Description

[Technical Field]

[0001] This invention relates to the field of thermosetting molds, and more particularly to a runner plate water channel system for thermosetting material molds. [Background Technology]

[0002] Thermosetting materials soften and flow only during the first heating. After being heated to a certain temperature, they undergo a chemical reaction—cross-linking and solidification—and harden. This change is irreversible; subsequent heating will not allow them to soften and flow again. When casting thermosetting materials, they are typically delivered to the runner plate, then transferred through the gate on the runner plate to the sprue bushing, and finally fed into the mold cavity for thermosetting. However, throughout the production process, the mold cavity maintains a high temperature, which is easily transferred to the runner plate and sprue bushing. When the temperature of the runner plate and sprue bushing is high, the thermosetting material inside tends to harden gradually from its softened state. This undoubtedly hinders the flow of the thermosetting material in the runner plate and sprue bushing, affecting the overall processing efficiency and potentially clogging the runner plate and sprue bushing. [Summary of the Invention]

[0003] The purpose of this invention is to overcome the above-mentioned problems. We provide a runner plate water channel system for thermosetting material molds, which sets a circulating cooling water channel system in the runner plate and the sprue bushing to ensure that the temperature of the runner plate and the sprue bushing will not be too high during the production process of thermosetting material molds.

[0004] To achieve the above objectives, the present invention provides a runner plate water channel system for a thermosetting material mold, characterized in that: it includes a runner plate, a first water channel, and a second water channel; each gate of the runner plate is provided with a gate sleeve; a cooling water channel is provided inside the runner plate; the outlet of the first water channel is connected to the inlet of the cooling water channel; the inlet of the second water channel is connected to the outlet of the cooling water channel; a cooling water cavity connected to the first or second water channel is provided inside the gate sleeve; a water guide portion dividing the cooling water cavity into two chambers is provided in the cooling water cavity; the top of the water guide portion extends upward to cut off the first or second water channel; and the bottom of the water guide portion forms a water guide channel with the bottom of the cooling water cavity.

[0005] In one or more embodiments, the water guide divides the cooling water chamber into two chambers of equal size.

[0006] In one or more embodiments, the cooling water cavity is cylindrical or rectangular.

[0007] In one or more embodiments, the water guiding portion is a water guiding plate.

[0008] In one or more embodiments, the first water channel and the second water channel are formed in the upper mold pad, and the runner plate and the sprue sleeve are detachably fixed to the upper mold pad.

Detailed Implementation Methods

[0021] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0022] Please refer to Figure 1-6 This invention provides a runner plate water channel system for a thermosetting material mold, comprising a runner plate 1, a first water channel 2, and a second water channel 3. Each gate of the runner plate 1 is provided with a gate sleeve 4. Cooling water channels are provided inside the runner plate 1, which are arranged around or fill the interior of the runner plate to maximize the cooling of the runner plate 1. The outlet of the first water channel 2 is connected to the inlet 11 of the cooling water channel, and the inlet of the second water channel 3 is connected to the outlet 12 of the cooling water channel. The gate sleeve 4 is provided with a cooling water cavity 5 that communicates with the first water channel 2 or the second water channel 3. The cooling water cavity 5 is provided with a water guide 6 that divides it into two chambers. The top of the water guide 6 extends upward and cuts off the first water channel 2 or the second water channel 3, and the bottom of the water guide 6 forms a water guide channel with the bottom of the cooling water cavity 5.

[0023] The water flow principle in this embodiment is as follows: Water from the first water channel 2 first flows through each sprue sleeve 4 connected to the first water channel 2. When it flows into the first connected sprue sleeve 4, refer to the appendix. Figure 3 The water first flows into one of the two chambers separated by the water guide section 6, then through the bottom water guide channel, flows into the other chamber, and then returns to the first water path 2. Each sprue sleeve 4 connected to the first water path 2 flows in this manner in sequence. Then, the water in the first water path 2 enters the cooling water path in the runner plate 1, and the water in the cooling water path flows into the second water path 3. The water outlet principle of the sprue sleeve 4 connected to the second water path 3 is the same as that of the sprue sleeve connected to the first water path 2, and will not be repeated here. The water system of this embodiment can perform a water circulation cooling and temperature reduction on the runner plate 2 and each sprue sleeve 4, allowing the water flow to carry away their heat, ensuring that the heat of the runner plate 2 and the sprue sleeve 4 is not too high, and ensuring that the thermosetting material inside can enter the cavity in a softened and flowing state.

[0024] Preferably, the water guide section 6 divides the cooling water chamber 5 into two chambers of equal size. These equal-sized chambers ensure a balance between inlet and outlet water flow, facilitating smooth water delivery. The cooling water chamber 5 is cylindrical or rectangular. Both cylindrical and rectangular shapes are symmetrical and easier to manufacture. The water guide section 6 only needs to be positioned in the middle of the cylindrical or rectangular cooling water chamber 5 to effectively divide it into two chambers of equal size. The water guide section 6 is a water guide plate, which can be made of stainless steel.

[0025] Specifically, the first water channel 2 and the second water channel 3 are formed in the upper mold pad 7. The runner plate 1 and the sprue sleeve 4 are detachably fixed on the upper mold pad 7. The first water channel 2 and the second water channel 3 can be formed by drilling strip holes in the upper mold pad 7.

[0026] Preferably, the upper mold pad 7 has a runner plate mounting port 8 on its side wall, and a runner plate ejection mechanism 9 is provided on the side of the upper mold pad 7 opposite to the runner plate mounting port 7. The runner plate ejection mechanism 9 is a push pin. When the mold stops production, thermosetting material will inevitably remain in the runner plate 1. After the mold stops, the cooling system does not work, and the preheating in the cavity will be transferred to the runner plate 1. Therefore, after each mold stops production, it is necessary to disassemble the entire upper mold part and then remove the runner plate 1 for cleaning. However, this solution uses the runner plate mounting port 8 and the ejection mechanism 9 to remove or install the runner plate 1 from the runner plate mounting port 8, which can avoid the troublesome problem of disassembling the entire upper mold part when cleaning the waste material in the runner plate 1 during shutdown. On the one hand, the runner plate 1 can be quickly disassembled and assembled. On the other hand, simply removing the runner plate 1 will not affect the connection accuracy of the various components of the upper mold part.

[0027] Preferably, the gate 10 of the runner plate 1 is located on the side, and the side of the gate sleeve 4 is provided with a feed port 13 that connects with the gate 10. Specifically, the connection surface between the gate 10 and the feed port 13 is an inclined surface. The difference between an inclined surface and a straight surface (perpendicular to the horizontal plane) is that a straight surface is prone to material leakage, while an inclined surface has a tighter connection and is less prone to material leakage.

[0028] Preferably, the sprue sleeve 4 is provided with a sealing mechanism at the connection between the cooling water cavity 5 and the first water channel 2 or the second water channel 3. Specifically, the sealing mechanism includes a first sealing ring 14 and a second sealing ring 15. The first sealing ring 14 is disposed in the second sealing ring 15, and the connection is located between the first sealing ring 14 and the second sealing ring 15, thereby enhancing the sealing performance of the connection and preventing water in the water channel from leaking out of the mold.

[0029] In addition to the above embodiments, the present invention may have other implementation methods. Technical solutions formed by equivalent substitution or equivalent transformation all fall within the protection scope of the present invention.
