TECHNICAL FIELD
[0001] The application relates to the technical field of shoe sole processing, in particular to a demolding tool for shoe sole processing. BACKGROUND
[0002] A shoe sole is an important component of a shoe, and is divided into PU soles, polyurethane soles, rubber soles and the like according to different materials, wherein the rubber soles are generally injection molded in a mold, and need to be taken out of the mold after injection molding, so that a demolding tool needs to be used to complete the demolding process, and the demolding tool is generally a clamp.
[0003] However, the ordinary clamp in the market is difficult to meet the use requirement when being applied to demolding of a shoe sole of a high-heeled shoe, because the shoe sole is combined with the mold relatively deeply, the explosive force required for dragging the mold to the outside is relatively large during demolding, the shoe sole is easily damaged due to insufficient explosive force, or the clamp slides relative to the shoe sole, and thus the use requirement needs to be improved. CONTENT OF THE UTILITY MODEL
[0004] In order to meet the requirement of taking out the shoe sole of a high-heeled shoe from a mold, the application provides a demolding tool for shoe sole processing.
[0005] The application provides a demolding tool for shoe sole processing, which adopts the following technical scheme:
[0006] The demolding tool for shoe sole processing comprises a clamp base, a first connecting rod fixedly arranged on the clamp base, first clamp arms and a first clamp mouth arranged on two sides of the first connecting rod, a second connecting rod rotatably arranged on the clamp base, second clamp arms and a second clamp mouth arranged on two sides of the second connecting rod, a clamping groove for clamping the shoe sole is formed between the first clamp mouth and the second clamp mouth, the first clamp arms are perpendicular to the first connecting rod, the second clamp arms are perpendicular to the second connecting rod, and the first clamp mouth and the second clamp mouth move towards each other or move away from each other when the first clamp arms and the second clamp arms rotate relative to each other.
[0007] By adopting the technical scheme, when the shoe sole of the high-heeled shoe is demolded, the demolding tool only needs to be moved to the shoe sole formed in the mold, the shoe sole is caused to extend into the clamping groove, the end of the first clamping arm away from the second clamping arm is caused to abut against the mold, then the second clamping arm is pulled upward, the first clamping arm and the second clamping arm are caused to rotate relative to each other, and then the first jaw and the second jaw are caused to move towards each other and clamp the shoe sole, so that the shoe sole can be pulled out of the mold while being clamped. Compared with the demolding mode using the ordinary clamp, the force point is the part of the first clamping arm in contact with the mold, and the moment of force is changed from the length of the handle of the ordinary clamp to the total length of the first clamping arm and the second clamping arm, so that in the case of the same explosive force, the force required by the operator is smaller, and manpower is saved. Moreover, the force acting on the shoe sole during demolding is large, the first jaw and the second jaw are not easy to slide relative to the shoe sole and damage the shoe sole, so that the shoe sole can be safely demolded from the mold, and the product quality of the shoe sole is ensured.
[0008] Optionally, the first jaw and the second jaw each include two oppositely arranged jaw teeth, and a clamping groove for clamping the shoe sole is formed between the two jaw teeth.
[0009] By adopting the technical scheme, when the shoe sole is clamped by the first jaw and the second jaw, the shoe sole is not only located in the clamping groove, but also located in the clamping groove. The contact area between the first jaw, the second jaw and the shoe sole is large, and the clamping effect is good, which helps the shoe sole to be demolded from the mold.
[0010] Optionally, the opposite side walls of the two jaw teeth in the first jaw and the opposite side walls of the two jaw teeth in the second jaw are each provided with an anti-skid groove.
[0011] By adopting the technical scheme, the anti-skid groove can increase the friction between the jaw teeth and the shoe sole, so that the shoe sole is more easily taken out of the mold by the jaw teeth.
[0012] Optionally, the length of the first connecting rod is greater than the length of the second connecting rod, and when the shoe sole is clamped by the first jaw and the second jaw, the second clamping arm is located on the side of the first clamping arm close to the jaw seat.
[0013] By adopting the technical scheme, when demolding, the first clamping arm and the second clamping arm are staggered with each other, and are not easy to affect the clamping effect of the first jaw and the second jaw on the shoe sole due to the abutment of the ends of the first clamping arm and the second clamping arm close to each other.
[0014] Optionally, the first clamping arm includes an elongated part, the second clamping arm is provided with a limiting piece for positioning the elongated part, and when the shoe sole is clamped by the first jaw and the second jaw, the elongated part is limited in the limiting piece.
[0015] By adopting the technical scheme, when the sole is demolded, the second clamping arm needs to be pulled upward, at this time, the lengthening part abuts against the second clamping arm, the limiting piece can hinder the lengthening part from deviating along the circumference of the second clamping arm, and the stability of the first clamping arm is improved, and the clamping effect of the first jaw on the second jaw is ensured.
[0016] Optionally, the limiting piece comprises two limiting bolts fixed on the second clamping arm, and a limiting groove for accommodating the lengthening part is formed between the two limiting bolts.
[0017] By adopting the technical scheme, the two limiting bolts can hinder the lengthening part from deviating along the circumference of the second clamping arm, so that the first jaw and the second jaw can more stably clamp the sole, and the demolding effect is more stable. In addition, the bolt as a limiting piece has the effects of being easy to obtain and low in cost.
[0018] Optionally, a protective sleeve is detachably arranged on the side of the first clamping arm away from the lengthening part, and the protective sleeve can elastically deform when being pressed.
[0019] By adopting the technical scheme, when demolding, one end of the protective sleeve abuts between the first clamping arm and the mold, which helps to increase the contact area and friction force of the first clamping arm and the mold, so that the first clamping arm is not easy to slide off the mold, and the first clamping arm and the second clamping arm are more stable during rotation.
[0020] Optionally, a connecting groove for allowing one end of the first clamping arm to extend into is formed in the protective sleeve, a fastening bolt is penetratingly arranged between opposite groove walls of the connecting groove, a gap hole for allowing the fastening bolt to rotatingly penetrate is formed in the first clamping arm, and a fastening nut is threadedly connected to the fastening bolt.
[0021] By adopting the technical scheme, when the protective sleeve is worn, the fastening nut can be loosened first, and then the protective sleeve is rotated about the fastening bolt, so that one end of the protective sleeve which is not worn can abut between the first clamping arm and the mold, and the protective sleeve can continue to be used. When the protective sleeve is seriously worn, the fastening bolt can be directly removed to replace a new protective sleeve. Compared with replacing the entire demolding tool, only the protective sleeve needs to be replaced, which is simple in operation and saves resources.
[0022] Optionally, a rubber sleeve is arranged on the circumferential side wall of the second clamping arm away from the first clamping arm.
[0023] By adopting the technical scheme, when the second clamping arm is pulled upward by hand, the rubber sleeve can increase the friction force between the hand and the second clamping arm, so that the hand and the second clamping arm are not easy to slide relative to each other, and the risk of accidental injury is reduced. In addition, the heat generated during the injection molding of the sole is high, and the heat is easily transmitted to the hands of the operator through the demolding tool, which causes the hands to be scalded. The rubber sleeve has the functions of heat insulation and hand protection.
[0024] In summary, the present application includes at least one of the following beneficial technical effects:
[0025] 1. The demolding tool of the present application, when in use, the first clamping arm abuts on the mold, and the shoe sole held by the first and second pincers can be taken out of the mold by lifting the second clamping arm, the demolding torque is large and the effort is less, which meets the demolding needs of the shoe sole of high-heeled shoes;
[0026] 2. The first and second pincers each include two pincer teeth arranged oppositely, so that the clamping force of the first and second pincers on the shoe sole is large, and the demolding effect is good;
[0027] 3. The second clamping arm is provided with a limiting piece for positioning the elongated part, the limiting piece can hinder the elongated part from shifting along the circumference of the second clamping arm, so that the first and second pincers can more stably hold the shoe sole, and the clamping effect is good.

DETAILED DESCRIPTION
[0034] The following will be described in detail in combination with the accompanying Figures 1-4 The present application will be further described in detail.
[0035] The present application discloses a demolding tool for shoe sole processing.
[0036] Embodiment 1
[0037] Reference Figure 1The demolding tool for processing shoe sole comprises a jaw seat 5, a first connecting rod 3 fixedly arranged on the jaw seat 5, a first clamping arm 1 and a first jaw 6 arranged on two sides of the first connecting rod 3, a second connecting rod 4 rotatably arranged on the jaw seat 5, a second clamping arm 2 and a second jaw 7 arranged on two sides of the second connecting rod 4, wherein the first clamping arm 1 is fixedly connected to the first connecting rod 3, the first jaw 6 is fixedly connected to the jaw seat 5, the second clamping arm 2 is fixedly connected to the second connecting rod 4, and the second jaw 7 is rotatably connected to the jaw seat 5, and a clamping groove 8 for clamping the shoe sole is formed between the first jaw 6 and the second jaw 7.
[0038] With reference to Figure 1 , an angle is formed between the first clamping arm 1 and the first connecting rod 3 and between the second clamping arm 2 and the second connecting rod 4, and in the embodiment, the first clamping arm 1 is perpendicular to the first connecting rod 3 and the second clamping arm 2 is perpendicular to the second connecting rod 4, and in other cases, other angles can be set according to customer requirements or different use scenarios. When the first clamping arm 1 and the second clamping arm 2 rotate relative to each other, the first jaw 6 and the second jaw 7 move towards or away from each other. By rotating the first clamping arm 1 and the second clamping arm 2 relative to each other, the first jaw 6 and the second jaw 7 can move towards each other and clamp the shoe sole, which is convenient to operate.
[0039] With reference to Figure 2 , the first clamping arm 1 comprises a main body part 14 and an extension part 11 which are integrally formed, and the extension part 11 is located on one side of the main body part 14 close to the second clamping arm 2, and the second clamping arm 2 is fixedly provided with a limiting piece 21 for positioning the extension part 11, and in the embodiment, the limiting piece 21 is preferably two limiting bolts 211 fixedly arranged on the second clamping arm 2, and in other cases, different materials can be selected according to customer requirements. The two limiting bolts 211 form a limiting groove 212 for accommodating the extension part 11, and when the first jaw 6 and the second jaw 7 clamp the shoe sole, the extension part 11 is limited in the limiting groove 212, and the limiting piece 21 can prevent the extension part 11 from being offset along the circumference of the second clamping arm 2, so that the first jaw 6 and the second jaw 7 can more stably clamp the shoe sole, and the demolding effect is good.
[0040] With reference to Figure 1 , the length of the first connecting rod 3 is greater than the length of the second connecting rod 4, and when the first jaw 6 and the second jaw 7 clamp the shoe sole, the second clamping arm 2 is located on one side of the extension part 11 close to the jaw seat 5, so that the first clamping arm 1 and the second clamping arm 2 can be mutually offset after being rotated in place during demolding.
[0041] With reference to Figure 2In order to increase the clamping force of the first jaw 6 and the second jaw 7 on the sole, the first jaw 6 and the second jaw 7 each include two oppositely arranged jaw teeth 61, and a clamping groove 62 for clamping the sole is formed between the two jaw teeth 61 in the first jaw 6 and the two jaw teeth 61 in the second jaw 7. The opposite side walls of the two jaw teeth 61 in the first jaw 6 and the opposite side walls of the two jaw teeth 61 in the second jaw 7 are each provided with an anti-skid groove 63. The anti-skid groove 63 can increase the friction between the jaw teeth 61 and the sole, so that the sole is more easily pulled out of the mold when the second clamping arm 2 is pulled upward. In this embodiment, the anti-skid groove 63 is not only provided on the opposite side walls of the two jaw teeth 61 in the first jaw 6 and the opposite side walls of the two jaw teeth 61 in the second jaw 7, but also provided on the opposite two side walls of the first jaw 6 and the second jaw 7, so as to further increase the friction.
[0042] The implementation principle of the demolding tool for processing the sole in the embodiment of the present application is as follows: when demolding the sole of the high-heeled shoe, one end of the first clamping arm 1 is first abutted against the mold, and then the first jaw 6 and the second jaw 7 and the jaw teeth 61 are clamped on the sole, and then the second clamping arm 2 is pulled upward, so that the sole is pulled out of the mold, thereby saving manpower and being simple to operate.
[0043] Embodiment 2
[0044] With reference to Figure 3 and Figure 4 , the difference between this embodiment and embodiment 1 is that the first clamping arm 1 further includes a support portion 12 fixed to the main body portion 14 away from the lengthened portion 11, and a protective sleeve 9 is detachably arranged on the support portion 12. The material of the protective sleeve 9 is preferably rubber and can elastically deform when subjected to pressure. A connecting groove 91 for allowing the support portion 12 to extend into is formed in the protective sleeve 9, and a fastening bolt 92 is threadedly connected between the opposite groove walls of the connecting groove 91. The support portion 12 is provided with a clearance hole 13 for allowing the fastening bolt 92 to threadedly pass through. A fastening nut 93 is threadedly connected to the fastening bolt 92. During demolding, the protective sleeve 9 is abutted between the mold and the first clamping arm 1, thereby reducing the risk of wear of the first clamping arm 1. When the protective sleeve 9 is worn, the fastening nut 93 can be loosened to rotate the protective sleeve 9, or the fastening bolt 92 can be directly removed to replace a new protective sleeve 9. Compared with replacing the entire demolding tool, resources are saved and the operation is convenient.
[0045] With reference to Figure 3 , a rubber sleeve 10 is fixed to the circumferential side wall of the second clamping arm 2 away from the first clamping arm 1. By fixing the rubber sleeve 10 at the hand holding position of the second clamping arm 2, the heat emitted by the sole during the injection molding process can be blocked from being transmitted to the hands of the operator, thereby reducing the risk of burns. When the second clamping arm 2 is pulled upward, the rubber sleeve 10 makes the second clamping arm 2 not easy to slip, so that the demolding process is safer and the demolding effect is more stable.
[0046] The implementation principle of the demolding tool for processing a shoe sole in an embodiment of the present application is as follows: during demolding, the first clamping arm 1 is abutted on the mold through the protective sleeve 9, compared with the first clamping arm 1 directly abutting on the mold, the direct loss to the demolding tool itself is reduced; the rubber sleeve 10 can increase the friction force between the hand and the second clamping arm 2, so that the demolding process is more stable.
[0047] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so: all equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
