Description

Technical Field

[0001] This application relates to the field of injection molding technology, and in particular to an auxiliary demolding fixture for a sliding plate. Background Technology

[0002] In injection molding technology, the demolding fixture is an important component of the mold. Its function is to safely and efficiently remove the cooled and solidified product from the mold cavity or core after injection molding, while avoiding product deformation or damage.

[0003] Reference Figure 1 , Figure 2 and Figure 3 The existing sliding piece 1 is fixedly connected to the injection molded part 2 after injection molding. The sliding piece 1 is fixed in the mold by a mounting fixture. After injection molding is completed, the mounting fixture is first removed from the mold, and then the sliding piece 1 is removed from the mounting fixture. The mounting fixture for the sliding piece 1 includes a mounting box 3, a first clamping block 4, a mounting block 5, a second clamping block 6, and a limiting rod 7. The mounting box 3 is located on a horizontal plane and has a mounting groove 8. The first clamping block 4 and the second clamping block 6 are located at the two ends of the mounting groove 8 on the mounting box 3, respectively. The mounting block 5 is located in the middle of the first clamping block 4 and the second clamping block 6. The first clamping block 4, the mounting block 5, and the second clamping block 6 clamp and fix the sliding piece 1. The limiting rod 7 slides in the mounting block 5 and passes through the sliding piece 1 to fix the position of the sliding piece 1.

[0004] After injection molding is complete, the first clamping block, the second clamping block, and the mounting block need to be removed from the mounting slot of the mounting box, and then the sliding piece can be taken out to retrieve the injection-molded part. However, after injection molding, the surface temperature of the mounting fixture is high, and it needs to be cooled before retrieval. At the same time, because the first clamping block, the second clamping block, and the mounting block are embedded in the mounting slot of the mounting box, it is inconvenient for workers to replace or install them, reducing work efficiency. Utility Model Content

[0005] In order to facilitate the smooth demolding of the slide after injection molding and improve work efficiency, this application provides an auxiliary demolding fixture for the slide.

[0006] The auxiliary demolding fixture for a sliding plate provided in this application adopts the following technical solution:

[0007] An auxiliary demolding fixture for a sliding plate includes a demolding pressure plate and a demolding base. The demolding base has multiple limiting blocks inside, and the demolding pressure plate has a push rod inside. An installation box is placed on the demolding base, and the multiple limiting blocks limit the installation box. The top end of the push rod passes through the installation box and abuts against a first clamping block or a second clamping block. When the demolding pressure plate is placed on the demolding base, the demolding pressure plate presses down on the installation box, and the installation box slides downward, causing the first clamping block, the installation block, and the second clamping block to slide out of the installation box.

[0008] By adopting the above technical solution, when the demolding base is placed on the mounting box, the push rod passes through the mounting box and abuts against the bottom of the first clamping block or the second clamping block. When the demolding pressure plate is installed on the demolding base, the push rod abuts against the first clamping block or the second clamping block and prevents the first clamping block, the mounting block and the second clamping block from moving. Then the demolding pressure plate presses down on the mounting box, causing the first clamping block, the second clamping block and the mounting block to slide out of the mounting box, thereby facilitating the removal of the sliding piece from the mounting fixture.

[0009] Preferably, three limiting blocks are provided, and the three limiting blocks abut against the inner wall of the demolding base and the four sides of the mounting box.

[0010] By adopting the above technical solution, three limiting blocks are located on the inner side wall of the demolding base, and the three limiting blocks cooperate with one side wall of the demolding base to achieve abutment on all four sides of the mounting box. When the demolding plate is pressed down, the three limiting blocks and the inner side wall of the demolding base guide the sliding of the mounting box, thereby facilitating the sliding of the first clamping block, the second clamping block and the mounting block out of the mounting box.

[0011] Preferably, there are two push rods, and the top ends of the two push rods respectively abut against the first clamping block and the second clamping block.

[0012] By adopting the above technical solution, the two push rods abut against the bottom of the first clamping block and the second clamping block respectively, so that neither the first clamping block nor the second clamping block will move, thereby facilitating the sliding of the first clamping block, the second clamping block and the mounting block out of the mounting box.

[0013] Preferably, a first pressing block and a third pressing block are formed on the bottom wall of the demolding plate, and the first pressing block and the third pressing block respectively abut against the top walls at both ends of the mounting box in the length direction.

[0014] By adopting the above technical solution, when the demolding plate is installed on the demolding base, the first pressure block and the third pressure block abut against the two ends of the mounting box in the length direction, and push the mounting box to slide downward.

[0015] Preferably, a second pressing block is formed on the bottom wall of the demolding plate, and the second pressing block abuts against the top of the limiting rod.

[0016] By adopting the above technical solution, when the first and third pressure blocks press down and push the mounting box downward, the second pressure block abuts against and pushes the limiting rod downward. Since one end of the limiting rod is inserted into the injection molded part, when the limiting rod moves downward, the limiting rod separates from the injection molded part, making it easier to pull the injection molded part out of the limiting rod and improving work efficiency.

[0017] Preferably, the top of the demolding base is provided with a guide groove, and the bottom of the demolding pressure plate is provided with a guide post, which is inserted into the guide groove.

[0018] By adopting the above technical solution, the guide post at the bottom of the demolding plate and the guide groove at the top of the demolding base correspond to each other, making it easier for the demolding plate to be inserted into the demolding base and facilitating the operation of the staff.

[0019] Preferably, the top of the demolding plate is provided with a handle.

[0020] By adopting the above technical solution, the handle on the demolding plate makes it easy for operators to pick up, transport and move the auxiliary demolding fixture of the slide.

[0021] Preferably, the demolding base is provided with a base plate, and the top wall of the base plate abuts against the bottom wall of the demolding base.

[0022] By adopting the above technical solution, the installation of the base plate increases the contact area between the auxiliary demolding fixture of the sliding plate and the horizontal surface, which facilitates the improvement of the structural stability of the fixture.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Using a demolding plate, when a demolding base is placed on the mounting box, the ejector rod passes through the mounting box and abuts against the bottom of the first or second clamping block. When the demolding plate is installed on the demolding base, the ejector rod abuts against the first or second clamping block, preventing the first clamping block, mounting block, and second clamping block from moving. Then, the demolding plate presses down on the mounting box, causing the first clamping block, second clamping block, and mounting block to slide out of the mounting box, thus facilitating the removal of the sliding piece from the mounting fixture.

[0025] 2. With the help of three limiting blocks, which are located on the inner side wall of the demolding base and cooperate with one side wall of the demolding base, the three limiting blocks abut against the four sides of the mounting box. When the demolding plate is pressed down, the three limiting blocks and the inner side wall of the demolding base guide the sliding of the mounting box, thereby facilitating the sliding of the first clamping block, the second clamping block and the mounting block out of the mounting box.

[0026] 3. Two push rods are used to abut against the bottom of the first clamping block and the second clamping block respectively, so that the first clamping block and the second clamping block will not move, thus facilitating the sliding out of the first clamping block, the second clamping block and the mounting block from the mounting box.

[0036] The following is in conjunction with the appendix Figures 4-8 This application will be described in further detail.

[0037] This application discloses an auxiliary demolding fixture for a sliding plate.

[0038] Reference Figure 4 and Figure 5 An auxiliary demolding fixture for a sliding plate includes a demolding pressure plate 9 and a demolding base 16. The demolding base 16 has a U-shaped design. A base plate 18 is fixedly installed on the bottom of the demolding base 16 by bolts. The base plate 18 is placed on a horizontal surface. The bottom wall of the demolding base 16 abuts against the top wall of the base plate 18, thereby increasing the contact area between the auxiliary demolding fixture for the sliding plate and the horizontal surface and improving the stability of the fixture.

[0039] The demolding base 16 has four guide grooves 17, with each pair of guide grooves 17 located at one end of the top wall of the demolding base 16, and the four guide grooves 17 are symmetrically arranged along the width direction of the demolding base 16.

[0040] The demolding base 16 is equipped with six limiting blocks 19, which are arranged diagonally from left to right. Four ejector pins 20 are installed inside the demolding base 16. Each station consists of three limiting blocks 19 and two ejector pins 20, with the two ejector pins 20 located inside the three limiting blocks 19 in each station.

[0041] A handle 10 is installed on the demolding plate 9. The handle 10 is located on the top wall of the demolding plate 9, which makes it easy for the operator to pick up and move the auxiliary demolding fixture of the slide.

[0042] Four guide pillars 15 are fixedly installed on the demolding plate 9. Each pair of guide pillars 15 is located at one end of the bottom wall of the demolding plate 9, and the four guide pillars 15 are symmetrically arranged along the width direction of the demolding plate 9. The positions of the four guide grooves 17 correspond one-to-one with the positions of the four guide pillars 15.

[0043] Reference Figure 6 Two sets of first pressing blocks 21 and third pressing blocks 23 are formed on the bottom wall of the demolding plate 9. The two sets of first pressing blocks 21 and third pressing blocks 23 respectively abut against the two ends of the two mounting boxes 3 in the length direction. Two sets of second pressing blocks 22 are formed on the bottom wall of the demolding plate 9. The two sets of second pressing blocks 22 are located on the bottom wall of the demolding plate 9 and abut against the limiting rods 7 of the two mounting boxes 3 respectively.

[0044] The implementation principle of the auxiliary demolding fixture for the sliding plate in this application embodiment is as follows: When the injection molding work is completed, the two mounting boxes 3 are first placed into the two stations of the demolding base 16. The three limiting blocks 19 in each station and one inner side wall of the demolding base 16 abut against the four sides of the mounting box 3 for limiting (refer to...). Figure 5 At this time, the two push rods 20 in each station abut against the bottom of the first clamping block 4 and the second clamping block 6 respectively (refer to...). Figure 7 The operator presses the demolding plate 9 downward by holding the handle 10. The insertion of the guide post 15 and the guide groove 17 guides the installation of the auxiliary demolding fixture for the sliding plate.

[0045] When the demolding plate 9 presses down, the four push rods 20 abut against the two first clamping blocks 4 and the second clamping block 6, preventing the first clamping blocks 4 and the second clamping block 6 from moving. The demolding plate 9 drives the first pressing block 21 and the third pressing block 23 to abut against both ends of the mounting box 3 along its length, and pushes the mounting box 3 to slide downward, causing the first clamping block 4, the mounting block 5, and the second clamping block 6 to slide out of the mounting box 3 (see reference). Figure 8 This facilitates the removal of the sliding plate from the mounting fixture.

[0046] The second pressure block 22 then abuts against and pushes the limiting rod 7 downward. Since one end of the limiting rod 7 is inserted into the injection molded part 2, when the limiting rod 7 moves downward, the limiting rod 7 separates from the injection molded part 2. The top of the limiting rod 7 is a sharp corner, which makes it easy to pull the injection molded part 2 out of the limiting rod 7, thus improving work efficiency.

[0047] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
