compressor. Background Technique

[0002] With the rapid development of the social economy and the continuous improvement of people's living standards, the number of automobiles in the country is increasing, and people's requirements for the comfort of automobiles are also getting higher and higher. As the main device for adjusting the temperature inside the vehicle, the air conditioner directly affects the comfort of the vehicle. As the core component of the automotive air-conditioning system, the compressor is the main component that determines the refrigeration effect of the air-conditioning system.

[0003] The cylinder block of the air-conditioning compressor is an important part of the compressor. As Figure 3 shown, the cylinder block of the air-conditioning compressor includes a cylinder block main body 23. The bottom of the cylinder block main body 23 has a main chamber 24. The periphery of the lower part of the cylinder block main body 23 is provided with a complex surrounding edge 26. One side of the upper part of the cylinder block main body 23 is also provided with a side hole position 25. Most conventional molds use two left and right core pulls to form half of the surrounding edge 26 respectively. A hole position protrusion is arranged on one of the core pulls to assist the side hole position 25. However, defects are likely to occur around the side hole position 25. How to make relatively small improvements on the basis of the existing mold to overcome the above problems is the top priority of consideration, and problems such as later maintenance and replacement also need to be considered. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a die-casting mold for producing the cylinder block of an air-conditioning compressor. With relatively small changes in the overall mold structure, the problems of sticking mold and deformation at the side hole position can be reduced; the flow splitter cone is designed into a movable structure that moves together with the slider seat, which can reduce the interference of the flow splitter cone on the demolding of the product and reduce the difficulty of demolding.

[0005] The technical solution adopted by the present utility model to solve its technical problems is: to provide a die-casting mold for producing an air-conditioning compressor cylinder block, including an upper die frame and a lower die frame. An upper die core and a lower die core stacked up and down are installed between the upper die frame and the lower die frame. A mold cavity is provided between the upper die core and the lower die core. A central insert column inserted into the mold cavity is provided in the middle of the upper end of the lower die core. A sliding block seat sliding horizontally is installed on each side of the lower die core at the upper end of the lower die frame. A semi-enclosed core-pulling block is installed at one end of the sliding block seat. A core-pulling oil cylinder is installed on each side of the lower die frame, and the core-pulling oil cylinder is connected to the corresponding sliding block seat. A driving block and a small oil cylinder for controlling the horizontal sliding of the driving block are installed on the right side of the upper die frame. A small side rod is clamped at the lower part of the driving block, and the small side rod is arranged horizontally. One end of the small side rod sequentially passes through the upper die frame, the sliding block seat and the upper die core and is provided with a hole protrusion inserted into the mold cavity. A cooling pipeline is arranged inside the small side rod. A joint and a retaining piece communicated with the cooling pipeline are installed on the side of the driving block, and the retaining piece presses one side of the joint. The retaining piece and the driving block are fixed by fasteners.

[0006] As a supplement to the technical solution of the present utility model, a flow dividing cone is installed at the upper end of the sliding block seat on the left side, and a charging cylinder sleeved outside the flow dividing cone is installed inside the upper part of the upper die frame.

[0007] As a supplement to the technical solution of the present utility model, a guide sleeve and a stop block are sequentially embedded and installed from left to right on the right side of the upper die core. The stop block and the upper die core are fixed by fasteners, and the end of the small side rod slides back and forth along the guide sleeve.

[0008] As a supplement to the technical solution of the present utility model, a T-shaped card slot is opened at the lower part of the driving block, and a clamping part matched with the T-shaped card slot is provided at the other end of the small side rod.

[0009] As a supplement to the technical solution of the present utility model, cut openings for the small side rod to pass through are opened at the upper ends of the sliding block seat and the core-pulling block on the right side.

[0010] As a supplement to the technical solution of the present utility model, the small oil cylinder and the upper die frame are connected by a plurality of support columns. Two guide columns are also arranged between the small oil cylinder and the upper die frame, and the guide columns are arranged horizontally. The driving block is sleeved on the two guide columns.

[0011] Beneficial effects: The utility model relates to a die-casting mold for producing an air-conditioning compressor cylinder block. Based on the original mold structure, as long as the hole protrusions on the right-side core-pulling block are cut off, holes are drilled at the positions of the original hole protrusions to form channels for small side rods to insert. A driving block and a small oil cylinder for controlling the horizontal sliding of the driving block are installed on the right side of the upper mold frame. The installation of the driving block and the small oil cylinder does not change the original structure of the upper mold frame, and only a few fixing holes need to be drilled. At the same time, openings for the small side rods to pass through are provided at the upper ends of the slider seat and the core-pulling block on the right side. With relatively small changes to the entire mold structure, the problems of mold sticking and deformation at the side hole positions can be reduced; the flow splitter cone is designed as a movable structure that moves together with the slider seat, which can reduce the interference of the flow splitter cone on the product demolding and reduce the demolding difficulty; a guide sleeve and a stop block are sequentially embedded and installed on the right side of the upper mold core from left to right. By the reciprocating friction between the guide sleeve and the small side rod, it is avoided that the small side rod directly contacts the upper mold core, and it is convenient to repair and replace the guide sleeve in the later stage, without the need to replace the entire upper mold core.

[0016] The following further elaborates the utility model in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and not to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of this application.

[0017] The embodiment of the utility model relates to a die-casting mold for producing an air-conditioning compressor cylinder block, as Figures 1-3As shown in the figure, it includes an upper die frame 1 and a lower die frame 2. An upper die core 3 and a lower die core 4 are stacked up and down between the upper die frame 1 and the lower die frame 2. A die cavity is provided between the upper die core 3 and the lower die core 4. A central insert post 5 inserted into the die cavity is provided in the middle of the upper end of the lower die core 4. On both sides of the lower die core 4 at the upper end of the lower die frame 2, a laterally sliding slider seat 12 is installed. One end of the slider seat 12 is equipped with a semi-enclosing core-pulling block 11. On both sides of the lower die frame 2, a core-pulling oil cylinder 13 is installed. The core-pulling oil cylinder 13 is connected to the corresponding slider seat 12. A driving block 8 and a small oil cylinder 9 for controlling the lateral sliding of the driving block 8 are installed on the right side of the upper die frame 1. A small side rod 6 is clamped under the driving block 8. The small side rod 6 is arranged horizontally. One end of the small side rod 6 passes through the upper die frame 1, the slider seat 12, and the upper die core 3 in sequence and is provided with a hole position protrusion 22 inserted into the die cavity. A cooling pipeline is arranged inside the small side rod 6. A joint 21 communicated with the cooling pipeline and a retaining piece 10 are installed on the side of the driving block 8. The retaining piece 10 presses one side of the joint 21. The retaining piece 10 and the driving block 8 are fixed by fasteners.

[0018] On the basis of the original die structure, as long as the hole position protrusion on the right-side core-pulling block is cut off, a channel for inserting the small side rod 6 is drilled at the position of the original hole position protrusion. A driving block 8 and a small oil cylinder 9 for controlling the lateral sliding of the driving block 8 are installed on the right side of the upper die frame 1. The small oil cylinder 9 and the upper die frame 1 are connected by a plurality of struts 20. Two guiding columns 7 are also arranged up and down between the small oil cylinder 9 and the upper die frame 1. The guiding columns 7 are arranged horizontally. The driving block 8 is sleeved on the two guiding columns 7. The installation of the driving block 8 and the small oil cylinder 9 does not change the original structure of the upper die frame 1. As long as several fixing holes are drilled. A notch 19 for the small side rod 6 to pass through is opened at the upper ends of the slider seat 12 and the core-pulling block 11 on the right side. The modification of the whole die structure is relatively small.

[0019] A flow splitter cone 14 is installed at the upper end of the slider seat 12 on the left side. A barrel 15 sleeved outside the flow splitter cone 14 is installed inside the upper part of the upper die frame 1; designing the flow splitter cone 14 into a movable structure that moves together with the slider seat 12 can reduce the interference of the flow splitter cone 14 on the product demolding and reduce the demolding difficulty.

[0020] As a preferred solution, a guiding sleeve 16 and a retaining block 17 are sequentially embedded and installed on the right side of the upper die core 3 from left to right. The retaining block 17 and the upper die core 3 are fixed by fasteners. The end of the small side rod 6 slides back and forth along the guiding sleeve 16; through the back-and-forth friction between the guiding sleeve 16 and the small side rod 6, it is avoided that the small side rod 6 directly contacts the upper die core 3. It is convenient to repair and replace the guiding sleeve 16 in the later stage, and there is no need to replace the whole upper die core 3.

[0021] As a preferred solution, a T-shaped card slot 18 is formed in the lower part of the driving block 8, and a clamping part is provided at the other end of the small side rod 6. The small side rod 6 is quickly connected to the driving block 8 through the cooperation of the clamping part and the T-shaped card slot 18.

[0022] When producing the cylinder block of an air conditioner compressor, the main chamber 24 is assisted in forming by the central inserted column 5, the peripheral edge 26 is assisted in forming by splicing two semi-surrounding core-pulling blocks 11, and the side hole positions 25 are assisted in forming by the small side rod 6. Then, the molten metal enters the mold from the barrel 15, is filled into the mold cavity through the diversion cone 14, and is kept under pressure in the mold by a die-casting machine. After the product is formed, the small oil cylinder 9 is first started, and the small oil cylinder 9 controls the small side rod 6 and the driving block 8 to move to the right, and the hole position protrusion 22 is separated from the formed side hole positions 25. The core-pulling block 11 on the right presses the cylinder block body 23, which can reduce the problems of sticking to the mold and deformation at the side hole positions 25. Then, the mold is opened, the upper mold frame 1 and the upper mold core 3 move upward, and the two core-pulling oil cylinders 13 respectively control the two core-pulling blocks 11 to open, and the end faces of the core-pulling oil cylinders 13 are separated from the formed peripheral edge 26.

[0023] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0024] For the convenience of description, spatial relative terms such as "above...", "above...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationship between a device or feature shown in the drawings and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the drawings of the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures" afterwards. Thus, the exemplary term "above..." can include two orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding explanations are made for the spatial relative descriptions used here.

[0025] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Without additional declaration, the above terms have no special meaning, so it should not be construed as a limitation on the protection scope of the present utility model.

[0026] The above has introduced in detail a die-casting mold for producing an air-conditioning compressor cylinder block provided by the present application. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation on the present application.
