DETAILED DESCRIPTION

[0024] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0026] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0027] One of the preferred embodiments of the present application is as follows: Figures 1 to 9 As shown, an injection mold for an automobile grille includes an upper mold, a lower mold, a first molding component 4, a second molding component 5 and a driving device 1, and the upper mold, the lower mold, the first molding component 4 and the second molding component 5 cooperate with each other to form a cavity for molding the desired product A (automobile grille); wherein the first molding component 4 is used to mold the mounting hole B of the product A, and the second molding component 5 is used to mold the mounting groove C (located on the side of the mounting hole B) of the product A, the first molding component 4 is slidably installed on the lower mold, and the second molding component 5 is slidably installed on the first molding component 4, and the driving device 1 is installed on the lower mold and cooperates with the second molding component 5 through the guide structure 3.

[0028] During demolding, the driving device 1 can drive the first molding component 4 and the second molding component 5 to perform a first process and a second process through the guide structure 3; in the first process, the second molding component 5 can slide in a first direction under the action of the guide structure 3, and the first molding component 4 remains stationary; in the second process, the second molding component 5 can drive the first molding component 4 to slide in a second direction under the action of the guide structure 3, and the first direction and the second direction do not overlap.

[0029] It can be understood that when demolding, the second molding component 5 is first moved and separated from the mounting groove C of the product A, so as to prepare for the subsequent separation of the first molding component 4; because if the second molding component 5 is not separated, because the mounting groove C is located on the side of the mounting hole B, then at this time it is equivalent to the first molding component 4 being stuck in the mounting hole B, thereby interfering with the separation of the first molding component 4.

[0030] It should be known that, by providing a guide structure 3, when the driving device 1 acts on the two molding components through the guide structure 3, the operation of the two molding components has a sequence, that is, first the second molding component 5 is separated from the mounting groove B under the action of the guide structure 3, and after the second molding component 5 and the mounting groove B are separated, the second molding component 5 can be driven by the guide structure 3 to drive the first molding component 4 to slide in the second direction together, that is, the mounting groove C and the mounting hole B of the automobile grid are demolded by a step-by-step demolding method, without the need for an additional driving source, and the structure is simple, thereby improving production efficiency and reducing production costs.

[0031] It should be noted that, for the first direction and the second direction in this application, Figure 2 As shown, the second direction is the direction downward away from the mounting hole B. Since the product itself is a curved structure, the second direction may be vertically downward or inclined downward; and since the mounting groove C is located on the inner side of the mounting hole B, the first direction is the direction perpendicular to the side of the mounting hole B, that is, the second direction and the first direction are perpendicular to each other.

[0032] One of the embodiments of the present application is as follows: Figures 3 to 6 As shown, the guide structure 3 includes a guide member 7, a first guide assembly 301 and a second guide assembly 302. The guide member 7 is slidably installed in the first molding assembly 4. The lower end of the guide member 7 is connected to the output end of the driving device 1 through the second guide assembly 302, and the upper end of the guide member 7 is connected to the second molding assembly 5 through the first guide assembly 301.

[0033] It should be noted that the specific structure and working principle of the drive device 1 are well-known technologies to those skilled in the art, so they will not be elaborated in detail here; common ones include hydraulic cylinders, pneumatic cylinders and linear motors, etc., and those skilled in the art can choose according to actual needs.

[0034] It is understandable that the initial state is Figure 4 As shown in (a), the two molding components are respectively located in the mounting hole B and the mounting groove C; when demoulding, that is, in the first process, the driving device 1 will drive the guide member 7 to move downward through the second guide component 302, such as Figure 4 As shown in (b) of FIG. 1 , the downwardly moved guide member 7 acts on the second molding assembly 5 through the first guide assembly 301, so that the second molding assembly 5 can slide in the first direction and away from the installation groove C (such as Figure 5In the second process, since the guide member 7 moves down to the limit position, when the guide member 7 continues to move down through the second guide assembly 302, the guide member 7 will drive the first molding assembly 4 to move down synchronously, thereby causing the first molding assembly 4 to slide in the second direction and away from the mounting hole B, thereby realizing the demoulding process.

[0035] As a further description of the above embodiment: Figure 8 As shown, a traction block 6 is installed at the output end of the driving device 1, and the second guide assembly 302 includes a second inclined guide bar 3022 and a second inclined guide groove 3021. The second inclined guide bar 3022 is installed with the traction block 6, and the second inclined guide groove 3021 is arranged at the lower end of the guide member 7. The second inclined guide bar 3022 and the second inclined guide groove 3021 form a sliding fit.

[0036] like Figure 8 As shown, the first guide assembly 301 includes an inclined guide groove 3011 and an inclined guide bar 3012. The inclined guide groove 3011 is arranged at the upper end of the guide member 7, and the inclined guide bar 3012 is installed on the second molding assembly 5. The inclined guide bar 3012 and the inclined guide groove 3011 form a sliding fit.

[0037] It is understandable that if Figure 6 as well as Fig. 9 As shown, when the driving device 1 shortens and drives the traction block 6 to move, the guide member 7 moves downward under the inclined sliding cooperation between the second inclined guide bar 3022 and the second inclined guide groove 3021. Figure 8 As shown, the downwardly moving guide member 7 cooperates with the inclined sliding cooperation of the inclined guide bar 3012 and the inclined guide groove 3011, so that the second molding component 5 can be separated from the installation groove C; when the guide member 7 continues to move downward, the guide member 7 will drive the first molding component 4 downward to separate from the installation hole B.

[0038] Of course, since the first molding assembly 4 is slidably installed in the lower mold, the first molding assembly 4 should be initially located at the highest position where it can move, such as Figure 6 As shown, the inclined guide bar 2 3022 and the inclined guide groove 2 3021 are at the highest position of cooperation, and the guide member 7 is also at this time to limit and lock the first molding component 4, that is, the guide member 7 is also at the highest position where it can move; but when the guide member 7 moves downward under the action of the inclined sliding cooperation between the inclined guide bar 2 3022 and the inclined guide groove 2 3021, that is, at this time, although the first molding component 4 can still be limited in the mounting hole B, the first molding component 4 relies on the cooperation between the second molding component 5 and the mounting groove C to keep the first molding component 4 stationary, which will affect the service life of the second molding component 5.

[0039] Therefore, in order to solve the above technical problems, in one embodiment of the present application, Figure 6 As shown, the top of the traction block 6 has an inclined section 601 and a horizontal section 602. When performing the first process, the horizontal section 602 can support and cooperate with the first molding component 4 to keep the first molding component 4 still, so that the second molding component 5 will not be subjected to force, thereby increasing the service life; and when performing the second process, the inclined section 601 cooperates with the first molding component 4 to make the first molding component 4 and the second molding component 5 slide synchronously along the second direction.

[0040] In this embodiment, Fig. 9 As shown, a limiting structure 8 is arranged between the traction block 6 and the lower die. Specifically, the limiting structure 8 includes a limiting rod and a limiting sleeve. The limiting rod is installed on the traction block 6, and the limiting sleeve is installed in the lower die. The limiting rod is slidably inserted in the limiting sleeve, so that the traction block 6 can slide in the lower die in a direction through the limiting structure 8, that is, the traction block 6 is limited, thereby improving stability.

[0041] like Figure 6 As shown, the first molding assembly 4 includes a first core block 401, and the first core block 401 is used to mold the mounting hole B of the product; when demolding, the first core block 401 slides in the second direction driven by the guide structure 3. Figure 8 As shown, the second molding assembly 5 includes a second core block 501, and the second core block 501 is used to mold the mounting groove C of the product; when demolding, the second core block 501 slides in the first direction driven by the guide structure 3. For this application, since there are two mounting grooves C corresponding to one mounting hole B, the second core block 501 is preferably a pair, and of course the corresponding first guide assembly 301 is also a pair.

[0042] The working principle of the utility model is:

[0043] When demoulding the mounting hole B and the mounting groove C of the car grille, Figure 6 As shown, the drive device 1 shortens and drives the traction block 6 to move rightward; Fig. 9 As shown, under the inclined sliding cooperation between the second inclined guide bar 3022 and the second inclined guide groove 3021, the guide member 7 will move downward; Figure 8 As shown in FIG. 1 , the downwardly moved guide member 7 is in the inclined sliding cooperation with the inclined guide bar 1 3012 and the inclined guide groove 1 3011, and the two second core blocks 501 will approach each other, as shown in FIG. Figure 5As shown, the second core block 501 is separated from the mounting groove C and demolded, and at this time the first core block 401 cooperates with the horizontal section 602 of the traction block 6, so that the first core block 401 remains stationary; when the traction block 6 continues to move right, the first core block 401 will cooperate with the inclined section 601, and of course the guide member 7 will continue to move downward under the inclined sliding cooperation of the inclined guide bar 3012 and the inclined guide groove 3011, and the downwardly moved guide member 7 will pull the first core block 401 and the second core block 501 to move downward synchronously, so that the first core block 401 is separated from the mounting hole B, and then the demolding is completed.

[0044] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments. The above embodiments and the description only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application. These changes and improvements fall within the scope of the present application for which protection is sought.
