Description
TECHNICAL FIELD
[0001] The present application relates to the field of automobile carpet forming mold, in particular to a deformation nail frame of a one-out-two carpet forming mold, which is used to realize stable forming of two carpet products at a time and solve the problems of product hair consistency and subsequent separation. BACKGROUND
[0002] In the production process of automobile carpet, the deformation nail frame is a core component for fixing the carpet raw material and assisting the mold to complete the pressing forming. The applicant has previously applied for a patent (Patent No. 202010181031.7) for a carpet forming mold deformation nail frame, which can realize stable forming of a single carpet. However, with the increasing demand for production efficiency in the industry, the existing technology gradually exposes obvious limitations: The current industry generally uses a "one-out-two" carpet forming mold (i.e., a mold that produces two carpet products at a time) to improve production efficiency. However, the existing deformation nail frame can only adapt to single product production and cannot match the symmetrical arrangement structure of the one-out-two mold. If the existing deformation nail frame is forcibly applied to the one-out-two mold, since the two forming cavities in the mold are arranged symmetrically, the carpet raw material will be arranged in opposite directions during the forming process, resulting in two products with opposite hair directions. The opposite hair direction will seriously affect the appearance and texture of the carpet (such as inconsistent light reflection) and the user experience (such as different friction feeling), which does not meet the product quality requirements.
[0003] In addition, even if the existing technology can achieve one-out-two forming, the two carpet products often have local connection areas due to the connection of the raw materials during the forming process, and an additional "separation process" is required to separate them after they are taken out of the mold. This process not only increases the production time (20-30 seconds are required for single separation) and labor cost, but also may cause damage to the edges of the carpet (damage rate of about 5%-8%) during the separation process, significantly reducing the product pass rate.
[0004] Therefore, there is an urgent need for a deformation nail frame technology that can adapt to a one-out-two carpet forming mold, solve the problem of inconsistent hair direction, and eliminate the need for subsequent separation, in order to overcome the shortcomings of existing technology and meet the needs of mass production and high-quality production of automobile carpets. SUMMARY
[0005] I. Technical problems to be solved The present application aims to solve the following core technical problems in view of the shortcomings of the existing technology: The existing deformation nail frame cannot match the symmetrical arrangement structure of the one-out-two carpet forming mold, making it difficult to realize simultaneous production of two products at a time; In the one-out-two production scenario, the two carpet products have opposite hair directions due to the symmetrical arrangement of the mold, which does not meet the product quality requirements; The existing one-out-two forming scheme needs to additionally increase the parting process, which not only increases the production cost, but also easily causes product damage and reduces the qualified rate.
[0006] II. Technical solutions to solve the problems To achieve the above object, the application provides a one-out-two carpet forming mold deformation nail frame, and the specific technical solutions are as follows: A one-out-two carpet forming mold deformation nail frame, comprising an outer frame, a deformation inner frame and a material nail, the outer frame is set as a rectangular frame, the deformation inner frame is movably installed inside the outer frame, and the deformation inner frame is uniformly provided with the material nail on the upper surface, the material nail is used for hooking and fixing the carpet raw material, and the position of the raw material is ensured to be stable during the forming process.
[0007] The deformation inner frame is a core structure for realizing the one-out-two forming and the hair direction control, and comprises a fixed frame, a first deformation frame, a second deformation frame, a middle floating frame and a V-shaped rotary arm. The two short sides of the inner side of the outer frame are respectively provided with a fixed frame as the basic support structure of the deformation inner frame. The two ends of the two fixed frames are respectively rotatably connected to one end of a first deformation frame, the other end of the four first deformation frames is rotatably connected to one end of a second deformation frame, and the other end of the four second deformation frames is telescopically connected to the two ends of the middle floating frame - through the rotation and telescopic cooperation between the frames, the arching and resetting of the deformation inner frame are realized. One side of the V-shaped rotary arm is fixed to the outer side of the first deformation frame, and the root of the V-shaped rotary arm is also rotatably connected to one end of the fixed frame - the V-shaped rotary arm serves as a power transmission component and can drive the first deformation frame to rotate under the action of external pressure, thereby driving the deformation of the entire deformation inner frame. The middle floating frame is set as an I-shaped frame, which can separate the deformation inner frame into two independent forming areas corresponding to the two product cavities of the one-out-two mold, so that the two carpet products do not interfere with each other during the forming process and do not need to be subsequently parted.
[0008] The second deformation frame is a key component for realizing the telescopic function, and comprises a sleeve, a guide rod, a connecting pipe and a tension spring. The two ends of the sleeve are respectively provided with guide sleeves, one end of the connecting pipe is rotatably connected to the other end of the first deformation frame, the other end of the connecting pipe is provided with a guide rod, and the two ends of the middle floating frame are respectively provided with a guide rod. The guide rods of the connecting pipe and the middle floating frame are respectively slidably inserted into the guide sleeves at the two ends of the sleeve, forming a telescopic sliding fit. The two ends of the sleeve are also elastically connected to the corresponding positions of the other end of the connecting pipe and the two ends of the middle floating frame through the tension spring - the tension spring can provide a back pull force when the deformation inner frame is reset, so that the frame structure returns to the initial horizontal state.
[0009] To further improve the forming precision and stability, the application also includes the following auxiliary structure: Limiting rod: two limiting rods are respectively installed on the outer side of the upper die of the one-out-two carpet forming die, the upper die frame near the corner position of the upper die is installed, and the lower end is pressed on the upper surface of the two end frames of the outer frame. The limiting rod can limit the downward distance of the upper die to avoid excessive deformation of the deformed inner frame.
[0010] Top rod: four top rods are respectively installed at the four corner positions of the outer side of the upper die of the carpet forming die, and the lower end of the top rod is pressed on the upper end of the other side of the V-shaped rotating arm. When the upper die is lowered, the top rod can apply pressure to the V-shaped rotating arm to drive the V-shaped rotating arm to rotate, thereby driving the deformed inner frame to arch. The lower end of the top rod can be designed to install a guide wheel, which can press the V-shaped cantilever through the guide wheel to avoid damage to the contact position, reduce friction, and prolong the service life. The contact surface between the V-shaped rotating arm and the top rod is designed as a horizontal surface, and the guide wheel is convenient to work with the horizontal surface.
[0011] Anti-rotation positioning structure: the sleeve has a waist-shaped hole on both sides of the two ends, and the head of the guide rod has a positioning pin on both sides, which is slidably located in the corresponding waist-shaped hole. The positioning pin and the waist-shaped hole cooperate to prevent the sleeve from rotating and ensure the stability of the sliding direction of the guide rod. At the same time, the outer sides of the two ends of the connecting pipe and the intermediate floating frame are connected to the anti-rotation plates, and the other end of the anti-rotation plate is slidably located on the outer side of the end of the sleeve, and a U-shaped groove is designed in the middle (for avoiding the convex column). The anti-rotation plate and the positioning pin work together to further prevent the sleeve from rotating and avoid the positioning pin from breaking due to excessive unilateral stress, thereby prolonging the service life of the component.
[0012] Guide assembly: the guide assembly includes a guide block, a guide cylinder, a guide rod, a guide wheel, a guide wheel seat, a positioning plate, and a positioning rod. The guide block is installed at the lower end of the intermediate floating frame (with a V-shaped groove at the lower end), the guide cylinder is installed below the guide block, the extension end of the guide cylinder is connected to the guide rod, and the guide wheel is installed on the top of the guide rod through the guide wheel seat. When the guide cylinder drives the guide rod to move upward, the guide wheel first contacts the side wall of the V-shaped groove. If the nail frame is offset, the guide wheel will push the guide block left and right to adjust until the guide wheel is on the middle of the groove bottom, achieving accurate guidance of the nail frame, preventing forming deviation caused by inconsistent stretching deformation of the carpet material, and avoiding interference of the material nails on the intermediate floating frame with the edge of the upper die.
[0013] Upper and lower guide blocks: the intermediate floating frame is designed with upper guide blocks on the left and right sides near the end of the two ends (the outer side is an inclined surface, forming an outer conical structure), and the lower guide blocks are designed on the left and right sides of the gap between the lower part of the lower die (the outer side is an inclined surface, forming an inner conical structure). Before the mold is closed, the upper guide block and the lower guide block are tangent to each other and slide together, which can further guide the position of the nail frame, prevent the nail frame from shaking left and right, and ensure the accuracy of the mold closing and the stability of the pressure maintaining.
[0014] In addition, the upper die of the one-out-two carpet forming die is designed with four die cavities (two on the left side as a group and two on the right side as a group), and the lower die is correspondingly designed with the left two protruding dies and the right two protruding dies; the upper gap is reserved between the left and right die cavities (to avoid the middle floating frame upper material peg), and the lower gap is reserved between the left and right protruding dies (to avoid the middle floating frame lower part) - the structure design can ensure that the deformed peg frame is perfectly matched with the die, and part interference is avoided.
[0015] III. Method of use The method of use of the present application is as follows, and can be more clearly understood in combination with the drawings: Step one, material preparation and preheating: two pieces of automotive interior carpet material are respectively hooked on the two independent forming areas of the deformed inner frame (two sides separated by the middle floating frame), at this time the peg frame is in a non-deformed horizontal state; the key is to ensure that the two pieces of carpet material are placed with the nap in opposite directions (for example, the left side carpet material nap is directed to the left, and the right side carpet material nap is directed to the right), and the nap direction of the two products after subsequent forming can be kept consistent; according to the characteristics of the carpet raw material, the peg frame and the carpet material are heated to a set temperature (usually 80-120°C, which is adjusted according to the material quality), to improve the plasticity of the raw material.
[0016] Step two, peg frame conveying and deformation opening: the peg frame with heated carpet material is conveyed through the track to between the upper and lower dies of the one-out-two carpet forming die; the upper die starts to descend, and the limit rods on the outside of the upper die are only located at one end of the upper surface of the outer frame at the initial stage, without exerting pressure; as the upper die continues to descend, the top rods at the four corners of the upper die gradually contact and press the upper end of the other side arm of the V-shaped rotary arm, the V-shaped rotary arm rotates around the root, and the first deformed frame is raised upward from the horizontal state; the first deformed frame rotates to pull the connecting pipe of the second deformed frame, the connecting pipe drives the guide rod to slide along the sleeve guide sleeve, and overcomes the tension of the tension spring to stretch the second deformed frame; until the four limit rods completely press against the upper surface of the two ends of the outer frame, the deformed inner frame stops arching, at this time the peg frame is completely opened, forming a profiled structure that is adapted to the die cavity.
[0017] Step three, precise alignment and die closing: after the peg frame is completely opened, the upper die continues to descend with the peg frame; the alignment cylinder of the alignment assembly is started, driving the alignment rod to ascend, and the guide wheel at the top of the alignment rod first contacts the V-shaped groove of the alignment block - if the peg frame has left and right deviation, the guide wheel will push the alignment block (and the middle floating frame) to left and right translation adjustment under the guidance of the side wall of the V-shaped groove, until the guide wheel rolls and stops in the middle position of the groove bottom of the V-shaped groove, completing the precise alignment of the peg frame; at the same time, the upper guide block of the middle floating frame contacts and slides tangentially with the lower guide block of the lower die, further aligning the position of the peg frame to prevent left and right shaking; then the upper die continues to descend until it closes with the lower die.
[0018] Step four, pressure maintaining forming: after the die is closed, the pressure maintaining time is set according to the product requirements (usually 30-60 seconds), so that the carpet raw material is fully shaped in the die cavity, forming a product that meets the specifications.
[0019] Step five, mold opening and part taking: after the pressure holding is completed, the upper mold starts to go up; when it goes up to the top rod no longer acts on the V-shaped rotating arm, the deformed inner frame gradually resets under the back pulling force of the tension spring - the first deformed edge frame rotates downward, and the guide rod of the second deformed edge frame slides and shrinks along the sleeve guide sleeve until the deformed inner frame returns to the horizontal state; during the resetting process, the material nails and the carpet products are preliminarily separated, which facilitates the subsequent manual taking of the two independent carpet products from the nail frame without the need for an additional part separation process. Advantages
[0020] Compared with the prior art, the present application has the following significant advantages: Adapting to a two-out-one mold to improve production efficiency: the deformed inner frame is divided into two independent forming areas by the I-shaped intermediate floating frame, perfectly matching the symmetrical arrangement of the two-out-one mold, realizing the synchronous production of two carpet products at a time, and improving the production efficiency by 100% compared with single piece forming, meeting the batch production demand.
[0021] Solve the problem of inconsistent hair direction and ensure product quality: when in use, place the two pieces of carpet in opposite directions, and combine the symmetrical arrangement of the mold, so that the hair direction of the two products formed is completely consistent, avoiding the appearance and feel difference caused by opposite hair direction, and improving the product pass rate to more than 99%.
[0022] No need for subsequent part separation, reducing production cost: the independent forming areas separated by the intermediate floating frame make the two products formed not connected to each other, which can be used directly after being taken out of the mold, saving the part separation process in the traditional scheme, and saving 30-60 minutes of production time for each batch of products, while avoiding edge damage caused by part separation, reducing raw material waste and labor cost.
[0023] High forming precision and strong stability: through the cooperative action of the guide assembly, the upper and lower guide blocks, and the anti-rotation positioning structure, accurate positioning and deformation control of the nail frame can be realized, the dimensional error of the formed product is ≤±0.5mm, and the hair direction consistency and surface flatness are better than those of the prior art; the cooperation of the tension spring and the top rod makes the deformation and resetting process smooth, and the service life of the parts is prolonged by more than 30%.
