Description

Technical Field

[0001] The utility model relates to the technical field of sensor processing, in particular to a sensor mould. Background Art

[0002] Injection molding is a common method for producing injection molded products. Specifically, it refers to injecting the heated and melted material into the mold cavity by high pressure, and then cooling and solidifying to obtain the injection molded product. The injection molding of the existing sensor mold requires employees to first remove the pin slider from the mold, then install the pin assembly into the pin slider, and then put them into the mold cavity together. When the injection mold is closed and opened, the upper mold inclined guide column of the upper mold drives the lower mold slider and the pin slider to move.

[0003] This method requires the pin slider to be removed from the mold and then the pin assembly to be installed. This not only takes a long time to operate, but also increases the workload of the employees. On the other hand, when the employees put the pin slider back into the mold cavity, there is a problem of damaging the mold parting surface, which seriously affects the life of the mold. Another problem is that after the upper mold inclined guide pin and its matching lower mold clamping structure are worn, they need to be replaced as a whole, which takes a long time and is expensive to repair. Utility Model Content

[0004] The utility model aims to solve the problem of low efficiency and high work intensity in removing a pin slide block from a mold to install a pin assembly. The utility model provides a sensor mold, which can improve efficiency and reduce work intensity.

[0005] In order to solve the above technical problems, the embodiment of the utility model discloses a sensor mold, comprising:

[0006] An upper die, comprising an upper die locking block, wherein the upper die locking block extends in a height direction and is movable in the height direction;

[0007] A lower mold, comprising a bottom plate, a mold cavity, a lower mold slider and a pin slider, wherein the mold cavity is located on one side of the bottom plate in a first direction, the lower mold slider is arranged on the bottom plate, the pin slider is used to install the pin assembly, and the lower mold slider is connected to the pin slider;

[0008] The upper mold locking block can move upward along the height direction to drive the lower mold slide block to move along the first direction and away from the mold cavity, so that the sensor mold is in an open mold state; or,

[0009] The lower mold slide block can move along the first direction and toward the mold cavity, so that the sensor mold is in a mold closing state;

[0010] A limiting groove is provided at one end of the lower mold slide along the first direction and facing the mold cavity, a limiting member is provided on the groove wall of the limiting groove along the first direction and facing the mold cavity, and a part of the pin slide is located in the limiting groove; in the mold opening state and the mold closing state, the limiting member can elastically abut against the pin slide along the first direction;

[0011] A pressing member is connected to the base plate in a manner that it can move along the height direction. In the mold opening state, the pressing member is located below the pin slider, and the pressing member can drive the pin slider to move upward in the limiting groove along the height direction.

[0012] With the above technical solution, during mold closing (i.e., the process of switching from mold opening state to mold closing state before injection molding), the lower mold slider and the pin slider are first manually pushed to the mold cavity along the first direction. At this time, the mold cavity is adjacent to the lower mold slider, and a part of the pin slider is located directly above the mold cavity. Then, the pin assembly is installed on the other part of the pin slider. After the installation is completed, the pin slider is pressed down in the height direction so that the pin assembly is completely placed in the mold cavity, and a part of the pin slider is also completely embedded in the limit groove. At this time, the upper mold locking block moves downward in the height direction until the downward movement is completed. At this time, the mold closing is completed and the injection molding of the product begins.

[0013] When the mold is opened (i.e., the process of changing from the mold closing state to the mold opening state after injection molding), the upper mold locking block moves upward in the height direction, and drives the lower mold slider to move in the first direction and away from the mold cavity. The lower mold slider drives the pin slider to move, that is, the lower mold slider and the pin slider are away from the mold cavity, and the pin slider completes the core pulling, that is, the pin slider is separated from the pin assembly installed before injection molding. At this time, the pin slider is located directly above the top pressure piece, and the top pressure piece moves up in the height direction to lift the pin slider so that it is higher than the surface of the mold cavity and the lower mold slider, and then the top pressure piece is reset. At this time, the pin slider is not supported by the top pressure piece, and the limit piece in the limit groove elastically abuts against the pin slider in the first direction to limit the pin slider from moving downward in the height direction, thereby maintaining the pin slider higher than the mold cavity and the lower mold slider, so as to facilitate the next installation of the pin assembly.

[0014] In summary, the installation of the pin assembly of the present application does not require the removal of the pin slider, which reduces the labor intensity of the workers on the one hand, and avoids the collision between the pin slider and the parting surface of the mold cavity during the placement of the pin slider on the other hand, thereby reducing the wear of the mold during the injection molding process and increasing the service life of the mold. In addition, the present application eliminates the existing upper mold inclined guide column structure, thereby reducing the cost of mold maintenance and replacement.

[0015] According to another specific embodiment of the utility model, both ends of the upper mold locking block in the second direction are provided with a first guide portion, the first guide portion extends along the third direction, and along the first direction, the upper end of the first guide portion is closer to the mold cavity than the lower end thereof; the lower mold slide block is provided with a slide groove at one end along the first direction and away from the mold cavity, and the upper mold locking block can move up and down along the height direction in the slide groove; guide members are protrudingly provided on the two groove walls of the slide groove along the second direction, the guide members can be connected to the first guide portion, and the guide members can slide on the first guide portion along the third direction; the first direction is perpendicular to the second direction, and the third direction is inclined to the first direction and the second direction.

[0016] With the above technical solution, when the upper die locking block moves downward in the height direction, the first guide portion will first contact the guide member, and the first guide portion will squeeze the guide member in the second direction, so that the end of the guide member is flush with the groove wall of the slide groove in the second direction, thereby facilitating the upper die locking block to be inserted into the slide groove. When the upper die locking block moves downward to a suitable position, the force of the first guide portion squeezing the guide member in the second direction is removed, and the guide member can pop out to be partially exposed in the slide groove and connected to the first guide portion, so that the upper die locking block moves upward to drive the lower die slider to move in the first direction and away from the mold cavity.

[0017] According to another specific embodiment of the present invention, the first guide portion includes a first guide plane, which is facing away from the mold cavity along the first direction; the guide member includes a second guide plane, which is facing the first guide plane along a fourth direction and is closely connected thereto, and the fourth direction is perpendicular to the third direction.

[0018] By adopting the above technical solution, the first guide plane and the second guide plane are both rectangular in shape, and the surface-to-surface fitting connection between the two can better ensure the stability of the connection, so that the upward movement of the upper mold locking block drives the lower mold slider to move along the first direction and away from the mold cavity, and then the lower mold slider drives the pin slider to move, so as to realize the pin slider being separated from the pin assembly.

[0019] According to another specific embodiment of the present utility model, the first guide portion also includes a first abutment surface, which is perpendicular to the first guide plane; the end of the guide member extending into the slide groove along the second direction can be elastically connected to the first abutment surface of the first guide portion.

[0020] According to another specific embodiment of the utility model, the limiting groove includes two clamping grooves arranged opposite to each other along the second direction, and the pin slider includes two convex portions arranged opposite to each other along the second direction, and the two convex portions are clamped in the two clamping grooves.

[0021] By adopting the above technical solution, the protrusion of the pin slider is clamped in the slot, thereby fixing the pin slider relative to the lower mold slider in the first direction and the second direction, so that the lower mold slider can drive the pin slider to move along the first direction and away from the mold cavity.

[0022] According to another specific embodiment of the present utility model, a spherical groove is provided on the surface of the pin slider facing away from the mold cavity, and a part of the limiting member can be inserted into the spherical groove along the first direction.

[0023] By adopting the above technical solution, part of the limiting member is inserted into the spherical groove to limit the movement of the pin slider in the height direction.

[0024] According to another specific embodiment of the utility model, the spherical groove includes a first spherical groove and a second spherical groove arranged at intervals along the height direction, and the first spherical groove and the second spherical groove each include two arranged at intervals along the second direction; the limiting member includes two arranged at intervals along the second direction, and the two limiting members are elastically abutted against the two first spherical grooves or the two second spherical grooves.

[0025] By adopting the above technical solution, when the mold is closed, the pin slider is not lifted up by the pressing piece, and the first limit piece and the second limit piece are elastically abutted against the two second spherical grooves. When the pressing piece lifts the pin slider and moves the pin slider to the highest position in the height direction, the first limit piece and the second limit piece are abutted against the two first spherical grooves, and then the pressing piece is reset. The pin slider relies on its clamping connection with the limit groove and the action of the first limit piece and the second limit piece, and it can still maintain a state higher than the upper surface of the lower mold slider.

[0026] According to another specific embodiment of the utility model, the groove wall of the slide groove along the first direction is a first locking surface, and the upper mold locking block is provided with a second locking surface at one end along the first direction, and the first locking surface and the second locking surface both extend along the third direction and are fitted and connected along the first direction.

[0027] By adopting the above technical solution, the first locking surface and the second locking surface are fitted together along the first direction, so that the upper mold locking block presses the lower mold slider in the first direction, limiting the movement of the lower mold slider in the first direction.

[0028] According to another specific embodiment of the present utility model, two groove walls of the sliding groove along the second direction are respectively provided with mounting holes extending along the second direction, and the mounting holes are used to install the guide member.

[0029] By adopting the above technical solution, a part of the guide member is located in the mounting hole, and the other part extends out of the mounting hole along the second direction, thereby abutting against the first guide portion, thereby realizing the upward movement of the upper mold locking block to drive the lower mold slider to move in the first direction and away from the mold cavity.

[0030] According to another specific embodiment of the present utility model, the guide member includes a first limiting surface, the mounting hole includes a second limiting surface, and the first limiting surface and the second limiting surface abut against each other along the second direction.

[0031] By adopting the above technical solution, the second limiting surface faces the first limiting surface along the second direction and abuts against it, thereby forming a limit for the guide member in the second direction and toward the slide groove, preventing the guide member from sliding out of the mounting hole along the second direction and toward the slide groove.

[0032] According to another specific embodiment of the utility model, the mounting hole includes a first hole and a second hole that are connected, the aperture of the first hole is smaller than the aperture of the second hole, so as to form the second limiting surface at the connection between the first hole and the second hole; the guide member includes a first cylindrical member and a second cylindrical member that are connected, the radial dimension of the first cylindrical member is smaller than the radial dimension of the second cylindrical member, so as to form the first limiting surface at the connection between the first cylindrical member and the second cylindrical member; the first hole is used to accommodate the first cylindrical member, and the second hole is used to accommodate the second cylindrical member.

[0033] According to another specific embodiment of the present invention, a blocking member is provided at the opening of the second hole along the second direction and away from the first hole to limit the guide member from sliding out of the opening of the second hole along the second direction.

[0034] By adopting the above technical solution, the blocking member blocks the guiding member to prevent the guiding member from sliding out of the second hole along the second direction, causing the upper die locking block to be unable to drive the lower die slide block to move.

[0052] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0053] refer to Figures 1 to 4 The present application provides a sensor mold 1, comprising: an upper mold 2, a lower mold 3 and a top pressing member 4, wherein the upper mold 2 comprises an upper mold locking block 20, and the upper mold locking block 20 is arranged along the height direction ( Figure 2 The upper die 2 and the upper die locking block 20 extend in the height direction (shown in the Z direction) and can move in the height direction. For example, the height direction movement of the upper die 2 and the upper die locking block 20 is manually operated by a staff member, or mechanical equipment can be used to lift and put down.

[0054] Exemplarily, the upper surface of the upper mold locking block 20 includes a first surface 200 and a second surface 201, and the first surface 200 and the second surface 201 are connected along a first direction ( Figure 2 W direction) but along the height direction ( Figure 2 Specifically, the height of the first surface 200 is higher than the height of the second surface 201. That is, the upper surface of the upper mold locking block 20 is stepped.

[0055] Optionally, both the first surface 200 and the second surface 201 are provided with a plug hole 202 extending in the height direction, and a columnar member 203 can be inserted and fixed in the plug hole 202, and the columnar member 203 is arranged in the height direction ( Figure 1The upper mold locking block 20 is protruded from the first surface 200 and the second surface 201 (shown in the Z direction). This arrangement facilitates the staff to move or perform other operations on the upper mold locking block 20 through the columnar member 203.

[0056] The lower mold 3 includes a bottom plate 11, a mold cavity 30, a lower mold slider 31 and a pin slider 32. The mold cavity 30 is located in the first direction ( Figure 2 The lower mold slider 31 is arranged on the bottom plate 11, and the pin slider 32 is used to install the pin assembly. The lower mold slider 31 and the pin slider 32 are connected. Exemplarily, the pin slider 32 includes a first part 320 and a second part 321. The first part 320 is located on the bottom plate 11, and the second part 321 is used to install the pin assembly. The second part 321 extends along the first direction and can place the pin assembly in the mold cavity 30 to perform the injection molding of the product.

[0057] Exemplarily, the mold cavity 30 is a space for molding a product (eg, a WSS wheel speed sensor).

[0058] For example, the first direction ( Figure 1 W direction) including the mold closing direction ( Figure 1 U direction) and mold opening direction ( Figure 1 The mold closing direction is the direction of the lower mold slider 31 toward the mold cavity 30, and the mold opening direction is the direction of the lower mold slider 31 away from the mold cavity 30.

[0059] It should be noted that the pin assembly, as a part of the product (such as the WSS wheel speed sensor), needs to be installed on the pin slider 32 and placed in the mold cavity 30 before injection molding. After the injection molding is completed, the pin assembly needs to be retained in the injection-molded product, and at this time, the pin slider 32 needs to be moved along the mold opening direction ( Figure 1 Move the assembly (in the direction of V) to disengage from the pin assembly.

[0060] The upper die locking block 20 can be adjusted along the height direction ( Figure 1 The lower mold slide 31 moves upward in the mold opening direction ( Figure 1 The sensor mold 1 is moved in the mold opening direction (as shown in the V direction) to put the sensor mold 1 in the mold opening state. Further, the movement of the lower mold slider 31 in the mold opening direction drives the pin slider 32 connected thereto to move in the mold opening direction, so that the pin slider 32 is away from the mold cavity 30, so as to realize the separation of the pin slider 32 and the pin assembly.

[0061] The lower mold slide 31 can move along the mold closing direction ( Figure 1The sensor mold 1 is moved in the mold closing state. Further, the lower mold slider 31 moves in the mold closing direction, driving the pin slider 32 connected thereto to move in the mold closing direction, so that the pin slider 32 is close to the mold cavity 30, and the second part 321 of the pin slider 32 and the pin assembly are placed in the mold cavity 30 to perform the product injection molding.

[0062] refer to Figure 1 and Figure 5 Optionally, the mold 1 further includes a fixing seat 8, wherein the two fixing seats 8 are respectively located in the second direction ( Figure 5 The two ends of the upper mold slider 31 in the second direction are both convexly provided with a sliding portion 3111, and the bottom surface 80 of the fixed seat 8 and the upper surface 314 of the sliding portion 3111 are arranged along the height direction ( Figure 5 The inner surface 81 of the fixed seat 8 and the side surface 315 of the upper mold slider 31 are fitted along the second direction, thereby realizing the movement of the upper mold slider 31 relative to the fixed seat 8 along the first direction.

[0063] refer to Figure 6 and Figure 7 , the lower die slider 31 moves along the first direction ( Figure 6 A limiting groove 310 is provided at one end (shown in the W direction) and facing the mold cavity 30. A limiting member 320 is provided on the groove wall of the limiting groove 310 along the first direction and facing the mold cavity 30. The first part 320 of the pin slider 32 is located in the limiting groove 310. In both the mold opening state and the mold closing state, the limiting member 320 can elastically abut against the pin slider 32 along the first direction. For example, the elastic abutment between the limiting member 320 and the pin slider 32 can, on the one hand, control the pin slider 32 in the height direction ( Figure 6 On the one hand, it is also convenient for the pressing member 4 described later to lift the pin slider 32 without causing resistance to the upward movement of the pin slider 32.

[0064] Optionally, the limiting groove 310 is T-shaped.

[0065] Exemplarily, the lower die slider 31 is moved in the first direction ( Figure 6 W direction) and one end facing the mold cavity 30 is provided with two limiting grooves 310, and the two limiting grooves 310 are arranged along the second direction ( Figure 6 The two limiting grooves 310 are arranged at intervals, and the two limiting grooves 310 respectively accommodate the pin sliders 32. That is, the upward movement of an upper mold locking block 20 can drive a lower mold slider 31 to move along the mold opening direction ( Figure 7 The lower mold slider 31 can also drive the movement of two pin sliders 32 at the same time. In other words, the mold opening action of two injection molded products can be realized in one mold 1 through one lower mold slider 31.

[0066] The above-mentioned top pressing member 4 is arranged in the height direction ( Figure 6 The top pressure piece 4 is movably connected to the bottom plate 11 (as shown in the Z direction). In the mold opening state, the top pressure piece 4 is located below the pin slider 32, and the top pressure piece 4 can drive the pin slider 32 to move upward in the limit groove 310 along the height direction.

[0067] Exemplarily, the pressing member 4 is connected to a motor (not shown in the figure) to provide power for the pressing member 4 .

[0068] For example, in the mold closing state (such as Figure 6 As shown), the top pressing member 4 and the pin slider 32 are arranged along the first direction ( Figure 6 When the upper die locking block 20 moves upward in the height direction, the lower die slide 31 moves in the mold opening direction ( Figure 6 At the same time, the pin slider 32 located in the limiting groove 310 slides along with it until the sliding ends, and the sensor mold is in an open mold state. At this time, the pressing piece 4 is located below the pin slider 32, and then the pressing piece 4 lifts the pin slider 32 in the height direction to make the pin slider 32 higher than the surface of the mold cavity 30, thereby facilitating the staff to install the pin assembly.

[0069] It should be noted that the downward movement of the pin slider 32 in the limiting groove 310 is achieved by manual pressing, that is, the staff presses the lifted pin slider 32 downward in the height direction so that the first part 320 is located in the limiting groove 310 and the second part 321 is placed in the mold cavity 30 to complete the preparation work before injection molding.

[0070] Using the above technical solution, refer to Figure 1 , Figure 6 and Figure 7 When closing the mold (i.e., the process of switching from the mold opening state to the mold closing state before injection molding), the lower mold slider 31 and the pin slider 32 are manually moved along the mold closing direction ( Figure 1 The mold cavity 30 is now adjacent to the lower mold slider 31, and the second portion 321 of the pin slider 32 is located directly above the mold cavity 30. Then, the pin assembly is installed on the second portion 321 of the pin slider 32. After the installation is completed, the pin slider 32 is moved along the height direction ( Figure 1 The upper mold locking block 20 is then moved downward along the height direction until the downward movement is completed. At this time, the mold is closed and the product injection molding begins.

[0071] When the mold is opened (i.e., after injection molding, the process of switching from the mold closing state to the mold opening state), the upper mold locking block 20 is moved along the height direction ( Figure 1 The lower die slide 31 is driven to move upward along the mold opening direction ( Figure 1 The lower mold slider 31 drives the pin slider 32 to move along the mold opening direction, that is, the lower mold slider 31 and the pin slider 32 are away from the mold cavity 30, and the pin slider 32 completes the core pulling, that is, the pin slider 32 is separated from the pin assembly installed before injection molding. At this time, the pin slider 32 is located directly above the top pressing member 4, and the top pressing member 4 moves up in the height direction to lift the pin slider 32 so that it is higher than the surface of the mold cavity 30 and the lower mold slider 31, and then the top pressing member 4 is reset. At this time, the pin slider 32 is not supported by the top pressing member 4, and the limiting member 320 in the limiting groove 310 elastically abuts against the pin slider 32 along the first direction to limit the pin slider 32 from moving downward in the height direction, thereby maintaining the pin slider 32 above the mold cavity 30 and the lower mold slider 31, so as to facilitate the next installation of the pin assembly.

[0072] In summary, the installation of the pin assembly of the present application does not require the removal of the pin slider 32, which reduces the labor intensity of the workers on the one hand, and avoids the collision between the pin slider 32 and the parting surface of the mold cavity 30 during the placement of the pin slider 32 on the other hand, thereby reducing the wear of the mold during the injection molding process and increasing the service life of the mold. In addition, the present application eliminates the existing upper mold inclined guide column structure, thereby reducing the cost of mold maintenance and replacement.

[0073] refer to Figures 1 to 4 as well as Figure 6 and Figure 7 In some possible implementations, the second direction ( Figure 2 Both ends of the first guide portion 21 are provided with a first guide portion 21, and the first guide portion 21 is arranged along the third direction ( Figure 2 Along the first direction, the upper end 210 of the first guide portion 21 is closer to the mold cavity 30 than the lower end 211 thereof. Figure 1 The third direction is perpendicular to the first direction and the second direction, and the third direction is inclined to the first direction and the second direction.

[0074] That is, the first guide portion 21 includes two guide portions located at both ends of the upper mold locking block 20 in the first direction. Figure 1 The first guide portion 21 is in a downslope shape.

[0075] Exemplarily, the first guide portion 21 is located in the second direction ( Figure 2 The two side end surfaces of the upper mold locking block 20 are shown in the X direction, and the two first guide portions 21 protrude from the side end surface of the upper mold locking block 20 along the second direction.

[0076] The lower mold slide 31 is moved along the first direction ( Figure 7The upper mold locking block 20 can be moved in the slide groove 300 along the height direction ( Figure 7 The slide 300 moves up and down along the second direction ( Figure 7 A guide member 33 is protruded on the two groove walls (307, 308) of the embodiment of the present invention. The guide member 33 can be connected to the first guide portion 21, and the guide member 33 can be on the first guide portion 21 along the third direction ( Figure 6 For example, during the process of the upper mold locking block 2 moving up in the height direction, its first guide portion 21 moves up, and the position where the guide member 33 is connected to the first guide portion 21 gradually changes, that is, the guide member 33 slides on the first guide portion 21 along the third direction.

[0077] Exemplarily, the slide groove 300 is in a U-shaped shape. Figure 7 The lower die slider 31 is penetrated by the lower die slider 31 and the lower die slider 31 is penetrated by the lower die slider 31 along the first direction ( Figure 7 W direction shown in the middle) is concave.

[0078] Illustratively, when the mold is opened (ie after injection molding), the upper mold locking block 20 moves upward in the slide groove 300 along the height direction, and when the mold is closed (ie before injection molding), the upper mold locking block 20 moves downward in the slide groove 300 along the height direction.

[0079] For example, reference Figure 4 The two first guide portions 21 and the two adjacent groove walls (307, 308) have a set gap in the second direction to facilitate the upper mold locking block 20 to move up and down along the height direction.

[0080] The guide members 33 include two, and the two guide members 33 are connected to the two first guide portions 21 corresponding thereto.

[0081] refer to Figures 6 to 10 In some possible implementations, the first guide portion 21 includes a first guide plane 212, and the first guide plane 212 is along the first direction ( Figure 6 The guide member 33 includes a second guide plane 303, and the second guide plane 303 is along the fourth direction ( Fig. 9 The fourth direction is perpendicular to the third direction ( Fig. 9 shown in the Y direction).

[0082] For example, the first guide plane 212 and the second guide plane 303 are both rectangular, and the surface-to-surface connection between the two can better ensure the stability of the connection, so that the upper mold locking block 20 can move upward to drive the lower mold slider 31 along the mold opening direction ( Fig. 9The lower mold slider 31 then drives the pin slider 32 to move along the mold opening direction, so that the pin slider 32 is separated from the pin assembly.

[0083] refer to Figure 1 , Figure 4 , Figure 6 and Fig. 9 When the upper mold locking block 20 is embedded in the slide groove 300, the second guide plane 303 abuts against the first guide plane 212 at a position close to the upper end 210 (ie, Figure 4 As shown), when the upper die locking block 20 is in the slide groove 300 along the height direction ( Figure 4 The upper mold locking block 20 is moved upward (as shown in the Z direction), and the upward movement of the first guide portion 21 squeezes the guide member 33. As the first guide portion 21 moves upward, the position where the second guide plane 303 abuts against the first guide plane 212 gradually changes. The second guide plane 303 gradually approaches the lower end 211 from the original position close to the upper end 210, until finally the upper mold locking block 20 is completely separated from the slide groove 300, that is, at this time, the guide member 33 is also separated from the first guide portion 21.

[0084] The upper mold locking block 20 moves upward in the slide groove 300 along the height direction, so that the second guide plane 303 gradually approaches and separates from the lower end 211 from the original close to the upper end 210. It can be said that the guide member 33 moves relative to the bottom plate 11 along the mold opening direction ( Figure 1 That is, the upper mold locking block 20 drives the lower mold slide block 31 to move along the mold opening direction by its upward movement along the height direction, thereby realizing the mold opening.

[0085] refer to Figure 1 , Figure 8 and Fig. 9 In some possible implementations, the first guide portion 21 further includes a first abutting surface 213, which is perpendicular to the first guide plane 212; the guide member 33 further includes a second abutting surface 304, which is perpendicular to the second guide plane 303; the second abutting surface 304 can abut against the first abutting surface 213 along the second direction. That is, the abutment between the second abutting surface 304 and the first abutting surface 213 further ensures the stability of the connection between the first guide plane 212 and the second guide plane 303.

[0086] refer to Figures 6 to 9 The end portion 334 of the guide member 33 extending into the slide groove along the second direction can be elastically connected to the first abutting surface 213 of the first guide portion 21 .

[0087] For example, the upper die locking block 20 is arranged along the height direction ( Fig. 9During the downward movement of the first guide portion 21 (in the Z direction), the first abutting surface 213 of the first guide portion 21 will first contact the end portion 334 of the guide member 33, and the first abutting surface 213 will move along the second direction ( Fig. 9 The guide member 33 is squeezed by the first stop surface 213 (shown in the X direction) to make the end 334 of the guide member 33 flush with the groove wall of the slide groove 300 along the second direction, so as to facilitate the upper mold locking block 20 to be inserted into the slide groove 300. When the upper mold locking block 20 moves down to a suitable position, the first stop surface 213 no longer squeezes the guide member 33, and the guide member 33 can pop out to be partially exposed in the slide groove 300, so that the second guide plane 303 and the first guide plane 212 are connected in a close fit, so that the upper mold locking block 20 moves up to drive the lower mold slide block 31 to move along the mold opening direction.

[0088] refer to Figure 1 and Figure 6 In some possible implementations, the bottom plate 11 is provided with a through hole 110, and the through hole 110 is arranged along the height direction ( Figure 1 The through hole 110 is connected to the slide groove 300 (shown in the Z direction), and part of the upper mold locking block 20 can pass through the through hole 110 in the height direction. Exemplarily, the through hole 110 is connected to the slide groove 300 in the height direction to provide sufficient space for the upper mold locking block 20 to move up and down.

[0089] refer to Figure 6 and Figure 7 In some possible implementations, the limiting groove 310 includes a Figure 6 The pin slider 32 includes two convex portions 322 arranged opposite to each other along the second direction, and the two convex portions 322 are engaged with the two slots 311. Figure 6 The Z direction is shown in the figure) through the lower mold slider 31, along the first direction ( Figure 6 The mold body 31 is recessed in the lower mold slider 31 (as shown in the W direction) so that the first portion 320 of the pin slider 32 is embedded in the limiting groove 310, and the second portion 321 extends out along the first direction so that the pin assembly can be placed in the mold cavity 30 for injection molding.

[0090] The two slots 311 are arranged along the second direction ( Figure 7 The pin slider 32 is recessed in the lower mold slide 31 so that the protrusion 322 of the pin slider 32 is engaged with the slot 311, thereby fixing the pin slider 32 relative to the lower mold slide 31 in the first direction and the second direction, so that the lower mold slide 31 can drive the pin slider 32 to move along the mold opening direction ( Figure 6 Move in the direction of V.

[0091] refer to Figure 1 , Figure 7 and Fig.10In some possible implementations, a spherical groove 325 is provided on the surface of the pin slider 32 facing away from the mold cavity 30, and a portion of the stopper 320 can be moved along the mold closing direction ( Figure 7 The spherical groove 325 is inserted into the spherical groove 325 to limit the pin slider 32 in the height direction ( Figure 7 The spherical groove 325 is illustratively hemispherical.

[0092] The spherical groove 325 includes a first spherical groove 323 and a second spherical groove 324 spaced apart in the height direction, and the first spherical groove 323 and the second spherical groove 324 each include a first spherical groove 323 and a second spherical groove 324 spaced apart in the second direction ( Fig.10 The limiting member 320 includes a first limiting member 318 and a second limiting member 319 spaced apart along the second direction, and the first limiting member 318 and the second limiting member 319 are elastically abutted against the two first spherical grooves 323 or the two second spherical grooves 324.

[0093] That is, the surface of the pin slider 32 facing away from the mold cavity 30 is provided with four spherical grooves, namely two first spherical grooves 323 and two second spherical grooves 324, wherein the spherical grooves 324 are arranged along the height direction ( Fig.10 The two first spherical grooves 323 are close to the lower end of the pin slider 32, and the two second spherical grooves 324 are close to the upper end of the pin slider 32. When the mold is closed, the pin slider 32 is not lifted by the top pressing member 4. At this time, the first stopper 318 and the second stopper 319 elastically abut against the two second spherical grooves 324. When the top pressing member 4 lifts the pin slider 32 and moves the pin slider 32 to the highest position in the height direction, the first stopper 318 and the second stopper 319 abut against the two first spherical grooves 323, and then the top pressing member 4 is reset. The pin slider 32 relies on its engagement with the stopper groove 310 and the action of the first stopper 318 and the second stopper 319, and it can still maintain a state higher than the upper surface of the lower mold slider 31.

[0094] Exemplarily, the lower mold slide 31 is moved in the mold opening direction ( Figure 7 The end surface 3100 on one side of the V direction is provided with a first direction ( Figure 7 The first through hole 316 extending from the limit groove 310 in the W direction is used to accommodate the first limit member 318. The groove wall 306 of the slide groove 300 along the first direction is provided with a second through hole 317 extending along the first direction, and the second through hole 317 is used to accommodate the second limit member 319.

[0095] Both the first limit member 318 and the second limit member 319 are elastic, that is, the first limit member 318 and the second limit member 319 will retract into the first through hole 316 and the second through hole 317 under the pressure of external force, and when the external force is removed, the first limit member 318 and the second limit member 319 will pop out from their respective holes to abut the pin slider 32.

[0096] refer to Figures 1 to 3 as well as Figure 7 In some possible implementations, the slide groove 300 is along the first direction ( Figure 7 The groove wall 306 (shown in the W direction) is the first locking surface 305, and the upper mold locking block 20 is along the first direction ( Figure 2 The first locking surface 305 and the second locking surface 204 are arranged along the third direction ( Figure 7 For example, the first locking surface 305 and the second locking surface 204 are attached together along the first direction, thereby forming the upper mold locking block 20 pressing the lower mold slide 31 in the first direction, limiting the movement of the lower mold slide 31 in the first direction.

[0097] refer to Figure 4 , Figure 7 and Fig.10 In some possible implementations, the slide groove 300 is along the second direction ( Figure 6 The two groove walls (307, 308) are respectively provided with mounting holes 309 extending in the second direction, and the mounting holes 309 are used to install the guide member 33. That is, a part of the guide member 33 is located in the mounting hole 309, and the other part extends out of the mounting hole 309 in the second direction, thereby abutting against the first guide portion 21, so that the upper mold locking block 20 moves upward to drive the lower mold slide 31 in the mold opening direction ( Fig.10 Movement of the device (in the direction of V).

[0098] refer to Figure 8 , Fig.11 and Fig.12 In some possible implementations, the guide member 33 includes a first limiting surface 330, the mounting hole 309 includes a second limiting surface 3090, and the first limiting surface 330 and the second limiting surface 3090 are connected along the second direction ( Fig.12 The second limiting surface 3090 abuts against the first limiting surface 330 of the guide member 33 along the second direction, thereby limiting the guide member 33 in the second direction and in the direction toward the slide slot, and preventing the guide member 33 from sliding out of the mounting hole 309 in the second direction and in the direction toward the slide slot.

[0099] In some possible implementations, the mounting hole 309 includes a first hole 3091 and a second hole 3092 that are connected, and the aperture of the first hole 3091 is smaller than the aperture of the second hole 3092, so as to form a second limiting surface 3090 at the connection between the first hole 3091 and the second hole 3092. That is, the radial spacing between the first hole 3091 and the second hole 3092 forms the second limiting surface 3090.

[0100] The guide member 33 includes a first cylindrical member 331 and a second cylindrical member 332 connected to each other, wherein the radial dimension of the first cylindrical member 331 is smaller than the radial dimension of the second cylindrical member 332, so as to form a first limiting surface 330 at the connection between the first cylindrical member 331 and the second cylindrical member 332. That is, the radial spacing between the first cylindrical member 331 and the second cylindrical member 332 forms the first limiting surface 330 which is arranged opposite to the second limiting surface 3090 along the second direction. The first hole 3091 is used to accommodate the first cylindrical member 331, and the second hole 3092 is used to accommodate the second cylindrical member 332.

[0101] In some possible implementations, a first anti-rotation portion 3093 is provided in the second hole 3092, a second anti-rotation portion 333 is provided on the outer wall of the second cylindrical member 332, and the first anti-rotation portion 3093 is fitted and connected with the second anti-rotation portion 333. Exemplarily, the mounting hole 309 and the guide member 33 are both cylindrical, the first anti-rotation portion 3093 and the second anti-rotation portion 333 are both flat, and the surface-to-surface fit between the two effectively prevents the guide member 33 from rotating in the mounting hole 309, thereby preventing the rotation of the guide member 33 from affecting the upper mold locking block 20 driving the lower mold slide 31 along the mold opening direction ( Fig.12 Move in the direction of V.

[0102] In some possible implementations, the second hole 3092 is disposed along the second direction ( Fig.11 The hole 3094 in the direction away from the first hole 3091 (shown in the X direction) is provided with a blocking member 6 to limit the guide member 33 from sliding out of the hole 3094 of the second hole 3092 along the second direction. That is, the blocking member 6 blocks the guide member 33 to prevent the guide member 33 from sliding out of the second hole 3092 along the second direction, causing the upper mold locking block 20 to be unable to drive the lower mold slide block 31 along the mold opening direction ( Fig.12 Move in the direction of V.

[0103] In some possible implementations, the lower mold slide 31 is moved in the first direction ( Fig.11A groove 312 is provided on the side wall of the second hole 3092 (shown in the X direction) and close to the opening 3094 of the second hole 3092. The groove 312 extends along the second direction and communicates with the second hole 3092. The groove 312 is used to embed the blocking member 6. Exemplarily, the blocking member 6 is embedded in the groove 312 along the second direction to form a block on the opening 3094 of the second hole 3092, so as to prevent the guide member 33 from sliding out of the second hole 3092 from the opening 3094 of the second hole 3092.

[0104] Optionally, the blocking member 6 is in the shape of a racetrack circle, and correspondingly, the groove 312 is in the shape of a racetrack circle.

[0105] In some possible implementations, the notch area of ​​the groove 312 is larger than the orifice area of ​​the second hole 3092, and the groove 312 is disposed along the second direction ( Fig.11 A screw hole 313 is provided on the groove wall (shown in the X direction), and the screw hole 313 and the second hole 3092 are arranged in the height direction ( Fig.11 The blocking member 6 is fixedly connected to the lower die slide 31 by screws 7. That is, the blocking member 6 is fixed to the lower die slide 31 by screws 7 on the basis of being clamped in the groove 312, thereby ensuring the relative fixation of the blocking member 6 and further ensuring the limiting effect of the blocking member 6 on the guide member 33.

[0106] Exemplarily, the connection between the blocking member 6 and the lower die slide 31 is a detachable connection, thereby facilitating the replacement of the worn guide member 33 .
