Description

Technical Field

[0001] This utility model relates to the field of polymer molding and processing technology, and in particular to a fixing device for mold components. Background Technology

[0002] In shoe mold making technology, the shoe last mold, which is used to cover pre-made shoes or to mold the shoe body, is fixed by appropriate fixing means when combined with other mold pieces to ensure the relative position between the shoe body and the sole. This is a known technical content.

[0003] Regarding known techniques for fixing shoe last molds, two fixing pins are typically used at at least two different locations on the shoe last mold to achieve a fixing effect. The different fixing pins disclosed in the known techniques are driven by different drive components such as fluid pressure cylinders. As a result, the overall structure of the mold becomes more complex due to the need to configure different drive components. This also leads to the limitation that it is difficult to configure two shoe last molds in the same mold composition, resulting in low production efficiency. Utility Model Content

[0004] This utility model provides a fixing device for mold components. This device can provide fixing force to the mold components used to form the mold in two different directions by external force provided by a single power source, so that the mold components are stably connected to each other and the production efficiency is improved.

[0005] The above-mentioned objective of the utility model is achieved through the following technical solution:

[0006] A fixing device for a mold component, comprising:

[0007] First mold component;

[0008] A second mold component can move between a mating position adjacent to the first mold component and a separating position away from the first mold component. When in the mating position, a first surface of the first mold component and a second surface of the second mold component face each other, and at the same time, a third surface of the first mold component and a fourth surface of the second mold component also face each other.

[0009] An actuation unit includes a first transmission component and a second transmission component. It can transmit an external force to the second transmission component via the first transmission component and change the positions of the first transmission component and the second transmission component at the same time. When the first transmission component is in a first position, the second transmission component is in a second position. When the first transmission component is in a third position, the second transmission component is in a fourth position.

[0010] A fixing unit includes a first fixing part driven by the first transmission assembly and a second fixing part driven by the second transmission assembly;

[0011] When the second mold component is in the engagement position, and the first transmission component is driven by the external force to move from the first position to the third position, it synchronously drives the first fixing part, and through the second transmission component drives the second fixing part, so that the first fixing part and the second fixing part are respectively bridged between the first mold component and the second mold component, thereby restraining and positioning the second mold component, and fixing the second mold component in the engagement position. The first fixing part passes laterally between the first surface and the second surface, and the second fixing part passes laterally between the third surface and the fourth surface. Conversely, when the first transmission component is driven by the external force to move from the third position to the first position, it synchronously drives the first fixing part, and through the second transmission component drives the second fixing part, so that the first fixing part no longer passes laterally between the first surface and the second surface, and the second fixing part no longer passes laterally between the third surface and the fourth surface, thereby releasing the restraint exerted by the first fixing part and the second fixing part on the second mold component.

[0012] In the aforementioned fixing device for the mold component, the movement of the first transmission component between the first position and the third position is a linear reciprocating motion.

[0013] In the aforementioned fixing device for the mold component, the movement of the second transmission component between the second position and the fourth position is a linear reciprocating motion.

[0014] The aforementioned fixing device for the mold component, wherein the second mold component includes a receiving space and is located between the second surface and the fourth surface.

[0015] The aforementioned fixing device for the mold component includes a fixing unit having a recessed hole recessed inward from the fourth surface onto the second mold component. When the second transmission component is located at the fourth position, it drives the second fixing part to engage with the recessed hole at one end.

[0016] The aforementioned fixing device for the mold component includes a second fixing part having a post disposed on the second transmission assembly, with one end of the post being inserted into the insertion hole.

[0017] The aforementioned fixing device for the mold component includes a first transmission assembly disposed on the first mold component, a second transmission assembly disposed on the second mold component, and an actuation unit including a separable coupling assembly disposed on the first transmission assembly and the second transmission assembly respectively.

[0018] The aforementioned fixing device for the mold component includes a coupling assembly comprising a hook body and a hook groove that can be hooked or separated from each other, respectively disposed on the first transmission assembly and the second transmission assembly.

[0019] The aforementioned fixing device for the mold component, wherein the first fixing part is constituted by a portion of the first transmission assembly.

[0020] The aforementioned fixing device for the mold component includes an actuating unit comprising two elastic members, which respectively apply force to the first transmission component and the second transmission component, and elastically constrain the first transmission component and the second transmission component to the first position and the second position, respectively.

[0021] In summary, the beneficial technical effects of this utility model are as follows:

[0022] The fixing device for mold components provided by this utility model mainly includes a first mold component, a second mold component, an actuating unit, and a fixing unit. The first mold component and the second mold component are part of a shoe mold, and the second mold component can move between a mating position and a separating position. When in the mating position, the second mold component is mated with the first mold component; conversely, when in the separating position, the second mold component is separated from the first mold component. The fixing unit, located at two different positions of the second mold component in the mating position, straddles the first and second mold components to restrain them and prevent relative displacement.

[0023] The aforementioned effect of the fixing unit is achieved through a first transmission component and a second transmission component included in the actuation unit. The actuation unit uses the first transmission component to receive an external force applied from an external power source and move along a first path under the action of this force, while simultaneously driving the second transmission component to move along a second path. Furthermore, the fixing unit includes a first fixing part driven by the first transmission component and a second fixing part driven by the second transmission component, so that the first fixing part and the second fixing part can move synchronously with the movement of the first transmission component and the second transmission component.

[0024] The first fixing part and the second fixing part are used to fix the second mold component to the first mold component by placing the first fixing part and the second fixing part across the corresponding parts of the second mold component and the adjacent first mold component from two different directions, thereby achieving the effect of fixing the second mold component to the first mold component.

[0025] The first path and the second path can be either linear directions under linear motion or arc trajectories under angular motion.

[0026] The fixed device provides a stable connection between the mold components, improving production efficiency. Attached Figure Description

[0070] The following is in conjunction with the appendix Figure 1-9 The present invention will be described in further detail below.

[0071] First, please refer to Figure 1 and Figure 2 As shown, the fixing device 10 for the mold component provided by this utility model mainly includes a first mold component 20, a second mold component 30, an actuation unit, and a fixing unit 50.

[0072] The first mold component 20 and the second mold component 30 can be mold pieces in a multi-piece mold used to mold shoe soles or mold bases used to support the mold pieces. They can be combinations of mold pieces, combinations of mold pieces and mold bases, or combinations of mold bases, depending on the design of the mold itself. However, the design of the mold itself is not a technical feature of this utility model and is known technology that is widely used. Therefore, it is not necessary to explain it again in this description.

[0073] Through the linkage between the actuating unit and the fixing unit 50, the external force provided by a single power source creates a restraining and positioning effect on the first mold component 20 and the second mold component 30 at two different locations. For example... Figure 2 The dashed line indicates that the second mold component 30, which moves in the direction of gravity, is bridged between the adjacent sides of the first mold component 20 and the second mold component 30 at two different horizontal positions A and B by the first fixing part 51 and the second fixing part 52 included in the fixing unit 50, thereby constraining and binding the second mold component 30 to the first mold component 20 and preventing the separation of the second mold component 30 and the first mold component 20. The two different positions A and B can be parallel opposing sides or adjacent adjacent sides, depending on the needs of the mold.

[0074] Please see Figures 3 to 9 As shown, the present invention will further describe the above-mentioned technical content in detail with a specific preferred embodiment. The first mold component 20a includes a plate-shaped mold base 21a, a first mold piece 22a of appropriate thickness is attached and fixed to the bottom side of the mold base 21a from the upper side, a first hole 23a extends upward from the lower side of the first mold piece 22a and is provided on the first mold piece 22a, and a second hole 24a extends to the left from the right side edge of the first mold piece 22a and is provided on the first mold piece 22a and communicates with the first hole 23a.

[0075] The second mold component 30a is only partially shown in the figure. In specific applications, the second mold component 30a can be a shoe last mold body used to fit or mold the shoe body (not shown in the figure), and includes a connecting part 31a protruding from the top of the shoe last mold body. The shape of the connecting part 31a can be smoothly inserted into the first hole 23a, so that the second mold component 30a can move between a connecting position and a separating position in the axial direction of the first hole 23a.

[0076] like Figure 7 As shown, when the second mold component 30a is in the mating position, the mating part 31a is embedded in the first hole 23a, and a first surface 25a of one side of the hole wall of the first hole 23a and a second surface 32a of one side of the mating part 31a are adjacent to each other, and a third surface 26a of the other side of the hole wall of the first hole 23a and a fourth surface 33a of the other side of the mating part 31a are adjacent to each other.

[0077] Furthermore, the joint 31a includes a body 311a that can be smoothly inserted into the first hole 23a, and a third hole 312a is straight through the body 311a, with openings formed on the second surface 32a and the fourth surface 33a respectively. When the second mold member 30a is in the joint position, the third hole 312a and the second hole 24a are coaxially corresponding.

[0078] When the second mold component 30a is in the separated position, the connecting part 31a moves downward along the hole axis of the first hole 23a and out of the receiving space provided by the first hole 23a, thereby separating the second mold component 30a from the first mold component 20a.

[0079] The actuation unit 40a includes a first transmission component 41a and a second transmission component 42a for transmitting externally applied forces. The first transmission component 41a is in the shape of a straight rod, with a first rod body 411a slidably disposed in the second hole 24a, and a first end 412a located at one end of the first rod body 411a extending out of the first mold member 20a to receive externally applied forces, so that the first transmission component 41a can reciprocate linearly between a first position and a third position along the hole axis of the second hole 24a under the action of external forces.

[0080] The second transmission component 42a is also in the shape of a straight rod, and is slidably disposed in the third hole 312a with a second rod body 421a. A second end 422a located at one end of the second rod body 421a extends out of the opening of one end of the third hole 312a. The second end 422a can receive the external force transmitted from the first transmission component 41a, so that it can move linearly back and forth between a second position and a fourth position along the hole axis in the third hole 312a.

[0081] Since the second transmission component 42a is disposed in the second mold component 30a, in order to keep the second mold component 30a active in the engagement position and the disengagement position, and to ensure that the external force can be transmitted smoothly when it is in the engagement position, in this embodiment the actuation unit 40a further includes a coupling assembly 43a, which serves as the transmission structure between the first transmission component 41a and the second transmission component 42a.

[0082] The coupling assembly 43a includes an annular hook 431a protruding radially from a second end 422a, and a groove 432a recessed radially from a first rod 411a, adjacent to a third end 413a at the other end of the first rod 411a. An axial opening 4321a is formed on the third end 413a, and a radial opening 4322a is formed on the first rod 411a. The inner diameter of the axial opening 4321a is smaller than the outer diameter of the hook 431a but greater than or equal to the second end 422a. The outer diameter of the outer diameter of the radial opening 4322a is greater than or equal to the outer diameter of the hook body 431a, and the opening direction of the radial opening 4322a is downward, so that the hook body 431a can be inserted into the hook groove 432a from the radial opening 4322a while the second mold component 30a moves from the separation position to the engagement position, and the second rod body 421a is accommodated by the axial opening 4321a, so that the first transmission component 41a and the second transmission component 42a can be connected to each other through the coupling assembly 43a to transmit external force.

[0083] The fixing unit 50a includes a first fixing part 51a, a second fixing part 52a, and a recess 53a. The first fixing part 51a is formed by a portion of the first transmission assembly 41a. Specifically, the first fixing part 51a is defined by a portion of the first rod body 411a adjacent to the third end 413a. The second fixing part 52a includes a post 521a, which is coaxially fixed to the rod shaft end of the second rod body 421a. The recess 53a is a blind hole, which is coaxially recessed into the first template 22a from the third surface 26a along the second hole 24a.

[0084] With the above-mentioned components, the fixing device 10a of the mold component is used to fix the mold base 21a to a common mold clamping mechanism, thereby positioning the first mold component 20a. The second mold component 30a, taking the shoe last mold as an example, can move between the separation and engagement positions. When the second mold component 30a moves from the separation position to the engagement position, the first transmission component 41a is located in the first position and the second transmission component 42a is located in the second position, and the radial opening 4322a is located within the hole space of the first hole 23a, and the radial opening 4322a faces downward. When the second mold component 30a moves to the engagement position, the hook body 431a and the second end 422a of the second rod body 421a can be inserted into the hook groove 432a from the radial opening 4322a, so that the first rod body 411a in the first position and the second rod body 421a in the second position are coaxially engaged with each other.

[0085] When an external force is applied to the first end 412a by a known power source such as a fluid pressure cylinder or a motor, the first transmission component 41a moves axially from the first position to the third position, which in turn drives the second transmission component 42a to move axially from the second position to the fourth position. The fixing unit 50a also moves accordingly, so that the first fixing part 51a passes laterally through the first surface 25a and the second surface 32a, and the second fixing part 52a passes laterally through the third surface 26a and the fourth surface 33a. This forms a bridging and fixing state at two different positions between the joint 31a and the first mold piece 22a, achieving a fixing and bonding effect at least at two different positions with a single external force, making the bonding between different mold components more stable.

[0086] In addition, to ensure that the first transmission assembly 41a is in the first position and the second transmission assembly 42a is in the second position when the actuation unit 40a is not in use, two elastic elements 44a and 45a, such as springs, can be respectively sleeved on the first rod body 411a and the second rod body 421a. The parts of the first mold member 20a and the second mold member 30a can be used as support points to provide appropriate elastic force to the first transmission assembly 41a and the second transmission assembly 42a, so that they are elastically restrained in the first position and the second position when not subjected to external force.

[0087] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
