Description

Technical Field

[0001] This utility model relates to the field of automotive parts die-casting mold technology, specifically a die-casting mold for a compressor cylinder head. Background Technology

[0002] The cylinder head of an automotive compressor is a crucial component in the thermal management system of new energy vehicles. Currently, it is generally formed using die-casting molds. The side of the cylinder head of an automotive compressor has multiple mounting holes and vent holes. Due to the limited internal space of the mold, it is difficult to utilize the space of the lower mold plate to set up two inclined core pulls corresponding to two forming cavities. Therefore, only one forming cavity can be set up at present, resulting in low processing efficiency. Utility Model Content

[0003] This utility model provides a die-casting mold for a compressor cylinder head, which can solve the technical problem that it is difficult to set two corresponding oblique core-pulling devices on the mold due to the location of the air vent of the compressor cylinder head.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a die-casting mold for a compressor cylinder head, comprising an upper mold plate and a lower mold plate arranged vertically. A first lower mold core and a second lower mold core are embedded side-by-side on the lower mold plate. A first upper mold core and a second upper mold core, respectively matching the first lower mold core and the second lower mold core, are embedded side-by-side on the upper mold plate. A forming cavity is formed between the first lower mold core and the first upper mold core, and between the second lower mold core and the second upper mold core. A forming slider is provided on the upper side of the lower mold plate, located on one side of the first lower mold core and the second lower mold core. A driving cylinder is installed on the rear side of the forming slider. A cylinder located on the inner side of the upper mold plate, above the forming slider, is installed on the upper side. The feeding plate matches the feeding channel on the upper template. A first inclined guide post core-pulling slider assembly is installed at both ends of the rear side of the forming slider. A second inclined guide post core-pulling slider assembly is obliquely arranged on the lower template on one side of the first lower mold core. A third inclined guide post core-pulling slider assembly is correspondingly installed on the lower template on both sides of the first and second lower mold cores. A fourth inclined guide post core-pulling slider assembly parallel to the second inclined guide post core-pulling slider assembly is embedded in the second lower mold core. By setting two pairs of lower mold cores and upper mold cores, two forming cavities are set. Simultaneously, the space between the lower template and the second lower mold core is utilized to set the inclined guide post core-pulling slider assembly, allowing for the simultaneous forming of two products with high processing efficiency.

[0005] Preferably, the first, second, third, and fourth inclined guide post core-pulling slider assemblies all include a sliding seat and a core-pulling slider disposed within the sliding seat. An inclined guide post is obliquely disposed within the core-pulling slider, and a forming core-pulling rod inserted into the forming mold cavity is disposed at the end of the core-pulling slider. When the upper mold plate and the lower mold plate are separated, the sliding seat will retract simultaneously, thereby achieving synchronous core pulling of the forming core-pulling rod.

[0006] Preferably, the feed plate and the forming slider form two branch flow channels and a central flow channel in the middle. The branch flow channels extend into the two forming cavities respectively, and the central flow channel is connected to the two forming cavities through the branch flow channels on both sides, so that the rapid feeding and forming of the two forming cavities can be realized simultaneously.

[0007] Preferably, a top plate is installed below the lower mold plate, and several ejector pins are arranged on the top plate and inserted vertically into the forming cavity, which can realize the ejection of products from the two forming cavities.

[0008] Preferably, the upper side of the lower template is provided with vacuum pump mounting slots on the sides of the first and second lower mold cores, respectively. A vacuum pump matching the corresponding exhaust block is installed in the vacuum pump mounting slot. The vacuum pump can be used to quickly evacuate the air in the molding cavity, reduce the air holes in the molded product in the molding cavity, and improve molding efficiency.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] With a simple structure, two forming cavities are set by setting two pairs of lower mold cores and upper mold cores. At the same time, the space of the lower mold plate and the second lower mold core is used to set the inclined guide post core-pulling slider assembly, which can form two products at the same time, resulting in high processing efficiency. The reasonable use of space to set a relatively large number of inclined guide post core-pulling slider assemblies facilitates the forming of the mounting holes and vent holes on the side of the compressor cylinder head, reducing subsequent processing steps.

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] like Figure 1-4 As shown, this utility model provides the following technical solution to solve the technical problem that it is difficult to set two corresponding oblique cores on the mold due to the location of the vent hole of the compressor cylinder head: A die-casting mold for a compressor cylinder head includes an upper mold plate 1 and a lower mold plate 2 arranged vertically. A first lower mold core 3 and a second lower mold core 4 are embedded side by side on the lower mold plate 2. A first upper mold core 6 and a second upper mold core 5, respectively matching the first lower mold core 3 and the second lower mold core 4, are embedded side by side on the upper mold plate 1. A forming cavity is formed between the first lower mold core 3 and the first upper mold core 6, and between the second lower mold core 4 and the second upper mold core 5. A forming slider 9 is provided on the upper side of the lower mold plate 2, on one side of the first lower mold core 3 and the second lower mold core 4. A driving cylinder 10 is installed on the rear side of the forming slider 9. The inner side of the molding slider 9 is equipped with a feed plate 18 located on the upper side of the molding slider 9. The feed plate 18 matches the feed channel 15 on the upper template 1. The rear ends of the molding slider 9 are equipped with first inclined guide post core-pulling slider assemblies 11. The lower template 2 on one side of the first lower mold core 3 is obliquely provided with a second inclined guide post core-pulling slider assembly 14. The lower template 2 on one side of the first lower mold core 3 and the second lower mold core 4 are respectively equipped with third inclined guide post core-pulling slider assemblies 13. The second lower mold core 4 is embedded with a fourth inclined guide post core-pulling slider assembly 12 that is parallel to the second inclined guide post core-pulling slider assembly 14. By setting two pairs of lower mold cores and upper mold cores, two molding cavities are set up. At the same time, the space of the lower template 2 and the second lower mold core 4 is used to set up the inclined guide post core-pulling slider assembly. Two products can be formed at the same time, resulting in high processing efficiency.

[0019] Specifically, after the upper mold plate 1 and the lower mold plate 2 are closed, the feeding channel 15 can feed the material, which enters the two forming cavities through the flow channel between the feeding plate 18 and the forming slider 9 for forming. After forming, the mold is opened. When the mold is opened, the first inclined guide pillar core-pulling slider assembly 11, the second inclined guide pillar core-pulling slider assembly 14, the third inclined guide pillar core-pulling slider assembly 13 and the fourth inclined guide pillar core-pulling slider assembly 12 act simultaneously, and the core is pulled out from the product, which makes it easier to eject the product and open the mold.

[0020] The size of the fourth inclined guide post core-pulling slider assembly 12 is smaller than that of the second inclined guide post core-pulling slider assembly 14. The fourth inclined guide post core-pulling slider assembly 12 can effectively utilize the space of the second lower mold core 4.

[0021] In this embodiment, as Figure 3-4 As shown, the first inclined guide post core-pulling slider assembly 11, the second inclined guide post core-pulling slider assembly 14, the third inclined guide post core-pulling slider assembly 13, and the fourth inclined guide post core-pulling slider assembly 12 all include a sliding seat 22 and a core-pulling slider 23 disposed within the sliding seat 22. An inclined guide post 21 is obliquely disposed within the core-pulling slider 23, and a forming core-pulling rod 24 inserted into the forming mold cavity is disposed at the end of the core-pulling slider 23. When the upper mold plate 1 and the lower mold plate 2 are separated, the sliding seat 22 will retract simultaneously, thereby realizing the synchronous core-pulling of the forming core-pulling rod 24.

[0022] In this embodiment, two branch flow channels 17 and a central flow channel 16 are formed between the feed plate 18 and the forming slider 9. The branch flow channels 17 extend into the two forming cavities respectively. The central flow channel 16 is connected to the two forming cavities through the branch flow channels 19 on both sides, which can realize the rapid feeding and forming of the two forming cavities simultaneously. Through the central flow channel 16 and the branch flow channels 17, molten aluminum can be simultaneously introduced into the two forming cavities from the front and the side, resulting in a fast forming speed.

[0023] In this embodiment, as Figure 1 As shown, a top plate 7 is installed below the lower template 2. Several ejector pins 8 are arranged on the top plate 7 and inserted vertically into the molding cavity, which can realize the ejection of products from the two molding cavities. The ejector pins 8 can be ejected together with the products formed in the molding cavity, as well as the runner and slag bag.

[0024] In this embodiment, as Figure 1-3 As shown, the upper side of the lower template 2 is provided with vacuum pump mounting slots 20 on the sides of the first lower mold core 3 and the second lower mold core 4 respectively. The vacuum pump mounting slots 20 are equipped with vacuum pumps that match the corresponding exhaust blocks 25. The vacuum pumps can be used to quickly evacuate the air in the molding cavity, reduce the air holes in the molded product in the molding cavity, and improve the molding efficiency.

[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0026] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
