Description

Technical Field

[0001] This utility model relates to the field of shoe molds, specifically a shoe sole mold with balanced control of multi-segment clamping force. Background Technology

[0002] The shoe sole mold is mainly locked by applying locking force through a robust mold closing base structure. This structure is designed to be robust and uses a hydraulic system to independently control the pressure, ensuring that the mold is tightly closed during injection without leaking plastic. The locking process is usually carried out in two stages. The first stage is a rapid closure to reduce time, and the second stage applies high-pressure locking force to avoid damaging the mold and improve efficiency. At the same time, the system precisely adjusts the injection pressure and speed through proportional independent control to ensure the dimensional accuracy and quality consistency of the shoe sole.

[0003] After long-term use, the precision of the internal components of existing shoe sole molds decreases, which can easily lead to problems such as misalignment of the upper and lower molds during production. Although the offset detection component can detect the offset status in real time, the existing offset detection component has poor mold adaptability and there is room for improvement.

[0025] Example 2:

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4This invention discloses a shoe sole mold with multi-segment clamping force balanced control. Compared to Embodiment 1, this embodiment further includes: a positioning pin 104 fixedly connected to the center of the bottom of the lower mold 101, the lower end of the positioning pin 104 being inserted into the inner side of the positioning groove 105 for convenient centering of the lower mold 101; the positioning groove 105 being located in the center of the inner side of the top surface of the support base 102; multiple sets of first pressure sensors 106 being equidistantly arranged along the diagonal of the rectangular groove on the top surface of the support base 102, and the first pressure sensors 106 being connected to a data transmitter 103 for data transmission; the data transmitter 103 being connected to an external hydraulic system for data transmission, facilitating the adjustment of the clamping force of the hydraulic system on the top surface of the mold by monitoring the pressure at the four corners of the bottom of the mold; and the data transmitter 103 being fixedly connected to the four corners of the outer side of the support base 102. Multiple springs are equidistantly arranged on the left side of the second pressure sensor 209, and the springs are in contact with the inner side of the second mounting arch 207. The sensing surface of the right end of the second pressure sensor 209 protrudes horizontally from the right side of the second mounting arch 207, so that when the mold shifts, the second pressure sensor 209 can effectively collect data and work with the second mounting arch 207 to buffer, thereby avoiding serious damage to the second pressure sensor 209. The vertical limit slide bar 203 and the horizontal limit slide bar 208 are provided with scales on their outer sides, which are convenient for operators to adjust and observe the height. The lower end of the vertical adjustment threaded rod 201 is provided with an adjustment handle. The right end of the protruding plate on the right side of the second mounting arch 207 is provided with a buffer pad to increase buffering and reduce the damage to other mechanical parts caused by the offset impact.

[0027] The working principle of a shoe sole mold based on the multi-segment clamping force equalization control in Embodiment 1 is as follows:

[0028] First, the lower mold 101 is installed in the center of the top surface of the support base 102 via the positioning pin 104 and the positioning groove 105. Then, the operator raises the first mounting arch 202 to the preset height range that meets the mold specifications by using the vertical adjusting threaded rod 201 and the vertical limiting slide rod 203. Then, the mold closing and locking operation is performed by the hydraulic system. Next, the pneumatic push rod 206 output shaft is used in conjunction with the transverse limiting slide rod 208 to push the second mounting arch 207, thereby making the second pressure sensor 209 fit against the outside of the upper mold 100, which facilitates the acquisition of offset data. When the mold is offset, the second pressure sensor 209 collects data while cooperating with the spring on its left side and the second mounting arch 207 to buffer the displacement, thereby avoiding serious damage to the second pressure sensor 209 and immediately sending data to stop the injection molding to reduce subsequent losses.

[0029] Furthermore, after the lower mold 101 is centered and positioned, multiple sets of first pressure sensors 106 arranged in an array monitor the pressure at the four corners of the bottom of the mold. Data is collected uniformly through the data transmitter 103, and then the hydraulic system is synchronously adjusted to balance the clamping force at the four corners of the top surface of the mold, thereby reducing the occurrence of mold offset.

[0030] This invention provides an improved shoe sole mold with multi-segment clamping force equalization control. An offset detection mechanism 200 monitors the side clamping state of the mold. A second pressure sensor 209 is slidably connected to the inner side of the right side of the second mounting arch 207. When the mold shifts, the second pressure sensor 209 effectively collects data while simultaneously buffering the impact with the second mounting arch 207, thus preventing serious damage to the second pressure sensor 209. The mold is centered on the top surface of the support base 102 using a positioning pin 104 and a positioning groove 105. Multiple sets of first pressure sensors 106 arranged in an array monitor the pressure at the four corners of the bottom of the mold, thereby synchronously adjusting the hydraulic system to equalize the clamping force at the four corners of the top surface of the mold, reducing mold shifting.
