Description

Technical Field

[0001] This invention relates to the field of mold technology, specifically to an anti-wrinkle mechanism for GMT molding process. Background Technology

[0002] A mold is a tool used to shape a blank into a part with a specific shape and size under the action of external force. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics, and other products. A mold has a specific contour or internal cavity shape. Using a contour shape with cutting edges allows the blank to be separated along the contour line (blanking). Using the internal cavity shape allows the blank to obtain a corresponding three-dimensional shape. A mold generally consists of two parts: a moving mold and a fixed mold (or a punch and a die), which can be separated and joined. When separated, the part is removed; when joined, the blank is injected into the mold cavity for shaping. Molds are precision tools with complex shapes, bearing the expansion force of the blank. They have high requirements for structural strength, rigidity, surface hardness, surface roughness, and machining accuracy. The development level of mold manufacturing is one of the important indicators of the level of mechanical manufacturing.

[0003] There are certain defects in the production process of GMT molds. For example, due to the production process of the product parts, wrinkles are easily generated during production, which leads to poor product quality and failure to meet the usage requirements. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-wrinkle mechanism for GMT molding process, which can solve the problem of wrinkles easily generated in products during the production process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a GMT molding process anti-wrinkle mechanism, comprising a GMT mold assembly, wherein the GMT mold assembly includes an upper mold assembly and a lower mold assembly;

[0006] The upper mold assembly includes an upper mold body. Side protrusions are fixedly provided on two opposite sides of the upper mold body by fastening screws. A pressure protrusion is fixedly provided at the bottom of the side protrusions. The fastening screws have a first position limiting groove at the installation position of the side protrusions.

[0007] The lower mold assembly includes a lower side protrusion. A pressing groove is formed on the top surface of the lower side protrusion. A second position limiting groove is formed at the lower end of the surface of the lower side protrusion. Two fixing protrusions are fixed on the lower side surface of the lower side protrusion. A lower limiting screw is sleeved on the surface of each fixing protrusion and is threadedly connected to the lower side protrusion. A limiting spring is provided between the lower side protrusion and the fixing protrusion and outside the lower limiting screw.

[0008] Preferably, the pressing bump and the pressing groove are adapted to each other, and the profiles of the pressing groove and the pressing bump are adapted to the profiles of the GMT mold assembly.

[0009] Preferably, the second position limiting groove on the lower protrusion is also fastened to the lower mold body by fastening screws.

[0010] Preferably, the opening length of the second position limiting groove is greater than the pre-press stroke after the GMT mold assembly is pressed down.

[0011] Preferably, the lower protrusion is a T-shaped structural component, and the limiting springs are disposed at the bottom of both ends of the lower protrusion and are arranged symmetrically.

[0012] Preferably, the corners of the lower protrusion and the side protrusion are chamfered.

[0013] Preferably, the lateral area of ​​the fixing protrusion is greater than the maximum diameter of the limiting spring, and the fixing protrusion is positioned to correspond to the bottom ends of the lower protrusion.

[0014] Preferably, a limiting groove is fixedly provided on the end face of the upper mold body, and a pressure ring is elastically and movably provided in the limiting groove, with a pressure rib provided at the middle position of the surface of the pressure ring.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. This invention places the product to be molded between the upper mold assembly and the lower mold assembly, and the two assemblies are closed. The product first contacts the pressure rib on the pressure ring, and the pressure ring pre-presses it. At the same time, the pressure protrusion on the side protrusion contacts the pressure groove on the lower side protrusion to fix the two sides of the product. The limiting spring provides a certain elastic constraint to ensure that the product will not wrinkle. This solves the problem that wrinkles are easily generated in the product during production due to the manufacturing process of the product, which leads to poor product quality and failure to meet the usage requirements.

[0017] 2. This invention uses an auxiliary cleaning component to clean the surface of the GMT mold assembly and the auxiliary cleaning component during the production process, preventing dust and debris from affecting the product quality. Specifically, it includes a guide rail, a drive motor, a cleaning brush, and a hydraulic rod, which enable it to clean the surface of the mold. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-6 As shown, a wrinkle-resistant mechanism for GMT molding process includes a GMT mold assembly 1, which includes an upper mold assembly 11 and a lower mold assembly 12. The upper mold assembly 11 and the lower mold assembly 12 are mutually adapted to form a better assembly gap and ensure product manufacturing quality.

[0027] The upper mold assembly 11 includes an upper mold body 111. Side protrusions 116 are fixedly provided on two opposite sides of the upper mold body 111 by fastening screws 117. A pressure protrusion 115 is fixedly provided at the bottom of the side protrusions 116. The fastening screws 117 have a first position limiting groove 118 at the installation position of the side protrusions 116. There are two first position limiting grooves 118 on the side protrusions 116, and the first position limiting grooves 118 and the fastening screws 117 are compatible to ensure the compatibility of the fastening screws 117 installation. At the same time, the angle of the pressure protrusion 115 is compatible with the upper mold assembly 11 and the lower mold assembly 12.

[0028] The lower mold assembly 12 includes a lower protrusion 122. A pressing groove 128 is formed on the top surface of the lower protrusion 122, which is compatible with the upper pressing protrusion 115. A second position limiting groove 123 is formed at the lower end of the surface of the lower protrusion 122. The limiting groove 112 is fixed by a fastening screw 117, which is installed in the second position limiting groove 123. Two fixing protrusions 127 are fixed on the lower surface of the lower protrusion 122. A lower limiting screw 125 is fitted onto the surface of each fixing protrusion 127. Block 127 is used to limit the position of the limiting spring 126 and to allow the limiting spring 126 to form downward pressure. The lower limiting screw 125 is threadedly connected to the lower protrusion 122. The limiting spring 126 is provided between the lower protrusion 122 and the fixed protrusion 127 and outside the lower limiting screw 125. The lower limiting screw 125 guides the downward deformation of the limiting spring 126 and prevents it from displacing. The pressure protrusion 115 and the pressure groove 128 are adapted to each other, and the profiles of the pressure groove 128 and the pressure protrusion 115 are adapted to the profiles of the GMT mold assembly 1.

[0029] The opening length of the second position limiting groove 123 is greater than the pre-press stroke after the GMT mold assembly 1 is pressed down. This is to ensure the overall pressing stroke and ensure the product molding.

[0030] The lower protrusion 122 is a T-shaped structural component. The limiting spring 126 is set at the bottom of both ends of the lower protrusion 122 and is symmetrically arranged. The T-shaped structural component design reduces the actual size of the product, reduces costs, and makes reasonable use of the structure.

[0031] Both the lower protrusion 122 and the side protrusion 116 have chamfered corners to prevent injury to structural components, products, or people.

[0032] The lateral area of ​​the fixed protrusion 127 is larger than the maximum diameter of the limiting spring 126. This is to ensure the contact area of ​​the limiting spring 126, thereby ensuring the effectiveness of the lower limiting screw 125. The fixed protrusion 127 is positioned to correspond to the bottom ends of the lower protrusion 122.

[0033] A limiting groove 112 is fixedly opened on the end face of the upper mold body 111. A pressure ring 113 is elastically and movably arranged in the limiting groove 112. A pressure rib 114 is provided at the middle position of the surface of the pressure ring 113. The pressure ring 113 is elastically and movably arranged inside the limiting groove 112. In this way, when the upper mold assembly 11 and the lower mold assembly 12 come into contact, they will come into contact with the pressure rib 114 on the pressure ring 113. When pressing down, the pressure ring 113 is pressed down as a whole.

[0034] An auxiliary cleaning component 2 is provided on the outside of the GMT mold assembly 1. The auxiliary cleaning component 2 cleans the surface of the GMT mold assembly 1 and the auxiliary cleaning component 2 during the production process to prevent dust and debris from affecting the product production quality. Specifically, it includes a guide rail, a drive motor, a cleaning brush, and a hydraulic rod. The whole is existing technology and will not be described in detail here.

[0035] In use, the product to be molded is placed between the upper mold assembly 11 and the lower mold assembly 12, and the two are closed. The product first contacts the pressure rib 114 on the pressure ring 113, and the pressure ring 113 pre-presses it. At the same time, the pressure protrusion 115 on the side protrusion 116 contacts the pressure groove 128 on the lower side protrusion 122 to fix the two sides of the product, and the limiting spring 126 provides a certain elastic restriction to ensure that the product will not wrinkle.
