Description

Technical Field

[0001] The utility model relates to the technical field of shaping, in particular to a plastic sole manufacturing forming mould. Background Art

[0002] During the processing of rubber soles, the soles are shaped by molds. During the shaping operation, the material will be placed inside the sole mold and distributed in the mold cavity by heating. Since the rubber material of the rubber sole is relatively soft and easy to deform, it is easy to stick to the mold. If an ejector device is used to eject the rubber sole in the mold, the ejector pin of the ejector device is easy to insert into the rubber sole, causing damage to the rubber sole. Therefore, the rubber sole is taken out manually, but the rubber sole will stick to the mold cavity, which is extremely inconvenient to take out. For this reason, we propose a plastic sole manufacturing mold. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a molding die for manufacturing a plastic sole.

[0004] The utility model provides the following technical solution: a plastic sole manufacturing forming mold, comprising a fixed mold, an intermediate mold and a movable mold, wherein both sides of the fixed mold, the intermediate mold and the movable mold are connected by an X-shaped folding frame;

[0005] The top end of the fixed mold and the bottom end of the movable mold are both provided with mold cavities for the upper and lower surfaces of the plastic sole;

[0006] The middle mold is provided with two symmetrically distributed movable openings, and slidable templates are provided in the two movable openings. The middle mold between the two movable openings is provided with two symmetrically distributed half mold grooves A, and the opposite surfaces of the two templates are provided with half mold grooves B. When the mold grooves A and B are combined, a complete mold groove of the plastic sole is formed;

[0007] Both templates are provided with inclined through-holes, and the top of the fixed mold is provided with two inclined guide pillars. When the through-holes on the templates move down along the guide pillars and the bottom ends contact the fixed mold, mold grooves A and B merge and correspond to the mold cavities on the fixed mold. When the through-holes on the templates detach from the guide pillars, mold grooves A and B separate.

[0008] Preferably, when the X-shaped folding frame is opened and retracted, the spacing between the bottom plate, the middle plate and the top plate is the same.

[0009] Preferably, a magnet is provided at one end of the two movable openings away from the A-mold groove, and the magnet adsorbs the template for positioning.

[0010] Preferably, a slide rail is provided in the movable opening, and the template slides in the movable opening via the slide rail.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The plastic sole manufacturing molding mold, after the material is molded in the mold cavities of the fixed mold, the middle mold and the movable mold, the upward movement of the movable mold will drive the X-shaped folding frame to move the middle mold upward accordingly, and the middle mold will be separated from the fixed mold, which will cause the two mold plates on the middle mold to move outward along the guide column to separate the mold grooves on the middle mold. The mold cavities on the fixed mold and the movable mold are very shallow, so if the plastic sole is adhered to them, it is easy to take it out. If the plastic sole is adhered to the middle mold and the mold grooves on the middle mold are separated, it is easier to take out the plastic sole. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of known functions and known components to avoid unnecessary confusion of the concepts of the present invention.

[0018] See also Figure 1-3 , a plastic sole manufacturing molding die, comprising a fixed die 1, an intermediate die 2 and a movable die 3, wherein both sides of the fixed die 1, the intermediate die 2 and the movable die 3 are connected by an X-shaped folding frame 4;

[0019] The top of the fixed mold 1 and the bottom of the movable mold 3 are both provided with mold cavities 5 for the upper and lower surfaces of the plastic sole, and the mold cavities 5 on the fixed mold 1 and the movable mold 3 are very shallow, so the plastic sole can be easily removed if it is adhered thereto, and the plastic sole can be removed by manual pulling, which is relatively more convenient.

[0020] The middle mold 2 is provided with two symmetrically distributed movable openings 21, and the two movable openings 21 are each provided with a slidable template 22, and the middle mold 2 between the two movable openings 21 is provided with two symmetrically distributed half A mold grooves 23, and the opposite surfaces of the two templates 22 are each provided with half B mold grooves 24, when the A mold groove 23 and the B mold groove 24 are combined to form a complete mold groove of the plastic sole;

[0021] Both templates 22 are provided with inclined through-holes 25, and the top of the fixed mold 1 is provided with two inclined guide pillars 26. When the through-holes 25 on the template 22 move down along the guide pillars 26 and the bottom end contacts the fixed mold 1, the A mold groove 23 and the B mold groove 24 merge and correspond to the mold cavity 5 on the fixed mold 1. When the through-holes 25 on the template 22 are detached from the guide pillars 26, the A mold groove 23 and the B mold groove 24 are separated, and the template 22 moves on the guide pillars 26, so that the mold grooves on the intermediate mold 2 complete the merging process.

[0022] A magnet 27 is provided at one end of the two movable openings 21 away from the A-mold groove 23, and the magnet 27 attracts the template 22 for positioning. When the template 22 is separated from the guide post 26, the template 22 just rests on the magnet 27, and the template 22 is attracted by the magnet 27 to prevent the template 22 from moving. When the template 22 moves downward, the through opening 25 on it just contacts the guide post 26 again.

[0023] A slide rail 28 is provided in the movable opening 21 , and the template 22 slides in the movable opening 21 via the slide rail 28 .

[0024] When the X-shaped folding frame 4 is opened and contracted, the spacing between the bottom plate 1, the middle plate 2 and the top plate 3 is the same. After the material is formed in the mold cavities of the fixed mold 1, the middle mold 2 and the movable mold 3, the upward movement of the movable mold 3 will drive the X-shaped folding frame 4, so that the middle mold 2 moves upward accordingly, thereby separating the fixed mold 1, the middle mold 2 and the movable mold 3.

[0025] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
