Description

Technical Field

[0001] The present invention relates to an injection mold, in particular to an injection mold for a B-pillar upper trim plate and a side-sliding demoulding mechanism thereof. Background Art

[0002] The structure of the injection mold for the B-pillar upper trim to be injection molded is shown in the attached figure. Figure 1 As shown, its main structure includes a plate body e, and the two side surfaces of the plate body e are an upper plate surface a and a lower plate surface b respectively. A protrusion d is integrally formed on the joint edge c between the upper plate surface a and the lower plate surface b. The shape of the protrusion d is a T-shaped cone, and the small end of the protrusion d is connected to the joint edge c.

[0003] There are at least two difficulties in designing the injection mold for the B-pillar upper trim panel:

[0004] First, the large end of the protrusion d faces the outside of the plate body e, and the side core-pulling structure of the corresponding injection molding of the protrusion d is difficult to be demoulded from the plate body e;

[0005] Second, the ejector pin of the B-pillar upper trim injection mold is usually set on the side of the lower plate surface b. Even if the side core-pulling structure for injection molding the protrusion d is designed, the side core-pulling structure is likely to interfere with the action of the ejector pin.

[0006] Therefore, mold designers must overcome the above two design difficulties to complete the new B-pillar upper trim injection mold. Summary of the Invention

[0007] In view of this, the first object of the present invention is to provide a side-sliding demoulding mechanism, which can not only smoothly disengage from the protrusion, but also avoid interference with the corresponding ejector pin, and has a reasonable structural design.

[0008] In order to solve the above technical problems, the technical solution of the present invention is:

[0009] A side-sliding demoulding mechanism includes a ejector, a template, and a block driver. The template is provided with an injection molding area for molding a B-pillar upper trim panel. A main molding block is slidably connected to the template. The block driver is used to drive the main molding block to slide. The ejector includes an ejector rod that passes through the template. The end of the ejector rod is used to eject the B-pillar upper trim panel that has been injection-molded in the injection molding area.

[0010] The side sliding rod further comprises a side sliding block, wherein the side sliding block is slidably connected to the template, and the sliding direction of the side sliding block is consistent with the sliding direction of the main molding block. A long slot is formed through the side sliding block. The two ends of the side sliding rod are respectively a molding end and a sliding end. The molding end obliquely passes through the main molding block and extends to the injection molding area. The molding end is used for injection molding a protrusion of the B-pillar upper trim panel. The sliding end is slidably connected to the long slot.

[0011] When the main forming block slides a first distance toward the side of the side slider, the main forming block drives the side sliding rod to slide toward the template, and the forming end is separated from the protrusion of the injection-molded B-pillar upper trim panel;

[0012] When the main molding block continues to slide toward the side slider for a second distance, the main molding block pushes the side slider and the side sliding rod to slide toward the side away from the injection molding area.

[0013] Through the above technical solution, the B-pillar upper trim panel is first injection molded in the injection molding area; in the first step, the block driving component first drives the main molding block to move a first distance toward the side of the side slider, and the main molding block drives the side slide bar to slide toward the side of the template, and the molding end is separated from the protrusion of the injection-molded B-pillar upper trim panel; in the second step, the main molding block continues to slide toward the side of the side slider, and the main molding block pushes the side slider and the side slide bar to slide together toward the side away from the injection molding area, and the molding end is linearly moved away from the protrusion of the injection-molded B-pillar upper trim panel; at this time, the end of the ejector rod can smoothly eject the injection-molded B-pillar upper trim panel;

[0014] The above-mentioned molding and ejection process effectively overcomes the following technical difficulties: First, the molding end slides toward the side close to the template and then moves horizontally in a straight line to smoothly achieve demolding; second, the molding end can move horizontally in a straight line to avoid interference with the ejector rod.

[0015] Preferably, it further comprises a fixing member, wherein the fixing member comprises a fixing frame, and the fixing frame is connected to the side slider via bolts;

[0016] A frame sliding groove is provided in the fixed frame, a frame sliding block is slidably provided in the frame sliding groove, and a rotating shaft is connected between the sliding end and the frame sliding block.

[0017] Through the above technical solution, the frame slide groove in the fixed frame and the sliding end are connected through the frame slider, the frame slide groove and the rotating shaft. Not only will it not hinder the sliding action of the side sliding bar, but the sliding action of the sliding end of the side sliding bar will be more stable, thereby ultimately improving the sliding stability of the entire side sliding bar.

[0018] Preferably, a T-shaped slide groove is provided through the fixed frame, and two oppositely arranged grooves in the T-shaped slide groove are the frame slide grooves, and the frame slider is slidably connected in each of the frame slide grooves;

[0019] A blocking piece is provided on the outer frame wall of the fixed frame, and the blocking piece blocks the slot opening position of the T-shaped slot, and the blocking piece is used to block the frame sliding block in the T-shaped slot.

[0020] Through the above technical solution, firstly, since the T-shaped slide groove runs through the fixed frame, the frame slider can be smoothly installed into the fixed frame from the outside, and disassembly and assembly are convenient; secondly, the two relatively set frame slide grooves and the frame slider cooperate with each other, and the movement stability of the sliding end is higher.

[0021] Preferably, a hook body is installed on the main forming block, and the two ends of the hook body are respectively a hooking end and a connecting end, the connecting end is connected to the mounting block, the hooking end extends to the side of the side slider away from the main forming block, and the hooking end can be against the side wall of the side slider away from the main forming block.

[0022] Through the above technical solution, when the main molding block and the side slider need to be reset, the block driving component will drive the main molding block to move toward the injection molding area, and the hook body and the main molding block will move synchronously. The hooking end of the hook body will be against the side wall of the side slider away from the main molding block, and the side slider can be moved back to its original position to achieve automatic reset; by adopting the above hook body reset structure, there is no need to use an additional power source, and the side slider can achieve automatic sliding reset, with a high compact structure and accurate movement.

[0023] Preferably, the ejector rod is located at a position on one side of the forming end close to the template.

[0024] Through the above technical solution, since the forming end will eventually undergo linear translational motion, the ejector pin is located on the side of the forming end close to the template. Under the premise of ensuring that there is no mutual interference, the lateral design dimensions of the entire mold are effectively controlled and the structural compactness is fully enhanced.

[0025] Preferably, the distance between the forming end of the side sliding bar and the template is smaller than the distance between the sliding end of the side sliding bar and the template;

[0026] A first trigger rod and a second trigger rod are slidably connected in the side slider;

[0027] The two ends of the first trigger rod are respectively a first driving end and a first trigger end, and the first driving end is used to abut against the rod wall of the side sliding rod;

[0028] The two ends of the second trigger rod are respectively a second driving end and a second trigger end, the second trigger end protrudes from the outer side wall of the side slider, and the second driving end is used to cooperate with the first trigger end;

[0029] The hooking end of the hook body abuts against the second triggering end of the second triggering rod, the second driving end is used to cooperate with the first triggering end, the first driving end abuts against the rod wall of the side sliding rod, and the side sliding rod moves toward the template direction.

[0030] With the above technical solution, as the main forming block moves toward the injection molding area, the main forming block will exert an extrusion force on the side slide bar toward the template side, which will cause a high degree of wear and damage between the main forming block and the side slide bar.

[0031] By setting a first trigger rod and a second trigger rod, when the main molding block moves toward the injection molding area, the hooking end of the hook body abuts against the second triggering end of the second trigger rod, and the second driving end is used to cooperate with the first triggering end. The first driving end abuts against the wall of the side sliding rod, and the side sliding rod moves toward the template, thereby actively pushing the side sliding rod to the side of the template, thereby greatly reducing the friction damage caused by the main molding block and the side sliding rod.

[0032] Preferably, a through hole for the side sliding rod to pass through is provided in the main forming block, and the diameter of the through hole is larger than the diameter of the side sliding rod.

[0033] Through the above technical solution, the side sliding rod can move within the through hole to a certain extent, thereby further reducing the degree of friction damage generated by the main forming block and the side sliding rod.

[0034] Preferably, a reset member is further included, and the reset member includes a reset spring. The reset spring is connected between the first trigger rod and the side slider, and the reset spring is used to pull the first trigger rod away from the template and reset it.

[0035] Through the above technical solution, when the hook body is separated from the second trigger rod, the reset spring pulls the first trigger rod toward the side of the template, and the first trigger rod and the second trigger rod will return to their initial positions, achieving an automatic reset effect.

[0036] The second object of the present invention is to provide an injection mold for a B-pillar upper trim panel, wherein the demoulding mechanism in the injection mold can be smoothly demoulded from the B-pillar upper trim panel, and the overall injection mold has a highly compact structure.

[0037] In order to solve the above technical problems, the technical solution of the present invention is:

[0038] A B-pillar upper trim injection mold includes a movable mold, a fixed mold, and the above-mentioned side-sliding demolding mechanism. The block driving component includes a block driving rod, which is fixedly connected to the fixed mold. The block driving rod obliquely penetrates the main molding block and is used to drive the main molding block to slide. The movable mold includes the template.

[0039] With the above technical solution, after the movable mold and the fixed mold are closed together, the B-pillar upper trim panel can be injection molded in the injection molding area on the template; after the movable mold and the fixed mold are separated from each other, a block driving rod is fixed to the fixed mold, and the block driving rod and the movable mold will move relative to each other. The block driving rod can drive the main molding block to slide. At this time, the separation force of the movable mold and the fixed mold is reasonably utilized, and there is no need to set a drive source in the block driving component, which has a highly compact structure.

[0040] In addition, its internal side-sliding demoulding mechanism can smoothly demould with the B-pillar upper trim panel. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 2 As shown in the horizontal placement state, the sliding direction of the main forming block 6 is also the horizontal transverse direction.

[0054] See also Figure 4 as well as Figure 5 A side slider 8 is slidably connected to the template 3. The side slider 8 is located on the side of the main molding block 6 facing away from the injection molding area 5. The sliding direction of the side slider 8 is consistent with the sliding direction of the main molding block 6. A long groove 9 is formed through the side slider 8. In this embodiment, the long groove 9 is a waist-shaped groove.

[0055] See also Figure 3 、 Figure 4 as well as Figure 5 A side sliding bar 7 is also provided. It has a forming end 71 and a sliding end 72 at either end. The forming end 71 obliquely passes through the main forming block 6 and extends to the injection molding area 5. This forming end 71 is used to injection-mold the protrusion d of the B-pillar upper trim. The sliding end 72 is slidably connected to the elongated slot 9. The slot 9's length allows for sliding movement of the sliding end 72.

[0056] See also Figure 3 as well as Figure 4 , further comprising a fixing member 10. The fixing member 10 is mainly used to stabilize the sliding motion of the sliding end 72 of the side sliding bar 7.

[0057] Among them, see Figure 4 The fixing member 10 includes a fixing frame 101, and the fixing frame 101 is connected to the side slider 8 by bolts.

[0058] See also Figure 4 as well as Figure 5 The fixed frame 101 is provided with a T-shaped slot 102. Two oppositely disposed slots within the T-shaped slot 102 are the frame slots 103. A frame slider 104 is slidably connected within each of the frame slots 103. A frame slider 104 is slidably disposed within each of the frame slots 103. A rotating shaft 14 is connected between the sliding end 72 and the frame slider 104.

[0059] See also Figure 5 A blocking piece 105 is provided on the outer frame wall of the fixed frame 101 , and the blocking piece 105 blocks the slot opening position of the T-shaped slot 102 . The blocking piece 105 is used to block the frame slider 104 in the T-shaped slot 102 .

[0060] See also Figure 3 as well as Figure 4 A ejector 2 is also provided, comprising an ejector rod 21 that passes through the mold plate 3. The end of the ejector rod 21 is used to eject the B-pillar upper trim panel that has been injection molded in the injection molding area 5. The ejector rod 21 is located on the side of the molding end 71 that is close to the mold plate 3.

[0061] Also, see Figure 4 A hook body 11 is installed on the main forming block 6. The two ends of the hook body 11 are respectively a hook end 111 and a connecting end 112. The connecting end 112 is connected to the mounting block. The hook end 111 extends to the side of the side slider 8 away from the main forming block 6. The hook end 111 can be against the side wall of the side slider 8 away from the main forming block 6.

[0062] The actual demoulding movement steps of the above-mentioned side sliding demoulding mechanism are as follows:

[0063] Step 1: The B-pillar upper trim is injection molded in the injection molding area 5. The main molding block 6 slides a first distance toward the side slider 8. The main molding block 6 drives the side slider 7 to slide toward the template 3. The molding end 71 disengages from the protrusion d of the injection molded B-pillar upper trim.

[0064] Step 2: The main molding block 6 continues to slide a second distance toward the side slider 8. The main molding block 6 pushes the side slider 8 and the side sliding rod 7 to slide away from the injection molding area 5. At this time, the molding end 71 and the ejector rod 21 are offset from each other to avoid interference.

[0065] Step 3: The ejector rod 21 ejects the B-pillar upper trim panel located in the injection molding area;

[0066] Step 4: The main molding block 6 slides away from the side slider 8, and the hook end 111 of the hook body 11 can pull the side slider 8. The side slider 8 and the side sliding rod 7 move synchronously with the main molding block 6 toward the injection molding area 5 until the reset is completed.

[0067] The first distance mentioned above can be selected as 5mm-10mm, and the second distance will increase the distance of 5mm-10mm on the basis of the first distance. Example

[0068] The difference from Example 1 is that:

[0069] See also Figure 6 as well as Figure 7 The distance between the forming end 71 of the side sliding bar 7 and the template 3 is f, and the distance between the sliding end 72 of the side sliding bar 7 and the template 3 is g, where f is smaller than g. Figure 6 As shown, the entire side sliding bar 7 is arranged at an angle.

[0070] A first trigger rod 15 and a second trigger rod 16 are slidably connected in the side slider 8 .

[0071] The first trigger rod 15 has two ends respectively comprising a first driving end 151 and a first trigger end 152 . The first driving end 151 is configured to abut against a wall of the side sliding rod 7 .

[0072] The two ends of the second trigger rod 16 are respectively a second driving end 161 and a second trigger end 162 . The second trigger end 162 protrudes from the outer wall of the side slider 8 . The second driving end 161 is used to cooperate with the first trigger end 152 .

[0073] The hook end 111 of the hook body 11 abuts against the second trigger end 162 of the second trigger rod 16, and the second driving end 161 is used to cooperate with the first trigger end 152. The first driving end 151 abuts against the rod wall of the side sliding rod 7, and the side sliding rod 7 moves toward the template 3.

[0074] A through hole 17 for the side sliding rod 7 to pass through is provided in the main forming block 6 . The diameter of the through hole 17 is h, and the diameter of the side sliding rod 7 is i, wherein h is greater than i.

[0075] It also includes a reset member 18, which includes a reset spring 181. The reset spring 181 is connected between the first trigger rod 15 and the side slider 8. The reset spring 181 is used to pull the first trigger rod 15 away from the template 3 and reset it.

[0076] A ball 19 is provided on the first driving end 151 , and the ball 19 is used to abut against the outer rod wall of the side sliding rod 7 .

[0077] The second driving end 161 is provided with a second driving inclined surface 1611, and the first triggering hole 20 is penetrated by the first triggering end 152, and the hole wall of the first triggering hole 20 is provided with a first driving inclined surface 21; the second driving end 161 is inserted into the first triggering hole 20, and the first driving inclined surface 21 and the second driving inclined surface 1611 are wedge-fitted against each other.

[0078] In actual use:

[0079] (1) When the main molding block 6 moves toward the injection molding area 5, the hook end 111 of the hook body 11 abuts against the second trigger end 162 of the second trigger rod 16, and the second driving end 161 is inserted into the first trigger hole 20. The first driving inclined surface 21 cooperates with the second driving inclined surface 1611 to attach the main molding block 6 to the injection molding area 5. Figure 6 As a reference for orientation, the second trigger rod 16 moves horizontally to the right, the first trigger rod 15 moves downward, the first driving end 151 of the first trigger rod 15 moves downward, the ball 19 of the first driving end 151 presses downward against the side sliding rod 7, the side sliding rod 7 moves downward, and the upper rod wall of the side sliding rod 7 is separated to a certain extent from the upper hole wall of the through hole 17;

[0080] (2) When the main forming block 6 moves toward the side slider 8, the hook end 111 of the hook body 11 is disengaged from the second trigger end 162, and the reset spring 181 pulls the first trigger rod 15 upward, and the second trigger end 162 will protrude from the outside of the side slider 8 again, realizing automatic reset. Example

[0081] A B-pillar upper trim injection mold, see Figure 8 , including a movable mold 12, a fixed mold 13, and a side-sliding demoulding mechanism as in Example 1 or Example 2.

[0083] During the actual operation, the parting force between the movable mold 12 and the fixed mold 13 is equivalent to the power source provided to the block driving rod 41, and the block driving rod 41 can drive the main molding block 6 to move accordingly.

[0084] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
