[0028] The following is combined with Figure 1-5 This application is described in further detail.

[0029] like Figure 1 1 is a schematic structural diagram of an automobile oil filter component 1 , which is an oil filter seat end cover, and the oil filter seat end cover is circular.

[0030] The present application embodiment discloses a mold for producing automobile oil filter components. Figure 2 and Figure 3 The mold for producing automotive oil filter components includes an upper mold base 2, a lower mold base 3, a punch 31, a first side die 32, a second side die 33, and an upper die 21. The lower mold base 3 is fixed to ensure the stability of the entire mold. The upper mold base 2 is detachably connected to the lower mold base 3, the punch 31 is connected to the lower mold base 3, and the upper die 21 is connected to the upper mold base 2. The first side die 32 and the second side die 33 are both slidably mounted on the lower mold base 3. The inner wall of the first side die 32, the inner wall of the second side die 33, the inner wall of the upper die 21, and the outer wall of the punch 31 form a mold cavity 11 for injection molding the automotive oil filter component 1. A drive assembly 4 is provided on the lower mold base 3 for driving the first side die 32 and the second side die 33 to slide.

[0031] The mold for producing automobile oil filter components in the embodiment of the present application can, during the mold closing process, drive the first side die 32 and the second side die 33 to automatically move closer to each other through the driving component 4, and form a part of the mold cavity 11 together with the punch 31, so that the mold closing process is more convenient to operate; during the demolding process of the oil filter component 1, the first side die 32 and the second side die 33 can be driven to automatically move away from each other through the driving component 4 to separate the formed oil filter component 1. Compared with the method of manually moving the module outward for demolding in the related art, it saves more manpower and can improve the demolding efficiency.

[0032] Reference Figure 2 and Figure 3The outer contour of the mold used to produce automobile oil filter components is rectangular. The upper mold base 2 is arranged on the upper side of the lower mold base 3, and the upper mold base 2 can slide up and down relative to the lower mold base 3; in addition, four guide columns 34 are provided on the lower mold base 3, and the four guide columns 34 are respectively arranged at the four corners of the lower mold base 3; the upper mold base 2 has four guide grooves, and the guide grooves correspond to the guide columns 34 one by one. The guide columns 34 are inserted into the guide grooves and slide with the guide grooves, thereby realizing the smooth lifting and lowering of the upper mold base 2.

[0033] The punch 31 is cylindrical and its central axis is vertically arranged. The bottom of the punch 31 is fixed to the lower die base 3 by bolts; the upper die 21 is fixed to the lower side of the upper die base 2, and the upper die 21 rises and falls with the upper die base 2 so as to form a part of the mold cavity 11 with the punch 31; the first side die 32 and the second side die 33 are arranged on both sides of the punch 31 relative to each other, and are slidably connected to the lower die base 3 in a direction perpendicular to the axis of the punch 31. When the first side die 32 and the second side die 33 are relatively close, the two can fit each other. At this time, the first side die 32 and the second side die 33 and the punch 31 form another part of the mold cavity 11.

[0034] Reference Figure 4 and Figure 5 The driving assembly 4 is arranged at the lower side of the mold cavity 11. The driving assembly 4 includes a power member 41, a driving gear 42, a driven gear 43, a first rack 44 and a second rack 45; the driven gear 43 is sleeved on the punch 31 and rotates with the punch 31. The punch 31 has an annular groove 311 for mounting the driven gear 43. The annular groove 311 is arranged at the lower side of the mold cavity 11 (the position of the annular groove 311 can be referred to Figure 2 ); The first rack 44 and the second rack 45 are arranged on both sides of the driven gear 43 relatively, and both are engaged with the driven gear 43. The first rack 44 is fixed to the lower side of the first side die 32 by bolts, and the second rack 45 is fixed to the lower side of the second side die 33 by bolts. The lower die base 3 is provided with a mounting groove 35 for sliding installation of the first rack 44 and the second rack 45; thus, the rotation of the driven gear 43 can drive the first side die 32 and the second side die 33 to move simultaneously in opposite directions.

[0035] The pitch circle diameter of the driving gear 42 is smaller than the pitch circle diameter of the driven gear 43. The driving gear 42 is rotatably connected to the lower die base 3 through the power shaft 421 and is engaged with the driven gear 43. The power member 41 is provided on the lower side of the driving gear 42. The power member 41 is a motor and is fixed to the lower die base 3 by bolts (the position of the power member 41 can be referred to Figure 2 ), the power shaft 421 extends downward, and the output end of the power member 41 is connected to the power shaft 421; thus, the power member 41 can drive the driving gear 42 to rotate, and the driven gear 43 rotates synchronously therewith, thereby driving the first side die 32 and the second side die 33 to slide relative to each other.

[0036] Those skilled in the art will appreciate that the mold drive assembly 4 in the embodiment of the present application is also applicable to injection molds of other automotive oil filter components 1 except the oil filter seat end cover, so as to achieve demoulding of two modules at the same time.

[0037] Reference Figure 3 and Figure 5 In order to improve the sliding stability of the first side die 32 and the second side die 33, a first slide rail 36 and a second slide rail 37 are provided on the lower die base 3. The first slide rail 36 and the second slide rail 37 are fixed to the lower die base 3 by bolts. The first slide rail 36 and the lower die base 3 form a first slide groove, and the first side die 32 slides in the first slide groove; similarly, the second slide rail 37 and the lower die base 3 form a second slide groove, and the second side die 33 slides in the second slide groove; thereby, the sliding direction of the first side die 32 and the second side die 33 can be limited, so that the first side die 32 and the second side die 33 slide smoothly.

[0038] Reference Figure 4 The first side die 32 is provided with two plug-in blocks 321 on the side facing the second side die 33. The two plug-in blocks 321 are respectively arranged on both sides of the first side die 32, and the plug-in blocks 321 are fixedly connected to the first side die 32 by bolts; the second side die 33 is provided with two plug-in grooves 331 on the side facing the first side die 32, and the plug-in grooves 331 correspond one-to-one to the plug-in blocks 321; when the first side die 32 and the second side die 33 are relatively fitted together, the two plug-in blocks 321 are respectively inserted into the two plug-in grooves 331, which can realize the fixation of the relative positions of the first side die 32 and the second side die 33, so as to improve the stability of the entire mold during the injection molding process.

[0039] Reference Figure 2 In order to improve the production efficiency of the automobile oil filter component 1, a cooling pipe 5 is provided in the punch 31. The cooling pipe 5 is used to pass a cooling medium (such as water). The cooling pipe 5 has an inlet end and an outlet end (not shown in the figure). The inlet end and the outlet end both pass through the punch 31 and the lower die base 3 in sequence and extend to the outside of the lower die base 3, so that the cooling medium can enter and exit the cooling pipe 5 and circulate in the cooling pipe 5.

[0040] The cooling pipe 5 is spirally arranged along the central axis of the punch 31, so that the cooling pipe 5 can be evenly close to the outer wall of the punch 31; thus, after the injection molding is completed, the cooling medium is injected into the cooling pipe 5. The cooling medium circulates in the cooling pipe 5 to take away the heat generated by the injection molding, thereby accelerating the cooling rate of the molten liquid in the mold cavity 11, thereby improving the production efficiency of the automotive oil filter component 1.

[0041] The implementation principle of the mold for producing automobile oil filter components in the embodiment of the present application is as follows: during the demolding process of the automobile oil filter component 1, the upper mold base 2 is first controlled to move upward, and the upper die 21 is then separated from the oil filter component 1, thereby realizing the demolding of the upper die 21; then, the power part 41 drives the driving gear 42 to rotate, and the driving gear 42 drives the driven gear 43 to rotate, thereby driving the first side die 32 and the second side die 33 to automatically move away from each other, thereby realizing the demolding of the first side die 32 and the second side die 33, and then the oil filter component 1 can be taken out upward; the above demolding process does not require manual operation, is more labor-saving, and can also improve the demolding efficiency.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
