Description

Technical Field

[0001] The invention relates to the technical field of hot pressing molding, and in particular to a molding die for processing a swimming goggle protective pad and a molding method thereof. Background Art

[0002] The hot press is a device that heats two pre-fluxed tinned parts to a temperature sufficient to melt and flow the solder, and after solidification, forms a permanent electrical and mechanical connection between the parts and the solder. The heating rate can be selected according to different products. The titanium alloy pressure head ensures uniform temperature, fast heating and long service life. The pressure head is specially designed with horizontal adjustment to ensure that the components are evenly pressed. The temperature is digitally controlled, clear and precise. A digital pressure gauge is available to preset the pressure range.

[0003] The staff manually places each piece of TPE material on the hot pressing plane, and uses hot pressing to make it fit the shape of the mold. This is achieved through negative pressure vacuum forming or positive pressure blow molding, so that the material forms the desired shape of the goggles pad in the mold. After the plastic is completely solidified, the upper and lower modules of the mold are separated, and the molded goggles pad is ejected from the mold through the coordinated action of the cylinder and telescopic rod.

[0004] When the above-mentioned molding mold for processing goggle pads is in use, the staff manually places the cut TPE on the hot pressing platform. TPE has high elasticity and memory effect. Since TPE will be pulled when cutting, the material gradually rebounds to its original shape while being placed waiting for processing, resulting in curling of the edge of the TPE. The two layers of the TPE curled edge cannot be completely melted after hot pressing, resulting in cracking and stratification of the processed goggle pads. The cracking or stratification of the pads will cause the goggles to be in loose contact with the face, and the goggles cannot be completely sealed, causing water to enter the goggles, affecting the line of sight and swimming experience. In addition, the staff's hands are in contact with TPE for a long time, resulting in a slight sticky feeling on the palms, which is easy to adhere to impurities on the hands. The impurities carried will be left on the TPE or the hot pressing platform. Impurities will cause bubbles, dents or scratches on the TPE surface after hot pressing, affecting the appearance and quality of the product. The defects caused by impurities will lead to a higher scrap rate, thereby increasing production costs. Summary of the invention

[0016] As a preferred solution of the molding die for processing goggle pads described in the present invention, a rounded groove is provided on one side of the clamping plate one, flip slide grooves are provided on both sides of the clamping plate one, the clamping plate one is slidably connected to a flip column, a flip slide plate is connected to the flip column, a torsion spring shaft is connected to a portion of the flip slide plate away from the flip column, a half gear is connected to a portion of the flip column away from the flip slide plate, a tooth block is connected to a portion of the slide rail frame, and a stop block is connected to one end of the slide rail frame away from the tooth block.

[0017] A molding die for processing a swimming goggle pad includes the following molding method:

[0018] S1, clamping TPE for loading, driving the driving disc to rotate clockwise through the output end of the motor, so that the meshing belt slides along the groove limit frame, driving the limit slide on the belt to slide to the right along the slide housing, and sliding the two T-shaped slides in the limit slide respectively drive rollers 1 and 2 to slide along the limit slide groove. When rollers 1 and 2 gradually rise along the slope of the limit slide groove, the T-shaped slide will slide up and down along the slide groove opened in the limit slide for adaptive adjustment, driving one end of the transmission rod 1 and the transmission rod 2 to rotate and open, so that the clamping plate 1 and the clamping plate 2 connected at the other end are rotated to clamp the TPE material strips delivered from the discharge port under the limit of the limit slide column, and the clamping plate 1 and the clamping plate 2 continue to slide to the right along the slide rail frame while the discharge port continues to deliver the TPE material strips, and the TPE material strips are suspended above the hot press box;

[0019] S2, press to relieve the pulling force of the tool on TPE. When the limit slide drives the second roller to slide along the limit slide groove on the slide rail, it will contact the limit block set at the right end of the limit slide groove. When the second roller continues to slide, it will push the limit block to drive the elastic storage chamber to slide into the placement groove on the slope of the limit slide groove. When the elastic storage chamber slides into the placement groove, it will drive the limit slide plate on the other side to retract and slide into the slide rail frame. When the limit slide plate moves away from the lower surface of the sliding inclined block, the compressed pressing spring sheet pushes the sliding inclined block under the reaction force. The block slides downward along the lifting slide groove opened at one end of the limit plate, and drives the pressing plate 1 and the rack 1 to slide downward at the same time through the L-shaped fixed block on one side. When the rack 1 slides downward, it drives the driving gear on one side to rotate and pushes the rack 2 on the other side upward, driving the pressing plate 2 at one end of the rack 2 to slide upward, and the TPE material strip near the discharge port is pressed and limited by the pressing plate 1 and the pressing plate 2 at the same time, and the cutting tool is driven to move down along the cutting groove through the cylinder output end on the upper surface of the pressing plate 1 to cut the TPE material strip;

[0020] S3. Lay TPE on the processing surface. When roller one and roller two slide along the limiting slide groove to the inclined downhill at the right end, the block at one place of the slide rail frame will contact the end of the flip column. When clamping plate one and clamping plate two continue to slide and open to the right end, the flip slide plates on both sides of the flip column are pushed to slide along the flip slide grooves on both sides of clamping plate one into the circular groove. The flip slide plate is pushed by the torsion spring shaft to drive the torsion spring shaft to rotate counterclockwise along the circular groove. The flip column rotates and pushes the TPE material strip placed on the upper surface of clamping plate two to the upper surface of the hot press box through clamping plate two. While the flip column rotates counterclockwise, it will slide along the upper surface of the TPE material strip to flatten the curled TPE material strip. The output end of the motor drives the driving disc to rotate counterclockwise, and the belt drives the clamping plate one and the flip column to slide along the upper surface of the TPE material strip. Roller two slides along the limiting slide groove When it reaches the rounded corner of one of the limit blocks, the limit block is pushed to slide upward into the elastic storage chamber to allow the second roller to pass, and the TPE material strip is gradually attached to the hot press box. The TPE material strip will fall off from the pressing plate 1 and the pressing plate 2 under the action of inertia. When the vertical half gear of the flip column is upward, the sliding will contact and gradually engage with the tooth block, driving the vertical flip slide plate in the circular groove to rotate to the horizontal. The rotating horizontal flip column will be engaged with the bevel groove between the pressing plate 1 and the pressing plate 2, and the half gear and the tooth block lose engagement, pushing the horizontal flip column and the flip slide plate to slide back along the flip slide groove. When the closed clamping plate 1 and the clamping plate 2 slide to the slope at the left end, the pressing plate 1 and the pressing plate 2 with the bevel groove are gradually opened through the rounded corner groove and the flip column, so that the sliding bevel block slides upward along the lifting slide groove to extrude the pressing spring piece, and the sliding bevel block pushes the limit slide plate to be engaged with the upper surface of the limit slide plate.

[0021] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0022] 1. The T-shaped slide plate slides up and down along the slide groove opened in the limit slide for adaptive adjustment, driving one end of the transmission rod 1 and the transmission rod 2 to rotate and open, so that the clamping plate 1 and the clamping plate 2 connected at the other end can clamp and load the TPE material strips delivered from the discharge port under the limit of the limit slide column. Multiple TPE strips can be clamped and loaded at the same time, reducing the time for manual operation of placing them one by one, significantly improving the production speed, reducing the waiting time of hot pressing equipment, improving production efficiency, ensuring the cleanliness of the material, and avoiding manual operation. Impurities such as grease and dust on the hands are brought into the material, thereby improving the quality of the final product.

[0023] 2. Use the pressing plate 1 and the pressing plate 2 to press and limit the TPE strip near the outlet at the same time. Use the cylinder output end on the upper surface of the pressing plate 1 to drive the cutting tool to move down along the cutting groove to cut the TPE strip. Pressing up and down at the same time can ensure that the material is evenly stressed during the cutting process, avoid deformation of the material due to uneven pressure, and reduce damage to TPE during the cutting process. Pressing up and down at the same time can evenly distribute the cutting force, effectively prevent the TPE edge from curling or warping due to uneven force, and maintain the integrity of the material.

[0024] 3. The turning column rotates to push the TPE strip placed on the upper surface of the clamping plate 2 to the upper surface of the hot press box through the clamping plate 2. The turning column rotates counterclockwise and slides along the upper surface of the TPE strip to flatten the curled TPE strip. The TPE will be flattened while the material is automatically unloaded to avoid the curling of the TPE, which helps to ensure the flatness of the TPE and avoid product quality problems caused by wrinkles or bending of the material.

[0025] 4. The output end of the motor drives the driving disc to rotate counterclockwise, and the belt drives the clamping plate and the flip column to slide along the upper surface of the TPE material strip. By pressing, the TPE is made to fit the hot pressing plane more closely, which can ensure that the material is heated evenly during the hot pressing process, and there is no air gap between the TPE and the hot pressing plane, thereby improving the fit and bonding effect and maintaining the shape and dimensional accuracy of the product.

[0026] 5. The sliding will contact and gradually mesh with the tooth block, driving the vertical flip slide in the circular groove to rotate to the horizontal. The rotating horizontal flip column will engage with the bevel groove between the pressing plate 1 and the pressing plate 2, and the half gear and the tooth block will lose meshing, pushing the horizontal flip column and the flip slide to slide back along the flip chute. By resetting multiple functions synchronously, the overall preparation time can be reduced, making the production line or workflow more efficient, ensuring that all relevant components and functions are in the correct state, avoiding delays or errors caused by the failure to reset some functions, and preparing for the second loading process.
