Description

Technical Field

[0001] This application relates to the field of iron shoe manufacturing, and in particular to a pretreatment process and apparatus for iron shoe injection molding. Background Technology

[0002] Most modern iron soleplates are made of stainless steel or chrome-plated iron or aluminum. Because they are mostly metal, the soleplate's temperature gradually rises to almost the same as the steam when steam passes through it. Direct contact between the hot soleplate and fabrics like polyester or fur can deform or even melt the fabric, causing irreparable damage. Therefore, using ironing shoes regularly reduces the contact temperature between the iron and the fabric, preventing the fabric from becoming dull or damaged after ironing.

[0003] Iron shoes are manufactured by first bending a thin metal sheet into a base material that matches the shape of an iron soleplate. Figure 1 As shown, the base material of the ironing shoe is often machined with steam jet holes for steam injection, positioning protrusions for mounting with the iron, and connectors for connecting and fixing with the iron. Then, the base material of the ironing shoe needs to be selectively sprayed with a treatment agent on designated parts. Finally, the ironing shoe with the sprayed treatment agent is injection molded as a finished product for subsequent finishing and sale.

[0004] When spraying the treatment agent, it may sometimes be sprayed through the air nozzle to other places, or sometimes to areas that do not need to be sprayed. This increases the difficulty of spraying the treatment agent and reduces its efficiency, thereby slowing down the production progress of the ironing shoes. Summary of the Invention

[0005] In order to reduce the difficulty of spraying the treatment agent, improve the spraying efficiency of the treatment agent, and speed up the production progress of iron shoes, this application provides a pretreatment process and apparatus for injection molding of iron shoes.

[0006] First aspect

[0007] The technical solution for the pre-treatment process of injection molding for iron shoes provided in this application is as follows:

[0008] A pretreatment process for injection molding of iron shoes specifically includes the following steps:

[0009] Step 1: Prepare a covering device for covering the base material of the iron shoe, and prepare a spraying device for spraying the base material of the iron shoe. The spraying device is filled with a treatment agent.

[0010] Step 2: Determine the end face where the iron shoe substrate connects to the iron as the spraying area;

[0011] Step 3, placing the iron shoe substrate on the covering device, the spraying position on the iron shoe substrate is above the covering device, and the end surface of the iron shoe substrate in contact with the fabric is covered by the covering device;

[0012] Step 4, the covering device covers the air injection hole, the positioning protrusion and the connecting piece of the iron shoe;

[0013] Step 5, the spraying device sprays the spraying position of the iron shoe substrate until the spraying position on the iron shoe substrate is fully sprayed with the treatment agent;

[0014] Step 6, after the treatment agent on the iron shoe substrate is dried, the iron shoe substrate is separated from the covering device.

[0015] By adopting the above technical scheme, when spraying the iron shoe substrate, the non-sprayed position of the iron shoe substrate is shielded by the covering device, and the sprayed position is exposed, so as to avoid the non-sprayed position being sprayed with the treatment agent as much as possible. Since the air injection hole is covered, the probability of the treatment agent being sprayed to other places through the air injection hole is reduced, thereby reducing the spraying difficulty of the treatment agent as a whole, improving the spraying efficiency of the treatment agent, and speeding up the production progress of the iron shoe.

[0016] The second aspect

[0017] The iron shoe pre-injection covering device provided by the present application adopts the following technical scheme:

[0018] An iron shoe pre-injection covering device, comprising a bottom cover, an outer edge cover ring, a plug column, a cover column and a connecting shield plate;

[0019] The bottom cover is a thin plate matched with the end surface of the iron shoe substrate, the outer edge cover ring is a ring strip sleeved on the bottom cover and matched with the side wall of the iron shoe substrate, the plug column is fixed on the end surface of the bottom cover and used for plugging the air injection hole on the iron shoe substrate, the cover column is used for covering the positioning protrusion on the iron shoe substrate, and the connecting shield plate is used for covering the connecting piece on the iron shoe substrate.

[0020] By adopting the above technical scheme, when the iron shoe substrate is covered, the iron shoe substrate is first placed on the bottom cover, so that the end surface of the iron shoe substrate in contact with the fabric abuts against the bottom cover, and the outer edge cover ring covers the outer side wall of the iron shoe substrate. When the iron shoe substrate is placed on the bottom cover, the plug column is slidably inserted into the air injection hole on the iron shoe substrate to block the treatment agent from being sprayed into the air injection hole.

[0021] Furthermore, the cover column covers the positioning protrusion to cover the positioning protrusion, and finally the connecting shield plate covers the connecting piece, so as to realize the overall covering of the iron shoe substrate, reduce the spraying difficulty of the treatment agent, improve the spraying efficiency of the treatment agent, and speed up the production progress of the iron shoe.

[0022] Preferably, a cylindrical magnet is coaxially mounted at one end of the cover column, and a cladding hole is formed in the end surface of the cylindrical magnet away from the cover column for inserting the positioning protrusion on the sole material of the iron shoe.

[0023] By adopting the above technical scheme, when the cover column covers the positioning protrusion, the end of the cover column on which the cylindrical magnet is mounted covers the positioning protrusion, and at this time the positioning protrusion is inserted into the cladding hole of the cylindrical magnet. On the one hand, the connection strength of the cover column and the positioning protrusion is strengthened, and the probability of the cover column being offset in position or even falling off the positioning protrusion due to slight collision is reduced. On the other hand, the connection accuracy of the cover column and the positioning protrusion is improved through the cladding hole, and the positioning protrusion is cladded in all directions, thereby improving the cladding effect on the positioning protrusion.

[0024] Preferably, a cladding through slot is formed in the outer edge cover ring for the connecting piece on the sole material of the iron shoe to pass through, a spraying baffle is arranged on the connecting cover plate to shield the slot opening of the cladding through slot, and the spraying baffle is attached to the inner wall of the outer edge cover ring.

[0025] By adopting the above technical scheme, when the connecting cover plate clads the connecting piece, the connecting cover plate covers the connecting piece to shield the spraying direction of the treatment agent from top to bottom. However, since the cladding through slot is formed, the treatment agent may splash onto the connecting piece through the cladding through slot during spraying of the spraying part of the sole base of the iron shoe. Therefore, the slot opening of the cladding through slot is shielded by the spraying baffle to increase the cladding angle of the connecting piece and improve the cladding effect on the connecting piece.

[0026] Preferably, a connecting support is fixed to one side of the bottom cover, the connecting piece on the sole material of the iron shoe is placed on the connecting support, and the side of the connecting support away from the bottom cover is hingedly connected to the connecting cover plate.

[0027] By adopting the above technical scheme, since the connecting cover plate is hingedly connected to the connecting support, the rotation direction of the connecting cover plate is limited. When the sole material of the iron shoe is placed on the bottom cover, the connecting piece is placed on the connecting support, the connecting piece is preliminarily positioned by the connecting support supporting the connecting piece, the connecting cover plate is rotated in the direction close to the bottom cover to cover the connecting piece, so that the connecting cover plate can clad the connecting piece without aligning the connecting piece, and the spraying baffle can directly and accurately shield the cladding through slot, thereby speeding up the cladding speed of the connecting cover plate on the connecting piece.

[0028] Preferably, a disengagement assembly for pushing the sole material of the iron shoe away from the bottom cover is arranged on the bottom cover, and the disengagement assembly comprises a disengagement sliding plate, a control piece and a reset piece.

[0029] The disengaging slide plate is slidingly installed on the bottom cover along the axial direction of the inserting column, the control member is connected with the disengaging slide plate and is used to drive the disengaging slide plate to slide in the direction away from the bottom cover, and the resetting member is connected with the disengaging slide plate and is used to drive the disengaging slide plate to slide in the direction close to the bottom cover.

[0030] By adopting the above technical scheme, when the ironing shoe substrate is placed on the disengaging slide plate, after the ironing shoe substrate is sprayed, the control member is used to drive the disengaging slide plate to slide in the direction away from the bottom cover, so as to push the ironing shoe substrate to slide away from the outer cover ring, so that the ironing shoe substrate is taken away from the coating device through the outer side wall of the ironing shoe substrate in the case that the treatment agent is not dry, and meanwhile the spraying part of the ironing shoe substrate is not damaged, and the resetting member is used to drive the disengaging slide plate to slide in the direction close to the bottom cover to the original position, so as to put the next un-sprayed ironing shoe substrate. Therefore, the working efficiency of the coating device is improved.

[0031] Preferably, the control member comprises a top disengaging rotating rod, a top disengaging spring and a control slide plate.

[0032] The top disengaging rotating rod is in abutment with the end face of the disengaging slide plate opposite to the bottom cover, one end of the top disengaging rotating rod is hinged to the bottom cover along the radial direction of the inserting column, the other end of the top disengaging rotating rod is rotated in the direction close to or away from the bottom cover, the top disengaging spring is connected between the top disengaging rotating rod and the bottom cover and is used to drive the top disengaging rotating rod to rotate in the direction away from the bottom cover, and the control slide plate is in sliding abutment with the top disengaging rotating rod and is used to drive the top disengaging rotating rod to rotate in the direction close to the bottom cover.

[0033] By adopting the above technical scheme, when the control member drives the control slide plate to slide in the direction away from the bottom cover, the control slide plate slides in the direction away from the top disengaging rotating rod, at this time, the top disengaging spring is in the elongated state. In the case that the control slide plate is not in abutment, the top disengaging rotating rod is driven by the top disengaging spring to rotate in the direction away from the bottom cover, and the top disengaging rotating rod is in abutment with the disengaging slide plate in the process of rotating and pushes the disengaging slide plate to slide in the direction away from the bottom cover, so as to realize the effect of pushing the disengaging slide plate to slide in the direction away from the bottom cover.

[0034] Preferably, the control slide plate is arranged in the direction parallel to the bottom cover and is in sliding connection with the bottom cover, one end of the control slide plate is in sliding abutment with the peripheral wall of the top disengaging rotating rod and slides in the direction close to or away from the top disengaging rotating rod, a control sliding groove is formed in the peripheral wall of the bottom cover and is used for the sliding of the control slide plate, and the other end of the control slide plate away from the top disengaging rotating rod slides through the control sliding groove.

[0035] By adopting the above technical scheme, the control slide plate can slide in the arrangement direction of the control sliding groove. When the control slide plate slides in the direction close to the side wall of the bottom cover, the control slide plate is away from the top disengaging rotating rod, and when the control slide plate slides in the direction away from the side wall of the bottom cover, the control slide plate is close to the top disengaging rotating rod and pushes the top disengaging rotating rod to rotate in the direction close to the bottom cover.

[0036] Preferably, the control slide is fixed with a manual slide bar at one end away from the top-off rotary lever, and the manual slide bar is an arc-shaped long strip in contact with the outer cover ring.

[0037] By using the above technical scheme, the sliding direction of the control slide is controlled by the manual slide bar, and the operation difficulty of the disengagement assembly is reduced.

[0038] Preferably, the reset member includes a first reset spring and a second reset spring.

[0039] The first reset spring is arranged along the axis direction of the insertion column, and the two ends of the first reset spring are fixedly connected with the bottom cover and the disengagement slide respectively.

[0040] The second reset spring is arranged along the sliding direction of the control slide, and the two ends of the second reset spring are fixedly connected with the bottom cover and the control slide respectively.

[0041] By using the above technical scheme, when the top-off rotary lever drives the disengagement slide to slide away from the bottom cover, the first reset spring is elongated due to external force. When the top-off rotary lever rotates towards the bottom cover, the first reset spring is retracted to drive the disengagement slide to slide towards the bottom cover for resetting.

[0042] When the manual slide bar is pulled to make the control slide slide towards the side wall of the bottom cover, the second reset spring is contracted due to external force. When the manual slide bar is released, the second reset spring is stretched to drive the control slide to slide towards the top-off rotary lever for resetting.

[0043] In summary, the present application has at least one of the following beneficial technical effects:

[0044] 1. The uncoated part of the iron shoe base material is shielded by the covering device, and the coated part is exposed, so as to avoid the uncoated part being sprayed with the treatment agent as much as possible, thereby reducing the spraying difficulty of the treatment agent, improving the spraying efficiency of the treatment agent, and speeding up the production progress of the iron shoe;

[0045] 2. When the iron shoe base material is covered, the end surface of the iron shoe base material in contact with the fabric abuts against the bottom cover, the outer cover ring covers the outer side wall of the iron shoe base material, the insertion column slides into the air injection hole on the iron shoe base material, the cover column covers the positioning protrusion, and the connecting shield covers the connecting member, so as to realize the overall covering of the iron shoe base material, thereby reducing the spraying difficulty of the treatment agent, improving the spraying efficiency of the treatment agent, and speeding up the production progress of the iron shoe;

[0046] 3. The control member drives the disengaging slide to slide in the direction away from the bottom cover, thereby pushing the sole substrate of the iron shoe to slide out of the outer cover ring, so as to facilitate the sole substrate of the iron shoe to be taken out of the coating device through the outer side wall of the sole substrate of the iron shoe without damaging the spraying part of the sole substrate of the iron shoe when the treatment agent is not dry.

DETAILED DESCRIPTION

[0054] The following will be described in detail with reference to the accompanying drawings. Figures 1-6 The present application will be further described in detail.

[0055] The embodiment of the present application discloses an iron shoe pre-injection treatment process. Referring to Figure 2 and Figure 3 , specifically comprising the following steps:

[0056] Step 1, preparing the coating device 4 for coating the sole substrate 1 of the iron shoe, preparing the spraying device for spraying the sole substrate 1 of the iron shoe, and filling the spraying device with treatment agent;

[0057] Step 2, determine the end surface of the iron shoe base material 1 connected with the iron as the spraying position 12;

[0058] Step 3, place the iron shoe base material 1 on the covering device 4, the spraying position 12 on the iron shoe base material 1 is above the covering device 4, and the end surface of the iron shoe base material 1 in contact with the fabric is covered by the covering device 4;

[0059] Step 4, the covering device 4 covers the air jet hole 11, the positioning protrusion 2 and the connecting piece 3 of the iron shoe;

[0060] Step 5, the spraying device sprays the spraying position 12 of the iron shoe base material 1 until the spraying position 12 on the iron shoe base material 1 is fully sprayed with the treatment agent;

[0061] Step 6, after the treatment agent on the iron shoe base material 1 is dried, the iron shoe base material 1 is separated from the covering device 4.

[0062] When spraying the iron shoe base material 1, the non-sprayed position of the iron shoe base material 1 is shielded by the covering device 4, and the sprayed position is exposed, which can avoid the non-sprayed position being sprayed with the treatment agent as much as possible, and can reduce the probability of the treatment agent being sprayed to other places through the air jet hole 11, thereby reducing the spraying difficulty of the treatment agent as a whole, improving the spraying efficiency of the treatment agent and speeding up the production progress of the iron shoe.

[0063] The embodiment of the application further discloses a covering device before iron shoe injection molding. Referring to Figure 2 , the covering device 4 comprises a bottom cover 41, an outer edge cover ring 42, a plug column 43, a cover column 44, a connecting shield 45 and a separation assembly 5.

[0064] As shown in Figure 2 and Figure 3 , the bottom cover 41 is a thin plate matched with the end surface of the iron shoe base material 1. The outer edge cover ring 42 is sleeved on the peripheral wall of the bottom cover 41 and is a ring strip matched with the side wall of the iron shoe base material 1. The plug column 43 is fixed on the end surface of the bottom cover 41, and the axis of the plug column 43 is vertically arranged on the end surface of the bottom cover 41. When the iron shoe base material 1 is placed on the covering device 4, the non-sprayed end surface of the iron shoe base material 1 abuts against the end surface of the bottom cover 41, the peripheral wall of the iron shoe base material 1 abuts against the inner peripheral wall of the outer edge cover ring 42, and the plug column 43 is slidably inserted through the air jet hole 11.

[0065] In addition, as shown in Figure 4As shown, one end of the cover column 44 is coaxially provided with a columnar magnet 46 which is magnetically connected with the positioning protrusion 2. When the cover column 44 covers the positioning protrusion 2, the end surface of the columnar magnet 46 away from the cover column 44 is magnetically connected with the positioning protrusion 2, thereby enhancing the connection strength between the cover column 44 and the positioning protrusion 2. The columnar magnet 46 is further provided with a covering hole 461 for the positioning protrusion 2 to insert, thereby improving the connection precision between the cover column 44 and the positioning protrusion 2 and the covering effect on the positioning protrusion 2.

[0066] In addition, as shown in Figure 2 and Figure 3 the outer cover ring 42 is provided with a covering through slot 421 for the connecting member 3 on the ironing shoe base material 1 to pass through, and the bottom cover 41 is fixed with a connecting support 48 for bearing the connecting member 3. When the ironing shoe base material 1 is placed on the bottom cover 41, the connecting member 3 passes through the covering through slot 421 and is placed on the connecting support 48. One end of the connecting cover plate 45 is hingedly connected with the side of the connecting support 48 away from the bottom cover 41, so that the connecting cover plate 45 can be rotated in the direction approaching or away from the bottom cover 41, so as to cover the connecting member 3.

[0067] The connecting cover plate 45 is further fixed with a spraying baffle 47 away from the hingedly connected end with the connecting support 48. When the connecting cover plate 45 covers the connecting member 3, the spraying baffle 47 can slide against the inner circumferential wall of the outer cover ring 42, thereby shielding the slot of the covering through slot 421 through the spraying baffle 47, so as to reduce the probability of the processing agent splashing onto the connecting member 3 when sprayed.

[0068] In addition, as shown in Figure 5 and Figure 6 the disengaging assembly 5 comprises a disengaging slide plate 51, a control member 52 and a reset member 53.

[0069] The disengaging slide plate 51 is slidingly installed on the bottom cover 41 along the axis direction of the insertion column 43. The control member 52 is installed on the bottom cover 41 and connected with the disengaging slide plate 51, and the disengaging slide plate 51 can be slidingly driven by the control member 52 in the direction away from the bottom cover 41. The reset member 53 is installed on the bottom cover 41 and connected with the disengaging slide plate 51, and the disengaging slide plate 51 can be slidingly driven by the reset member 53 in the direction approaching the bottom cover 41.

[0070] When the iron shoe substrate 1 is placed on the bottom cover 41, the iron shoe substrate 1 abuts against the disengaging slide plate 51. When the iron shoe substrate 1 is finished with the treatment agent spraying, the disengaging slide plate 51 is driven by the control member 52 to slide the iron shoe substrate 1 away from the bottom cover 41, so that the iron shoe substrate 1 can be taken away from the coating device 4 without damaging the sprayed part 12 of the iron shoe substrate 1 when the treatment agent is not dry. The disengaging slide plate 51 is driven by the reset member 53 to slide to the original position close to the bottom cover 41, so that the next iron shoe substrate 1 which is not sprayed can be placed in. Thus, the working efficiency of the coating device 4 is improved.

[0071] With reference to Figure 5 and Figure 6 , the control member 52 comprises a top disengaging rotating rod 521, a top disengaging spring 522 and a control slide plate 523.

[0072] The end face of the bottom cover 41 opposite to the iron shoe substrate 1 is provided with a top disengaging rotating groove 411, and the top disengaging rotating rod 521 is located in the top disengaging rotating groove 411 and abuts against the end face of the disengaging slide plate 51. One end of the top disengaging rotating rod 521 is hinged to the bottom cover 41 along the radial direction of the insertion column 43, so that the other end of the top disengaging rotating rod 521 can rotate in the direction close to or away from the bottom cover 41. The top disengaging spring 522 is connected between the top disengaging rotating rod 521 and the bottom cover 41 and is used to drive the top disengaging rotating rod 521 to rotate in the direction away from the bottom cover 41, so that the top disengaging rotating rod 521 can push the disengaging slide plate 51 to slide in the direction away from the bottom cover 41. The control slide plate 523 is in sliding abutment with the top disengaging rotating rod 521 and is used to drive the top disengaging rotating rod 521 to rotate in the direction close to the bottom cover 41.

[0073] As shown in Figure 5 and Figure 6 , the control slide plate 523 is arranged in the direction parallel to the bottom cover 41 and is in sliding connection with the bottom cover 41. The peripheral wall of the bottom cover 41 is provided with a control sliding groove 413 for the sliding of the control slide plate 523, and the bottom cover 41 is provided with a connecting sliding groove 412 for guiding the sliding direction of the control slide plate 523. The connecting sliding groove 412 communicates the control sliding groove 413 and the top disengaging rotating groove 411. One end of the control slide plate 523 is in sliding abutment with the peripheral wall of the top disengaging rotating rod 521 and slides in the connecting sliding groove 412 in the direction close to or away from the top disengaging rotating rod 521.

[0074] The other end of the control slide plate 523 away from the top disengaging rotating rod 521 slides through the control sliding groove 413 and is connected with a manual sliding bar 524. The manual sliding bar 524 is an arc-shaped long strip which is in abutment with the outer cover ring 42. The manual sliding bar 524 can be used to pull the control slide plate 523, so as to control the sliding direction of the control slide plate 523 and reduce the operation difficulty of the disengaging assembly 5.

[0075] With reference to Figure 4 and Figure 5The reset member 53 comprises a first reset spring 531 and a second reset spring 532.

[0076] The first reset spring 531 is arranged along the axial direction of the insertion column 43, and the two ends of the first reset spring 531 are fixedly connected with the bottom cover 41 and the separation slide plate 51 respectively. When the top separation rotating rod 521 drives the separation slide plate 51 to slide away from the bottom cover 41, the first reset spring 531 is elongated due to external force. When the top separation rotating rod 521 rotates towards the bottom cover 41, the first reset spring 531 is retracted to drive the separation slide plate 51 to slide towards the bottom cover 41.

[0077] The second reset spring 532 is arranged along the sliding direction of the control slide plate 523 and located in the connecting sliding groove 412, and the two ends of the second reset spring 532 are fixedly connected with the groove wall of the connecting sliding groove 412 and the control slide plate 523 respectively. When the manual slide bar 524 is pulled to make the control slide plate 523 slide towards the side wall of the bottom cover 41, the second reset spring 532 is contracted due to external force. When the manual slide bar 524 is released, the second reset spring 532 is stretched to drive the control slide plate 523 to slide towards the top separation rotating rod 521.

[0078] The implementation principle of the iron shoe injection molding pre-coating device is as follows: when the iron shoe base material 1 is coated, first, the iron shoe base material 1 is placed on the bottom cover 41, the insertion column 43 is slidably inserted into the air injection hole 11 on the iron shoe base material 1, second, the cover column 44 is covered on the positioning protrusion 2, third, the connecting cover plate 45 is rotated and covered on the connecting piece 3, the injection baffle 47 shields the coating through groove 421, then the iron shoe base material 1 is sprayed, after spraying, the manual slide bar 524 is pulled, the manual slide bar 524 drives the control slide plate 523 to move away from the top separation rotating rod 521, the top separation rotating rod 521 rotates away from the bottom cover 41, thereby pushing the separation slide plate 51 to drive the iron shoe base material 1 to slide away from the bottom cover 41, finally, the iron shoe base material 1 is taken away from the coating device 4. Finally, the spraying difficulty of the treatment agent is reduced, the spraying efficiency of the treatment agent is improved, and the production progress of the iron shoe is accelerated.
